What are the advantages and disadvantages of BYD Han EV with good sales in new energy vehicles?

According to relevant data, in December 2021, BYD sold 13,701 Han models, including 10,301 Han EV (parameter picture) and 3,400 Han DM.

Today, let’s take a look at the advantages and disadvantages of BYD Han EV with good sales.

Advantage 1: the feeling of pushing back brought by strong power

As a pure electric vehicle, BYD Han EV perfectly has the very rapid starting acceleration ability brought by the high torque output of electric vehicle motor. The official acceleration score of 100 kilometers takes only 3.9 seconds, and this performance can even be compared with luxury and super-running. For users, what is more important is probably the strong sense of pushing back brought by this strong power.

Question 1: The charging noise is loud.

The so-called super charging technology of BYD Han EV has some problems in actual use, the prominent one is the loud noise, and the design of the charging head of BYD Han EV is not reasonable, so charging is relatively inconvenient.

Problem 2: The assisted driving is not perfect.

Generally speaking, new energy vehicles have more obvious advantages in intelligence than traditional fuel vehicles. However, BYD Han EV is not only an L2-level automatic driving assistance system, but also does not perform well in actual driving. For example, Han EV can’t turn on ACC alone, but must keep driving together with the lane. For example, Han EV’s lane line recognition is not in place, and it can’t be used as long as the road conditions are almost the same.

Problem 3: The brake foot feels bad.

Perhaps the coordination between BYD Han’s energy recovery system and braking is not done well, which leads to its stiff foot feeling at the beginning and end of braking, and even a "nod" situation.

Question 4: The actual cruising range has shrunk seriously.

Like many new energy vehicles, BYD Han EV also has a shortened cruising range. Due to congenital factors such as structure, it is difficult to ensure its power-off speed even if Han EV adds many insulation measures, especially in winter and colder northern regions. According to the feedback from car owners, the official cruising range of 550 kilometers is only 400 kilometers, and most car owners say it can only reach about 350 kilometers.

Question 5: The accelerator pedal area is too small.

Byd Han also has a very serious safety problem, that is, the distance between the pedal and the baffle used to protect the mechanical structure above is too close. Basically, as long as the foot is about 40 yards, the toe will touch the protective plate if the foot is slightly lifted up. However, if you switch between braking and throttle very quickly and frequently in the actual driving process, your feet will basically hit the protective plate every time, which is very easy to cause misoperation of driving and affect driving safety.

Problem 6: Too comfortable chassis adjustment affects vehicle handling.

In terms of suspension, BYD Han EV adopts the multi-link suspension structure before McPherson. Although some people call it the "chopsticks" chassis, you will know that this statement is not true after driving BYD Han EV. The main problem of BYD Han EV chassis is that it is too comfortable to adjust, which will make it difficult for drivers to control the vehicle perfectly when the vehicle is accelerating rapidly, which is obviously incompatible with BYD Han EV’s strong acceleration power from the aspect of maneuverability.

Problem 7: The rotary central control panel is not practical.

The central control panel in BYD Han EV car adopts a rotary design, which sounds cool, but in fact, it is very practical, and this function is basically not needed for daily driving. Han EV integrates most of the functions inside the vehicle into the central control panel, but its touch performance is not so good, and the car system also has the problems of slow running speed and many bugs. In this case, it is very inconvenient to have no physical buttons in the car.

Question 8: Small trunk space.

Because the battery pack occupies part of the space, even compared with most new energy vehicles, BYD’s trunk space is still relatively small, with weak loading capacity and good practicability. In addition, there is no trunk in the front cabin of BYD Han EV, mainly because BYD Han still has a DM version, so it must be compatible with oil and electricity. For the sake of placing an engine and gearbox in the front cabin, the front cabin of BYD Han has to be similar to the traditional model, and the final result is that BYD Han still has certain limitations in the front cabin design.

Guangzhou Automobile has no map, pure vision and intelligent driving to build an electrified highland of global automobile industry

On April 12th, on Technology Day 2024, a number of breakthrough technologies were launched. For example, the pure visual intelligent driving system and all-solid-state driving system, which are not shown in the figure, are planned to be mounted on vehicles in 2026.

In addition, the scene also showed many technologies, such as, first class, 0.0 odd machine core intelligent chassis, flying car and so on.

Let’s look at all-solid-state batteries first. As the core component, power battery is directly related to key indicators such as cruising range and safety. The development of power battery technology is also a technical highland for the electrification transformation of the global automobile industry.

GAC all-solid-state power battery adopts solid-state anode technology with high area capacity and third-generation sponge silicon anode technology (new composite anode). Compared with the current top liquid, its volume energy density and mass energy density are improved. If it exceeds 50%, the cruising range of the vehicle can be stably exceeded, and it is expected to be carried on a good model in 2026.

In terms of safety, GAC’s all-solid-state power battery adopts high-strength and compact composite membrane. During the hot box test at 200℃, the battery does not explode, setting a new height battery for high specific energy safety.

In terms of capacity, the all-solid-state power battery realizes the manufacture of large-size multi-layer stacked all-solid-state batteries. Its capacity reaches 30Ah, far exceeding the highest level in the industry (10Ah-15Ah). It is a vehicle-class all-solid-state power battery. The application of batteries laid the foundation.

Let’s look at the house of five pictures again.

According to the data provided, at present, the coverage rate of high-precision maps on all roads in the market is only 6%, which means that 94% of roads cannot rely on high-precision maps to achieve accurate and intelligent driving. Driving. Therefore, starting from this year, intelligent driving without maps has become a new trend.

Compared with the current mainstream technology route, the map-free pure visual intelligent driving system launched by GAC on this Science and Technology Day not only does not need high-precision maps, but also does not rely on them. Instead, it combines with AI algorithm and feels like human beings. In the world, it is easier to achieve wider intelligent driving coverage.

It is reported that this system can accurately identify and understand the structure of roads, whether it is ramps, tunnels, bends, intersections, forks and other complex scenes.

Secondly, the system realizes the accurate identification of various signal light elements, including signal light type, various symbols and colors, countdown, flashing state and so on.

Thirdly, the sensing range of the system reaches more than 150 meters in front of the car, 100 meters behind the car and 50 meters around, which is 1.5 times of the industry level. In addition to common traffic factors such as vehicles, pedestrians, riders and small animals, the sensing category also includes small carts. Irregular obstacles such as vehicles and camping tents.

In the parking scene, the minimum error of the system can be controlled at 5cm, which can realize the most difficult three-dimensional parking space and narrow parking space in the industry.

It is worth noting that GAC has laid out two major technical routes in the field of autonomous driving technology: mainstream "multi-fusion technology" and forward-looking "map-free pure vision technology", both of which will get rid of dependence on high-precision maps.

In addition to the above-mentioned technologies to build core competitiveness, Guangzhou Automobile Group has also brought more imaginative new technologies.

Such as flying cars. Previously, Guangzhou Automobile Group’s first flying car, GOVE, achieved the world’s first flight on Guangzhou Automobile Science and Technology Day last year, and conducted a flight demonstration in the sky in March this year, completing the flight verification time in a complex low-altitude city public environment for the first time.

GAC’s new light business segment, SINOMACH, was also officially released on this Science and Technology Day. The Qiqi First Class exhibited this time supports L2-L4 intelligent driving and will be mass-produced this year.

According to public data, in 2023, Guangzhou Automobile Group invested nearly 8.4 billion yuan in independent research and development, and applied for nearly 3,200 new patents, accounting for about 50%. Up to now, the cumulative investment in independent research and development over the years has exceeded 45 billion yuan.

On the crowded intelligent electric track, GAC Aian is one of the few independent car companies that can surpass the new forces in the leaderboard. At this moment, it is time for the major national giants to catch up.

Product Experience Report: The Elf on the Wrist-mi band 4

This article is mi band’s product experience report, which mainly focuses on the following aspects: product analysis, functional experience, operation strategy and competing product analysis, etc. It is a product experience report with clear and complete ideas to share with you.

This experience report mainly includes two purposes: first, deeply experience mi band and Xiaomi Sports APP, and systematically understand the functions of mainstream bracelets; Secondly, by thinking about the existing function of the bracelet, we explore the needs and significance behind the function and improve our product perception.

According to IDC monitoring data, from 2012 to 2018, global wearable device shipments showed a rapid growth trend. In the fourth quarter of 2018, global wearable device shipments were 59.3 million units, a year-on-year increase of 31.4%. In 2018, global wearable device shipments reached 172.2 million units, a year-on-year increase of 27.5%.

According to IDC’s forecast, the shipment of smart bracelets in 2019 is expected to be 54.2 million, accounting for 24.3% of the annual market. In the next five years, this market will maintain a state of no increase or decrease. By 2023, there will be 55 million smart bracelets in the world, accounting for 18.2% of the overall market, with a compound growth rate of about 0.3% in five years.

Although the growth rate of smart bracelets has slowed down, we can see that many bracelet manufacturers are taking advantage of low price and portability to make this product shine in specific industry applications.

A smart wearable device with outstanding endurance, which provides users with services such as sports record, health data management and mobile phone message synchronization, not only meets the needs of mass users for health data management and mobile phone message synchronization, but also meets the needs of users who love sports to record and share sports conditions.

According to the crowd portrait of Baidu Index, among the users in mi band,There are more male users, accounting for 69.11% of the total users, which is caused by the obvious difference in the cognition of cost performance between male users and female users. Xiaomi’s high cost performance comes from more competitive parameters at the same price, while the audience of equipment parameters is mainly male users.

Judging from the age distribution of users,The age group of users is mainly between 17 and 35 years old., including young students and office workers. This group of people has the characteristics of great economic pressure, long-term sedentary and love of sports.

According to the regional popularity of users, users in mi band are mainly distributed in Beijing, Shanghai, Guangzhou and other cities, followed by Hangzhou, Shenzhen and Chengdu. In generalUsers are mainly concentrated in first-tier cities and new first-tier cities.Users in these cities have a high degree of acceptance of science and technology products and are willing to pay for improving their quality of life.

Imagine the following typical user scenarios according to the target users:

Scene 1:

  • Target user: male, post-90 s, office worker, coordinates of Beishangguang. The source of income is salary, which is mainly used for rent, daily expenses and friends’ entertainment expenses. Busy with work on weekdays, commuting to home and company at two o’clock and one line, without too much spare time.
  • Typical usage scenario: NFC and Alipay payment functions were opened at the first time after getting the bracelet. Every morning and evening, you don’t have to take out your mobile phone and badge when you rush to the subway, punch in at work and buy food at noon. You can just use your bracelet to swipe your card and pay, which improves the convenience of life.

Scene 2:

  • Target users: male, born in 1990s, college students, in first-and second-tier cities. The monthly living source is mainly the living expenses given by parents, pursuing cost performance, loving electronic products and sports, and relaxing by running and swimming when there is no class.
  • Typical usage scenario: The mobile phone is not easy to carry when exercising, and it often interferes with one’s own exercise. Therefore, mi band, who has a relatively high price, is bought to record one’s exercise data, so as to understand the details of one’s exercise and conduct more targeted training.

Scene 3:

  • Target users: male, born after 1985, rice noodles, first-tier cities. The source of income is the salary at work, and both husband and wife share the mortgage and family daily expenses. At the same time of careful calculation, we pursue the quality of life. There are many Mijia smart homes such as humidifiers, sweeping robots and chandeliers at home.
  • Typical usage scenario: Before going to bed at night, I found that the room was very dry and forgot to turn on the humidifier in the bedroom. At the same time, the chandelier in the bedroom was not turned on. At this time, I was sleepy and didn’t want to get out of bed, so I woke up Xiaoai, a classmate with a bracelet, to turn on the humidifier remotely and turn off the chandelier to create a comfortable sleeping environment.

Scene 4:

  • Target users: female, post-90s, college students, first-tier cities. I like shopping and taking photos at ordinary times, and I am keen on some cute little things with a sense of technology. I am used to watching the time with my watch.
  • Typical usage scenario: I am used to watching time with a watch, and I know that Xiaomi 4 bracelet has not only the function of watching time, but also the function of message synchronization and NFC, so I successfully pulled out the Xiaomi 4 bracelet with colorful wristbands. After purchase, I am very interested in the cartoon theme of the dial in addition to the daily time watching and message synchronization functions, and will change the theme of the dial from time to time.

According to KANO Kano model, the functions that meet the basic needs of users are listed as basic functions, and the functions that meet the expected and exciting needs of users are listed as characteristic functions.

Mi band’s sports data records cover outdoor running, indoor running, cycling, walking, exercise, swimming and other sports modes. This experience analysis takes the most common outdoor running as the main experience scene, and describes the functional details of different stages according to the processes before, during and after running.

(1) Before running

1) Start running records in two ways to meet the needs of differentiated users.

Users can enter the running record function through mi band and Xiaomi Sports APP, which adapts to the running habits of different users.

When the user operates through the bracelet, because the information carried by the bracelet screen is limited, the user needs to slide the menu several times to search step by step. After entering the page, the bracelet will detect the connection and positioning with the mobile phone. After the positioning is successful, the user can confirm and start running.

In contrast, it will be much simpler to operate through Xiaomi Sports APP. Users can directly call up mi band’s running record page by clicking the running page BTN "Go", and can realize multi-terminal recording of bracelets and mobile phones.

2) The running interface has single function.

Xiaomi Sports APP calls the running record path of the bracelet, although it is simple, but the interface function is slightly simple. You can consider adding functions such as warm-up guidance before running, one-click listening to songs, and popular routes.

The warm-up guidance function can help users to complete the pre-run preparation work more professionally and avoid strain; For users who use the running recording function, most of them are long-distance running users, that is, more than 3km. The accompaniment of music can cultivate the rhythm of running, adjust the breathing rhythm, and make the running process no longer lonely; For some users who don’t like simplification and are willing to constantly explore new venues, they can recommend popular routes with their accessories to increase the motivation and interest of running.

(2) Running

1) Automatic pause to optimize the running experience.

When the user starts the running recording function through Xiaomi Sports APP, the user’s current state can be judged according to the user’s pace data. If the user pauses during running, the bracelet will automatically pause the recording. The intelligent pause function helps users to save the operation process of manual pause, so that users can switch between running and midway rest, and at the same time improve the authenticity of bracelet data records.

At present, the automatic pause function is only supported when the running record mode is started by the millet movement on the mobile phone. It may be considered that mi band has no built-in GPS module, and the coverage scenes and terminals of this function can be increased after the follow-up technology is feasible.

2) Pace metronome makes running more professional.

Pace metronome is mainly to meet the needs of professional runners to improve their pace and control their running frequency. This function is mainly transmitted to users through Xiaomi Sports APP. Users need to wear headphones. Users can customize the number of steps and adjust their running speed according to the frequency of beats in headphones.

3) You can’t control the music playing during running.

Most users have the habit of listening to songs while running. When they need to cut songs when they hear songs they don’t like, taking out their mobile phones will interfere with their running process, so it is much more convenient to cut songs with bracelets. However, at present, the running recording function and the music playing control function can not be parallel at the same time, which can not meet the needs of users to cut songs with bracelets when running.

4) The dynamic running information at both ends is not synchronized.

At present, Xiaomi Sports APP can synchronize the static data information of the bracelet users after the end of sports, but the synchronization of dynamic information in sports needs to be strengthened.

When the running record function is turned on in mi band, the running record function of Xiaomi Sports APP will be turned on during running. At this time, the running information of the currently connected bracelet will not be synchronized in Xiaomi Sports APP, but a new running information will be recorded based on the opening time.

(3) After running

1) Provide multiple data analysis dimensions.

Data statistics include the overall statistics according to the time dimension and the detailed statistics of each running record, which are presented in a combination of graphics and words, so that users can understand the detailed information of a certain cycle and a certain exercise at a glance and provide effective information for users to manage their own health. At present, monthly statistics does not support users to find the data statistics of the specified month, and this detailed function needs to be improved.

2) automatically trigger the share button after the screenshot of Xiaomi mobile phone.

When users use the screenshot function of Xiaomi’s mobile phone system, they will generate shared pictures and automatically jump to the sharing page, which is easier for users to share and also improves the exposure of mi band.

3) Post-run stretching course has not been provided yet.

Users will basically stretch after running, but the running page in Xiaomi app does not provide stretching courses. The course of Xiaomi sports is placed in the "course" tab independently, lacking close integration with user behavior.

The bracelet mainly analyzes the sleep state through the body motion recorder, that is, through gravity sensors and sensors to conduct the wearer’s body motion frequency to analyze the sleep state.

(1) Function description

Users can experience the sleep monitoring function when they wear a bracelet to sleep. On the sleep record page of Xiaomi Sports APP, information such as the user’s sleep duration, sleep score, deep sleep and shallow sleep duration, sleep analysis, sleep regularity and sleep analogy of similar users will be provided.

The statistics function at the bottom of the page can show the user’s sleep duration in the form of histogram according to different time periods, so that users can intuitively understand the recent sleep rules.

(2) Functional thinking

Thinking 1: Due to the technical limitations of the bracelet and different personal constitutions, the absolute value data of the best sleep structure is not directly given, but the comparative data of sleep among users is given, so that users can have a clearer positioning of their sleep status;

Thinking 2: Adding today’s feedback function at the bottom of the page is a bright spot. Through the daily feedback of users, the calculation rules of sleep score can be positively corrected, making sleep score more accurate;

Thinking 3: The content of sleep quality analysis is general and lacks pertinence. Considering that it may be limited by existing technology, data and other aspects, with the improvement of hardware equipment, the module will be more intelligent;

Thinking 4: At present, mi band only supports sleep recording at night, but does not support sleep monitoring function during the day. On the one hand, it is speculated that the nap time during the day is short, there are fewer users who fall asleep during the day, and the demand is small; On the other hand, the black-and-white upside-down routine is contrary to the theme of Xiaomi’s healthy life.

(1) Function description

The message synchronization function of mi band allows users to start the message synchronization service of incoming calls, SMS and APP according to their own needs. When the message is received on the message screen of the mobile phone, the bracelet will vibrate to remind users.

This function provides great convenience for users who are inconvenient to check messages when their mobile phones are in their pockets, and users who are used to mute their mobile phones but don’t want to miss important calls.

(2) Functional thinking

Thinking 1: The message synchronization function is comprehensive in details. In the setting options of incoming call reminder function, users can set functions such as delayed reminder and not reminding strange numbers; For the APP notification reminder, the user can choose to remind only when the mobile phone turns off the screen;

Thinking 2: The message synchronization function cooperates with do not disturb mode to improve the intelligence of the bracelet. Do not disturb mode will automatically help the user turn on the do not disturb mode when the user goes to sleep, so as not to synchronize the mobile phone messages and avoid disturbing the user’s sleep;

Thinking 3: For the setting of APP reminder function, it will be more troublesome to slide up and down to find the specified application because there are many mobile phone applications. It is suggested to add a search box or arrange the application order according to the user’s usage time.

(1) Function description

On the premise of keeping the bracelet connected to the APP, you can call out Xiao Ai by swiping the screen right. Limited by the speaker, Xiaoai students will not respond to the instructions by voice, but by text on the screen. Users can command Xiaoai students to inquire about the weather, record sports data, measure heart rate, etc. by voice, and Xiaoai students can also link with Mijia’s smart home to intelligently control the smart home switch.

(2) Functional thinking

Thinking 1: The screen of the bracelet is small, and the user’s operating space is limited. Xiaoai students provide users with a more convenient way to use by voice interaction. At the same time, the smart home is controlled by the bracelet, which not only builds the integrity of Xiaomi’s ecological closed loop, but also builds a core barrier for mi band.

Thinking 2: At present, when Xiao Ai encounters an unrecognized instruction, the user needs to manually return to the main page. It is suggested that when Xiao Ai meets an unrecognized instruction, he should inform it in words on the screen and then return to the main page automatically. Because of the limited recognition accuracy of the bracelet, users often lose patience when they give instructions for many times and fail to get a correct reply. Manual operation by themselves and automatic exit from the main page can simplify the user’s operation path.

(1) Function description

There are two ways for users to set the dial background, which can be set directly on the bracelet or through Xiaomi Sports APP. When setting the dial background on the mi band, users need to slide up and down to view different themes. Touching the dial can complete the setting of favorite themes, and then automatically return to the home page after the theme setting is completed.

The number of dial backgrounds provided on the bracelet is small, in contrast, the dial background in Xiaomi Sports APP is richer and more personalized. When users set the dial background through Xiaomi Sports APP, they can choose an online dial or a custom dial, in which the online dial contains many popular images such as Watch Pioneer, Qin Shimingyue, and My Emperor Wan Shui. The custom dial allows users to upload photo album pictures and set the background.

(2) Functional thinking

Thinking 1: Because dial wearers have different ages, genders and preferences, the function of supporting users to customize the dial background is convenient for users to set their favorite dial themes, which improves the fun and user experience of wearing bracelets. At present, the background of online dial is obtained free of charge. In the future, it may be considered to increase the theme background form and acquisition threshold. For example, 10,000+steps per day can unlock the new dynamic background and integrate different functions more naturally.

Thinking 2: Set the dial background on the bracelet to guide the user to browse the theme up and down. The "↑↓" arrow is a two-dimensional plane static, which is easy to give the user the illusion that he can click, and there is a mistake when browsing the theme. It is suggested to change the arrow to a dynamic or more three-dimensional effect to guide the user’s operation more clearly.

This part will analyze the operation strategy of Xiaomi Sports APP from two aspects: promoting retention and realizing. Because the number of new users of Xiaomi Sports APP strongly depends on the number of users in mi band, we will not analyze the strategy of pulling new users.

(1) launch the community plate.

Xiaomi Sports APP provides a community module to carry its content and social functions. Its core functions include community popular content recommendation, content display of people concerned, recommendation of hot topics, recommendation and release of hot people.

For Xiaomi Sports APP, the community section allows users to interact and communicate, meet users’ sense of belonging and social needs, and promote users to use products in more fragmented scenes.

At present, the community sector is still in the early stage of functional construction, and there is no clear and mature strategy for content integration, recommendation mechanism and content distribution.

(2) material incentives for popular activities

According to the season and current hot spots, popular activities with different themes are launched. Most of the activities are to encourage users to wear mi band+use Xiaomi Sports APP, and they can obtain shopping vouchers and electronic product lottery qualifications by continuously completing the specified goals in one cycle.

From the user’s point of view, this activity promotes the user’s enthusiasm for sports, helps users build goals and develop good sports habits; From the product point of view, the continuous activity form of punching cards has a significant effect on periodically improving user activity and retention, and it can also be used as an experiment before some functions go online to assist decision-making.

(3) medal building growth system

Xiaomi Sports encourages users to participate in activities and exercise more actively by setting different kinds and levels of medals, thereby enhancing user activity, increasing the cost of leaving and keeping it. As shown in the figure, there are a large number of medals, and each medal has a different pattern and name, which maximizes the collection desire and sense of accomplishment brought by the visual differences of medals to users.

For users, medals can’t be exchanged for material rewards like points, so consider giving medals exposure in more scenes to satisfy users’ show-off psychology.

At present, the main exposure exit of medals is personal homepage. It is suggested to add the medal wall function after the user’s nickname in the "community" function module, so that users can choose the medals they want others to see. This can keep users fresh about medals and increase the motivation to collect medals.

(1) Course payment

Under the "Courses" tab, there are many kinds of sports-related courses such as fitness, running, aerobics and yoga, including paid and free courses.

Course navigation at the top of the first screen of the page can help users find the target course faster, and courses with different themes are also launched at the bottom of the first screen. For users who have fragmented time to exercise, users who are unwilling to pay high fees for fitness instructors, and users who love sports but lack professional knowledge, the course area can guide them to exercise anytime and anywhere at a lower price.

Course payment, as the main service of the realization function of Xiaomi Sports APP, is slightly rough in many functional details. The details are as follows:

1) The screening conditions of sports course navigation lack "free" and "paid" conditions. Many users just came to the course area, preferring free courses and having lower willingness to pay. At this time, if users can quickly find high-quality free courses, they can improve their goodwill and promote the payment behavior;

2) The labels of physical education courses are not updated in time. It is known in the shivering late autumn that the course label still has a label that is out of season, such as "Summer Slimming Raiders".

3) Try to see that there is no pause button on the course playing page. If users want to pause, they can only exit and re-enter. Considering that this function aims to encourage users to do it in one go during the exercise, don’t give up halfway, but it will greatly reduce the experience of users watching the course.

(2) Health services

At present, the realization mode of health service is still in the initial stage, including improving insomnia, reducing fat and genetic testing services. Users can enjoy online or online+offline services after paying.

The types and quantity of services are limited, but in recent years, Huami has accumulated a large number of users’ life and health data, which provides a barrier for its follow-up health services. At the same time, with the arrival of 5G and the maturity of AI technology, health service will become the main force point of its realization mode.

The release date of Glory Bracelet 5 is only one month away from that of mi band 4, and their prices and user portraits are similar, so we choose Glory Bracelet 5 as a competing product for analysis. The functional pairs of the two are shown in the following table:

Compared with Glory Bracelet 5, mi band 4 has the following advantages:

  1. The battery life can reach 20 days, which enriches functions and continues mi band’s excellent battery life;
  2. Built-in voice assistant of Xiaoai classmate makes voice control more convenient;
  3. Control the smart home. After the bracelet is connected to the IoT device, the smart home can be remotely controlled by voice.

At the same time, mi band 4 also has some problems to be improved:

  1. Detachable charging brings great inconvenience, which will lead to problems such as loose wrist strap and ash entry for a long time;
  2. The related health management functions are not perfect, lacking the functions of blood oxygen monitoring and sleep eye movement monitoring.

(1) Advantages

  1. Long endurance and high cost performance have accumulated a large number of users for mi band.
  2. The new entrance of smart home has richer application scenarios to help users connect multiple services in the Xiaomi ecosystem in series.

(2) disadvantages

In order to maintain high cost performance, there is often a shortage problem, and there is a potential risk of losing users.

(3) Opportunities

  1. China government’s concern for health has injected impetus into the smart wear industry.
  2. The arrival of 5G provides technical support for the development of smart bracelets in sports, medical care, health and other industries.
  3. People’s consumption level is constantly improving, consumers’ health awareness is also constantly improving, and there are still a large number of users in the market who have potential demand for mobile phones.

(4) threats

  1. In the next five years, faced with the competition of smart wearable devices such as smart watches and smart headphones, the growth rate of the smart bracelet market will slow down;
  2. The homogenization of bracelets is serious and the data measurement is not accurate enough. How to improve data accuracy while maintaining cost performance and launch a bracelet with subversive and innovative functions is an urgent problem to be solved at present.
  1. You can’t control the music during running.Most users have the habit of listening to songs while running. However, at present, the functions of running record and controlling music playback cannot be parallel, which affects the song-cutting behavior of users during running. Consider adding the background running function of sports record.
  2. There is no pause button on the sports course playing page., if the user wants to pause, smart exit and re-enter. Course is one of the ways to realize Xiaomi’s movement. The lack of "pause" button has seriously affected the enthusiasm of users to learn the course. It is suggested to increase the pause function as soon as possible.
  3. The functional modules are fragmented and lack of integration.For example, there is no stretching course guidance before and after running, there is a lack of display of user medals in community UGC content, and there are no thresholds such as payment and sports standards for dial theme acquisition. It is suggested that sports records, courses, growth system, community, dial setting and other functions should be infiltrated with each other to form a mutually reinforcing effect.
  4. Sleep monitoring only supports at night., unable to detect the user’s nap data, the lack of this function will lead to imperfect data records, which may have a certain impact on the subsequent in-depth health field.

China has become one of the 5G "first echelon" mobile phones, which will be available in the first half of next year.

  At the 2018 Mobile World Congress (MWC) in Barcelona, Spain, 5G has become one of the hottest keywords. Compared with the concept, framework and possibility of 5G discussed more in the past, a number of important breakthrough China 5G products were unveiled in this year’s conference, and some mature technologies and application scenarios were also displayed in the exhibition, which started the countdown to welcome the arrival of the 5G era.

  dynamic

  Huawei released the first 5G commercial chip and terminal.

  As one of the largest annual exhibitions in the global communication field, there are many voices and highlights from China enterprises at this World Mobile Communications Conference. During the exhibition, Huawei released the first 5G commercial chip and terminal based on 3GPP standard, and ZTE and other companies also demonstrated their respective scientific and technological strength. According to the analysis, these new products mean that China enterprises are taking the lead in the field of 5G.

  pay close attention

  5G smartphones will be available in the first half of next year.

  In the terminal exhibition area of this conference, a conceptual mobile phone with ultra-high speed of 1.2Gbps also attracted a lot of attention. It is understood that this smart phone product, which is praised as "quasi-5G" or "pre-5G" by the industry, takes less than two seconds to download a high-definition movie.

  It is worth mentioning that during the current Mobile World Congress, China Mobile announced that it would jointly launch the "5G Terminal Pioneer Program" with 20 terminal industry partners around the world. The plan aims to launch the first batch of 5G terminals as soon as possible in the early stage of the industry, promote multi-party cooperation and jointly establish a mature 5G terminal industry ecology.

  According to reports, the plan has been widely responded and actively supported by the terminal industry, including 6 mainstream chip companies such as Qualcomm, Huawei, MediaTek, Ziguang Zhanrui, Intel and Samsung, and 10 mainstream terminal companies such as Huawei, OPPO, vivo, Xiaomi and Samsung.

  China Mobile expects that all parties will make concerted efforts to launch the first batch of 5G chips that meet the needs of operators before the end of 2018, and release the first batch of 5G pre-commercial terminals, including data terminals and smart phones, in the first half of 2019. The analysis believes that this also means that many brands of 5G mobile phones are expected to be available in the first half of next year.

  prospect

  There are still about two years before the real outbreak of 5 G.

  According to the plan of the Ministry of Industry and Information Technology, the three major domestic operators are expected to realize the scale commercialization of the fifth generation communication technology in 2020. According to the data, since 2013, China has taken the lead in launching the 5G test and R&D process. At present, China’s 5G commercialization process has been promoted in an orderly manner, and technology research and development testing has officially entered the third stage this year. The 5G field tests of the three major operators have been started one after another, and the pilot construction has been stepped up.

  At the same time, a number of recent developments that have emerged since the second half of last year show that 5G promotion is accelerating. Industry analysts believe that although there are still about two years before the real outbreak of 5G on the commercial timetable, the wrestling of the 5G industrial chain has been fully rolled out. The analysis also pointed out that with the commercialization process of 5G network, it will drive the development of applications such as car networking, Internet of Things, drones and cloud computing, which means that 5G will not only become a new round of development opportunities for the global communication industry, but also create opportunities for the rise of various emerging information technologies.

  The 5G economic report released by IHS, a market research organization, predicts that by 2035, 5G will create 12.3 trillion US dollars in global economic output and create 22 million jobs. Among them, China will have 9.5 million jobs, ranking first in the world, far exceeding the United States (3.4 million).

  The White Paper on the Economic and Social Impact of 5G issued by relevant institutions in China also pointed out that 5G, as a general-purpose technology, will open up a new era of mobile communication development, accelerate the process of economic and social digital transformation, and push the development of China’s digital economy to a new level. The white paper predicts that the direct output and indirect output driven by 5G will reach 6.3 trillion yuan and 10.6 trillion yuan respectively in 2030. In terms of direct output, according to the official commercialization of 5G in 2020, it is estimated that it will drive about 484 billion yuan of direct output in that year, and it will increase to 3.3 trillion yuan and 6.3 trillion yuan in 2025 and 2030 respectively, with a compound annual growth rate of 29% in the past ten years. In terms of indirect output, in 2020, 2025 and 2030, 5G will drive 1.2 trillion yuan, 6.3 trillion yuan and 10.6 trillion yuan respectively, with a compound annual growth rate of 24%.

  News memory

  5G can finish a 1080P movie in a few seconds.

  What is 5G? The relevant technical specifications of the International Telecommunication Union (ITU) have identified eight key capability indicators for 5G. According to reports, the peak rate of 5G in the future can reach 20Gbps. Other capability indicators include user experience data rate of 100Mbps, delay of 1 millisecond, connection density of 1 million devices per square kilometer, and traffic density of 10Mbps per square meter.

  "Compared with the current mainstream 4G communication, 5G brings the most intuitive benefits to users. In addition to improving the quality of calls, that is the transmission rate." Relevant professionals pointed out that the speed of 5G network can reach the level of Gbps or even tens of Gbps, which means that a movie in 1080P format can be downloaded in a few seconds. In addition, 5G communication also has the characteristics of low power consumption and high access, and has become an important foundation for the development of the Internet of Things.

  "For enterprises, 5G will create value for many fields, such as automobile transportation, energy/utility monitoring, security, finance, medical health, industry and agriculture, especially for large-scale and key application fields that require low latency. For consumers, the highlights of 5G services will be concentrated in two aspects: ultra-high-definition video applications and AR/VR applications. " According to the relevant report of GSMA, it is estimated that by 2025, 5G networks will be commercialized in 111 countries and regions around the world. After the early deployment, the 5G network will provide enhanced mobile broadband services with high speed, low delay, reliability and security.

  However, professionals also pointed out that in order to enjoy the convenience brought by 5G communication, consumers also need a terminal that supports it. At present, mobile phones in the hands of ordinary domestic users are not yet supported. "The arrival of the 5G era is bound to set off a new round of replacement boom." The above-mentioned person said.

How many times does Hua Xizi go crazy from "high-end"?

one

People always try to show what they don’t have.

For example, high end.

People will always avoid their biggest problems.

For example, it is not worth it.

2

In the past two weeks, I didn’t write Hua Xizi, because it was clear.A brand that relies on marketing at birth, a brand whose marketing thinking is dominated by traffic has been completely solidified in its blood. When it comes to public relations, it should be blind and there is no room for operation.

People eat meat every meal, even if I say eat something to clear my stomach, whether I can listen to it is one thing, and whether it works is another. It honked before it was finished. Whose is it?

At that time, the four words in my mind were: this is the end of the story.

Reality tells me that I have never seen the world again. What do you mean "so far"? I didn’t get there until last week. The drama was yesterday!

three

A brand that thought about it for more than 10 days and decided to take the "high-end" route prepared a pile of materials. As soon as the words were finished, the natural flow was sent to the list, and the related word of "explosion" was "crazy". People send the nickname "Huaxi Crazy".

This is a plot in a pure literary satire novel, which can’t be made up by online texts.

Several public relations groups in our family also exploded immediately. Let me analyze.

I am overwhelmed. I won’t. What skill can I have to analyze what strategy this is using?

Later, a classmate helped me out:

Well, I really don’t want to think about who came up with it, how and why. A collection of funny comments and all kinds of rough god judgments have been posted outside.

I said the most direct operation problem.

four

Huaxi Zi’s complete set of materials is a 29-word release with a picture, plus 11 replies for control and evaluation. It’s really a rice circle. You have to call your senior first.

The push time is set at 16:53, which is the wave of migrant workers coming off work at night.

Benefits: There is ample space for operation, people who eat melons have time to see it, and the media has time to follow up.

Disadvantages: There is plenty of time to scold you.

five

Before disassembling the materials, let’s sum up the core.

Many people say that the problem of Hua Xizi is "expensive or not".

Actually, it is not.

We have been in the market economy for so many years, including cosmetics such as eyebrow pencil, which are completely the daily consumer goods with the least strategic significance. "Expensive or not" is completely a matter of automatic market adjustment.

What Hua Xizi can’t explain is: why is it expensive?

That is, is it worth it?

six

Say I don’t know if Hua Xizi is aware of it, but I’m sure I’m not happy after listening to it:Hua Xizi’s brand power is very weak.

The vernacular explanation of brand power is why this thing is willing to let people spend this money.

Luxury goods are expensive, which means "spending a lot of money to buy things that are not worth the money". "Yes" means that the brand itself knows, the buyers know, and the people who don’t buy know.

If everyone clearly knew and accepted that the money spent was mainly spent on packaging design and channel sharing, public opinion would not be like this.

I’ve been saying this for about five years:Live broadcast can’t increase brand power.

Not only Hua Xizi, but also a large number of such brands have a common feature: lack of brand power. We know 79 items, and today we sold 59 items, which is a good deal. However, why 79, why 59 support, no.

seven

To put it another way, marketing words and brand accumulation are completely different.

A lot of good-looking TVC and the SLOGAN of the East can’t protect the brand.

The beauty industry can be seen everywhere. The words used in most marketing scenes can’t stand scrutiny at all, have no hidden logic, are self-contradictory, and can’t form the integration of brand tonality. It is a nice word that users can easily save money after listening.

eight

Personally, I don’t think domestic products must take the path of "cheap big bowl"

In the past few years, the Yan value economy and various "beautiful little wastes" have emerged one after another, and some people will buy them.

In fact, you can go any way.The key is to have a cognitive consensus between the brand and the public.

Huaxizi sells for 79 yuan, but Huaxizi thinks it’s high-end so it’s not expensive. Li Jiaqi knows how the money is divided, so it’s not expensive. When users look at 0.07 grams, it’s definitely expensive.

Everyone is not in the same position and angle, which is the contradiction.

nine

Hua Xizi didn’t want to face the problem directly, and he didn’t want to solve it at all, which led to all the published contents talking to himself.

The behavior shown can’t match what you say.

Let’s start with Lord Weibo.

Lord Weibo’s brand tone is high-end, and every place in the whole operation has nothing to do with "high-end".

No high-end brand will describe itself as high-end by writing the word "high-end". No high-end brands will make official comments.

Lord Weibo’s pictures highlight a "good attitude". The implied position of a good attitude is clear: I am right, I am wronged, and I will not change. This is obviously on the opposite side of the public.

Besides, how can a high-end brand with a good attitude fill up its comments first?

10

In the absence of any keyword guidance, both people in the industry and the public have clearly perceived the brand tonality revealed by this content:Crazy.

It is very unlikely that Hua Xizi will want to reverse the brand tonality later.

"Deciding to spend Xizi’s life" in the picture, a crazy life?

11

In addition to the lottery information, the first article of this Weibo review is about public welfare.

Doing public welfare is a good thing, but it needs others to praise it.

It is worthless for the official CUE to do public welfare by itself.

In the case of being scolded, using public welfare to block the loophole shows that this public welfare has been done with a purpose. Corresponding to "Put All Your Eggs", Eric Wang turns to worship Buddha after killing people.

12

The second is the 20w+ product experience officer.

Hey, what’s the use of emphasizing the process when the output results are not recognized?

With good results, the process of hard work is meaningful, such as Huawei.

Without a good result, the more difficult the process is, it may mean that the worse you are, the less suitable you are.

These words are full of self-emotion and self-emotion.Tell the rice circle, can’t you see how hard my brother works? It’s the same as a dime.

Hold a little, can’t see.

13

The third article still shouts "the mission of each generation has its own generation", trying to cover up its own shortcomings with grand propositions.

The cognition revealed in these words is extremely superficial: who is next to you and who is opposite you is a high-end performance. On the contrary, it has nothing to do with consumers or products. Will this expression resonate and be understood?

A high-end brand, which claims to be aiming to go global, behaves like a red carpet.

14

The fourth question is, does anyone really use gram weight to measure the value of eyebrow pencil?

Oh, my god Communicate with consumers by educating them. N brands have learned a bloody lesson before this mistake.

Hua Xizi has to upgrade to the ironic sentence of "there is really someone", which obviously looks down on people.

This is the one with the highest response. The following netizens are also educating the brand with more than 13,000 responses.

15

Article 5: Continue to feel sorry for your product manager.

After this paragraph is sent, you are still the only one who loves you dearly.

16

Article 6 is amazing. We sold all CCTV and Xinhua News Agency and pulled them out to stop bullets.

There is a message in the reply that "CCTV wants to call the police".

This is a naked sale of the media. People support you, you push them out backhand and put them on the bar.

I am CCTV or Xinhua News Agency, and I must have cursed "mental derangement" in my heart.

This kind of industry taboo and very unkind operation also exists in the circle of friends of management. This is not just a question of whether the brand is high or not, but it is very low-level for people to do so.

Who dares to write to him, who dares to send him something, and who dares to give him awards in the serious media.

17

Seventh, it is very, very low-level to pull children out to cushion their backs.

With children’s smiling faces …

18

Article 8 interpret the problem as being excluded and competing against me.

It is another problem that many brands can’t persuade.

There is a saying, isn’t improving service and logistics what a brand should do? Take what the brand should do, make an exchange with consumers, and praise you for not being corrupt is a level requirement.

19

If you read article 9,You will find that Hua Xizi has pulled out all the "good things" he has done before and walked it again.

Well, what can I say? It’s really not on the table.

20

Article 10 mentions the national standard. Doesn’t the standard mean that it must be met?

Finally, I CUE myself to spend Western currency.

This is a malicious stalk that you should completely avoid. Others say you are a little rabbit, you can call me a little rabbit; People call you a traitor, can you call me a traitor?

21

Article 11 When it comes to R&D sites and R&D personnel, it is better to say R&D results. What is the high technology of eyebrow pencil?

Playing crazy can’t solve the fundamental problem. Besides, it’s really crazy.

This article comes from WeChat WeChat official account:In public relations (id: justprit), author: Yao Suxin

Xiaomi automobile SU7 appeared in Lei Jun: impossible 99,000 yuan.

On December 28th, 2023, Xiaomi Automobile Technology Conference was held in Beijing. The first product Xiaomi SU7 was also unveiled and positioned as a C-class high-performance eco-technology car.

Lei Jun, founder, chairman and CEO of Xiaomi Group, said that Xiaomi Automobile is a major leap of Xiaomi, a leap from mobile phones and AIoT to automobiles, a leap of long-term investment and deep cultivation of the underlying core technologies, and an adult leap of Xiaomi’s modern industrial intelligent manufacturing capability. It is also a key leap in the complete closed loop of "the whole ecology of people, cars and homes".

Lei Jun said that through 15 to 20 years of hard work, Xiaomi Automobile will become the top five automobile manufacturers in the world.

It has been 1003 days since Xiaomi Group announced that it will build a car. On March 30, 2021, with a paper announcement, Xiaomi officially announced to build a car and enter the smart electric car track, investing 10 billion US dollars in the next 10 years. At the spring new product launch conference of Xiaomi "Endless Life" held on the same day, Lei Jun said that he would lead the team, calling it the last major entrepreneurial project in his life and shouting "Fight for Xiaomi Automobile".

After that, the news was intermittent.

In September 2021, Xiaomi Automobile Company was officially registered, and then its core members were announced, including CFO Lin Shiwei, co-founder Liu De, co-founder Hong Feng and SVP Lu Weibing. In November 2021, Xiaomi Automobile announced that it will settle in Beijing Economic Development Zone, including headquarters, sales headquarters and R&D headquarters, and will build a vehicle factory with an annual production capacity of 300,000 vehicles in two phases; In April 2022, the first phase of Xiaomi Automobile Factory started construction; In August 2022, the video of Xiaomi’s autonomous driving technology was released …

When the time came to December 25th, 2023, Xiaomi announced that it would build a car for 1,000 days. Lei Jun officially announced in Weibo that the Xiaomi Automobile Technology Conference would be held at 2pm on December 28th, and said, "This time, only technology will be issued, and no products will be issued." Then Xiaomi released posters and paid tribute to BYD, Weilai, Tucki, Huawei and other enterprises.

At this conference, Xiaomi introduced the progress of five core technologies of automobiles, including electric drive, battery, large die casting, intelligent driving, intelligent cockpit and other key areas.

In the field of industrial hard technology, Xiaomi independently developed and produced the motor HyperEngine V8s, with a rotating speed of 27200rpm, and the pre-developed next-generation millet motor successfully broke through 35000rpm; in the laboratory. Xiaomi self-developed CTB integrated battery technology, and adopted the battery cell inversion technology to achieve 77.8% battery integration efficiency.

In addition, Xiaomi independently researched "9100t super large die-casting cluster" and self-researched die-casting alloy material "Titan alloy", and realized self-research from materials and equipment cluster system to finished castings.

In the field of intelligent soft technology, based on Xiaomi 澎湃 OS, Xiaomi intelligent cockpit realizes the bottom reconstruction, evolves for the car, and creates an advanced intelligent mobile space; In the field of intelligent driving, Xiaomi released three technologies: adaptive zoom BEV technology, large road model and super-resolution network technology.

"What we want to build is not a mediocre car, but a dream cars comparable to Porsche and Tesla." At the press conference, Lei Jun shared Xiaomi’s goal of building a car: to make a good-looking, easy-to-open, comfortable and safe mobile smart space.

From the beginning of research and development, Xiaomi’s first product, SU7, has built an advanced mobile smart space based on the concept of science and technology × ecology, and exerted its strength in high performance, ecological technology and mobile smart space experience.

In the extreme technology and advanced driving experience, with a series of scientific and technological innovations such as self-developed motor HyperEngine, CTB integrated battery technology, and body structure based on 9100t die casting technology, Xiaomi SU7 Max accelerates to 2.78 seconds at zero speed and the maximum speed can reach 265 km/h..

In the advanced experience of the mobile smart space, the five characteristics of Xiaomi 澎湃 OS (bottom reconfiguration, cross-end intelligent, active intelligence, global security, and open ecology) get on the bus collectively. The interactive experience of Xiaomi smart cockpit is the same as that of the mobile phone tablet, and the car system starts quickly in 1.49 seconds. At the same time, it also has a cross-end interconnection experience between mobile phones and cars.

More importantly, Xiaomi SU7 has achieved three major ecological empowerment, integrating Xiaomi application ecology, hardware ecology and Xiaomi CarIoT ecology open to third parties.

Among them, the car system is deeply adapted to mainstream car applications, the Xiaomi tablet 5000+ application will be gradually adapted, and the mobile phone application can also be pinned to the car; In terms of hardware ecology, 1000+ meters of home devices have been supported to get on the bus without induction, and the Pin point expansion interface is reserved in the car to support plug and play of devices …

As for the price of SU7, Lei Jun said that it can’t be as low as some people expected, and it will be a bit expensive. "It’s impossible to pay 99,000 yuan, and 149,000 yuan is needless to say."

What are the advantages of Huawei’s intelligent driving system?

With a picture of history, Huawei’s smart driving ushered in a new chapter in the country.

With the progress of science and technology, major car companies have accelerated the development of smart cars. Intelligent driving function is gradually becoming a key indicator to measure whether a vehicle is advanced or not. It is worth noting that Huawei has released a nationwide urban advanced intelligent driving scheme that does not rely on high-precision maps, and also announced that its intelligent driving technology covers 243 cities. In this context, the whole industry seems to be shifting rapidly in the direction of driving without maps.

The past "Kaesong" competition has been upgraded to a nationwide map-free challenge. But what is the driving force that prompted these car companies to decide to join this seemingly mysterious uncharted field? Is there really an essential difference between graphs and graphs?

When computing power overcomes financial power-driving a new era without plans and wisdom

Intelligent driving with map and intelligent driving without map represent two very different technical paths. Traditional intelligent driving with maps relies on high-precision maps, which record road information to centimeter level in detail, including lane line position, type, width, slope, curvature, traffic signs, signal lights and obstacles. Simply put, intelligent driving with a map seems to let the vehicle move along a preset and accurate trajectory. However, this method requires extremely high capital investment.

You may not know that the process of making high-precision maps is very complicated and arduous. Each surveying and mapping vehicle can only complete about 100 kilometers of data collection every day, and the cost per kilometer can reach several thousand yuan. With the rapid infrastructure construction in China, even the newly mapped roads may be unrecognizable after a week. In addition, the change of map limits the intelligent driving ability of car companies, and it is necessary to constantly update the map data to maintain the effectiveness of the system.

On the contrary, intelligent driving without map abandons the dependence on high-precision maps, making it possible for vehicles to drive freely in a wider range. This way requires vehicles to have stronger perception, more advanced algorithms and greater computing power, which puts forward higher requirements for their own intelligent driving system.

How Huawei Leads the Industry Again —— Intelligent Driving without Map in China

1. Clear vision and profound insight-lidar is still king.

In the technical field of intelligent driving without map, the mainstream is divided into lidar school and pure vision school. At present, advanced intelligent driving mainly depends on lidar, and its high-performance lidar with multi-threading, high-frequency scanning and long-distance detection means clearer monitoring ability and faster response speed.

The actual rescue incident and online celebrity dodge video directly prove the strength of high-performance lidar. In the bad environment such as night or backlight, this kind of components with high perception ability also shows its advantages, because they can provide a lot of accurate information, which puts forward higher requirements for computing power and algorithm. Therefore, the smart driving model equipped with lidar is not only more expensive, but also the strength of software research and development can not be ignored.

On the other hand, the vision intelligent driving scheme led by DJI and Baidu relies on 2D video content, which is relatively low in computational power and algorithm requirements. Of course, in the actual test, the visual system did not show too many bright spots, indicating that there are still differences between the two in practical experience. Moreover, it is an indisputable fact that the camera is easily affected by the weather and strong light.

Huawei has demonstrated excellent performance in system hardware, adopting multi-sensor fusion sensing solutions such as lidar, millimeter wave radar, ultrasonic radar and visual sensing camera. Lidar can quickly and accurately capture the three-dimensional structural information of the surrounding environment, and is not affected by environmental light. Combined with millimeter wave radar, ultrasonic radar detection and camera perception, it provides farther and more accurate three-dimensional environmental information for vehicles.

The fusion sensing system independently developed by Huawei deeply integrates various sensors to ensure smooth data communication and efficient operation of the system.

2. From branches to urban obstacles, GOD network bid farewell to the "white list"

In order to control the vehicle accurately, intelligent driving system needs to fully understand the external environment of the vehicle. BEV+ white list technology commonly used in the past identifies the detected objects, such as pedestrians and electric vehicles, through the white list input in advance. However, this technology has an obvious disadvantage-it needs the system to constantly learn different obstacle types to update the white list. If you encounter rare irregular obstacles, the system may misjudge, leading to hesitation and dangerous driving behavior.

Huawei’s GOD2.0 network (Universal Obstacle Detection) overcomes this problem. Like "My World" game, the GOD network regards all detected objects as 3D blocks. In this way, the system can easily judge obstacles on the route, including pedestrians, cars and so on. For abnormal obstacles, such as cartons, fallen trees, roadblocks, etc., the system can also identify them efficiently. In the GOD2.0 network, any object occupying space is a potential obstacle and needs to be avoided. This breaks the restriction of relying on the white list.

3. Not only do you know things better, but RCR technology is the key to no map.

In addition to the recognition of "things" by GOD2.0 technology, Huawei’s intelligent driving must also make the system recognize "roads". Intelligent driving without map is very important for the accurate perception of roads, especially at complex intersections, narrow country roads or sections without obvious signs and markings, which poses a higher challenge to the processing capacity of intelligent driving system.

Huawei Intelligent Driving combines ordinary navigation maps and RCR network reasoning to construct a large-area road topology map, which is equivalent to the size of 2.5 football fields. This is equivalent to the vehicle drawing an exclusive map for its own driving route, so that the intelligent driving system can easily analyze the realistic road information without relying on high-precision maps.

4. Massive data need to be processed quickly, and MDC chip drives L5-level assisted driving.

With the ability of perception and understanding of "things" and "roads", the next step is to summarize, analyze and calculate this information, and finally control the vehicle intelligently. The processing of massive sensor data is not a small challenge, especially in a very short time. Therefore, strong computing power is another requirement of intelligent driving.

Huawei’s self-developed MDC series chips have higher processing capability than Orin in NVIDIA, and can efficiently process information from various sensors. At the same time, Huawei’s intelligent driving system avoids blind "stacking", and the existing MDC hardware platform has enough computing power to support L3-to-L3 autopilot assistance functions without increasing unnecessary car purchase costs.

5. Covering the global road network in five days, Huawei BU Computing Center takes the lead.

After getting rid of the shackles of high-precision maps, gaining rich driving experience has become the next goal. Early intelligent driving systems mostly rely on the test data of real vehicles on the road. At present, AI modeling and cloud "running map" have become mainstream practices, and Huawei has once again taken the lead in this field.

Huawei Cloud Computing Center has the leading domestic computing power of 2.8EFLOPS, and is at the forefront of the industry. This huge cloud computing power has brought great advantages to Huawei’s intelligent driving. Using the cloud scene library built by Pangu model, the system carries out more than 12 million kilometers of simulation tests every day. Considering that the total length of global roads is about 64 million kilometers, Huawei’s system can cover every corner of the world in only 5.3 days. A large number of simulation tests have forged a real "old driver" intelligent driving system.

From the transition from a graph to a graph-free one, users finally experience the pleasure of easy travel wherever they go. Behind this is the black technology produced by the perfect combination of multiple systems.

With the help of full-stack self-developed hardware, rich data resources, unremitting pursuit of technological innovation and forward-looking technical concepts, Huawei launched the nationwide intelligent driving without maps for the first time. As consumers, we no longer need to wait for the update of high-precision maps, and we don’t have to worry about the experience of smart driving being degraded due to various problems.

This intelligent driving system makes the new energy vehicle become a really easy-to-use and safe smart car. Huawei has demonstrated its leading ability in the field of intelligent driving, which not only allows users to enjoy a comfortable and safe smart travel experience, but also sets a new standard for the whole industry.

LI was blasted for "issuing an 8-month year-end award". Insiders: Not so much on average.

Image source: LI

When it comes to year-end awards, the nerves of migrant workers will be extremely sensitive. The year-end awards offered by big factories are envied by ordinary workers, but they are far behind.

At the beginning of 2023, LI was accused that he only studied Huawei’s wolf culture in enterprise management, but didn’t see any dividend mechanism in employee rewards. But at the beginning of 2024, LI fulfilled his promise to learn from Huawei in an all-round way.

Recently, the news that "LI issued a year-end bonus of 4-8 months" and "Huawei paid out a dividend of 77 billion yuan" both rushed to Weibo for hot search, admiring a group of migrant workers for a time.

After all, in this year, the year-end "red envelopes" that can receive 1-2 months are a minority, and it is common to have none. Therefore, when Huawei and LI came out to hand out the year-end bonus in a big way, it caused widespread concern and discussion inside and outside the circle.

Regarding LI’s big year-end bonus, Li Xiang, founder and CEO of LI, said, "We can’t just learn Huawei’s process, but not Huawei’s profit distribution".

In Li Xiang’s view, if the target is exceeded in 2023, more bonuses will be given, and if the target is not achieved in 2022, less bonuses will be given, so that rewards and punishments will be clear. Only learning the advanced process, not learning the advanced benefit distribution, and unclear rewards and punishments are the biggest reasons for the inefficiency of the organization, simply tossing employees. Growth, achievement and reward are indispensable.

As an ideal learning object, Huawei lavished 77 billion yuan on year-end awards this year, benefiting at least 140,000 people, with a per capita dividend of over 500,000. What is the concept of 77 billion? The data shows that Huawei’s net profit in the first three quarters of this year was 73.056 billion yuan. In other words, Huawei is equivalent to distributing all the net profits of more than 9 months to the participating employees.

What is the ideal year-end bonus?

According to a poll of 615 people in the ideal community, among the votes that are known to give out the year-end bonus for several months, 97 people voted for the year-end bonus for more than five months. Followed by 4-5 months of voting, with 36 people. There are even people who are certified as ideal employees, saying that Ideal has issued an eight-month year-end bonus this year.

However, it is understood that people familiar with the matter in LI told Titanium Media App that the average employee is not as much as eight months, but it is definitely more than last year. It said that LI has issued a notice that employees are not allowed to disclose their year-end bonuses, including discussions among colleagues.

According to the pulse community users who are certified as ideal employees, this year’s year-end bonus in LI is generally between 4 and 8 months, with 4 months of normal performance and 8 months of better performance. Another ideal employee said that in LI’s performance appraisal standard, one M corresponds to two months, and two M’s a year is four months.

Overall, LI’s year-end bonus is more among automobile manufacturers. In contrast, traditional car companies such as GAC, SAIC and Geely generally have year-end awards of 1-2 months, and some are even lower. One user said that Geely Ningbo Research Institute only issued 5,000 year-end awards this year, while another user said that "Guangqi Honda is even worse".

This year, LI issued a large year-end bonus, which was mainly related to its outstanding performance.

In 2023, LI delivered 376,000 new cars, a year-on-year increase of 182.2%. The sales volume ranks first among the new forces, and it is also the first new force with an annual sales volume of more than 300,000 vehicles. In comparison, Weilai, which ranked second in sales volume in 2023, delivered only 160,000 vehicles, less than half of LI.

The continuous increase in sales volume, combined with factors such as the average selling price of vehicles exceeding 300,000, has boosted the performance of LI. According to the latest financial data, LI’s revenue in the third quarter (July-September) was 34.68 billion yuan, a year-on-year increase of 271.2%. Among them, the net profit reached 2.81 billion yuan, an increase of 21.8% from the previous month, and it achieved profitability for four consecutive quarters.

LI will announce its fourth quarter and annual results on February 26th. According to the forecast, LI’s revenue in the fourth quarter will reach 38.46 billion yuan to 39.38 billion yuan, up 117.9% to 123.1% year-on-year.

As of September 30th, the cumulative revenue of LI in 2023 has reached 82.12 billion yuan. If the revenue in the fourth quarter meets expectations, it means that its annual revenue will exceed 100 billion, becoming the first new force with revenue exceeding 100 billion.

Looking forward to 2024, the core goal of LI is to achieve the annual sales target of 800,000 vehicles. If successful, LI is expected to be the top luxury car brand champion in China. In contrast, BBA (Mercedes-Benz, BMW, Audi), which dominated the luxury market all the year round, sold 765,000 vehicles, 825,000 vehicles and 729,000 vehicles in China in 2023, with year-on-year growth rates of 1.7%, 4.2% and 13.5% respectively.

In order to support the annual target, LI will embark on a massive expansion of Zhang Zhilu, new product lineup and offline sales channels in 2024.

2024 is an unprecedented product year in LI, with a total of 8 new cars coming on the market, including 3 modified models and 5 brand-new models. Among them, the current models L7/L8/L9 are expected to be upgraded in March; In April, a full-extended-range vehicle, the Ideal L6, will be added. The price of this vehicle is expected to be between 200,000 and 300,000, which is considered as the key vehicle to hit the annual sales target.

In addition, LI will launch four brand-new pure electric vehicles this year, including the ideal MEGA of pure electric MPV, which has been confirmed to be launched in March, and three other brand-new pure electric vehicles to be launched in the second half of the year. By 2025, LI’s product lineup will form a layout of "1 super flagship model +5 extended-range electric vehicles +5 high-voltage pure electric vehicles".

LI’s flagship retail center has recently opened in the north, Guangzhou and Shenzhen. This is a signal that LI will expand its offline sales channels in 2024. According to the plan, LI will add more than 330 direct stores this year, aiming to expand the coverage of offline channels to all cities including fifth-tier cities. By then, the number of retail centers in LI will increase to 800, which will match the number of BBA’s sales outlets in China.

However, under the surface of the ideal aggressive sales target and expansion strategy, there are also hidden danger signals.

The first is whether the sales volume can maintain a high growth trend. In January this year, the sales of nearly 33,000 vehicles in the sector became the champion of the new forces for the first time, while LI was the runner-up with 31,000 vehicles. Since last December, when the station sold a high of 50,000 vehicles last month, LI failed to maintain the growth momentum of the previous month. Whether the new forces can regain the title in the next February is an important node for the outside world to re-evaluate LI.

In the high-pressure environment of repeated bombardments by competitors and continuous squeezing of the incremental market of the industry, it is a great pressure for LI to achieve more than 100% growth in 2024.

Secondly, can pure electric vehicles be recognized? The delayed listing of the ideal MEGA made LI, who entered the pure electric track for the first time, attract a lot of doubts. Faced with the double pressure of the layout being later than the competitors and the extremely crowded industry, it is difficult for LI to replicate the success of the extended-range track on the pure electric track.

Under the influence of various factors, LI broke out the "eight-month year-end bonus" at such a special time node, and was once again discussed with Huawei, which not only boosted morale, but also released the momentum of LI’s "far ahead" to the industry and attracted more talents to join.

For LI, which wants to expand greatly in 2024, the significance of the year-end bonus far exceeds the meaning of the "year-end bonus" itself. This wave of popularity is a good publicity for its brand exposure and reputation.

In 2024, almost everyone said, "It’s harder and more complicated". Even though there are layoffs in the industry from time to time, we still have to believe that "when God closes a door, he will definitely open a window for you." For example, enterprises represented by LI and Huawei are still expanding against the trend, speeding up their development, and awarding large amounts of year-end bonuses.

How much did the year-end awards go to the migrant workers around you?
