On July 25th, according to the exclusive revelation of a well-known blogger, the factory manager is Guan.Huawei is busy preparing for the launch of the Mate 70 series of mobile phones.This flagship work has soared to an astonishing 1.10 million points, far exceeding last year’s Mate 60 Pro Kirin 9000S and the Pura 70 series Kirin 9010 released in the first half of this year, marking another huge leap for Huawei in the field of self-developed chips.

In addition to strong hardware support, the Mate 70 series is also equipped with the HarmonyOS NEXT operating system for the first time, which is a major breakthrough for Huawei in the field of operating systems. As a truly independent operating system from Android and iOS, HarmonyOS NEXT not only has richer Hongmeng native applications, but also realizes deep optimization of third-party apps through advanced technologies such as FFRT, Ark multimedia engine, and Ark graphics engine, allowing users to enjoy a smooth experience while also feeling the unique charm of Hongmeng ecology.

In terms of ecological construction, Hongmeng native applications have entered a comprehensive sprint stage. As of now, TOP5000 applications have joined Hongmeng ecology, and 1500 + applications have been put on the shelves, covering almost all scenarios of daily use by users, meeting 99.9% of the user’s usage time. This figure not only highlights the vigorous development of Hongmeng ecology, but also provides Mate 70 series users with a richer and more diverse application choice.

However, it is worth noting that due to the adaptation problem between the HarmonyOS NEXT and Huawei’s new Kirin 5G SoC, the mass production release of the Mate 70 series may be delayed until the mid-to-late fourth quarter. Although this news has caused many consumers to regret, Huawei said that the new Kirin chip is based on an updated manufacturing platform, which brings significant improvements in process, which will bring users better performance and lower power consumption. Therefore, consumers’ patience will be worth the wait.

In terms of product design, the Huawei Mate 70 series is also full of highlights. It is revealed that the series will use an LTPO screen with a resolution of 1.5K, which is not only bright in color and delicate in the picture, but also automatically adjusts the refresh rate according to the use scene to achieve the dual enjoyment of energy saving and smoothness. At the same time, the standard 3D-TOF depth sensor camera and 50 million pixel OV50K main camera of the whole system will bring users more accurate portrait recognition and a better photo experience. In addition, the standard version of the Mate 70 will also be designed as a small-size straight-screen mobile phone to meet the unique needs of users who prefer small screens.

Overall, the Huawei Mate 70 series, with its new Kirin 5G chip, HarmonyOS NEXT operating system, and a series of innovative designs, will undoubtedly become the focus of the smartphone market this year.

　　Speaking of automobile oil, I believe everyone is familiar with it. However, familiarity does not mean that you really understand it. In fact, those things about oil are not simple!

　　Engine oil is also called lubricating oil. If the engine is compared to the heart of a car, engine oil is the blood of the car. Its main functions are lubrication impairment, cleaning, sealing and leakage prevention, rust prevention and corrosion prevention, cooling and damping.

　　At present, the market can be simply divided into mineral oil and synthetic oil according to the different base oils. Synthetic oil can be subdivided into semi-synthetic oil and fully synthetic oil. Mineral oil has the lowest price and the worst performance; Fully synthetic oil has the highest price and the best performance. Theoretically, all vehicles are suitable for fully synthetic oil, but considering the cost of vehicles and the use environment, it is generally recommended that:

　　1. Cars or SUVs with a price of more than 200,000 yuan use fully synthetic oil. Because of its excellent aging resistance, the oil change cycle can be extended to 10,000 kilometers.

　　2. Family cars with a price of 100,000-200,000 yuan are usually used for commuting, using semi-synthetic oil, and the oil change cycle is generally 7,500 kilometers.

　　3. If it is a taxi, a used car or even a vehicle with an engine overhauled, mineral oil can be used, but it should be noted that the shortest oil change cycle is within 5,000 kilometers.

　　In addition to the type of engine oil, you can also choose engine oil according to the engine oil label, of which SAE label is the most commonly used.

　　When you get a bucket of engine oil, look at the lower right corner of the bottle. This "5W-40" is the SAE label, which indicates the viscosity grade of the engine oil. Among them, "W" is the abbreviation of winter, and the number in front of W represents the fluidity of engine oil at low temperature. The smaller this number is, the better the fluidity of engine oil at low temperature, and the better the protection of engine when the vehicle is cold started. Generally speaking, there are four grades of engine oil, namely, 0w, 5w, 10w and 15w, which respectively indicate the minimum working temperature of -35℃, -30℃, -25℃ and -20℃. In other words, if you live in the northeast, choose 0w engine oil to meet your winter use. If you are in Beijing, 5w or 10w engine oil can meet your needs. In addition, the low-temperature viscosity grade is only needed for northerners to buy engine oil, but it is generally not considered in southern cities.

　　40 in "5W-40" indicates the high temperature viscosity grade of engine oil. Generally speaking, there are four high-temperature viscosity grades of engine oil: 20, 30, 40 and 60. The higher the high-temperature viscosity grade, the more viscous the engine oil will be, and the better the engine protection will be when it works at high temperature. If it is a new car or a Japanese and Korean brand car, then you should choose a thinner engine oil; If it is a large-displacement or turbocharged car, it is more suitable to choose a thicker engine oil.

　　In a word, the smaller the number before W, the better, and the bigger the number after W, the better.

Recently, the layout of Huawei in the automotive field has once again attracted market attention. The latest developments of three new cars-the extended range version, the brand-new flagship car of Jianghuai (suspected to be Zunjie) and the M8 in Wenjie have been exposed one after another, which makes people look forward to the future of Huawei in the automotive industry. Today, "Car Circle" will take stock of it for everyone!

Enjoy the S9 Extended Edition: Sales Booster

First of all, Huawei’s Enjoy S9 will launch an extended-range model in 2025. This information circle is judged based on spy photos. From the appearance, the road test is obviously enjoying S9, and the exhaust pipe at the rear of the car is evidence of its extended range identity. So what changes will the extended-range model bring to the enjoyment world S9?

This should be analyzed from the main sales models corresponding to the best-selling new power brands on the market. Both the world and the ideal are dominated by hybrid models, so before the solid-state battery technology matures and the cost comes down, hybrid is the version answer. Enjoy the pure electric version of S9. Although the 72-hour, 4800-meter volume doesn’t look scary, it’s pure electricity and its audience is very narrow. If Enjoying S9 launches an extended version, the estimated sales volume must be increased by at least zero. At present, friends who are waiting to enjoy the S9, but have endurance anxiety, can pay attention to the extended range model.

Jianghuai Zunjie: With Maibakh’s same pie wheel.

With the products built by independent brands and Huawei constantly attacking the high-end market, the spy photos of the brand-new flagship car that Jianghuai Automobile cooperated with Huawei were officially exposed, and the new car was suspected to be named Zunjie. Judging from the spy photos exposed, the new car adopts a streamlined body design, and the overall shape is atmospheric and luxurious. Together with the common pie wheels on luxury cars, it reveals a strong luxury business atmosphere.

As the brand-new flagship model of JAC, Zunjie will undoubtedly be equipped with Huawei’s latest intelligent networking technology to bring consumers a smarter and more convenient driving experience. At the same time, the new car will be built on the brand-new X6 luxury new energy platform to ensure driving comfort and stability. We will keep an eye on whether the new car is positioned higher than the enjoyment S9 or focuses on other directions.

Question M8: Lock the explosion in advance

The last car I took you to check today, the M8, is even heavier. Its latest spy photos show a high degree of completion and should not be far from the appearance. As another masterpiece of Wenjie brand, M8 continues the classic elements of Wenjie family in appearance design, and at the same time incorporates more design elements with a sense of technology and futurity. Even the laser radar adopts a built-in scheme. Personally, the watchtower scheme placed on the roof looks more advanced. For the interior, it is expected that the M8 will adopt the same design, but there may be some adjustments in the configuration, but Huawei Smart Drive is definitely the latest version.

However, what the circle brother is looking forward to is that the platform of asking the world M8 is highly likely to adopt the platform of asking the world M9, and the chassis hardware upgrade should be relatively large. The front double wishbone and rear multi-link and air suspension should not be absent, and there is almost no short board. Hardware without a short board plus Huawei’s "far ahead" software and smart driving, if its starting price is controlled in the range of 300,000-350,000 yuan, then the sales volume is worth watching.

View of "Car Circle": With the gradual deepening of Huawei’s layout in the field of new energy vehicles, the extended version of Enjoy World S9, the flagship sedan of Jianghuai Zunjie and the M8 of Wenjie have been exposed one after another, which not only shows Huawei’s powerful strength in automobile intelligence, but also brings more choices and expectations to consumers. I’m glad to see that China brand can make such progress in the high-end automobile market, and BBA’s days of lying and making money may end sooner than we expected.

Xinhua News Agency, Hong Kong, January 15th: Heading for the Future: Domestic trains set off on MTR.

　　Xinhua News Agency reporter Liang Wenjia

　　On weekdays, Kwun Tong Line trains travel between Tiaojingling and Huangpu. In the track, the train lights suddenly pass by; On the platform, passers-by are in a hurry; In the carriage, passengers can feel the fast-paced pulse of Hong Kong at any time by immersing themselves in a corner, sitting quietly or sliding their mobile phones with their heads down.

　　Some passengers have noticed the changes in the carriage: the purple theme of the ground and seats, the bright and soft round lights projected from the roof, the ring-shaped handles and armrest columns … … These all seem that the newly launched domestic train Q-Train looks different.

　　Change: Say goodbye to memory and sail for the future.

　　Q-Train, a new domestic train on the move (photo, taken in 2022). Xinhua News Agency (Photo courtesy of the interviewee)

　　There are many kinds of trains purchased by the Hong Kong Railway Company Limited (MTR), and manufacturers from different countries and regions will name them by letter codes accordingly, that is, M-Train (made by Jiamu, the British capital), Q-Train (made by CRRC Qingdao Sifang Locomotive and Rolling Stock) and C-Train (made by CNR Changchun Rail Bus) which are often mentioned by Hong Kong citizens.

　　Ye, a fan of railway traffic in Hong Kong, loves to take the subway since he was a child. He knows the subway routes and train models in Hong Kong like the back of his hand. When he heard that the new domestic train was on the line, he went to experience it for the first time and felt that all aspects of performance and ride experience were better than those of the old car.

　　Ms. Gan, a Hong Kong citizen, takes the Kwun Tong Line to work in Kowloon Bay every day. "The first time I took it, I thought I got on the wrong bus. Later, I learned that the new domestic train Q-Train had been operated on the Kwun Tong Line." She said that old trains sometimes break down, and changing to new trains will provide convenience for travel.

　　Ms Huang and her 9-year-old son are waiting at the platform of Kwun Tong Line. She said that children like to take the new train very much, and sometimes they even imitate Cantonese, Mandarin and English station announcements with excitement. She thinks that many details of the new car are very humanized, such as the dynamic line prompt on the electronic display screen and the sticker reminder on the key parts of the car.

　　The first generation of M-Trains in urban lines, which began to be put into service in 1979, has been in operation for more than forty years, and their overloaded service life means that they are on the verge of retirement.

　　Now, since the Q-Train of CRRC Qingdao Sifang Train was launched on November 27th, 2022, it will gradually replace it and start a new round of changes in Hong Kong railway traffic trains.

　　Hand in hand: let the city continue to "move forward"

　　Huang Kunyong, Director of China Mainland Business of MTR Corporation, was interviewed (photo taken on December 21st, 2022). Xinhua News Agency reporter Li Gangshe

　　Huang Kun, director of China Mainland business of MTR Corporation, is familiar with the operation of MTR at home and abroad, and mentions the origin of MTR and Q-Train.

　　"In 2015, MTR Corporation reached a contract with CRRC Qingdao Sifang Locomotive & Rolling Stock Co., Ltd. (CRRC Sifang) and invested HK$ 6 billion to purchase 93 new trains, which is also our company’s biggest investment in trains over the years!" Huang Kunyong said that this large-scale train procurement has gone through the bidding process for domestic and foreign companies, and companies from many countries and regions bid, and finally decided to cooperate with CRRC at all levels.

　　The combination of safe and reliable train performance and humanized ride experience is the key factor for MTR to consider when deciding to purchase a new batch of trains. Working hand in hand with CRRC Sifang for a win-win situation is not only an affirmation of CRRC Sifang’s manufacturing strength, but also full of confidence in the development of rail transit in the mainland.

　　Huang Kunyong said that although the teams of the two sides are separated by two places, the cooperation is particularly smooth.

　　At the same time, building a communication bridge with passengers is an important part of MTR Corporation’s continuous improvement of service quality. The design of Q-Train also adopted many suggestions from passengers, focusing on improving the layout of new trains. Compared with the first generation trains in the urban line, the new train widens the distance between the seat glass screen and the door, which is convenient for passengers to stand. From more than 20 ring handrails per car card to 64 ring handrails per car card, it is easier to hold. Passengers get on and off more smoothly, even during rush hours.

　　Huang Kunyong said with satisfaction: "Hearing the feedback from passengers, the new train is quieter and the design is much better than the previous train. For the operator, this sentence and the smile on the passenger’s face are the power to encourage us to move forward. "

　　Mission: Deliver every passenger safely and comfortably.

　　Inside the carriage of the new domestic train Q-Train (photo taken on December 21st, 2022). Xinhua News Agency reporter Li Gangshe

　　Kowloon Bay Depot is the MTR Urban Route General Factory, which provides parking, testing and maintenance services for Kwun Tong Line train sets. There are many berth tracks in the east of the depot for parking trains. A huge thick wall separates the maintenance pit in the west, and both sides of the parking space are connected with the tracks of Kwun Tong Line, and the criss-crossing tracks extend to the outside.

　　After the new train Q-Train arrived in Hong Kong, Zhao Jianpei, a train employee of Kwun Tong Line, participated in the field test before the train was officially put into service. He was very excited when he heard that he would drive the domestic train that was about to go online in advance.

　　The new train can transmit the data of key equipment during the running of the train in real time, so that engineers can monitor the train operation from a distance. Zhao Jianpei was surprised by the intelligent server equipped with Q-Train. He stepped onto a Q-Train parked on the track of the garage, entered the cockpit and began to show it to reporters.

　　"The conductor can see more information about the train operation on the train management system, and can also control different equipment in the car through the system." Zhao Jianpei pointed to the dashboard and said, "If a passenger communicates with the conductor through the emergency intercom, the conductor can remotely reset the system directly in the cab after handling the passenger’s help, so that the train can be put back into service more quickly."

　　Q-Train’s good test performance in the early stage makes the captains’ driving work handy now. Zhao Jianpei holds the accelerator. "Compared with the first generation of trains, its manual operation is a little different. We used to control the acceleration and deceleration step by step, but the speed control of new trains is uninterrupted."

　　"It’s like driving a car," Zhao Jianpei said. "The passenger experience is smoother than before, and there won’t be a lot of jitter."

　　As a conductor, every time you drive, you shoulder a responsibility. Zhao Jianpei looked out of the driver’s window and said, "Our mission is to deliver passengers to their destinations on time and provide them with better, safer and more reliable services."

Ashton Chen, a former child star, reminds many people of the clever and lovely young monk in Cyclone Boy and Young Bao Qingtian. Time flies, now he is no longer the fledgling boy, but an adult man with a happy family. In performing arts, Ashton Chen’s journey was not smooth, but he found real happiness in his life, which not only made people feel deeply, but also caused deep thoughts on his future development.

Looking back on Ashton Chen’s early years, he quickly emerged with his solid martial arts skills and unique performance style, and became an action child star in the eyes of countless audiences. However, with the change of market environment, action movies gradually lost their former popularity, and Ashton Chen’s performing arts career also fell into a bottleneck. Faced with such a challenge, he didn’t choose to give up, but worked harder to improve his skills and acting skills. He understands that only by continuous progress can he find new opportunities in the highly competitive entertainment industry.

Despite the difficulties in her career, Ashton Chen’s life is full of warmth. Recently, the media photographed his family of three with his wife and daughter many times, and the picture was warm and happy. Although Ashton Chen’s wife is an ordinary person, her appearance and temperament are not inferior to that of a star. Her plump figure and delicate facial features, coupled with the natural healthy beauty, attract people’s attention. At the same time, Ashton Chen’s daughter also inherited her parents’ good genes, so she is innocent and lovely, lively and charming.

Ashton Chen’s treasure of family life is revealed in every moment of media shooting. He may not often talk about his family in public, but every time he is photographed spending time with his family, he always has a happy smile on his face. This happiness is not accidental, but the fruit of his years of hard work. In the face of the choice between career and family, Ashton Chen’s choice makes people admire and think: Is the real success just the glory of performing arts?

Experts pointed out that Ashton Chen’s experience reflects the growth trajectory of many child stars. Many child stars who became famous in the early days are faced with the pressure of identity transformation and market changes during their growth. Some people lose themselves in the performing arts and cannot find the meaning of life. Ashton Chen’s story shows the possibility of realizing his personal value by building a happy family. He told us in his own way that the success in life does not necessarily come from the success in work, and the warmth of family is as important as companionship.

Next, people can’t help asking, what are Ashton Chen’s plans for the future performing arts? Will he continue to work hard in the field of action movies, or will he hope to transform and challenge more different types of roles? With the stability of personal life, Ashton Chen may have the opportunity to meet more good scripts and cooperation teams, which is what we hope to see.

Generally speaking, Ashton Chen’s story is not only a legend about the growth and acting career of child stars, but also a reflection of life attitude. In the changing environment, he found a suitable life path, showing maturity and responsibility. This spirit of facing challenges is exactly what we should learn.

　　When it comes to Britain, I believe many fans will think of the car culture event Goodwood Racing Festival and the famous TV program TopGear. As the birthplace of industrial civilization, Britain also has many famous car brands. However, with the passage of time, many British automobile brands are almost sold out today, and they are interpreting the British style in a brand-new way.

　　Just like Rolls-Royce and MINI are to BMW; Bentley to the public; Jaguar and Land Rover are to Tata; Lotus and Britain are to Geely … … MG (MG) is also under the management of SAIC. This British brand, which was born in 1924, has gone through 95 years of ups and downs. In 2018, under the wave of "new four modernizations", SAIC MG launched the first pure electric vehicle — — MG ZS pure electric. The first media dynamic experience of this new car was carried out in Britain, the birthplace of its brand. There are two reasons,First of all, MG ZS pure electric is based on more stringent European standards; Secondly, MG ZS pure electric will be sold to many countries and regions around the world, including ten European countries, Thailand and so on, and it is a veritable global ESUV.

PS: The official Chinese name of this new car is ZS pure electric, and the overseas version is MG EZS.

　　Before the official start of this article, let’s briefly understand the general situation of SAIC MG in the UK.

　　As an old industrial country, Britain has a very mature automobile market and consumer groups. This is also the biggest difference from China. British consumers often vote with their feet to eliminate those automobile products that should not appear here.

　　With a history of nearly 100 years, SAIC MG has a certain popularity and reputation among consumers in the UK. At present,SAIC MG sells three models of MG GS, MG3 and MG ZS in the UK.Although the total sales volume can’t compete with the first-line brands in the world at present, only MG achieved a contrarian growth of 103.76% under the overall downward trend of the British automobile market last year. It can be seen that MG has not only won a place in the British auto market, but also its development momentum is good.

　　SAIC has two design centers in Birmingham and London, which play an indispensable role in the development of ZS pure electric products. Including the research of pre-brand design language, the calibration of battery system, the research and development of European standard charging system, the road adaptability verification in Europe, the road test and the certification of pure electric vehicles in the UK, etc.

　　Why do you want a road test in Europe?

　　MG ZS pure electric vehicle is a pure electric vehicle developed for the global market, which will be exported to ten European countries including Britain, France, Germany, Norway, Belgium, Spain and other countries in the world, such as Thailand. Therefore, it should follow the REACH and E-MARK regulations of the European Union. Since the standards of EU in environmental protection, safety, energy saving and quality are higher than the national standards, it is necessary to calibrate the vehicle indicators according to the EU standards. However, the calibration of parameters is based on a large number of actual data, so data collection and testing on the actual roads in Europe is a model.facing to the worldAn indispensable link in the product development process.

　　How to conduct a road test?

　　According to the product manager of MG, there are 8 cars in the European road test at the same time. According to the market situation of each country, these 8 cars will be assigned to different countries, and a total of 1,000 hours of effective data collection will be completed. At present, the stage we are going through is the initial data collection, which will last about 3 months. The collected data will be packaged and sent to Shanghai for analysis and calibration, and then returned to Europe for the full-function test of vehicles for about 2 months. The total duration of the road test in Europe is about 4-5 months.

　　What road test projects are there?

　　There are a lot of data and items that need to be collected for the road test, and we participated in it this time.Collaborative data acquisition between ADAS camera and vehicleandMulti-road adaptability test of three-power systemTwo items. In addition, what needs to be done isAdaptability optimization of chassis system, vehicle process quality, and software optimization under various complex working conditions.Testing and data collection in other aspects.

　　●ADAS camera and vehicle collaborative data acquisition

　　In terms of active safety, European standards have stricter regulations on ADAS system’s autonomous steering, active braking and AVAS low-speed warning sound system, and vehicles under European standards must be equipped with emergency call system to rescue members in time in case of accidents. In terms of passive safety, the European standard requires all seats to be equipped with seat belts without reminding function.

　　Based on European standards, it is particularly necessary to collect the test data of ADAS system in the early stage. In the data acquisition process, British testers drive vehicles, and collect information through millimeter-wave radar at the front of the car and visual camera attached to the front windshield. For other traffic participants on the road, record the decisions made by the system and the corresponding collaborative data.

　　These collected data will be displayed in the car computer in real time and saved at the same time, so as to be taken to Shanghai for item-by-item analysis in the later stage, and the ADAS system will be optimized and debugged according to a large number of collected data.

　　● Multi-road adaptability test of three power systems

　　The other is the data collection of the three-electricity system, such as the discharge and output power of the vehicle under different road conditions, and the state of the three-electricity system under the climatic conditions in Europe. Engineers will balance and optimize the vehicle according to the collected data in order to achieve an optimal state.

　

　　　　[Aika Automotive Technology Original]

　　　　Speaking of autonomous driving, it is no longer a new concept. Since childhood, self-driving cars have appeared frequently on the big screen, and now the self-driving technology has gradually matured and stepped out of the screen, all of which are inseparable from the rapid development of science and technology. However, today, with so many manufacturers developing autonomous driving technology, do you know how many ways autonomous driving can be realized? Next, let’s explore one or two.

　　　　At the state-of-the-art level,Automatic driving can be roughly divided into two technical routes.：

　　　　The first one is based on the existing radar and sensors of the vehicle, taking ADAS (Advanced Driver Assistance Systems) as the starting point, and conducting the research on automatic driving.. This technology tends to allow vehicles to perform real-time calculations, and through the cooperation of on-board facilities such as cameras and radars, vehicles can achieve the purpose of automatic driving.

　 　The second one is based on V2V(vehicle to vehicle means information interaction between vehicles) and V2X(Vehicle to X means information interaction between vehicles and the outside world), which allows vehicles to establish information communication with the surrounding environment through mobile internet.So as to know the real-time traffic conditions and realize predictable automatic driving.

　　　　Nowadays,Both of these technologies have made great progress, but there is still a considerable gap from the real automatic driving.

1. Automatic driving based on ADAS:

　　　　Why use ADAS as the basis of autonomous driving? The reason is simple,Because ADAS already has a mass production foundation.The gradual penetration of various driver assistance systems into low-end models is the best proof.

　　　　At present, although the global market penetration rate of ADAS is not high, only about 5%, with the increase of automobile safety and intelligent demand, the market penetration rate of ADAS will be greatly improved in the future. According to the prediction of consulting firm PRNewswire, by 2020,The global ADAS penetration rate will reach 25%, and the global new car ADAS loading rate is expected to exceed 50%.Isn’t it enough that such a huge penetration base is used as the basis of autonomous driving?

　　　　Moreover, ADAS is quite mature in hardware.Bosch, NXP, Continental and other parts suppliers have already supplied tens of millions of sensors and actuators to car companies every year.Such a huge supply is enough to show that ADAS is quite reliable in hardware. In particular, NXP has recently released a powerful autopilot platform using the latest BlueBox engine.

　　　　But can you achieve automatic driving only by relying on ADAS? Of course not. Take Tesla as an example. Tesla is ahead in the field of ADAS, but it can only reach the level of second-class automatic driving. All this is due to the lack of effective support from high-precision maps.

　　　　Nowadays,High-precision maps have become a necessary and insufficient condition for autonomous driving.. According to the division of map manufacturers, high-precision maps can be roughly divided into two categories.The first is ADAS-level high-precision map.Its accuracy can reach the meter level;The second is the HAD-level high-precision map.Its accuracy can reach the centimeter level.

　　　　Because the two maps have different purposes,The ADAS level only includes basic information such as road shape and slope.And then used to cooperate with the driving assistance system of the vehicle itself to reduce driving pressure.The information collected by HAD level is more accurate, and it will record the lane type, width and surrounding environment of the road in detail.In this way, vehicles will have more detailed reference information, so on the basis of ADAS, high-precision maps have become an indispensable part.

　　　　However, due to the complexity of urban roads, it is quite difficult to collect high-precision maps in urban internal roads.It will take time to mature.

Second, autonomous driving led by the Internet of Vehicles:

　　　　After talking about the automatic driving based on ADAS, let’s talk about the automatic driving led by the Internet of Vehicles.

　　　　Simply put,The technical concept of V2V and V2X is to install a communication device on the car, and then use traffic lights, road signs, road vehicles and pedestrians as signal emission sources for real-time communication.. In this way, even if the car itself does not have the detection ability, it can know the traffic environment around it by constantly asking about the surrounding vehicles and traffic facilities, so as to realize safe automatic driving.

　　　　Compared with ADAS, V2V and V2X technologies have the greatest advantage that they can make the vehicle have foresight, instead of reacting in front of it.. Take the traffic light as an example. ADAS recognizes the image based on the camera, and judges whether the traffic light is red or green through the algorithm, while V2X can let the vehicle receive the signal 100 meters away, thus knowing the status of the traffic light, which makes the automatic driving easier.

　　　　However, this technology still needs high-precision maps as the foundation.Its biggest difficulty is that it is a very huge thing to install signal receiving devices and communication equipment on all traffic equipment, and how to unify the signal frequency is also a difficult problem for researchers.

　　BYD’s seven new cars have recently registered in the Ministry of Industry and Information Technology to declare information, which is expected to be put on the market in 2025.

　　The picture shows a panoramic view of the new look of Xinquan Town. Xinquan Town is surrounded by water on three sides. Since ancient times, it has been a waterway from western Fujian to Chaozhou and Shantou.

　　Xinhuanet Fuzhou, September 1st (Liu Mohan, Li Chen) Famous Red Holy Land — — About 30 kilometers northwest of Gutian conference site, there is a hot spring town called "Xinquan". In 1929, the Red Fourth Army was reorganized here and launched the famous "New Spring Training and Consolidation". At the end of August, the interview group of Fujian online media "Go and Change" came here to feel the red memory of this town.

　　Xinquan Town, under the jurisdiction of Liancheng County, Fujian Province, is the traffic hub of Fujian, Guangdong and Jiangxi provinces. The town has a well-developed water system and is surrounded by water on three sides. Since ancient times, it has been a waterway from western Fujian to Chaozhou and Shantou to the sea. In 1929, Mao Zedong, Zhu De and Chen Yi led the Red Fourth Army to Xinquan for three times and carried out the famous political and military training and consolidation — — Xinquan training and consolidation, drafted the programmatic document "Gutian Conference Resolution" for the construction of our party and army, leaving behind more than a dozen revolutionary sites, such as Wangyun Caoshi, the first night school for workers, peasants and women in the Central Soviet Area, Yuxi Gongci, the former site of the Revolutionary Committee of Liannan District, and Kuishan Gongci, the former site of the Guanzhuang Farmers Investigation Association.

　　Xinquan is rich in geothermal resources and is also a well-known hometown of hot springs. The seventh "Don’t molest women" in our army’s famous "three major disciplines and eight attentions" is related to this hot spring town.

　　According to reports, when the Red Fourth Army was in Xinquan, the Red Army soldiers bathed naked in the hot springs by the river after training, while the local women were still washing clothes and vegetables by the river, which was very unsightly. Mao Zedong then added the seventh item "Bathing to avoid women" to the original "Three Disciplines and Six Notices". At the same time, Chen Yi proposed Article 8 "No defecation anywhere". Later, the contents of "three major disciplines and eight points for attention" were revised, and it was fixed in a unified form on October 10, 1947. Article 7 was revised as: Do not molest women.

　　In recent years, the former training sites such as Wangyun Caoshi and Xinquan Women’s Night School have become increasingly famous in the context of red tourism. According to Zou Chongqing, director of Xinquan Training Memorial Hall, in 2015, the former site group received nearly 8,000 visitors, while from January to July this year, there were nearly 6,000 visitors.

After the establishment of Xinquan Workers and Peasants Women’s Night School in July 1929, Xinquan women were mobilized to study culture, politics and military affairs and take part in the revolution, thus setting off a vigorous women’s liberation movement.
