Super preservative helps food to keep fresh for a long time.

Microbiologists at the University of Minnesota in the United States have recently discovered a super natural preservative that can kill all kinds of bacteria and keep food for a long time at room temperature. It is reported that this preservative is called "Bisin", which is naturally produced from some harmless bacteria. This preservative can prevent meat, fish, eggs and dairy products from spoiling, and it is equally effective for opened red wine and salad dressing. The food added with this natural preservative does not even need to be put in the refrigerator, and it can be kept for several years at room temperature. However, due to the different functions of vegetables and fruits, the preservative can not keep them fresh. The researchers said that this natural preservative is better than any previous one, because it does not destroy the nutritional components of food, and no chemical components are added to food. It is just a natural component. At present, researchers have applied for a patent for Bissin in the United States. Milk, sausages and sandwiches added with Bissin are expected to be on the market within three years.

Super preservative helps food keep fresh for a long time.

?Fresh food could be made to last for years after scientists discovered a natural preservative capable of destroying a whole class of bacteria, including E.coli and listeria.

Fresh food could be made to last for years after scientists discovered a natural preservative capable of destroying a whole class of bacteria, including E.coli and listeria.

There would also be no need to refrigerate produce treated with the preservative, called, bisin, which is produced by harmless bacteria.

They say that foods like milk, sausages and sandwiches containing the agent could be on the shelves within three years.

Ready meals, opened wine and fresh salad dressing could also be safely consumed long after they were bought, say scientists.

Researchers at Minnesota University in the US discovered the substance from a culture of a harmless bacteria, Bifodobacterium longum, commonly found in the human gut.

It is the first naturally occurring agent identified that attacks so-called gram-negative bacteria such as E.coli, salmonella and listeria.

Dan Sullivan, an Irish microbiologist who now works at the university, told The Sunday Times: "It seems to be much better than anything which has gone before. It doesn’t compromise nutrient quality — we are not adding a chemical, we are adding a natural ingredient."

He and his team have patented the substance in the US.

Bisin is related to nisin, which attacks gram-positive bacteria, and is used in the manufacture of processed cheeses and meats. As such, it is generally recognised as safe and would not have to be pharmacologically tested.

It would not be able to prevent fruit and vegetables from rotting, however, as they decompose in a different way.

Further research is now ongoing, looking at exactly how good it is at stopping bacteria from growing.

Meanwhile, a British wholesaler has begun to make sandwiches with a two-week shelf life, by replacing all the oxygen in the plastic packaging with nitrogen and carbon dioxide.

Ray Boggiana, a food technologist who helped develop the range for Booker, which supplies convenience stores, said: "The science is not new. It’s all about using a protective atmosphere in the packaging."

The emotional value of the cover of millet tapping machine has to start with AE86.

Wen | Deng Cheng

Recently, the controversy over the hole-digging machine cover has made the car circle, which was quiet for a few days during the May Day holiday, lively again. People can’t help but sigh that the mass of new cars at the Shanghai Auto Show will never be as hot as the slobber.

When it comes to performance modification, Xiaomi SU7 Ultra looks murderous, and with the lap speed endorsement of Zhesai, the expected value of the hole opener cover is getting higher and higher. Coupled with Weibo forwarded by Lei Jun on March 2, it is even more hanging(quasi)The appetite of car owners has changed their orders from the original machine cover to the carbon fiber hole opener cover.

The performance modification market has always been divided into two markets: performance parts and mood parts, because track and street driving are always the scenes at both ends of the balance, so far no manufacturer can achieve a perfect balance. If we add another price factor, then the three will be a impossible trinity. No matter if the coordinate axis tilts a little to either side, it will inevitably sacrifice the other side.

In this case, if the manufacturer shows the appearance of "wanting both", then it can only do "superficial work", and the most popular modification of mood pieces in the past decade is the product of this marketing stunt.

Black lid and performance hook

I’m afraid we should start with AE86.

If the cartoon is the enlightenment of the post-80s, then the Initial D starring Jay Chou is the youth of the post-90s. In the movie, the engine limit was ignored because of Fujiwara Takumi’s eagerness to win. Finally, it ended in a blowout and lost to the Evolution of Sudo Keiichi.

However, this explosion also made Fujimoto discover the progress of his son’s strength, so he modified a 4AGE engine for him. At this point, the most classic panda black cover AE86 appeared, and both animation and movie accompanied Tuohai to win the following games.

The black cover on the family car has also become the best memory of "performance modification" in the hearts of the post-80 s and post-90 s.

With the vigorous development of the automobile industry, the substantial increase in the number of cylinders and the popularization of turbine technology, the hood has also turned from the initial flat and monotonous design to the functional evolution. For example, with the addition of electric turbine and variable cross-section turbine technology, the turbine hysteresis problem that originally needed double turbines to solve was improved. The turbine that originally needed 4,000-5,000 revolutions to start pressure quickly evolved to output surging power within 2,000 revolutions.

But the laws of physics will not disappear, the power will come faster and faster, and the accumulated heat will be more fierce. Super-runners with middle and rear engines can dissipate heat through the way of engine placement, while most performance cars with front engines can only introduce more air through the way of engine opening, so as to achieve the results of cooling and improving downforce.

Gradually, consumers’ cognition has also changed. Those things with black covers, big tails, front shovels and blades will still give people the momentum of speeding up at any time even if they keep driving at a constant speed on the road.

Impossible trinity is the same as the laws of physics.

Deeply troubled the marketing department of car companies.

Just as heat dissipation is inseparable from punching holes, car companies are also facing the problem of consumers’ growing appetite.

The demand for "mood pieces" in the domestic market is much higher than that in overseas markets. Traditions such as BBA have obvious differences in the appearance of domestic and foreign models. Various AMG, M, S-line kits emerge in an endless stream. Originally, they need additional accessories in overseas markets and will not easily appear in the appearance of entry-level models, but they have been decentralized to C200, 325i and A4 40TFSI in the domestic market.

So that in order to distinguish the real M series, BMW later changed the G8X model into a huge kidney shape, which made the most thorough distinction from the ordinary 3 series. If we follow BMW’s previous design ideas, I’m afraid fans can only distinguish the 325i dazzling night version from the real M Power through the slightly widened fender.

However, the increasingly comfortable 3 Series also proves the change of the market trend. Consumers just want a car that looks sporty, not a car that really moves when driving. After all, when stuck in the rush hour, the sore waist will let you know who is the real owner of the body.

So, the limited budget, the necessary and important market demand and the unbreakable physical laws have become the new impossible trinity of the marketing department of automobile enterprises.

The Xiaomi Marketing Way of Cheng Ye Lei Jun and Defeat Ye Lei Jun

Back to the screenshot of Weibo on March 2nd, it is not difficult to see that Lei Jun, who regarded Xiaomi as the last battle of his career, worked very hard at least before the car accident.

Auto executives actively marketing on social media can really bring high-efficiency traffic feedback, but auto products have extremely low transaction frequency and are prone to major accidents when they are not used properly. When negative news happens, executives are also the first batch of cannon fodder that will be dragged up to block the muzzle of public opinion.

How much performance improvement Xiaomi’s hole opener cover has brought, and how much reducibility it has for the exaggerated aerodynamic kit of the Newbei prototype, has always been a mystery on the SU7 Ultra.

The 911, which also has a front trunk, on its high-performance track version GT3, the space of the front trunk is cancelled, and a small area of ventilation duct is designed instead to improve heat dissipation and increase downforce.

On the other hand, the higher-order GT3RS uses extremely outrageous aerodynamic kit and opening area to achieve stronger downforce and enhance its high-speed bending performance.

It can be said that from 911, to GT3, and then to GT3RS, consumers can perceive where the money is spent, and the efforts of the engineering team in challenging the boundaries of physical laws.

Interestingly, there is also a big gap in the data of downforce between the production car and the prototype car of SU7 Ultra. The downforce publicity page of the production car not only did not show the version of the open cover, but the overall downforce was only 285kg.

The downforce of the prototype at the press conference reached a horrible 2145kg, which was seven times as much. Although the two models are consistent in dynamic performance, they are very different in aerodynamic performance.

Perhaps the performance of the prototype is too dazzling, which gives consumers too high expectations, or perhaps it is the vague statement forwarded to Weibo on March 2, and the feedback of the tapping machine cover in the market is too good. Xiaomi chose to actively downplay the performance of the tapping machine cover. After all, everyone wants to do this business of "selling performance parts and making money from mood parts".

So back to the theme of the matter, electric drive technology makes power cheaper, and the performance related to competition, whether it is aerodynamic kit, chassis tuning or braking technology, is still a peak that cannot be easily crossed. The price war has been killing today, and everyone is trying to lower the threshold of luxury cars and performance cars with lower prices.

Consumers are sure to love it, but they don’t want to be deceived. After all, playing emotional value is still inseparable from those two words: sincerity.

Intelligent assisted driving racing and dark warfare

The wave of intelligence is sweeping the world and profoundly reshaping the transportation field. Chip, lidar, AI algorithm, vehicle-road coordination and other related technologies are rapidly iterated, and scenes such as unmanned taxis and unmanned distribution are gradually landing, pushing the commercialization of intelligent assisted driving into a critical period.

In 2025, the intelligent assisted driving track is no longer just a contest of parameters, but also a race and a dark battle-when the market value list of car companies forms a fault stratification, when the full-stack self-research group and the open cooperation camp are arguing endlessly, when the price of laser radar is halved, when domestic chips are accelerated to replace, everyone wants to "squeeze on the train", who can stay?

The Beijing News reporter initially sorted out that there are at least 300 listed companies involved in intelligent assisted driving business in China, covering the A-share, Hong Kong-share and US-share markets. According to comprehensive data and research reports, there are thousands of companies in the field of intelligent assisted driving in China.

Based on this, according to the public data and corporate information, the Beijing News reporter made an inventory of the functional level of the assisted driving industry, the market value of listed companies, and the number of cooperative customers. Among the A-share listed companies involved in intelligent assisted driving, BYD is the trillion-dollar leader with the highest market value and the highest sales volume of new energy vehicles, Huawei, BYD, Tucki, etc. rank first in the intelligent assisted driving function, and the number of customers of cooperative car enterprises is ahead by Mom en ta.

Behind the competition among market value, ecology and industrial chain is a three-dimensional picture of China’s spiraling intelligent assisted driving industry. Beijing News reporter Lin Zi

Market value competition trillion bibcock and chaser

According to the ranking of the total market value as of May 14, 2025, the top five companies involved in the concept of intelligent assisted driving and the total market value in A shares are BYD, Cyrus, SAIC, Great Wall Motor and Zhongji Xuchuang.

BYD ranks first among A-share intelligent assisted driving companies with a market value of 1.11 trillion yuan. The competition of the second echelon is even more intense. The market value gap between Celestial (213.4 billion yuan), SAIC (192.2 billion yuan) and Great Wall Motor (172.9 billion yuan) is only in the order of billions. In the US stock market, the market value performance of Tucki, Ideals and other new forces is also neck and neck.

Some enterprises related to the industrial chain told the Beijing News reporter that now the automobile factory directly faces the terminal market, which has gained higher attention and higher voice and pricing power. Although technology suppliers are more professional on the technology track, their right to speak is relatively low. As far as the capital market is concerned, it will also favor the automobile factory with larger volume, more brand effect and more "storytelling". This is reflected in the market value. In the Hong Kong stock market, the market value of supply chain enterprises such as Horizon and Black Sesame Intelligence is less than HK$ 100 billion.

Sales volume comparison

Technology Pratt & Whitney and Brand Premium

Further according to the sales comparison, BYD’s sales of new energy vehicles are riding a dust. In 2024, BYD’s global sales of new energy vehicles reached 4.272 million, up 41.26% year-on-year, becoming the global sales champion of new energy vehicles, and its huge sales provided a data foundation for its assisted driving development.

BYD’s competitors are not only domestic car companies, but also compete with Tesla as representatives of China car companies.

While BYD’s sales in 2024 surpassed Tesla’s, the competitive logic behind the two is completely different. Byd relies on the large-scale strategy of "smart driving and equal rights" to sink the intelligent assisted driving technology to the 70,000-yuan market, while Tesla relies on the FSD technology premium to maintain the mid-to high-end positioning. Behind this market value competition are two routes: people-friendly and brand premium.

Battle of ecology

Full-stack self-research and open cooperation

At present, the intelligent assisted driving technology has entered a period of rapid development, and various enterprises have launched differentiated solutions through self-research or cooperation to promote the popularization of functions and upgrade the experience.

Among car companies, BYD and Tucki are both representatives of self-research of car companies, and they also belong to the first echelon. For example, BYD’s self-developed high-order intelligent assistant system is called "Eye of the God". Tucki, Ideal and other car companies are also constantly exerting their efforts in assisting driving.

Some companies do not fully agree with the self-research model of car companies. Wu Yongqiao, president of Bosch Intelligent Driving Control System in China, has publicly stated that in the future, intermediate intelligent assisted driving will become the standard, and the main engine factory will invest hundreds of millions or even billions of dollars in full-stack self-research every year, which is costly and not cost-effective, and should be handed over to the supply chain for processing.

Huawei has always been listed as the first echelon of intelligent assisted driving system. Jin Yuzhi, CEO of BU, Huawei’s smart car solution, said in 2024 that 10 brands of 7 car companies will adopt Gankun solutions, including Chang ‘an Deep Blue, Celestial, etc. It is estimated that there will be more than 500,000 cars driven by Huawei.

In contrast to self-research, Huawei’s "friend circle" model shows another possibility. At present, Huawei has three modes for automobile business, namely, parts supply mode, H I(Huawei Inside) mode and intelligent car selection mode.

Providing spare parts to BMW, BYD and other car companies, referred to as "spare parts supply model". Relying on Huawei’s intelligent solution cooperation, such as Beiqi Extreme Fox and Aouita, referred to as HI mode. Car companies have deep cooperation with Huawei, and Huawei participates in product design, marketing and sales. These models will appear in the Huawei Experience Center, and the intellectual and intellectual circles belong to this kind of cooperation, referred to as the smart car selection model. Among the above three modes, the one with the closest cooperation depth is the smart car selection mode.

SAIC has publicly stated that "the soul should be in its own hands", and now it also chooses to cooperate with Huawei. While Huawei’s partners get the benefits brought by the sales growth of cooperative models, they also need to face the question of "whether the car companies themselves have mastered the core technology", such as whether Cyrus and Jianghuai can independently build high-quality models of their own brands.

More noteworthy is the rise of the middle route. Technology suppliers such as self-driving unicorn M omenta (Beijing Chusu Technology Co., Ltd.) and Baidu Apol?lo are exploring their own unique routes.

Mass production and large-scale application are the key words of M omenta. On May 12th this year, Xiangdao Travel signed a strategic cooperation agreement with Momenta, and the two sides will jointly build the world’s first robotaxi (self-driving taxi) fleet based on the pre-installed mass production scheme, and take the lead in starting operation in Shanghai, which will become a robotaxi fleet that is "born for large-scale application in cities".

Baidu radish run is aimed at overseas. On March 28 this year, Baidu Radish Run announced the signing of a strategic cooperation agreement with Dubai Road Transportation Bureau, and plans to deploy more than 1,000 fully driverless cars in Dubai. This is also the first time that Radish Run has carried out unmanned large-scale testing and service outside China.

The transformation and reconstruction of industrial chain

When the intelligent assisted driving function changed from "high-end label" to "basic configuration", a reshuffle sweeping the entire industrial chain has already started.

The Beijing News reporter combed and found that the competition in the number of customers of assisted driving supply chain enterprises is characterized by wide coverage, large number of cooperation and diversified customer types. All enterprises are striving to expand their customer base in order to gain an advantage in the fierce market competition.

Among them, Momenta is the company with the widest coverage of cooperative car companies, which covers 7 of the top 10 car companies in the world and has more than 130 cooperative mass production models.

In the field of lidar, the two "leading players" are deadlocked and the competition is extremely fierce. Sagitar Juchuang cooperates with 92 models of 28 automakers and first-class suppliers. Hesai Technology cooperated with 120 models of 22 car companies, and won big orders simultaneously under the price reduction strategy.

In an interview with the media in November, 2024, Li Yifan, the founder of Hesai Technology, publicly stated that the company planned to reduce the price of its main lidar products by half to US$ 200 in 2025, which means that electric vehicles with a price less than 150,000 yuan can also use lidar. On February 11, 2025, Hesai Technology announced that various models of BYD will be equipped with Hesai’s lidar products, and it is planned to achieve mass production delivery in 2025.

These news not only show the "involution" of lidar track, but also reflect the bargaining power of car companies. Shen Ziyu, co-founder and chairman of Yikatong Technology, publicly stated in March 2024 that "there will be no laser radar companies and millimeter wave radar companies in the future, only incremental component companies for smart electric vehicles."

The competition on the chip track is even more cruel. Horizon used 9 years to load more than 4 million Journey series chips, which replaced M obileye in L2 market. Under the reality that NVIDIA O rin chips still dominate the high-end market, domestic chip companies still have a long way to go.

In addition to hardware iteration, the battle for software route is equally fierce. At present, the "map-free" route led by Tesla is in fierce confrontation with the "high-precision map" faction adhered to by NavInfo.

Behind the multi-faceted competition, enterprises are also facing common challenges. In the field of intelligent assisted driving, L3 and above autonomous driving technology has not been allowed to go on the road, and no more detailed regulations and regulations concerning the definition of responsibilities and road regulations have been issued at the national level. The commercialization of intelligent driving technology still faces uncertainty.

In addition, whether it is the full-stack self-research of automobile enterprises or the research and development of industrial chain enterprises, from chips, algorithms to system integration, every link needs a lot of financial support. In the future, the investment of tens of billions will continue to raise the threshold of intelligent assisted driving.

Despite this, the panorama of China’s spiraling intelligent assisted driving industry has also begun. BYD’s "intellectual drive and equal rights" have brought assisted driving into thousands of households, and Huawei’s "multi-party cooperation" has continuously broadened the boundaries. The rise of Hesai Technology and Horizon proves that there are no eternal giants in the trillion-dollar market.

How to balance the technical innovation and safety bottom line of assisted driving of the circle round table school?

Since April this year, the Ministry of Industry and Information Technology has carried out strong supervision on the promotion of intelligent networked vehicles, requiring automobile companies to fully carry out the combined driving assistance test and verification, clarify the functional boundaries and safety response measures of the system, and refrain from exaggerating and false propaganda. China Automobile Industry Association and China Automotive Engineering Society also issued a proposal to standardize the promotion and application of driver assistance. For a time, car companies have renamed the sayings of automatic driving, autonomous driving, intelligent driving and high-order intelligent driving as assisted driving.

With stricter supervision, how to balance technology popularization and safety in assisted driving? How to establish a database of assisted driving accidents for cross-vehicle enterprises? The Beijing News reporter invited nine guests, including enterprises and experts, to participate in the "Circle Roundtable School" on topics related to assisted driving development.

Popularizing assisted driving requires safety as the premise.

Beijing News: How to balance the popularization and safety of assisted driving technology?

Lu Fang: First of all, the popularization of assisted driving technology should follow the gradual development path, and each stage should be fully verified to ensure reliability, so as to avoid premature pursuit of "completely unmanned" and ignoring potential risks. At the same time, key systems (such as perception, decision-making and execution) should be designed with multi-sensor fusion, algorithm redundancy and hardware backup, and data should be accumulated through massive virtual simulation tests (covering extreme scenes) and real road tests to optimize the algorithm’s ability to cope with complex scenes. Only when the technology is mature can security be guaranteed.

In addition, when promoting assisted driving technology, we must talk about equal rights and take safety as the basis, so that users can clearly know what the capability boundary of each car technology is. The ultimate goal of assisted driving is to improve users’ travel safety. Enterprises should take "safety first" rather than "speed first" as the principle, and the public should rationally look at the potential and limitations of technology.

Wu Huixiao: Great Wall Motor has always stressed that assisted driving is still in the primary development stage at this stage, and there is still a long way to go before real automatic driving. The core value of assisted driving is to improve travel safety and efficiency, not marketing gimmicks. In addition, we suggest establishing a national public test database for intelligent driving, sharing desensitization accident data, and accelerating the establishment and iteration of safety standards for intelligent driving.

In product communication, enterprises should face up to the development stage of technology, respect its development law, and truly inform users of the availability and applicability of technology, so as to avoid the risk of misuse caused by exaggerated publicity and even affect the overall cognition of China automobile industry.

Wang Haowei: The smarter the algorithm, the greater the security challenge; On the contrary, the safest algorithm is the simplest logic. Therefore, the core issue of the popularization of assisted driving is to find a balance between intelligence and safety. Absolute security can’t be achieved. What’s more important is to let the end users know the capability boundary of the system, instead of relying too much on the system capability. Safety is a comprehensive project, and there is no once-and-for-all approach. Efforts should be made from system design, algorithm, security mechanism, user training, regulations and new technologies.

Zheng Zhuangcheng: The popularity and safety of assisted driving are not antagonistic, but "two sides of one body" that need to be promoted together. Balancing the two needs to be realized from several dimensions: first, technical iteration is carried out with ensuring safety as the lowest level of assisted driving requirements; The second is to establish an industry safety baseline; The third is user education, which pays equal attention to popularization and transparency; The fourth is ecological synergy, and the responsibility of the whole industry chain is shared.

Dai Yifan: The essence of assisted driving application is to improve safety. It is meaningless to talk about popularizing assisted driving system without safety guarantee. Therefore, there is a "priority weight" relationship between the two, and it must be on the premise of ensuring safety and improving the existing driving safety before promoting the assisted driving system.

Need to break the "absolute trust" in assisted driving

Beijing News: In view of the public’s "absolute trust" in assisted driving, how to rebuild a transparent communication mechanism?

Wang Haowei: Absolute trust is a dangerous term, because there is no absolutely safe system. The relative trust of the public in assisted driving is what the industry needs to pursue. Relative trust means with boundaries and conditions, and it also means that we must pursue the best under certain conditions, not the global optimal solution.

Zheng Zhuangcheng: Transparency is a technical safety belt in the era of assisted driving. NavInfo rebuilds public trust based on three core measures: technical transparency, real-time update and "data security is the cornerstone of building smart driving security".

Dai Yifan: At present, assisted driving requires drivers to stay in the loop and stay awake, especially in some abnormal road scenes. Assisted driving requires popular science rather than hype. The so-called "assistance" means helping drivers, and there must be some guidance in propaganda.

Zhuang Jinggan: Many people think that the "smart driving" system is safe and reliable enough, but this is not the case. This misunderstanding largely comes from the early propaganda strategy of car companies, which makes consumers mistakenly think that technology is mature enough to replace human driving, ignoring the capability boundary and potential risks of the system.

Viewpoint 3

The database of assisted driving accidents suggests that the government should take the lead.

Beijing News: It is suggested that a database of assisted driving accidents across car companies can be established to provide a technical basis for the determination of responsibility. What do you think?

Wang Haowei: To establish a database of assisted driving accidents of cross-vehicle enterprises, it is necessary to introduce relevant data uploading standards at the national level, and it is best to enforce them.

At the same time, the balance between the bottom line of safety and the development of the industry should be taken into account in the determination of responsibility. If all the responsibilities are put on car companies, it will lead to the lack of awe of the public in using the assisted driving function, which will eventually inhibit the motivation of car companies to develop assisted driving.

Zhuang Jinggan: "Government-led, joint car companies to build a unified national database" is helpful to standardize industry practice. At present, there are great differences in technical routes and data formats among car companies. If they are independent, they will form "data islands", which cannot support the general standards of the industry. The government can take the lead in formulating data collection standards, and car companies can access key information such as operation logs, sensor data and system decision records, and establish a privacy protection mechanism to desensitize sensitive information.

After the completion of the database, it is necessary to clarify the framework of responsibility division, and it is suggested that the legislature should formulate special laws, and at the same time clarify the criteria for identifying technical defects and dynamically divide the proportion of man-machine responsibility. In addition, we can also consider establishing a "data black box" system and handing over the right of data analysis to a third-party authority.

Auxiliary driving will develop in the direction of equal rights.

Beijing News: Do you think the development of L3 or L4 autopilot will be hindered? What is the trend of assisted driving?

Lu Fang: The development of L3 or L4 may be hindered, but the overall trend is still forward. Although the existing technology has covered most conventional scenes, some extreme scenes (such as rainstorm, blurred road markings and sudden obstacles) are still the core obstacles for L3 and L4 to land. Coupled with the public’s lack of awareness of autonomous driving technology, the wide application of L3 and L4 technologies is limited to some extent.

However, at present, the industry has L3-level technical reserves, and the Ministry of Industry and Information Technology is also accelerating the improvement of the automatic driving standard system, promoting the safety baseline construction, and the industrial chain is also upgrading in coordination. These are all positive aspects.

Deng Chenghao: The current policy’s regulation of L2 function is essentially an "ice-breaking action" to pave the way for advanced autonomous driving. This will not hinder the development of L3/L4, but instead build three booster engines. The first is to establish the coordinate system of technological evolution. The latest national standard "Auto Driving Automation Classification" issued by the Ministry of Industry and Information Technology defines the responsibility dividing line (ODD operation design domain) between L2 and L3 for the first time, which will accelerate the shift of consumers’ cognition from "whether there is function" to "capability boundary" and clear the cognitive obstacles for the commercialization of L3/L4. The second is to open up the fast lane of technology verification, and the "car-road-cloud" three-dimensional verification system will shorten the technology maturity cycle by 30%. The third is to reconstruct the ecology of industrial cooperation, and institutional breakthroughs are more strategic than simple technical breakthroughs.

Zheng Zhuangcheng: From the perspective of four-dimensional map and safety redundancy, the future development trend of assisted driving will not be separated from the map. AI big model helps high-order intelligent driving to accelerate landing, but high-precision map is always an indispensable transcendental sensor to assist driving. The so-called "no map" will bring a series of problems such as increased cost and irregular data collection.

Zhang Ruixue: The large-scale landing of assisted driving mainly faces several problems: First, the perception and decision-making of complex scenes (such as non-signal scenes and complex environments) is still the core difficulty. The existing bicycle intelligence relies on multi-sensor fusion, but the hardware stack (such as laser radar) is expensive and cannot completely cover all long tail scenes. Second, the division of responsibility for autonomous driving accidents in the current law is not clear, and the insurance system also lacks an adaptation plan. Third, the data closed-loop ability is insufficient. High-order autopilot relies on the collection, labeling and model training of massive scene data, but the existing test area is limited in openness, resulting in insufficient data diversity.

Zhuang Jinggan: The landing of L3/L4 autopilot faces three core challenges: first, the long tail scene processing, that is, the reliability of the system is insufficient in extreme or rare scenes; Secondly, the law lags behind; Finally, the lack of infrastructure coordination, especially the slow progress of vehicle-road coordination (V2X). In the future, whether it is L2, L3 or L4 level assisted driving, it will develop in the direction of equal rights. This is mainly due to the rapid decline in the cost of the core components of assisted driving, and the technology is breaking through the high-priced barrier and moving towards large-scale application.

Dressing up a new design language Toyota’s new RAV4 rendering exposure

A few days ago, Chezhi. com obtained a set of brand-new RAV4 renderings of Toyota from relevant channels. The new car will adopt the brand-new family design language, and it is expected to debut in the first quarter of next year at the earliest, and the domestic version is expected to be launched in the second half of next year.

As a replacement model, Toyota’s new RAV4 will adopt a new family design language. Among them, the front face is similar to the Camry currently on sale. The interior of the headlights adopts LED daytime running lights similar to "boomerang" style, and the middle of the headlights on both sides is connected by air inlets, which has a visual stretching effect. In addition, the bottom will be equipped with a matrix lower grille, and the silver protective plate at the bottom will enhance the sense of security to some extent.

The overall shape of the tail continues the current round and full design technique, and it is equipped with the popular penetrating taillights, and the bottom is surrounded by a huge black back, which is also full of security.

In terms of interior, although no more information is disclosed at present, it is speculated that the new car may also adopt the same design elements as the current Camry, equipped with LCD digital instrument panel and large-size floating LCD central control panel.

In terms of power, the new car will provide a 2.5L oil-electric hybrid system and a 2.5L plug-in hybrid system.

Focus on one-on-one express brand flash with big moves! Take multiple measures to eliminate potential safety hazards for riders

　　In recent years, the protection of riders’ rights and personal safety has attracted more and more attention from all walks of life. In order to further strengthen and standardize the traffic order management of the instant delivery industry and prevent and reduce the occurrence of road traffic accidents in the instant delivery industry, flash delivery can be said to have been working hard, insisting on the "one-on-one express delivery" mode to build a safety barrier for platform riders.

　　Flash delivery focuses on "one-to-one express delivery", which only delivers one order at a time. The delivery range is large, which mainly meets people’s needs in emergency delivery and important goods delivery. Therefore, the unit price of customers is relatively high, which tests the platform’s accurate matching and global scheduling ability for orders. In order to make the order more accurate, the flasher has less idle driving time and higher efficiency of running the order, the order matching system is established in flasher. In order to cross-dispatch orders from the perspective of global optimization, and to maintain the optimal balance between supply and demand between orders and flashers in each area of the city, a dynamic intelligent scheduling system was built for flasher.

　　In addition, the flash delivery also set aside a certain life time for each order, so as to prevent the flash delivery staff from violating traffic rules in order to catch up with time and avoid potential safety hazards. Many flash delivery staff said that they are not only free to take orders, but also calm to deliver orders.

　　In addition to leaving enough time for flashers to deliver tickets, flashers have always insisted on providing traffic safety training for riders, and even set up a "traffic safety volunteer service team" composed of flashers to actively publicize traffic safety knowledge. For example, in cities such as Hangzhou, Shenzhen, Beijing, etc., the local traffic police are specially invited to come to the Knight’s House, the exclusive offline space of the flash driver, to explain the traffic safety knowledge in a simple way through real cases and enhance the safety awareness of riders.

　　In addition, in order to help riders better deal with all kinds of unexpected situations encountered on the way to delivering tickets, they also regularly carry out red cross first aid training for riders. Nowadays, more and more riders carry maintenance tools and emergency medicines with them, becoming the maintainers of traffic order and small "rescue stations".

　　Flash delivery has always focused on one-on-one rush delivery, taking multiple measures to eliminate potential safety hazards for riders, and conducting traffic safety training from time to time, which not only ensures the personal safety of the majority of flash delivery personnel in the delivery process, but also makes them feel comfortable and happy to take orders, and contributes to building a harmonious and orderly traffic environment.

The opening of MWC is imminent, and Meizu’s big moves are frequent! Flyme dual system attention is full

　　There are still 2 days left! This year’s annual event in the technology industry, the MWC Shanghai Mobile World Congress in 2023, is about to open. As an annual blockbuster conference in the technology industry, although it only lasts for three days from June 28 to 30, it can make the world’s technology enthusiasts focus on it in just three days. Therefore, the annual MWC is also a good opportunity for major technology companies to do their best to show their technologies and products to the world.

　　As the most high-profile Meizu in the first half of this year, it is not surprising to announce its participation in the exhibition. But it is worth noting that Meizu is not participating in the exhibition under the name of "Meizu Mobile Phone", but under the name of "Xingji Meizu Group". That is, at this exhibition, Meizu 20 series will be exhibited together with Flyme Auto.

　　The re-participation of Flyme Auto has also greatly aroused the attention of many professional car critics. After all, Flyme Auto has won praise from many netizens and fans since its debut at the Shanghai Auto Show at the beginning of the year. The user-friendly desktop selection, the highly intelligent option of air conditioning, the logic of car-machine interaction and the UI animation of one mirror to the end have all had an impact on the entire smart car field. Therefore, how much Flyme Auto can be upgraded and optimized at this MWC has also become the most concerned point in the entire new energy vehicle field.

　　In terms of smart end points, the Meizu 20 series, which continues to slaughter the list on the 618, will also become another highlight on MWC! The perfect combination of boundless aesthetics, powerful performance and Flyme10 can be called the embryonic form of future mobile phones.

　　In terms of appearance, the Meizu 20 series is adhering to the unbounded aesthetics and building the appearance. The screen uses extremely thin four-level narrow edges to minimize the boundaries of the screen, and uses narrow borders to further set off the visual perception of the screen. Let the narrow borders and high-quality screens complement each other to build a stronger visual impact.

　　And the back of the phone is also completely different from the dazzling lens group currently on the market. Meizu uses extreme simplicity to present an unbounded beauty, and cancels all the designs that affect the beauty of the back cover! Only the basic lens camera components are retained, and the simplest arrangement is used to build the most refreshing and refined unbounded beauty.

　　In terms of performance, the Meizu 20 series is equipped with a Snapdragon 8Gen2 processor. This chip is also the top flagship processor in the industry. Its performance is excellent, and it is TSMC’s 4-nanometer process. The advantages of low power consumption make the temperature control of the overall mobile phone particularly good. At the same time, the Meizu 20 series also uses a combination of LPDDR5X and UFS 4.0 storage, which greatly enhances the reading and writing speed of the mobile phone, making software and files open and run faster. After Meizu’s careful polishing of this set of performance configurations, it also easily ran out of a high score of 1.3 + million.

　　On the system, the Meizu 20 series comes standard with the Flyme10 operating system. As a software sector that Meizu has always been proud of, this time Flyme10 did not disappoint Meizu. This generation has upgraded the small window mode, Aicy screen recognition and OneMind, and the overall system convenience and smoothness are more convenient. And it can also achieve the background survival of 21 APPs at the same time, completely saying goodbye to killing the background! And it has also passed the test of the Thiel laboratory, which is certified to last for 48 months.

　　The simultaneous demise of the Meizu 20 series and Flyme Auto has filled many people’s expectations for Meizu’s MWC tour!

Employees use computers to read novels at work, and the dismissed labor department intervened in the investigation.

The personnel documents of the company seen by the reporter.

　　The labor department of a large enterprise in Shunde intervened in the investigation and asked the company to "advocate humanized management"

　　Recently, a mysterious informant sent an internal report from a large electronics company in Shunde to the email address of this newspaper, saying that two workers were "immediately dismissed" because they found that they were reading novels on computers at work and sleeping at their posts.

　　In the email, the informant mentioned the strict personnel management regulations recently promulgated by a large company, saying that "some trivial matters in the regulations can lead to the dismissal of employees; The real implementation of the results is stricter than the promulgated regulations! "

　　The reporter then contacted the relevant departments in Shunde and received the investigation report yesterday afternoon. The Shunde district government attached great importance to this matter, sent people to conduct a special investigation on the dismissal of the enterprise, and has urged the company to pay economic compensation and notice in lieu to the dismissed employees in accordance with the Labor Contract Law and other relevant laws and regulations. In view of the fact that it is still in the shadow of the financial crisis, the relevant departments in Shunde District have asked the company to "advocate humanized management". "It is very unreasonable to dismiss people just because of a small fault." A staff member of the district government told reporters.

　　Report: Being fired for chatting while sleeping was punished.

　　The personnel management regulations recently formulated by a large company in Shunde set many harsh conditions, such as "no snacks during office hours, and the labor contract is terminated for those who have accumulated twice", "Playing mobile phones and chatting during office hours, and the labor contract is terminated for those who have accumulated twice …" Recently, a mysterious e-mail was sent to our newspaper’s email address, and the attachment stated the whole story of a large company in Shunde dismissing two employees. Among them, Tan was immediately dismissed for reading novels with a computer during office hours. Other employees were punished by 300 yuan’s "education fund" for chatting, playing mobile phones and listening to music.

　　The mysterious informant said that the previously promulgated regulations stipulated that two violations would be found before dismissal; But now, just because an employee is found reading a novel on a computer, he is fired immediately. "The result of his actions is even more shocking!"

　　Investigation: Sleeping employees are compensated

　　After receiving the relevant email, the reporter immediately reported it to the relevant departments in Shunde District and attached relevant information. Yesterday afternoon, after an investigation by the Shunde district government, it was proved that this was the case. A staff member who participated in the investigation said that the enterprise’s practices were not satisfactory. "Although the current economic environment is not optimistic, such harsh dismissal regulations are unreasonable in managing workers."

　　After investigation, it was found that Qin, who was fired from reading novels at work, had applied to the company for resignation in mid-February this year and was approved by the company before being found out of the so-called "violation of discipline"; Under the supervision of the labor department, Xu, who was fired because of a sleepiness, has reached a consensus and signed an agreement to terminate the labor relationship. At the same time, the labor department requires the company to pay economic compensation and notice in accordance with relevant laws and regulations.

　　Relevant departments: advocate humanized management

　　The staff of relevant departments in Shunde told reporters that this incident has attracted considerable attention from the district government. "Although it is only an individual incident, in the immediate environment, the welfare of workers and all aspects of protection should be well supervised, and large-scale vicious layoffs should not be allowed in enterprises."

　　The material of the mysterious whistleblower was completely true after investigation by relevant departments in Shunde. The relevant departments in Shunde District have asked the company to strengthen communication with employees, advocate humanized management, and try to give priority to criticism and education in dealing with individual employees’ violations and listen to employees’ demands.
