　　Developing autonomous driving technology is an important content of building a transportation power. In recent years, with the rapid development of new technologies such as artificial intelligence, 5G and big data, the application of autonomous driving technology in the field of transportation has been accelerated, and the rapid iteration from closed site testing to road testing and from pilot demonstration to commercial trial operation has been realized.

　　The Ministry of Transport recently issued the "Guide to Transportation Safety Services for Self-driving Vehicles (Trial)" (hereinafter referred to as the "Guide"), which made it clear for the first time from the national policy level that intelligent networked vehicles can be used for transportation business activities, and pressed the "acceleration button" for the commercial application of self-driving technology in China.

　　What is the development of autonomous driving technology at present? How to improve the safety guarantee ability of autonomous driving? The reporter interviewed the relevant person in charge of the Ministry of Transport and relevant experts.

　　The market scale is growing rapidly, and it is steadily moving towards commercial application.

　　"With the joint efforts of all parties, in recent years, China’s autopilot-related industries and market scale have shown a rapid growth trend, and autopilot technology has steadily moved from testing and demonstration to commercial application." Zhang Jinhua, chairman of China Automotive Engineering Society, introduced.

　　The industrial development environment continues to improve. At present, 17 national-level test demonstration zones, 7 national-level vehicle networking pilot zones and 16 "Shuangzhi" pilot cities have been built nationwide, with a cumulative open test road of over 22,000 kilometers and a cumulative test mileage of over 70 million kilometers. Beijing, Shanghai, Guangzhou, Shenzhen and other cities have introduced policies to allow self-driving cars to engage in commercial trial operation of urban public buses, taxis, logistics and distribution in specific areas and at specific time periods, and the application scale has been expanding.

　　In Shunyi District, Beijing, hundreds of bright yellow automatic delivery vehicles appeared in the streets and lanes, waiting for traffic lights side by side with pedestrians, or avoiding other vehicles safely on the road. "After years of iterative upgrading, unmanned delivery vehicles can not only ‘ Get ’ , can provide consumers with ‘ Send it quickly ’ Service experience. " The person in charge of the automatic delivery department of Meituan said that at present, in Shunyi, the daily delivery orders of automatic delivery vehicles of Meituan have reached thousands.

　　In the Economic Development Zone of Wuhan, Hubei Province, open the "radish run" taxi software, and you can quickly call an unmanned self-driving car by setting the starting point and the ending point. Passengers click "OK" on the back screen, and the vehicle can travel according to the established route. "The fisheye camera and laser sensor on the roof device can help the vehicle avoid obstacles accurately and automatically adjust the speed according to the road conditions." According to the person in charge, 300 driverless cars have been put into operation since the unmanned self-driving travel service was opened in Wuhan in August 2022, covering a population of over 4 million.

　　The application of industry innovation has accelerated. Scene-level autonomous driving solutions have accelerated to maturity, and some autonomous driving products have reached the conditions of mass production application, and have been applied to transportation service scenes such as urban travel and freight logistics on a certain scale, and new formats such as autonomous parking service and unmanned distribution have emerged continuously. At present, there are more than 200 self-driving city buses, more than 1,500 self-driving taxis and about 1,000 self-driving trucks in China. Baidu Apollo autopilot test has a total mileage of more than 78 million kilometers, and its travel service covers more than 10 cities.

　　With the continuous expansion of market scale, it is urgent to strengthen industry norms. "At present, the basic requirements for using self-driving cars for transportation operations are still unclear, which is not suitable for the healthy and orderly development of self-driving cars, and the safety pressure is increasing." The relevant person in charge of the Transportation Service Department of the Ministry of Transport said that the Guide clarified the basic requirements for using self-driving cars to engage in transportation business activities under the framework of current laws and regulations, and guided the healthy development and standardized application of self-driving cars in the field of transportation services in an orderly manner while ensuring transportation safety.

　　Build a security system to provide compliance for business activities.

　　Transportation services are related to the national economy and people’s livelihood. Continuously improving the safety and security capability is the primary goal of transportation services, and it is also the basic requirement for the promotion and application of self-driving cars in transportation services. Sorting out the measures in the Guide, the word "safety" runs through.

　　"Adapting to the development trend of autonomous driving, the Guide focuses on ensuring the transportation safety of autonomous vehicles. Under the condition of meeting the requirements of relevant departments for the access and road traffic of autonomous vehicles, it puts forward requirements for the production conditions and qualifications of transportation operations, dynamic supervision and emergency handling of vehicle operation, and operational supervision, and guides the transportation safety services of autonomous vehicles in all directions and in the whole chain." Zhang Jinhua said.

　　In terms of technical standards, the Guide clarifies the technical requirements for self-driving cars, emphasizing that "self-driving cars engaged in taxi passenger transport, road passenger transport and road cargo transport should also meet the requirements of technical standards for operational motor vehicle safety in the transportation industry". "This move has achieved the connection with the management boundary of self-driving cars in the departments of industry, information and public security." Li Bin, vice president of the Highway Research Institute of the Ministry of Transport, said.

　　In terms of personnel allocation, the Guide specifically puts forward the concept of "safety officer" in view of the safety problems during driving.

　　"The on-board driver or operation safety guarantee personnel of the self-driving car is ‘ Safety officer ’ 。” Li Bin said that the Guide fully considers the business models of self-driving transportation with different formats, and provides for the allocation, skills and qualification requirements of safety officers engaged in different transportation business activities by classification on the premise of ensuring safety. Among them, in view of the application scenario of fully self-driving cars engaged in taxi passenger transport, the form of personnel support for remote safety officers is put forward in particular, and it is clear that "with the consent of the people’s government of the district and city, remote safety officers can be used when operating in designated areas, and the ratio of people to vehicles of remote safety officers should not be less than 1: 3".

　　"Overall, the Guide has built a safety guarantee system from six aspects: safety production system, transportation safety guarantee, running state information management, vehicle dynamic monitoring, safety notification and emergency response." Li Bin believes that under the premise of being consistent with the current road transportation management, the Guide fully combines the new characteristics of self-driving car transportation, and provides compliance for self-driving cars to engage in road transportation business activities safely.

　　Classified scenarios provide normative guidance to accelerate the application of technology.

　　As a new technology, autonomous driving has been widely used in various transportation service scenarios. Different scenarios have different design and operation conditions, different security risks and different risk level requirements. In order to further ensure safety, "classified policy" has become a highlight of the Guide.

　　The Guide clarifies the application scenarios of self-driving cars to carry out road transport services. For urban public buses and trams, related passenger transport business activities can be carried out under the scenes of physically closed, relatively closed or simple road conditions with fixed lines and controllable traffic safety; For taxis, passenger transport business activities can be carried out in the scene of good traffic conditions and controllable traffic safety; At the same time, self-driving cars are prohibited from engaging in road dangerous goods transportation business activities. At the same time, the Guide clarifies the requirements for "self-driving transport operators", and taxi passenger transport and road passenger transport should be insured with carrier liability insurance according to law.

　　"Standardizing the application of self-driving cars in the field of transportation services by classification, scene and level will effectively guide all kinds of transportation service business activities to carry out self-driving applications, effectively ensure the safety of self-driving transportation services, and promote the healthy and orderly development of commercial applications of auto-driving." Wang Advanced, vice president of the Research Institute of the Ministry of Transport, said.

　　The overall scale of China’s automobile industry remains in the forefront of the world, and the production capacity and application technology level have been greatly improved. As an important breakthrough to improve the level of industrial intelligence, autonomous driving has been valued and supported by relevant departments.

　　In 2020, the Ministry of Transport issued the Guiding Opinions on Promoting the Development and Application of Road Traffic Autopilot Technology; In 2021, the Ministry of Industry and Information Technology issued the Opinions on Strengthening the Access Management of Intelligent Networked Automobile Manufacturers and Products; In November 2023, four ministries and commissions, including the Ministry of Industry and Information Technology, issued the Notice on Launching the Pilot Work of Intelligent Networked Vehicle Access and Road Access, which covered the key links of vehicle use, such as production access and road management of automobile products, and the management policies for the production and use of self-driving vehicles were gradually established … … In recent years, various ministries and commissions have accelerated the research on policies related to the commercial application of autonomous driving and issued a series of policy documents.

　　"The increasingly perfect industrial development environment has made it possible for self-driving cars to accelerate their application in transportation services." Wang Advanced said that the release of the Guide has established a safe bottom line for the application of self-driving cars, and also left enough room for the innovative application of autonomous driving, which will further promote the application of autonomous driving technology in the transportation field.

"With the continuous increase in R&D investment by Android manufacturers and upstream supply chains, the hardware technology has improved and matured, the application of software systems has been optimized, and the consumer experience has been continuously improved. The further decline in prices has also made more consumers willing to use folding screen mobile phones early. "

On February 20th, the latest quarterly tracking report of mobile phones released by International Data Corporation (IDC) showed that in the fourth quarter of 2023, the market shipment of folding screen mobile phones in China was about 2.771 million units, up 149.6% year-on-year. A number of new products from Huawei, OPPO and Glory promoted the rapid growth of the folding screen market in this quarter.

In 2023, the China folding screen mobile phone market shipped about 7.007 million units, up 114.5% year-on-year. Since the launch of the first product in 2019, the folding screen mobile phone market in China has grown by over 100% year-on-year for four consecutive years.

However, folding screen mobile phones still often appear "the screen is not resistant to falling, the maintenance price is expensive, and the screen itself is prone to problems". Guo Tianxiang, senior analyst of IDC China, told the Beijing News Shell Finance reporter that with the continuous progress and maturity of technology, especially the increasing participation of domestic supply chains, some problems related to folding screens will continue to improve. "But it still takes more time to completely solve it."

The price of folding screen dropped to 400-600 dollars.

The market share of transverse folding products increased to 68% again.

The price of folding screen mobile phone continues to drop. According to IDC data, in 2023, the share of mobile phones with folding screens above $1,000 has dropped from 81.0% a year ago to 66.5%, down 14. 5 percentage points year-on-year. In addition to the overall cost reduction, the products in vertical folding form are relatively cheaper, which also makes the price of folding screen drop to the price range of 400-600 dollars in 2023.

In terms of product form, horizontal folding products are more popular with consumers in China. Although the price of vertical folding products is relatively lower, horizontal folding products have been favored by more consumers in China because they can better reflect the big screen experience of folding screen mobile phones. In 2023, the market share of transverse folding products increased to 68.1%, up by 10.4 percentage points year-on-year.

At present, the vertical folding products are not only easy to carry, but also consumers still lack the necessary use scenarios. At the same price, there is also a clear gap between the use experience and the straight board machine, and there is still room for improvement in product quality.

IDC pointed out that the importance of horizontal folding products in the mobile office scene of high-end business people is increasing. At the same time, the high-end people pay less attention to the price, and are more willing to choose the horizontal folding products with full product configuration.

Recently, it has been reported that individual mobile phone manufacturers have stopped planning to release new small folding models this year. In this regard, Guo Tianxiang said to the Shell Finance reporter that it is mainly a demand issue. "There is no rigid requirement for vertical folding usage scenarios. The sales volume is not up, the price is not high, and the product quality problems lead to great after-sales pressure, and the final cost is high, and most manufacturers are losing money. Individual manufacturers are not saying that they will not do it at all, but they will be suspended. When the supply chain technology is more mature and the cost and quality are better, they may come back. "

Huawei occupies the first place in the domestic folding screen market in 2023.

Folding screen is still the key product of various manufacturers in 2024.

In terms of the market performance of folding screen mobile phone manufacturers, the above report pointed out that Huawei Mate X5 series has been in a state of price increase since its listing, and the supply is in short supply, helping Huawei firmly occupy the first position in the domestic folding screen market in 2023, with a market share of 37.4%.

OPPO gained 18.3% market share and ranked second in the overall folding screen market; Among them, the market share of vertical folding products ranks first with 36.3%; The horizontal fold Find N3 series has been widely praised around the world.

Glory made great efforts in the folding screen mobile phone market in the second half of 2023, and won the third place in the folding screen mobile phone market for the whole year with the hot sales of Magic V2 and other new folding products, with a share of 17.7%, and the shipment volume increased by 467.0% year-on-year, with the fastest growth rate.

Samsung occupies more than half of the global folding screen mobile phone market, but ranks fourth in the highly competitive China market with 11% market share. Vivo ranks fifth, and its first 5G horizontal folding product X Fold 2 released in 2023 is about to be replaced.

Guo Tianxiang concluded that "thinness" has become the primary factor affecting consumers’ choice of folding screen mobile phones. However, if the pursuit of "thinness" blindly leads to the decline of reliability, it will directly affect consumers’ long-term choices in the future. However, the use scenario of vertical folding products has not been fully discovered, and products that position potential users as "fashionable young women" will form direct competition with Apple.

"Folding screen mobile phones are still the key products of various manufacturers in 2024. The participation of more manufacturers and the launch of more products will continue to promote the rapid development of the folding screen mobile phone market. " Guo Tianxiang said.

In addition to the flexible size of the screen itself, will there be some new innovation highlights compared with the straight board machine? In this regard, Guo Tianxiang responded to reporters that vertical folding products are more convenient to carry after folding. Horizontal folding products are mainly the advantages of large screen, but more need to be reflected by the adaptation of software system applications.

Chatelet Opera House, Golden Globe Festival. When Beckham handed the Golden Globe Award to Messi, the audience stood up and gave applause!

This is a tribute to the ball king. During the performance inspection period of the 2023 Golden Globe Awards (from August 1, 2022 to July 31, 2023), Messi contributed 42 goals and 26 assists, as well as the World Cup champion, World Cup MVP and Ligue 1 champion trophy. The 8 th Golden Globe Award is in hand, and Messi leads alone in the century-old football.

Messi smiles and accepts the award, and we will think of Cristiano Ronaldo, one of the peerless double arrogance.

38-year-old Cristiano Ronaldo, will he feel "injured"? Cristiano Ronaldo is really a little injured-Cristiano Ronaldo, who played successfully in Riyadh, suffered a slight bruise on his ankle, which did not affect his play. The Golden Globe Award is 5-8 behind Messi, and Cristiano Ronaldo, who is competitive, is hard to quiet inside.

Sports media all over the world gave the front page headline of the cover to Messi, who was holding the Golden Globe Award, and the praise was overwhelming. At this time, Riyadh, Saudi Arabia is already late at night, and Cristiano Ronaldo may have fallen asleep, preparing for the quarter-final of Saudi Arabia’s "Guardian Cup of Two Holy Temples" on the second day, or the quarter-final of Saudi Arabia’s King’s Cup, without much attention.

At this moment, we can feel the fact more: the dispute between the peerless and arrogant has ended.

On December 10, 2022, Portugal was eliminated in the quarter-finals, and Cristiano Ronaldo said goodbye with tears; On December 18, 2022, Messi won the sacred World Cup under the crowd, and the global media all exclaimed that "the new ball king was born". In just 8 days, the peerless double pride has embarked on a different track, and its historical position has been frozen.

In the twilight of his football career, Messi made a great leap to lift the World Cup and achieve the greatest goal. C Ronaldo left regrets and explained disappointment and unwillingness with tears. On the night of the Golden Globe, Messi was crowned with the Golden Globe Award for the eighth time-this is the continuation of Messi’s joy and Cristiano Ronaldo’s sadness in the World Cup, which really ended the dispute between the two arrogance.

The era of double arrogance PK has ended, and the era of Messi and Ronaldo has also ended.Messi in Miami and Cristiano Ronaldo in Riyadh are veterans running in the afterglow of sunset, and the direction of sunset is the time to hang up your boots. This day will come eventually, and watch and cherish it.

The future belongs to Bellingham and Harland. Premier League, Champions League, La Liga, this is the sun-like stage, the center of world football. The dispute between Messi and Cristiano Ronaldo is no longer the mainstream-although the two veterans can still contribute to the monopoly level of heat and topic, the gods also have the end of the day, and next year’s Golden Globe Award is likely to completely turn over the page of double arrogance.

CCTV News:After long summer, the temperature in various places has risen, and it is the season when a large number of seasonal fruits such as cherries and watermelons are on the market. What about the recent fruit prices? Let’s look at the reporter’s investigation.

In Beijing Xinfadi Agricultural Products Wholesale Market, fruit merchants told reporters that after the May 1 holiday, a large number of watermelons were listed in Shandong, Jiangsu, Beijing and other places, and the prices went down. On May 9, the average price of watermelons in Xinfadi Market was 4.82 yuan per kilogram, which was 20% lower than that on April 29, and 33% lower than that on April 9, while the varieties with higher prices in the previous period also dropped significantly recently.

Ma Jing, a fruit merchant in Beijing Xinfadi Market:Cherry from Dalian, Liaoning, and cherry from Shandong are on the market in large quantities. Last month, it was a kilo in 60 yuan, and now it is a kilo in 40 yuan.

Xu Jingju, a fruit merchant in Beijing Xinfadi Market:(Originally) high prices are now declining, such as litchi, which started at more than 200 yuan a box, and now it has dropped to 70 yuan (a box).

The data shows that in April, the average wholesale price of six kinds of fruits monitored by the Ministry of Agriculture and Rural Affairs was 7.90 yuan per kilogram, up 0.3% from the previous month and 10.5% from the same period last year. After May, with the warmer weather, seasonal fresh fruits such as watermelons and melons in the south, cherries, strawberries and mulberries in North China and Central China entered the harvest period one after another, and the market supply and varieties of fruits increased.

Wang Yunjuan, chief fruit analyst of the agricultural product market early warning team of the Ministry of Agriculture and Rural Affairs:Since May, the national average wholesale price of fruits has declined slightly, mainly due to the large number of melons and other fruits listed, of which the weekly average price of watermelons has dropped by 6%, down by 25% year-on-year. It is expected that fruit prices will enter a seasonal decline channel in the later period.
