Today, intelligent and connected vehicles are more common in people's lives.
From September 16th to 19th, the 2022 World Intelligent Connected Vehicle Conference was held in Shunyi District, Beijing, with more than 200 exhibitors from the global intelligent network connection field.
The conference provides a window for the audience to have a close-up understanding of the current new technologies, new products and new formats of the intelligent networked automobile industry.
Open road test in many places
The industry ushered in rapid development
"How come there is a street sign of Rongjing East Street in the exhibition hall?" At the booth of the high-level autonomous driving demonstration area in Beijing, many visitors found that the exhibition "moved" an open road for intelligent vehicle connection located in the Beijing Economic and Technological Development Zone. .
Through the large screen, visitors can see that sensors and wireless communication technology equipment are installed on the street light poles on both sides of Rongjing East Street to collect road information in real time; at the bus stop on the side of the road, passengers board the unmanned driver in an orderly manner Buses; in the square in front of the office building, someone is buying drinks through unmanned retail vehicles.
"These are the results achieved in the 1.0 and 2.0 stages of the high-level autonomous driving demonstration area in Beijing." The staff of the exhibition area told reporters that since the construction of the demonstration area in September 2020, 329 intelligent network connections have been built in the Beijing Economic and Technological Development Zone. Standard intersections, two-way 750-kilometer urban roads and 10-kilometer expressways have realized the integrated function coverage of "vehicle, road and cloud", and a city-level engineering test platform has been initially built.
At present, the construction task of the 3.0 stage of the demonstration area has been fully started. In the future, Beijing will also build a unified smart city dedicated network for the whole city, and gradually realize the global signal coverage along the road in the 3.0 stage; promote the adaptive application of more than 1,000 high-level vehicle terminals; establish a city-wide Unified standard cloud control platform, etc.
Not only Beijing, but more and more cities across the country are vigorously promoting the coordinated development of the ICV industry.
Guangzhou City, Guangdong Province promulgated the "Guiding Opinions on Road Testing of Intelligent Connected Vehicles", allowing vehicles that have obtained remote testing qualifications to conduct unmanned autonomous driving tests on public roads under the guarantee of remote monitoring.
In March this year, Chengdu High-tech Zone in Sichuan Province issued the first batch of 12 driverless test license plates, and 4 driverless buses and 8 driverless taxis were put on the road for testing.
Relevant ministries and commissions also provide policy support for the development of the intelligent networked vehicle industry.
Recently, the General Office of the Ministry of Natural Resources issued the "Notice on Doing a Good Job in the Pilot Application of High-precision Maps of Intelligent Connected Vehicles", and launched high-precision maps of intelligent networked vehicles in six cities of Beijing, Shanghai, Guangzhou, Shenzhen, Hangzhou and Chongqing. Apply pilot projects to form a safe application technology path and demonstration model for autonomous driving-related maps that can be replicated and promoted nationwide.
The Ministry of Transport announced the first batch of pilot projects for pilot applications of intelligent transportation, covering pilot projects from more than 10 cities including Beijing, Tianjin, Shanghai, Changchun and Hefei.
"The pace of development of intelligent and connected vehicles is accelerating, and policies and regulations are an important guarantee for the rapid development of the market." Guo Shougang, deputy director of the First Division of Equipment Industry of the Ministry of Industry and Information Technology, said at this conference that nearly 30 cities across the country have accumulated a total of 80 Several companies have issued more than 1,000 road test licenses.
At the same time, domestic ICV enterprises insist on independent innovation, and promote the industry to usher in a period of rapid development.
At the opening ceremony of the conference, Xin Guobin, vice minister of the Ministry of Industry and Information Technology, said that in the first half of this year, domestic sales of passenger cars with combined driving assistance functions exceeded 2.88 million, and the penetration rate rose to 32.4%, a year-on-year increase of 46.2%.
Breakthroughs have been made in key technologies such as a new generation of electronic and electrical architecture, automotive operating systems, computing chips with large computing power, and lidar.
More than 7,000 kilometers of test roads at all levels have been opened nationwide, and the actual road test mileage has exceeded 15 million kilometers. In the test demonstration area and related pilot cities, more than 3,500 kilometers of roads have been upgraded and transformed, and more than 4,000 roadside networking equipment has been installed.
"The research and industrialization of key technologies for intelligent networked vehicles in my country has made great progress, especially the research and development of key technologies is in the global stage." Li Jun, academician of the Chinese Academy of Engineering and chairman of the Chinese Society of Automotive Engineers, believes that at present, China has formed a A relatively complete ICV technology chain.
With the cross-border integration and collaborative innovation of automobiles and electronics, software, communications, artificial intelligence, big data and other industries, China's intelligent networked vehicles have gradually formed a three-dimensional mesh ecosystem covering "vehicles, roads, and clouds".
In addition, breakthroughs have been made in independent research and development of key technologies such as lidar, algorithms, AI chips, smart cockpits, and Beidou positioning, and some products have achieved mass production applications, which strongly supports the development of China's intelligent networked vehicles.
Wider application scenarios
Meet the diverse needs of users
In addition to continuous breakthroughs in technology, the application scenarios of intelligent networked vehicles are also more diverse.
"Near my home, I often see unmanned food delivery vehicles, which is quite interesting." At the exhibition, Ms. Chen, who lives in Shunyi District, Beijing, stopped in front of Meituan's booth and carefully looked at one smaller than her home. The sedan is a slightly smaller, yellow and black car.
In recent years, unmanned delivery is becoming a new trend as consumers’ demand for instant delivery increases.
Intelligent and connected vehicles are promising in this field.
"In February 2020, this automatic delivery truck landed in Shunyi, mainly to provide users with fresh food delivery. It can deliver goods to the downstairs of residential units, with a one-time load of up to 150 kilograms." The staff of the exhibition area introduced to the audience, After the delivery vehicle is automatically parked at the designated location, the user only needs to click on the small screen on the side of the vehicle body and enter the pickup information, and the compartment door will open upwards; after the user picks up the goods, the vehicle will automatically drive away.
"At present, its distribution range covers more than 50 communities in Shunyi, as well as more than 30 public places such as hospitals, shopping malls, industrial parks, etc. In the past two years of regular operation, the automatic distribution vehicles have delivered more than 2.4 million orders. The cumulative driving test mileage exceeds 1.5 million kilometers, and the autonomous driving mileage accounts for more than 97%.”
After watching the demonstration, Ms. Chen told reporters that this new delivery method can save manpower and is very convenient. She hopes that she can actually experience it next time she orders takeout.
However, according to Xia Huaxia, general manager of Meituan's automatic vehicle distribution department, the realization of large-scale automatic distribution still requires further technological maturity.
Compared with other self-driving vehicles, automatic delivery vehicles are mainly used in traffic scenarios of 3 kilometers at the end of the city, and need to face more types of obstacles and more complex traffic interaction scenarios.
For example, the roads in some communities are full of vehicles parked on both sides, and the routes for automatic delivery vehicles are very narrow; there will be many elderly people and children in the community, and automatic delivery vehicles need to be more sensitive to avoid.
"This puts forward extremely high requirements for the automatic distribution system's predictive ability, human-computer interaction ability, 'vehicle, road, cloud' coordination ability, unexpected scene response ability and safety ability." Xia Huaxia believes that to achieve automatic The large-scale commercialization of delivery vehicles requires the joint efforts of the entire industry chain.
In addition to unmanned distribution, the application of intelligent networked vehicles in trunk logistics is also developing rapidly.
Foton Motor exhibited a heavy-duty truck with a height of more than 3 meters and a silver-gray body, which was very eye-catching.
The car's cab is equipped with lidars on both sides, and 7 cameras are hidden around the body.
According to the staff, this intelligent driving heavy-duty truck is mainly used for trunk logistics and can be used in highways, ports, mines, logistics parks and other scenarios. , the vehicle can autonomously decide all driving operations.
"I have seen unmanned trucks transporting goods in some ports, and I feel that intelligent networked vehicles have a broad application space in the field of logistics." Visitor Zhu Haitao told reporters that he usually pays close attention to the dynamics of the intelligent networked vehicle industry. When viewing the exhibition, the most interesting products are smart logistics related products.
"Areas such as ports and logistics parks are closed roads, which makes it easier to control risks, and it is easier for autonomous vehicles to land. After new technologies and new products are put into use, it is easier to see economic benefits. So I am very optimistic. The development prospects of smart logistics in the next few years." Zhu Haitao said.
"In order to support efficient logistics transportation and industrial chain supply, the current logistics industry is actively applying intelligent networking technology, and it has developed from past exploration attempts to today's urgent needs." Liu, Deputy Dean of Tsinghua University Internet Industry Research Institute Dacheng pointed out that from intelligent sorting robots in warehousing, to the Internet of Vehicles of logistics and transportation vehicles, to the automatic distribution of terminals, intelligent network connection has greatly improved the operation efficiency of the logistics industry.
"Low-cost, high-efficiency, convenience, and intelligence have become new trends in the development of the logistics industry, and this change is increasingly common in intelligent transportation scenarios."
Vehicle-network collaboration is becoming more and more mature
Security issues should not be underestimated
For intelligent networked vehicles, only "connection" can be achieved with "network".
At this conference, providers of network services also brought their latest achievements in the field of smart transportation.
In the China Mobile exhibition area, the reporter first noticed some small metal boxes with antennas.
"These modules can be installed on the roadside and the vehicle respectively to transmit and receive signals, and then through the cloud control platform to achieve vehicle-road coordination." According to the staff, using these signal receiving devices, the vehicle can obtain the position, For information such as road congestion level and signal light conditions, the perception delay is millisecond level.
At present, China Mobile has participated in the infrastructure construction of the National Vehicle Network Pilot Zone in Wuxi, Jiangsu Province and the National Vehicle Network Pilot Zone in Chongqing (Liangjiang New Area).
In Wuxi alone, more than 100,000 vehicles have been installed with on-board signal devices.
If the cloud control platform enables the "car" and "road" to realize the information exchange, then the car networking card is to help the "car" and "people" to have better interaction.
"The car networking card can be understood as the SIM card (user identification card) inserted in the car. With this card, the intelligent network car can interact with you like a mobile phone." The staff in the exhibition area gave an example to reporters, such as parking the car. On the side of the road, you can send a text message to it remotely to start the car; if the vehicle encounters an emergency, you can call the rescue center through the voice system.
On the other side of the exhibition area, a staff member used the remote control to operate a car to move back and forth. At the same time, a red line appeared on the display next to it, which accurately marked the moving route of the car.
"The indoor Beidou high-precision positioning system is shown here." The staff told reporters that generally in the indoor environment of the exhibition hall, vehicles cannot receive Beidou positioning signals.
However, a set of indoor positioning equipment was installed on the beam at the site - it looked like several white, round "mushroom heads", which helped the car achieve real-time precise positioning.
"In real life, many people have encountered such a scene - when the car enters the highway tunnel, the mobile phone map indicates that the navigation signal is weak. If this indoor positioning system is installed in the tunnel, such problems will be solved. ." the staff member said.
Safety issues are the key points that cannot be ignored in the development of intelligent networked vehicles.
This includes not only the functional safety of vehicle driving, but also the information security and data security of the vehicle.
The Ministry of Public Security has focused on issues such as self-driving cars on the road for road testing and liability for illegal accidents, actively promoted the improvement and revision of the "Road Traffic Safety Law", and promoted the preparation of 10 technical standards for the "National IoV Industry Standard System Guidelines (Intelligent Vehicle Management)". The development of intelligent and connected vehicles creates a good environment for regulations and standards.
Last year, the Ministry of Industry and Information Technology issued the "Opinions on Strengthening the Access Management of Intelligent and Connected Vehicle Manufacturers and Products", which requires strengthening the management of vehicle data security, network security, software upgrades, functional safety and expected functional safety.
Recently, the Ministry of Industry and Information Technology issued the "Guidelines for the Construction of the National Internet of Vehicles Industry Standard System (Intelligent Connected Vehicles) (2022 Edition)" (Draft for Comment), proposing to formulate and revise more than 100 standards related to ICVs by 2025 , and run through functional safety, expected functional safety, network security and data security and other security standards to meet the standardization needs of intelligent networked vehicle technology, industrial development and government management.
At this conference, Zhang Guangming, deputy director of the Cyber Security Administration of the Ministry of Industry and Information Technology, said that the Ministry of Industry and Information Technology promotes the construction of a security situational awareness platform for the Internet of Vehicles, strengthens the prevention and response to security risks of the Internet of Vehicles, and creates a network security threat of the Ministry of Industry and Information Technology. And the vulnerability information sharing platform, build a professional library of car networking security vulnerabilities, and establish a monitoring notification and collaborative disposal mechanism with key enterprises in the industry chain.
In addition, it also guided the establishment of a security trust and management platform of the Ministry of Industry and Information Technology, realized the mutual recognition and communication of different vehicle-to-vehicle certificate management systems, organized the pilot work of vehicle-to-vehicle identity authentication and security trust, and supported nearly 300 industrial chain entities to jointly develop Technological research, and promote the integration and development of related industries and technologies.
"Breaking through the key technologies of intelligent networked vehicle safety requires the cooperation of government, industry, academia, research, and application under the leadership of the government." Li Jun said that in the face of new security challenges, only the functional safety of intelligent networked vehicles must be highly valued , functional safety and information security are expected to make China's intelligent networked vehicles the safest cars in the world.
