The new progress made in the autonomous driving scenario in the vehicle-road coordination system has attracted attention from all parties. Autonomous driving promoted by vehicles and roads breaks through mixed traffic scenarios and plays an important role in dealing with extreme situations.

    A few days ago, Yu Jian, deputy director of the Strategic Planning Department of the Ministry of Science and Technology, came to the national smart transportation demonstration base in Beixiaoying Town, Shunyi District, Beijing, and investigated the new achievements of autonomous driving on the spot. Guiding opinions were put forward for scenes, such as meeting cars, and highly affirmed the systematic technical path.

    Yu Jian said: “The implementation of the autonomous driving solution based on vehicle-road collaboration has successfully verified a highly coordinated global solution for people, vehicles, roads, networks, and clouds, giving full play to the advantages of intelligent transportation systems and efficiently solving vehicle travel. The safety and efficiency issues in the process have a typical industry demonstration effect."

Technology Drives Digital Transformation, Vehicle-Road Collaboration Guides Autonomous Driving to Land

    Technology is an important force driving the digitalization of industries. In February 2020, 11 ministries, commissions, offices, and bureaus including the National Development and Reform Commission and the Ministry of Science and Technology jointly issued the "Smart Car Innovation Development Strategy". The main task is to build a collaborative and open smart car technology innovation system, and breakthrough key basic technologies are The key points include the research and development of basic forward-looking technologies such as complex environment perception, intelligent decision control, and vehicle-road interaction. At the same time, it emphasizes the promotion of intelligent road infrastructure planning and construction, and further clarifies that by 2025, the new generation of automotive wireless communication networks (5G-V2X) will be gradually applied in some cities and highways, so that highly autonomous smart cars will be used in specific Market-oriented application in the environment.

    The technical system of autonomous driving guided by vehicle-road collaboration is a sample of the deep integration of new technologies such as big data, the Internet, artificial intelligence, and supercomputing with the transportation industry.

    According to the introduction of the project leader Mushroom Car Association, the whole solution relies on the two engines of Mushroom OS and AI cloud platform, starting with people, vehicles, roads, networks, and clouds, and integrates vehicle-road collaboration, vehicle-vehicle collaboration, and bicycle intelligence. Three systems of intelligent perception, vehicle-road collaboration and AI cloud have been formed. Among them, the intelligent perception system integrates new-generation technologies such as chips, sensors, Beidou + GPS high-precision positioning, the vehicle-road collaboration system connects cars to roads, and cars to cars through 5G+C-V2X, and AI cloud has big data analysis Decision-making ability, coordinate all traffic elements, global dispatch, and contribute driving strategy.

Coping with mixed traffic scenarios, collaborative integration is the key

    The vehicle-road synergy demonstration-level section investigated by Deputy Director Yu Jian belongs to the national smart transportation demonstration base, with a total length of 7.2 kilometers, including large trucks, cars, non-motor vehicles, pedestrians, and temporary roadblocks. The traffic participants are extremely complicated. It is a typical hybrid road. Mushroom Car Alliance has implemented intelligent upgrades and transformations on 18 intersections in the road section. Based on the vehicle-road coordination system, it connects cars to cars, cars to roads, and cars to the cloud, and coordinates all traffic elements globally. It is precisely because the vehicle-road collaboration is based on the integration of bicycle intelligence that enables autonomous driving to achieve a safer and more efficient landing.

    During the investigation, Mushroom Car Federation demonstrated to Deputy Director Yu Jian the unprotected left turn in the scene of vehicle-road collaborative autonomous driving. There are no traffic lights, stop signs, or traffic police instructions. Turn left without warning to deal with oncoming traffic flows. This is one of the most difficult operations encountered in driving. At the scene, guided by the system of vehicle-road coordination, automatic driving accurately predicts the intentions of all incoming vehicles during the entire left turn, automatically adjusts the route, and drives safely and smoothly.

    It is learned from the Mushroom Vehicle Association that through the integration of vehicle-road collaboration, vehicle-vehicle collaboration, and bicycle intelligence, Mushroom Car OS can obtain redundant perception information from multiple systems to form a 360-degree perception system. The high-precision positioning module of Mushroom Vehicle Alliance supports Beidou satellite navigation and GPS global positioning at the same time, so that the car terminal can obtain accurate position data. The Mushroom Car OS already supports 4G, 5G and C-V2X multiple communication channels to ensure the success rate and readiness of data transmission, and real-time information exchange and decision-making with the AI ​​cloud platform.

    According to the survey, the autonomous driving scheme of vehicle-road collaborative guidance has obvious advantages in complex scenarios such as large trucks meeting cars without marking lines, alternate left-turn traffic, and narrow-lane traffic on mixed sections.

    At present, autonomous driving has two mainstream directions in the world. One is led by bicycle intelligence, and the other is driven by vehicle-road collaboration. 5G, C-V2X, Beidou satellite positioning, cloud computing, and big data provide important technical support for vehicle-road collaborative guided autonomous driving, which will have a positive impact on a new round of global technological innovation and industrial transformation.
