From September 16th to 19th, the 2022 World Intelligent Connected Automobile Conference and China International New Energy and Smart Connected Auto Exhibition were held in Beijing. At the expo, the forefront technology and intelligent achievements of the global intelligent connected automotive field were "gathered". Among them, car road collaboration and "car cloud integration" technology is shining.

"Smart car" drove into the "Wisdom Road"

"There are accident vehicles 200 meters in front, please slow down and slow down." "Emergency brake in front of the vehicle, please enter the left lane." The Scholars' Highway Simulation scene attracted the attention of reporters.

Fan Ju, Assistant General Manager of Datang Gaohong Zhilian, introduced: "On the car end, we deploy smart car terminals (OBU) to communicate vehicle information and brakes, turns and other driving intentions such as speed, fault conditions, etc. Vehicles and roads. On the side of the road, we installed a series of equipment such as sensors and edge computing units such as the road side communication equipment (RSU), vision and radar to broadcast the perceived vehicles and road status to the vehicle. Interconnection and vehicle roads. In this way, when the vehicle encounters traffic lights, pedestrians crossing the road, and the rear vehicle transformer, the vehicle terminal can issue early warnings and issue relevant prompts such as obstacles, lane changes, and emergency brakes to the vehicle. "

Wanji Technology uses technologies such as three -dimensional modeling, time and space synchronization, and intelligent identification of vehicle characteristics of real scenes to give a relatively complete "holographic intersection solution". The system can realize functions such as the holographic situation, research and judgment analysis, signal adaptive optimization, and multi -dimensional information release of the intersection. The relevant person in charge of Wanji Technology said: "Car road collaboration can provide autonomous vehicles with the" God Perspective "that cannot be achieved by autonomous vehicles, and enhances its ability to integrate the transcendence. Will be safer and more convenient. "

Li Zhenyu, senior vice president of Baidu Group and general manager of the group group of the Intelligent Driving Division, said that the collaboration of vehicle roads can make transportation more efficient. Red and green lights can intelligently adjust the duration according to the actual traffic and flow of people to achieve different smooth travel. This may provide a solution for urban traffic congestion.

Data security is the focus of car road collaboration. How to share information on the premise of ensuring data security? Qi Anxin Car Road collaborative safety protection products bring a solution. According to the relevant person in charge of Qi Anxin, Qi Anxin Car Road Cooperation Security "sentinel" adopts information security technologies such as asset management, vulnerability scanning, vulnerability protection, etc., and can timely discover the vulnerabilities of car road collaborative networks and car end servers, and conduct early warning , To protect the information of RUS, radar, and cameras from leakage or attack.

"Car-Road-Cloud-Net-Picture" reconstruct future traffic

A self -driving car was parked at the intersection and was rearred by the social vehicle driven by the rear. The cause of the accident was determined that the rear vehicle did not maintain a safety accident with the front car. In the exhibition area of the high -level autonomous driving demonstration area in Beijing, the reporter learned that the cloud control platform of the demonstration area through the combination of marginal clouds, regional clouds, and central clouds to achieve real -time safety supervision of internal network testing intelligent driving vehicles. "The cloud control platform can also determine the category of the accident through the" restore "accident process." The relevant person in charge of the exhibition area introduced.

It is understood that the cloud control platform is the core center of the intelligent connected automotive industry infrastructure. It undertakes key tasks such as the collection of big data, data security control, abnormal behavior monitoring and early warning, and intelligent connected car empowerment. "The cloud control platform can analyze the basic information such as vehicle driving and driver status, and evaluate the autonomous driving capabilities of related enterprises and the entire demonstration area, so that the data is more valuable." The person in charge said.

High -precision maps and high -precision positioning have also created new conditions for intelligent connected cars. The relevant person in charge of China Mobile introduced to the China Electronics News reporter that China Mobile uses "5G+Beidou Satellite" as a carrier to integrate new generation of information technologies such as artificial intelligence, the Internet of Things, cloud computing, and big data to achieve static millimeters and dynamic centimeters. Level positioning. The system can also break through the limitations of satellite positioning and achieve full -time global integration positioning.

"Traffic travel is experiencing major changes in a century, and autonomous innovative technologies such as autonomous driving and vehicle road collaboration are further reconstructioning future cars, future transportation and future cities. We believe that the construction of intelligent networking infrastructure is like The construction of subways ten years ago and 5G five years ago will become an important symbol of the comprehensive competitiveness of the city. "Li Zhenyu said.
