Science and Technology Observation of the Service and Trade Association: Intelligent Connected Motors drove to the future

Xinhua News Agency, Beijing, September 3 (Reporter Zhang Manzi) At the 2022 China International Service Trade Fair, the 128 -line laser radar, holographic intersection, smart cockpit and other "black technology" showed China's intelligent connected car field New trends, new breakthroughs.

"As the" eye "of intelligent connected cars, lidar has become the core sensor for the development of cars to high -end autonomous driving." Wang Xuezi, executive deputy general manager of Wanji Technology Automobile Electronic Products Division, introduced that compared with traditional millimeter waves and visual vision For sensors such as identification, laser radar can achieve more accurate perception of targets in strong light, night, and high -speed driving environment.

The latest data from the Ministry of Industry and Information Technology shows that in 2021, the penetration rate of China's L2 -level auxiliary driving passenger vehicle market reached 23.5%, and its penetration rate increased to 30%in the first half of 2022. China's open road test mileage has exceeded 5,000 kilometers. With the support of the policy, the breakthrough of innovative technologies accelerate the advancement of intelligent connected cars.

Once the mixed solid -state 128 vehicle -level laser radar appeared, it attracted the attention of many on -site practitioners. "This laser radar has a maximum of 200 meters, a 0.2 -degree angle resolution, and the scanning frequency of 20 Hz, which can ensure that the vehicle has sufficient reaction time and braking distance under high -speed conditions. Wait for traffic participants and obstacles to accurately identify. "Wang Xuesi said.

With the "smart road", the "wisdom car" can be stable and far away. The innovation breakthrough of intelligent road side technology was also displayed at the service trade association. Sun Yafu, vice president of Qianfang Science and Technology, told reporters: "We deployed perceptual units including visual perception unit, millimeter wave radar, and thunderbolt equipment on the side of the road, communication unit, signal control unit, display unit, edge computing unit Wait, to enhance the "perception" of the road. "

Based on the reality of transportation in my country, Chinese technology companies use holographic base stations, centimeter -level high -precision maps, real scenes of three -dimensional modeling, vehicle characteristics intelligent identification and other technologies to give a relatively complete "holographic intersection solution".

The "holographic intersection solution" created by Chinese technology companies appeared at the service trade meeting.

"By building a new type of perception infrastructure at the intersection, we conducted research and analysis of the traffic operation status of the intersection, and an evaluation indicator of the traffic situation of the output intersection. Provide a basis for the purpose of improving the intersection efficiency, standardizing the order of the intersection, and ensuring the safety of travel, and can solve the technical difficulties of autonomous driving in the city's hybrid traffic flow fields, and provide support for the large -scale landing of autonomous driving in the future. " Zhou Hao, chief engineer of the Technology Intelligent Networking Division, said.

Intelligent connected cars not only need "smart cars" and "wisdom roads", but also "collaborative clouds". The reporter came to the Amazon cloud technology booth and experienced the fun of smart driving.

According to Gu Fan, the general manager of the strategic business development department of Amazon Cloud Technology Greater China, combined with the development path of the coordinated vehicle and roads in my country, interaction between people and vehicles and between vehicles require large -scale data processing and intelligent operations. "Based on cloud services such as computing, storage, data analysis, the Internet of Things, artificial intelligence and machine learning to help car companies collect, process and analyze massive data such as vehicle information, and support multiple IoT devices to access. The model of the car company is implemented on the ground. "

From the perspective of Liangdao Intelligent Founder, compared with other countries, China's intelligent connected car development advantages are significant. On the one hand, my country's intelligent connected automotive technology chain is relatively complete, technological iterations, and rapid production of front -loading, independent research and development of lidar, AI chips, smart cockpit and other technologies have been accelerated to make breakthroughs. Some products have achieved previous mass production applications. On the other hand, the integration and innovation of multiple industries promotes the formation of a three -dimensional mesh ecosystem combining smart transportation and smart cities.
