my country's deployment of unmanned driving infrastructure has started the automotive radar technology experiment

On November 23, the reporter learned from the Automotive Information Service Industry Application Alliance that my country has launched research and testing work on 77-81GHz millimeter wave radar wireless technology and frequency division for vehicles. In addition, the Ministry of Industry and Information Technology commissioned the Automotive Information Service Industry Application Alliance (TIAA) and the China Academy of Information and Communications Technology to carry out research and testing work on LTE-V wireless technology and frequency division for intelligent transportation vehicle-to-vehicle communication based on independent intellectual property rights. All these indicate that China has begun to comprehensively deploy independent vehicle-to-vehicle communication technology based on 5G.

With the industrialization and commercialization of my country's advanced communication technology, it will be beneficial to enhance China's core competitiveness in the field of smart cars and vehicle networking, support China's independent technology to become the core proposal for global frequency unification of intelligent transportation systems at the 2019 World Radiocommunication Conference (WRC-19), and promote Chinese technology to seize the cutting-edge market.

5G-based autonomous vehicle-to-vehicle communication technology is crucial for autonomous and unmanned driving. Specifically, unmanned vehicles need to "see" or "sense" the external environment through sensors before they can automatically plan driving routes and control the vehicle to reach the predetermined destination. In addition, to achieve autonomous driving and even unmanned driving, four weather conditions, simple during the day, complex during the day, simple at night, and complex at night, are required to ensure 100% reliable driving, so communication technology and other technologies are needed.

Pang Chunlin, Secretary General of the In-Vehicle Information Service Industry Application Alliance (TIAA), pointed out that for smart cars and smart transportation, sensors and communication technologies are like the left and right eyes, playing different roles. At present, due to technical reasons, the "left eye" of image sensors, millimeter-wave radars, and laser radars cannot guarantee 100% recognition of targets under all-weather and all-terrain conditions. Therefore, it is necessary to rely on the "right eye" of vehicle-to-vehicle communication technology to supplement it, so that the binocular vision level can reach 1.5.
