China's in vehicle radar industry

The deep integration of China's in vehicle radar industry with 5G in the past decade is driving the perception system from 'single vehicle intelligence' to a new paradigm of 'vehicle road cloud collaboration'. The high bandwidth (peak over 1Gbps) and ultra-low latency (1-5ms) characteristics of 5G enable the real-time transmission of massive point cloud data from 77GHz millimeter wave radar and LiDAR to roadside units and the cloud, supporting accurate decision-making in V2X scenarios. In national level vehicle networking pilot zones such as Liuzhou and Hangzhou, laser radar and millimeter wave radar deployed on the roadside achieve 360 ° global perception through 5G private networks, dynamically warning of blind spot collisions, sudden braking of vehicles and pedestrian intrusion, and reducing accident response time to 0.3 seconds. Huawei, SenseTime and other companies have taken the lead in mass producing 4D imaging radars, combined with 5G-V2X modules, to achieve the integration of 'perception communication decision-making'. The single radar point cloud density has been increased by 5 times, and the detection range has reached over 200 meters. At the national level, the 'Interim Regulations on the Management of Automotive Radar Radio' clarify the usage standards for the 76-79GHz frequency band, and GB/T 45500-2025 'National Standard for Vehicle mounted Lidar' unifies 18 core indicators such as ranging accuracy and anti-interference for the first time. Jiangsu and other regions have introduced specifications for vehicle networking data exchange interfaces to promote standardization of radar data formats. The industry is shifting from 'sensor supply' to 'perception network construction', and 5G has become the nerve center of vehicle road collaboration, reshaping the underlying architecture of intelligent transportation.
