A vehicle-road cooperation system based on a 4D millimeter wave radar comprises a 4D millimeter wave radar system unit, a cloud server unit, a road traffic information service unit and a user terminal unit. The 4D millimeter wave radar system unit emits electromagnetic waves and receives target echoes, and vehicle information and road environment information are taken to generate road data; the cloud server unit receives and stores the road data and serves as a platform for processing the road data; the road traffic information service unit judges traffic accidents, extracts road features and identifies abnormal conditions and dangerous driving vehicles on roads to obtain traffic road information data, and the user terminal unit receives the traffic road information data, converts the traffic road information data into a 3D model, displays the 3D model to a driver and provides auxiliary information for an automatic driving system. The system can provide comprehensive road information for related departments, is used for road collaborative management, can provide auxiliary driving data for a driver and an automatic driving system in real time, and improves the driving safety.
