description The invention relates to the technical field of intelligent traffic, in particular to a vehicle emergency braking system based on vehicle-road cooperation, which is characterized in that a roadside unit acquires road condition data including road image data and position information of a road image data acquisition terminal, and performs data preprocessing on the acquired road condition data; a data encryption protocol is established between the remote vehicle on-board unit and the vehicle on-board unit in a communication mode, the road side unit, the remote vehicle on-board unit and the vehicle on-board unit are encrypted through the data encryption unit and then transmitted to the vehicle data analysis unit, the vehicle data analysis unit analyzes and processes data information, an automobile braking instruction is obtained, and automobile emergency braking is completed. The problems that an existing vehicle automatic emergency braking system is narrow in application range, low in sensor reuse rate and the l
