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 like, and consequently the vehicle automatic emergency braking system cannot conduct accurate emergency braking are solved.

    本发明涉及智能交通技术领域,尤其涉及一种基于车路协同的车辆紧急制动系统,路侧单元采集道路路况数据,所述道路路况数据包括道路影像数据以及道路影像数据采集终端位置信息,并对采集道路路况数据进行数据预处理,远车车载单元以及本车车载单元之间通信建立数据加密协议,路侧单元、远车车载单元以及本车车载单元通过数据加密单元加密后传输至本车数据分析单元,本车数据分析对数据信息进行分析处理,得到汽车制动指令,完成汽车紧急制动。解决现有的车辆自动紧急制动系统存在使用范围狭窄和传感器复用率低等不足的问题,导致车辆自动紧急制动系统无法准确紧急制动的问题。
