The invention discloses an electronic mechanical brake redundancy system and a vehicle, the system comprises a main electronic control unit ECU, an auxiliary electronic control unit ECU, a foot feeling simulator and two or four groups of brake redundancy devices, and each group of brake redundancy device comprises an isolating valve and a hydraulic brake. By arranging the brake redundancy devices, when brake failure occurs, the main ECU or the auxiliary ECU can control the isolation valves in the brake redundancy devices to be opened, the hydraulic brakes in the brake redundancy devices extrude the corresponding brake discs to generate brake force, the risk of brake failure of the whole vehicle is avoided, and the safety of the vehicle is improved.
本发明公开一种电子机械制动冗余系统及车辆,该系统包括:主电子控制单元ECU、辅电子控制单元ECU、脚感模拟器、两组或者四组制动冗余装置,其中,每组制动冗余装置包括一个隔离阀和一个液压制动器。本发明通过设置制动冗余装置的方式,使得在发生制动失效时,主ECU或者辅ECU可以控制各组制动冗余装置中的隔离阀打开,各组制动冗余装置中的液压制动器挤压相应的制动盘产生制动力,避免整车出现制动失效的风险,提高车辆的安全性。
