The invention discloses an EMB redundant backup system and a vehicle, the system comprises an EMB ECU, an air spring ECU, a reversing valve and two or four air brakes, and each air brake comprises a brake wheel cylinder and two brake shoes. According to the scheme, when control failure happens to an EMB system, the reversing valve is controlled by the air spring ECU to open the second connector, so that pistons at the two ends in each brake wheel cylinder are pushed to move towards the two ends to push the two corresponding brake shoes to rotate, after the two brake shoes rotate, friction plates can rub disc caps of the corresponding brake discs, and the brake discs are driven to rotate. Therefore, braking force is generated, the vehicle is braked, and the safety of the vehicle is improved.
本发明公开一种EMB冗余备份系统及车辆,该系统包括EMB ECU、空气弹簧ECU、换向阀以及两个或者四个气刹制动器,其中,每个气刹制动器包括制动轮缸和两个制动蹄片。应用本发明的方案,当EMB系统发生控制失效时,通过空气弹簧ECU控制换向阀打开第二接口,从而推动各制动轮缸内的两端活塞向两端运动推动对应的两个制动蹄片旋转,两个制动蹄片旋转后即可通过摩擦片摩擦对应的制动盘的盘帽,从而产生制动力,让车辆制动,提高车辆的安全性。
