The invention discloses a redundant drive-by-wire brake system and method for a commercial vehicle and the vehicle, a main brake system and a sub brake system are adopted to cooperate with a main intelligent driving controller and an auxiliary intelligent driving controller of an automatic driving vehicle, two CAN (Controller Area Network) receive deceleration instructions of the two intelligent driving controllers and execute a brake request of the vehicle, and when one of the systems fails, the main brake system and the sub brake system are switched on. The main braking system and the sub-braking system comprise two independent power supply modules, power supply redundancy is achieved, the main braking system and the sub-braking system are each provided with an independent communication module, when one set of communication goes wrong, the whole vehicle can conduct interaction through signals of the other set of system, and the communication efficiency is improved. The system is simple in design, and can meet the requirement of safe driving of the vehicle after the braking system breaks down.
本发明公开一种商用车冗余线控制动系统、方法及车辆,采用主制动系统与子制动系统,配合自动驾驶车辆的主智驾控制器与辅智驾控制器,两条CAN接收两个智驾控制器的减速度指令,执行车辆的制动请求,在其中一个系统失效时,另一个制动系统执行减速度请求,实现制动冗余,主制动系统与子制动系统包括两个独立的电源模块,实现供电冗余,且主制动系统与子制动系统均有独立的通讯模块,其中一套通讯出现问题,整车可以采用另一套系统的信号进行交互,实现通讯冗余,该系统设计简单,在制动系统出现故障后,能够满足车辆安全行驶的需求。
