The invention relates to a dual-redundancy control system and method for a vehicle and an automatic driving vehicle. The dual-redundancy control system comprises a main control unit, an auxiliary control unit and a power system. The main control unit and the auxiliary control unit are connected with each other through a bidirectional heartbeat line, periodically exchange heartbeat signals and check signal integrity so as to monitor real-time state information of the opposite side. The power system is connected with the main control unit and the auxiliary control unit through a first power channel and a second power channel of the vehicle, and the main control unit and the auxiliary control unit are connected with an action execution system of the vehicle. When a power supply, a control unit and a sensor of the vehicle have a single-point fault, the design of the dual-redundancy control system covering the whole link can ensure normal operation of system functions, and the safety and robustness of the vehicle during driving are improved.
本申请涉及一种车辆的双冗余控制系统、控制方法及自动驾驶车辆,该系统包括主控单元、副控单元及电源系统。主控单元与副控单元通过双向心跳线相互连接,周期性交换心跳信号并校验信号完整性,以监测对方的实时状态信息。电源系统通过车辆的第一电源通道与第二电源通道分别连接主控单元与副控单元,主控单元与副控单元分别连接车辆的动作执行系统。当车辆的电源、控制单元以及传感器出现单点故障时,这样覆盖全链路的双冗余控制系统设计能够确保系统功能正常运行,提升了车辆行驶时的安全性与鲁棒性。
