The invention discloses a redundant braking system supporting complete automatic driving of a commercial vehicle, and belongs to the technical field of commercial vehicle automatic driving. The systemcomprises a main control module, a redundancy control module, a trailer control valve, an air cylinder I, an air reservoir II, an air cylinder III, a first power supply, a second power supply, a first CAN network, a second CAN network, a front axle left brake air chamber, a front axle right brake air chamber, a rear axle left driving air chamber, a rear axle right driving air chamber, a rear axleleft spring parking air chamber and a rear axle right spring parking air chamber, and each wheel of the front axle and the rear axle is respectively provided with two wheel speed sensors; and the main control module and the redundancy control module communicate through an internal CAN network. Safety redundancy is achieved in all aspects of vehicle perception, control and execution, the braking safety requirement of the full-automatic driving technology is met, and the redundant braking system can be widely applied to tractors, cargo trucks and passenger car types such as 4X2 and 6X4 in commercial vehicles.

    本发明公开了一种支持商用车完全自动驾驶的冗余制动系统,属于商用车自动驾驶技术领域,该系统包括主控制模块、冗余控制模块、挂车控制阀、储气筒I、储气筒II、储气筒III、第一电源、第二电源、第一CAN网络、第二CAN网络、前桥左制动气室、前桥右制动气室、后桥左行车气室、后桥右行车气室、后桥左弹簧驻车气室、后桥右弹簧驻车气室、前桥和后桥的各个车轮分别安装有2个轮速传感器;主控制模块和冗余控制模块之间通过内部CAN网络进行通信;本发明从车辆感知、控制和执行全方面实现安全冗余,支持完全自动驾驶技术的制动安全需求,可广泛适用于商用车中的牵引车、载货卡车以及客车车型,如4X2,6X4等。
