The invention discloses a drive-by-wire redundancy brake control system for a heavy-duty vehicle. The drive-by-wire redundancy brake control system comprises an oil supply subsystem, a control valve set and an execution assembly which are sequentially connected through a hydraulic oil way. the control valve set comprises more than two proportional electromagnetic valves and a redundancy control assembly; the execution assembly comprises more than two brake oil cylinders; an output oil port of the oil supply subsystem is simultaneously connected with more than two proportional electromagnetic valves, and the more than two proportional electromagnetic valves are respectively connected with more than two brake oil cylinders through the redundancy control assembly; the redundancy control assembly enables more than one path to be arranged between the oil supply subsystem and the execution assembly in an electric control or hydraulic control mode. According to the fault-tolerant control method, system redundancy and fault-tolerant control can be achieved in an electric control or hydraulic control mode, and the braking function of the vehicle is guaranteed.

    本发明公开了一种重载车辆线控冗余制动操纵系统,包括:通过液压油路依次相连的供油子系统、控制阀组和执行组件;其中,所述控制阀组包括:两个以上比例电磁阀和冗余控制组件;所述执行组件包括:两个以上制动油缸;所述供油子系统的输出油口同时与两个以上比例电磁阀连接,两个以上比例电磁阀通过冗余控制组件分别与两个以上制动油缸连接;所述冗余控制组件以电控或液控的方式使供油子系统与执行组件之间具有一路以上通路;容错控制方法可通过电控或液控方式实现系统冗余和容错控制,保证车辆的制动功能。
