The invention belongs to the technical field of commercial vehicle parts, and particularly relates to a parking redundancy control system for a commercial vehicle drive-by-wire chassis. An air inlet (11) of the EPB valve module (1) is communicated with an air source pipeline (12), the air source pipeline (12) is communicated with an air supply source, a module air outlet (13) of the EPB valve module (1) is communicated with the spring parking control air chamber (3), a module fourth port (14) of the EPB valve module (1) is communicated with an electromagnetic valve second port (21) of the electromagnetic valve (2), and the electromagnetic valve (2) is further provided with an electromagnetic valve third port (22). The parking redundancy control system for the drive-by-wire chassis of the commercial vehicle is simple in structure, when an EPB cannot automatically achieve parking, automatic activation of parking braking is reliably ensured, parking braking is achieved, the emergency parking effect is achieved, safe parking of the vehicle is ensured, and the safety of the vehicle and the safety of drivers and passengers are guaranteed.
本发明属于商用车零部件技术领域,更具体地说,是涉及一种商用车线控底盘用驻车冗余控制系统。EPB阀模块(1)的进气口(11)连通气源管路(12),气源管路(12)连通供气气源,EPB阀模块(1)的模块出气口(13)连通弹簧驻车控制气室(3),EPB阀模块(1)的模块第四口(14)连通电磁阀(2)的电磁阀第二口(21),电磁阀(2)还设置电磁阀第三口(22)。本发明所述的商用车线控底盘用驻车冗余控制系统,结构简单,在EPB无法自动实现驻车时,可靠确保驻车制动自动激活,实现驻车制动,起到应急驻车的作用,确保车辆安全停车,保障车辆安全和驾乘人员安全。
