The invention belongs to the technical field of vehicle braking, and relates to a braking system suitable for an automatic driving vehicle, the braking system comprises an EBS + ESC controller, an ABS controller and an EPB module, the whole vehicle controller is provided with a three-way solenoid valve and an AEB relay valve, two bi-pass check valves are respectively provided with a service braking air chamber and a composite braking air chamber, and the two bi-pass check valves are connected with the EBS + ESC controller. According to the invention, the parking request is sent to the EPB system through the message by the vehicle control unit; at the moment, an exhaust electromagnetic valve in the EPB module is opened, and an air outlet and an exhaust port of the EPB module are communicated. Compressed air in a parking cavity of the rear axle composite brake chamber is exhausted from an exhaust port of the EPB module. A parking cavity spring pushes an air chamber push rod to drive a brake adjusting arm to generate parking braking force, a brake system has redundant service braking and redundant parking braking schemes when a brake-by-wire system fails, the redundant service braking has an anti-lock function, and the redundant parking braking scheme has an anti-lock function when the brake-by-wire system fails. The redundant service braking system and the redundant parking braking system are matched with the whole vehicle controller to have the fault self-checking capacity and can be used for automatically driving the truck.

    本发明属于车辆制动技术领域的一种适用于自动驾驶车辆的制动系统,包括EBS+ESC控制器、ABS控制器和EPB模块,所述整车控制器安装有三通电磁阀和AEB继动阀,两个所述双通单向阀分别安装有行车制动气室和复合制动气室,本发明通过整车控制器通过报文向EPB系统发送驻车请求。此时EPB模块内部排气电磁阀打开,EPB模块出气口和排气口导通。后桥复合制动气室驻车腔内压缩空气从EPB模块排气口排出。驻车腔弹簧推动气室推杆,驱动制动调整臂产生驻车制动力,制动系统具有线控制动系统失效时的冗余行车制动和冗余驻车制动方案,冗余行车制动具备防抱死功能,冗余行车制动系统和冗余驻车制动系统配合整车控制器具备故障自检能力,可用于自动驾驶卡车。
