The invention belongs to the technical field of vehicle braking control, and particularly relates to a braking system with auxiliary service braking, which comprises a service braking pipeline and an auxiliary service braking pipeline, one end of the auxiliary service braking pipeline is connected with an air source, and the other end is connected with a control end of a relay valve; a valve group capable of adjusting the air pressure at the control end of the relay valve is arranged on the auxiliary service braking pipeline; and the controller is used for adjusting the valve group according to the detected air pressure at the control end of the relay valve under the set condition, so that the air pressure at the control end of the relay valve reaches the target air pressure under the corresponding set condition. Through the connection mode and the arrangement of the valve bank capable of achieving linear controllable closed-loop adjustment of air pressure, the controller meets the air pressure needed by the brake chamber through the control, the safety of vehicle braking is guaranteed, meanwhile, the situation that the air pressure at the control end of the relay valve is uncontrollable, and the service life of a vehicle is prolonged is avoided. And the brake reliability of the brake system is influenced when the pneumatic brake is too large.

    本发明属于车辆制动控制技术领域,具体涉及一种带有辅助行车制动的制动系统,包括行车制动管路与辅助行车制动管路,辅助行车制动管路一端连接气源,另一端连接继动阀的控制端;辅助行车制动管路上设置有可调节继动阀控制端处气压的阀组;还包括控制器,用于在设定条件下,根据检测得到的继动阀控制端处气压,调节所述阀组,以使继动阀控制端处气压达到对应设定条件下的目标气压。通过上述连接方式,以及设置能够实现能够实现气压的线性可控闭环调节的阀组,控制器通过上述控制,进而满足制动气室所需气压,保证了车辆制动的安全,同时也避免了继动阀控制端处气压不可控,导致气制动过大时影响制动系统制动可靠性的情况。
