The invention belongs to the technical field of vehicle braking, and particularly provides a main-trailer coordinated braking system and method.The main-trailer coordinated braking system comprises a main vehicle braking subsystem, a trailer braking subsystem and an ECU, and the trailer braking subsystem and the ECU are both connected with the main vehicle braking subsystem; the main vehicle braking subsystem comprises an air processing unit, a parking air storage cylinder, a trailer control valve, a pressure electromagnetic valve, an air pressure sensor, a braking main valve, a braking pedal, a trailer energy supply pipeline and a trailer control pipeline. The pneumatic control type braking signal can skip a gas path from the braking main valve to the trailer control valve, and the gas pressure building time and the pipeline consumption time are greatly shortened; and the pressure electromagnetic valve is an electric control element, the response time is extremely short, the braking response time of the trailer can be remarkably shortened, the braking consistency of the main suspension is improved, and the braking coordination of the main suspension is improved.

    本发明属于车辆制动技术领域,具体提供一种主挂协调制动系统及方法,包括主车制动子系统、挂车制动子系统和ECU,挂车制动子系统和ECU均与主车制动子系统连接;主车制动子系统包括空气处理单元、驻车储气筒、挂车控制阀、压力电磁阀、气压传感器、制动总阀、制动踏板、挂车供能管路和挂车控制管路;本发明的气控式制动信号可跳过制动总阀至挂车控制阀的气路,大幅缩短气压建压时间和管路消耗时间;且压力电磁阀为电控元件,响应时间极短,可显著缩短挂车制动响应时间,使得主挂制动一致性得到改善,提高了主挂制动协调性。
