The invention belongs to the technical field of vehicle manipulation and control, and particularly relates to a drive-by-wire redundancy braking system with service braking decoupling and parking braking coupling. The system comprises a brake pump source, a brake valve controller, a parking brake proportional valve, a left service brake proportional valve, a right service brake proportional valve, a parking brake pressure sensor, a left service brake pressure sensor, a right service brake pressure sensor, a left brake cylinder and a right brake cylinder. Compared with the prior art, the driving braking decoupling and parking braking coupling drive-by-wire redundancy braking system provided by the invention can ensure the braking safety of the vehicle under the fault condition while realizing the independent control of the brake force drive-by-wire decoupling of the two sides of the vehicle.
本发明属于车辆操纵与控制技术领域,具体涉及一种行车制动解耦驻车制动耦合的线控冗余制动系统,所述系统包括:制动泵源、制动阀控制器、驻车制动比例阀、左行车制动比例阀、右行车制动比例阀、驻车制动压力传感器、左行车制动压力传感器、右行车制动压力传感器、左制动缸以及右制动缸;与现有技术相比较,本发明提供的行车制动解耦驻车制动耦合的线控冗余制动系统能够在实现车辆两侧制动力线控解耦独立控制的同时保证故障情况下车辆的制动安全性。
