The invention belongs to the technical field of vehicle braking, and particularly provides a lifting vehicle type rear axle braking control system and method.The system comprises an EBS bridge module, a two-position three-way electromagnetic valve, a two-way low-selection valve and an EBS electronic control unit, and the EBS bridge module is directly connected with a driving axle braking driving cavity; the two-position three-way electromagnetic valve and the EBS bridge module are connected with a left brake driving cavity and a right brake driving cavity of a lifting bridge through the two two-way low-selection valves, and the EBS electric control unit is connected with the EBS bridge module and the two-position three-way electromagnetic valve. Two two-way low-selection valves and a two-position three-way electromagnetic valve are added to replace a six-channel EBS control system, the problem of dragging of a lifting axle can be solved when a driving wheel slips to activate the ASR function, tire abrasion is reduced, and the braking performance is improved.
本发明属于车辆制动技术领域,具体提供一种提升车型后桥制动控制系统及方法,所述系统包括EBS桥模块、两位三通电磁阀、双通低选阀和EBS电控单元,EBS桥模块直接连接驱动桥制动行车腔,两位三通电磁阀与EBS桥模块通过两个双通低选阀连接有提升桥的左右两路制动行车腔,EBS电控单元连接有EBS桥模块和两位三通电磁阀。通过增加两个双通低选阀和一个两位三通电磁阀代替六通道EBS控制系统,在驱动轮打滑激活ASR功能时可以解决提升桥拖曳问题,减少降低轮胎磨损,提高制动性能。
