The invention discloses a vehicle braking system with a redundancy control function, which is provided with an electromagnetic valve, and the electromagnetic valve controls an execution device of the vehicle braking system; the electromagnetic valve is provided with two electromagnetic valve coils which are an electromagnetic valve main coil controlled by the main service braking unit and an electromagnetic valve backup coil controlled by the backup service braking unit respectively. The invention further discloses a control method of the vehicle braking system. By the adoption of the technical scheme, when the main service braking control unit has an electrical fault, the backup service braking unit controls the electromagnetic valve of the hydraulic loop in a redundant mode to achieve normal service braking; according to the technical scheme, in the automatic driving process of the vehicle, even if the main service braking unit is in electrical failure, conventional service braking without affecting the feeling of a driver can be achieved, and the driving safety performance of the vehicle is improved.
本发明公开了一种具备冗余控制功能的车辆制动系统,设有一个电磁阀,电磁阀控制车辆制动系统的执行器件;电磁阀设置两个电磁阀线圈,分别为由主行车制动单元控制的电磁阀主线圈,以及由备份行车制动单元控制的电磁阀备份线圈。本发明还公开了该车辆制动系统的控制方法。采用上述技术方案,能够在主行车制动控制单元出现电气故障时,由备份行车制动单元冗余控制液压回路的电磁阀实现正常的行车制动;可以保证车辆在自动驾驶过程中,即使主行车制动单元发生电气失效,也能够实现不影响驾驶员感觉下的常规行车制动,提高车辆的行车安全性能。
