The invention relates to the field of automobiles, in particular to a vehicle braking and parking backup system and a parking control method. The system comprises an air storage module which is communicated with an energy storage spring air chamber through an air conveying pipeline, and the energy storage spring air chamber is used for driving a vehicle to execute a parking action; the EPB electromagnetic valve is arranged on the gas conveying pipeline, and the EPB electromagnetic valve is used for cutting off or conducting the gas conveying pipeline; the electric control module is arranged on the gas conveying pipeline, and the electric control module is used for cutting off or conducting the gas conveying pipeline; and the EBS controller is connected with the EPB electromagnetic valve and the electric control module, and the EBS controller is used for detecting the working state of the EPB electromagnetic valve and the working state of the vehicle. Parking is electrically controlled, the EBS controller is adopted to control the electric control module to serve as parking redundant backup in the automatic driving mode, and the reliability is high. Furthermore, according to the scheme, backup is achieved without additionally arranging a controller, and the cost is low.
本申请涉及汽车领域,具体涉及一种车辆制动驻车备份系统及驻车控制方法。其包括:储气模块,其通过输气管路与储能弹簧气室连通,所述储能弹簧气室用于驱使车辆执行驻车动作;EPB电磁阀,其设于所述输气管路上,所述EPB电磁阀用于截止或导通所述输气管路;电控模块,其设于所述输气管路上,所述电控模块用于截止或导通所述输气管路;EBS控制器,其与所述EPB电磁阀和电控模块相连,所述EBS控制器用于检测所述EPB电磁阀和车辆的工作状态。通过采用电气控制驻车,并采用EBS控制器控制电控模块作为自动驾驶模式下的驻车冗余备份,其可靠性较高。进一步地,本方案未额外增加控制器即实现备份,成本较低。
