The invention discloses a P-gear linkage EPB control system of a pure electric vehicle. The pure electric vehicle comprises an ABS control unit, a vehicle body CAN bus and an EPB control unit. The P-gear linkage EPB control system is provided with an EPB actuating mechanism; and the EPB control unit is respectively connected with the vehicle body CAN bus and the EPB actuating mechanism through thecommunication circuit. The invention further discloses a control method of the control system. By the adoption of the technical scheme, the EPB system detects that a driver selects to switch into theP gear, safety protection is automatically provided for parking of the vehicle, what is guaranteed is that the vehicle has no slope sliding risk under the condition that a P gear mechanism is not involved at all, and the safety performance of the vehicle is improved; the P-gear mechanism is simplified, a P-gear locking mechanism can be omitted due to the arrangement of the whole vehicle, and thelight weight of the whole vehicle is achieved while the cost of the whole vehicle is effectively reduced.

    本发明公开了一种纯电动汽车的P挡联动EPB控制系统,所述的纯电动汽车包括ABS控制单元、车身CAN总线、EPB控制单元;所述的P挡联动EPB控制系统设置EPB执行机构;所述的EPB控制单元分别通过通信电路与车身CAN总线、EPB执行机构相连接。本发明还公开了该控制系统的控制方法。采用上述技术方案,EPB系统检测到驾驶员选择切入P挡,自动为车辆停驻提供安全保护,在完全不需要P挡机构介入的情况下,保障车辆无溜坡风险,提升车辆安全性能;P挡机构简化,整车布置可以节省P挡锁止机构,在有效降低整车成本的同时,实现整车的轻量化。
