The invention discloses an electronic parking redundant system and a control method thereof.The system comprises a parking switch, a first EPB controller, a second EPB controller, a left EPB motor and a right EPB motor, the first EPB controller and the second EPB controller interact through a CAN, the first EPB controller comprises a first control unit and a first H bridge, and the second EPB controller comprises a second control unit and a second H bridge; the first control unit is connected with the parking switch, the first H bridge, the second control unit, the second H bridge, the left EPB motor and the right EPB motor. The second control unit is connected with the parking switch, the first H bridge, the second control unit, the second H bridge, the left EPB motor and the right EPB motor. According to the electronic parking redundant system and the control method thereof, when single nodes of the EPB controllers fail under different conditions, the other effective EPB controller achieves full functions or 100% parking force of the parking system through different control strategies.

    本发明公开了一种电子驻车冗余系统及其控制方法,该系统包括:驻车开关、通过CAN交互的第一EPB控制器和第二EPB控制器、左侧EPB电机和右侧EPB电机,第一EPB控制器包括第一控制单元和第一H桥,第二EPB控制器包括第二控制单元和第二H桥;第一控制单元分别与驻车开关、第一H桥、第二控制单元、第二H桥、左侧EPB电机和右侧EPB电机连接;第二控制单元与驻车开关、第一H桥、第二控制单元、第二H桥、左侧EPB电机和右侧EPB电机连接。本发明提供的电子驻车冗余系统及其控制方法,在EPB控制器不同情况单节点失效时,另一路有效的EPB控制器通过不同控制策略,实现驻车系统的全功能或100%驻车力。
