The invention discloses a manual removing auxiliary system and method for an electronic parking braking fault. The system comprises an automobile ECU, a parking braking motor driving control module, a parking braking detection module, an electronic braking box body, a motor, a reduction gear set, a driving screw rod, a piston, a caliper assembly and a manual removing mechanism, wherein the motor, the reduction gear set, the driving screw rod, the piston, the caliper assembly and the manual removing mechanism are arranged in the electronic braking box body. When a fault occurs, the parking braking detection module sends a fault signal to an automobile ECU, the parking braking motor driving control module is controlled to release the locking state of the motor, the reduction gear set can rotate freely, a driver uses a vehicle-mounted tool to enable the manual release mechanism to be connected with the reduction gear set, and the vehicle-mounted tool is driven to rotate freely. An external tool is screwed to drive the manual releasing mechanism to rotate, the driving screw drives the piston to move backwards, the caliper assembly releases the holding action on the brake disc to enable the vehicle to enter a limp mode, a driver can drive the vehicle to a maintenance factory for maintenance, the situation that the vehicle stops on a road and disturbs traffic is avoided, and meanwhile the trailer cost is saved.

    本发明公开了一种电子驻车制动故障的手动解除辅助系统及方法,该系统包括汽车ECU、驻车制动电机驱动控制模块、驻车制动检测模块、电子制动箱体,以及设于电子制动箱体内的电机、减速齿轮组、驱动螺杆、活塞、卡钳组件和手动解除机构。出现故障时,驻车制动检测模块发送故障信号至汽车ECU,控制驻车制动电机驱动控制模块对电机的锁定状态进行解除,使减速齿轮组可自由转动,驾驶人员采用车载工具使手动解除机构与减速齿轮组衔接,拧动外部工具带动手动解除机构旋转,使驱动螺杆带动活塞向后位移,卡钳组件解除对制动盘的抱紧动作使车辆进入跛行模式,驾驶人员可将车辆开往维修厂进行维修,避免停在道路上对交通造成干扰,同时也节约了拖车费用。
