The invention discloses an EPB control system of a drum brake parking braking device, which comprises an EPB executing mechanism and a control unit, and is characterized in that the EPB executing mechanism is used for executing a parking braking state or a releasing braking state and acquiring self running state information; the control unit is electrically connected with the wheel speed sensor, the EPB executing mechanism, the vehicle body controller, the storage battery and the EPB switch. The control unit comprises a receiving module, a judging module and an executing module. The invention further discloses a control method which comprises a release control method, a parking control method and a power-on self-test control method. According to the invention, the EPB execution mechanism can obtain the running state of the EPB execution mechanism and feed back the real running state of the EPB execution mechanism to the control unit, so that information obtained by a driver is correct information, and potential safety hazards are avoided; in addition, the control unit performs joint judgment through information in the wheel speed sensor and the EPB executing mechanism so as to ensure that whether the vehicle is successfully parked or not can be correctly judged on the ground at different angles.

    本发明公开了一种鼓式制动器驻车制动装置的EPB控制系统,其包括EPB执行机构和控制单元,EPB执行机构用于执行驻车制动状态或释放制动状态,并获取自身运行状态信息;控制单元与轮速传感器、EPB执行机构、车身控制器、蓄电池和EPB开关电连接,控制单元包括接收模块、判断模块和执行模块;本发明还公开了一种控制方法,其包括释放控制方法、驻车控制方法和上电自检控制方法。本发明中,EPB执行机构能够获取自身运行状态并向控制单元反馈自身真实的运行状态,确保驾驶员得到的信息为正确信息,避免带来安全隐患;另外,控制单元通过轮速传感器和EPB执行机构中的信息共同判断,以确保车辆在不同角度的地面均能够正确判断是否成功驻车。
