The invention relates to a backup controller of an electronic parking brake system (BC-EPB for short), which is used for the basic function backup of a controller of the electronic parking brake system (EPB for short), and is characterized in that the backup controller of the electronic parking brake system (BC-EPB for short) is used for the basic function backup of the controller of the electronic parking brake system (EPB for short). Comprising a power management module, a communication module, a vehicle signal detection module, an MCU module, a motor driving module and a selective switch module. The BC-EPB can detect an EPB switch and/or a P-gear signal, and whether the EPB motor is controlled or not is selected through the selection switch module. When the EPB controller works normally, the EPB controller can directly control the EPB motor through the selection switch module. When the EPB controller fails, the BC-EPB can take over and control the EPB motor, and parking and releasing functions of the EPB are achieved. Even if the BC-EPB fails, the EPB controller can still directly control the EPB motor through the selection switch module. By the adoption of the technical scheme, basic function backup of the EPB controller can be achieved, a P-gear lock is replaced, parking safety is guaranteed, and the whole vehicle cost is reduced.

    本发明涉及一种电子驻车制动系统备份控制器(Backup Controller of Electrical Parking Brake,以下简称BC‑EPB),用于电子驻车制动系统(Electrical Parking Brake,以下简称EPB)控制器的基本功能备份。包括:电源管理模块、通信模块、车辆信号检测模块、MCU模块、电机驱动模块和选择开关模块。BC‑EPB可以对EPB开关和/或P挡信号进行检测,通过选择开关模块选择是否对EPB电机进行控制。当EPB控制器正常工作时,EPB控制器可以直接通过选择开关模块对EPB电机进行控制。当EPB控制器失效时,BC‑EPB可以接管控制EPB电机,实现EPB的驻车和释放功能。即使BC‑EPB失效时,EPB控制器仍然可以直接通过选择开关模块对EPB电机进行控制。采用上述的技术方案,可以实现EPB控制器的基本功能备份,取代P档锁,保证驻车安全并且降低整车成本。
