The invention provides an electronic parking brake system control strategy. The electronic parking brake system control strategy comprises the steps that light clamping current when a motor executes clamping operation is set in a controller of an electronic parking brake system; the light clamping current is the current of a motor when a friction plate of the parking brake actuator is just in contact with a brake disc; the light clamping current is smaller than the current when the motor clamps but larger than the current when the motor idles; when the parking brake actuator is in a clamping state and a release instruction is received, if the current clamping current of the motor is smaller than the light clamping current, motor braking is executed after the light clamping current is executed, and the release instruction is immediately responded after braking is finished. According to the invention, the working state of the parking brake actuator can be changed in time according to the request instruction of the driver in the action process of the motor, so that the clamping or releasing request of the driver can be quickly responded, and the driving requirement of the driver can be well met.

    本发明提供了一种电子驻车制动系统控制策略,其包括:在电子驻车制动系统的控制器中设定电机在执行夹紧操作时的轻夹电流;所述轻夹电流为驻车制动执行器的摩擦片刚接触到制动盘时电机的电流;所述轻夹电流小于电机夹紧时的电流但大于所述电机空转时的电流;当驻车制动执行器处于正在夹紧状态,在收到释放指令时,若电机的当前夹紧电流小于轻夹电流,则执行至轻夹电流后,而后执行电机制动,制动结束后,立即响应释放指令。本发明能够使得驻车制动执行器,在电机动作的过程中,及时根据驾驶员的请求指令改变工作状态,从而能够较为快速地响应驾驶员的夹紧或释放请求,进而较好地满足驾驶员的驾驶需求。
