The invention provides an electronic parking brake system and a control method thereof. An electronic parking brake system includes: a piston provided to pressurize a pair of brake pads disposed on both sides of a brake disc that rotates together with wheels of a vehicle; a nut member provided as a pressurizing piston; a spindle member configured to move the nut member; an electric motor provided to rotate the spindle member; and a control unit electrically connected to the electric motor, in which the control unit identifies whether the requested parking execution is an initial parking execution, estimates a motor temperature based on a voltage drop amount of the electric motor, and estimates a locking force required for parking based on the motor temperature if the requested parking execution is not the initial parking execution, and controls the parking of the electric motor. And under the condition that the locking force reaches the target locking force, parking execution is ended.

    本发明提供电子驻车制动系统及其控制方法。电子驻车制动系统包括:活塞,其设置为加压一对刹车片,一对刹车片配置在与车辆的轮子一起旋转的制动盘的两侧;螺母部件,其设置为加压活塞;主轴部件,其设置为移动螺母部件;电动马达,其设置为旋转主轴部件;以及控制部,其与电动马达电连接,其中,控制部识别请求的驻车执行是否为初始驻车执行,在不是初始驻车执行的情况下,根据电动马达的电压下降量估计马达温度,并且根据马达温度估计驻车所需的锁紧力,在锁紧力达到目标锁紧力的情况下,结束驻车执行。
