The invention relates to the technical field of vehicle control, and discloses a friction plate wear detection method, the method is applied to an electronic parking brake system of a vehicle, and the electronic parking brake system comprises a parking motor, a motor push rod and a friction plate; comprising the following steps: detecting a request signal of the electronic parking brake system; detecting the change length of the push rod according to the request signal; calculating the actual wear thickness of the friction plate according to the change length and the maximum allowable length of the motor push rod; and comparing the actual wear thickness of the friction plate with the limit wear thickness so as to control the electronic parking brake system to output a detection signal to a vehicle cabin. By means of the technical scheme, the problems that an alarm reed in a traditional vehicle is inaccurate in brake friction plate loss alarm, and a user cannot find the brake friction plate loss alarm in time can be solved.

    本申请涉及车辆控制技术领域,公开了一种摩擦片磨损检测方法,该方法应用于车辆的电子驻车制动系统,电子驻车制动系统包括驻车电机、电机推杆和摩擦片;包括:检测电子驻车制动系统的请求信号;根据请求信号检测所述推杆的变化长度;根据电机推杆的变化长度和最大允许长度计算摩擦片的实际磨损厚度;将摩擦片的实际磨损厚度与极限磨损厚度进行对比,以控制电子驻车制动系统输出检测信号至车辆座舱。应用本申请的技术方案,能够解决传统车辆中报警簧片对制动摩擦片损耗报警不准确,以及用户不能及时发现制动摩擦片损耗报警的问题。
