The application relates to a motor vehicle brake lining loss monitoring system, the motor vehicle comprising: a brake device acting on a wheel, the brake device having a lining that is non-rotatable relative to the wheel but is linearly movable parallel to a rotational axis of the wheel; the brake piston can drive the friction plate to move; and an electronic parking brake or an electronic mechanical brake having a drive motor and a piston driving member driven by the drive motor to move linearly, the method comprising: after the motor vehicle is parked, operating the drive motor to move the piston driving member to a predetermined reference position; the driving motor is operated again, so that the piston driving piece moves from the reference position to a stopping position where the piston driving piece makes contact with the braking piston, and the stopping position corresponds to the parking braking position of the braking piston; determining the distance between the reference position and the stop position; and comparing the determined distance with a predetermined reference distance to determine the wear thickness of the friction plate to be measured.
本申请涉及机动车制动摩擦片损耗监测系统,机动车包括:作用于车轮的制动装置,其具有相对于车轮不可旋转但能够平行于车轮的旋转轴线直线移动的摩擦片;能够驱动所述摩擦片移动的制动活塞;以及电子驻车制动器或电子机械制动器,其具有驱动电机以及所述驱动电机驱动而能够直线移动的活塞驱动件,所述方法包括:在机动车驻车后,操作驱动电机以令活塞驱动件移动至事先规定的基准位置;再次操作驱动电机,以使得活塞驱动件从基准位置移动到其与所述制动活塞接触的停止位置,停止位置与制动活塞的驻车制动位置对应;确定基准位置与停止位置之间的距离;将所确定的距离与事先确定的基准距离进行比较,以确定被测摩擦片的磨损厚度。
