    • PURPOSE: A method for warning the wear of a brake pad is provided to prevent an accident due to the defect of a brake pad by making a driver change the brake pad at a proper time. CONSTITUTION: A method for warning the wear of a brake pad comprises the steps of detecting the braking pressure by a pressure sensor(S110), determining a reference deceleration speed of a vehicle corresponding to the braking pressure(S120), detecting the vehicle wheel speed of each vehicle wheel via a vehicle wheel speed sensor(S130), calculating a deceleration speed of the vehicle depending on the rate of change of wheel speed over time(S140), comparing the reference vehicle deceleration speed with the actual vehicle deceleration speed(S150), deciding a brake pad as defective if the actual vehicle deceleration speed is lower than the reference value(S160), deciding the brake pad as defective if the brake pad is decided as defective for many times(S180), and warning a driver of the defect of the brake pad by lighting on a lamp(S190).
    • 目的:提供一种警告刹车片磨损的方法,以防止由于刹车片的缺陷而使驾驶员在适当的时间更换刹车片而导致事故。 构成:用于警告制动衬块磨损的方法包括以下步骤:通过压力传感器检测制动压力(S110),确定与制动压力相对应的车辆的参考减速度(S120),检测车轮速度 (S130),根据车轮速度随时间的变化率计算车辆的减速度(S140),将基准车辆减速度与实际车辆减速度进行比较(S150 ),如果实际车辆减速度低于参考值(S160),则判定制动衬块为有缺陷,如果制动衬块多次被确定为有缺陷,则将制动衬块确定为缺陷(S180),并警告驾驶员 通过在灯上点亮来制动衬块的缺陷(S190)。
