The invention discloses a method for monitoring the braking failure risk of a vehicle on a long downhill road segment, and the method comprises the steps: collecting the GPS data, IMU data and oil consumption data of the vehicle in real time, so as to detect whether the vehicle drives into the long downhill road segment or not; if yes, acquiring running parameters of the vehicle in real time, and establishing a real-time running model of the vehicle on the long downhill road section; the operation parameters comprise a horn whistling state, a danger alarm lamp state, a transverse deviation distance of a right lane of the vehicle, a steering wheel included angle, a right turn lamp state, an opening and closing amplitude of a brake pedal, opening and closing times of the brake pedal and the speed of the vehicle; the real-time operation model is compared with a pre-established failure operation model to obtain the similarity between the real-time operation model and the failure operation model, and the failure operation model is established according to operation parameters of the vehicle in the long downhill road section in the braking failure state; and determining the brake failure risk of the vehicle based on the similarity between the real-time operation model and the failure operation model.
本申请公开了一种车辆在长下坡路段的制动失效风险的监测方法,该方法包括:实时采集车辆的GPS数据、IMU数据和油耗数据,以检测车辆是否驶入长下坡路段;若是,则实时采集车辆的运行参数,建立车辆在长下坡路段的实时运行模型;运行参数包括:喇叭鸣笛的状态、危险报警灯的状态、车辆右侧车道的横向偏离距离、方向盘夹角、右转灯的状态、制动踏板的开合幅度、制动踏板的开合次数、车辆的速度;将实时运行模型与预先建立的失效运行模型进行对比,以获取实时运行模型与失效运行模型之间的相似度,失效运行模型根据处于长下坡路段的车辆在制动失效状态下的运行参数建立;基于实时运行模型与失效运行模型之间的相似度,确定车辆的制动失效风险。
