The invention discloses a failure strategy control method based on failure of a direct tire pressure monitoring sensor. The failure strategy control method comprises the following steps: step S101, acquiring a CAN signal and an LIN signal of a vehicle through an OBD interface of the vehicle; step S102, reading a wheel speed pulse signal and a tire pressure signal from the CAN signal and the LIN signal of the vehicle; and S103, judging whether the direct tire pressure monitoring sensor fails or not according to the wheel speed pulse signal and the tire pressure signal, and if the direct tire pressure monitoring sensor fails, performing tire pressure monitoring by adopting a failure strategy. According to the failure strategy control method based on the failure of the direct tire pressure monitoring sensor, the most matched strategy can be flexibly selected for tire pressure monitoring according to the failure condition of the direct tire pressure monitoring sensor.
本发明公开了一种基于直接式胎压监测传感器失效时的失效策略控制方法,它包括:步骤S101、通过车辆OBD接口获得车辆的CAN信号和LIN信号;步骤S102、从车辆的CAN信号和LIN信号中读取轮速脉冲信号和胎压信号;步骤S103、根据轮速脉冲信号和胎压信号判断直接式胎压监测传感器是否失效,若直接式胎压监测传感器失效,则采用失效策略进行胎压监测。本发明提供一种基于直接式胎压监测传感器失效时的失效策略控制方法,可以根据直接式胎压监测传感器的失效情况,灵活选择最匹配的策略进行胎压监测。
