The invention relates to a Bluetooth-based tire pressure sensor positioning method. The tire pressure sensor positioning method comprises the steps that S1, Bluetooth connection is established between a vehicle ECU and a tire pressure sensor, and clock synchronization is established on the vehicle ECU and the tire pressure sensor; s2, the tire pressure sensor periodically sends a positioning data packet to the vehicle ECU, the positioning data packet at least comprises backspacing time, and the backspacing time is used for representing the moment when the tire pressure sensor reaches the reference point; s3, the vehicle ECU calculates the corresponding moment when the vehicle ECU side reaches the reference point based on the backspacing time; s4, the vehicle ECU carries out deviation degree statistics on the obtained ABS information based on the corresponding moment, and a tire pressure sensor is positioned according to a statistical result; and S5, if the vehicle ECU positions the tire pressure sensor, the vehicle ECU instructs the tire pressure sensor to stop sending the positioning data packet. The tire pressure sensor can be effectively positioned, and the service life of the tire pressure sensor can be prolonged.
本发明涉及一种基于蓝牙的胎压传感器定位方法。该胎压传感器定位方法包括步骤:S1,车辆ECU和胎压传感器建立蓝牙连接,在车辆ECU和胎压传感器上创建时钟同步;S2,胎压传感器周期性地发送定位数据包到车辆ECU,定位数据包至少包括回退时间,回退时间用于表征胎压传感器达到参考点的时刻;S3,车辆ECU基于回退时间计算车辆ECU侧达到参考点的对应时刻;S4,车辆ECU基于对应时刻对所获取的ABS信息进行偏离程度统计,根据统计结果定位胎压传感器;S5,若车辆ECU定位胎压传感器,则车辆ECU指令胎压传感器停止发送定位数据包。本发明能实现胎压传感器的有效定位,并能延长胎压传感器的使用寿命。
