According to the tire pressure monitoring system, the positioning method, the tire pressure electronic control unit and the vehicle in the embodiment of the invention, the tire pressure electronic control unit responds to enter the automatic positioning mode; sending an automatic positioning instruction to each tire pressure sensor in a Bluetooth communication mode so as to enable the tire pressure sensors to enter an automatic positioning mode and send acceleration data to the tire pressure electronic control unit in the Bluetooth communication mode; receiving and acquiring the acceleration data, and acquiring tooth number coding data of a wheel speed sensor; on the basis of consistency feature matching of the acceleration data and the tooth number coding data when the tire pressure sensors reach the reference positions, the tire where each tire pressure sensor is located is positioned; and sending a positioning stopping instruction to the successfully positioned tire pressure sensor through the Bluetooth communication mode. The tire pressure electronic control unit realizes starting and stopping of automatic positioning of the tire pressure sensor and transmission of tire state data through Bluetooth two-way communication, and power consumption and transmission efficiency of the tire pressure sensor are both considered.

    本公开实施例中的胎压监测系统、定位方法、胎压电子控制单元及车辆,胎压电子控制单元响应于进入自动定位模式,通过蓝牙通信方式向各所述胎压传感器发送自动定位指令以令胎压传感器进入自动定位模式以向所述胎压电子控制单元通过蓝牙通信方式发送加速度数据;接收并获取所述加速度数据、且获取轮速传感器的齿数编码数据;基于所述加速度数据和齿数编码数据在胎压传感器到达参考位置上的一致性特征匹配,定位每个所述胎压传感器所在的轮胎;通过所述蓝牙通信方式发送停止定位指令至已定位成功的胎压传感器。胎压电子控制单元通过蓝牙双向通信,实现胎压传感器自动定位的启动及停止、以及轮胎状态数据的传输,兼顾胎压传感器的功耗和传输效率。
