Tire pressure sensor positioning method, system and device

The invention provides a tire pressure sensor positioning method, system and device, and the method comprises the following steps: monitoring each response signal correspondingly returned by a target tire pressure sensor in response to a distance measurement signal based on the distance measurement signal emitted at different spatial positions; calculating first distance data between the different spatial positions and the target tire pressure sensor according to first time difference data between the sending of the distance measurement signal and the receiving of the corresponding response signal; based on the multiple pieces of first distance data, the installation position information of a target tire pressure sensor on the motor vehicle is determined, the installation position information is matched with the position information of all tires of the motor vehicle, and the tire where the target tire pressure sensor is located is determined. According to the method, the mounting position information of the t
