The invention discloses a tire pressure sensor self-positioning method, a tire pressure sensor self-positioning device and a vehicle. The tire pressure sensor self-positioning method comprises the steps that acceleration data of m periods and wheel tooth information of the m periods of a tire are obtained, and m is larger than or equal to 2; a first phase difference is calculated according to the acceleration data, the first phase difference is the phase difference between the phase corresponding to the acceleration data of the kth period and the phase corresponding to the acceleration data of the hth period, k is larger than 0 and smaller than or equal to m, h is larger than 0 and smaller than or equal to m, and h is not equal to k; calculating a gear tooth phase difference according to the gear tooth information, wherein the gear tooth phase difference is the phase difference between the gear tooth phase of the kth period and the gear tooth phase of the hth period; and determining the corresponding relationship between the tire pressure sensor and the tire according to the first phase difference and the gear tooth phase difference. According to the invention, errors existing in the self-positioning process of the tire pressure sensor can be effectively reduced, so that the accuracy of the self-positioning process of the tire pressure sensor is improved.
本发明公开了一种胎压传感器自定位方法、自定位装置和车辆。该胎压传感器自定位方法包括:获取轮胎的m个周期的加速度数据和m个周期的轮齿信息,其中,m≥2;根据加速度数据计算第一相位差,第一相位差为第k个周期的加速度数据对应的相位与第h个周期的加速度数据对应的相位之间的相位差,其中,0<k≤m,0<h≤m,h≠k;根据轮齿信息计算轮齿相位差,轮齿相位差为第k个周期的轮齿相位与第h个周期的轮齿相位之间的相位差;根据第一相位差和轮齿相位差确定胎压传感器与轮胎的对应关系。本发明能够有效降低胎压传感器自定位过程中存在的误差,进而提高胎压传感器自定位过程的准确性。
