The invention provides a tire pressure monitoring method and system. The method comprises the following steps: obtaining a first vehicle speed of each wheel in a preset duration according to a wheel rotating speed corresponding to each wheel; obtaining a second vehicle speed of the vehicle within a preset duration according to the satellite positioning signal; and comparing each first vehicle speed with the second vehicle speed to obtain a tire pressure monitoring result of each wheel. According to the invention, the wheel rotating speed corresponding to each wheel and the satellite positioning signal of the vehicle are obtained by using the existing wheel rotating speed sensor and the positioning sensor, the first vehicle speed is converted through the wheel rotating speed, and the second vehicle speed is converted through the satellite positioning signal; and finally, the tire pressure monitoring result of each wheel is obtained based on the comparison of the first vehicle speed and the second vehicle speed, the cost is not increased, and the tire pressure of each wheel can be monitored.
本发明提供一种胎压监测方法及系统。该方法包括:根据各个车轮对应的车轮转速得到各个车轮在预设时长内的第一车速;根据卫星定位信号得到车辆在预设时长内的第二车速;将各个第一车速分别与第二车速进行对比,得到各个车轮的胎压监测结果。通过本发明,利用现有的车轮转速传感器和定位传感器获取各个车轮对应的车轮转速以及车辆卫星定位信号,通过车轮转速换算出第一车速以及通过卫星定位信号换算出第二车速,最后基于第一车速和第二车速的对比得到各个车轮的胎压监测结果,不增加成本,且能实现对各个车轮的胎压进行监测。
