The invention provides an indirect tire pressure monitoring method and system suitable for complex driving conditions, and the method comprises the steps: S1, obtaining independent wheel speed timestamp signals of each tire of a vehicle, and calculating the real-time rolling characteristics of each tire according to the wheel speed timestamp signals; s2, a real-time whole vehicle monitoring signal is obtained, the current working condition of the vehicle is recognized according to the state bit change of a specific signal value in the whole vehicle monitoring signal or the regular change of the signal, and the real-time rolling characteristics are analyzed to be forbidden or compensated according to the current working condition so as to correct the abnormal change, caused by the current working condition, of the tire rolling characteristics; and S3, calculating the tire pressure according to the corrected tire rolling characteristics based on the corresponding relationship between the tire rolling characteristics and the tire pressure. According to the invention, the accuracy of tire pressure monitoring under complex working conditions is improved, and the phenomenon of false alarm or missing alarm of an indirect tire pressure monitoring system in an actual vehicle use environment is reduced.
本发明提供一种适用于复杂驾驶工况的间接式胎压监测方法及系统,方法包括:S1,获取车辆各轮胎独立的轮速时间戳信号,根据所述轮速时间戳信号计算各轮胎的实时滚动特征;S2,获取实时的整车监测信号,根据整车监测信号中特定信号值的状态位变化或者信号的规律性变化识别车辆当前工况,根据当前工况对所述实时滚动特征进行分析禁用或补偿,以修正轮胎滚动特征因当前工况引起的异常变化;S3,基于轮胎的滚动特征与轮胎压力的对应关系,根据修正后的轮胎滚动特征计算轮胎压力。本发明提升了复杂工况下胎压监测的准确性,减少了实际用车环境中间接式胎压监测系统的误报或漏报现象。
