摘　　要：轮胎气压的盈亏影响了汽车的安全性、经济性和操纵稳定性。胎压监测系统(TPMS)越来越成为汽车的标准配备。胎压监测系统主要有直接式、间接式和混合式三种。间接式胎压监测系统由于其没有额外的硬件支出、不影响轮胎动平衡特性而具有一定优势。本文分析轮胎扭转高阶频点,得出轮胎扭转高阶频点与胎压变化的相关特征,建立了间接式胎压监测算法,实现了根据单一车辆轮速信号进行轮胎欠压预报,为胎压监测系统的建立提出一种新方法。The profit and loss of tire pressure affects the safety,economy and handling stability of the vehicle.Tire pressure monitoring system(TPMS) is increasingly becoming the standard equipment for cars.There are three ways to monitor tire pressure:direct,indirect and hybrid.The indirect tire pressure monitoring system has some advantages because it has no additional hardware and does not affect the tire dynamic balance characteristics.Based on the torsional high-order frequency points,the correlation between torsional high-order frequency pointsand tire pressure is obtained,and an indirect tire pressure monitoring algorithm is established.The prediction of single tire under pressure based on wheel speed signal is realized,which provides a new method for the establishment of tire pressure monitoring system.
