| 摘 要： | 提出了一种含有两个参数的轮胎纵向力模型,并通过该模型利用基于模式搜索的最小二乘法对轮胎的纵向刚度和滚动半径进行了动态估计.该算法应用于车辆的实际试验数据,结果证明轮胎的压力与轮胎纵向刚度近似成反比,这为利用轮胎纵向刚度监测轮胎压力变化,提供了可靠的理论依据.

| Abstract: | An longitudinal force model of tire with two parameters was developed in this paper for estimating the longitudinal stiffness and rolling radius of the tire.The method estimating the tow parameters is established by using a mixed technique of patten search and least-squre regresson.The algorithm applied to real teast vehicle data shows that measured tire pressure and estimated longitudinal stiffness are approximately inversely proportional.It also suggests that longitudinal stiffness estimate may be used to predict tire inflation pressure. |
