| 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。仿真证明了该算法的可行性。将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。

| Abstract: | A longitudinal force model of tire with two parameters was developed for estimating the longitudinal stiffness and roiling radius of the tire. The method of estimating two parameters was established by using a mixed technique of pattern search and least-square regression. The simulation program was made on Matlab platform with algorithm, and the validity of this algorithm was demonstrated by the perfect coincidence of the simulation and true results. Finally, the algorithm was applied to the vehicle real test data. It showed that measured tire pressure and estimated longitudinal stiffness are approximately inversely proportional. It also suggested that longitudinal stiffness estimate might be used to predict tire inflation pressure. |
