摘  要:
通过建立轮胎动力模型,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两个参数进行了动态估计。该方法避免了求解模型参数时最优化函数导数的求取,改善了由于初值选取不当,迭代不收敛的困难,MATLAB仿真说明了该算法的可行性。该方法应用于车辆的实际数据,可以实时估计轮胎参数变化,对于间接胎压监测系统的研究具有重要的意义。

摘  要:
An dynamical model was developed in this paper for dynamic estimation of the longitudinal stiffness and rolling radius of the tires. The method estimating the tire parameters is established by using a mixed technique of pattern search and least-square regression, which can avoid regression divergence when initial parameters are not optimally selected. 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 .The algorithm applied to real vehicle data may estimate the tire parameters in time and it is important to the research of tire pressure monitoring system.
