摘要
在已知车速基础上,对四个轮心的纵向速度分别推导,考虑了转向桥与非转向桥的区别。为提高滑移率精度,对稳态和瞬态转向进行修正,充分考虑转向运动传递的不均衡性,得到了一定精度的滑移率数值,为滑移率估算提供了一种实用性很强的方法。
This paper aims for improving wheel slip which is an important estimate of automotive control systems. After vehicle velocity estimation, the four wheel center＇s velocities are estimated, considering the difference between steering axle and non steering axle. In order to get a better result,the estimation is modified in steady steering state and transient steering state. While estimating, the unbalance of steering transfer is mature. At last,a precise wheel slip is gained. Abovementioned method is very practical for wheel slip estimation.
