| 摘 要： | 路面附着系数是影响车辆行驶安全性的重要因素,利用轮边驱动电动汽车驱动力矩可以对路面利用附着系数进行观测。当观测到μ-λ曲线接近于峰值点时,将该时刻的轮胎利用附着系数作为路面峰值附着系数,并根据识别的路面峰值附着系数进行驱动防滑控制。该方法能够有效防止轮胎滑转,提高车辆行驶稳定性。

| Abstract: | In an in-wheel-motor drive vehicle the tire-road friction coefficient is observed by means of drive torque,which can be acquired accurately and controlled easily.When the adhesion coefficient is close to the maximum tire-road friction coefficient,the current adhesion coefficient is used as maximum tire-road friction coefficient to control the drive torque.This method can avoid tire slip effectively,and hence improve the driving stability of the vehicle. |
