摘　　要：通过对单轮车辆模型滑转的过程参数分析,定性研究了角加速度与滑转率的相互关系。并结合实车滑转试验,研究了车辆驱动轮附着系数、滑转率以及角加速度在试验过程时间中的变化情况。结果表明,在驱动轮滑转过程中滑转率随着角加速度的增大而不断增大,这为采用驱动轮角加速度进行路面识别提供了可靠的理论依据。By analyzing the process parameter of slipping of a single-wheel vehicle model, qualitative study of the relationship between angular acceleration and slip radio is carried out. And combined with a real vehicle slip test, the change of adhesion coefficient of the driving wheel, slip ratio and angular acceleration during test is studied. The results show that, slip ratio increases with the angular acceleration during slipping of the driving wheel, this provides reliable theoretical basis for road identification with angular acceleration of the driving wheel.
