英文摘要：

Optimal acceleration slip ratio of driving wheel is key parameter of acceleration slip regulation.In this paper,A trial method to test optimal acceleration slip ratio based on wheel torque sensor during vehicle acceleration mode is proposed,and the testing principle and process have been introduced in detail.Based on the vehicle test platform,the relationship between adhesion coefficinet and slip ratio of ice road and snow road have been tested with different tire load and throttle opening,and the optimal slip ratio range of driving wheel has been achieved,which provides the aim of acceleration slip ratio to study acceleration slip regulation on a slippery road surface.
