A trial method to test optimal acceleration slip ratio based on wheel torque sensor dur- ing vehicle acceleration mode is proposed. and the testing principle and process have been introduced in de tai l. 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 acceler- ation slip regulation on a slippery road surface.
