Abstract

Abstract: To study the resistance torque of the steering wheel of a commercial vehicle, the LuGre model is introduced into the steering dynamics analysis of a commercial vehicle, and the model for aligning torque and steering friction resistance torque of tire and the resistance torque model of steering wheel are established. With these models the relationship among steering resistance torque, steering angle and vehicle speed of a CA1045 light truck is analyzed. The comparison between the results of simulation and real vehicle test shows that their difference in steering resistance torque is less than 5 N·m.

Key words: commercial vehicle, aligning torque, friction resistance torque, steering wheel resistance torque
