Abstract
Two strategies of using traction effort differential to steer automotive vehicles was applied to a swing-arm vehicle model with independent wheel traction. One of them is that the traction effort differential was applied to the front wheel pair to generate the rotation speed differential and the longitudinal tyre force differential between the front wheels. The other is that the traction effort differential between the front wheels was not only used to generate the rotation speed differential and the longitudinal tyre force differential between the front wheels, but also applied to control the steering angles of the front tyres. The vehicle steering performances associated with movebility, tyre slip forces and tyre wear are investigated and presented in this paper.
