Compliance Steer and Road Holding of Rigid Rear Axle for Enhancing the Running Straightness of Large Sized Vehicles

This paper concerns the control of compliance steer for the rigid axle rear suspension of large-sized buses. The distortion of rear axle alignment (Compliance Steer) by the disturbances from the road surface is one of the biggest elements which disturb the running straightness of large-sized vehicles. By redesigning the compliance steer characteristics to generate counter axle steer when disturbances are applied, the stability of running straightness will be improved.
