This paper proposes a new Electric Power Steering (EPS) control strategy that enables improvement on steering-wheel returnability. If we use a conventional EPS controller, frictional loss torque in the steering mechanism reduces steering-wheel returnability, which drivers occasionally perceive as unpleasant. To improve steering-wheel returnability for EPS-equipped vehicles, we analyze the relationship between vehicle parameter and returnability. According to this analytical result, we develop a new control strategy based on estimation of aligning torque generated by tires and road surfaces. We experiment with this proposed control algorithm using a test vehicle and confirm that it enables improved steering wheel returnability as well as better on-center feeling.
