Abstract

In this paper, a new technology of power steering for in-wheel-motor driven electric vehicles has been developed. Through controlling the driving torque of the two in-wheel traction motors, a proper power steering assist torque can be generated, which can be used to compensate the assist steering torque generated by hydraulic pump or direct power steering motor, or even completely make them unnecessary. Therefore, the power steering system can be designed with more compactness, and operated with high efficiency and less maintenance requirement.
