Abstract: Since the four-in-wheel-motors drive (FWMD) electric vehicle (EV) has a four-wheel independent steering, this paper presents a novel control method for an electric power steering system with a dead-zone execution mechanism. A mathematical model was derived for execution mechanisms from the empirical data. A 'dead-zone inverse transforming compensation' was designed to eliminate ill effects caused by dead-zone. The experiment in a real car environment proves the proposed method.

Keywords: four-in-wheel-motor drive; electric vehicles; electric power steering; steering control; dead-zone inverse transforming compensation; power steering control; vehicle control.
