Abstract

A new automotive varying gear ratio system(VGRS)is introduced in this paper. Based on the analysis of foreign advanced theory in this field, a relationship among road wheel angle, steering wheel angle and vehicle speed is derived in order to achieve the optimum steering control for cornering and emergency maneuvers, whilst retaining the high-speed stability.
