Abstract
A vehicle steering system includes a rack and pinion mechanism having a pinion functionally coupled to a steering wheel and a rack meshing with the pinion and functionally coupled to steerable wheels and a mechanism for displacing the rack in the axial direction thereof to steer the steerable wheels independently of steering operation initiated by the steering wheel. The rack and pinion mechanism comprises a variable gear ratio rack and pinion mechanism having a variable gear ratio, which is the lowest when the steering wheel is in a neutral position and becomes higher as the steering angle of the steering wheel becomes large.
