Abstract
A steering system for a vehicle comprises a front wheel turning mechanism for turning the front wheels in response to operation of a steering wheel, a steering ratio changing mechanism inserted into the front wheel turning mechanism to change the ratio of the turning angle of the steering wheel to the turning angle of the front wheels, and a vehicle speed sensor for detecting the vehicle speed. The steering ratio changing mechanism is controlled to increase the ratio as the vehicle speed increases, and as the vehicle speed increases, the control speed of the steering ratio changing mechanism is lowered.
