Abstract
A motor vehicle is provided with a steering control system in which rear wheels are steered in response to steered angle of front wheels and vehicle speeds. The control system includes a first speed sensor for detecting a vehicle speed in association with a rotation of the front wheels and a second speed sensor for detecting a vehicle speed in association with a rotation of the rear wheels. The steering of the rear wheels is controlled by a steering control unit in dependency on a ratio of a vehicle speed signal from the first speed sensor with respect to a vehicle speed signal from the second speed sensor. Thus, the steering control unit transmits a signal for restricting steering of the rear wheels in a case where a condition in which the ratio of the vehicle speed signals from the first and second sensor is out of a predetermined range continues for a predetermined time.
