Abstract
A steering system for a vehicle with front and rear wheels suspended from a vehicle body through a suspending mechanism, comprising a front wheel steering mechanism for steering the front wheels at an angle in accordance with a steering operation of a driver, and a rear wheel steering mechanism for steering the rear wheels at an angle in accordance with a travelling state of the vehicle. The rear wheel steering mechanism has an arrangement for determining a steered angle correction quantity of the rear wheels in correspondence with a cushioning state of the wheel suspending mechanism, and an arrangement for specifying the steering angle of the rear wheels in accordance with the steered angle correction quantity.
The cushioning state may be ascertained by detecting a cushioning stroke of the suspending mechanism or a roll angle of the vehicle.
