Abstract
A steering system for a motor vehicle, comprising at least one steered axle, an actuator, an actuator motor and a steering mechanism. The actuator and the steering mechanism, respectively, each have a mechanical gear ratio. The steered axle, the actuator motor, the actuator and the steering mechanism are operatively connected with one another. Steering movements initiated by the driver and movements initiated by the actuator motor are superimposed by the actuator. The superimposed movement is passed to the steering gear, which relays this movement as steering angle to the wheels of the steered axle. The steering gear mechanical gear ratio is configured to be variable which enables selectively adjustable relationships between the steering wheel movements and the steering angles of the steered wheels and avoids the loss of good steering feel for the driver.
