Abstract
An all-wheel steering system for a motor vehicle is described which has an active front axle steering system and an active rear axle steering system. The front axle steering system includes a gear ratio unit which is coupled to a steering wheel. The gear ratio unit is configured to define a front axle steering angle as a function of a steering wheel angle and a front axle steering ratio. In addition, the gear ratio unit is coupled to the rear axle steering system in such a way that the front axle steering ratio is adjustable as a function of a rear axle steering angle. Further, a motor vehicle having such an all-wheel steering system is discussed. Also presented is a method of operating an all-wheel steering system for a motor vehicle.
