Patent number: 8983728Abstract: A motor vehicle includes a steering wheel for steering front wheels of the motor vehicle, an actuator for automatically steering rear wheels of the motor vehicle, and a control device storing at least two different characteristic curve fields relating to the position of the rear wheels in relation to the position of the front wheels for controlling the actuator. The control device selects one of the two characteristic curve fields depending on a parameter relating to the position of the steering wheel or a change in the position of the steering wheel. When driving the motor vehicle in reverse, the actuator reversibly and continuously adjusts the rear wheels between a steering position that is identical to a steering position of the front wheels and a steering position that is opposite to the steering position of the front wheels.Type: GrantFiled: August 17, 2012Date of Patent: March 17, 2015Assignee: Audi AGInventors: Christoph Kossira, Hugo Müller, Ulrich Voll
