1. A motor vehicle, comprising:
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 a position of the rear wheels in relation to a position of the front wheels for controlling the actuator, wherein the at least two characteristic curve fields differs from each other below a predetermined steering wheel rotation angle and the at least two characteristic curve fields do not differ from each other above the predetermined steering wheel rotation angle, wherein the control device is configured to select one of the at least two characteristic curve fields depending on at least one parameter relating to a position of the steering wheel or a change in position of the steering wheel, to select and use a first of the at least two characteristic curve fields, when for a predetermined duration the steering wheel rotation angle resides in a predetermined steering wheel rotation angle range for a predetermined duration and when a steering wheel rotation angle velocity does not exceed a steering wheel rotation angle limit velocity during the predetermined duration, and to select and use a second of the at least two characteristic curve fields, when the steering wheel rotation angle is greater than the predetermined steering wheel rotation angle, wherein, when driving the motor vehicle in reverse, the actuator reversibly and continuously adjusts the rear wheels commensurate with the selected characteristic curve field between a steering position that is identical to a steering position of the front wheels or a steering position that is opposite to the steering position of the front wheels. |
