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.

A device for adjusting the camber and/or the toe of a vehicle wheel of a motor vehicle includes a wheel carrier, which has a wheel-side carrier part and an axle-side guide part, between which rotary parts that can be rotated relative to each other are arranged, wherein at least one of the rotary parts can be adjusted in both rotational directions by means of a drive and a gear stage in order to adjust the toe and/or the camber. The gear stage for the rotary part is configured as harmonic drive gear train having a driving, elliptical drive disk, and a stationary, internally toothed ring gear.

A method for operating a mechatronic chassis device of a motor vehicle, wherein the mechatronic chassis device has an arrangement with two servomotors which, when activated, individually change both a toe angle (&#x3b4;) of a wheel and a camber angle (&#x3b5;) of the wheel. The servomotors are controlled on the basis of target values in a predetermined manner, wherein if a first servomotor cannot be placed into operation, an emergency program is started and the second servomotor is controlled in a manner different from the predetermined manner such that a lateral force on the wheel is adjusted to a predetermined desired value.
