Patent ID: 8200394

Claim:
A system for adjusting a wheel lock angle of a wheel of a motor vehicle wherein at least one wheel guide member, by means of which a wheel carrier of the wheel is connected to a vehicle body, wherein the wheel carrier is configured to pivot about a rotational axis which extends substantially parallel to a plane of the wheel of the vehicle, and the wheel guide member is coupled to the wheel carrier at a distance from the rotational axis, and wherein a length of the wheel guide member is configured to be adjusted by an actuator, wherein at least one actuator is driven by a motor and at least one control unit, and the control unit comprises a computer unit with a memory and at least one wire-bound or mobile communication interface, and the control unit transmits and receives data via the communication interface and at least one communication bus, wherein the system has an Electronic Stability Program (ESP) control device as a first control unit and two rear wheel steering (RWS) control devices as a second and third control device, wherein the RWS control devices are of modular design and have means for acquiring local sensor variables of the actuators, and wherein the two RWS control devices are connected directly to one another by crosscoupling by means of switches, and in the event of a fault within an RWS functionality the RWS control devices monitor one another and switch one another off, and the RWS control devices drive the actuators in such a way that stepped deactivation of the system is carried out.
