Wheel's i.e. rear wheel, steer angle adjusting system for motor vehicle i.e. four-wheeled motor vehicle, has control units with computer unit having communication interface and to send and receive data by communication interface and bus

摘要

The system has tie rods (310, 320) to connect a rear wheel carrier (300) of rear wheels (31a, 31b) to a vehicle sub frame (83). The carrier is pivotable around a rotational axis running parallel to a wheel plane, where length of the rods is adjusted by an actuator driven by a motor. An electronic stability program (ESP) control unit (10) and rear wheel steering (RWS) control units (80, 81) driven directly and/or indirectly includes a computer unit with a memory and a wired or wireless communication interface. The control unit sends and receives data by the interface and a communication bus. An independent claim is also included for a method for adjusting a steer angle of a wheel of a motor vehicle.
