Patent ID: 7036626

Claim:
A vehicle steering system for controlling a steering or steering lock angle of at least one wheel of a vehicle having a steering means, comprising: a detection device for recording a degree of actuation of the steering means; a mechanical actuation link between the steering means and at least one steered vehicle wheel; an actuator to provide supported adjustment of a steering or steering lock angle; and a control device for said actuator, wherein an actual manual torque or force that is to be applied by a driver to control said vehicle is regulated by said control device as a function of vehicle condition values, wherein said control device has a condition regulator, which generates an adjustment parameter T req for said control device by means of condition values of the vehicle, wherein steering forces to be applied by said driver would be minimal, so that a most torque-free possible steering would be achievable, and wherein a reference value lock-on for a manual torque T driver,req to be applied by the driver produces a guide value T ref .
