Abstract: A vehicle steering system for controlling a steering or steering lock angle of at least one wheel of a vehicle having a steering handle or wheel, whereby the actual manual torque or force that is to be applied by the driver for controlling the vehicle being regulated by a control device is a function of the vehicle condition or state values.

Abstract: The invention relates to a vehicle steering system for controlling a steering or steering lock angle of at least one wheel of a vehicle, comprising the following: a steering handle, especially a steering handwheel; a detecting device for detecting the degree of actuation of the steering handle; a mechanical interconnection between the steering handle and the at least one steered vehicle wheel; an adjustment unit for assisted adjustment of the steering or steering lock angle; a control device for the adjustment unit, wherein the actual manual torque or force that is to be exerted by the driver to control the vehicle is regulated by the control device depending on vehicle state parameters, wherein the control device has a vehicle state regulator which generates an adjustment parameter Treq with the aid of state parameters of the vehicle, in which the steering forces exerted by the driver would be minimal, so that practically torque-free steering could be realized and a reference variable lock-on produces a refe
