A method for operating an electromechanical steering system for a motor vehicle with variable chassis height, with a steering rack, which is driven by a servo motor through a recirculating ball screw drive, with a control unit, which receives input signals and generates output signals for driving the servo motor, the output signals being representative of an assist torque to be provided by the steering system, may be characterized in that, in operation, the control unit may receive or generate a chassis height signal that may indicate a current chassis height of the vehicle, and may limit the assist torque, on the basis of the chassis height signal, to an upper limit, wherein the upper limit may be decreased with an increase of the difference between the current chassis height and a mean chassis height.

Steering system with overload protection

A method of calculating the offset of a yaw rate signal may be based at least in part on signals representing pinion angle, wheel speed, and yaw rate. These signals may be determined, and threshold comparisons may be performed, and determination of the yaw rate signal may be based at least in part on the results of the threshold comparisons.

Yaw rate signal offset calculation

An electric power steering system may be controlled by superimposing a driver demand and a driver assistance device demand value to calculate a driver requested support value, in which a virtual driver support value may be calculated based on driver demand and a correction driver support value may be calculated based on a driver assistance device demand value, and the driver requested support value may be calculated as a combination of the virtual correction driver support value and the virtual driver support value.

Control in an electric steering system

The invention refers to a steering device and a method for controlling a steering device with steering power support means for a motor vehicle with at least one steerable road wheel.
