Beschreibung
Zusammenfassung:	The invention relates to a method for controlling the steering feedback torque of a power steering system within a closed loop control system, whereby the power steering system provides an actual value (TACT) of the steering feedback torque, whereby a nominal value (TNOM) of the steering feedback torque is calculated by first processor using vehicle dynamic related measurements or estimates, whereby a difference between said actual value (TACT) of the steering feedback torque and said nominal value (TNOM) of the steering feedback torque is used as an input for a controller providing an controller output (COUT), and whereby an input for the power steering system is provided on basis of said controller output (COUT) influencing said steering feedback torque in a way that the difference between said actual value (TACT) of the steering feedback torque and said a nominal value (TNOM) of the steering feedback torque is eliminated.
