Method for controlling the steering feedback torque

The invention relates to a method for controlling the steering feedback torque of a power steering system (10) within a closed loop control system, whereby the power steering system (10) provides an actual value (T ACT ) of the steering feedback torque, whereby a nominal value (T NOM ) of the steeri...

Beschreibung
Zusammenfassung:	The invention relates to a method for controlling the steering feedback torque of a power steering system (10) within a closed loop control system, whereby the power steering system (10) provides an actual value (T ACT ) of the steering feedback torque, whereby a nominal value (T NOM ) of the steering feedback torque is calculated by first means (12) using vehicle dynamic related measurements or estimates, whereby a difference between said actual value (T ACT ) of the steering feedback torque and said nominal value (T NOM ) of the steering feedback torque is used as an input for a controller (11) providing an controller output (C OUT ), and whereby an input for the power steering system (10) is provided on basis of said controller output (C OUT ) influencing said steering feedback torque in a way that the difference between said actual value (T ACT ) of the steering feedback torque and said a nominal value (T NOM ) of the steering feedback torque is eliminated.
