A method is provided for controlling the steering feedback torque of a power steering system within a closed loop control system. The power steering system provides an actual value (TACT) of the steering feedback torque, a nominal value (TNOM) of the steering feedback torque is calculated by first means using vehicle dynamic related measurements or estimates, a difference between the actual value (TACT) of the steering feedback torque and the nominal value (TNOM) of the steering feedback torque is used as an input for a controller providing an controller output (COUT), and an input for the power steering system is provided on basis of the controller output (COUT) influencing the steering feedback torque in a way that the difference between the actual value (TACT) of the steering feedback torque and the a nominal value (TNOM) of the steering feedback torque is at least reduced and preferably eliminated.
