1. A method of controlling a power steering system of a vehicle, the method comprising:
- determining, by a processor, a yaw rate of the vehicle based on a wheel velocity, measured by a road wheel velocity sensor;
generating a hand wheel angle signal, using a speed correction factor that is a function of a velocity of the vehicle, the hand wheel angle signal indicates a position of a hand wheel of the vehicle based on the yaw rate; and
controlling the power steering system by using the hand wheel angle signal.

Abstract
A method of controlling a power steering system of a vehicle is provided. The method determines a yaw rate of the vehicle. The method generates a hand wheel angle signal that indicates a position of a hand wheel of the vehicle based on the yaw rate. The method controls the power steering system by using the hand wheel angle signal.
