Abstract
A method for controlling a steering apparatus () of a vehicle produces an error signal () by subtracting a hand wheel torque () and a column torque () from a desired operator torque () to be applied to a hand wheel () of the vehicle. A controller () receives at least one vehicle condition signal () and determines the desired operator torque (). The desired operator torque () is filtered into a low frequency torque component () and a high frequency torque component (). The steering apparatus () is controlled based on the low frequency torque component () and the high frequency torque component ().
