Abstract
A controller () for a vehicular system () that includes a hand-wheel () and an electric motor () includes a torque-assist function () responsive to a signal representing the torque applied to the hand-wheel () for providing a torque-assist command to the motor (), and a steering-pull compensator () responsive to a signal representing a valid ignition cycle for modifying the torque-assist command to the motor () by an offset corresponding to a detected steering-pull condition; where the method of control includes receiving the signal indicative of the torque applied to the hand-wheel (), providing a torque-assist command to the motor () in response to the received torque signal, detecting an enabling signal related to the signal representing a valid ignition cycle, quantifying a steering-pull condition in response to the received and detected signals, and modifying the torque-assist command to the motor () by an offset corresponding to the quantified steering-pull condition.
