ABSTRACT:
In a vehicle with a hand wheel, steerable wheels positionally responsive to the hand wheel and a steering position sensor coupled to the handwheel and providing a handwheel angle signal indicative of an angular position of the handwheel, a steering angle determination method comprising the steps of: first filtering the handwheel angle signal to provide a first filter output; defining a comparison window around the first filter output; comparing the handwheel angle signal to the comparison window; when the handwheel angle signal is within the comparison window, second filtering the handwheel angle signal to provide a second filter output; when the handwheel angle signal is not within the comparison window, maintaining the second filter output fixed; and determining a steer angle signal as the difference between the handwheel angle signal and the second filter output, wherein offsets between the handwheel angle signal and steered positions of the steerable wheels are compensated for.
