Abstract
A method and apparatus for determining a center position of the vehicular steering system includes a vehicle speed sensor, a steering sensor and a control unit. The control unit uses a strategy to determine an estimate of the steering assist force. When the steering assist force is below a force threshold and a vehicle speed is above a speed threshold, the controller filters data from the steering sensor so as to rapidly determine a precise center position for the steering system.
