Abstract
A method for determining the center position of a steering wheel for a vehicle equipped with electric power steering having a brushless motor. Vehicle operating conditions corresponding to a straight direction of vehicle travel are detected. An estimated center position of the brushless motor is determined while the vehicle operating conditions are detected. A range of angular positions about the estimated center position is established in which the actual center position of the steering wheel is determined to be the position of the brushless motor equal to a midpoint of the range of angular positions.
