Abstract
A method is provided which permits accurate estimation of the neutral point of a steering wheel while a vehicle is traveling. In this method, a wheel angle is detected whenever a condition, wherein the car speed has reached a specified speed or higher, the working pressure of a hydraulic power steering has not virtually risen yet, and the steering wheel has not yet virtually steered, lasts for a specified time; the detection frequency distribution, which corresponds to the detected wheel angles, is determined; the weighted mean value of the wheel angles is calculated from the detection frequency distribution; and the weighted mean value is estimated as the neutral point of the steering wheel.
