Abstract
A method and apparatus for learning the neutral position of vehicle steering angle, in which first neutral position decision means decides that the steering shaft is at a neutral position when a running speed detector detects that the vehicle speed is not less than a predetermined threshold level, that the difference in peripheral speed between the right and left drive wheels is smaller than a predetermined first straight-running threshold value and also when a steering shaft reference position sensor continues to detect a reference position of the steering shaft for at least a first count time. The vehicle steering angle is computed on the basis of the angular displacement from the neutral position thus learned.
