Abstract
A method for detecting an absolute steering angle of a steering angle sensor such as encoder for a vehicle wherein the steering angle sensor generates an output signal indicating a relative rotation angle of a steering shaft of the vehicle and at least one reference signal representing a reference position for every one rotation of the steering shaft. The method comprises the steps of setting a deviation .DELTA..theta. between the reference position and an actual straight-ahead driving state position responsive to the output signal and the reference signal, storing the deviation .DELTA..theta. in a memory of a computer which holds the deviation .DELTA..theta. while the computer is disconnected from a battery, determining a steering angle with the reference position responsive to the output signal and the reference signal, and correcting by the deviation .DELTA..theta. the steering angle to obtain the absolute steering angle.
