Abstract
A steering angle detecting apparatus for accurately and surely detecting a steering angle of a motor vehicle. The apparatus is equipped with a turning angle detector for detecting a turning angle of a steering wheel of the motor vehicle. In addition, the apparatus estimates a turning angle of the steering wheel on the basis of the difference in speed between left and right wheels of the motor vehicle so as to calculate the difference in phase between the detection turning angle and the estimation turning angle. For detecting the accurate vehicle steering angle, the detection turning angle is corrected on the basis of the calculated phase difference therebetween.
