Abstract
A steering angle of a motor vehicle is processed to obtain a correct value under any driving conditions. The vehicle speed signal from the vehicle speed sensor is compared with a preliminarily set value of the vehicle speed and it is decided whether or not an absolute value of the steering angle is higher than a preliminarily set value. The absolute angle signal is held for a predetermined time and the elapsed angle signal is converted into a digital signal. It is judged whether or not the digital signal is deviated from a reference value. A correction amount of the steering angle is calculated by incrementing with a resolving power so as to obtain a correct indication of the steering angle in any deviational conditions of the vehicle.
