Abstract
A steering angle detecting device employs an analog sensor and a digital sensor to detect a displacement of a component which is displaceable depending on a change in a steering angle in a steering apparatus. The steering angle detecting device includes an analog sensor for detecting a displacement of the component and producing an analog signal having a potential corresponding to the position of the component, a digital sensor for detecting the displacement of the component and producing a predetermined number of pulses corresponding to a unit change in the steering angle, a basic count determining unit for determining a basic count corresponding to the steering angle based on the analog signal produced by the analog sensor when a steering angle starts to be detected, a counter for generating and holding a count corresponding to the steering angle by adding or subtracting the number of pulses produced by the digital sensor to or from the basic count, a steering angle calculating unit for calculating a steering angle based on the count, and a correcting unit for correcting the count when the component is positioned in a position corresponding to a predetermined reference steering a…
