Abstract
A steering angle calculating circuit includes a first neutral point calculating circuit, a second neutral point calculating circuit, and an absolute angle calculating circuit. The first neutral point calculating circuit calculates a motor neutral point (θm01), based on a steering angle detected by a steering sensor and a rotation angle of a motor detected by the relative angle sensor, when a drive source for driving a vehicle is started. The second neutral point calculating circuit calculates a motor neutral point when the steering angle detected by the steering sensor falls within a predetermined angle range in which a specific stroke with respect to the steering angle is constant. After the motor neutral point is calculated by the second neutral point calculating circuit, the absolute angle calculating circuit calculates the steering angle as an absolute angle, using the motor neutral point calculated by the second neutral point calculating circuit.
