Abstract:
A turning angle detecting device includes: a first storage unit configured to store a turning angle neutral point correction value being a difference between a median of the turning angles at respective limits in right and left steering and the turning angle in a straight traveling state; a second storage unit configured to store an initial position of a movable portion of an actuator of a wheel turning mechanism in the straight traveling state; a first turning angle calculating unit configured to calculate a first turning angle with respect to the median of the turning angles at the respective limits based on a detection value of a position of the movable portion; and a second turning angle calculating unit configured to calculate a second turning angle based on the detection value, the turning angle neutral point correction value, the initial position and the first turning angle.
