Abstract
A steering control device includes: a target rotation angle calculation circuit that calculates a target rotation angle of a shaft; an offset angle calculation circuit that calculates an offset angle relative to the target rotation angle; a final target rotation angle calculation circuit that calculates a final target rotation angle of the shaft; and a feedback control circuit that executes feedback control that adapts a real angle to the final target rotation angle. The offset angle calculation circuit calculates an estimated rotation angle deviation based on a value of a current of a turning motor immediately before a specific event occurs, and calculates the offset angle by subtracting the real angle and the estimated rotation angle deviation from the target rotation angle.
