Abstract
A steering control device includes control circuitry configured to perform synchronization control. The synchronization control includes a target synchronization angle calculating process of calculating a target synchronization angle that is a steering-side rotation angle satisfying a predetermined correspondence relationship with respect to a turning-side rotation angle; a target relay angle calculating process of calculating a target relay angle that is located closer to a first side in a circumferential direction than a first-side angle is, the first-side angle being one of the steering-side rotation angle and the target synchronization angle and being located closer to the first side than another of the steering-side rotation angle and the target synchronization angle is; and a motor driving process of operating a steering-side motor such that the steering-side rotation angle reaches the target synchronization angle after operating the steering-side motor such that the steering-side rotation angle reaches the target relay angle.
