1. A steering control device that controls a steering device, the steering device including a steering shaft, a turning wheel of a vehicle, the turning wheel turning due to rotation of the steering shaft, and a motor rotating the steering shaft,
the steering control device comprising a processing unit configured to execute:
a target rudder angle variable acquisition process of acquiring a value of a target rudder angle variable, the target rudder angle variable being a variable that indicates a turning angle of the turning wheel;
an attention information acquisition process of acquiring information that needs to be given attention to for traveling of the vehicle;
a target rudder angle correction process of correcting the value of the target rudder angle variable by a play compensation amount corresponding to a steering direction, the steering direction being a direction in which the value of the target rudder angle variable changes;
a restriction process of restricting the correction of the value of the target rudder angle variable by the play compensation amount, depending on the information that needs to be given attention to; and
a rudder angle control process of operating the motor by a control in which a steering angle depending on a rotation angle of the steering shaft is adopted as a control amount and the value of the target rudder angle variable is adopted as a target value of the control amount.
