1. A steering control device configured to control a steering device, the steering device including a steering wheel, a steering shaft coupled to the steering wheel, a turning wheel of a vehicle, the turning wheel being configured to turn along with rotation of the steering shaft, and a motor configured to rotate the steering shaft, the steering control device comprising:
a processor configured to execute:
an alarm information acquisition process of acquiring information indicating that an alarm needs to be issued to a driver of the vehicle, the information indicating that an alarm needs to be issued to the driver indicating that the vehicle is in a situation where steering for avoiding danger needs to be performed;
a vibration process of vibrating the steering wheel in a predetermined region by operating the motor, in a situation where the alarm needs to be issued, the predetermined region being where a turning angle of the turning wheel does not change even when the steering wheel rotates;
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 the turning angle of the turning wheel and that is set to a value for avoiding the danger in the situation where the steering for avoiding the danger needs to be performed;
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 of the steering device; 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, wherein
the processor is further configured to start the vibration process after the value of the target rudder angle variable is corrected by the play compensation amount corresponding to the steering direction for avoiding the danger.
