1. A steering control device comprising:
a rack position detection unit for detecting a rack position of an output device after an ignition of a vehicle is turned on;
a steering wheel rotation angle determination unit for determining a rotation angle of a steering wheel corresponding to the rack position;
a steering wheel display unit for displaying, on the steering wheel, a center position of the steering wheel according to the rotation angle of the steering wheel; and
a steering reaction force provision unit for providing a steering reaction force according to the rotation angle of the steering wheel,
wherein
the steering reaction force provision unit determines a current value based on a position of the steering wheel determined according to the rack position, and controls a steering motor using the current value to provide the steering reaction force,
the steering wheel display unit displays the center position of the steering wheel on the steering wheel in one of a plurality of different colors according to the rotation angle of the steering wheel, and
if the rack position is located at a one-side rack threshold and the steering wheel is rotated in a direction in which the rack position exceeds the one-side rack threshold, the steering wheel display unit displays on the steering wheel in a color different from the plurality of different colors.
