Claim 0:
1. A steering control device of a vehicle, the steering control device comprising:
an overheat detector configured to detect whether of an overheating state of a reaction force motor based on motor temperature information of the reaction force motor, which is included in a steering column module connected to a steering wheel of the vehicle and mechanically separated from a steering rack module connected to a rack of the vehicle;
an alignment determiner configured to determine whether of an alignment of the steering wheel and a rack displacement based on steering angle information of the steering wheel and position information of the rack displacement; and
a controller configured to, in response to the overheating state of the reaction force motor being detected and determined that the alignment of the steering wheel and the rack displacement is misaligned, set a point where the alignment starts to be misaligned as an initial point, store steering angle information of the steering wheel at the initial point as initial point information, and control the steering wheel and the rack displacement to be aligned by using the initial point information,
wherein in the case that a position of the rack displacement enters within a preset range at an end of a rack, if at least one of a decrease of a current amount of the reaction force motor and a decrease of a feedback torque of the reaction force motor is detected, the alignment determiner determines that the steering wheel and the rack displacement are misaligned.
