Claim 10:
11. 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
if a steering angle of the steering wheel is equal to or greater than an angle corresponding to the initial point, the controller stops transmitting a steering control signal generated by the steering angle information of the steering wheel, or
in the case that the steering angle of the steering wheel deviates by more than the angle corresponding to the initial point and then returns to the initial point again, if the steering angle information of the steering wheel coincides with the initial point information, the controller initiates transmission of the steering control signal generated by the steering angle information of the steering wheel, or
in the case that the steering angle of the steering wheel deviates by more than the angle corresponding to the initial point and then returns to the initial point again, if the steering angle of the steering wheel is equal to or less than the angle corresponding to the initial point, the controller controls a position of the rack displacement to be adjusted based on the steering angle information of the steering wheel.
