Claim 5:
6. A steering control method of a vehicle, the steering control method comprising:
detecting 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;
determining 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
setting, 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, a point where the alignment starts to be misaligned as an initial point, storing steering angle information of the steering wheel at the initial point as initial point information, and controlling the steering wheel and the rack displacement to be aligned by using the initial point information,
wherein the determining comprises, 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, determining that the steering wheel and the rack displacement are misaligned.
