Steering control system, steering control device, and steering control method

A steering control device, comprising:

• a rack stroke calculation unit calculating a rack stroke including a moving direction and a moving amount based on a position of a rack detected by a position sensor;
• an area entry determination unit determining whether an end of a rack bar enters a preset anti-jam control area based on the rack stroke and outputting a flag corresponding to a result of the entry;
• and
• a driving controller, if the end of the rack bar enters the anti-jam control area, reducing at least one of a target driving speed and a target output current of an actuator to a preset control value and controlling a driving of the actuator while the rack moves by a target rack stroke calculated based on at least one of a steering angle of a steering wheel and a rotation speed of the steering wheel.
