Abstract: The present disclosure provides a steer-by-wire system, including a reaction force motor for providing a reaction force in a direction opposite to the direction of operation of a steering wheel; a torque sensor for detecting a rotational angle of the steering wheel according to manipulation of the steering wheel; a motor position sensor for detecting a rotation angle of the motor; a turn counter for detecting the number of rotations of the reaction force motor; and a controller for calculating a first steering angle based on the rotation angle and number of rotations of the reaction force motor.

Abstract: The present disclosure provides a steering control apparatus comprising: a first control unit for controlling a motor to supply a motor torque associated with steering on the basis of a value of a first steering torque; and a second control unit for mutually monitoring operation states with the first control unit via a communication interface and, when an abnormality occurs in the first control unit, controlling the motor, wherein, when the occurrence of an abnormality associated with the operation state of the first control unit is recognized, the second control unit determines whether or not the first control unit or the communication unit is abnormal, on the basis of a value of a second steering torque. According to the present disclosure, a redundant safety mechanism can be implemented without a separate change in a hardware design.
