Abstract
The present disclosure relates to a steering control apparatus comprising: a first sensing unit that senses a steering torque using a torque sensor; a high frequency output unit that inputs a steering torque to a high pass filter and output high frequency steering torques; a detection unit that detects a first frequency corresponding to a maximum steering torque among the high frequency steering torques; a calculation unit that calculates a high frequency steering torque change rate which is the rate of change in the high frequency steering torques; a band frequency output unit that inputs the high frequency steering torque change rate to a band pass filter that passes a first frequency band including the first frequency, to output a first frequency band steering torque change rate; and a compensation unit that compensates an assist current of a steering motor on the basis of a rejection gain.
