Abstract
The present invention relates to an aid steering control apparatus comprising: a sensing unit configured to sense at least one of a steering angle and a pinion angle, and a rack force; a change amount calculating unit configured to calculate at least one of a steering angle change amount, which is a change of the steering angle, and a pinion angle change amount, which is a change of the pinion angle, and a rack force change amount, which is a change of the rack force; a first carrier calculating unit configured to calculate a first carrier that is a rack force change amount for the steering angle change amount or a rack force change amount for the pinion angle change amount; and a compensating unit configured to calculate a rack force maximum value and a rack force minimum value, which are rack forces of points where a sign of the first carrier is changed by determining the sign of the first carrier, and to compensate for a steering torque based on a difference between the rack force maximum value and the rack force minimum value, and the points.
