A steering force compensation apparatus of the present invention comprises: a sensor module sensing a vehicle speed, column torque, a steering angle, and a steering angular speed; a right and left deviation compensation module which respectively detects left turn column torque and right turn column torque each corresponding to a left steering angle and a right steering angle of a mutually corresponding size, whenever the vehicle speed, the column torque, the steering angle, and the steering angular speed sensed by the sensor module satisfy predetermined discrimination conditions, calculates a tolerance between the detected left turn and right turn column torque, and calculates right and left difference compensation torque based on the at least one calculated tolerance; and an assist torque compensation unit which reflects the right and left difference compensation torque to an assist torque calculated in a motor driven power steering (MDPS) module and outputs the torque to an MDPS motor.

    본 발명은 차속, 컬럼토크, 조향각 및 조향 각속도를 감지하는 센서 모듈, 센서 모듈에 의해 감지된 차속, 컬럼토크, 조향각 및 조향 각속도가 기 설정된 판별 조건을 만족할 때마다, 서로 대응되는 크기의 좌 좌향각과 우 조향각 각각에 대응되는 좌턴 컬럼토크와 우턴 컬럼토크를 각각 검출하고, 검출된 좌턴 및 우턴 컬럼토크 간의 오차를 계산하며, 계산된 적오도 하나 이상의 오차에 근거하여 좌우차 보상토크를 계산하는 좌우 편차 보상 모듈, 및 좌우차 보상토크를 MDPS 모듈에서 계산된 보조토크에 반영하여 MDPS 모터로 출력하는 보조토크 보상부를 포함하는 것을 특징으로 한다.
