The present invention relates to a friction compensation apparatus of an MDPS system and a friction compensation method thereof. According to the friction compensation apparatus of an MDPS system receiving a column torque signal, processing the column torque signal, and outputting friction compensation torque, the friction compensation apparatus comprises: a accumulation speed control unit controlling the speed of accumulating information of a compensation section set in the column torque signal; and a compensation amount control unit for each vehicle speed controlling the accumulation speed control unit to control the accumulation speed to be faster or slower in accordance with the vehicle speed and controlling a compensation gain to be smaller or larger in accordance with the vehicle speed to output the friction compensation torque.
본 발명은 엠디피에스 시스템의 마찰 보상 장치 및 방법에 관한 것으로, 컬럼토크 신호를 입력받아 처리하여 마찰 보상 토크를 출력하는 엠디피에스 시스템의 마찰 보상 장치에 있어서, 상기 컬럼토크 신호에 설정된 보상구간의 정보를 누적하는 속도를 조절하는 누적속도 조절부, 및 상기 누적속도 조절부로 하여금 차속에 따라 보상구간 정보의 누적 속도를 빠르거나 느리게 조절하도록 제어하고, 또한 상기 차속에 따라 보상량 게인을 작거나 크게 조절하여 마찰 보상 토크를 출력하는 차속별 보상량 조절부를 포함한다.
