The present invention relates to an MDPS pulling compensation system and a method thereof, which can detect the position of a rack bar to compensate for the position of the rack bar such that the vehicle may be driven in a straight manner when a vehicle is pulled even when the vehicle is steered in a straight manner. To this end, the MDPS pulling compensation system of the present invention includes a control unit (20) which can detect the position of a steering wheel (11) in the motor driven power steering (MDPS) of a vehicle (1) and the position of a rack bar (16) to control the direction of the steering wheel (W) of the vehicle (1), compare the position of the steering wheel (11) to the position of the rack bar (16), and can control the rack bar (16) to be moved to a neutral position when it is determined that the position of a rack bar (16) is not neutral in a state in which the steering wheel (11) is neutral, wherein the steering wheel is steered in a strightly driven manner in the neutral state.

    본 발명은 차량이 직진 조향에도 불구하고 차량의 쏠림이 발생하는 경우 랙바의 위치를 감지하여 차량의 직진 주행할 수 랙바의 위치를 보상하는 MDPS의 쏠림 보상 시스템 및 방법에 관한 것이다. 본 발명에 따른 MDPS의 쏠림 보상 시스템은, 차량(1)의 MDPS(Motor Driven Power Steering)에서 스티어링 휠(11)의 위치와 상기 차량(1)의 조향륜(W)의 방향을 제어하는 랙바(16)의 위치를 감지하고, 상기 스티어링 휠(11)의 위치와 상기 랙바(16)의 위치를 비교하여, 상기 스티어링 휠(11)이 중립(직진 주행으로 조향)인 상태에서 상기 랙바(16)의 위치가 중립이 아닌 것으로 판단되면, 상기 랙바(16)가 중립 위치로 이동하도록 제어하는 제어부(20)를 포함한다.
