본 발명은 MDPS(Motor Driven Power Steering) 시스템에 있어서, 차량의 서스펜션 스트로크를 측정하는 차고센서; 상기 MDPS의 스티어링 앵글을 측정하는 조향각센서; 상기 측정된 서스펜션 스트로크 및 상기 스티어링 앵글이 기설정 값을 만족하면 상기 MDPS의 출력을 감소시키는 제어부; 를 포함하는 MDPS 시스템을 포함하여, 차량이 정차중이거나 저속으로 주행중 스티어링을 작동범위 한계까지 작동할 때에도 랙 스트로크 끝단 전부터 MDPS의 어시스트력을 줄여줌으로써 랙 엔드의 충격이 방지되기 때문에 충격이나 노이즈가 억제되는 효과가 있다.

    According to the present invention, a motor driven power steering (MDPS) system comprises: a garage sensor for measuring the suspension stroke of a vehicle; a steering angle sensor for measuring a steering angle of the MDPS; and a control unit for reducing the output of the MDPS when the measured suspension stroke and the steering angle satisfy a preset value. By including the MDPS, the impact of the rack end is prevented by reducing the assist force of the MDPS even before the end of the rack stroke, even when the vehicle is operated to the operating range limit while driving at rest or at low speed.
