Claims (1)
- 차속 센서, 조향각 센서, 횡가속도 센서, 요 레이트 센서, 상기 각 센서에서 검출된 각종 차량 상태 정보를 입력받아 적정한 조향 기어비를 설정하고, 이 설정된 조향 기어비에 따른 제어신호를 출력하는 ECU, 상기 ECU에서 출력되는 제어신호에 따라 모터 및 조향 가변 기구를 구동시키기 위한 구동신호를 출력하는 구동 회로부, 운전자의 핸들과 조향 액츄에이터 사이에 구비되고, 상기 구동 회로부에서 출력되는 구동신호에 따라 구동되어 조향 기어비를 가변시켜 주는 모터 및 조향 가변 기구를 포함하여 구성된 AFS 시스템에 있어서,상기 ECU가 상기 차속 센서에서 검출된 차속신호를 로우 패스 필터를 통해 로우 패스 필터링하여 급격한 차속 변화에 따른 차속 신호를 완만한 변화의 차속 신호로 변환하여 나타내고, 이 필터링되어 변환된 차속 신호의 결과값을 이용하여 조향 기어비 선정 맵에서 적정 조향 기어비를 설정하도록 하는 것을 특징으로 하는 능동 전륜 조향 시스템의 조향 제어방법.
