Abstract

본 발명은 가변 감쇄력 특성을 제공하기 위해 차량의 탄성 및 비탄성 질량체 사이에 제공되어진 적어도 하나의 완충기를 제어해주는 현가 제어 시스템에 관한 것이다. 제어 시스템은 감지왼 조향각을 나타내는 전기 신호상에 중첩된 소음을 여과하기 위한 저역 통과 필터를 포함한다. 소음 제거 조향각 표시 힌호를 최적 감쇄력 특성을 제공하기 위해 감지된 자향 동작을 기초로 하여 완충기를 제어해주는 정상 제어 모드와 정상 제어 모드에서 제공된 것보다 더 큰 감쇄력 특성을 제공하기 위해 소음 제거 차량 조향각 표시 신호를 기초로 하여 완충기를 제어해주는 롤 제어 모드에서 작동 가능한 제어 유니트로 제공되어 진다. 제어 유니트는 소음 제거 조향각 표시 신호가 소정의 제1한계값을 초과할 때에 롤 제어 모드에서 작동한다.이 작동은 소음 제거 조향각 표시 신호가 그 피크값과 정비례하여 설정된 제2한계값 아래로 감소하고 나서 소정의 시간 후에 롤 제어 모드로부터 정상 제어 모드로 변화되어 진다.
