Claims (3)
- 차량의 차체와 차축 사이에 장착되어 액추에이터에 의해 감쇠력을 제어할 수 있는 충격 흡수기와, 노면 상태에 대응한 신호를 출력하는 노면 상태 검출 수단과, 이 노면 상태 검출 수단의 출력 신호로부터 적어도 2개의 다른 진동 성분을 추출하는 추출 수단과, 그 진동 성분의 레벨이 소정치를 초과하였을 때에 상기 각 진동 성분마다 미리 설정된 소정의 감쇠력 제어를 행하는 감쇠력 제어 수단을 포함하며,상기 감쇠력 제어 수단은 상기 각 진동 성분 중 적어도 2개의 진동 성분의 레벨이 동시에 상기 각 소정치를 초과하였을 때에 미리 정해진 우선순위에 근거하여 감쇠력을 제어하는 것을 특징으로 하는 서스펜션 제어 장치.
- 제1항에 있어서, 상기 감쇠력 제어 수단은 저주파의 진동 성분에 대응한 감쇠력 제어에 우선하여 고주파의 진동 성분에 대응한 감쇠력 제어를 행하는 것을 특징으로 하는 서스펜션 제어 장치.
- 제1항에 있어서, 상기 감쇠력 제어 수단은 차속이 낮은 경우에는 저주파의 진동 성분에 대응한 감쇠력 제어에 우선하여 고주파의 진동 성분에 대응한 감쇠력 제어를 행하고, 차속이 높은 경우에는 고주파의 진동 성분에 대응한 감쇠력 제어에 우선하여 저주파의 진동 성분에 대응한 감쇠력 제어를 행하는 것을 특징으로 하는 서스펜션 제어 장치.
