서스펜션 장치(S)는, 차량의 스프링 상부 부재(B)와 스프링 하부 부재(W) 사이에 개재 장착되어 신축 가능한 액추에이터 본체(A)와, 액추에이터 본체(A)로 유체를 공급하여 액추에이터 본체(A)를 신축시키는 펌프(4)를 갖는 액추에이터 장치(AD)와, 펌프(4)의 회전수를 제어하는 컨트롤러(C)를 구비한다. 컨트롤러(C)는, 노면 상태 지표 I를 구하는 노면 상태 지표 취득부(41)와, 노면 상태 지표 I에 기초하여 펌프(4)의 목표 회전수 Nref를 결정하는 목표 회전수 결정부(43)를 갖는다.

    A suspension device (S) includes an actuator device (AD) provided with an extensible/contractible actuator body (A) interposed between a sprung member (B) and an unsprung member (W) of a vehicle, a pump (4) that supplies fluid to the actuator body (A) to extend or contract the actuator body (A), and a controller (C) that controls a rotation number of the pump (4). The controller (C) has a road surface state index obtainment unit (41) that obtains a road surface state index (I) and a target rotation number determination unit (43) that determines a target rotation number (Nref of the pump (4) on the basis of the road surface state index (I).
