PROBLEM TO BE SOLVED: To provide a suspension device and a suspension control device which can improve ride comfort in a vehicle without using equipment exhibiting high response.SOLUTION: A suspension device S1 comprises an actuator A capable of generating thrust and a controller C1. The controller C1 comprises: a first vibration suppressing force calculating portion 12 that determines first vibration suppressing force F1 from speed Vb in a vertical direction of a sprung member B; a second vibration suppressing force calculating portion 13 that determines second vibration suppressing force F2 from speed Vw in a vertical direction of an unsprung member W or relative speed Vs of the sprung member B and the unsprung member Vw; a low-pass filter L1 which has a crossover frequency ωc between a sprung resonant frequency ωb and an unsprung resonant frequency ωw and processes a signal Fw in a step for determining the second vibration suppressing force F2 by the second vibration suppressing force calculating portion 13; and a target thrust calculating portion 15 which determines target thrust of the actuator A on the basis of the first vibration suppressing force F1 and the second vibration suppressing force F2.SELECTED DRAWING: Figure 1

    【課題】高応答の機器を用いずとも車両における乗り心地を向上させることが可能なサスペンション装置およびサスペンション制御装置を提供することである。【解決手段】サスペンション装置S1は、推力を発生可能なアクチュエータAと、コントローラC1とを備え、コントローラC1は、ばね上部材Bの上下方向の速度Vbから第一振動抑制力F1を求める第一振動抑制力演算部12と、ばね下部材Wの上下方向の速度Vw或いはばね上部材Bとばね下部材Vwとの相対的な速度Vsから第二振動抑制力F2を求める第二振動抑制力演算部13と、ばね上共振周波数ωbとばね下共振周波数ωwとの間に折れ点周波数ωcを持ち、第二振動抑制力演算部13で第二振動抑制力F2を求める過程の信号Fwを処理するローパスフィルタL1と、第一振動抑制力F1と第二振動抑制力F2とに基づいてアクチュエータAの目標推力を求める目標推力演算部15とを備えた。【選択図】図1
