PROBLEM TO BE SOLVED: To provide an attenuation force control device of a suspension which derives an attenuation force control value suitable for suppressing the vibration of a vehicle body, related to the attenuation force control value for controlling a damper.SOLUTION: An attenuation force control device comprises: a displacement correlation amount estimation device 3 for deriving an estimation relative speed yob1 and an estimation relative displacement yob2; and an attenuation force control value calculation device for deciding an attenuation force control value P on the basis of a state variable of a vehicle body and the estimation relative speed yob1. The displacement correlation amount estimation device 3 estimates the estimation relative speed yob1 and the estimation relative displacement yob2 on the basis of the state variable, the attenuation force control value P, and the estimation relative speed yob1 and the estimation relative displacement yob2 which are estimated by the displacement correlation amount estimation device 3 itself.SELECTED DRAWING: Figure 5

    【課題】ダンパーを制御するための減衰力制御値について、車体の振動抑制に好適な減衰力制御値を導出するサスペンションの減衰力制御装置を提供する。【解決手段】減衰力制御装置は、推定相対速度yob1及び推定相対変位yob2を導出する変位関連量推定装置3と、車体の状態変数と推定相対速度yob1とに基づいて減衰力制御値Pを決定する減衰力制御値演算装置とを備える。変位関連量推定装置3は、状態変数と、減衰力制御値Pと、変位関連量推定装置3自身が推定した推定相対速度yob1及び推定相対変位yob2とに基づいて、推定相対速度yob1と推定相対変位yob2とを推定する。【選択図】図5
