PROBLEM TO BE SOLVED: To provide a control device for damping force variable damper and the like in which a solenoid valve is used to vary a cross sectional area of a channel, and which hardly have a continued large current flowing through the solenoid valve and which hardly cause a coil to be short-circuited.SOLUTION: A control device for damping force variable damper comprises: a target current determination part 161 for determining a target current ITA to be supplied to a solenoid valve which controls a damping force of the damping force variable damper; an upper limit setting part 163 for setting an upper limit value of a current to be supplied to the solenoid valve; a supply current determination part 166 for determining the supply current supplied to the solenoid valve based on the target current ITA and the upper limit value. The upper limit setting part 163 determines the upper limit value based on an actual current value supplied to the solenoid valve and a vehicle speed Vc.SELECTED DRAWING: Figure 8

    【課題】流路の断面積を変化させるために電磁弁を用いた場合に、電磁弁に通電する電流が大きい状態が続きにくく、コイルが短絡しにくい減衰力可変ダンパの制御装置等を提供する。【解決手段】減衰力可変ダンパの制御装置であって、減衰力可変ダンパの減衰力を制御するソレノイドバルブに対して供給する目標電流ITAを決定する目標電流決定部161と、ソレノイドバルブに供給する電流の上限値を設定する上限設定部163と、目標電流ITAおよび上限値からソレノイドバルブに供給する供給電流ITFを決定する供給電流決定部166と、を備え、上限設定部163は、ソレノイドバルブに供給された実電流IMと車両の車速Vcとに基づいて、上限値を決定する減衰力可変ダンパの制御装置。【選択図】図8
