PROBLEM TO BE SOLVED: To increase precision of abnormality determination of an attenuation force adjusting type damper.SOLUTION: A damper 8 includes: a cylinder 9; a piston 10; a piston rod 11; and an actuator 13. The actuator 13 includes a control valve 13A and a proportional solenoid 13B. A control device 15 supplies solenoid current I to the proportional solenoid 13B and controls the control valve 13A according to the solenoid current I. The control device 15 estimates a solenoid temperature T of each damper 8 from the solenoid current I and compares the solenoid temperatures T of the dampers 8 with each other. The control device 15 determines that one damper 8 is in an abnormal condition when the solenoid temperature T of the one damper 8 is out of a predetermined temperature range with respect to the solenoid temperature T of at least two or more other dampers 8.SELECTED DRAWING: Figure 1

    【課題】 減衰力調整式緩衝器の異常判定精度を高める。【解決手段】 ダンパ8は、シリンダ9と、ピストン10と、ピストンロッド11と、アクチュエータ13とを備える。アクチュエータ13は、制御バルブ13Aと比例ソレノイド13Bを備える。制御装置15は、比例ソレノイド13Bにソレノイド電流Iを供給し、ソレノイド電流Iに応じて制御バルブ13Aを制御する。制御装置15は、各ダンパ8のソレノイド温度Tをソレノイド電流Iから推定し、各ダンパ8のソレノイド温度Tを互いに比較する。制御装置15は、一のダンパ8のソレノイド温度Tが、少なくとも2つ以上の他のダンパ8のソレノイド温度Tに対して所定の温度範囲外のときに、一のダンパ8が異常状態であると判定する。【選択図】 図1
