Summary: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
