To effectively suppress rod vibration in a variable attenuation force damper.SOLUTION: A controller of a variable attenuation force damper comprises an attenuation force adjustment unit 45 that adjusts attenuation force generated by a variable attenuation force damper 1, and a pressure control unit 46 that controls pressure in a high pressure chamber in a cylinder 2. The pressure control unit acquires the pressure in the high pressure chamber, and controls the pressure in the high pressure chamber so that the pressure in the high pressure chamber becomes equal to or less than a threshold value at the timing when the movement direction of a piston is switched.SELECTED DRAWING: Figure 6
【課題】減衰力可変ダンパにおけるロッド振動を効果的に抑制する。【解決手段】減衰力可変ダンパの制御装置は、減衰力可変ダンパ1によって生成される減衰力を調整する減衰力調整部45と、シリンダ2内の高圧室の圧力を制御する圧力制御部46とを備える。圧力制御部は、高圧室の圧力を取得し、ピストンの移動方向が切り替わるタイミングにおいて高圧室の圧力が閾値以下になるように高圧室の圧力を制御する。【選択図】図6
