PROBLEM TO BE SOLVED: To appropriately adjust a current value supplied to a solenoid that controls damping force of suspension.SOLUTION: A suspension control device (600) comprises: a target current setting part (631A); a limit current setting part (632A); a current sensor (633A) that detects a current value supplied to a solenoid; a duty ratio setting part (634A) that sets a duty ratio with reference to a target current value, a current upper limit value, and a current value; and an output circuit (635A) that supplies to the solenoid a current according to the duty ratio and a power supply voltage. The limit current setting part changes the current upper limit value according to the duty ratio.SELECTED DRAWING: Figure 6

    【課題】サスペンションの減衰力を制御するソレノイドに供給される電流値を適切に調整する。【解決手段】目標電流設定部(631A)と、制限電流設定部(632A)と、ソレノイドに供給の電流値を検出する電流センサ(633A)と、目標電流値、電流上限値、電流値を参照して、デューティ比を設定するデューティ比設定部(634A)と、デューティ比、電源電圧に応じた電流をソレノイドに供給する出力回路(635A)と、を備え、制限電流設定部は、デューティ比に応じて、電流上限値を変更するサスペンション制御装置(600)。【選択図】図6
