Summary:To suppress the occurrence of problems in an actuator when there is an abnormality in oil.SOLUTION: An oil sensor 50 detects at least one of viscosity, kinematic viscosity, temperature, and dielectric constant of oil. An abnormality determination unit 72 can determine whether or not there is abnormality in the oil based on the detection value of the oil sensor 50. An operation control unit 76 controls the operation of an actuator A. When the abnormality determination unit 72 determines that there is no abnormality in the oil, the operation control unit 76 controls the actuator A by predetermined normal control. When the abnormality determination unit 72 determines that there is an abnormality in the oil, the operation control unit 76 controls the actuator A by the oil abnormality time control different from the normal control.SELECTED DRAWING: Figure 3 【課題】オイルに異常があるときに、アクチュエータに問題が生じることを抑制する。【解決手段】オイルセンサ50は、オイルの、粘度、動粘度、温度、および誘電率の少なくともいずれかを検出する。異常判定部72は、オイルセンサ50の検出値に基づいてオイルの異常の有無を判定可能である。作動制御部76は、アクチュエータAの作動を制御する。オイルに異常がないと異常判定部72が判定した場合、作動制御部76は、所定の通常制御によりアクチュエータAを制御する。オイルに異常があると異常判定部72が判定した場合、作動制御部76は、通常制御とは異なるオイル異常時制御によりアクチュエータAを制御する。【選択図】図3
