To effectively use a damper that can change stiffness to reduce vibration of a power transmission device as a whole.SOLUTION: A controller of a power transmission device has a power transmission system transferring torque outputted from a driving power source to a load part, and the power transmission system has a torsional vibration damper which can change torsional stiffness. The controller of the power transmission device includes a controller which controls the torsional stiffness of the torsional vibration damper. The controller includes: a vibration estimation unit (Step S1) which estimates an increase in torsional vibration of the power transmission system; and a torsional stiffness indication unit (Step S3) which instructs, when the vibration estimation unit estimates the increase in torsional vibration, an increase in torsional stiffness of the torsional vibration damper.SELECTED DRAWING: Figure 4
【課題】剛性を変更できるダンパを効果的に使用して動力伝達装置の全体としての振動を低減する。【解決手段】駆動力源が出力したトルクを所定の負荷部分に伝達する動力伝達系統を備え、動力伝達系統に捩り剛性を変更可能な捩り振動ダンパが設けられている動力伝達装置の制御装置であって、捩り振動ダンパの捩り剛性を制御するコントローラを備え、コントローラは、動力伝達系統の捩り振動の増大を推定する振動推定部(ステップS1)と、捩り振動が増大することが振動推定部で推定された場合に、捩り振動ダンパの捩り剛性を増大させる指示を行う捩り剛性指示部(ステップS3)とを備えている。【選択図】図4
