PROBLEM TO BE SOLVED: To provide a parking mechanism capable of easily determining abnormality.SOLUTION: A control device controls a parking mechanism 100 including: a park piston 3 having a pressure receiving surface configured to receive working hydraulic pressure, formed with a groove, and integrally moving with a parking rod 5 according to the working hydraulic pressure; and a lock mechanism 7 capable of regulating movement of the park piston 3 by engaging an engagement part 71 with a groove 32. The control device includes a control unit 9 configured to increase/decrease the working hydraulic pressure to determine abnormality of the parking mechanism 100 in a state of inserting the engagement part 71 into the groove.SELECTED DRAWING: Figure 2
【課題】異常判定を容易に行うパーキング機構を提供する。【解決手段】作動油圧がかかる受圧面を有し、溝が形成され、作動油圧に応じてパーキングロッド5と一体的に移動するパークピストン3と、係合部71を溝32に係合することでパークピストン3の移動を規制可能なロック機構7とを備えたパーキング機構100を制御する制御装置であって、係合部71を溝に挿入した状態で、作動油圧を増減することで、パーキング機構100の異常判定を行う制御部9を備える。【選択図】 図2
