PROBLEM TO BE SOLVED: To provide a control apparatus for a vehicular power transmission device, the apparatus that suppresses the activation of an electric oil even in a case where the engine of the vehicle is stopped, thus suppressing the deterioration of fuel economy of the vehicle system and shortening a period where an operational noise is generated in the oil pump.SOLUTION: In a vehicle in travel, an electric oil pump 42 is activated in a case where a state of lubrication shortage in a power transmission device is predicted, rather than the electric oil pump 42 is always activated, when an engine 12 is stopped, and therefore a state of lubrication shortage in the power transmission device is avoided even in the case of the engine 12 being stopped. Further, the electric oil pump 42 is not activated unnecessarily, and therefore it is possible to suppress deterioration of fuel economy in a vehicle system and suppress discomfort from giving to a passenger of a hybrid vehicle 10 due to generation of an operational noise of the electric oil pump 42.SELECTED DRAWING: Figure 3

    【課題】車両のエンジンが停止している場合であっても、電動式オイルポンプの作動が抑制され、車両システムの燃費の悪化、および、電動式オイルポンプの作動音発生期間が短縮される車両用動力伝達装置の制御装置を提供する。【解決手段】走行中の車両において、エンジン12の停止時に、一律に電動オイルポンプ42が作動させられるのではなく、動力伝達装置内で潤滑油欠乏状態となることが予測される場合に電動式オイルポンプ42が作動させられるので、エンジン12が停止している場合であっても動力伝達装置内で潤滑油欠乏状態が解消されるとともに、不要なときに電動式オイルポンプ42が起動させられないので、車両システムの燃費の悪化が抑制され、電動式オイルポンプ42の作動音が発生してハイブリッド車両10の搭乗者に違和感を与えることも抑制される。【選択図】図3
