PROBLEM TO BE SOLVED: To provide a power transmission control device capable appropriately engaging a parking lock by stored pressure in an accumulator.SOLUTION: A power transmission apparatus PT includes: a first brake B1; a pressure adjustment valve 19; an accumulator 21; an oil temperature sensor 37; a second solenoid valve 25 for allowing supply of hydraulic oil to a piston 13; and a power transmission control device 14. The power transmission control device 14 includes: memory 14a for storing a hydraulic oil temperature correlated with permissible time that allows releasing of the accumulator 21; and a reception part 14b for receiving a start request. The accumulator 21 is connected so as to supply the first brake B1 and piston 13 with accumulated hydraulic oil. The power transmission control device 14 performs: setting permissible time corresponding to a temperature of the hydraulic oil on the basis of the memory stored in the memory 14a; and supplying the first brake B1 with the hydraulic oil accumulated in the accumulator 21 for the permissible time in the case of receiving restart information for an engine E while a vehicle V performs idling-stop control.SELECTED DRAWING: Figure 3
【課題】適切にアキュームの蓄圧でパーキングロックを掛けることができる動力伝達制御装置を提供する。【解決手段】動力伝達装置PTは、第1ブレーキB1と、調圧弁19と、アキューム21と、油温センサ37と、ピストン13への作動油の供給を許可する第2電磁弁25と、動力伝達制御装置14と、を備える。動力伝達制御装置14は、作動油温とアキューム21の解放を許可する許可時間とを関連付けて記憶するメモリ14aと、始動要求を受信する受信部14bとを備える。アキューム21は、蓄圧した作動油を第1ブレーキB1とピストン13とに供給できるように接続されている。動力伝達制御装置14は、作動油の温度に対応する許可時間をメモリ14aの記憶に基いて設定し、車両Vがアイドルストップ制御を実行中に、エンジンEの再始動情報を受信した場合に、アキューム21で蓄圧された作動油を許可時間の間だけ第1ブレーキB1に供給する。【選択図】図3
