PROBLEM TO BE SOLVED: To improve the fuel economy of a vehicle that includes a rotary electric machine and a staged transmission and executes an unmanned automatic operation.SOLUTION: A shift control apparatus, incorporated in a vehicle 100 including a power transmission mechanism 110 functioning as a staged transmission for changing speed of rotary power transmitting from an engine 101 and the like, thus outputting the power toward a drive wheel 109, and rotary electric machines 103, 105 capable of inputting and outputting rotary torque between drive wheel side and engine side, executes switch control of the transmission by adjusting hydraulic supplied to a friction engagement element of the power transmission mechanism, and includes a manned automatic operation mode and an unmanned automatic operation mode. Further, when synchronizing rotation speeds of input side and output side of the staged transmission using the rotary torque of a rotary electric machine during switch control of the transmission, the control apparatus, in the unmanned automatic operation mode, increases regenerative power of the rotary electric machine than that in the manned automatic operation mode and adjusts hydraulic pressure to be supplied to the friction engagement element so as to decrease power consumed by the rotary electric machine.SELECTED DRAWING: Figure 1
【課題】回転電機と有段変速機とを備えて無人の自動運転モードを実行する車両の燃費向上を図ること。【解決手段】エンジン101等から伝達される回転動力を変速して駆動輪109側に出力する有段変速機として機能する動力伝達機構110と、駆動輪側やエンジン側との間で回転トルクを入出力可能な回転電機103、105とを備える車両100に搭載され、動力伝達機構の摩擦係合要素への供給油圧を調整して変速段の切換制御を実行する変速制御装置であって、有人自動運転モードと無人自動運転モードとを有して、変速段の切換制御中に、回転電機の回転トルクを利用して有段変速機の入出力側の回転速度を同期させる際に、無人自動運転モードでは、有人自動運転モード時よりも回転電機による回生電力を大きくし、また回転電機による消費電力を小さくするように、摩擦係合要素に供給する油圧を調整する。【選択図】図1
