PROBLEM TO BE SOLVED: To perform the assist of the torque of an electric motor, and to smoothly perform gear change operation when the gear change operation is performed while performing the synchronization of rotation speed of a transmission input shaft by using the torque of an internal combustion engine, in a power transmission control device which is applied to a hybrid vehicle with an ATM.SOLUTION: At a requirement of gear change to a non-synchronized stage, engagement with a sleeve is released, a neutral stage is obtained, and torque assist by MG torque Tm is performed by OUT connection (t1 to t3). In a joined state of a clutch, EG torque Te is feedback-controlled so that rotation speed Ni of a transmission input shaft coincides with a "synchronization rotation speed" (t3 to t4). In a state that the Te is adjusted to a "synchronization requirement value" so that the synchronization of the Ni is maintained (on and after t4), the Te is temporarily adjusted to a value which is transited to an "engagement release direction" from a "synchronization requirement value" in place of the "synchronization requirement value".

    【課題】AMT付ハイブリッド車両に適用される動力達制御装置であって、電動機トルクのアシストが実行され、且つ、内燃機関トルクを利用して変速機入力軸の回転速度の同期が実行されながら変速作動がなされる場合において、変速作動をスムーズに行うこと。【解決手段】ノンシンクロ段への変速要求時、変速前に噛み合っていた遊転ギヤとスリーブとの係合を解除してニュートラル段が実現されるとともに、OUT接続にてMGトルクTmによるトルクアシストが実行される(t1〜t3)。クラッチの接合状態で、変速機入力軸の回転速度Niが「同期回転速度」に一致するようにEGトルクTeがフィードバック制御される(t3〜t4)。Niの同期が維持されるようにTeが「同期要求値」に調整された状態で(t4以降)、Teが、一時的に「同期要求値」に代えて「同期要求値」から「噛合解除方向」へ変移した値に調整される。【選択図】図7
