PROBLEM TO BE SOLVED: To reliably complete gear-meshing at a down-shift even in the case of the rotation speed of an output shaft oscillating.SOLUTION: A hybrid-vehicular automatic transmission control apparatus includes: a clutch 26, a motor 31 and a mechanical transmission 10 connected, in the aforementioned order, to an internal combustion engine 21; and transmission control means 36 for controlling the motor 31 so that a rotation speed of an input shaft 2 of the mechanical transmission 10 is set at a rotation speed enabling gear-meshing before gear-meshing after a gear-un-meshing when performing a shift operation of the mechanical transmission 10. Road inclination detection means 37 is disposed for detecting an inclination of a travel road, and when the road inclination detection means detects an uphill of an inclination equaling to or exceeding a given value when a down-shift is performed, the transmission control means controls the motor 31 so as to set a rotation speed of the input shaft at a control rotation speed that is produced by subtracting a given specified value from the rotation speed of the input shaft 2 at the time of gear-un-meshing.SELECTED DRAWING: Figure 5

    【課題】アウトプットシャフトの回転速度が振動する場合であっても、シフトダウン時におけるギヤ入れを確実に完了させる。【解決手段】ハイブリッド車両の自動変速制御装置は、内燃機関21にクラッチ26と電動機31と機械式変速機10がこの順序で接続される。機械式変速機10の変速操作時に、そのギヤ抜き後ギヤ入れ前に機械式変速機10のインプットシャフト2の回転速度をギヤ入れ可能な回転速度にするように電動機31を制御する変速制御手段36を備える。走行道路の勾配を検出する道路勾配検出手段37が設けられ、変速制御手段は、シフトダウン時に道路勾配検出手段が所定値以上の勾配の上り坂であることを検出すると、インプットシャフトの回転速度をギヤ抜き時のインプットシャフト2の回転速度から所定の規定値を減じた制御回転速度にするように電動機31を制御する。【選択図】図5
