PROBLEM TO BE SOLVED: To shorten the time required to complete a gear change action at the time of performing a gear change manipulation irrespective of a gradient of a traveling road.SOLUTION: An automatic gear change control system of a hybrid vehicle has a clutch 26, electric motor 31, and mechanical transmission 10 connected in that order to an internal combustion engine 21. Gear change control means 36 is included to control the electric motor 31 before gears are engaged with one another after the gears are disengaged from one another when the mechanical transmission 10 is manipulated in order to change a gear ratio, so that the rotating speed of an input shaft of the mechanical transmission 10 can approach to a rotating speed at which the gears can be engaged with one another. The automatic gear change control system further includes road gradient detection means 37 that detects the gradient of a traveling road, and acceleration/deceleration detection means 40 that detects the acceleration or deceleration of a vehicle. When the gear ratio is changed, if the road gradient detection means 37 detects a gradient that falls outside a predetermined range, the gear change control means 36 controls the electric motor on the basis of the acceleration or deceleration, which is detected by the acceleration/deceleration detection means, so that the rotating speed of the input shaft will approach to an offset rotating speed which is deviated by a predetermined value in a direction in which the rotating speed increases or decreases from the rotating speed at which the gears can be engaged with one another.SELECTED DRAWING: Figure 1

    【課題】走行する道路の勾配に係わらず、変速操作時における変速動作完了までの時間を短縮する。【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の回転速度をギヤ入れ可能な回転速度に近づくように電動機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と車両の加速又は減速を検出する加減速検出手段40が設けられ、変速制御手段36は、変速操作時に道路勾配検出手段37が所定の範囲を外れる勾配を検出すると、加減速検出手段が検出する加速又は減速に基づいてギヤ入れ可能な回転速度から回転速度が増加又減少する方向に所定値ずれたオフセット回転速度にインプットシャフトの回転速度が近づくように電動機を制御する。【選択図】図1
