PROBLEM TO BE SOLVED: To provide a controller that can suppress shock which is caused during downshift control by which an engagement-side engagement device is engaged after synchronizing rotation speed of an input shaft of a stepped transmission by increasing torque of an internal combustion engine in a state where the stepped transmission is neutral.SOLUTION: In a case of a speed-change pattern where inner inertia I of a stepped transmission 22 during downshift is large, as requested torque is set so that an increasing gradient of actual torque of an engine 12 is smaller than in a case of speed change pattern where the inner inertia I is small, the actual torque of the engine 12 increases gently and transmission of the torque to an output side of the stepped transmission 22 caused by reaction force of the inner inertial I is suppressed, in the speed-change pattern where the inner inertial I is large. This can suppress rapid change in torque Tout of an output shaft of the stepped transmission 22, so that speed-change shock which is caused during downshift can be suppressed.SELECTED DRAWING: Figure 5

    【課題】有段変速機がニュートラル状態で、内燃機関のトルクアップにより有段変速機の入力軸回転速度を同期させてから係合側係合装置を係合するダウンシフト制御中に発生するショックを抑制する制御装置を提供する。【解決手段】ダウンシフト中における有段変速機22の内部イナーシャIが大きい変速パターンの場合、内部イナーシャIが小さい変速パターンの場合に比べてエンジン12の実トルクの上昇勾配が小さくなるように要求トルクを設定するため、内部イナーシャIの大きい変速パターンでは、エンジン12の実トルクが緩やかに増加し、内部イナーシャIの反力による有段変速機22の出力側へのトルク伝達が抑制される。よって、有段変速機22の出力軸トルクToutの急激な変化が抑制されるので、ダウンシフト中に発生する変速ショックが抑制される。【選択図】図5
