To provide a controller of a vehicle with a multistage automatic transmission capable of performing original downshift according to decrease of vehicle speed while continuing a combustion stopping state of an engine till stop of the vehicle during deceleration traveling to stop.SOLUTION: A controller of a vehicle with a multistage automatic transmission is given in which a combustion stopping control during deceleration is performed to stop combustion of an engine 1 when satisfying prescribed condition during traveling of the vehicle, combustion restoration due to decrease of engine rpm is regulated while performing the combustion stopping control during deceleration, and when the engine rpm becomes a prescribed rpm N0 while executing the combustion stopping control during deceleration, a motor 10 controls rotary drive of the engine 1 to keep the engine rpm to be the prescribed rpm N0 till completing downshift to a prescribed shift stage.SELECTED DRAWING: Figure 6
【課題】停車に向けた減速走行が行われるとき、エンジンの燃焼停止状態を停車するまで継続させながら、車速の低下に応じた本来のシフトダウンを実現し得る多段自動変速機付車両の制御装置を提供する。【解決手段】車両走行中に所定条件が成立したとき、エンジン1の燃焼を停止させる減速時燃焼停止制御を実行し、前記減速時燃焼停止制御の実行中において、エンジン回転数の低下による燃焼復帰を規制し、前記減速時燃焼停止制御の実行中において、エンジン回転数が所定回転数N0まで低下したときから、所定変速段へのシフトダウンが完了するまでの間、エンジン回転数が所定回転数N0に維持されるように、モータ10によるエンジン1の回転駆動を制御する。【選択図】図6
