Zusammenfassung:PROBLEM TO BE SOLVED: To enable actual operation restart of at least one resting cylinder earlier while minimizing the occurrence of shock in a vehicle, in the cylinder resting operation of an engine when an operation restart requirement is generated to restart the operation of at least one resting cylinder before executing a reduction in the output torque of the engine at the time of executing the shift-up of an automatic transmission.SOLUTION: In the cylinder resting operation of an engine 1 when the operation restart requirement is generated before executing a reduction in the output torque of the engine 1 at the time of executing the shift-up of an automatic transmission 3, torque reduction restricting means (a torque reduction restricting part 50c) restricts a reduction in the output torque of the engine 1 until a timing for actual operation restart of at least one resting cylinder.SELECTED DRAWING: Figure 1 【課題】エンジンの気筒休止運転中において、自動変速機のシフトアップの実行時におけるエンジンの出力トルクの低下の実行前に、少なくとも1つの休止気筒を作動復帰させる作動復帰要求が発生したときに、車両にショックが出来る限り生じないようにしつつ、少なくとも1つの休止気筒の実際の作動復帰を早期に行えるようにする。【解決手段】エンジン1の気筒休止運転中において、自動変速機3のシフトアップの実行時におけるエンジン1の出力トルクの低下の実行前に、上記作動復帰要求が発生したときに、トルク低下制限手段(トルク低下制限部50c)により、上記少なくとも1つの休止気筒の実際の作動復帰のタイミングまで、エンジン1の出力トルクの低下を制限する。【選択図】図1
