PROBLEM TO BE SOLVED: To provide a control device for an engine with a turbocharger, which can control the engine so as to accurately obtain a vehicle behavior intended by a driver while suppressing deterioration of acceleration response in the engine having the turbocharger.SOLUTION: A control device for an engine with a turbocharger includes: a basic target torque determination section (61) for determining basic target torque on the basis of a vehicle operating state including an operation of an accelerator pedal; a torque reduction quantity determination section (63) for determining torque reduction quantity on the basis of a vehicle operating state excluding the operation of the accelerator pedal; a final target torque determination section (65) for determining final target torque on the basis of the basic target torque and the torque reduction quantity; and an engine control section (69) for controlling the engine so as to output the final target torque and controlling the turbocharger on the basis of the final target torque. The engine control section (69) restricts the control of the turbocharger (5) that is performed in accordance with a change of the final target torque corresponding to a change of the torque reduction quantity.SELECTED DRAWING: Figure 3

    【課題】ターボ過給機を有するエンジンにおいて、加速レスポンスの悪化を抑制しつつ、ドライバの意図した車両挙動を正確に実現するようにエンジンを制御することができる、ターボ過給機付きエンジンの制御装置を提供する。【解決手段】ターボ過給機付きエンジンの制御装置は、アクセルペダルの操作を含む車両の運転状態に基づき基本目標トルクを決定する基本目標トルク決定部(61)と、アクセルペダルの操作以外の車両の運転状態に基づきトルク低減量を決定するトルク低減量決定部(63)と、基本目標トルクとトルク低減量とに基づき最終目標トルクを決定する最終目標トルク決定部(65)と、最終目標トルクを出力させるようにエンジンを制御し、最終目標トルクに基づきターボ過給機を制御するエンジン制御部(69)とを有し、エンジン制御部(69)は、トルク低減量の変化に対応する最終目標トルクの変化に応じたターボ過給機(5)の制御を制限する。【選択図】図3
