CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

To reduce motor torque required for motoring for starting an internal combustion engine without deteriorating startability of the internal combustion engine at low-temperature start of the internal combustion engine.SOLUTION: A control device for an internal combustion engine includes: a temperature acquisition section 55 that acquires a temperature of the internal combustion engine 1 when start of the internal combustion engine is requested; a motoring execution section 56 that executes motoring of the internal combustion engine by using a motor 32 when start of the internal combustion engine is requested; and a cylinder internal pressure control section 58 that controls cylinder internal pressure of the internal combustion engine during motoring on the basis of the temperature of the internal combustion engine. When the temperature of the internal combustion engine is equal to or lower than a predetermined threshold temperature, the cylinder internal pressure control section executes cylinder internal pressure increase control for increasing the cylinder internal pressure compared to when the temperature of the internal combustion engine is higher than the threshold temperature, from start of the motoring.SELECTED DRAWING: Figure 8 【課題】内燃機関の低温始動時に、内燃機関の始動性を悪化させることなく、内燃機関を始動させるためのモータリングに必要なモータトルクを低減する。【解決手段】内燃機関の制御装置は、内燃機関１の始動が要求されたときの内燃機関の温度を取得する温度取得部５５と、内燃機関の始動が要求されたときに、モータ３２により内燃機関のモータリングを実行するモータリング実行部５６と、内燃機関の温度に基づいてモータリング中の内燃機関の筒内圧を制御する筒内圧制御部５８とを備える。筒内圧制御部は、内燃機関の温度が所定の閾値温度以下である場合には、内燃機関の温度が閾値温度よりも高い場合と比べて筒内圧を増大させる筒内圧増大制御をモータリングの開始時点から実行する。【選択図】図８
