PROBLEM TO BE SOLVED: To provide a controller of an internal combustion engine that in an idle state of the internal combustion engine, suppresses reduction of the actual rotational frequency of an engine even when auxiliary machines, in which driving torque necessary for obtaining constant output by change of humidity changes, actuate, and that can improve fuel economy in the idle state.SOLUTION: A controller of an internal combustion engine corrects ignition timing on the basis of the humidity of air suctioned into the internal combustion engine and the operation state of an auxiliary machine driven by utilizing the driving torque of the internal combustion engine, and controls at least one of a suctioned air amount and a fuel injection amount on the basis of the corrected ignition timing.SELECTED DRAWING: Figure 3 【課題】内燃機関（エンジン）がアイドル状態の時に、湿度の変化によって一定の出力を得るために必要な駆動トルクが変化する補機類が作動しても、エンジンの実回転数の低下を抑制するとともに、アイドル状態の時の燃費の向上を図ることのできる内燃機関の制御装置を提供する。【解決手段】内燃機関に吸入される空気の湿度及び内燃機関の駆動トルクを利用して駆動される補機の動作状態に基づいて点火時期を補正すると共に、補正後の点火時期に応じて吸入空気量及び燃料噴射量の少なくとも一方を制御する。【選択図】図３
