Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an internal combustion engine control device that can determine if knock has occurred or not in a period where injector noise and knock coincide with each other.SOLUTION: The internal combustion engine control device determines if knock has occurred or not in a period where vibration of valve closing and opening of a fuel injection valve 5 exists, from the vibration of valve closing and opening of the fuel injection valve 5 that is included in a knock sensor signal output from a knock sensor 8 for detecting vibration of the internal combustion engine 1.SELECTED DRAWING: Figure 3 【課題】インジェクタノイズとノックが重なっている期間において、ノックの有無を判定す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１の振動を検出するノックセンサ８から出力されるノックセンサ信号に含まれる燃料噴射弁５の開弁および閉弁の振動から、燃料噴射弁５の開弁および閉弁の振動が存在する期間におけるノックの有無を判定する。【選択図】図３
