PROBLEM TO BE SOLVED: To provide a control device for properly controlling an engine in accordance with an intake air flow amount while accurately estimating an actual intake air flow amount in a transient operated condition without determining whether the internal combustion engine is in the transient operated condition or in a steady operated condition. SOLUTION: A flow amount correcting amount DGAIRG which is calculated by multiplying a deviation DGAIR between a corrected intake air flow amount GAIREC and a detected intake air flow amount GAIR by a gain GOB is added to an estimated intake air flow amount GAIRE to calculate an corrected intake air flow amount GAIREC. Thus, the deviation DGAIR is converged to be zero at a converging speed depending on the gain GOB. In the transient condition where there is a detecting delay of an intake air amount sensor, the corrected intake air flow amount GAIREC is changed just as the estimated intake air flow amount GAIRE is changed. In the steady operated condition where there is no influence of the detecting delay of the sensor, it corresponds to the detected intake air flow amount GAIR. COPYRIGHT: (C)2008,JPO&INPIT
