Abstract: A control for controlling an intake air into an engine is provided. A control valve for adjusting an amount of the intake air into the engine is provided. A desired opening degree of a control valve provided in an intake air passage into the engine is determined based on a clogging coefficient. The clogging coefficient indicates a degree of clogging of the intake air passage. An opening degree of the control valve is controlled to converge to the desired opening degree. The clogging coefficient is updated based on a feedback correction amount for feedback controlling a rotational speed of the engine during idling operation. If a leakage in a blow-by gas passage that is connected between the engine and the intake air passage is detected, the update of the clogging coefficient is prohibited.

Abstract: An atmospheric pressure estimating apparatus which estimates an atmospheric pressure applied to a calculation of control parameters of an internal combustion engine, is provided. An estimated intake air control valve passing air flow rate is calculated based on the estimated atmospheric pressure, the detected intake pressure, and the detected intake air control valve opening. The estimated atmospheric pressure is updated so that the estimated intake air control valve passing air flow rate coincides with the detected intake air control valve passing air flow rate. The estimated intake air control valve passing air flow rate is calculated using the updated estimated atmospheric pressure. The update of the estimated atmospheric pressure and the calculation of the estimated control valve passing air flow rate are sequentially performed. Consequently, the estimated control valve passing air flow rate follows the intake air flow rate, and the estimated atmospheric pressure follows the atmospheric pressure.
