Abstract:
Provided is a control device for an internal combustion engine, which can ensure a stable combustion state of the internal combustion engine even under a high-humidity environment condition, thereby improving the merchantability. The control device for the internal combustion engine includes an ECU (electronic control unit). The ECU calculates a basic target EGR amount according to an operating state of the internal combustion engine, calculates a water vapor amount in air drawn into an intake passage of the internal combustion engine, calculates an EGR conversion amount by using the water vapor amount, calculates a target EGR amount by subtracting the EGR conversion amount from the basic target EGR amount, and controls internal EGR and external EGR of the internal combustion engine by using the target EGR amount.

Claim (Index 5):
A control device for an internal combustion engine, comprising:\n a basic target EGR amount calculation part calculating, according to an operating state of the internal combustion engine, a basic target EGR amount that is a basis of a target value of an EGR amount, the EGR amount being an amount that causes an exhaust gas inside an exhaust passage of the internal combustion engine to recirculate to an intake side of the internal combustion engine; a water vapor parameter acquiring part acquiring a water vapor parameter representing a ratio or an amount of water vapor in intake air, the intake air being air drawn into an intake passage of the internal combustion engine; a water vapor amount calculation part calculating a water vapor amount, which is the amount of the water vapor, by using the water vapor parameter; an EGR conversion amount calculation part calculating, by multiplying the water vapor amount by a conversion factor greater than 1, an EGR conversion amount obtained by converting the water vapor amount into an EGR amount; a target EGR amount calculation part calculating a target EGR amount by correcting the basic target EGR amount by the EGR conversion amount; and a control part controlling operation of the internal combustion engine by using the target EGR amount.
