Abstract:
A control device for an internal combustion engine includes a throttle valve actuator and circuitry. The circuitry is configured to calculate, based on a target intake air amount, a target recirculated amount of recirculated exhaust gas that is recirculated to an intake passage through an exhaust gas recirculation device, calculate a corrected target recirculated amount based on the target recirculated amount and an exhaust gas recirculated amount change delay in a change in a recirculated amount of the recirculated exhaust gas, calculate a target intake pressure based on the target intake air amount and the corrected target recirculated amount, calculate a target opening degree of the throttle valve based on the target intake air amount and the target intake pressure, and control the throttle valve actuator to drive the throttle valve such that an opening degree of the throttle valve is to be equal to the target opening degree.

Claim (Index 1):
A control device for an internal combustion engine provided with an exhaust gas recirculation device adapted to recirculate exhaust gas to an intake passage comprising:\n target opening calculating means for calculating a target opening of a throttle valve housed in the intake passage; and throttle valve driving means for driving the throttle valve so that the actual opening of the throttle valve corresponds to the target opening; the control device further comprising: target torque calculating means for calculating a target torque of the engine; target intake airflow calculating means for calculating a target intake airflow of the engine based on the target torque; and target intake pressure calculating means for calculating a target intake pressure based on the target intake airflow, wherein the target intake pressure calculating means calculates the target intake pressure by performing an intake pressure change delay process corresponding to a change delay of recirculated exhaust flow that is a flow of exhaust to be recirculated through the exhaust gas recirculation device, and the target opening calculation means calculates the target opening using the target intake airflow and the target intake pressure.
