Abstract
A control device for an internal combustion engine, which can accurately estimate an intake air amount introduced from an intake system into an internal combustion engine, is provided. The control device calculates the change amount of an air amount in an upstream section upstream of a throttle valve of the intake system based on the pressure and temperature of air in the upstream section; calculates a throttle passage air amount flowing out to an intake manifold, which is a section downstream of the throttle valve, based on the change amount and an introduced air amount flowing into a supercharger; and calculates the intake air amount based on the throttle passage air amount.
