ABSTRACT:
An intake air pressure P1and a target control value S1under the condition that the internal combustion engine is in a steady operating state and the condition that the turbocharger has its supercharging efficiency set to a ratio according to the engine operating state are estimated based on engine parameters, and an intake air pressure P2and a target control value S2under the condition that the internal combustion engine is in the steady operating state and the condition without supercharging by the turbocharger are estimated based on the engine parameters. A target control value S0associated with an actual intake air pressure P0under the condition that the internal combustion engine is in a transient operating state is calculated by performing interpolation on the target control values S1, S2based on a relation between the intake air pressures P1, P2and the actual intake air pressure P0.
