INTERNAL COMBUSTION ENGINE SYSTEM CONTROL DEVICE

摘要

The device of the invention is provided with models (M2 to M7) constructed based on physical laws. Compressor outflow flow rate calculation means (M4) calculates the flow rate of air that flows out of a compressor (39b) based on a relationship between an in-cylinder intake air flow rate during steady-state operation in an internal combustion engine system and supercharging pressure, which is pressure of air compressed by the compressor (39b), and a value of the in-cylinder intake air flow rate calculated by in-cylinder intake air flow rate calculation means (M3).
