<p><P>PROBLEM TO BE SOLVED: To provide an internal combustion engine system control device, more accurately controlling an internal combustion engine system having a supercharger by inexpensive device constitution. <P>SOLUTION: A provisional intake air amount, that is an in-cylinder intake air flow rate when it is assumed that a supercharging pressure is identical to a supercharging pressure calculation value during steady-state operation, is calculated based on a relationship between an intake air amount and a supercharging pressure steady-state, that is a relationship between an in-cylinder intake air flow rate and a supercharging pressure during steady-state operation in the internal combustion engine system, and a supercharging pressure calculation value calculated by a supercharging pressure calculation means. A rotation number of a compressor is estimated based on a relationship between an intake air amount and a rotation number steady-state, that is a relationship between an in-cylinder intake air flow rate and a rotation number of the compressor during steady-state operation, an in-cylinder intake air flow rate calculated by an in-cylinder intake air flow rate calculation means, and a provisional intake air amount. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
