Classification: CPC F  Y | IPC F

Claim 0:
1. An internal combustion engine control device that controls an internal combustion engine including an intercooler that cools intake air and an EGR flow path pipe that recirculates a part of exhaust gas in an exhaust path to an upstream side of the intercooler as EGR gas,
the internal combustion engine control device comprising:
a moisture amount calculation unit configured to calculate a total moisture amount contained in a mixed gas obtained by mixing fresh air flowing into the intercooler and the EGR gas;
a dew condensation calculation unit configured to calculate a dew condensation generation amount in the intercooler based on the total moisture amount calculated by the moisture amount calculation unit; and
an EGR correction unit configured to correct a flow rate of the EGR gas to be recirculated based on the dew condensation generation amount calculated by the dew condensation calculation unit,
wherein the EGR correction unit includes an EGR gas correction table in which an EGR gas correction amount for correcting the EGR gas according to the dew condensation generation amount is set.
