Abstract
Provided is an internal combustion engine control device capable of appropriately correcting a flow rate of EGR gas. Therefore, an internal combustion engine control deviceincludes moisture amount calculation unitsand, a dew condensation calculation unit, and an EGR correction unit. The moisture amount calculation unitcalculates a total moisture amount contained in the mixed gas. The dew condensation calculation unitcalculates a dew condensation generation amount WQcon in an intercooler based on the total moisture amount. The EGR correction unitcorrects a flow rate of the EGR gas based on the dew condensation generation amount WQcon.
