Abstract
There is provided an internal combustion engine control apparatus having an exhaust gas recirculation amount estimation unit that learns the relationship between an exhaust gas recirculation valve opening area calculated by an exhaust gas recirculation valve opening area calculation unit and an opening degree of the exhaust gas recirculation valve and estimates an recirculation amount of exhaust gas utilized in controlling an internal combustion engine, based on the relationship between the exhaust gas recirculation valve opening area and the opening degree of the exhaust gas recirculation valve.
