  "textContent": "The present invention relates to a control unit of an internal combustion engine capable of performing a coordinate control of an exhaust gas recirculation (hereinafter abbreviated as \"EGR\") gas supply amount by an EGR apparatus and a supercharging amount by a supercharger provided with a variable flow mechanism. The control unit comprises: a state quantity estimation section (77) for calculating an in-cylinder oxygen excess ratio based on an operating state of the internal combustion engine; and a switching part (81) for switching the respective opening degree commands for the EGR valve and the variable flow mechanism of the supercharger so that the opening degree of the EGR valve and the opening degree of the variable flow mechanism become smaller than in a normal state when the internal combustion engine is determined to be in the transient state based on the calculated in-cylinder oxygen excess ratio.",
