INTERNAL COMBUSTION DEVICE, CONTROL METHOD THEREOF, AND VEHICLE

Upon no detection of the closing abnormality where the EGR valve does not become in the totally closed state (when the flag Fa is value '0'), the engine is controlled using the target fuel injection amount Qf* obtained from the correction of the basic fuel injection amount Qftmp toward the increase direction, in the case that the engine is operated together with the recirculation of the exhaust in the preset high-load operation range (when the flag Fi is '1') (S220, S230, S250 and S260). Upon detection of the closing abnormality (when the flag Fa is value '1'), the engine is controlled using the target fuel injection amount Qf* obtained from the correction of the basic fuel injection amount Qftmp toward the increase direction, in the case that the engine is operated together with the recirculation of the exhaust in the whole range that the engine is operable together with the recirculation of the exhaust (S220, S250, S260).
