In a case where fuel injection system abnormality is detected, and fuel supply stop processing is carried out against the abnormality, since a judgment is made using a misfire judgment, in a case where the misfire judgment is carried out in a periodic measurement system, the reliability is low at the time of a periodic variation or in a low rotation region, and in a case where it is carried out in an ion detection system, the cost increases, and the calculation load of an internal combustion engine control apparatus by the misfire judgment processing increases. A control apparatus for a vehicular internal combustion engine of the invention includes an injector drive abnormality judgment unit to judge, based on an injector drive confirmation signal, drive abnormality of an injector corresponding to the injector drive confirmation signal, and the injector drive abnormality judgment unit judges abnormality of the injector drive confirmation signal based on a state of the injector drive confirmation signal.
