    • Provided is a fuel injection control device for an internal combustion engine capable of setting an overexcitation current time period which allows injectors to be reliably driven even when a fuel pressure sensor is in an abnormal state. A fuel supply control portion is equipped with an injector-valve opening signal generating unit, a first driving current supply signal generating unit, a first driving current supplying unit, a second driving current supplying unit, and a fuel pressure sensor malfunction detecting unit. When a malfunction in the fuel pressure sensor is detected, the first driving current supply signal generating unit sets a first driving current supply time period to a fixed time period which allows injectors to be opened even when a fuel pressure in the internal combustion engine is at its maximum.

    • An internal combustion engine control apparatus can reliably detect abnormality in a crank angle position signal to ensure a fail safe function upon occurrence of the abnormally. A fuel injection signal and an ignition signal is generated based on the result of cylinder identification performed by a cylinder identification part and the crank angle position of the crank angle position signal. An abnormality determination part determines whether the crank angle position signal is abnormal. The cylinder identification part includes a cylinder identification resetting part for resetting the current content of the cylinder identification performed by the cylinder identification part upon determination of abnormality. The cylinder identification resetting part includes a fuel injection and ignition signal stopping part for stopping the fuel injection signal and the ignition signal, and a cylinder identification information clearing part for clearing previous cylinder identification information earlier than the last crank angle position signal upon determination of abnormality.
