摘要： 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.

摘要： A valve timing control apparatus for an internal combustion engine can be improved in accuracy in the detection of valve timing (cam angles). A crank angle sensor generates a crank angle signal in the form of a train of pulses. Cam angle changing parts change phases of camshafts relative to a crankshaft. Cam angle sensors generate cam angle signals. A reference crank angle detection part detects reference crank angles based on the crank angle signal. Cam angle calculation parts calculate the cam angles of the camshafts based on the crank angle signal and the cam angle signals. A cam angle control part controls the relative phases of the camshafts to the crankshaft so as make them coincide with target cam angles corresponding to operating conditions of the engine. A cam angle calculation part calculates the cam angles by counting the number of pulses of the crank angle signal.
