ABSTRACT:
A control apparatus for an internal combustion engine which is capable of performing engine cylinder identification rapidly, easily and inexpensively, while capable of performing a backup control upon occurrence of abnormality in a first signal series containing an angular position signal. The control apparatus includes a first signal detector for generating a first signal series in synchronism with a rotating shaft of the engine, a second signal detector for generating a second signal series in synchronism with the rotating shaft and a control means for controlling parameter on the basis of the first and second signal series. The first signal series includes an angular position signal and a constant level signal corresponding to a reference position for a specific cylinder group. The second signal series includes cylinder identifying signal having a pulse for a given one of the cylinders which differs from those for the other cylinders and a pulse edge falling within the duration of the constant level signal. The control means includes a means for detecting the reference positions for the individual cylinders on the basis of the pulse edge of the cylinder identifying signal and the angular position signal, a means for identifying the cylinders on the basis of the second signal series, a means for arithmetically determining control timings for controlling the parameter on the basis of the results of the cylinder identification and the second signal series, and an abnormality decision means for deciding a fault of the signal series.
