ABSTRACT:
An engine control apparatus for an internal combustion engine capable of rapidly and easily identifying engine cylinders with high accuracy, while ensuring a backup control upon occurrence of an abnormality. The control apparatus includes a first signal detector provided in association with a crank shaft for obtaining a first signal series, a second signal detector provided in association with a cam shaft for obtaining a second signal series, and a controller for controlling a parameter involved in engine operation on the basis of each signal series. The first signal series includes an angular position signal and level intervals corresponding to cylinder groups, while the second signal series includes cylinder identifying signal pulses. The pulse identifying a given cylinder has a form which differs from those for the other cylinders. The controller includes a level interval detector for detecting the level intervals on the basis of the first signal series, a reference position detector for detecting reference positions for the individual cylinders on the basis of the first signal series, a cylinder group identifier for identifying groups each comprised of cylinders controlled simultaneously, a cylinder identifier for identifying the cylinders on the basis of the second signal series, a calculator 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 detector for detecting occurrence of abnormality in one of the signal series.
