Beschreibung
Zusammenfassung:	A control apparatus for an internal combustion engine, which is capable of, when controlling a variable intake cam phase mechanism and a variable exhaust cam phase mechanism, ensuring a stable combustion of a mixture and improving the drivability, even when one of the two is in a failure state. The control apparatus includes an ECU. The ECU calculates an intake cam phase and an exhaust cam phase, determines, based on the calculated intake cam phase and exhaust cam phase, whether or not there has occurred a failure state of one of the mechanisms, in which the valve overlap period becomes longer than during a normal time, and controls, when it is determined that there has occurred the failure state of the one mechanism, the other mechanism such that the valve overlap period becomes shorter.
