Abstract
The control apparatus for an internal combustion engine includes a throttle opening learning value calculation unit for calculating a throttle opening learning value based on a deviation between a target throttle opening and a learning throttle opening, controls the throttle opening by a learning corrected target throttle opening obtained by correcting the target throttle opening with the throttle opening learning value, and updates and stores a real-time learning value and a long time learning value based on a magnitude relation between values respectively obtained by adding the long time learning value to throttle openings respectively indicated by two effective opening area axis points of a correlation map, between which lies an actual effective opening area, and an actual throttle opening when the throttle opening learning value composed of the real-time learning value and the long time learning value is to be calculated.
