Abstract
The control device includes an operation state detector, an intake manifold pressure detector, an air humidity detector, an air temperature detector, an atmospheric pressure detector, and a controller that controls the engine output on the basis of detection results of the detectors. The controller generates humidity information on the air which is taken in by the internal combustion engine, from the humidity, temperature, and atmospheric pressure, calculates a dry air partial pressure by correcting the pressure detected by the intake manifold pressure detector, by using the humidity information, and controls the engine output by taking the pressure detected by the intake manifold pressure detector as a wet air pressure and selecting, according to a control element, either one of the wet air pressure and the dry air partial pressure as a pressure to be used for the engine output control.
