Abstract
An internal combustion engine apparatus provided with an internal combustion engine in which ignition timing can be adjusted and which has attached thereto an exhaust gas recirculation device that recirculates exhaust gas to an intake side, a control method for the internal combustion engine apparatus, and a hybrid vehicle are provided. When it is not a recirculation ratio variation time, a target ignition timing is set by correcting a base ignition timing that has been established as a base value of an ignition timing of the internal combustion engine by a first correction amount, and when it is the recirculation ratio variation time, the target ignition timing is set by correcting the base ignition timing by a second correction amount that delays an ignition timing more than a provisional correction amount obtained by correcting the first correction amount, and the internal combustion engine is controlled so that the internal combustion engine is operated due to the ignition at the target ignition timing that has been set.
