Abstract
When a starting point water temperature Twst is equal to or lower than a threshold value Twref, catalyst warm-up control is executed, and when a cooling water temperature Tw becomes higher than the threshold value Twrefor an operation time top of an engine becomes equal to or higher than a threshold value topref, the control of the engine is shifted from the catalyst warm-up control to normal control. When the starting point water temperature Twst is higher than the threshold value Twrefand is equal to or lower than a threshold value Twref, PN suppression control is executed, and when the cooling water temperature Tw of the engine becomes higher than the threshold value Twrefor the operation time top of the engine becomes equal to or higher than a threshold value topref, the control of the engine is shifted from the PN suppression control to the normal control.
