Abstract
When it is determined that control of warm-up of a catalyst is necessary at the time of start of an engine, an ECU starts warm-up control. Initially, the ECU performs first processing for a first set time period. In the first processing, the ECU sets the engine to an idle state and fully opens a waste gate valve. When the first set time period has elapsed since the first processing was started, the ECU performs second processing. In the second processing, the ECU sets the engine to a prescribed rotation speed and fully closes the waste gate valve. When a second set time period has elapsed since the second processing was started, the ECU quits the second processing and quits warm-up control.
