Abstract: To suppress variation in the activation of a catalyst for purifying exhaust gas.SOLUTION: Upon the start of an engine, when determining that the warming-up control of a catalyst is necessary, an ECU starts the warming-up control. First, the ECU executes first processing for a first set time. In the first processing, the ECU brings the engine to an idle state (S7), and fully opens a waste gate valve (S9). Upon the elapse of the first set time after the start of execution of the first processing (YES in S11), the ECU executes second processing. In the second processing, the ECU sets the rotational speed of the engine to a prescribed rotational speed (S13), and fully closes the waste gate valve (S15). Upon the elapse of a second set time after the start of execution of the second processing, the ECU finishes the second processing and finishes the warming-up control.SELECTED DRAWING: Figure 8
