Abstract
When a catalyst temperature is lower than a predetermined temperature on a second or subsequent start of an engine since system activation of a vehicle, a catalyst warm-up request is output for the purpose of warming up a catalyst in a catalytic converter. An output limit Wout of a battery is not increased in response to a second or subsequent output of the catalyst warm-up request, while being increased in response to a first output of the catalyst warm-up request. Accordingly, the catalyst warm-up in response to the second or subsequent output of the catalyst warm-up request since the system activation suppresses excessive output of electric power from the battery and thereby suppresses deterioration of the battery. Catalyst warm-up is performed in response to the second or subsequent output of the catalyst warm-up request. This suppresses deterioration of emission. As a result, this configuration satisfies both (balances) suppression of deterioration of the battery and suppression of deterioration of emission.
