Abstract
An ECU executes a program including: detecting a catalyst temperature T upon start of an engine; outputting an instruction signal to drive a power module, which is disposed in contact with an outer surface of a catalyst and is high in heat resistance, with a low efficiency upon determination that the catalyst temperature need be increased; and outputting a valve opening instruction signal to a switch valve in a cooling system in such a manner as not to allow a coolant to flow in a coolant pipeline interposed between the power module and an electric part low in heat resistance.
