Actuation of a blower 21 in an air conditioning device 18 is prohibited in a period from initiation of starting of an engine 1 to completion of warm-up of catalyst. This prevents air from flowing in an air duct 22 through the actuation of the blower 21 and being subjected to heat exchange with coolant at a heater core 24 on a circulation path 6. As a result, after the heat generated by the engine 1 is supplied to the coolant, the heat is prevented from being provided to the interior of a passenger compartment 25. This rapidly increases the temperature of the engine 1 and the temperature of the coolant, thus raising the exhaust temperature of the engine 1. The heat is thus efficiently transmitted to a catalyst by means of exhaust gas. In other words, the heat produced by the engine 1 is distributed preferentially to the catalyst, which is a component of a vehicle aside from the passenger compartment 25 that must be heated when at a low temperature, by means of the exhaust gas.
