ABSTRACT:
When the vehicle stops, a target blowout temperature, a temperature after evaporator, and a predetermined temperature which has been preset are compared with each other. Accordingly, when it is judged that cooling capacity is maintained, a "start engine" demand is not outputted. When it is judged that cooling capacity is not obtained, a "start engine" demand is outputted. After a "start engine" demand has been outputted, even when cooling capacity is maintained, an engine is not stopped. As a result, fuel wastage and annoyance causing to passengers by the engine that keeps on starting up when the vehicle stops can be prevented.
