Abstract

A front-seat air conditioner and a rear-seat air conditioner, which are independent from each other, are provided. An engine is automatically stopped under preset stop conditions. When the engine is automatically stopped in a case in which the number of passengers is a specified preset number (five, for example) or larger during heating, the operation of the rear-seat air conditioner is stopped (reduction of power consumption) and the operation of the front-seat air conditioner is continued (prevention of windshield glass from being fogged). Thereby, the windshield glass can be prevented from being fogged during the engine's automatic stop, reducing the power consumption of air conditioning.
