PROBLEM TO BE SOLVED: To operate an air conditioner mounted on a vehicle to the maximum without generating engine stall in deceleration of an engine. SOLUTION: When decelerationΔNe of a rotation speed Ne of the engine is predetermined deceleration ND or higher in deceleration of the engine and a presumed rotation speed Nea of the engine after a predetermined time T operated based on the decelerationΔNe becomes a predetermined rotation speed N or lower, an air conditioner cut flag is turned ON to cut operation of the air conditioner. Thereby, engine stall can be prevented by cutting operation of the air conditioner only in rapid deceleration in which the engine stall is possibly generated. COPYRIGHT: (C)2007,JPO&INPIT
