<P>PROBLEM TO BE SOLVED: To provide a vehicle air conditioning device that is employed to a plug-in a hybrid vehicle having a drive mode in which a drive force output from an internal combustion engine becomes larger than a drive force output from a traveling electric motor, and achieved in sufficient heating. <P>SOLUTION: In an EV drive mode in which the motor-side drive force output from the traveling electric motor becomes larger than the internal combustion engine-side drive force output from the internal combustion engine G, when increasing the number of revolutions of the internal combustion engine G, and raising a temperature of the cooling water of the internal combustion engine G as a heat source for heating in-cabin blowing air, an increase degree of the number of revolutions is made higher than that in an HV drive mode in which the combustion engine-side drive force becomes larger than the motor-side drive force. By this arrangement, even in the EV drive mode in which the temperature of the cooling water is hardly raised, the temperature of the cooling water is sufficiently raised, thus achieving the sufficient heating. <P>COPYRIGHT: (C)2012,JPO&INPIT |
