PROBLEM TO BE SOLVED: To solve the problem of an air-conditioning control device for a vehicle wherein drivability is lowered with an increase of the driving torque of a compressor 22 in acceleration of a vehicle. SOLUTION: The degree of priority of air conditioning quantitatively expressing the degree of priority of the cooling control and the degree of priority of drivability quantitatively expressing the degree of priority of drivability are computed based on a temperature difference between a target temperature and a cabin-inside temperature and a travelling state of a vehicle. In the case wherein a determination that the degree of priority of drivability is larger than the degree of priority of air conditioning is done, a lower limit value of the described predetermined quantity (a lower limit of the excess quantity) for limiting the compressor torque is computed so that the quantity contributing to except the drive of a compressor 22 in the torque generated in an engine 10 can increase by a predetermined quantity than the present quantity. Based on the lower limit value of the excess quantity, the driving control of the compressor 22 is limited so that the quantity contributing to except the drive of the compressor 22 in the torque generated in the engine 10 can increase by a predetermined quantity than the present quantity.
