PROBLEM TO BE SOLVED: To improve fuel consumption by frequently driving in a lean combustion region where the fuel consumption is excellent. SOLUTION: This air-conditioning control device is provided with a lean limit torque calculation means, a minimum required torque calculation means for calculating minimum required torque required for traveling a vehicle, an air-conditioning related device driving time required torque calculation means, a remaining load device driving time required torque calculation means required for driving a load device other than an air-conditioning related device, and an air-conditioning capacity margin determination means for determining whether a predetermined margin is left in the air-conditioning capacity by the air-conditioning device. The air-conditioning control device is further provided with an adjusting means for adjusting the driving condition of the air- conditioning related device so that the air-conditioning related device driving time required torque is equal to or lower than a toque value calculated by subtracting the minimum required torque and the remaining load device driving time required torque from the lean limit torque when it is determined that the total required load torque is larger than the lean limit torque and the predetermined margin is left in the air-conditioning capacity.
