Patent ID: 7246657

Claim:
An air conditioner for a vehicle having first and second air conditioning zones positioned at right and left sides of a front seat in a vehicle compartment, and third and fourth air conditioning zones positioned at right and left sides of a rear seat in the vehicle compartment, the air conditioner comprising: environmental condition determining means for determining environmental conditions of the first to fourth air conditioning zones by respectively detecting the environmental conditions or by estimating the environmental conditions from at least one of detected values; setting means for setting each of desirable temperatures of the first to fourth air conditioning zones by a passenger in the vehicle compartment; calculating means for calculating each of target blowing-out temperatures of air blown out to the first to fourth air conditioning zones in accordance with the environmental conditions determined by the environmental condition determining means and the desirable temperatures of the first to fourth air conditioning zones; and control means for respectively independently controlling temperatures of air blown out to the first to fourth air conditioning zones, to the target blowing-out temperatures, respectively, wherein the calculating means corrects an influence from the other air conditioning zones by using a selected desirable temperature in the desirable temperatures of the first to fourth air conditioning zones, while calculating the individual target blowing-out temperatures of the first to fourth air conditioning zones.
