In a vehicle air conditioner, when a passenger set temperature of a vehicle compartment is changed through an operation portion by a passenger, a storage portion updates a value of a control set temperature corresponding to a predetermined point of a detection area at a time of the changing operation to a value of the changed passenger set temperature, and stores therein the value of the updated temperature. Furthermore, when the detection point is not any one of the predetermined points, a control portion interpolates and calculates a control set temperature corresponding to the detection point from the control set temperature stored in the predetermined point of the detection area and the control set temperature stored in the predetermined point of a surrounding area around the detection area, and then controls the air-conditioning state in the vehicle compartment based on the interpolated and calculated control set temperature.

The air conditioner according to claim 1, wherein the partitioning means stores the controlling set temperature interpolated and calculated by the controlling means on the map, and the controlling means controls the air-conditioning state in the vehicle compartment based on the control set temperature corresponding to the detection point on the map stored in the partitioning means when controlling the air-conditioning state in the compartment. 4. The air conditioner according to claim 1, wherein the plurality of environmental conditions are two environmental conditions. 5. The air conditioner according to claim 4, wherein the two environmental conditions are an outside air temperature which is a temperature of air outside the vehicle compartment, and an amount of solar radiation received in the vehicle compartment. 6. The air conditioner according to claim 1, wherein the predetermined point is a center point obtained by combination of respective center values of the plurality of environmental conditions in the area. 7. The air conditioner according to claim 1, wherein the controlling means performs interpolation and calculation based on fuzzy control theory. 8. The air conditioner according to claim 1, further comprising means for identifying a passenger riding in the vehicle compartment from pre-registered persons who are going to ride therein, wherein the partitioning means includes the maps corresponding to the respective persons who are going to ride, and the controlling means controls the air-conditioning state in the vehicle compartment using the control set temperature of the map corresponding to the passenger identified by the identifying means. 9. The air conditioner according to claim 1, further comprising means for receiving input of temperature information output from the controlling means and for displaying a temperature, wherein the controlling means outputs the control set temperature stored in the predetermined point of the detection area as the temperature information to the receiving means. 10. The air conditioner according to claim 9, wherein the controlling means outputs the value of the control set temperature stored in the predetermined point of the detection area as the temperature information to the receiving means in units of resolution previously specified. 11. The air conditioner according to claim 1, further comprising means for receiving input of temperature information output from the controlling means and for displaying temperature, wherein the controlling means outputs the control set temperature corresponding to the detection point as the temperature information to the receiving means. 12. The air conditioner according to claim 11, wherein the controlling means outputs a value of the control set temperature corresponding to the detection point as the temperature information to the receiving means in units of resolution previously specified. 13. The air conditioner according to claim 1, wherein when the detection point is not any one of the predetermined points, the controlling means interpolates and calculates a control set temperature corresponding to the detection point from the control set temperature stored in the predetermined point of the detection area and the control set temperatures stored in the predetermined points of three surrounding areas, the detection point is surrounded by the predetermined point of the detection area and the predetermined points of the three surrounding areas, the controlling means controls the air-conditioning state in the vehicle compartment based on the interpolated and calculated control set temperature; and one of the plurality of areas is disposed between the detection area and each of the three surrounding areas. 14. The air conditioner according to claim 13, wherein the predetermined point is a center point obtained by combination of respective center values of the plurality of environmental conditions in the area. 15. The air conditioner according to claim 13, wherein one of the plurality of areas is disposed between a first one and a second one of the three surrounding areas. 16. The air conditioner according to claim 15 wherein one of the plurality of areas is disposed between the second one and a third one of the three surrounding areas.
