Abstract
The air conditioning controller for controlling a vehicle air conditioner provided for a vehicle equipped with a navigation system includes a solar radiation sensor disposed in a front part of the vehicle, the solar-radiation direction calculating means which computes presence or absence of solar radiation entering the vehicle and an entering direction on the basis of solar position information determined from a solar position retrieval map and road information including information of structures around the road, and the solar-radiation amount calculating means for determining the solar radiation amount on based on the calculation results of the solar-radiation direction calculating means and the detected value of the solar radiation sensor. Further, the solar-radiation amount calculating means determines the solar radiation amount by correcting the detected value of the solar radiation sensor.
