Abstract:
1. A method for controlling air conditioning of a vehicle interior as a function of incident solar radiation, comprising the steps of: detecting incident solar radiation in different solid angle ranges by a plurality of sensor elements, determining of an air conditioning capacity of at least two air conditioning ducts of individually controllable air conditioning capacity for the air conditioning of different vehicle interior regions, the air conditioning capacity of each air conditioning duct being determined, in addition to taking into account an actual interior temperature, a desired interior temperature, an outside temperature and, optionally, a vehicle speed, as a function of an output signal from a sensor element assigned to each air conditioning duct or of an averaged output signal from a sensor element assigned to each air conditioning duct, calculating a sunlight steepness according to the following formula S being the sunlight steepness, A determining a correction factor with the aid of the calculated sunlight steepness, determining a corrected air conditioning capacity by multiplication of the determined air conditioning capacity by the correction factor, and setting the corrected air conditioning capacity.
