Abstract

A method and apparatus controls and/or regulates the evaporator temperature of an air conditioning system in a motor vehicle in cooling mode. When an outside air temperature exceeds a predetermined limit value, the evaporator temperature is controlled and/or regulated to a predetermined minimum evaporator temperature until a predetermined desired temperature in the interior of the vehicle is reached. After reaching the predetermined desired temperature in the interior of the vehicle, the evaporator temperature is increased until a predetermined interior humidity in the vehicle is reached, or the interior temperature is higher than the predetermined desired temperature for the interior of the vehicle.
