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.

Method for controlling and/or regulating the evaporator temperature of an air conditioning system in a motor vehicle

A method for determining the desired ventilation air temperature of an automatic heating and air-conditioning system of a vehicle having an opening top is described. The open or closed state of the top of the vehicle is detected, and the heating and air-conditioning system is controlled and/or regulated in a number of different ways as a function of the state of the top. In the open state of the top, the desired ventilation air temperature is determined as a function of the speed of the vehicle. Also, in the open state of the top the desired ventilation air temperature is determined in such a manner that the top-closed desired ventilation air temperature is increased by a speed-dependent offset value.
