Abstract

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.
