A method for controlling air conditioning devices in a transportation vehicle wherein, upon the recording of an operator's air conditioning need and a conversion of the need into an air conditioning function for an air conditioning device, the implementability of the air conditioning need is compared with an influencing variable measured by a sensor. In response to the air conditioning need being recognized as implementable, information asserting this fact is issued to the operator. An apparatus for performing the method.

Method and apparatus for controlling air conditioning devices in a transportation vehicle

An air-conditioning system for a motor vehicle includes a coolant circuit, through which it is possible to pump coolant with the aid of a compressor, the air-conditioning system having a torque-determining unit for determining a drive torque required for operating the compressor as a function of a temperature of air, which has flowed past an evaporator integrated into the coolant circuit for evaporating coolant, a pressure of the coolant prevailing in the coolant circuit in front of the compressor relative to a flow direction of the coolant or an actuating signal for setting a settable compressor stroke of the compressor.
