Abstract: A system and method for robust automatic control of an air-conditioning system in a vehicle includes at least one sensor configured to continuously capture technical driving parameters of the vehicle. The system has a computing unit configured to determine a current air quality from the captured technical driving parameters by way of a suitable algorithm. The system has a control unit configured to control the air-conditioning system in the vehicle, wherein the control of the air-conditioning system includes activating the recirculation circuit of the air-conditioning system and/or activating the fresh-air circuit of the air-conditioning system with reference to the determined air quality.

Abstract: A method for controlling a ventilation/air-conditioning system of a vehicle and a vehicle having such a system, are provided. In a recirculated-air mode in which air in the passenger compartment is circulated and a fresh-air supply is shut off, at least one quality parameter of the recirculated air is measured at a point in the air duct system at which fresh air mixes with recirculated air to form mixed air. When the fresh-air supply is briefly opened fresh air from the environment briefly enters the air duct system, mixes with recirculated air, and at least one quality parameter of the mixed air is measured and compared with that of the recirculated air. The recirculated-air mode is maintained if the at least one quality parameter of the mixed air is worse than that of the recirculated air, and a switch to fresh air mode is made if the at least one quality parameter of the mixed air is better than that of the recirculated air.
