1. A system for automatic control of an air-conditioning system in a vehicle, comprising:
at least one sensor configured to continuously capture technical driving parameters of the vehicle;
a computer configured to determine a current air quality from the captured technical driving parameters without using an air quality sensor; and
an electronic controller configured to control the air-conditioning system in the vehicle, wherein
the control comprises activating a recirculation circuit and/or activating a fresh-air circuit of the air-conditioning system with reference to the determined current air quality,
the at least one sensor comprises a position determination sensor,
the captured technical driving parameters comprise a current geographical position of the vehicle and a current number of real-time satellite connections detected using the position determination sensor, and
the current air quality is determined by the computer to be better with a greater number of current real-time satellite connections than with a fewer number of real-time satellite connections.
