Abstract

The previously presented teaching of the invention describes a method for the evaluation of sensor signals with the purpose of producing plausible and physiologically satisfying switching impulses for interrupting or for opening the air supply in ventilation systems, particularly for the ventilation of passenger cabins in motor vehicles, depending on the pollutant content of the ambient air established by one or more sensors.
