ABSTRACT:
A method and apparatus for ventilation of a vehicle interior which can be switched between an incoming air operating mode and a circulating air operating mode as a function of harmful substances. The incoming-air concentrations of several harmful gases are measured and are separately evaluated. In each case either an incoming air operation request or a circulating air operation request is generated. A circulating air operation adjustment command is generated if the analysis for at least one of the harmful gases results in a circulating air operation request. The incoming air operation the vehicle-interior concentration of each harmful gas is estimated continuously as a function of the pertaining measured incoming-air concentration and of an incoming air rate, and a circulating air operation adjusting command is generated if the estimated interior concentration of at least one harmful gas rises at a rate which exceeds a definable threshold value.
