Abstract

A device and method for controlling air conduction in a vehicle includes an air conduction element. The air conduction element is controlled as a function of the moisture in the vehicle interior, intermediate positions of the air conduction element being possible between a maximum proportion of circulating air and a maximum proportion of fresh air. In this way, the proportion of fresh air is increased only gradually when there is a high pollution impact if the interior moisture does not exceed a maximum moisture value .PHI..sub.max. Control of the moisture in the vehicle interior increases the comfort of the vehicle occupants. A circulating-air dryer makes it possible, in principle, to continue in circulating-air operation for an unlimited period.
