| titleOfInvention | Sensor system for controlling ventilation systems in vehicles |
| abstract | A sensor system to control the ventilation systems in vehicles in recirculation or air input mode, dependent on the concentration of pollutants in the air outside the vehicle, contains a gas sensor element (52), the electric resistance of which falls when reducing gases appear, and rises when oxidizing gases appear, and an evaluation unit (51), the output of which is connected to the controller of the ventilation unit. In order to simplify the sensor technology of such a system and in order to make evaluation less complicated, the sensor system is so organized that the increase of a gas sensor signal fed into the evaluation unit (51) for a rise in the concentration of reducing gases is the approximate quantitative equivalent of the fall of the signal fed into the evaluation unit (51) for a corresponding rise in the concentration of oxidizing gases, so that the evaluation unit (51) can measure per unit of time the rise or fall in the gas sensor signal fed in, and that the evaluation unit (51) generates a switch signal to adjust the ventilation system to recirculation mode, as soon as the measured rise or fall in the gas sensor signal per unit of time quantitatively exceeds a certain threshold limit. |
