| 摘要 |
The invention relates to a method for processing measured values from a first nitrogen oxide sensor (7), arranged upstream of a nitrogen oxide reduction catalyst (4) in the exhaust gas section (9) of a motor vehicle, and measured values from a second nitrogen oxide sensor (8), arranged downstream of the nitrogen oxide reduction catalyst (4) in the exhaust gas section (9) of the motor vehicle, in which measured values from the first and second nitrogen oxide sensors (7; 8) are recorded and compared with one another at least approximately at the same time. According to the invention, a sensitivity of the first nitrogen oxide sensor (7) and/or of the second nitrogen oxide sensor (8) is changed on the basis of the result of the comparison. |
