Abstract

See full text

A method for determining a loading state of a particle filter of a motor vehicle. The method includes detecting a first differential pressure across the particle filter, determining a second differential pressure across the particle filter, and subjecting each of the first differential pressure and the second differential pressure to a filtering process in order to determine a filtered first differential pressure and a filtered second differential pressure. The method further includes subjecting each of the first filtered differential pressure and the second filtered differential pressure to an integration process in order to determine a first integral of the filtered first differential pressure and a second integral of the filtered second differential pressure, synchronizing the first integral and the second integral with one another to provide synchronized integrals, and determining, as the loading state, a ratio which is dependent on the synchronized integrals.
