Abstract: A method for regenerating an Otto particle filter of an internal combustion engine of a vehicle includes identifying a loading state of the Otto particle filter above a regeneration threshold and operating the internal combustion engine in a heating mode for the purposes of heating the Otto particle filter to a temperature threshold. The method further includes switching a first cylinder of the internal combustion engine from a fuel supply to an air supply, and continuing to operate at least one further cylinder of the internal combustion engine with the fuel supply.

Abstract: 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.
