Beschreibung
Zusammenfassung:	A method and apparatus for cleaning up a particulate filter of an internal combustion engine is provided. The internal combustion engine is operated to regenerate the particulate filter measuring. During the regeneration, a value of an engine speed is determined. A temperature of the particulate filter is controlled, if the measured value of the engine speed is smaller than or equal to a predetermined threshold value thereof. The particulate filter temperature is controlled by boosting the internal combustion engine and supplying the internal combustion engine with an amount of recirculated exhaust gases.
