| description | A method for monitoring particulate filter disposed in an exhaust aftertreatment system of an internal combustion engine includes determining, via a differential pressure sensor, a pressure differential across the particulate filter, and determining an initial parameter associated with soot loading on the particulate filter based upon the pressure differential. A first adjustment to the soot loading is determined based upon a passive regeneration effect, a second adjustment to the soot loading is determined based upon an off-engine temperature effect, and a third adjustment to the soot loading is determined based upon occurrence of an interrupted regeneration event. A final parameter associated with soot loading on the particulate filter is determined based upon the initial parameter and the first, second and third adjustments. |
