Abstract

A particulate filter (PF) ash loading prediction method includes the steps of: regenerating the PF using a first soot loading prediction model or a second soot loading prediction model; determining whether the regeneration of the PF was initiated by the first soot loading prediction model or the second soot loading prediction model; incrementing a first counter associated with the first soot loading prediction model or a second counter associated with the second soot loading prediction model, dependent on the determining step; comparing a ratio of the first counter and the second counter; and establishing whether the PF requires servicing, dependent on the ratio.
