Abstract (en)

[origin: WO03076775A1] The invention relates to a method for the regeneration of a particulate filter (7) arranged on an exhaust line (5) of an engine (3) of a motor vehicle (1), wherein the charge of said filter (7) is evaluated by means of a model wherein P= f (Qvol, soot mass), and P= Pup- Pdown, and Qvol = K * (Qair + pfuel * Qcarb) * N * Tup / Pup, or Pup et Pdown are the pressures measured respectively upstream and downstream from said particulate filter (7). The inventive method is characterized in that Pdown is modelled and in that Pup is determined by means of the relation Pup = P+Pdown.
