摘要：An internal combustion engine is fluidly coupled to an exhaust aftertreatmentsystem including a particulate filter. A method for operating the internal combustion

engine includes determining an expected boost pressure of an intake air compressorsystem in response to an output torque request, determining a deviation between anactual boost pressure and the expected boost pressure, determining a engine-out sootgeneration rate correction based upon the deviation between the actual boost pressureand the expected boost pressure, adjusting a steady-state engine-out soot generationrate using the engine-out soot generation rate correction, time-integrating the adjustedsteady-state engine-out soot generation rate, and commanding regeneration of theparticulate filter when the time-integrated adjusted engine-out soot generation rateexceeds a predetermined threshold.
