Patent ID: 7891174

Claim:
A method for managing regeneration of a diesel-particulate filter for a gas-exhaust system in an internal-combustion engine of a vehicle, comprising the steps of: varying the rate of regeneration of the diesel-particulate filter; performing a first regeneration step during which the diesel-particulate filter is regenerated at a first regeneration rate; subsequently performing at least one second regeneration step during which the diesel-particulate filter is regenerated at a second regeneration rate that is faster then the first regeneration rate; verifying whether there exist conditions for activation of the first step of regeneration of the diesel-particulate filter and where said conditions exist, activating the first step of regeneration of the diesel-particulate filter; and where said conditions do not exist, creating the conditions for activation of the first step of regeneration of the diesel-particulate filter; and wherein the conditions for activation of the first step of regeneration of the diesel particulate filter comprise: a temperature at the inlet (T IN ) to the diesel-particulate filter equal to or higher than a first threshold temperature (T IN — TH ); a temperature within the diesel-particulate filter (T F ) equal to or higher than a second threshold temperature (T F — TH ); a thermal power (P T ) supplied to the diesel-particulate filter equal to or higher than a threshold thermal power (P T — TH ).
