Abstract
Termination of regeneration of a particulate filter may be based on a variable percent threshold of stored particulate, where the percent threshold of stored particulate depends on a current soot burn rate. In one example approach, a method for controlling regeneration of a diesel particulate filter comprises: terminating regeneration based on a particulate burning rate; wherein the particulate burning rate is based on operating conditions of the diesel particulate filter; the operating conditions including an amount of stored particulate in the diesel particulate filter and a temperature of the diesel particulate filter.
