摘要：
A method of regenerating a particulate filter that includes an electric heater is provided. The method includes determining a location of particulate matter that remains within at least one region of the particulate filter based on a regeneration event being extinguished; and selectively controlling current to a zone of a plurality of zones of the electric heater to initiate a restrike of the regeneration event based on the location of particulate matter.
