Abstract
A control system includes a heater control module and a particulate matter (PM) load module. The heater control module selectively activates an electric heater to initiate regeneration in a zone of a particulate filter and deactivates the electric heater after the regeneration is initiated. The regeneration continues along a length of the particulate filter after the electric heater is deactivated. The PM load module determines a PM load based on an outlet temperature of the particulate filter after the regeneration is initiated.
