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.

Abstract: A method is applied to regenerate particulate matter in a particulate filter of a hybrid electric vehicle having a combination of a combustion engine and an electric motor for propelling the vehicle, the hybrid electric vehicle having an electrically heated catalyst disposed in flow communication with the particulate filter in an exhaust system of the vehicle. The method determines whether the combustion engine is or is not combusting fuel, and under a condition where the combustion engine is not combusting fuel, the catalyst is electrically heated until it has reached a temperature suitable to cause ignition of the particulate matter. The electric motor is used to facilitate rotation of the combustion engine at a rotational speed suitable to draw air into and be exhausted out of the combustion engine into the exhaust system, across the catalyst, and into the particulate filter to facilitate ignition of the particulate in the filter.

Abstract: A system includes a particulate matter (PM) filter with multiple zones, an electric heater and a control module. The electrical heater includes heater segments, which each correspond with a respective one of the zones. The electrical heater is arranged upstream from and is proximate with the PM filter. The control module selectively applies a first energy level to a first one of the zones via a first one of the heater segments to initiate regeneration in the first zone. The control module also selectively applies a second energy level that is less than the first energy level to a second one of the zones via a second one of the heater segments to initiate regeneration in the second zone.
