Abstract
A control system comprises a combustion control module and a regeneration control module. The combustion control module controls operation of a vehicle in a first mode during which a combustion engine is off and in a second mode during which the combustion engine is on. The regeneration control module is in communication with the combustion control module and activates an electric heater during the first mode to heat an inlet of a particulate matter (PM) filter. Exhaust gas produced by the combustion engine enters the inlet and initiates a regeneration cycle of the PM filter in the second mode.
