Patent ID: 8312712

Claim:
A control system comprising: a regeneration control module that selectively determines that a regeneration cycle of a particulate matter (PM) filter is needed based on a load of the PM filter; a stopping frequency module that determines a stopping frequency of a vehicle based on a number of vehicle stops over a predetermined period; and a combustion control module that: before the regeneration cycle of the PM filter, provides fuel to an oxidation catalyst (OC) located upstream of the PM filter in response to a determination that the stopping frequency is greater than a predetermined frequency; and before the regeneration cycle of the PM filter, selectively shuts down an engine, wherein, while the engine is shut down before the regeneration cycle, the regeneration control module activates an electric heater to heat an inlet of the PM filter, wherein the combustion control module selectively starts the engine before the regeneration cycle, and wherein exhaust gas produced by the engine enters the inlet of the PM filter and initiates the regeneration cycle of the PM filter.
