Abstract
A particulate filter device monitoring system for an engine includes a regeneration mode trigger module configured to set a regeneration request based on soot accumulation in the particulate filter device, a regeneration control module configured to control regeneration of the particulate filter device, and a soot out model module including a soot out model configured to calculate changes in soot out rate during prolonged engine idling periods.
