Abstract
A control system includes a heater control module, a measured duration module, and a regeneration volume module. The heater control module selectively initiates a regeneration in a zone of a particulate filter in an exhaust system. The measured duration module measures a duration of the regeneration. The regeneration volume module determines an available volume within the particulate filter to regenerate particulate based on the measured duration of the regeneration.
