Abstract
A particulate filter is monitored for a particulate matter load when fluidly coupled to an internal combustion engine. Monitoring of the particulate filter is achieved by determining a rate of production of particulate matter from the internal combustion engine, a rate of capture of the particulate matter within the particulate filter, a regeneration rate for the particulate filter, and an amount of particulate matter collected in the particulate filter.
