Abstract
A method and system for controlling a diesel particulate filter includes a particulate matter load determination module determining a particulate matter load in a diesel particulate filter (DPF), a desired oxygen level determination module determining a desired exhaust gas oxygen level based on the particulate matter load, an oxygen comparison module comparing the desired exhaust gas oxygen level and a measured exhaust gas oxygen level and generating a comparison signal and an electric DPF control module controlling an electrically heated catalyst in response to the comparison signal.
