Abstract
A system and method of reducing particulate matter accumulation in a diesel particulate filter of an exhaust system of a vehicle comprises operating the vehicle including an engine connected to the exhaust system in a drive mode. At least one parameter indicative of particulate matter accumulation in the diesel particulate filter is monitored and evaluated against a predetermined particulate matter accumulation limit. Control logic determines at least one operating parameter of the vehicle and adjusts the transmission assembly from a first transmission position to at least one second transmission position to increase engine speed and generate higher exhaust gas flow when the particulate matter accumulation is greater than the predetermined particulate matter accumulation to regenerate the diesel particulate filter.
