A method for regenerating a particulate filter configured to treat engine exhaust gas in a vehicle equipped with an on-board navigation and an extra-vehicle communications system includes monitoring present operation of the vehicle, projecting vehicle operating conditions based upon information from the on-board navigation and the extra-vehicle communications system, monitoring a storage capacity of the particulate filter, executing a control scheme to regenerate the particulate filter when the storage capacity of the particulate filter exceeds an upper threshold, executing the control scheme to regenerate the particulate filter when the storage capacity of the particulate filter is less than the upper threshold and in response to an operator request to regenerate the particulate filter, and executing the engine control scheme to regenerate the particulate filter when the storage capacity of the particulate filter is less than the upper threshold and the projected vehicle operating conditions indicate an opportunity to regenerate the particulate filter.
