Optimization of active regeneration triggers based on ambient and vehicle operating conditions

摘要

A method of controlling the regeneration of a particulate filter includes defining a regeneration trigger limit for at least one operating parameter of the vehicle, modifying the regeneration trigger limit based upon a sensed ambient operating condition and a sensed vehicle operating condition to define a modified regeneration trigger limit, and regenerating the particulate filter when the modified regeneration trigger limit for the operating parameter is reached.
