Abstract
This disclosure relates to a method for controlling a system for regenerating a diesel particulate filter. The method includes monitoring an engine run time that has lapsed since a previous regeneration event. The method also includes monitoring backpressure behind the diesel particulate filter. The method further includes triggering a regeneration flag if the engine run time that lapsed since the previous regeneration event reaches a predetermined time limit and the backpressure exceeds a minimum value.
