Abstract
A regeneration control method for regenerating a continuously regenerating diesel particulate filter device capable of regenerating a filter by efficiently removing PM while suppressing the deterioration of fuel consumption and preventing a drivability from being deteriorated, wherein the clogged-state of the filter is judged in three or more phases of the clogged-state and, when the clogged-state of the filter reaches a specified phase, a specified regenerating mode operation set in correspondence with the reached phase is performed.
