Claim Text:
1. A method for controlling regeneration of a diesel particulate filter in construction machinery, comprising: a first active regeneration operation of actively regenerating a diesel particulate filter (DPF) according to a predetermined first active regeneration schedule when a quantity of soot inside the DPF is within a predetermined allowance section; a second active regeneration operation of actively regenerating the diesel particulate filter according to a second active regeneration schedule, which is different from the first active regeneration schedule, according to the quantity of soot when the quantity of soot is within a general section larger than that of the allowance section or a danger section larger than that of the general section; and a manual active regeneration performance inducing operation of inducing performance of a manual active regeneration when the quantity of soot exceeds the danger section, wherein the second active regeneration operation includes a second active regeneration schedule adjusting operation of performing an active regeneration until the quantity of soot is smaller than that of the danger section according to a second active regeneration schedule set to be earlier than the first active regeneration schedule when the quantity of soot is within the danger section.
