A method for regenerating a particulate filter may comprise determining a temperature, a flow rate, and a total pressure drop of an exhaust gas flowing through a particulate filter, and determining a corrected soot layer permeability. The method may further comprise calculating an estimated soot load of the particulate filter based on the total pressure drop and the corrected soot layer permeability, and causing regeneration of the particulate filter when the estimated soot load is greater than or equal to a threshold value.
