Method for operating an exhaust gas aftertreatment, device for controlling an exhaust gas after treatment, exhaust gas aftertreatment and internal combustion engine having exhaust gas after treatment


A method and a device for operating an exhaust gas aftertreatment, wherein a diesel particulate filter is regenerated during the operation, in particular passively regenerated, wherein a corrected differential pressure is calculated from a current differential pressure across the diesel particulate filter at a current exhaust gas volumetric flow rate and with a current correction factor. The current correction factor is determined by determining a lower differential pressure in a predetermined time interval at a defined exhaust gas volumetric flow rate, in particular in a specified exhaust gas volumetric flow rate interval around the defined exhaust gas volumetric flow rate, and comparing the lower differential pressure with a specified current reference value and, depending thereon, calculating a new correction factor or retaining the previous correction factor as the current correction factor..
