  • Method for operating a particulate filter in an exhaust aftertreatment system of a combustion engine
    Patent number: 11346268
    Abstract: A method for the operation of a particulate filter in an exhaust aftertreatment system of a combustion engine (200) with the following steps: set up (111, 116) a pressure difference model, which models a measured pressure difference (?p) which drops across the particulate filter (210) as a function (220) of a volume flow ({dot over (V)}) through the particulate filter (210) with an offset value (a0, C); measure (120) multiple measurement values (245) for the pressure difference (?p) at different volume flows ({dot over (V)}) and solve (130) the pressure difference model as a function of the pressure difference (?p), whereby the offset value (a0, C) is also determined.
