Abstract
A method for operating a particle filter of a vehicle includes creating an ash to be introduced into a filter body of the particle filter by arranging a carrier material of an ash former on an input side of an end face of the filter body, as viewed in a flow direction of an exhaust gas through the particle filter, and combusting the carrier material, where a non-combustible constituent of the ash former is arranged on the carrier material. The created ash is then introduced into the filter body of the particle filter.
