Abstract

An internal combustion engine makes available exhaust gas which can be treated by means of a catalytic converter and a particle filter. A method for determining the particle load of the particle filter comprises steps of determining the storage capacity of the catalytic converter for oxygen and determining the particle load of the particle filter on the basis of the determined storage capacity in the controller.
