Abstract
A method for regenerating a particle filter during the operation of an internal combustion engine, having the following steps: detecting at least one loading parameter which is characteristic of a present loading of the particle filter, wherein an active regeneration measure can be carried out recurrently in a manner dependent on the loading parameter; determining a time window for a regeneration of the particle filter; and determining a prediction for an operating state of the internal combustion engine expected within the time window, wherein the active regeneration measure at a time indicated for it by the loading parameter is skipped if the prediction predicts that, within the time window, an operating state of the internal combustion engine will arise in which a regeneration of the particle filter takes place without an active regeneration measure.

14. A method for regenerating a particle filter during operation of an internal combustion engine, comprising the steps of:
-
recording at least one loading parameter that is characteristic of a current loading of the particle filter, wherein an active regeneration measure can be performed recurrently depending on the loading parameter; determining a time window for a regeneration of the particle filter; and determining a prediction for an operating state of the internal combustion engine that is to be expected within the time window, wherein the active regeneration measure is skipped at a point in time indicated by the loading parameter if the prediction predicts an operating state of the internal combustion engine within the time window in which a regeneration of the particle filter will take place without the active regeneration measure. - View Dependent Claims (23, 24, 25, 26, 27)
