A procedure to operate a particle filter disposed in an exhaust gas area of an internal combustion engine and a device to implement the procedure are proposed. The particle filter is regenerated if required by the particles lodged in the filter, whereby the particle filter is heated for regeneration by manipulation of the exhaust gas temperature upstream in front of the particle filter. During the regeneration of the particle filter, the exhaust gas temperature is established to a specified exhaust gas temperature set point, which is dependent upon at least one parameter of the particle filter during the regeneration. The procedural approach according to the invention allows for a quick regeneration of the particle filter without endangering the particle filter with an inadmissibly high temperature.
