Method for regenerating a particle filter (4) in the exhaust path (3) of a combustion engine (1) is commenced when a signal, e.g. proportional to the pressure drop across the filter, indicates that regeneration is necessary. Once begun, the regeneration process is regulated based on a mass flow signal that is proportional to the mass flow passing through the filter. The exhaust gas temperature is measured upstream of the filter and the mass flow is adjusted by a control loop so that a specified exhaust gas temperature is obtained. An independent claim is made for a motor vehicle exhaust gas system with a control device that controls the regeneration of a particle filter.
