Method for Operating an Exhaust Gas System of a Motor Vehicle, and Exhaust Gas System for an Internal Combustion Engine of a Motor Vehicle

A method for operating an exhaust gas system of a motor vehicle, the method comprising:

• passing exhaust gas from an internal combustion engine through an oxidation catalytic converter and a particle filter situated downstream from the oxidation catalytic converter in a direction of flow of the exhaust gas;
• and
• regenerating the particle filter to reduce a loading of the particle filter with particles filtered from the exhaust gas,
• wherein the regeneration of the particle filter is performed as a function of an aging value characterizing an aging condition of the oxidation catalytic converter in such a way that a residual particle loading remains in the particle filter, wherein the residual particle loading corresponds to a loading value greater than a threshold value that is predefined as a function of the aging value.

An exhaust gas system for an internal combustion engine of a motor vehicle, through which exhaust gas from the internal combustion engine may flow, the system comprising:

• an oxidation catalytic converter;
• a particle filter situated downstream from the oxidation catalytic converter in a direction of flow of the exhaust gas;
• an SCR catalytic converter situated downstream from the particle filter;
• and
• a control device configured to perform a regeneration of the particle filter in order to reduce a loading of the particle filter with particles filtered from the exhaust gas, wherein the control device is configured to perform the regeneration of the particle filter as a function of at least one aging value characterizing an aging condition of the oxidation catalytic converter in such a way that a residual particle loading remains in the particle filter, the residual particle loading corresponding to a loading value which is greater than a threshold value which is predefined as a function of the aging value.
