Method for exhaust gas aftertreatment of an internal combustion engine having an exhaust gas system, in which, in a position near the engine, a first SCR catalytic converter is arranged, to which is assigned a first dosing module for dosing a reducing agent necessary for the selective catalytic reduction of nitrogen oxides, and in which, in a position remote from the engine, a second SCR catalytic converter to which a second dosing module is assigned is arranged downstream of the first SCR catalytic converter, comprising the following steps: - determining or calculating at least one temperature in the exhaust gas system of the internal combustion engine, - determining the load state of the ammonia load of the SCR catalytic converters (38, 50), - dosing reducing agent by the first dosing module and/or the second dosing module as a function of the ammonia load of the SCR catalytic converters (38, 50) and the temperature in the exhaust gas system, wherein - a first dosing strategy for the reducing agent is provided in which the greatest possible conversion of nitrogen oxides into molecular nitrogen is provided by the first SCR catalytic converter, wherein, in the first dosing strategy: in a first operating state of the internal combustion engine at low engine loads, reducing agent is dosed into the exhaust gas channel exclusively by the first dosing module upstream of the first SCR catalytic converter if an ammonia target load of the first SCR catalytic converter is undershot; in a second operating state of the internal combustion engine, reducing agent is dosed both by the first dosing module and the second dosing module in such a way that both SCR catalytic converters (38, 50) reach a defined ammonia load; in a third operating state of the internal combustion engine, the ammonia load of the second SCR catalytic converter is regulated via the second dosing module, wherein - a dosing of the reducing agent is determined as a function of the efficiency of the use of reducing agent such that, - for the first SCR catalytic converter and the second SCR catalytic converter, in each case, degrees of conversion are stored in a characteristic map of the control unit of the internal combustion engine which are dependent upon a NOx mass flow in the exhaust gas, the exhaust gas temperature, the spatial velocity, the degree of aging of the catalytic converter, and the dosed amount of reducing agent, and - when the low-pressure exhaust gas recirculation valve is open, the injected amount of the reducing agent dosed via the first dosing module is reduced, compared to operation when the low-pressure exhaust gas recirculation valve is closed. - determining or calculating at least one temperature in the exhaust gas system of the internal combustion engine, - determining the load state of the ammonia load of the SCR catalytic converters (38, 50), - dosing reducing agent by the first dosing module and/or the second dosing module as a function of the ammonia load of the SCR catalytic converters (38, 50) and the temperature in the exhaust gas system, wherein - a first dosing strategy for the reducing agent is provided in which the greatest possible conversion of nitrogen oxides into molecular nitrogen is provided by the first SCR catalytic converter, wherein, in the first dosing strategy: in a first operating state of the internal combustion engine at low engine loads, reducing agent is dosed into the exhaust gas channel exclusively by the first dosing module upstream of the first SCR catalytic converter if an ammonia target load of the first SCR catalytic converter is undershot;
