摘要：
A method and a device are provided for controlling an exhaust gas aftertreatment system, for example, an exhaust gas aftertreatment system of an internal combustion engine. A first quantity characterizing the amount of substances supplied to the exhaust gas aftertreatment system, based on first characteristic operating quantities, is determined in a first operating state. A second quantity characterizing the amount of substances removed from the exhaust gas aftertreatment system, based on second characteristic operating quantities, is determined in a second operating state. The first quantity and the second quantity are then compared for error detection.
