摘要: A method and a device are described for controlling an exhaust gas aftertreatment system, in particular of an internal combustion engine. A special operation is intermittently carried out. The control and/or monitoring of the special operation is carried out as a function of a first quantity (O1) which characterizes the oxygen concentration in the exhaust gas upstream from the exhaust gas aftertreatment system, and a second quantity (O2) which characterizes the oxygen concentration in the exhaust gas downstream from the exhaust gas aftertreatment system.
