In a method and device for controlling an exhaust gas post-treatment for an internal combustion engine with at least one cylinder (Z1-Z4) and one combustion chamber (26) and one exhaust gas tract (14) in which is disposed an SCR catalyst (34), a humidity parameter (HDT EXH) of an exhaust gas in the exhaust gas tract (14) is determined upstream of the SCR catalyst (34) of the internal combustion machine. A control signal for an actuator for introducing ammonia into the exhaust gas is determined as a function of the humidity parameter (HDT_EXH) of the exhaust gas, and the actuator is adjusted accordingly.
