  "textContent": "The invention relates to a method for controlling a filling level of an exhaust gas component accumulator of a catalytic converter () in the exhaust gas of an internal combustion engine (), in which an actual filling level () of the exhaust gas component accumulator is determined with a first catalytic converter model (). The method is characterized in that a lambda setpoint (λ) is formed, wherein a predetermined target fill level () is converted into a base lambda setpoint by means of a second system model () which is the reverse of the first catalytic converter model (), a deviation of the actual fill level () from the predetermined target fill level () is determined and processed to a lambda setpoint correction value by means of a fill level control unit (), a sum of the base lambda setpoint value and the lambda setpoint value correction value is formed, and said sum is used to form a correction value, with which fuel metering to at least one combustion chamber () of the internal combustion engine () is influenced.",
