A method for operating an internal combustion engine includes the steps of determining an oxygen filling state of an oxygen storage of a catalytic converter by way of a first lambda signal provided by a first lambda probe and an offset value, the first lambda probe being arranged in an exhaust gas stream upstream of the catalytic converter; when a second lambda signal provided by a second lambda probe arranged in the exhaust gas stream upstream of the catalytic converter falls below a lower lambda signal threshold, setting the oxygen filling state to a first value corresponding to an empty oxygen storage and/or when the second lambda signal exceeds a upper lambda signal threshold setting the oxygen filling state to a second value corresponding to a full oxygen storage; immediately thereafter regulating the oxygen filling state during at least one regulation time period to a target filling state; and after expiration of the regulation time period adjusting the offset value by way of the second lambda signal. |
