Classification: CPC F  Y | IPC F

Claim 9:
10. A computer-readable storage medium containing instructions that are executable by a computer of an exhaust system having at least one catalytic converter, wherein control interventions of a lambda control for controlling an exhaust gas composition of an internal combustion engine are deactivated, wherein the instructions are executable to cause the computer to
ascertain a current exhaust gas composition upstream of the at least one catalytic converter,
determine a current oxygen fill level of the at least one catalytic converter on the basis of the ascertained current exhaust gas composition,
ascertain a planned control intervention on a composition of an air-fuel mixture supplied to the internal combustion engine on the basis of the determined current oxygen fill level of the at least one catalytic converter,
ascertain a current exhaust gas composition downstream of the at least one catalytic converter,
ascertain a future exhaust gas composition downstream of the at least one catalytic converter resulting on the basis of an air-fuel mixture already supplied to the internal combustion engine, and
reactivate the lambda control and specifying a control intervention to be carried out as a function of the planned control intervention and the current exhaust gas composition downstream of the at least one catalytic converter, and/or as a function of the planned control intervention and the future exhaust gas composition.
