The invention relates to a process for the lambda control of an internal combustion engine with exhaust catalyst, having a lambda probe mounted downstream from the exhaust catalyst as control probe, a probe by means of which a post-catalyst lambda value of an exhaust gas flow leaving the exhaust catalyst is registered. Furthermore, a lambda control mechanism is provided by means of which the post-catalyst lambda value is set to a predetermined value such that a specific, predetermined degree of oxygen charging of an oxygen reservoir of the exhaust catalyst is set, the value predetermined for the degree of charging with oxygen of the oxygen reservoir being predetermined as a function of a predetermined degree of conversion of the exhaust catalyst.
