Abstract
A method for controlling a motor vehicle with an internal combustion engine and a catalytic converter is disclosed. The method includes: determining an oxygen storage value, which is a dimension for oxygen stored in the catalytic converter, detecting an engine load, carrying out a part evacuation of the oxygen from the catalytic converter with a fuel enrichment when the oxygen storage value exceeds a trigger evacuation threshold value and when the engine load is below a low-load threshold value.
