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.

Abstract: A method for operating an internal combustion engine is described in which a combustion air ratio (λ) is determined and used to determine a deviation of this combustion air ratio from an in particular default or determined set point combustion air ratio. Spontaneous ignition of the internal combustion engine are detected based on the determined deviation (Δλ) and used to control the operation of the engine.
