- the invention relates to a method and a device for controlling an internal combustion engine.
- the particle filter reaches a certain load and regeneration of the filter cannot be guaranteed due to the engine operating state, it is provided that the exhaust gas temperature is increased to the extent that the particles burn off quickly. In this case, the oxidation releases so much heat that the particle filter and the exhaust gas continue to heat up. This further accelerates the oxidation, the heating of the filter becomes even greater and may lead to damage to the filter.
- Supercritical heating of the filter can also occur if the operating mode of the engine is changed during the regeneration.
- a sudden transition to overrun mode or a transition to idle mode deprives the particulate filter of the necessary cooling due to the high exhaust gas volume flow or increase the rate of combustion by means of an increased supply of oxygen in the exhaust gas flow.

- the parameter characterizes a reaction temperature and / or a temperature change caused by the reaction in the Exhaust aftertreatment system is effected. That is, as a parameter, a temperature parameter is used which characterizes the final temperature that can be achieved in a possible reaction and / or the temperature increase achieved due to the reaction. This parameter is determined on the basis of the operating parameters of the internal combustion engine and / or the exhaust gas aftertreatment system. Therefore, no additional sensors are necessary.
- the essential variables from which the characteristic variable is determined are variables which characterize a loading state of the exhaust gas aftertreatment system, an exhaust gas temperature, an air quantity and / or a combustion rate. These sizes have the greatest influence on the reaction and / or the temperature reached in the exhaust gas aftertreatment system.
- the size which characterizes the rate of degradation, can be specified starting from sizes that characterize an oxygen content in the exhaust gas and / or the exhaust gas temperature. These variables are present in the control device and / or can be determined from other variables without great effort.

- the different states are recognized by comparison with a threshold value and the regeneration is initiated depending on the detected loading state.
- Exhaust gas recirculation is provided to reduce nitrogen oxides from internal combustion engines.
- the proportion of recirculated exhaust gases or the amount of air that is fed to the internal combustion engine must be set precisely, since the particle emissions increase when the exhaust gas recirculation rate is too high and, on the other hand, the NO x emissions increase when the exhaust gas recirculation rate is too low.
