The invention concerns a method () for operating a motor vehicle () with a combustion engine (), including the determination () of a current operating state of the vehicle (), the determination () of an emission state of the vehicle () during the determined operating state, carrying out () at least one measure to reduce emissions depending on the emission state and evaluating () the at least one measure in connection with the operating state with regard to its success in reducing emissions. Furthermore, a computing unit () and a computer program product for carrying out such a method () are proposed.

Method for operating a motor vehicle with a combustion engine

A method for determining a conversion capability of one or multiple exhaust gas catalytic converters, downstream from an internal combustion engine. The method includes ascertaining a respective local temperature at multiple locations within the one or the multiple catalytic converters, ascertaining a local conversion capability for a section or a partial volume of the one or the multiple catalytic converters based on the local temperature, and ascertaining a global conversion capability of the one or the multiple catalytic converters based on the ascertained local conversion capabilities. A processing unit and a computer program product for carrying out such a method are also described.

Method, processing unit, and computer program for determining a conversion capability of an exhaust gas catalytic converter

A method () for operating an exhaust-gas catalytic converter () with central coordination of heating measures that are intended to heat the exhaust-gas catalytic converter () to a temperature level at which the reactions to be catalyzed take place with an adequate reaction rate (so-called catalytic converter window). Through the central coordination of the heating measures on the basis of defined heating strategies, in which in each case one or more of the available heating measures are combined with one another in an expedient manner, the required outlay in terms of control can be considerably reduced, and mutual interference of the heating measures can be avoided.

Method for operating an exhaust-gas catalytic converter

A method () for operating an exhaust gas system () that includes a first catalytic converter () and at least one second catalytic converter (), which are both arranged downstream from an internal combustion engine () The internal combustion engine () is controlled to generate a rich exhaust gas having a first rich gas portion, () a fill level of the second catalytic converter () is ascertained with respect to at least one lean gas component that is storable in the second catalytic converter and, if the ascertained fill level drops below () a minimum fill level, () the internal combustion engine () is controlled to generate a lean exhaust gas. The internal combustion engine () is then controlled to generate a rich exhaust gas having a second rich gas portion, and subsequently controlled () to generate the rich exhaust gas having the first rich gas portion.
