Abstract

A method (200) for operating an exhaust-gas catalytic converter (130) with central coordination of heating measures that are intended to heat the exhaust-gas catalytic converter (130) 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.
