A heating of a catalytic converter in the exhaust gas of an internal combustion engine is presented which can be operated in different operating modes and wherein at least one of several heating measures can be selected so that, at first, an estimate can be made for several heating measures as to whether an individual heating measure can make the desired heating effect available and that it is further estimated whether an individual heating method can be carried out in the instantaneous operating state with a view to the exhaust-gas values and the operating mode of the internal combustion engine, which is necessary for carrying out the heating measure; and that that operating mode is requested wherein the requests can best be satisfied and that at least one possible heating measure is activated in dependence upon the instantaneous mode of operation. The invention further is directed to an electronic control unit for carrying out the method.
