Abstract

The invention discloses a method for operating a drive device (10), in particular in a motor vehicle, comprising an internal combustion engine (12) and at least one further drive assembly (28) which is not an internal combustion engine (12), wherein an exhaust gas from the internal combustion engine (12) is treated by means of an exhaust gas treatment system (16), and wherein it is checked whether the internal combustion engine (12) is in an operating point defined as favorable for the exhaust gas treatment, and wherein then if it is found that the internal combustion engine (12) is not in an operating point defined as favorable for the exhaust gas treatment, the operating point of the internal combustion engine (12) is brought using the further drive assembly (28) into a range defined as favorable for the exhaust gas treatment.
