ABSTRACT:
The invention relates to a procedure to heat up or keep warm an exhaust gas emission control assembly of a vehicle with a drive train containing one transmission. The drive train is powered by an internal combustion engine and at least one second drive unit. It is proposed that also in an operating state, which lies outside of the idle speed, a rotational speed or a torque of the internal combustion engine deviating from values for the engine rotational speed and the torque is set, which would exist during an identical driving condition without the heating-up or keeping warm of the exhaust gas emission control assembly.
