Abstract
A method for operating a drive train of a motor vehicle with an internal combustion engine, automatic transmission and at least one drive axle, is disclosed wherein in order to save fuel during the driving mode when the accelerator pedal is not activated a clutch device which is associated with the automatic transmission is opened and subsequently the internal combustion engine is shut down. When the accelerator pedal is activated again the internal combustion engine is started and in the automatic transmission the highest possible gear speed for the reconnection is firstly selected and so that the revving up time of the engine rotational speed is as short as possible, with the result that the necessary drive torque which is generated by the internal combustion engine can be made available at the drive axle as quickly as possible.
