Abstract
A method for operating a vehicle drivetrain () having a drive machine (), an output () and a gearbox () with the gearbox () arranged in power flow between the drive machine () and the output () includes opening, in the presence of a demand for activation of a sailing operating function of the vehicle drivetrain () and a simultaneously activated engine start-stop function, a positively engaging shift element (F) while the drive machine () is left both decoupled from the output () and shut down.
