Method for actuating a vehicle powertrain
A method for operating a vehicle drive train includes operating the vehicle drive train with a drive unit switched on, with the drive unit connected to an output by a transmission, and with a positive-locking shifting element open. In response to a coasting operating state request for the vehicle dr...

| description | A method for operating a vehicle drive train includes operating the vehicle drive train with a drive unit switched on, with the drive unit connected to an output by a transmission, and with a positive-locking shifting element open. In response to a coasting operating state request for the vehicle drive train and a rotational speed of a transmission output being greater than a threshold, the drive unit is switched off and power flow between the drive unit and the output is interrupted by opening at least one of a plurality of frictional-locking shifting elements. The method also includes closing the positive-locking shifting element during the coasting operating state and no later than a leave coasting operating state request. |
