Method for Actuating a Vehicle Drivetrain

A method actuates a vehicle drivetrain of a vehicle having a drive unit, in particular an electric motor, wherein the drivetrain has at least one first partial drivetrain which is assigned to a first output unit which transmits a torque between the drive unit and the first output unit, and has at le...

Beschreibung
Zusammenfassung:	A method actuates a vehicle drivetrain of a vehicle having a drive unit, in particular an electric motor, wherein the drivetrain has at least one first partial drivetrain which is assigned to a first output unit which transmits a torque between the drive unit and the first output unit, and has at least one second partial drive train which is assigned to a second output unit which transmits a torque between the drive unit and the second output unit. When a positive torque is transmitted, a load is applied to the drivetrain in a first direction, and when a negative torque is transmitted, a load is applied to the drivetrain in a second direction opposed to the first direction. At least one pre-load device is provided which, when a predetermined positive torque limiting value is reached or when a predetermined negative torque limiting value is reached, pre-loads the first partial drivetrain in the first direction of the positive torque and pre-loads the second partial drivetrain in the second direction of the negative torque.
