A drive train control arrangement for a motor vehicle drive train includes a main drive train, a first drive axle permanently driven by the main drive train, an auxiliary drive train and a second drive axle coupleable to the main drive train via the auxiliary drive train, which has a first clutch unit and a second clutch unit connected downstream in the power train of the first clutch unit for connecting the second drive axle to the main drive train, and a control unit, which in at least one operating mode that closes the at least one second clutch unit of the auxiliary drive train to shift into a standby operating mode when a defined operating condition is present, and with the standby operating mode activated, closes the first clutch unit of the auxiliary drive train to connect the coupleable second drive axle depending on at least one parameter.

Drive train control arrangement

In a motor vehicle drive train device with a drive engine and a drive train which has a first coupling unit in the form of a clutch arranged close to the drive engine and at least one second coupling unit arranged in the flow of force from the drive engine close to the drive wheels of the vehicle, a control unit is provided which controls the coupling units and which has an overrun operating mode wherein, at a first point, the drive engine can be disconnected from the drive train by opening the clutch and, at a second point, the coupling units close to the drive wheels can be disengaged so as to disconnect the drive train also from the drive wheels.
