A method for optimizing a power requirement of a motor vehicle that includes a speed control system for a drive unit and a temperature control system for a cooling circuit of the drive unit. A first power requirement of the drive unit to be expected and a second power requirement of the cooling circuit to be expected are determined based on at least one route parameter. A driving strategy corresponding to the route parameter is initially selected, and the first power requirement corresponding to the driving strategy and the second power requirement corresponding to the driving strategy are determined. Based on the determined first and second power requirements, the driving strategy is then adjusted in such a way that an overall power requirement of the motor vehicle is minimized.

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.
