Claim:
1. A method for optimizing an overall power requirement of a motor vehicle, which includes a speed control system for a drive unit and a temperature control system for a cooling circuit of the drive unit, wherein the overall power requirement to be optimized includes a first power requirement of the drive unit and a second power requirement of the cooling circuit, the method comprising: selecting a driving strategy corresponding to a route parameter such that an optimum first power requirement of the drive unit corresponding to the driving strategy is determined; determining the second power requirement of the cooling circuit corresponding to the driving strategy; feeding back the determined second power requirement of the cooling circuit to the speed control system for the drive unit by the temperature control system; determining whether or not the driving strategy should be changed by the speed control system of the drive unit in order to adjust the optimum first power requirement of the drive unit based on the fed-back determined second power requirement of the cooling circuit such that the overall power requirement of the motor vehicle is minimized; and controlling actuators to implement the driving strategy in the motor vehicle.
