METHOD FOR CONTROLLING POWER FLOWS IN A MOTOR VEHICLE

The invention relates to a method for controlling power flows in a motor vehicle for consumption-optimized supply of multiple energy systems of the motor vehicle, wherein the multiple energy systems comprise at least two of the following energy systems: a compressed air system (10), a cooling system (20), a climate system (30) and an electrical system (40) with an electrical energy storage device (42). According to the method, in driving situations of the motor vehicle in which power (1) is available at low cost, for example during coasting operation and/or driving in partial load operation with an increase in load point of the internal combustion engine, a power consumption of at least one of the energy systems (10, 20, 30, 40) is increased in order to increase the energy stored in the at least one energy system, wherein the power (1) available at low cost is distributed to the energy systems as a function of a prioritization (S6, S6a) of the energy systems.
