Abstract:
1. A method for a coordinated control of mechanical, electrical and thermal power flows in a motor vehicle bringing about optimum operating states of at least one unit in the motor vehicle, the method comprising: determining, in a “detection of driver intent” module, at least one driver intent variable; generating, in a generation of setpoint variables module, at least one setpoint value as a function of combining the at least one driver intent variable and an additional specified variable; determining, in a determination of actual operating state module, an actual operating state as a function of at least one measured variable, the at least one measured variable determined from the state of the at least one unit of the unit system; determining, in a determination of optimum operating state module, an optimum operating state for a unit system as a function of the at least one setpoint value and the actual operating state; and determining, in a determination of setpoint operating state module, a setpoint operating state for the unit system as a function of the actual operating state and the optimum operating state, wherein the setpoint operating state is used to generate a smooth transition between the actual operating state and the optimum operating state; wherein the determining, in the determination of optimum operating state module, the optimum operating state step includes determining a plurality of possible operating states in real time during a vehicle operation so that the unit system supplies a required mechanical power, a required electrical power, and a required thermal power, and wherein the possible operating states are selected in order to satisfy physical linkages, limits of the storage systems and capacities of the units, a generalized consumption determined for each operating state according to a computing rule:
