Method and device for the coordinated control of mechanical, electrical and thermal power flows in a motor vehicle

Abstract

A method for the coordinated control of mechanical, electrical and thermal power flows in a motor vehicle for bringing about optimum operating states of units in the motor vehicle, and a device for carrying out the method. An optimum operating state (x) for the unit system is determined in a module which receives as input variables at least the setpoint values provided by a second module after the variables determined by a third module have been combined together with additional specified variables in the second module, and the actual operating state (x) from a fourth module after the measured variables (y) resulting from the determination of the state of the units of the unit system have been combined in the fourth module; and after the optimum operating state (x) for the unit system is determined, the setpoint operating state (x) is determined in a fifth module, based on the actual operating state (x) and the optimum operating state (x), so that due to this fifth module, a smooth transition is effected between the instantaneous operating state (x) and the operating state (x) to be achieved.
