Abstract:
1. An energy supply system for an electrically operated vehicle subsystem of a motor vehicle having an engine, a driven wheel, and a battery, comprising: a generator adapted to be driven by the vehicle engine to provide electrical energy to the vehicle subsystem and for charging the vehicle battery; a control unit for setting an input power provided to the generator by the vehicle engine; and at least one interface for connecting the vehicle subsystem to the control unit and for transferring power request signals of the vehicle subsystem to the control unit, wherein the control unit is configured to set the output voltage of the generator based on a power request of the vehicle subsystem, wherein the vehicle subsystem includes a transmission for transferring torque from the engine to the driven wheel and a comparator to compare a voltage available at the transmission with a threshold value, the vehicle subsystem being operable to transmit a power request signal via the interface to the control unit based on the comparison of the voltage to the threshold value.
