Patent ID: 7302324

Claim:
A device for performing a data and energy management in a vehicle, comprising: a superordinate control unit including a superordinate interface; at least one subordinate control system including a subordinate interface; and a connecting arrangement via which the superordinate control unit may be connected to the at least one subordinate control system, wherein: the superordinate control unit and the at least one subordinate control system exchange data in accordance with the subordinate interface via the connecting arrangement to achieve a bidirectional communication, the exchanged data relating to at least one electrical user, in the case of an energy demand by the at least one subordinate control system via the connecting arrangement, purposefully at least one additional connecting arrangement is able to be deactivated and/or activated by at least one superordinate switching arrangement of the superordinate control unit, in order to fulfill the energy demand, the superordinate control unit includes at least one superordinate current recording arrangement that detects an overall current, flowing via the at least one superordinate switching arrangement, of the at least one electrical user connected to the connecting arrangement, and the at least one superordinate current recording arrangement selectively deactivates the connecting arrangement if the flowing overall current exceeds a predefined boundary value.
