Abstract

Claims (16)

1 . A control device of a functional zone of a motor vehicle, comprising:

a uniform communication interface configured to provide a uniform communication link to a functional unit of a plurality of functional units in the functional zone, wherein the control device controls the functional unit via control commands transmitted by the uniform communication link to the functional unit using a communication standard; and

at least one eFuse actuation system configured to couple the control commands into the communication link via a modulation method.

2 . The control device of claim 1 , wherein the communication standard is selected from a group comprising at least LIN, CAN, Ethernet and/or CAN-FD.

3 . The control device of claim 1 , wherein the coupling-in is carried out galvanically, inductively, capacitively, by wave coupling, by beam coupling and/or directly by actuation of an eFuse.

4 . The control device of claim 1 , wherein the eFuse actuation system is designed as a software unit and/or as an electronic circuit.

5 . The control device of claim 1 , wherein the communication link is designed as a two-wire cable or a three-wire cable.

6 . The control device of claim 1 , wherein the control device has a storage unit for storing an assignment table and, in the assignment table, the control commands which can be transmitted are assigned to the corresponding functional units.

7 . A motor vehicle, comprising:

the control device of claim 1 .

8 . A method for transmitting control commands to at least one functional unit of a plurality of functional units in a functional zone of a motor vehicle, wherein the method comprises:

establishing a uniform communication link to a functional unit of the plurality of functional units in the functional zone;

coupling control commands for controlling the functional unit into the communication link by an eFuse actuation system via a modulation method; and

transmitting the control commands to the functional unit via the uniform communication link using a communication standard.

9 . A computer program comprising instructions that, when executed by a computer, cause the computer to execute the method of claim 8 .

10 . A non-transitory computer-readable medium comprising instructions that, when executed by a computer, cause the computer to execute the method of claim 8 .
