Field: Transport (Mechanical engineering)
Classification: CPC B | IPC B

Claim 14:
15. A vehicle network system for a vehicle, comprising:
a. a plurality of vehicle network subscribers in at least two topology levels to be distinguished spatially or functionally,
b. an energy supply device,
c. at least one control unit,
d. at least one interface module for the vehicle network, comprising:
i. a supply interface for coupling to a positive pole of the energy supply device of the vehicle,
ii. a communication interface for at least one of receiving and transmitting information from a coupled or connectable control unit of the vehicle,
iii. a number of load interfaces, each having a vehicle network subscriber of the plurality of vehicle network subscribers, wherein at least one load interface is associated with the number of load interfaces,
iv. at least one matrix coupler is configured to couple the supply interface and the communication interface respectively to each load interface of the number of load interfaces and thus represent an interface between the at least two topology levels to be distinguished,
wherein the matrix coupler is set up to represent an unbundling task for linking the vehicle network subscribers,
wherein nodes of a graph representing line-connector relationships of the matrix coupler each denote a load interface of the number of load interfaces at the end of a line,
wherein an edge of the graph denotes a connection relationship of at least one line between a first load interface and a second load interface,
wherein the graph comprises at least two partite graphs with at least two partition, and
where one node of each graph is located on the matrix coupler, and

v. wherein the interface module is designed to carry out an electrical protection of the number of load interfaces to the vehicle network subscribers, and
e. a wiring harness segment for each vehicle network subscriber of the plurality of vehicle network subscribers, having at least a first communication line segment, and a first energy supply line segment per wiring harness segment, wherein a first end of the first communication line segment and the first energy supply line segment are bundled at a first end of the at least one wiring harness segment in a first interface.
