Claim 0:
1. A method of manufacturing of a vehicle network of a vehicle, the method comprising the steps of:
a. Providing
i. a plurality of vehicle network subscribers in at least two topology levels to be spatially or functionally distinguished,
ii. an energy supply device, and
iii. at least one control device;
b. Providing an interface module configured for the vehicle network, wherein the interface module comprises:
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 device of the vehicle,
iii. a number of load interfaces, each having a vehicle network subscriber of the plurality of vehicle network subscribers and wherein at least one load interface is associated with the number of load interfaces,
iv. at least one matrix coupler, the supply interface and the communication interface each having each load interface of the number of load interfaces and thus represent an interface between the at least two topology levels to be distinguished, and wherein the matrix coupler is configured to couple the number of load interfaces to each other,
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 the number of load interfaces at an end of a line,
wherein one edge of the graph represents 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
wherein one node of each graph is located on the matrix coupler,

v. wherein the interface module is set up to carry out an electrical protection of the number of load interfaces to the vehicle network subscribers,
c. supplying a first wiring harness segment comprising at least one first communication line segment, and a first energy supply line segment, wherein a first end of the first communication line segment and the first power supply line segment are bundled in a first interface at a first end of the at least one wiring harness segment;
d. coupling a second end of the first line set segment opposite the first end to a first load interface of the number of load interfaces; and
e. repeating the steps of feeding and coupling for each vehicle network subscriber of the plurality of vehicle network subscribers in order to produce an automatically producible vehicle network system with an unbundling within the matrix coupler.
