Abstract

An example system including a vehicle having a multi-zone network comprising a plurality of network zones, each one of the network zones comprising at least one zone manager; wherein the plurality of network zones are arranged according to a network topology description of a selected zone architecture; and a network management controller, including a zone implementation circuit structured to interpret a zoned architecture communication scheme; a zone manager command circuit structured to interpret a zone manager command description for each of the at least one zone managers in response to the zoned architecture communication scheme; and a zone execution circuit structured to provide the corresponding zone manager command description to each of the at least one zone managers; and wherein each of the at least one zone managers is responsive to the corresponding zone manager command description to control communications.

First claim

What is claimed is:

1 . A system, comprising:
a vehicle having a multi-zone network comprising a plurality of network zones, each one of the network zones comprising at least one zone manager; wherein the plurality of network zones are arranged according to a network topology description of a selected zone architecture, the selected zone architecture determined in response to a vehicle network risk description and a vehicle performance network impact description; and a network management controller, comprising:
a zone implementation circuit structured to interpret a zoned architecture communication scheme;
a zone manager command circuit structured to interpret a zone manager command description for each of the at least one zone managers in response to the zoned architecture communication scheme; and
a zone execution circuit structured to provide the corresponding zone manager command description to each of the at least one zone managers; and
wherein each of the at least one zone managers is responsive to the corresponding zone manager command description to control communications between end points of the corresponding network zone and end points of at least one other zone of the plurality of network zones.

2 . The system of claim 1 , wherein the selected zone architecture comprises a star arrangement, wherein one of the plurality of network zones comprises a central zone having a central zone manager.

3 . The system of claim 2 , wherein the plurality of network zones further comprises:
two forward zones, each communicatively coupled to the central zone; and one rearward zone communicatively coupled to the central zone.

4 . The system of claim 1 , wherein the selected zone architecture comprises a mesh zone arrangement.

5 . The system of claim 4 , wherein the plurality of network zones further comprises:
two forward zones; one central zone; one rearward zone; and wherein each of the plurality of network zones is communicatively coupled to all of the other network zones of the plurality of network zones.

6 . The system of claim 1 , wherein the selected zone architecture comprises a ring zone arrangement.

7 . The system of claim 6 , wherein the plurality of network zones further comprises, in order:
a central zone having a central zone manager, and communicatively coupled to a first forward zone; the first forward zone communicatively coupled to a second forward zone; the second forward zone communicatively coupled to a rearward zone; and the rearward zone communicatively coupled to the central zone.

8 . The system of claim 1 , wherein the selected zone architecture comprises a two node topology, wherein each node of the two node topology corresponds to one of the plurality of network zones.

9 . The system of claim 1 , wherein the selected zone architecture comprises a three node topology, wherein each node of the three node topology corresponds to one of the plurality of network zones.

10 . The system of claim 1 , wherein the selected zone architecture comprises a four node topology, wherein each node of the four node topology corresponds to one of the plurality of network zones.

11 . The system of claim 1 , wherein at least one zone of the plurality of zones comprises a virtual network zone.

12 . A method, comprising:
interpreting a vehicle network risk description; determining a zonal architecture value in response to the vehicle network risk description and a vehicle performance network impact description; and integrating a multi-zone network on a vehicle in response to the zonal architecture value.

13 . The method of claim 12 , wherein the vehicle network risk description comprises a hardware redundancy value.

14 . The method of claim 12 , wherein the vehicle network risk description comprises a control redundancy value.

15 . The method of claim 12 , wherein the vehicle network risk description comprises a critical flow description.

16 . The method of claim 12 , wherein the vehicle network risk description comprises a critical application description.

17 . The method of claim 12 , wherein the vehicle network risk description comprises a critical communicative connection description.

18 . The method of claim 12 , wherein the vehicle network risk description comprises a failure mode description.

19 . The method of claim 12 , wherein the vehicle performance network impact description comprises a performance estimate of the multi-zone network with respect to the vehicle network risk description.
