Abstract

Aspects of a method and system for vehicular power distribution utilizing power over Ethernet are provided. In this regard, power may be distributed via one or more Ethernet links to one or more devices of a vehicular electronics network, where the Ethernet links may also communicate multimedia and/or control information to and/or from the devices. Power may be distributed to devices of the vehicular electronics network in accordance with power over Ethernet standards. At least one component in the vehicular electronics network may operate as power supplying equipment (PSE). At least one component in the vehicular electronics network may operate as a powered device (PD). At least one component in the vehicular electronics network may operate as a powered device. An amount of power distributed to one or more of the devices may be determined based on a power classification of the one or more devices.

Claims

1. A method for vehicular electronics, the method comprising:

distributing power to one or more electronic devices in a vehicle via one or more Ethernet cables, wherein said Ethernet links are operable to communicate multimedia information and/or control information to and/or from said one or more electronic devices.

2. The method according to claim 1, wherein said one or more Ethernet cables comprise twisted pair cables terminated with modular connectors.

3. The method according to claim 1, comprising distributing said power in adherence with power over Ethernet standards.

4. The method according to claim 1, comprising distributing native vehicle power via said one or more Ethernet cables.

5. The method according to claim 1, wherein said one or more Ethernet cables carry power and data simultaneously.

6. The method according to claim 1, wherein at least one of said one or more electronic devices comprise a node operating as power supplying equipment.

7. The method according to claim 6, wherein said node is an endspan.

8. The method according to claim 6, wherein said node is a midspan.

9. The method according to claim 1, wherein at least one of said one or more electronic devices operates as a powered device.

10. The method according to claim 1, comprising distributing an amount of power to said one or more electronic devices based on a power classification of said one or more electronic devices.

11. The method according to claim 1, wherein said one or more devices comprise a plurality of Ethernet ports such that said one or more devices may be daisy-chained.

12. The method according to claim 1, wherein said one or more cables comprise one or more redundant cables operable to distribute said power to said one or more devices.

13. A system for vehicular electronics, the system comprising:

one or more circuits in a vehicular electronics network operable to distribute power to one or more devices of said vehicular electronics network via one or more Ethernet links, wherein said Ethernet links are operable to communicate multimedia information and/or control information to and/or from said one or more devices.

14. The system according to claim 13, wherein said one or more Ethernet links comprise twisted pair cables with modular connectors.

15. The system according to claim 13, wherein said one or more circuits are operable to distribute said power in adherence with power over Ethernet standards.

16. The system according to claim 13, wherein said one or more circuits are operable to distribute native vehicle power via said one or more Ethernet cables.

17. The system according to claim 13, wherein said one or more Ethernet cables carry power and data simultaneously.

18. The system according to claim 13, wherein at least one of said one or more devices comprise a node operating as power supplying equipment.

19. The system according to claim 18, wherein said node is an endspan.

20. The system according to claim 18, wherein said node is a midspan.

21. The system according to claim 13, wherein at least one of said one or more electronic operates as a powered device.

22. The system according to claim 13, wherein said one or more circuits are operable to distribute an amount of power to said one or more devices based on a power classification of said one or more devices.

23. The system according to claim 13, wherein said one or more devices comprise a plurality of Ethernet ports such that said one or more devices may be daisy-chained.

24. The system according to claim 13, wherein said one or more cables comprise one or more redundant cables operable to distribute said power to said one or more devices.
