Abstract

Vehicle internetworks provide for communications among diverse electronic devices within a vehicle, and for communications among these devices and networks external to the vehicle. The vehicle internetwork comprises specific devices, software, and protocols, and provides for security for essential vehicle functions and data communications, ease of integration of new devices and services to the vehicle internetwork, and ease of addition of services linking the vehicle to external networks such as the Internet.

Claims

1. A device comprising:

a first interface;

a second interface; and

a computing device configured to access a first vehicle bus in a vehicle via the first interface and access a second vehicle bus in the vehicle via the second interface, and wherein the computing device is further configured to;

manage transmission of messages between the first vehicle bus and the second vehicle bus, and

authorize access to the first vehicle bus and the second vehicle bus.

2. The device of claim 1, wherein the first vehicle bus comprises an original equipment manufacturer bus, an automotive multimedia interface consortium bus, an external network, a legacy automotive bus, or a local development network, and wherein the second vehicle bus comprises another of the original equipment manufacturer bus, the automotive multimedia interface consortium bus, the external network, the legacy automotive bus, or the local development network.

3. The device of claim 1, wherein the computing device is further configured to block unauthorized messages being transferred between the first vehicle bus and the second vehicle bus.

4. The device of claim 1, wherein the computing device is further configured to selectively shut down a network element.

5. The device of claim 1, wherein the computing device comprises a real-time interface processor configured to perform real-time processes and an application processor configured to perform high-level processing functions.

6. The device of claim 1, wherein the computing device is configured to route packets to appropriate destinations and issue commands for control of networks for which the computing device is serving as master.

7. A device comprising:

a first interface configured to use a first network protocol;

a second interface configured to use a second network protocol, wherein the first network protocol differs from the second network protocol; and

a computing device configured to;

control asynchronous operation of the first interface and the second interface based on information regarding slot availability on the first interface and the second interface, and

enforce a policy related to authorizing access to a first vehicle bus and a second vehicle bus.

8. The device of claim 7, wherein the policy comprises a policy for support of a service, the device further comprising a memory cache configured to store the policy.

9. The device of claim 8, wherein the service comprises at least one of security and authentication of devices or prioritization of resource requests.

10. The device of claim 7, further comprising a memory cache configured to store short-term queuing information that includes an interval between slot availability on opposite sides of the first or second interface.

11. The device of claim 7, wherein the computing device is configured to translate network protocols for both wired and wireless networks.

12. The device of claim 7, wherein the computing device comprises a real-time interface processor configured to perform real-time processes.

13. The device of claim 7, wherein the computing device is further configured to:

cause the first interface to transport data at a first data rate; and

cause the second interface to transport data at a second data rate.

14. A method comprising:

accessing, by a computing device, a first vehicle bus in a vehicle via a first interface;

accessing, by the computing device, a second vehicle bus in the vehicle via the second interface;

managing, by the computing device, transmission of messages between the first vehicle bus and the second vehicle bus; and

authorizing, by the computing device, access to the first vehicle bus and the second vehicle bus.

15. The method of claim 14, wherein the first vehicle bus comprises an original equipment manufacturer bus, an automotive multimedia interface consortium bus, an external network, a legacy automotive bus, or a local development network, and wherein the second vehicle bus comprises another of the original equipment manufacturer bus, the automotive multimedia interface consortium bus, the external network, the legacy automotive bus, or the local development network.

16. The method of claim 14, further comprising blocking unauthorized messages being transferred between the first vehicle bus and the second vehicle bus.

17. The method of claim 14, further comprising shutting down, by the computing device, a misbehaving network element.

18. The method of claim 14, wherein the computing device comprises a real-time interface processor configured to perform real-time processes and an application processor configured to perform high-level processing functions.

19. The method of claim 14, further comprising issuing commands for control of networks for which the computing device is serving as master.

20. A method comprising:

causing, by a computing device, a first interface to transport data at a first data rate, wherein the first interface uses a first network protocol;

causing, by the computing device, a second interface to transport data at a second data rate, wherein the second interface uses a second network protocol, and wherein the first network protocol differs from the second network protocol;

controlling, by the computing device, asynchronous operation of the first interface and the second interface based on information regarding slot availability on the first interface and the second interface; and

enforcing, by the computing device, a policy related to authorizing access to a first vehicle bus and a second vehicle bus.

21. The method of claim 20, further comprising storing on a memory cache the policy, wherein the policy comprises a policy for support of security and authentication service or for support of a service for prioritization of resource requests.

22. The method of claim 20, wherein the first network protocol is associated with a legacy device, the method further comprising translating the first network protocol such that the computing device may transfer information from the first network protocol to a network element associated with the second network protocol.

23. The method of claim 20, wherein the enforcing comprises blocking, by the computing device, transmission of unauthorized transmission between the first and second interfaces.
