AN OVERBROAD PATENT ON IN-FLIGHT/IN-CAR NETWORKING - This application from Lear Corporation seeks to patent the idea of...a gateway from the Internet to a vehicle! 10 minutes of your time can help narrow US patent applications before they become patents. Follow @askpatents on twitter to help.

QUESTION - Have you seen anything that was published before Dec 15, 2011 that discusses:

  • embedding an HTTP request in a CAN bus-compatible message and transmitting the CAN bus-compatible message onto a CAN bus

If so, please submit evidence of prior art as an answer to this question.. We welcome multiple answers from the same individual.

EXTRA CREDIT - A reference to anything that meets all of the criteria to the question above AND ALSO is compatible with Ethernet or communicates with a Server


Summary: [Translated from Legalese into English] A which translates from HTTP to the standard vehicle bus: controller area network (CAN bus) and a controller on the vehicle which responds to the HTTP request.

  • Publication Number: US 20130159586 A1
  • Application Number: 13/712,293
  • Assignee: Lear Corporation
  • Prior Art Date: Seeking prior Art predating Dec 15, 2011
  • Open for Challenge at USPTO: Open through Dec 20, 2013
  • Find Prior Art on Google: Google Link

Claim 1 requires each and every step below:

A control system for a vehicle, the control system comprising:

  1. a gateway controller configured to embed an HTTP request in a CAN bus-compatible message and transmit the CAN bus-compatible message onto a CAN bus; and

  2. a remote controller configured to receive the CAN bus-compatible message from the CAN bus, extract the HTTP request from the CAN bus-compatible message, and create an HTTP response to the HTTP request.

In English this means:

A vehicle control system, comprising:

  1. A gateway from the Internet (HTTP) to a vehicle (CAN bus)

  2. A controller on the vehicle which receives CAN bus, extracts HTTP request and creates an HTTP response.

Good prior art would be evidence of a system that did each and every one of these steps prior to the Dec 15, 2011.

You're probably aware of ten pieces of art that meet this criteria already... separately, the applicant is claiming using gateway which ALSO is compatible with Ethernet or communicates with a Server

"Controllers communicate through a CAN bus in a vehicle and connected through a gateway controller with an Ethernet network” from the Applicant

What is good prior art? Please see our FAQ.

  1. In 2002 the following paper (A publisher/subscriber architecture supporting interoperability of the CAN bus and the internet) was published:


    The paper specifically describes a CAN bus, a gateway, and the internet

  2. There is also a 2009 paper (Bringing Best Practices from Web Development Into the Vehicle):


    This describes an http wrapper around the CAN bus so http messages can be sent to the vehicle, translated down then issued to (for example) the ecu


NASA actually did this in the early to mid 2000's with a 757 "Aries" flying lab aircraft. A FIOA request to Langley will turn up some of the design documents. Ask for aft cockpit as well as ARIES and 757.




Some of the 737 documents from NASA might be relevant too.



I know for certain of prior art: see

"SAE J 1939 Over Real Time Ethernet: The Future of Heavy Duty Vehicle Networks" doi:10.4271/2012-01-1988 Author: Massimiliano Ruggeri of IMAMOTER C.N.R. – Institute for Agricultural and Earthmoving Machines, National Research Council of Italy

I will call this page to Prof. Ruggeri's attention.


Dear Lear Corporation I'm Massimiliano Ruggeri, a Researcher of the National Research Council of Italy. We are working on Embedding CAN on a Ethernet communication and vice versa since 2008. We work both on wireless over WI-FI to synchronize vehicles and to perform fleet management and on Wired Ethernet for in-machine communication. We also designed and published several papers on a CAN/Ethernet Gateway design and testing and we also implemented it.

The CAN message Vs TCP/UDP/IP message under HTTP is well explained in the paper 1), and in the other papers the analysis is performed on specific CAN networks for heavy-duty and for Agricultural vehicles, where international standards set a lot of requirements.
