Could they just use AFDX?

Two mutually exclusive networks is a good idea, and leveraging Ethernet as a standard for automotive networking is brilliant. I'm surprised it has taken this long to come up with that idea. Once the network protocols are in place as standards then all types of innovative products the link the home and business and the vehicle can be developed.

Timothy Lau I fully agree, your quote.. "Standardization is essential as a major enabler for new and innovative in-vehicle applications"" BUT, after 30 or more years there are still no standardization on the most basic of automotive systems, the "PCM or ECU" computer module for EFI engines. Even though the majority of EFI engine sensors are the same, ie TPS, MAT, Oxy, EGR, & a dozen more/ Every manufacturer is and has a different engine "PCM" computer. PCM's and change year to year & model to model - Even within the same Auto manufacturer. It is way past time for Tough standardization for engine management, starting with the EFI computer. Actually It's time for a mandatory, form, fit, function, O.S. & wiring I/O, right down to the sensors. And that's only the basic engine management. there is also the computer management in other systems,,, Suspension , braking, BCM (body control module), Collision. Do you know that 25, 50 or more processors are in most modern Automobiles - And with NO standardization. Until there is standardization in this arena, there never will be a standardization. Not to forgot the frightful cost in development and production costs. How on Earth can any College or University train Automotive Techs' for modern autos ?? Well effectively.. they can not. When there is standardization,, it will start. Yes, we have a mess. But, wait - Now come the Hybrids, Ev's and,,,,,OMG. At least they could settle on battery packaging, like small Battery Hopefully standardization will ignite in all electronic systems in the Auto market, and glean out the unneeded. If you look into the after market engine management computers and programming, notice that the testing is completed via the most common computer the "P.C.". Hopefully standardization will as well.. Note the low cost software ! After all their Cars not Space Shuttles.... Good Luck, it's a complicated snake of wiring... Michael..EE CE

From safety point of view , it is essential to keep two mutually exclusive networks in a vehicle. One for Engine control, braking, air bag and such systems and the other for infotainment and other applications.
