Vehicle 2 Vehicle Communication Questions

Question

I have a rare opportunity to meet the man in charge of implementing vehicle 2 vehicle communication for the US Department of Transportation with 2 others in a few hours.

Do YOU have any questions for him?

I know this is a little outside the normal, but this is a 'reverse' thread and I felt he has some great knowledge on the subject that I want to share with this community.

I'll post his answers later today to his questions.

Ask about V2V implementation, privacy issues, use cases, or if you've thought of a great way to use V2V and want me to share it with him, he can at least think about it. He is in charge of panel that creates the standard. Or anything else...

I'm more interested in sharing great uses for V2V if you can think of any... I'll give credit, promise... particularly because he may not hear them on a day to day basis.

Here's a good primer on the subject if you want to contribute something original. http://www.popularmechanics.com/technology/gadgets/news/4213544

Answer 1

I would definitely ask about security and privacy. What data about my vehicle is available to another vehicle? etc

Answer 2

How do the V2V determine which vehicle to communicate to, expecially at speeds greater than 60 mph?

On a freeway / highway with 5 lanes on each side, during rush hour, how far does the communication go? Does the V2V communicate with vehicles on the other side of the freeway?

Is GPS considered as part of V2V?

What is the maximum supported distance for V2V?

Can V2V broadcast on Cell-Phone frequencies or FM radio frequencies?

Answer 3

I would ask how they are approaching the problem, and in particular if they took current research results from vehicle wireless sensor networks, since that's an area I was researching into when in grad school.

Also some published papers on the actual implementation and experimentation results would be great.

Answer 4

Security! What is in place to stop a couple clever teenagers from griefing v2v enables cars with false vehicle positions? I'm especially wary if the car wants to take control from me (automatic braking, etc).

Answer 5

I'd love to see this integrated with traction control. It would be invaluable if oncoming cars broadcast recent moments when they had less traction.

Using this same idea, integrate v2v with radar detectors. In this case drivers would be more aware of the traffic cop hidden around upcoming corner.

Answer 6

Why is a solution that requires multi-vendor standard compliance a better alternative to the consumer than existing sensor packages that accomplish (mostly) the same thing for only the cost of hardware and implementation?

secondly: how can i disable mine?

Answer 7

Retransmission:

Retransmission could greatly improve the lifetime of useful information. By useful I mean stuff like "it's slick right here", or "cop right here". A message that is continually retransmitted would long out original producer.

Using the black ice example.

north bound car x find black ice as GPS pos B. car x passes southbound car y and transmits this information. Car y is at GPS pos A and now warns that it will soon be approaching GPS pos B and that it might be slick. While at position B car y doesn't find it to be slick. car y passes northbound car z at pos C and retransmits car x's message about the black ice with the added info that the southbound lane might not be slick. car z warns its driver that is approaching GPS pos B and that the northbound lane might be slick.

This could continue on with each car adding information about which lanes a slick. Car with different findings would not erase each other, just add.

the issues i see here: protocol for position sensitive information time sensitive information (the message eventually needs to go away). ability to add to messages, vehicle voting on slickness etc.

Answer 8

Ask if they plan to implement a 'get out of my way' functionality for ambulances etc and how much you need to pay him under the table to get such a box.

Answer 9

The guy came and delivered a presentation. Every question I had from you guys he covered. If I didn't answer correctly, please let me know.
