Trivial hacking is probably unlikely. Vehicles generally use CAN bus, but whether or not the camera data is available on the bus... I have my doubts, but if it's there, that'd be pretty cool. My guess would be there's a dedicated image channel off the main bus--but that's just a guess. I'd be interested in knowing if it's on the general network. It is peer-to-peer so in theory it can be deterministic, so maybe it is.

Yes, it's definitely not running over CAN as CAN doesn't provide enough bandwidth for cameras. Usually the cameras are connected using LVDS or in newer cars, ethernet.

Lvds? I assume the camera is some feet from the processor. Can lvds really be usedthat far?

[davelnewton]

I don't know why not; IIRC FireWire was LVDS (4+m), and LVDS doesn't specify ("care about") distance, just loss between driver and receiver. I vaguely recall lossless transmissions between 10-30m, which is more than enough for a vehicle.

Thanks for the follow up!
