It seems acegis has beat me to the question >_>
(And sorry, acegis, for hijacking your thread

but the question is relevant, and I hate starting new threads for the same question.)
I have 3 cars -- a 2004 Ford Expedition, a 2005 Nissan Altima, and a 1975 VW Beetle. I'm planning to build a carputer in either the Expedition or the Altima. My dad's Nissan Titan (a bigass truck, for all you Euro's who only see small cars :P) came with a navigation system, and he can monitor all sorts of engine diagnostics. With just a small joystick to control, he can check fuel consumption, tire pressure, miles till empty, and much more. the OnStar program in most GM's comes with a similar feature -- OnStar can run a complete Vehicle Diagnostic and email it to you, or even read it off to you in the car.
What I want (and it might already be out there, or extremely hard to code) would be a full diagnostic to run on a carputer. As you have said, michbound, there are programs out there for fuel consumption, and that carputers can be hooked up to the OBD-II to see engine diagnostics. But I have also seen things such as a viper remote start -- when the car is hit, or broken into, an LED diagram of the car on the key shows the driver where. Something like that would be pretty cool in a car to show damage reports -- If somebody hits you in a parking lot, a small pressure sensor (I have the money, and would be willing to put them in bumpers, and side panels if at all possible) records the hit and will tell the driver later on the screen inside the car, and on the key immediately. I also plan to hook up a few cameras on the car (front, back, and
maybe sides) to record accidents. I've seen a website for a "crash cam" available in japan -- it records 15 minutes worth of footage, and continues to erase and re-shoot while driving. in the event of a crash, the entire scene is on film. One camera on each side would be useful, along with a back camera for backing up.
So if you don't want to read all of that above (just an explanation of what I'm looking for) read the question below:
Ok, ok -- so the list may be a bit long and complicated -- but do you know of an OS that could run it? I've seen linuxICE (
In
Car
Entertainment), and other Carputer OS's similar to that -- easy to run and navigate -- but
is there one out there that could manage a COMPLETE diagnostics program, along with a DVR Accident camera system?
