Haha. Yea, should be good. Needs all the carpets cleaned and a new stereo and it'll be sweet for a year

lol, because I can afford fixing an old beamer? ended up getting a N16 Pulsar fro ~3k on raod

Any car I drive is, P plater with auto Ps.

So, looking for a new car now, only wanting to spend ~$3k, stretch it closer to $4k if I have to. Only need it for a year, two at the most, in which time I'll be finished studying and hopefully working full time. Looking at http://www.carsales.com.au/dealer/details/Nissan-Pintara-1992/AGC-AD-13614720/?Cr=3&sdmvc=1 at the moment, what do you guys think? any suggestions?

If I could delete your post I would. This isn't a discussion concerning whether we believe in the types of punishments currently in place, so I'd ask you to refrain from trying to create such an argument.

ECU is just not feasible, end of story. I can't do anything about that, I'd love to use it, trust me, but I can't. GPS will be there. Do you perhaps have ideas for other sensors? Again, it would be awesome to tap into the ECU, but there's no way I can create comms systems for every bloody model out there.

Sorry, thought we were talking about going off road. Yes, detecting a burnout is a current issue I'm having. To an extent, accelerometers can detect speed. Acceleration (Gs or m/s^2) over time (seconds) will give you speed (m/s off the top of my head). When I do testing I'll have to see what the reading differences are like between say a burnout, and simply revving the motor. But since the accelerometer can detect acceleration and deceleration you can see if the car is static. So, knowing that, we can possibly recognize if someone is doing a burnout. We take into consideration whether the car is static (making sure that acceleration and deceleration are equivalent - hence the car is stationary.) and if the car is static and there's a large amount of vibrations, it is possible that you're doing a burnout. Again, need to compare revving the engine to a burnout and see how clear the difference is between them.

An accelerometer with a high enough resolution and 3 axis shouldn't have an issue with that at all... A GPS won't detect sideways movement. As mentioned above, pulling data off the ECU is practically impossible to do across all car models. They all use different electronic management systems before ~2001. Whilst I have to do testing, I'm confident that yes, the accelerometer will produce data that allows differentiation. It's a matter of analyzing that data and flagging it as such when recognized.

Nice one, I didn't think of that. Well, in theory, via the accelerometer you should be able to tell that someone has gone off road in the first place, and adjust expectations accordingly.

Besides for it unfortunately already being a bit late for that as the projects are fixed, It's an electrical engineering degree, so the thesis is more about designing and creating a device rather than fixing a social issue. My major is computer system and network engineering, this project fits in more to the computer systems side of things.

The video data size really isn't that bad, you wouldn't need a massive resolution but for the reason stated - privacy, I don't think I would. Concerning the GPS, it won't be tracking. Just because it can take position readings doesn't mean I have to record them. No, I'll be recording the speed zone they're in, and the speed they're doing, but likely not the physical position they're in. If that's possible anyway. I'd have to ask Vic Roads when I talk to them next. TD;DL I'd prefer not to record their position via GPS.

I don't want the device to have any control full stop. I believe that's far too dangerous, it will be making real time readings but won't be able to make safety judgments. So no. There's also a technical issue with that - connecting with the ecu to limit speed. On a newer car ~ older than 2001 it's fine, most of them have OBDII so you can connect using its CAN bus or other means. Any car older (and there's still plenty of them around) won't work with that system, so you'd have to individually design interfaces for each and every electronic management system. Even the R34 doesn't use OBDII, it uses consort, same with the s15 I think. I'm applying the idea in a manner that compliments the existing breathalyser immobilizer done in drink driving cases. ------------------------------------------------------------------------ At the moment the idea is to use GPS tracking to get the traveling speed and the current speed zone. This will be backed up by an accelerometer. So in cases where the GPS has gone awry on speed calculations you can pull a rough idea off the accelerometer and compare the two. You can also use the accelerometer to measure other things such as sideways movement, vibration, etc. So for example if someone is doing a burn out you MIGHT (and I do have to do testing obviously) be able to use the z axis on the accelerometer to identify it via the vibrations. I'm trying to consider other sensors as well that might help create a good picture of behaviors. ---------------------------------------------------------------------------- As for speed zone accuracy I'll have to look at that during testing and see how I can implement restraints or cool downs around it. Taking the example above - moving into a 100 zone from a 60, I might have to add a 15 second hold time either side of a speed zone change (so before the change and after), so that the system doesn't flag based on GPS stuff ups. Please, keep the conversation going! This is all very valuable for my implementation research. I'm especially keep on opinions on it all and may even ask people if I can quote them, as I'll have to talk about stakeholders in my reports and you guys (motorists) are obviously a major stakeholder.

Well we just saw an extreme example in another thread with the gent doing 180Km in the S15 on the way to Bulla, but l'll use it anyway. We all know he has lost his license. Full stop. But what do people thing about perhaps approaching driver punishment differently? In a manner that allows him to keep his car? I mean, we allow drink drivers to continue after several offenses, we just chuck an immobilizer on their cars, so why can't we approach 'hoons' in the same way? I'm designing a device to monitor driver behavior for my thesis at uni. Only at the proposal stage at the moment but it's most likely going to use a 3 axis accelerometer and a GPS tracker. IT won't immobilize but record and report driving behaviors. Already talking to Vic Roads about it too, might get some sort of sponsorship, we'll see what happens. Anywho, any thoughts? Ideas? Anything you guys as drivers would like to see in such a device? Discuss! Thanks, Teir.

You're a touch late on that one... So, as for news (if anyone was interested). He won't pay. Insurance is giving me $3k. He owes me ~$2600 still, but it's not really worth my time and $, especially if HE doesn't have money to begin with. Yet to send a formal letting of demand, waiting on final settlement with JCI. And no, they didn't write it off, they can't since I'm not covered by full comp - at least that is the impression I'm receiving.

They would do that? I mean, I'm only covered for 3k if an uninsured party hits me. It's not full comp... If this is the case that'd be awesome. Much much bloody simpler.
