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.

*Losing, for starters :P.

I'm meant to be doing an assignment myself; so not looking into it too deeply, I'll just ask one thing for now ; are you proposing this is implemented into every car (and eventually into some real-time feedback, with a devoted police unit or something of the like) - or rather as a disciplinary measure, such as the interlock, where you'd only have to have this provided you had an offense requiring this as a consequence? Or purely as a method of study for driver behaviour?

Would there not be a lot of grey area? I would imagine the lack of context would perhaps make it difficult to establish things such as the cause and effect of behaviour (correlation vs. causation).

Sounds pretty big brother to me also, jus' sayin' :P

Drink drivers still lose their licence for a set period too; the immobiliser only comes after the person has got their licence to drive back afaik.

I do agree that something similar should be put in the cars of people coming off suspensions for ridiculous offenses, like 40km/h+ over.

Really though, if the government wanted to stamp out excessive speeding, we would have cars from factory/import fitted with speed governors that maxed the vehicle speed out at the highest post speed on Victorian roads (110).

Want to stamp out speeding altogether? Then you have a system of speed signs that transmit a signal to governors, altering the maximum speed the vehicle can do on that section of road and thereby making speeding impossible. Or you could make the fines ridiculous, like $1000 for 0-10km/h over...then watch everyone stay at least 5 under the speed limit at all times. Bit like littering fines in Singapore. Will it ever happen? No. Because governments, particularly Victorian, want you to speed. Revenue projections are made based on estimations of issuing fines. Budgets depend on people breaking the law. It would be shooting a big hole in the proverbial foot for a government to spend money on losing money.

Some points to think about...

Cost to implement this would be extreme... Also if its broadcasting a signal saying "Speed Limit is xxx here" it would need to do it at the start of the street... So close to the corner of a 50km and 80km road for example. You've just turned from one road onto the other, which is the correct speed limit if you're receiving 2 signals?

GPS is another solution, I've got software on my phone which tells me the current speed limit for the road I'm travelling on (Trapster) as well as my current speed. Within 10 meters or so of a changed speed limit sign, it alerts me.
However GPS isn't always great quality in all locations... Really cloudy or rainy days lowers accuracy, as does driving through the CBD with lots of tall buildings around.

Sometimes when I'm on a 110km freeway, GPS spears me off to a sidestreet 50m to my left and yells at me that I'm doing 110km/h in a 40km/h school zone...

In this situation, would it send an alert to my "speeding probation officer" telling him to lock me up and throw away the key? How would I prove I wasn't speeding, if the 'evidence' shows that I was.

If this is linked to speed limiting the vehicles, would it slam on the brakes for me? down to 40 in a 110 zone?

Now though... Next Gen GPS Technologies are being tested to replace the current GPS system which is prone to "hacking" from localised transmissions. So one day the GPS issues I've just mentioned could be null and void. Until then though, I don't think we possess the tech / money to make this work effectively.

Most trucks are speed limited.

most new GPS systems show you the current speed of the road you're on(mine works really well)

Design a little black box that gets put in after X offenses that uses the GPS systems speed zones, and the trucks speed limiter.

Truck speed limiters are a bit different, they don't need to think about the current road speed limit, they just kick in at 110km/h as most of the occasions that truckies would speed is on the long straights where they trying to save time (Melbourne -> Sydney etc)

If I turn from a 60km/h road onto a 110km/h highway onramp, I want to be able to accelerate to 110 right away... if GPS data is erroneous (it does happen) then it may think I'm still in the 60 zone and not allow me to accelerate up to the speed that traffic around me is doing. Horribly dangerous.

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.

How about some simple video footage? "Hoons" have mandatory camera(s) installed dash/rear whatever, with a live feed to a central hub. The hub would be scare tactic if its disabled/blocked as someone may be viewing the feed in real time.

What's different about that compared to GPS? If it's real time "they" will still know where person X is at all times... GPS and sensors report back data in numbers and letters, video does the same thing except with images...

the downside is the amount of data that needs to be stored via a video live feed..

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.

Why don't you do your thesis to reduce the road toll. 98% of accidents are due to driver error and not speed related at all. It's just speed makes more money.

It's funny, I remember a German expert coming over as an advisor for the government to help in reducing our road toll...he recommended that we fix our roads, lift our speed limits and train our drivers. Well that was a waste of our money wasn't it.

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.

sounds pretty good, although i dont think it could always work ie 4x4s could slide, do burnouts etc and just claim they were doing some 4wding

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.

An accelerometer isn't going to know the difference between a burnout or a slide compared to cruising along at 60 on a rough road... or turning a corner. Unless you combine it with GPS which adds in the speed factor to the equation... but its still not reliable enough...

Pulling Data from the front and rear wheel abs sensors and ecu's speed would be able to accurately detect a burnout or powerslide. The only time that the rears should be turning faster than the fronts is during a burnout or emergency braking...

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.

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
