 Posted: 10:37 - 09 Mar 2015 Post subject: Motorcycle Data Logger |
 |
|
Hi Everyone!
I was just wondering if I could get some help from some of you. I’m a student in my final year of university studying Computer Science, and am designing a prototype data logger for use with motorcycles to try and improve safety.
For the project I need to get some feedback as to the features that motorcyclists, other than myself, would like from a product of this kind. The system currently measures speed, location, lean angle, wheel locks/skids, altitude, and temperature when the system is used on a journey. After the journey you can remove the memory card from the system and review your journey through a website.
I’ve made a simple website mock-up showing a real journey, which allows you to see the types of information the system can log and let you visualise.
I would be very grateful visit my website and fill out the quick multiple-choice survey to help me. If you have any additional feedback please reply below.
Website: www.benjw.co.uk
Please use the ‘?’ icons on the website to find out about the features of each widget.
Unfortunately lean-angle data on the website is erroneous due to a bug in the software, and has since been fixed.

Question 4 needs a checkbox for "Other", because "none of the above" interest me.

That seems like a lot of additional electronics where a modern mobile phone would work. That's what I'm currently using and it includes lean angle and I've just added heart rate too. The only thing about heart rate that I've learned so far is that it's not a function of speed.
I process it all for video (clicky for bigger picture).
https://dl.dropboxusercontent.com/u/188253/_bcf/testimage-tiny.png
The aim is to do a tour of Scotland and have all video/track/biometrics sorted. "Just because" - if you're wondering why. Hopefully it'll all be sorted and the process of generating it all will be smoothed out by then. There's a load of post processing for the video, I had to setup my own OSM server because I got banned for downloading too many tiles while testing.
I do like your googley maps variant, something I've done before from data captured from the original TomTom Go.
Also interested in "Wheel locks" and "Wheel slips" and how you are measuring those. Always thought it a bit of a shame that bikes don't seem to have the equivalent of ODBII.
Heat map is an interesting idea too.

Good point ! But no the data is all private and only available for you to see. The server does not store any data meaning that there is no possibility of anyone other than yourself seeing it. In the live version system there is an option to upload the data file from an SD card which will then display the journey.
I will also have an option to disable speed data, as i know a number of people (including myself) do not want this system to be used against you!
| Quote: | That seems like a lot of additional electronics where a modern mobile phone would work. |
I did consider using a mobile phone however they have a few limitations. Firstly most contain a GPS with a 1hz update rate meaning that they only update your location once a second. When measuring high speed cornering once a second is not accurate to map the data, as in 1 second the bike will be in a completely different place.
Applications on phones also consume a lot of power, and require to be mounted in order to accurately measure lean angles. My system is very low power and can simply be strapped down in your seat storage and will only need recharging every few weeks if used every day. It automatically switches off when the vehicle is static for a period of time.
My system also detects wheelies and stoppies (endo's) which is hard for a phone to detect, especially when in the riders pocket.
I really like your system though! You've got some really good ideas I haven't looked at. I'm definitely going to look at adding an HUD in the future so the rider can see live data. What HUD are you currently using for your system?
| Quote: | "Wheel locks" and "Wheel slips" and how you are measuring those |
I'm currently doing research into the best way of detecting wheel locks/slips
The three methods depend on measuring the wheel speeds using either a 'hall sensor', 'reed sensor', or 'IR sensor'. Wheel locks are determined by when the has has stopped spinning (also uses GPS speed to validate). Wheel slips are determined when the rear wheel is traveling over 20-30% faster than the front. This percentage is the threshold that wheels can slip in order to achieve maximum acceleration.
| Quote: | Or some kind of economy thing - selected gear vs rpm vs road speed etc |
I like those ideas, will look have at adding them. If you haven't filled out my survey yet just write them in the 'others' box
| Quote: | Question 4 needs a checkbox for "Other", because "none of the above" interest me. |
Question 4 has been updated to allow 'None of the Above' to enable you to continue to the next question without selecting an answer.
If an option is not there which you would like to log in an ideal system, please write it in the 'Others' box.
| Quote: | How will this 'improve safety'? |
It's aimed is to highlight rider errors which occur on a journey in order to try and get the rider to see their mistake and prevent them in the future.
This part of the system like Matt B said is not really aimed at experienced riders. The potential application is for use by motorcycle training schools to help the riders identify their mistakes when trying to obtain a licence.
It's part of the research side of my project
However I need riders of all age (16+) and experience to voice there opinions and take the survey as it will influence the project both now and after graduation.
| Quote: | The software already exists, works great and costs next to nothing |
That would be the dream! Unfortunately from my research it would be difficult to implement. Unlike cars there is no universal connection to the ECU, and like you said would require adaptors (many also need an additional signal converter). Unfortunately this is out of the scope of my university project.
I looked at buying the ECU adaptor for my bike, however for the cable, the required signal converter, and the software would cost >£300.
Thank you for all your input! |

Interesting.. I have noticed a little drift but I can fix that in post as required, although I don't need millisecond accuracy for my purposes.

Nice, although I have power to my phone so not that much of an issue. Of course the advantage for you is that you can still use your phone for navigation without worry that you'll miss data.

It's just a series of perl scripts that generate a series of frames which are converted to video. I then do manual merge and masking to generate the final output. All of the HUD type applications I found are just for use on track it seems, lap counters etc - totally irrelevant to touring about..

Yeah, this is the interesting stuff, but there are so many associated problems if a bike is in general use. Look forward to more info as you move on with your project. ____________________ Honda CBF125 ➝ NC700X

I can see that this would be great for those of you who have specific track day bike (and cars for that matter).
Especially if you compete on any level, gives you the data on your lap of any given track, overlay that with the image of and you can see where the improvements can be made.
Have it coupled with an RF burst transmission system to get data back to the pits in real time and you'd have an invaluable bit of kit for the weekend warriors and semi pro's a like
Did not see anything about brake input front and rear, but might be useful.
hope this helps

What software are you using to get the maps overlay onto your video? My action cam produces GPS data files but I haven't a clue what to do with them. |
