Reallife Acceleration Profile

Hi

While driving a turn through town I measured the three accelerations¹ and three rotations², captured a video of the drive and tracked the GPS data.
There are some roundabouts and narrow curves, acceleration/deceleration (not too high though, I only drive a Citroën Xsara Picasso ) some speed bumps (to slow down traffic), etc.
The data give me a good understanding of the accelerations and motions during a reallife drive. I was specifically interested in verifying my theoretical calculations of the accelerations and forces; more specifically what accelerations and forces can be mimicked by tilting the seat.

The dataset consists of the actual measurements (csv file, here), of a Google Earth kml file (so you can follow the route, here) and a video file of the ride. The video gives you a better understanding of the actual drive and you can see the speed on the dashboard.
Video part 1, part 2

There is a small offset of about 10 sec between the video time and the acceleration time.

Have fun too. I had/have a lot

¹ heave, linear vertical (up/down) motion, essentially bumps in the road; sway, linear lateral (side-to-side) motion; surge, linear longitudinal (front/back) motion, essentially acceleration and deceleration
² roll, rotation about longitudinal (front/back) axis; pitch, rotation about transverse (side-to-side) axis; yaw, rotation about vertical (up-down) axis, esentially centrifugal force in curves

Re: Reallife Acceleration Profile (Klausenpass added)

Hi again

I had a ride up and down the Klausenpass (or here in English) and measured the accelerations.
Now the nice thing is that the Klausenpass actually also exists as a track for rFactor. You can download the track here (thanks to Wawotsch )

I drove up, down and up again. Each dataset consists of three files: Video footage, gps data (actually kml format) and the acceleration profile.

Up: Video footage, gps data, acceleration profile
Down: Video footage, gps data, acceleration profile
Up: Video footage, gps data, acceleration profile.

I have not done intensive analysis yet, just a quick comparison between the Force-Profiler output and the real-life data.
And it's fun to drive with rfactor on one screen and the video footage on the other

Thank you bleco for your reply. LOL

Nope, I didn't find a Picasso for rFactor so I took the Citroën Berlingo.
If you can point me to a Picasso, I'd love to drive the track with it. And you can drive yourself by matching the video footage with your driving.

You can only trust me

Again, if you let me know what car we can trust, I will try it. Just, I don't want to compare necessarily the acceleration values of a racing car with real data from a French family car

So 0.2 x 5-6 = 1-1.2 g. Depending on the track and car, this will certainly be the case. A Picasso (no suction) will fly off the curve of a track at around 0.8 g…

Luckily enough this is what I tried and succeeded in real life!

The benefit of Klausen is that it has been designed very realistically in rFactor and I can drive it with my real car - and additionally it's a lovely landscape worthwhile a ride anyway.
Any other suggestions (accessible in reality and available in rFactor or any other program) are welcome!
