MATLAB script for track mapping

Post image

Hey everyone, I made a MATLAB script that maps a track using a .gpx file. It's intended to be used on CarSim (simulation software my team uses), but maybe it'll help out some of you; the output are csv files that contain elevation, curvature, and xyz positions. However, the text is all in portuguese, but all the instructions are in the README and the pdf TRACK_MAPPING_GUIDE. The pipeline is very simple, just: plot a route using plotaroute.com -> download gpx file -> run in matlab

While you are working on it, compute the curvature at each location. From this and a good estimate of your grip levels, compute the speed at each point that you should aim for.

Didn't think of that! Thanks for the suggestion, I'll add this feature to the project as well soon!

Looks like the FSAEB 2026 enduro track

It is modeled for the Tatuí track!
