After developing a first cut of the software, he quickly learned that developing a slip control system goes way beyond the basic theoretical controls. Controls for closed environments like a test track with fixed maneuvers are pretty straightforward. The problem is when you start throwing in transient maneuvers and surface transitions. All of a sudden the problem becomes much more complex as Drew found when other people started driving his traction control on the road. I can definitely sympathize with Drew on this project after working as a controls and software engineer on abs/tcs and stability control systems for 17 years before quitting a few months ago. Head over to the Tesla Blog to read all about Drew's big adventure and don't forget to check out the videos after the jump.
