#20950 - traction control /speed governing
First off a thank you for reading this subject. I'd love to find some base source code to get me started on my way.

I'll give you a quick run down:

INPUT #1: 4 speed sensors that generate a voltage.
INPUT #2 Speed of 4 wheels is averaged. This value is the "Rule Speed". Normal operation will see a 0-1.99% variance ignored.

RULE #1 = 2-5% variance between the four sensors. This will be the inflection point. Adjustibility here is the tuning of the system I believe.


OUTPUT #1 = 2v
OUTPUT #2 = 12v Relay oscillating at 5hz
OUTPUT #3 = 12v Relay off


ALGORITHM: If one or more wheel(s) is outside RULE #1 from the other wheels, implement OUTPUT #2 for 1.0s. If RULE #1 no longer violated, end. If RULE #1 is still in violation, add OUTPUT #2 for 1.0s. If RULE #1 no longer violated, end. If RULE #1 still is in violation, add OUTPUT #3. OUTPUT #3 will end rule violation, once violation has ended, cease OUTPUTS.

Ability to add RULES to map that will employ existing 3 OUTPUTS.


Does this sound familiar to anyone? It is in theory a basic speed governor for 4 wheels. A rudimentary traction control system. Would anyone be interested in partnering on this project? I will be doing it with a Ford vehicle.
