Summary of change:
'''Traction Control''' ...having a big engine with huge turbo and rear-wheel-drive is really fun, but we don't want this fun always (especially at high speed cornering on narrow roads). - So I have the idea that I need some traction control implemented... For the first time I don't speak about fancy stabilizing system with angle and G sensors utilizing brakes, and so on.. It's just a simple idea to control wheelspin when boost is suddenly too much. For a simple installation we already have: * Stock wheel angle/speed sensors (VR at all wheels from ABS system) * Control over excess power by playing with ign retard and fuel-cut What we need: * Some extra electronics to process the four VR signal ** we are sending in an ARM board (just hours before layout completion) that is capable of this (with very good trigger and AD inputs, power and analog output capabilities, and networks, of course) * Some logic -probably the good-old PID algorythm- to reach the limited slip Tell me your thoughts! Simple is good! Have a look at MembersPage/DavidBlades/TCSInputs I don't think it's very up to date though. I have a couple of promising algorithms in development based on just wheel speed sensors for working out what is slipping. Corners have a big impact on expected speeds... Really must get that Matlab finished... Links: [http://www.racelogic.co.uk/?show=Traction_Control-Technical-How_it_Works Racelogic aftermaket TC]
