I've read that power steering provides little or no assistance at the center and more as the wheel is turned farther from the center. Something more or less like this, where X is the steering position, Xo is the center steering position, and f is the function mapping the steering displacement to steering assist:
Assist = f (X - Xo)
Assuming that's more or less correct, how does the power assist "know" where the center (Xo) is? Does it a follow from the steering/suspension geometry, or is there a specific adjustment for Xo, for instance, on a rack and pinion steering, marking a particular point on the rack?
