How quickly can a car measure the available traction and respond to brief loss events?
Can on/off detection response times and recovery strategies be improved for black ice (and hydroplaning)?
If a car hits black ice, should it power itself down or should it max out the CPU looking for the instant traction returns on any wheel and do whatever it takes to try to slow down?
Modern traction control systems available on production cars and motorcycles have a polling rate of up to 1000Hz. You don't need self driving tech to handle most low traction situations.
Black ice is an exception because once you start sliding on it there is not much you can do to regain control except ride it out and hope you don't hit anything before you get out of the ice.
Can't do anything while you're on the ice, but once you're past it you may still need to react to avoid a collision, and you may find yourself in a sideways slide at that point. So a control system that knows how to handle a drift could be beneficial at that point.
My mouse has a 1000Hz polling rate. Is 1000Hz really good enough for excellent traction control? I'm sure it's fine for most situations, but the small amount that it's not good for are probably the ones that matter the most.
I expect you could turn your mouse's polling rate down to 200Hz and not notice any difference, even gaming. Also, a mouse is a very precise control; much more so than the controls of a car. I could certainly be wrong, but my intuition suggests that a 1000Hz sensor polling rate would be fine for an autonomous vehicle.
