So I was screwing around on some snowy roads today, and I started to wonder how the vehicle knows that it is still moving when all of the tires are locked up...
I mean, the VSS is gets the signal from the tranny, and if you lock up the wheels, the tranny stops too.
So I thought it could be inertia driven, but then why wouldn't it unlock your brakes for you on a steep decline?
So, for the brains out there, why doesn't the ABS unlock the brakes when you are not moving? How does it know that the vehicle is moving when the Wheels, axles, and tranny are all stationary?
Just curious, and wondering if whatever part makes it not unlock at a stop could potentially fail, causing all sorts of grief and mayhem.
Thanks,
Dan
