Here's another good one that came up in the suggested videos:
It shows what Toyota calls auto LSD. It uses the brakes to limit wheel spin on an open diff. I think stabilitrack may do something like this....
I'm pretty sure camaro's have a torsen diff still? There's also a video of one of these on youtube, although it did not help my understanding of how the load is transferred with this setup.... lol
A positraction differential uses a set of clutches in between the left and right side axles to allow slip under high differential speed, as when turning.
An automatic locking differential uses differential inertia created by wheel spin to mechanically engage an axle lock. These usually will not activate over 30mph or so, giving you an open differential above that speed. These are mostly found in trucks.
