Great videos, subscribed!

I understand how the car can determine the intended path (by driver inputs), but how does the car "know" the actual path it is on in order to make the proper adjustments? Is it monitoring the forces from the road through the tires?

[EngineeringExplained]

@PixelBanger Not entirely sure, though I would assume it would use an accelerometer (or multiple) to feel the forces on the car. Once the tires are pointed one direction but there isn't an opposing force (via the tires) and no acceleration is felt, the car could assume it was sliding.

The question here is "How would a car knows when it is sliding?", Is there some sensor. gyro of some kind? I think an explanation on this should be included in this video; 'just saying! Overall, NICE!

Stability control makes an over or under steering vehicle into a neutral steering one at the expense of speed (since power is reduced and brakes are applied), a neutral steering vehicle can still skid into the ditch, it will just skid into the ditch with all 4 wheels equally losing traction.

@marcusthedog Well, a lot of sources. The most help came from researching Ford's AdvanceTrac stability control system, they did a good job of explaining it. As for most of my material it either comes from online or reading of automotive engineering books.
