How does the Audi A8's active lane assist work?

I'm curious about how the active lane assist feature in the Audi A8 helps with lane keeping. Does it use cameras or sensors to detect lane markings?

The Audi A8's active lane assist uses a camera mounted on the windshield to detect lane markings. It then gently nudges the steering wheel to keep the vehicle centered in the lane. It also works in conjunction with the vehicle's radar sensors to monitor the distance and speed of surrounding vehicles.

In my experience, the active lane assist in the Audi A8 is very helpful in preventing unintentional lane drifting. It's especially useful on long highway drives. Just make sure to always keep your hands on the steering wheel, as it is not a hands-free driving feature. Enjoy the smooth ride and advanced technology!
