How does the Active Lane Assist feature work on the Audi A8?

I have heard about the Active Lane Assist feature on the Audi A8, but I am not sure how it functions. Can someone explain it to me in more detail and how it compares to other lane keeping assistance systems?

The Active Lane Assist feature on the Audi A8 uses a front camera to detect lane markings and keeps the vehicle within its lane by gently steering the vehicle. It goes beyond traditional lane keeping assistance systems by also monitoring the driver's steering inputs and ensuring they are in control of the vehicle. This feature is especially helpful on long highway drives where driver fatigue can increase.

I have been using the Active Lane Assist feature on my Audi A8 for a few months now and I can say it has really improved my driving experience. It is very accurate and reliable, and I have noticed a decrease in drift and lane changes. It also works well in both day and night driving conditions.
