How does Audi A8's Active Lane Assist work?

I'm curious about the technology behind Audi A8's Active Lane Assist and how it keeps the car within its lane. Can someone explain the mechanics behind it?

The Active Lane Assist system in Audi A8 uses a camera mounted on the windshield to detect lane markings and monitor the car's position in the lane. It then adjusts the steering if the car starts drifting out of its lane. My advice is to still keep your hands on the steering wheel for safety reasons. -Mark Smith

The system works by analyzing the road ahead and determining the ideal steering angle to keep the car in its lane. It can even handle slight curves and bends in the road. However, it's important to note that the system may not work in adverse weather conditions or on roads with poorly marked lanes. -Alicia Hernandez
