Which technology does Audi use for its self-driving cars?

I've heard that Audi has some impressive self-driving cars, but what technology do they use to make this possible?

Audi uses a combination of lidar sensors, radar, and cameras to develop their self-driving technology, allowing for a 360-degree view of the vehicle's surroundings.

Audi partnered with NVIDIA to use their artificial intelligence technology in their self-driving cars, enabling them to continuously learn and improve their driving capabilities.
