How does the autonomous parking system work on the Audi A8?

I've heard that the Audi A8 has an advanced autonomous parking system. Can you explain how it works and if it's reliable?

The Audi A8 uses a combination of sensors, cameras, and algorithms to park itself. It has the ability to detect and avoid obstacles and can even parallel park with minimal input from the driver.

I've been using the autonomous parking on my Audi A8 for a few months now and it has been very reliable. It has never had any issues with parking or detecting obstacles.
