What is Audi Pre-sense front in the Audi A7?

I recently saw that the Audi A7 comes with Audi Pre-sense front as a standard safety feature. Can someone explain what this feature does and how it works?

Audi Pre-sense front is a technology that uses radar sensors to detect potential collisions with other vehicles, pedestrians, and cyclists. It can also detect stationary objects in the path of the car. When a potential collision is detected, the system will first warn the driver, and if necessary, automatically apply the brakes to avoid or reduce the impact of the collision.
