What kind of technology is used in the Audi A7 for its advanced safety features?

I am impressed by the safety features of the Audi A7, but I am curious about the technology behind them. Can anyone provide more details on this?

The Audi A7 uses a combination of sensors, cameras, and radars for its advanced safety features such as adaptive cruise control and lane departure warning. In addition, it also has a multi-collision brake system to automatically brake after a collision in order to prevent or minimize further accidents.

One of the key technologies used in the Audi A7 for its safety features is the Audi pre sense safety system. It includes features such as pre sense city, which can detect pedestrians and vehicles and initiate braking if necessary, and pre sense rear, which can warn and prepare for a potential rear-end collision.
