What is the Integrated Vehicle Dynamics system in Audi A6?

I have heard about the Integrated Vehicle Dynamics (IVD) system in Audi A6. Can someone explain what it is and how it works?

The IVD system in Audi A6 is a technology that integrates the functions of the electronic stability control (ESC), electronic differential lock (EDL), and traction control (ASR) into one system.

With IVD, the Audi A6 can automatically distribute torque to the wheels with the most traction, resulting in enhanced handling and stability while driving.

The IVD system also includes Audi drive select, which allows the driver to select different driving modes (comfort, dynamic, or auto) based on their preferences and road conditions.
