Self Study Program 629 – Audi TT (Type FV) Vehicle electrics, electronics and infotainment

VAG SSP 629. All versions of the new Audi TT come with a generous range of standard equipment, particularly the MMI radio and the electromechanical parking brake. Alongside the S sports seat with numerous leather and trim variants, options include the advanced key, hill hold assist, high-beam assist, the LED interior  lighting package, front seat heating, and the storage and luggage compartment package.

On the infotainment front, customers can choose from a wide range of options. The connectivity package features the MMI touch system incorporating a touch-sensitive touch pad. At the top of the modular range is the MMI Navigation plus with its large flash memory, two card readers, DVD drive, Bluetooth interface and voice control system. The T30 chip from the Tegra 3 series by market leader Nvidia, which is installed in the new-generation Modular Infotainment System, controls all in-car navigation and multimedia functions and displays content in the Audi virtual cockpit.

The Audi connect system complements the MMI Navigation plus perfectly – it connects the new Audi TT to the internet using the high-speed LTE transmission standard. The integrated Wi-Fi hotspot means passengers can surf the internet and e-mail as they please, while the driver can rely on the customised Audi connect services.

The infotainment package is rounded out by attractive optional equipment. The Audi Phone Box  conveniently links mobile phones to the car. Its centrepiece is a universal planar aerial which is integrated into the storage tray in the centre armrest. Thanks to close-range coupling, the phone communicates with the flat planar aerial, which uses an amplifier to transmit the signals to the car aerial.

The Bang & Olufsen Sound System features a 14-channel amplifier and 12 loudspeakers; the bass loudspeakers in the doors are illuminated discretely by fibre optics.

Highly intelligent assistance systems make driving the new TT an even more pleasurable experience. As an option, the car can be equipped with Audi side assist, which uses rear-mounted radar sensors to help drivers change lane more safely; camera-based traffic sign recognition; Audi active lane assist, which helps the driver if necessary by steadily correcting steering or warning him/her if there is a danger of unintentionally drifting out of lane; and the park assist system with ambient display which  independently guides the car into suitable parking spaces.
