The assistance systems follow the philosophy under which Audi developed the new TT* and TTS*: They are tailored to the driver and relieve him of certain tasks so that he can concentrate fully on the road.
Among the standard equipment in the new Coupé is the secondary collision brake assist, which is activated in the event of an accident. In many situations, it prevents the car from continuing to roll in an uncontrolled manner, and it also activates the car’s interior lighting and hazard warning system. Another standard feature is the rest recommendation, which lets the driver know when he is starting to get fatigued.
The optional Audi side assist helps the driver when changing lanes. At speeds of 30 km/h (18.6 mph) and above, its radar sensors monitor the road behind to a distance of roughly 70 meters (229.7 ft). As soon as the system classifies another vehicle in the blind spot or approaching rapidly as critical for a lane change, it warns the driver via a bright LED on the relevant exterior mirror. If the driver still activates the turn signal, the indicator flashes several times.
Audi active lane assist, which comes standard in the Audi TT 2.0 TFSI and the TTS, becomes active at speeds of above roughly 65 km/h (40.4 mph). A video camera in the interior mirror identifies the lane markings on the road surface. If the new Audi TT or TTS begins to approach one of the lane markings without a turn signal being activated, it guides the driver back into the lane with a gentle pulse of the electromechanical steering system. In the MMI user control system, it is possible to configure a vibration in the steering wheel as feedback and define the time of the intervention. In the “early” setting, the system assists the driver in driving down the center of the lane.
Another optional feature, the camera-based traffic sign recognition system, also uses the data from the video camera. It compares data with the navigation map to indicate speed limits, conditional speed limits and no-passing zones. The system is purely informative; it does not intervene.
There is a choice of three systems for safe and easy parking. The top version – park assist – can steer the new TT and TTS backwards into parking spots. At moderate speeds, it measures the spaces using its ultrasonic sensors. A notification appears in Audi virtual cockpit when the system finds a suitable spot. As soon as the driver now puts the car into reverse, the system assumes control over the steering via the electromechanical steering system and the driver only has to accelerate, shift gears and brake.
The park assist will maneuver forward and back multiple times if necessary. It provides similar support when exiting parallel parking spaces. The 360° display warns of obstacles to the sides.
