New turn signal light in the Audi A8
Ingolstadt - In the new Audi A8, the turn signal light consists of
lighting elements that illuminate in a defined sequence; this makes it
easier for others to perceive the driver’s turning intentions, even
under difficult conditions.
the new Audi A8, the turn signal lights will now indicate the turning
direction in an innovative way, which has the potential to significantly
enhance traffic safety. That is because the lights provide a visual
signal that can be clearly and quickly perceived, even at long distances
and in poor visibility.
Each of the enhanced headlights contains18
light-emitting diodes arranged in a strip that is subdivided into seven
blocks. Each tail light contains 24 LEDs in eight segments, which are
used to dynamically indicate the turning direction. During flashing, the
blocks are sequentially activated at 20 millisecond intervals, from the
inside outwards in the desired turning direction.
After 150 milliseconds, all segments are bright; for another 250
milliseconds they illuminate with full intensity. Afterwards, the turn
signals go dark before repeating the lighting sequence.
Considering their capabilities, the Audi Matrix LED headlights can be
regarded as a cutting-edge innovation. In each headlight, 25
light-emitting diodes generate a highly variable high-beam light. When
the on-board camera detects other vehicles ahead, the Audi Matrix LED
headlights mask the relevant sections of the high-beam by dimming or
shutting off individual diodes. Very bright illumination is preserved in
the remaining zones.
The Audi Matrix LED headlights also feature navigation-based cornering
lights and, in cooperation with the night vision assistant, a marker
light that warns the driver of pedestrians in the dark and which also
alerts the pedestrians.
Audi will be presenting the upgraded A8 in September at the IAA
International Motor Show in Frankfurt.
