Audi takes to the race track with the sportiest piloted driving car in the world |
|
| Ingolstadt/Hockenheim, 14 October, 2014 (APA/OTS) - Audi has
developed the world's sportiest piloted driving car. At the German
Touring Car Masters (DTM) season finale, the Audi RS 7 piloted
driving concept car will demonstrate its dynamic potential and
driving capabilities for the first time on the Hockenheimring - at
racing speed, without a driver. |
"We are pressing forward with one of the most important trends in
the automotive world with our technical solutions for piloted
driving," says Prof. Dr. Ulrich Hackenberg, Board Member for
Technical Development at AUDI AG. "The utter fascination of this
development will be put on display at the DTM race in Hockenheim. A
lap time of just over two minutes and lateral acceleration of up to
1.1 g speak for themselves."
Audi has long been a driving force in the area of highly automated
driving. The brand's development efforts have produced a number of
spectacular feats. In 2010, for instance, a driverless Audi TTS*
conquered the legendary Pikes Peak mountain race circuit in
Colorado, USA. Audi has time and again showcased the potential of
the technology with demonstrations at the limit. With 560 hp and a
top speed of 305 km/h (189.5 mph), the Audi RS 7 piloted driving
concept car exemplifies Vorsprung durch Technik.
The Audi RS 7 piloted driving concept car on the race track
The Audi RS 7 piloted driving concept car is a technology platform
with which Audi is exploring the possibilities of piloted driving at
its most dynamic. On Friday, October 17 and Sunday, October 19 -
prior to the start of the last DTM race - the concept car will
complete one lap on the Hockenheim ring without a driver. The large,
five-door coupe is largely identical to the production model, but
its electromechanical power steering, the brakes, the throttle valve
and the eight-speed tiptronic that distributes the power to the
mechanical quattro drive system are controlled automatically.
There are two primary technological considerations during piloted
driving at the physical limit: the highly precise orientation of the
vehicle on the road and absolute control of the vehicle at the
handling limits.
The technology platform uses specially corrected GPS signals for
orientation on the track. Accurate down to a centimeter, these
differential GPS data are transmitted to the vehicle via WLAN
according to the automotive standard and redundantly via
high-frequency radio. Parallel to this, 3D camera images are
compared in real time against graphical information stored on board.
The system searches in each of the countless individual images for
several hundred known features, such as building patterns behind the
track, which it then uses as additional positioning information.
Control of the vehicle at the handling limits is another outstanding
feature of the Audi RS 7 piloted driving concept car. Comprehensive
on-board networking coupled with the highly precise control of all
actors relevant to driving enable the technology platform to drive
at the physical limits. The Audi engineers intensively investigated
piloted driving at the handling limits, putting the technology
platform through several thousand test kilometers on a variety of
routes.
To demonstrate its capabilities, the Audi RS 7 piloted driving
concept car will drive a clean racing line at the Hockenheimring -
with full throttle on the straights, full braking before the
corners, precise turn-in and perfectly metered acceleration when
exiting the corners. Forces of over 1.3 g occur during braking, and
lateral acceleration in the corners can reach 1.1 g. Tests on the
track in Hockenheim suggested an expected top speed of 240 km/h
(149.1 mph) and a lap time of 2 minutes and 10 seconds.
The race track is also the most demanding test bed for production
when it comes to piloted driving. The future systems must also work
extremely precisely and with zero errors in critical situations.
They therefore must be capable of properly assessing the current
situation even at the physical limit. This test bed provides the
Audi engineers with a variety of insights for production
development, such as for the development of automatic avoidance
functions in critical driving situations.
The lap by the RS 7 piloted driving concept car can be followed via
live stream (www.audimedia.tv/en). The broadcast begins at 12:45
p.m. on October 19, 2014.

* Fuel consumption of the models named above:
Audi TTS:
Combined fuel consumption in l/100 km: 7,5 - 6,9; Combined
CO2-emissions in g/km: 174 - 159
The fuel consumption and the CO2 emissions of a vehicle vary due to
the choice of wheels and tires. They not only depend on the
efficient utilization of the fuel by the vehicle, but are also
influenced by driving behavior and other non-technical factors.
