The Audi A7 3.0 TFSI quattro piloted driving concept proved itself very cabable of driving in traffic just as customers do on a daily basis. Journalists that were behind the wheel were impressed with the concept cars ability to drive comfortably and in the logical user interface for which Audi is known. „The results of the test drive underscores our piloted driving competency“, said Prof. Dr. Ulrich Hackenberg, Audi Board Member for Technical Development. „I‘d like to thank the team of Audi engineers, VW Group RD and the Electronics Research Laboratory for making it such a great success.“
The test drive resulted in actionable data to help further development of Audi piloted driving. Even so it offered the longest drive at full highway speeds with members of the public behind the wheel. The journalists were able to experience piloted driving in 100 mile stints in various traffic situations on public highways . In total, the the drive was 560 miles long, or approximately 900 kilometers. As required by State laws in California, an experienced Audi test driver accompanied the drive from the passenger seat.
The concept vehicle utilizes various production-ready sensors as well as sensors integrated into production vehicles today that accurately detect the vehicles surroundings.Adaptive cruise control (ACC) and Audi side assist (ASA) long-range radar sensors as well as mid-range radar sensors at the front and the rear of the vehicle that are directed to the left and right of the vehicle provide the vehicle with a 360 degree view of its environment. Laser scanners are integrated into the front Singleframe grille as well the rear bumper to provide additional detailed recognition of static or dynamic objects. The redundance of the sensor data constists of a continuous plausibility check during piloted driving to ensure the correct decisions are being made the vehicle and the driver. Four smaller cameras at the front and rear of the vehicle provide short-range information of the surrounding environment. The hi-resolution, wide-angle 3D video camera, which will first see production in the the new Audi Q7, obvserves the surrounding traffic surrounding the vehicle. The sensors utilizes is close to production and meets financial targets for inclusion into future products.
The concept relieves the driver of driving duties from 0 to 70 mph, or just over 110 km/h. The car can initiate lane changes and passing maneuvers as well as accelerate and brake independently. Before initiating a lane change to the left or the right (on US highways), the vehicle adapts its speed to surrounding vehicles. If the speed and distance calculation is deemed safe, the vehicle initiates the lane change with precision and in a timely manner.
Before the piloted driving system reaches its limitations, in city environments for example, the driver is requested to take control of the vehicle to ensure proper safety. Multiple warning signales work in unison: colored LEDs at the base of the windshield, signals in the driver information display, a Central Status Indicator (CSI), as well as a acoustic warning indicator requires the driver to retake control.
Audi will present its “Next Chapter” at CES from January 6th through 9th, 2015 in Las Vegas. The technologies of today and the projects of tomorrow will be presented at one of the most relevant, trendsetting electronic trade shows in the world. A multitude of technologies and two world premieres including the interior model of the new Q7 and another concept car will demonstrate the technological competencies of Audi. Primary topics will include new user and display interfaces, modern infotainment and new Audi connect solutions, as well as LED and laser-matrix lighting technologies will be presented. These and additional highlights of piloted driving will be shown. At the center of all of these topics is the car and its communication with its surroundings.
Audi MediaTV is broadcasting live from the International CES 2015 and is covering the Audi Press Conference on Tuesday, January 6, 2015 from 11:00 a.m. (Pacific Standard Time) / 8:00 p.m. (CET) in its entirety.
*Fuel consumption of the models named above:
Audi Q7:
Combined fuel consumption in l/100 km: 10.7 – 7.2** (22.0 – 32.7 US mpg);
Combined CO2 emissions in g/km: 249 – 189** (400.7 – 304.2 g/mi)
**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.
