Audi-A7-Sportback-Silicon-Valley-to-Las-Vegas

The long-distance test drive with the Audi A7 piloted driving concept concluded successfully following its 560-mile (approximately 900 kilometres) journey. A selected group of journalists were able to experience piloted driving from behind the wheel during the drive that began in Silicon Valley, California and ended in Las Vegas, Nevada in time to attend the International CES 2015 (Consumer Electronics Show).
 
The concept vehicle impressed particularly through its ability to provide a comfortable drive in rear world, everyday driving situations. 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 Ulrich Hackenberg, Audi Board Member for Technical Development. "I‘d like to thank the team of Audi engineers, VW Group R&D 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 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 A7 piloted driving concept utilizes the latest technologically advanced systems developed by Audi. The concept relieves the driver of driving duties from 0 to 70 mph, or just over 110 kmph. The car, that has been affectionately been named ‘Jack’ by the development team, can initiate lane changes and passing maneuvers. In addition, the A7 piloted driving concept accelerates and brakes independently.

Before initiating a lane change to the left or the right, 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.

 

The piloted concept vehicle utilizes a combination of various sensors, many of which are close to production ready. The long range radar sensors of the adaptive cruise control (ACC) and the Audi side assist (ASA) keep watch of the front and rear of the vehicle. Two mid-range radar sensors at the front and rear respectively are aimed to the right and left to complete the 360 degree view.

 

Laser scanners are mounted within the Singleframe grille and the rear bumper skirt. The scanners deliver redundant information to provide detailed recognition of static and dynamic objects during piloted driving. The technologies are production ready including their vehicle integration and cost structure for vehicle production in the near future. A new hi-resolution 3D video camera, already integrated into the next generation systems found in the new Q7, takes a wide-angle view out in front of the vehicle. Four small front and rear mounted cameras view closer surroundings.

 

Navigation data is used for basic vehicle orientation. 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 signals 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 an acoustic warning indicator requires the driver to retake control. Should the driver ignore the signals, the system activates the hazard lights and brings the car to a full stop while minimizing any risk. In most instances the vehicle is stopped on the right emergency lane.
