Audi will demonstrate the capabilities of its autonomous driving technology between Silicon Valley and Las Vegas.
The German automaker said it is demonstrating that the era of automated driving is nearly here by having one of its cars cover more than 550 miles of piloted highway driving with journalists behind the wheel,.
The long-distance test drive of the Audi A7 piloted driving concept car will show, according to Audi, that unprecedented performance can be achieved with series production technology.
The drive will take place from Silicon Valley, California to Las Vegas, Nevada to attend the International CES 2015 (Consumer Electronics Show).
“The test drive from the west coast of California to Las Vegas demonstrates our leadership role in piloted driving,” said Prof. Dr. Ulrich Hackenberg, Audi Board Member and Head of Technical Development. “The test drive in real world traffic and road conditions represents a joint effort by the Volkswagen Electronics Research Laboratory (ERL) und Volkswagen Group Research and Development, begins today (January 4) in Stanford, Calif.”
Audi added 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 km/h. 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, explained Audi. 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 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, stated Audi, 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 said to be used for basic vehicle orientation.
Before the piloted driving system reaches its limits, in city environments for example, the driver is requested to take control of the vehicle to ensure proper safety, added Audi. 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 a acoustic warning indicator requires the driver to retake control.
Security is at the top of Audi’s engineer’s minds. Should the driver ignore the signals, said Audi, 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.
Audi stated each journalist will drive approximately 100 miles utilizing the piloted driving system. A trained Audi professional test driver will accompany the media from the passenger seat for added safety.
Audi will present its “Next Chapter” at CES between January 6 through 9, 2015 in Las Vegas. The company said its primary topic will be the connected car with its surroundings. Piloted driving, new user and display interfaces, modern infotainment and new Audi connect solutions, as well as LED and laser-matrix lighting technologies will be presented; Audi also said as part of the world premieres, a show car and the interior model of the new Audi Q7 will be shown.
