The race to create the first production self-driving car began in the early 2010s with many major automakers, including Ford, Audi, Nissan and Toyota, testing driverless systems. A major breakthrough was achieved in 2010, when Audi sent a driverless TT to the top of the Pikes Peak race course in 27 minutes with a top speed of 45 mph. While the numbers are far from overwhelming, the project was successful and proved autonomous cars can become a reality in the near future. Nearly four years later, Audi is back to showcase yet another self-driving car, the RS7 Piloted Driving Concept.

Based on the luxurious and fast RS7 sedan, this self-driving car is packed with the company’s latest technology in terms of orientation devices and on-board networking systems, and is set to debut at racing speed on Germany’s Hockenheimring track. Audi predicts top speeds of up to 149 mph and forces of up to 1.1g under acceleration, two enticing figures for a car that runs without a driver on board.

Visually, the Piloted Driving Concept is like any other 2014 Audi RS7, meaning the sedan is devoid of the mild refresh introduced for the 2015 model year, and sports the pre-facelift headlamps and taillights. Additionally two minor differences can be spotted. The most noticeable difference is the custom livery that features a monochrome design, the company’s logo and "Auto piloted driving" lettering on the doors. A closer look reveals the sedan no longer features chrome inserts, with blacked-out pieces replacing the grille frame and window trims.

Interior

The single photo showing the concept’s interior reveals the cabin remained largely unchanged, with only a few additional buttons and switches added to the center console. There may be more extra gear fitted in the cockpit to help Audi engineers monitor the self-driving car, but details are extremely limited as of this writing.

Drivetrain

Motivating the Piloted Driving Concept is the same twin-turbo, 4.0-liter V-8 engine found in the regular RS7. The unit cranks out 560 horsepower and 516 pound-feet of torque, exposing the self-driving sedan to the same outstanding performance figures that come with the production RS7. Specifically, the car will accelerate from naught to 60 mph in only 3.9 seconds before reaching a top speed of 189 mph. The powerful engine mates to an eight-speed automatic transmission and a quattro all-wheel-drive system.

Self-Driving Technology

Enabling the RS7 Piloted Driving Concept to drive itself around the track is a host of innovative technologies and an on-board networking system

Enabling the RS7 Piloted Driving Concept to drive itself around the track is a host of innovative technologies and an on-board networking system. Audi says the RS7 uses "specially corrected GPS signals" for orientation around the race course. The data, which is accurate down to one centimeter (0.4 inches), is combined with 3D camera images that are compared with graphical information stored on board. The data and images are compared in real time with patterns behind the track and the system returns even more precise information, helping the sedan position itself better on the route.

The on-board networking system controls everything from the power steering, braking and throttle valve to the automatic transmission and all-wheel-drive system in a process that has been tested over thousands of miles on a variety of routes. Audi expects the self-driving RS7 to perform at its physical limits and lap the Hockenheimring at full throttle on straights, full braking before the corners, precise turn-in and perfectly balanced acceleration when exiting the corners.

The car is predicted to lap the German track in two minutes and ten seconds, while reaching a top speed of 149 mph and forces over 1.3g under braking and up to 1.1g when accelerating. Quite impressive for a vehicle that runs without a driver on board.

The RS7 Piloted Driving Concept will remains just a study, as Audi’s main goal with it was to created the sportiest self-driving car yet. If the technology makes it to production, it will likely be used in a different kind of vehicle.

Meanwhile, there is a price to pay if you want to see this RS7 in action at the Hockenheim track. The sedan will lap the course on October 17th and October 19th, prior to the start of the DTM race. Friday tickets cost €10 ($12.77 as of 10/15/2014), while Sunday tickets start from €21 ($26.69) with advanced booking and from €25 ($31.93) on the day.

Several automakers are currently working on autonomous cars, including Renault, Ford, Nissan, Toyota, and Tesla Motors. The French company has already showcased a prototype in the form of the ZOE-based Next Two, and although it’s not as powerful as the RS7 Piloted Driving, it has what it takes to drive itself in traffic. The Next Two is still a long way from hitting the streets as a production car, but Renault claims it could be out by 2020.

The compact vehicle is fitted with a smart modem that connects automatically to the best available network and a multimedia platform compatible with all operating systems. Once the Next Two goes online, the driver is basically free to complete other tasks while the car is driving by itself.

Conclusion

Granted, a self-driving performance car would take all the fun out of driving a sporty and capable vehicle, but the technology comes with certain advantages when it comes to regular cars people might use on a daily basis. Studies claim people spend about two hours per day in their cars, which essentially means two hours of unproductive time. This could be reduced drastically if owners no longer need to drive their cars to work or anywhere else, resulting in more productive and enjoyable activities.

Of course, it will take a few more years before the self-driving car becomes a mainstream reality, but it’s nice to see automakers such as Audi making important progress in the performance department, even if restricted to the track.

Audi’s been at the forefront of autonomous driving, having developed a handful of driver-less models in past years. One that immediately comes to mind is the Autonomous Audi TT Pikes Peak, which made its debut in November 2010 to showcase what the car can do running up the famous Pikes Peak Hill Climb without a driver manning the wheel.

The project was actually made possible through a collaboration between Audi, Stanford University, the Volkswagen Group Electronics Research Lab in Palo Alto, California, and Oracle. More importantly, it successfully completed a full lap time going up Pikes Peak in 27 minutes, reaching a top speed of 45 mph.

The numbers itself weren’t overwhelming, but the goal wasn’t staggering numbers. The objective was to showcase the technology that allowed the car to drive up the treacherous hill autonomously, and it was successful in more ways than one.

The Autonomous TT Pikes Peak is just one example of Audi’s desire to be a leader in autonomous driving. In September 2014, Audi also became the first automaker to receive a permit in California to drive autonomous vehicles, making it the first and so far only one automaker to be allowed to engage in extensive testing of its autonomous vehicles on California’s roads.

Getting this permit is especially crucial for Audi because its own Electronics Research Laboratory is in Belmont, California, making it easy for the company to conduct its autonomous test runs close to its headquarters.

So when you happen to be driving along the 105 or the 210 and you happen to stumble upon an Audi without anybody behind the wheel, don’t think somebody’s playing a trick on you.

That’s Audi showing you what the future holds for autonomous driving.

Press Release

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.

2015 Audi RS7 Piloted Driving Concept High Resolution Exterior

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.

Press material has been compiled in a digital press folder (www.audi-mediaservices.de/presskit/en/piloted_driving_2014).

Piloted driving – highlights
Audi has been working intensively on the subject of “piloted driving” for many years now. The development efforts have produced numerous spectacular driving feats – on public roads, on the race track and even on a salt bed.

2009: Bonneville Salt Flats
In fall 2009, Audi took to the Bonneville Salt Flats in Utah, USA, with a driverless Audi TTS. Driving in precise curves, the white coupe carved the brand’s four rings into the salt bed. It also set a new speed record for piloted driving cars of 130 mph (approx. 210 km/h).

As homage to former Audi rally driver Michèle Mouton, the technology platform was dubbed “Shelley.” Its specific data technology was developed jointly by Audi, Volkswagen and the Center for Automotive Research at Stanford University in California.

2010: Pikes Peak
The next year, the piloted driving “Shelley” conquered the legendary Pikes Peak mountain race circuit in Colorado, USA. The technology platform covered the 20 kilometer (12.4 mi) course with a total of 156 corners in roughly 27 minutes, reaching a top speed of 45 mph (72 km/h). Navigation was already via differential GPS and accurate to just a few centimeters.

2012: Thunderhill Race Track
In 2012, Audi garnered its initial experience with the Audi TTS on a race track – the Thunderhill Race Track north of Sacramento, California. The lap time on the roughly three-mile (nearly five kilometers) course was under 2 minutes and 30 seconds. The tests were focused on how a piloted driving car behaves at high loads and under extreme conditions.

2013: Las Vegas
The authorities in the US state of Nevada made the Audi the world’s first automobile maker to receive a permit to operate piloted driving cars in public traffic. In January 2013 and 2014, the brand presented new systems for piloted driving in traffic jams and for piloted parking at the International Consumer Electronics Show (CES) in Las Vegas. International trade journalists were on board both times.

2014: Florida and California
Audi is rapidly expanding its testing competence for piloted driving in the USA. This summer, the brand was once again the world’s first automobile maker to conduct a public test on the Lee Roy Selmon Expressway outside Tampa, Florida. The company this fall received the first test license under the new regulations in California, where test drives on the freeways are now generally permitted.

Piloted driving – future production technology
The production technologies for piloted driving currently under development at Audi will make their way into cars before the end of this decade. The new systems will then take over the driving in certain situations, such as in traffic jams or when parking, making it even more convenient and safe.

Piloted driving in traffic jams
In the future, the “traffic jam pilot” will help Audi drivers by taking over the steering at speeds between 0 and 60 km/h (37.3 mph) in addition to accelerating and braking automatically.

To do this, the new system assesses the status of the car as well as the entire surroundings. If the customer activates the system, the car completely takes over longitudinal and lateral guidance when it detects a traffic jam on a highway at speeds between 0 and 60 km/h (37.3 mph).

When the traffic jam pilot reaches its limits, such as when the traffic jam dissolves or the end of a divided road is reached, it prompts the driver to take over the wheel again.

A key component of the system of sensors is the radar system. As with today’s adaptive cruise control with stop & go function, it monitors a 35-degree field in front of the car at a range of up to 250 meters (820.2 ft). A video camera with a wide angle of aperture detects the lane markings as well as pedestrians and objects, such as other vehicles and guard rails. Up to twelve ultrasonic sensors are used to monitor the immediate space around the car.

A new member of the sensor portfolio is the laser scanner, which delivers highly precise data at a distance of up to 80 meters (262.5 ft). Its laser diode emits nearly 100,000 infrared light pulses per second that are invisible to the human eye. The laser scanner covers a 145-degree field on six levels. The controller computes a surroundings profile from the light reflections that shows both other vehicles and guard rails.

The laser scanner offers key advantages. Because of its wide angle of aperture, it detects cars entering the lane very early and also remains fully functional in the dark. It can detect all types of objects, including those with a homogeneous pattern, such as fences, or with no visible structure, such as white walls.

Piloted driving for parking maneuvers
Parking maneuvers in tight situations are unpleasant – narrow parking spaces or garages make it difficult for the driver to get in and out of the car. With the “parking pilot” system from Audi, drivers can get out and control the car remotely using the remote key fob or a smartphone. This system uses the same sensor systems as the traffic jam pilot, but also uses its four 360° cameras to generate additional key information about its surroundings.

2015 Audi RS7 Piloted Driving Concept High Resolution Exterior

The parking pilot offers the piloted parking function to the driver when the environmental sensors detect a suitable parking space or garage. If the driver gets out of the car, he or she needs only to press the key fob or the corresponding button on their smartphone to initiate the process.

The system checks to make sure that the key is in the vicinity of the car. If the on-board sensors detect obstacles in the driving corridor during piloted parking, the car stops immediately. When the car arrives at its parking position, the system turns off the engine and locks the doors. The driver receives a confirmation message. The push of a button is likewise all that is required to retrieve the car from the garage or parking space.

The central driver assistance control unit (zFAS)
Today’s driver assistance systems are usually managed by spatially separated control units. Audi, in contrast, is taking the novel approach of a central domain architecture. In the future, all available sensor information will flow into a central control unit (zFAS). This computes a complete model of the vehicle surroundings that is used by all of the assistance systems. The future systems for piloted driving will also draw on this redundantly computed information.

The central driver assistance control board uses cutting-edge multi-core processors. All together, they have the computing power of the entire electronics architecture of today’s Audi A4*. The new board currently has about the same area as a tablet PC, but its space requirements will continue to shrink. Its modular concept ensures high scalability and future viability. Audi will be introducing the central driver assistance control module to production along with the systems for piloted driving by the end of this decade.

Relaxed and under control– today’s driver assistance systems
Audi already offers numerous driver assistance systems to make driving more relaxed and under control. No need is left uncovered, and the full capabilities of these systems are on display in the updated Audi A6* and Audi A7 Sportback* model series.

Adaptive cruise control with stop & go function
Of all the optional driver assistance systems offered by Audi, adaptive cruise control with stop & go function including Audi pre sense front is the most complex. It regulates the speed and the distance to the vehicle ahead by accelerating and braking in a range from 0 to 250 km/h (155.3 mph), and brakes automatically within certain limits. The driver can use Audi drive select to switch between four settings to specify just how comfortable or sporty the system should be.

The ACC stop & go function uses data from two radar sensors, a video camera, ultrasound sensors and additional systems. In addition, it uses predictive route data from the navigation system to reliably calculate the proper line on the highway, even in curves. In city traffic, the ACC stop & go automatically slows the car to a stop.

Audi side assist
Audi side assist including Audi pre sense rear is activated at 30 km/h (18.6 mph). Two radar sensors at the rear of the car monitor what goes on behind it. If the system detects another vehicle moving into the critical zone from behind, a yellow LED display lights up in the housing of the exterior mirror. If the driver nevertheless activates the turn signal to change lanes, the indicator becomes brighter and begins to flash quickly – a signal that is hard to miss.

Audi active lane assist
Audi active lane assist employs a video camera to detect lane markings at speeds above 65 km/h (40.4 mph). If the car approaches a line without the turn signal being activated, the system helps the driver to steer back into the lane by intervening gently in the electromechanical power steering. Drivers use the MMI to specify how quickly this assistance system should intervene and whether the steering wheel should vibrate as well. If the driver selects early intervention, the system also helps to keep the car in the center of the lane.

In the new Audi A6 and A7 Sportback models, Audi active lane assist works closely together with Audi side assist. If both are activated, the warning before a critical lane change is accompanied by targeted intervention in the steering.

Camera-based speed limit display
The camera-based speed limit display recognizes speed limit signs on the side of the road, their supplemental signs and the signs canceling speed limits. It presents these as graphics on the display of the driver information system or on the optional head-up display. Software compares images supplied by the video camera with map data from the optional MMI navigation plus.

Night vision assistant
Another high-end feature is the night vision assistant. Its thermal imaging camera uses far infrared technology to “see” up to 300 meters (984.3 ft) ahead. Data is converted into black-and-white images that are displayed on the large driver information system screen. People and animals appear conspicuously bright on the screen due to the heat they give off, whereas the surroundings appear dark. The software can detect people and large animals and highlights them in the display in yellow.

2015 Audi RS7 Piloted Driving Concept High Resolution Exterior

If the computer anticipates a hazardous situation, the brake system is automatically prefilled. A warning signal sounds and a red warning also appears on the driver information system’s screen and in the optional head-up display. If the car is equipped with the high-beam assistant or Matrix LED headlights, persons detected outside of town limits are illuminated with three short flashes of light.

Park assist with 360° display
Audi offers various options that make parking easy. The park assist system with 360° display uses ultrasonic sensors to locate and measure parking spaces along the side of the road at low vehicle speeds. If a sufficiently large space is found, the system takes over parallel parking at the push of a button. The driver has to apply the gas and brake.

The park assist system can maneuver the car into a space either parallel or perpendicular to the road. In addition, a 360° display warns of obstacles to the sides. Front-mounted and reversing cameras are also available.

Audi pre sense
The Audi pre sense safety system is available in a number of different versions. In the standard version – Audi pre sense basic – the system intervenes immediately upon detecting an unstable driving situation via the ESC sensors. The front seat belts are electrically tensioned and the sunroof and the side windows are closed, leaving just a small gap. The vehicle’s hazard warning lights will warn the traffic behind.

The Audi pre sense front version is available in combination with ACC stop & go. This system is intended to prevent rear-end collisions – or at least reduce the consequences of such accidents. The integrated Audi braking guard is activated in a dangerous situation to warn the driver, first with an acoustic signal and a visual signal. At the same time, the brake system is prefilled and the dampers of the optional adaptive air suspension are also set to hard.

If the driver still does not react, then the system briefly brakes the vehicle – a jolt which serves as the second warning; the belts are slightly pretensioned. If the driver depresses the brake pedal now, the hydraulic brake assist increases braking power as appropriate for the situation. Should the driver ignore the warning jolt, autonomous partial braking will be initiated – provided that the vehicle ahead is in motion Deceleration is at a rate of 3.5 m/s2. The windows and sunroof will be closed, seat belts tensioned considerably, and hazard warning lights activated.

2015 Audi RS7 Piloted Driving Concept High Resolution Exterior

If the car is equipped with the full version of Audi pre sense – Audi pre sense plus – a third and a fourth stage follow in the event of an emergency. The system will then increase deceleration initially to 6 m/s² and tighten the belts completely. The last braking phase – the autonomous full brake application – occurs roughly half a second before an inevitable collision. The consequences of such a collision can thus be greatly reduced.

At speeds below 30 km/h (18.6 mph), the car will brake autonomously with full force in an emergency – regardless of whether the car in front is moving or standing still. Below 20 km/h (12.4 mph), this full braking frequently prevents the accident altogether or greatly reduces the impact speed.

Immediately after a collision, the secondary collision brake assist helps the driver by initiating braking automatically. This reduces the risk of skidding and additional collisions during the course of the accident.

Yet another Audi pre sense subfunction, Audi pre sense rear, is coupled with Audi side assist. If the system detects an imminent rear-end collision, it uses the adaptive brake light to warn the traffic behind.
