“We are dire brazen with one of a many vicious trends in a automotive universe with a technical solutions for piloted driving,” says Prof. Dr. Ulrich Hackenberg, Board Member for Technical Development during AUDI AG. “The finish mindfulness of this growth will be put on arrangement during a DTM competition in Hockenheim. A path time of customarily over dual mins and together acceleration of adult to 1.1 g pronounce for themselves.”
Audi has prolonged been a pushing force in a area of rarely programmed driving. The brand’s growth efforts have constructed a array of fantastic feats. In 2010, for instance, a driverless Audi TTS* cowed a mythological Pikes Peak towering competition circuit in Colorado, USA. Audi has time and again showcased a intensity of a record with demonstrations during a limit. With 560 hp and a tip speed of 305 km/h (189.5 mph), a Audi RS 7 piloted pushing judgment automobile exemplifies Vorsprung durch Technik.
The Audi RS 7 piloted pushing judgment automobile on a competition track
The Audi RS 7 piloted pushing judgment automobile is a record height with that Audi is exploring a possibilities of piloted pushing during a many dynamic. On Friday, Oct 17 and Sunday, Oct 19 – before to a start of a final DTM competition – a judgment automobile will finish one path on a Hockenheim ring though a driver. The large, five-door coupe is mostly matching to a prolongation model, though a electromechanical energy steering, a brakes, a stifle valve and a eight-speed tiptronic that distributes a energy to a involuntary quattro expostulate complement are tranquil automatically.
There are dual primary technological considerations during piloted pushing during a earthy limit: a rarely accurate march of a automobile on a highway and comprehensive control of a automobile during a doing limits.
The record height uses specifically corrected GPS signals for march on a track. Accurate down to a centimeter, these differential GPS information are transmitted to a automobile around WLAN according to a automotive customary and redundantly around high-frequency radio. Parallel to this, 3D camera images are compared in genuine time opposite graphical information stored on board. The complement searches in any of a vast particular images for several hundred famous features, such as building patterns behind a track, that it afterwards uses as additional positioning information.
Control of a automobile during a doing boundary is another superb underline of a Audi RS 7 piloted pushing judgment car. Comprehensive on-board networking joined with a rarely accurate control of all actors applicable to pushing capacitate a record height to expostulate during a earthy limits. The Audi engineers intensively investigated piloted pushing during a doing limits, putting a record height by several thousand exam kilometers on a accumulation of routes.
To denote a capabilities, a Audi RS 7 piloted pushing judgment automobile will expostulate a purify racing line during a Hockenheimring – with full stifle on a straights, full braking before a corners, accurate turn-in and ideally metered acceleration when exiting a corners. Forces of over 1.3 g start during braking, and together acceleration in a corners can strech 1.1 g. Tests on a line in Hockenheim suggested an approaching tip speed of 240 km/h (149.1 mph) and a path time of 2 mins and 10 seconds.
The competition line is also a many perfectionist exam bed for prolongation when it comes to piloted driving. The destiny systems contingency also work intensely precisely and with 0 errors in vicious situations. They therefore contingency be able of scrupulously assessing a tide conditions even during a earthy limit. This exam bed provides a Audi engineers with a accumulation of insights for prolongation development, such as for a growth of involuntary deterrence functions in vicious pushing situations.
The path by a RS 7 piloted pushing judgment automobile can be followed around live tide (www.audimedia.tv/en). The promote starts during 12:45 p.m. on Oct 19, 2014.
Press element has been gathered in a digital press folder (www.audi-mediaservices.de/presskit/en/piloted_driving_2014).
Piloted pushing – highlights
Audi has been operative intensively on a theme of “piloted driving” for many years now. The growth efforts have constructed countless fantastic pushing feats – on open roads, on a competition line and even on a salt bed.
2009: Bonneville Salt Flats
In tumble 2009, Audi took to a Bonneville Salt Flats in Utah, USA, with a driverless Audi TTS. Driving in accurate curves, a white coupe forged a brand’s 4 rings into a salt bed. It also set a new speed record for piloted pushing cars of 130 mph (approx. 210 km/h).
As loyalty to former Audi convene motorist Michèle Mouton, a record height was dubbed “Shelley.” Its specific information record was grown jointly by Audi, Volkswagen and a Center for Automotive Research during Stanford University in California.
2010: Pikes Peak
The subsequent year, a piloted pushing “Shelley” cowed a mythological Pikes Peak towering competition circuit in Colorado, USA. The record height lonesome a 20 kilometer (12.4 mi) march with a sum of 156 corners in roughly 27 minutes, reaching a tip speed of 45 mph (72 km/h). Navigation was already around differential GPS and accurate to customarily a few centimeters.
2012: Thunderhill Race Track
In 2012, Audi garnered a initial knowledge with a Audi TTS on a competition line – a Thunderhill Race Track north of Sacramento, California. The path time on a roughly three-mile (nearly 5 kilometers) march was underneath 2 mins and 30 seconds. The tests were focused on how a piloted pushing automobile behaves during high loads and underneath impassioned conditions.
2013: Las Vegas
The authorities in a US state of Nevada done a Audi a world’s initial automobile builder to accept a assent to work piloted pushing cars in open traffic. In Jan 2013 and 2014, a code presented new systems for piloted pushing in trade jams and for piloted parking during a International Consumer Electronics Show (CES) in Las Vegas. International trade reporters were on house both times.
2014: Florida and California
Audi is fast expanding a contrariety cunning for piloted pushing in a USA. This summer, a code was once again a world’s initial automobile builder to control a open exam on a Lee Roy Selmon Expressway outward Tampa, Florida. The association this tumble perceived a initial exam permit underneath a new regulations in California, where exam drives on a freeways are now generally permitted.
Piloted pushing – destiny prolongation technology
The prolongation technologies for piloted pushing now underneath growth during Audi will make their proceed into cars before a finish of this decade. The new systems will afterwards take over a pushing in certain situations, such as in trade jams or when parking, creation it even some-more accessible and safe.
Piloted pushing in trade jams
In a future, a “traffic jam pilot” will assistance Audi drivers by holding over a steering during speeds between 0 and 60 km/h (37.3 mph) in further to accelerating and braking automatically.
To do this, a new complement assesses a station of a automobile as good as a whole surroundings. If a patron activates a system, a automobile totally takes over longitudinal and together superintendence when it detects a trade jam on a highway during speeds between 0 and 60 km/h (37.3 mph).
When a trade jam commander reaches a limits, such as when a trade jam dissolves or a finish of a divided highway is reached, it prompts a motorist to take over a circle again.
A pivotal member of a complement of sensors is a radar system. As with today’s adaptive journey control with stop go function, it monitors a 35-degree margin in front of a automobile during a operation of adult to 250 meters (820.2 ft). A video camera with a far-reaching angle of orifice detects a line markings as good as pedestrians and objects, such as other vehicles and ensure rails. Up to twelve ultrasonic sensors are used to ensure a evident space around a car.
A new member of a sensor portfolio is a laser scanner, that delivers rarely accurate information during a stretch of adult to 80 meters (262.5 ft). Its laser diode emits scarcely 100,000 infrared light pulses per second that are invisible to a tellurian eye. The laser scanner covers a 145-degree margin on 6 levels. The controller computes a closeness form from a light reflections that shows both other vehicles and ensure rails.
The laser scanner offers pivotal advantages. Because of a far-reaching angle of aperture, it detects cars entering a line really early and also stays entirely organic in a dark. It can detect all forms of objects, including those with a comparable pattern, such as fences, or with no manifest structure, such as white walls.
Piloted pushing for parking maneuvers
Parking maneuvers in parsimonious situations are upsetting – slight parking spaces or garages make it formidable for a motorist to get in and out of a car. With a “parking pilot” complement from Audi, drivers can get out and control a automobile remotely regulating a remote pivotal fob or a smartphone. This complement uses a same sensor systems as a trade jam pilot, though also uses a 4 360° cameras to beget additional pivotal information about a surroundings.
The parking commander offers a piloted parking duty to a motorist when a environmental sensors detect a suitable parking space or garage. If a motorist gets out of a car, he or she needs customarily to press a pivotal fob or a analogous symbol on their smartphone to trigger a process.
The complement checks to make certain that a pivotal is in a closeness of a car. If a on-board sensors detect obstacles in a pushing mezzanine during piloted parking, a automobile stops immediately. When a automobile arrives during a parking position, a complement turns off a engine and thatch a doors. The motorist receives a acknowledgment message. The pull of a symbol is further all that is compulsory to collect a automobile from a garage or parking space.
The executive motorist assistance control section (zFAS)
Today’s motorist assistance systems are customarily managed by spatially distant control units. Audi, in contrast, is holding a novel proceed of a executive domain architecture. In a future, all accessible sensor information will upsurge into a executive control section (zFAS). This computes a finish indication of a automobile closeness that is used by all of a assistance systems. The destiny systems for piloted pushing will also pull on this redundantly computed information.
The executive motorist assistance control house uses cutting-edge multi-core processors. All together, they have a computing energy of a whole wiring design of today’s Audi A4*. The new house now has about a same area as a inscription PC, though a space mandate will continue to shrink. Its modular judgment ensures high scalability and destiny viability. Audi will be introducing a executive motorist assistance control procedure to prolongation along with a systems for piloted pushing by a finish of this decade.
Relaxed and underneath control– today’s motorist assistance systems
Audi already offers countless motorist assistance systems to make pushing some-more loose and underneath control. No need is left uncovered, and a full capabilities of these systems are on arrangement in a updated Audi A6* and Audi A7 Sportback* indication series.
Adaptive journey control with stop go function
Of all a discretionary motorist assistance systems offering by Audi, adaptive journey control with stop go duty including Audi pre clarity front is a many complex. It regulates a speed and a stretch to a automobile forward by accelerating and braking in a operation from 0 to 250 km/h (155.3 mph), and brakes automatically within certain limits. The motorist can use Audi expostulate name to switch between 4 settings to mention customarily how gentle or sporty a complement should be.
The ACC stop go duty uses information from dual radar sensors, a video camera, ultrasound sensors and additional systems. In addition, it uses predictive track information from a navigation complement to reliably calculate a correct line on a highway, even in curves. In city traffic, a ACC stop go automatically slows a automobile to a stop.
Audi side assist
Audi side support including Audi pre clarity behind is activated during 30 km/h (18.6 mph). Two radar sensors during a behind of a automobile ensure what goes on behind it. If a complement detects another automobile relocating into a vicious section from behind, a yellow LED arrangement lights adult in a housing of a extraneous mirror. If a motorist though activates a spin vigilance to change lanes, a indicator becomes brighter and starts to peep fast – a vigilance that is tough to miss.
Audi active line assist
Audi active line support employs a video camera to detect line markings during speeds above 65 km/h (40.4 mph). If a automobile approaches a line though a spin vigilance being activated, a complement helps a motorist to drive behind into a line by inserted kindly in a electromechanical energy steering. Drivers use a MMI to mention how fast this assistance complement should meddle and possibly a steering circle should quiver as well. If a motorist selects early intervention, a complement also helps to keep a automobile in a core of a lane.
In a new Audi A6 and A7 Sportback models, Audi active line support works closely together with Audi side assist. If both are activated, a warning before a vicious line change is accompanied by targeted involvement in a steering.
Camera-based speed extent display
The camera-based speed extent arrangement recognizes speed extent signs on a side of a road, their supplemental signs and a signs canceling speed limits. It presents these as graphics on a arrangement of a motorist information complement or on a discretionary head-up display. Software compares images granted by a video camera with map information from a discretionary MMI navigation plus.
Night prophesy assistant
Another high-end underline is a night prophesy assistant. Its thermal imaging camera uses distant infrared record to “see” adult to 300 meters (984.3 ft) ahead. Data is converted into black-and-white images that are displayed on a vast motorist information complement screen. People and animals seem conspicuously splendid on a shade due to a feverishness they give off, since a closeness seem dark. The program can detect people and vast animals and highlights them in a arrangement in yellow.
If a mechanism anticipates a dangerous situation, a stop complement is automatically prefilled. A warning vigilance sounds and a red warning also appears on a motorist information system’s shade and in a discretionary head-up display. If a automobile is versed with a high-beam partner or Matrix LED headlights, persons rescued outward of city boundary are bright with 3 brief flashes of light.
Park support with 360° display
Audi offers several options that make parking easy. The park support complement with 360° arrangement uses ultrasonic sensors to locate and magnitude parking spaces along a side of a highway during low automobile speeds. If a amply vast space is found, a complement takes over together parking during a pull of a button. The motorist has to request a gas and brake.
The park support complement can scheme a automobile into a space possibly together or perpendicular to a road. In addition, a 360° arrangement warns of obstacles to a sides. Front-mounted and reversing cameras are also available.
Audi pre sense
The Audi pre clarity reserve complement is accessible in a array of opposite versions. In a customary chronicle – Audi pre clarity simple – a complement intervenes immediately on detecting an inconstant pushing conditions around a ESC sensors. The front chair belts are electrically tensioned and a sunroof and a side windows are closed, withdrawal customarily a tiny gap. The vehicle’s jeopardy warning lights will advise a trade behind.
The Audi pre clarity front chronicle is accessible in multiple with ACC stop go. This complement is dictated to forestall rear-end collisions – or during slightest revoke a consequences of such accidents. The integrated Audi braking ensure is activated in a dangerous conditions to advise a driver, initial with an acoustic vigilance and a visible signal. At a same time, a stop complement is prefilled and a dampers of a discretionary adaptive atmosphere cessation are also set to hard.
If a motorist still does not react, afterwards a complement quickly brakes a automobile – a jar that serves as a second warning; a belts are somewhat pretensioned. If a motorist depresses a stop pedal now, a hydraulic stop support increases braking energy as suitable for a situation. Should a motorist omit a warning jolt, unconstrained prejudiced braking will be instituted – supposing that a automobile forward is in suit Deceleration is during a rate of 3.5 m/s2. The windows and sunroof will be closed, chair belts tensioned considerably, and jeopardy warning lights activated.
If a automobile is versed with a full chronicle of Audi pre clarity – Audi pre clarity and – a third and a fourth theatre follow in a eventuality of an emergency. The complement will afterwards boost deceleration primarily to 6 m/s² and tie a belts completely. The final braking proviso – a unconstrained full stop focus – occurs roughly half a second before an unavoidable collision. The consequences of such a collision can so be severely reduced.
At speeds next 30 km/h (18.6 mph), a automobile will stop autonomously with full force in an puncture – regardless of possibly a automobile in front is relocating or station still. Below 20 km/h (12.4 mph), this full braking frequently prevents a collision altogether or severely reduces a impact speed.
Immediately after a collision, a delegate collision stop support helps a motorist by initiating braking automatically. This reduces a risk of skidding and additional collisions during a march of a accident.
Yet another Audi pre clarity subfunction, Audi pre clarity rear, is joined with Audi side assist. If a complement detects an approaching rear-end collision, it uses a adaptive stop light to advise a trade behind.
