Daytime running lights that consistof white light-emitting diodes are asafety and design feature thatreflects Audi‘s frontrunner roleamong the competition. Theymade their debut in the Audi A8W12 in 2004. This was the first step towardsgiving an Audi a unique andunmistakable headlight design.Meanwhile, the LED daytime run-ning lights are now offered in all ofthe brand‘s model series. In eachmodel, the light-intense diodesoffer many new degrees of free-dom in designing the inner life ofthe headlight. Whether its lines arecurved or straight, a model seriesfrom Audi is unmistakably linkedto a specific type of lighting. In the A1, two light-emittingdiodes are used per unit; they emittheir light into a transparent poly-mer tube, the light guide, whichgenerates a uniform contour. In theAudi A7 Sportback, the daytimerunning lights of the optional LEDheadlights also appear linear, butthey originate from 18 individualLEDs with a polymer body in front

of them. The LED daytime run-ning lights consume fewer watts ofpower, have extremely long lifeand are maintenance-free. The introduction of full-LEDheadlights to the A6, A7 Sport-back, A8 and most recently to theA3 model series , gives the carsunmistakable styling and a resolutelook. The small LEDs can bearranged in lines, and they variouslighting functions can be imple-mented by individually controllingthe diodes. The headlights gene-rate a light pattern that is unmistak-

able and in many cases achievesthree-dimensional effects. Suchimpressive design features couldonly be realized by close coopera-tion between engineers and de-signers. Stephan Berlitz, Head ofDevelopment for Lighting Func-tions/Innovations at Audi, says:„We always find a way to perfectlyharmonize technology and styling.“Cesar Muntada Roura of AudiExterior Design explains: „It is ourunderstanding of one another‘sareas of competence that make usso strong.“

• Audi further extends its lead in lighting technology • Close cooperation between engineers and designers • Innovative matrix LED headlights make their debut in 2013

In lighting technology, Audi is driving progress at high tempo. Today, its xenon plus-and LED head-

lights already provide excellent illumination of the road and give the cars with the four rings an

unmistakable look. In the future, vehicle lighting from Audi will react even more precisely to environ-

mental conditions, and it will feature full electronic control. The first step in this direction will be

taken this year in the form of innovative matrix LED headlights.

last the life of the vehicle, and arehighly efficient. The low-beamlight, for example, only consumesaround 40 watts, which is five per-cent less than xenon plus units. In the new A3, nine high-perfor-mance LED chips in two free-formreflectors generate the low-beamlight, while the high beam uses tenhigh-performance LEDs to emitlight through an aluminum trimaperture. The static turning and all-weather lights are housed in a sepa-rate module; while the daytimerunning lights, parking and flasherlights are formed by a light guidethat wraps around the upper andinner headlights as a narrow con-tour. The „wing“ gives structure tothe interior of the headlights. LED headlights from Audi havenot only proved themselves onthe streets, but also in car racing.They made their debut in the R15 TDI Le Mans sport protoypein 2010. In 2011, full-LED head-lights were installed for the firsttime in the next generation racecar, the R18 TDI.With their combined lightingpower of over 200 watts, the LEDsgenerate a light pattern with a rangeof over one kilometer. Their equi-valent luminous intensity of over1,000 lux is five to seven timesgreater than headlights in produc-

burner generates both the lowand high beam lights, and they areswitched by a moveable shutter.Of course, all xenon headlightsare mercury-free.

Audi is also far ahead of the com-petition in the area of LED head-lights. This high-end technologywas introduced in the R8 in 2008,and today it is being implementedall the way to the A3 model series.With a color temperature of around5,500 Kelvin, the LED light resemb-les daylight, and this reduces eyefatigue. The light-emitting diodesare maintenance-free, designed to

Lighting technology

Whether xenon plus or LED –the headlights and taillights inAudi models make a strong state-ment. The brand‘s lighting tech-nologies combine their attractiveeffects with a high level of activesafety – with adaptive light,today‘s headlights already react tothe environment and to othervehicles in traffic.

Xenon plus headlights are offeredin all models of the Audi lineup,either as optional or standardequipment. Xenon headlights aregas discharge lamps. Two tungs-ten electrodes are fused in aquartz glass cylinder, known asthe burner, and a concentratedlight arc burns between. Thexenon inert gas charge in the bur-ner, which is pressurized up to100 bar, gives off a slightly violetlight, while metallic salts in theglass cylinder charge reduce itscolor temperature to the spectrumof daylight. Xenon headlights provide a muchbrighter light and better illumina-tion than halogen headlights withincandescent bulbs, their energyconsumption is about 20 percent lower and they havemuch longer life. In xenon plustechnology from Audi, a single

tion cars. For many years now,LED technology has also been uti-lized in taillights – as standard oroptional equipment. Unlike incan-descent light sources, the light-emitting diodes reach full luminousintensity at lightning speed andwithout delay – when the driverbrakes quickly, for example, thequick reacting brake lights give thedriver of the vehicle behind addi-tional valuable fractions of a secondin reaction time.

Various adaptive light versions areavailable for the headlightsystems. An electronic controlmodule controls the swivelingxenon plus modules, or the LEDs,so that they always deliver thebest possible lighting for city,highway and freeway driving. Thedriver can configure its mode ofoperation in the Audi drive selectvehicle dynamics system. One special component of adap-tive light is smoothed dynamicheadlight leveling. A video camerais used to detect vehicles aheadand oncoming vehicles; then thecontrol module adapts the car‘slighting to the distance to theother vehicles – via a soft transi-tion that always maximizes theamount of illumination. The all-weather light illuminatesthe area in front of the car signifi-

cantly better than with fog lights.Depending on the specific systeminstalled, this function might beimplemented by activating the sta-tic turning lights in addition toother lights, which improves late-ral illumination considerably. Inaddition, the xenon units (withxenon plus headlights) may beswiveled downward, and theLEDs (on LED headlights) thatare responsible for the low-beamlight might be switched off ordimmed. The interplay of theseactions substantially reduces „self-glare“ to the driver. In the A6, A7 Sportback and A8model series, an additional func-tion is activated as soon as theoptional night vision assistant

detects a pedestrian. The systemflashes three light pulses to thepedestrian with the high-beamlight according to the specificsituation. This clearly highlightsthe person and surroundings andwarns the pedestrian. The systemdetects any oncoming traffic toavoid any potentially hazardousglare.

Networking of the headlight con-trol module with the MMI Navi-gation plus system represents aunique selling proposition ofAudi. The navigation system‘sroute data enables such functionsas early activation of higher free-way lighting range as the car isabout to enter the freeway. Route data is also used in the city.Close networking lets the lightingsystems implement prepared solu-tions as needed. On city streets, awider angle of the light patternbetter illuminates the areas to theleft and right in front of the car.In addition, whether within oroutside city limits, the systemactivates the intersection lightimmediately before reaching anintersection, which makes it easierfor the driver to look down crossstreets. When turning, the corne-ring light is activated, which illu-minates the curve better - eitherin the city or on highways.

Another benefit is that in coun-tries like England the headlightsare automatically switched over toleft-hand traffic.

In updating its high-performancesports car, the R8, Audi intro-duced another innovation to pro-duction cars – a turn signal withdynamized display. It sends clearersignals to the environment thanconventional turn signals. This technology from Audi – whichis used in the taillights – makesthe turn indicators smarter. Whene.g. operated as turn signalflashers, their light always runstowards the side in the directionthe driver wishes to turn. Thisfunction is implemented on each

side by a band of 30 LEDs withseven segments that are sequen-tially activated every 150 milli-seconds.

Audi is already developingtomorrow‘s lighting technologiestoday, and four key trends areclearly discernible here: TheAudi vehicle lighting will reacteven more precisely to condi-tions of the environment, it willcommunicate with it in a varietyof ways and thereby furtherincrease active safety.Lighting of the future will fea-ture full-electronic control andwill be even more attractive anddistinctive based on new dynamicfunctions.

The technology of the future isknown as Audi Matrix LED head-lights – it subdivides the LEDhigh-beam light into numerousindividual segments. The indivi-dual light-emitting diodes, whichwork in tandem with lenses orreflectors in front of them, alwaysdeliver excellent illumination,without requiring a swivelingmechanism – instead they areseparately activated, deactivated ordimmed according to the situa-tion. This new technology givesAudi engineers and designers fas-cinating possibilities for confi-guring the number of LEDs, theirarrangement and the size anddesign of the headlights. The Audi Matrix LED headlightsget the information they needfrom a camera, the navigationsystem and other sensors. Whenthe camera detects other vehicles,this causes the high-beam light,which is subdivided into multiplesectors, to be blocked in a certainsubarea. In complex situations,the headlights can also illumi-nate the spaces between severalvehicles. Based on navigation data, the highbeam light predictively swivelsinto the curve even before thedriver begins to turn the steeringwheel. Essentially, the high beamlight guides the driver along theroad. This functionality is alsoreflected in the special headlightdesign. Illumination of the seg-ments can also be experiencedfrom outside. The matrix LEDheadlights will make their debutlater this year.

The EU has set some ambitioustargets for vehicle manufacturers:by 2015, Germany's new car fleetaverage will have to achieve amandatory target of 130 gramsCO2 per kilometer. The federalgovernment has raised the bareven higher by pledging to increasethe number of electric vehicles onGermany’s roads to 20 percent by2020. At the same time, driversare demanding ever greater levelsof safety and comfort. This apparentcontradiction calls for new, inte-

grated approaches. Lightweightdesign and material substitutionare essential, but not enough inthemselves. Activation on-demandinstead of wasteful continuous useis one way of conserving resources.This can be achieved by electrifyingthe ancillary components; an ideawhich is prompting developers inthe drives division of automotivesupplier Brose to introduce forward-looking solutions. For example,electro-mechanical steering with on-demand functionality increases effi-

ciency and so reduces emissions byaround 7 grams CO2 per kilometer;drive train actuators with on-demandoperation and optimized transmissionreduce energy consumption and cutCO2 emissions by up to 10 grams perkilometer.

It's really very simple: power offuntil needed! And yet the majori-ty of vehicle manufacturers leave

in modular form (componentassembly kits) which can be flange-mounted or built in. Torque rangesfrom 2.5 to 23 newton-meterswith performance levels from 250to 900 watt. Requiring very littleadaptation, the drives can be usedfor cross-model applications in allvehicle classes: from column drivefor small cars to pinion drive forthe lower mid-range and rackdrive for mid-range and luxurycars. All three drive versions aredesigned as electronically commu-tated inner rotors. At under 1.5percent at maximum temperature,they have the smallest torque rippleon the market for optimum noisereduction. Efficiencies of around80 percent are achievable with theaid of rare-earth magnets. Thedrives comply with specification ata temperature range of -40 to+125 °C and are short-circuit-proof and therefore fail-safe withoutthe need for additional components.

This system also features a smallelectric drive in the transmissionwhich cuts fuel consumption andat the same time makes for a moreagreeable driving experience: anelectronically controlled gear changeensures a shifting point designedfor optimized fuel consumption.

and CO2 emissions by around 7grams per kilometer. The operating principle: a sensoron the steering column detectsthe steering torque applied by thedriver; this information is thentransferred to the electronic controlunit (ECU), which calculates howmuch steering assistance is requi-red. The drive transmits thenecessary steering torque via aball screw to the steering rack,which then moves in the desireddirection. This ensures that steeringassistance is provided according toengine speed and steering maneuver.Greater driver comfort is alsoachieved: maximum power assistanceis delivered when the vehicle isdriving slowly, which makes parkingeasier, for example. When drivingat speed, such as on the motorway,the electro-mechanical solutionensures safe and reliable maneuvera-bility. The system also allowsadditional functions such as parkassist or lane departure warningsystems and driver steeringrecommendation to be integratedinto the electronic stabilizationprogram (ESP).

Brose supplies non-wearing, elec-tronically commutated, permanentmagnet excited synchronousmotors for power steering drives

their hydraulically driven ancillarycomponents running during theentire time that the engine is running.Take power steering for example:although this is needed on averagefor only around 5 percent of thejourney, hydraulic solutions wherethe combustion engine continu-ously drives the oil pump are stillwidely used. This means thatenergy is consumed throughoutthe journey time – even when thedriver is not moving the steeringwheel. With electro-mechanical steeringsystems this is not the case, sincepower assistance is activated onlyas required. This has the effect ofreducing fuel consumption by upto 0.5 liters per 100 kilometers

This makes it easier for the driverto operate the clutch and to selectand engage the gear. The transfercase, automated transmission andlocking differentials are also drive-assisted. With dual clutch trans-mission, this technology can saveup to 10 grams CO2 per kilometer.Brose is a world market leader inthe design and manufacture ofmotors for drive train actuators(DTAs) with extensive experienceacquired through series produc-tion of around 11 million units.It is continuously developing itssystems to make them smaller andmore efficient than other conven-tional components: virtually wear-freeand configured as inner rotors, thesynchronous motors achieve effi-ciencies of over 80 percent andspeeds of up to 12,000 rpmdepending on size. They cover apower range of up to 700 watt,depending on the model, and havebeen designed to ensure an ope-rating life of more than 6000hours. Electronic drive controlgenerally allows operating pointsto be freely selected independentlyof characteristic curves.A further advantage of this gene-ration of motors is the high degree ofstandardization: five motor sizes

ranging in diameter from 39 to 78mm are available with a choice offour different housing designs.Four electrical interfaces (electronics,sensors, contact units and connectors)may be selected in combinationsthat meet specific customerrequirements. The software includedwith the electronics is perfectlytailored to the drives because as asystem supplier, Brose developsand manufactures the mechanical,electrical and electronic compo-nents in-house.

The electrification of ancillarycomponents has only just begun:to equip vehicles for the challengesthat lie ahead, designers at Broseare exploring other applicationsthat may benefit from componentelectrification as a means of in-creasing efficiency; for examplean electric coolant pump whichcan achieve fuel savings of around2 percent. The mechatronicsspecialist also sees an opportunityto bring over 50 years’ experiencein electric motor design to thedevelopment of new systems for

the electric mobility market. Stillin the conceptual stage at presentare battery cooling systems, A/Ccompressors and electric brakeboosters.

IFrom 0 to 100 km/h (62.14 mph)in 7.6 seconds and a top speed of222 km/h (137.94 mph) – the AudiA3 Sportback e-tron adds an extrahighlight to the sporty characterof the compact premium car line.In accordance with the ECE stan-dard for plug-in hybrid vehicles,its average CO2 emissions are amere 35 grams per km (56.33g/mile) – equivalent to consumpti-on of 1.5 liters of fuel per 100 km(156.81 US mpg). Thanks to the ultra lightweightconstruction philosophy of Audi,the unladen five-door model com-plete with all electrical compo-nents weighs less than 1,580 kilo-grams (3,483.30 lb), with space forfive occupants and plenty of cargo.It comes complete with all thebrand‘s strengths – elegant design,sporty chassis, top-notch ergono-mics, excellent build quality andan extensive choice of high-endassistance and infotainmentsystems. The 1.4 TFSI combustion engineis one of the most modern powerunits of Audi. Inside the enginecompartment, looking in thedirection of travel, it is positioneda few centimeters further to theright than usual, to create spacefor the high-voltage components.

Its crankcase is made from diecastaluminum, weighing little morethan 100 kg (220.46 lb). The four-cylinder engine is stateof the art in every respect – its lowfrictional losses, its turbocharger,its intercooler and its thermalmanagement. One special featureis the way the exhaust manifold isintegrated into the cylinder head.After a cold start, it brings thecoolant swiftly up to operatingtemperature. At high loads thewater jacket lowers the tempera-ture of the exhaust gas.Thanks to the high electric rangeof up to 50 kilometers (31.07

miles), many customers will onlyrarely experience the gasolineengine of the Audi A3 Sportback e-tron in action.Another effect of the plug-inhybrid concept is that the TFSI isoften only activated in kickdownsituations, and is therefore subjec-ted to high loads while still cold.For that reason, the developershave equipped it with a variety ofprotective features. These includemodified cylinder liners and pistonrings, plus a sensor to measure oilquality. Developing 110 kW (150 hp) and250 Nm (184.39 lb-ft), the 1.4

The A3 Sportback e-tron from Audi is a latest-generation plug-in-hybrid car. The premium compactvehicle will go on sale from 2014 and is a genuine Audi. It combines sporty power with impressiveefficiency and abundant driving enjoyment with unrestricted everyday utility. The A3 Sportbacke-tron offers 150 kW (204 hp) of system power and achieves average consumption of only 1.5 liters per100 km (156.81 US mpg) of gasoline. In the electric mode its operating range is up to 50 kilometers(31.07 miles), with the TFSI engine adding a further 890 km (553.02 miles).

components of the occupant cellform an especially strong struc-ture. Its housing and interiorstructure are equally of a verysturdy design. The 12-volt battery for the low-voltage consumers and the 40-liter (10.57 US gallons) fuel tankare located above the rear axle.Both components barely impingeon the trunk of the A3 Sportbacke-tron – in the standard configu-ration it measures 280 liters (9.89cubic ft) and 1,120 liters (39.55cubic ft) with the rear seat backsdown. Audi supplies the A3 Sportback e-tron with a universal charging leadas standard. The customer caninterchange the connecting plugsso that the lead can be used bothwith domestic power sockets andwith industrial power sockets, forfull charging performance. Theseconnecting plugs are country-spe-cific in design, so that the A3Sportback e-tron can be rechar-ged anywhere in the world. For easy use at home, the char-ging lead can be clipped into awall-mounted holder. Even thisholder has an Audi design, and aswell as being a convenient way tostore and use the lead, it is lock-able. The charging equipment isthus protected against theft evenwhen kept outdoors. The char-ging lead supplies the car with

tween 280 and 390 volts. The bat-tery consists of 96 prismatic cellsarranged into eight modules oftwelve cells each. Including theelectronic components – the bat-tery management controller andthe battery junction box – thebattery system weighs 125 kilo-grams (275.58 lb). Its housing isbolted to the vehicle floor at fivepoints, and the lower shell is madefrom aluminum. An elaborate liquid coolingsystem ensures that the battery iskept within a suitable temperaturerange during operation. Drivers ofthe Audi A3 e-tron will be able tostart electrically in hot summerconditions and at sub-zero wintertemperatures alike. Four coolingplates regulate the temperature ofthe high-voltage battery‘s eightmodules. The cooling systemrepresents a separate low-tempe-rature circuit in the car and runson a separate cooler housed in theengine compartment. If need be,it can be connected to the air con-ditioning system and even dividedinto two subsidiary circuits. In the event of a crash sufficientlysevere to trigger the belt tensio-ners or airbags, the entire systemis disconnected from the powersupply. The flat-shaped battery isinstalled under the rear bench seat– an area where the high-strengthand ultra-high-strength steel

TFSI is a powerful unit. It sup-plies peak torque across the entirespeed range from 1,750 through4,000 rpm, thus harmonizingexcellently with the electricmotor. The maximum of 330 Nm(243.40 lb-ft) is available virtuallyfrom the off, and is maintainedconstantly across a broad speedrange up to about 2,200 rpm. Itsmaximum output is 75 kW. Thesystem output of the A3 Sport-back e-tron is 150 kW (204 hp), and system tor-que is 350 Nm (258.15 lb-ft).With the combination of electricmotor and combustion engine, anoverall operating range of up to940 kilometers (584.09 miles) ispossible. And its road performan-ce is unwaveringly sporty: It takesa mere 4.9 seconds to sprint from0 to 60 km/h (37.28 mph). The electric motor is a perma-nently excited synchronousmachine. It weighs 34 kilograms(74.96 lb) and is liquid-cooled viaa cooling jacket in the stator. Theelectric motor is located betweenthe engine‘s dual-mass flywheeland the newly developed separa-ting clutch, the K0 clutch. Whenthe TFSI starts, it is tow-startedby the electric motor via theclutch. As soon as the former hasachieved the same speed as theelectric motor, the clutch is opened.This smooth, highly precise pro-cess takes place within half asecond. Together with the K0 separatingclutch, the electric motor is inte-grated into a newly designed six-speed e-S tronic, which transfersthe power to the front wheels.Like all Audi dual-clutch trans-missions, it consists of two subsi-diary transmissions that are servedby the two multi-plate clutchesK1 and K2. Gears are shifted byswitching the clutches. This takesjust a few hundredths of a secondand happens without any notice-able interruption in propulsivepower. Depending on the level ofcharge, the voltage ranges be-

alternating current from the gridvia the charging connection,which is in the Singleframe grillebehind the fold-out four rings. Aswell as a status LED, the unitincludes two pushbuttons allo-wing the user to choose betweentimer-controlled charging andimmediate charging. In the car,the alternating current fed in bythe charger is converted intodirect current for the battery. From an industrial power socket,it takes slightly more than twohours to charge the battery fully.From a normal domestic powersocket in Europe, the chargingprocess takes about three hoursand 45 minutes. Audi is workingintensively on a joint project witha supplier of renewable power,because electric driving onlymakes ecological sense if suchpower is available. Another medium-term project ofAudi is automatic charging with-out physical contacts, referred toas Audi wireless charging. Herethe charging process involves analternating magnetic field be-tween the stationary charging padon the ground and the mobilecharging pad in the car, similar tothe principle used by an electrictoothbrush. The power electronics, located inthe engine compartment, thenconvert the stored direct currentinto three-phase current for theelectric motor. It has six high-per-formance transistors for this task.The power electronics, whichinclude a DC/DC converter forconnecting up the vehicle‘s 12-volt electrical system, are compactand light in weight. They have atotal volume of 8 liters (0.28 cubicft) and weigh 10 kilograms (22.05lb). Together with the charger, itis incorporated into the same cool-ing circuit as the traction battery. There are yet more special com-ponents for electric driving. Theair conditioning compressor hasan electric drive integrated intothe high-voltage network. A ther-

moelectric heating element and agasoline-powered auxiliary heaterround off the interior heatingsystem. The hybrid management is confi-gured to function in harmonywith the electric motor. Up tomedium loads the electric motor,now functioning as alternator, lar-gely handles retardation. Theenergy that it recovers is fed intothe traction battery. The wheelbrakes only become active if thedriver presses the pedal moreforcefully.Braking recuperation is just one ofseveral operating statuses of theAudi A3 Sportback e-tron. Thecar is almost always started elec-trically, even at very low tempera-tures, in extremely hot conditionsor when battery charge is verylow. The electric motor‘s hightorque enables the sporty compactcar to accelerate away powerfully.It goes from 0 to 60 km/h (37.28mph) in 4.9 seconds – with quietbut forceful propulsion. In the electric mode the Audi A3Sportback e-tron can travel at upto 130 km/h (80.78 mph) – it couldgo faster, but that would not beefficient. When traveling at a con-stant 100 km/h (62.14 mph), gene-rally only the electric motor is

active provided there is sufficientenergy in the battery. As soon asthe driver steps hard on the accel-erator, for instance to overtake,and causes the pedal to go beyonda certain resistance point, itprompts the TFSI to cut in viathe K0 separating clutch. In theboost mode the Audi A3 Sport-back e-tron accelerates with all of350 Nm torque (258.15 lb-ft). When the driver releases theaccelerator at high speed, thehybrid management enters thegliding mode. Now both drivesare entirely deactivated and are nolonger developing braking torque.When stepping off the acceleratorat medium and low speeds, thesystem recovers energy throughcoasting recuperation; brakingrecuperation then becomes activewhen the brake pedal is pressed,except if a full brake application isneeded. The driver has several ways ofactively managing the vehicle‘sresponse. They can choose fromthree programs using a button inthe driving area and the e-S tronic selector lever. The EVcharacteristic map gives priority toelectric drive, whereas the AudiA3 Sportback e-tron behaves verysportily in the S program. The

In the meantime the family-owned Company founded in Marktredwitz has become a global player. The medium-sized Group of Companies is still directed by its owners and has 29 locations world-wide.

According to the slogan “Progress based on tradition – growth by innovation” developed by the Group Managing Director Walter Bach the range of services has also been extended. Besides the forming and assembly divisions, construction of machines, tools and installations as well as surface treatment are also part of the product range.

Despite the international activities, the production, research and development as well administration divisions are still primarily based at the Company’s “place of birth” in Upper Franconia. At a global level, more than 4,000 employees sustain the Group’s success.

As a reliable partner SCHERDEL realizes innovative products for various areas. SCHERDEL guarantees complete solutions from the initial idea to the series production. The Group’s image is based on high-quality products used in the automotive sector as well as in medical devices, electronical applications and household appliances.

New forms of mobility are necessary to guarantee, also in the future, a quick, safe, comfortable and ef"cient transport for human beings and goods while preserving the resources. This requires the development of new drive systems with the necessary components. SCHERDEL actively participates in this challenge by offering innovative solutions.
