VW Fuel Cell
The Touran HyMotion represents the future of environmentally-friendly
transportation. Hydrogen fuel cell technology permits the Touran HyMotion
to be a 100 percent emission-free vehicle. Its only by-product is water.
The core element of the Touran HyMotion’s fuel cell technology is a thin plastic
membrane used to separate hydrogen and oxygen. Once separated, the
hydrogen is broken down into its constituent charged particles, protons and
electrons. The protons pass directly through the membrane, while the electrons
take a more indirect route to drive the Touran HyMotion’s high-torque 80 kW
electric motor. At the end of the process the protons, electrons, and oxygen
combine to form water.
Two and a half kg of hydrogen are stored in gaseous form in the vehicle’s fuel
tank. This amount of fuel corresponds roughly to the amount of energy in two
and a half gallons of gasoline, which permits the Touran HyMotion to drive
approximately 120 miles. The Touran HyMotion also is fitted with a NiMH
high-power battery to enable a rapid starting procedure and efficient response
during acceleration. The Touran HyMotion accelerates to 60 mph in 14 seconds
and has a top speed of 87 mph.
The Touran HyMotion is located at Innovative Mobility Showcase outdoor
exhibition. Visitors will have an opportunity to ride in the Touran HyMotion
and interact with leading engineers from Volkswagen’s Research and
Development Department.
Its only by-product is water.
VII for Safety and Mobility
The Vehicle-Infrastructure Integration (VII) California program is a
collaborative effort between OEMs and the public sector. Its aim is
to enhance vehicle safety and mobility by connecting cars with each
other and with the surrounding infrastructure via 5.9GHz Dedicated
Short Range Communication (DSRC). Partners in this demonstration
include Caltrans, Metropolitan Transportation Commission,
NAVTEQ, and Econolite.
5.9GHz DSRC is a wireless communication protocol similar to IEEE
802.11a; however, it operates within the 5.9GHz band and is dedicated
solely to automotive applications. This protocol also is known as
IEEE802.11p Wireless Access in Vehicular Environment (WAVE).
Volkswagen’s VII for Safety and Mobility demonstration at this year’s
Innovative Mobility Showcase outdoor exhibition will show multiple
DSRC-based safety and mobility applications, including intersection
safety, vehicle probe data, car-to-car information sharing,
location-based point-of-interest information retrieval, and real-time
traffic incident updates. These applications will be demonstrated during
a narrated ride-along on a route through the city of San Francisco.
During the ride-along, experienced engineers from Volkswagen’s
Research and Development Department will explain the DSRC
technology and its uses.

Advanced Electronics
The Advanced Electronics demonstration at the Innovative Mobility
Showcase outdoor exhibition will showcase Volkswagen production
vehicles. Aided by a DVD-based navigation system, visitors can test drive
and experience these vehicles on a route that runs through the city of
San Francisco.
At the exhibition, staff members will explain relevant technologies.
Showcased technologies include Electro-mechanical Power Steering
that modulates torque assistance as a function of vehicle speed;
Electronic Stabilization augmented with Anti-Slip Regulation and
Electronic Differential Locking for added vehicle control during
challenging driving conditions; and Dynamic Starting Assistant for
improved driver acceleration performance when starting out from an
incline. The demonstration also will show Volkswagen’s new 600 Watt
premium sound system from Danish Hi-Fi specialist Dynaudio.
Car-to-Home
Car-to-Home seeks to interconnect wireless-enabled homes with
Volkswagen cars, providing added value to customers by combining
digital and mobile lifestyles. Through a wireless LAN, with access
provided through WebServices, users can connect to and interact
with many vehicle features and future add-on-devices from their home
computers and other digital outlets.
With an intuitive graphical user interface, customers can use
Car-to-Home to receive car status information, configure vehicle
settings, plan and review travel activities, and upload multimedia.
For example, one can pre-heat or pre-cool the vehicle before a drive,
plot an optimal travel route along multiple destinations, review travel
times, fuel efficiency, average speed, and finally, upload MP3s and
video for entertainment purposes.

Challenge
Our challenge as an automotive company is to continuously research
and develop new technologies that increase the safety and efficiency
of our products while maintaining the driving fun factor. To this end,
we always must look ahead to see oncoming obstacles or hazards
and make informed decisions about how to deal securely with them.
That is our grand challenge.
The Grand Challenge Touareg is a feat of modern engineering.
It is a self-driving vehicle featuring a battery of sensors that allow it to
traverse terrain where most drivers would fear to take their vehicles.
The goal of the Enhanced 3D Navigation Concept is to provide
the driver with a high-quality 3D representation of the surrounding
environment. The Enhanced 3D Navigation Concept combines
high-performance graphics and software with highly detailed map
data to provide these representations.

Grand Challenge Touareg
Safe and effective driving requires situation awareness, i.e., knowledge
of the surrounding environment. Situation awareness is the result of
terrain analysis and obstacle detection, information evaluation, and
subsequent decision-making strategies about steering, braking, and
acceleration. The Grand Challenge Touareg places these processes
squarely in the hands of an array of sensors and computers. Specifically,
the vehicle is outfitted with six Pentium M computers, a global
positioning system, long-range radar, camera, five laser range-finders,
and a full drive-by-wire system for actuating the car’s functions.
The Grand Challenge Touareg, known as Stanley, is Volkswagen’s
answer to the 2005 DARPA Grand Challenge, a 10-hour 175-mile robot
race stretching across the Mojave Desert in the Southwestern U.S.
Recently, the Grand Challenge Touareg won the race and
accompanying $2 million prize against of field of 22 other autonomous
competitors from universities and private companies around the world.
The Grand Challenge Touareg is not simply an exercise in creating
a vehicle that can drive itself. The technologies used in the
Grand Challenge Touareg are similar to those that Volkswagen will
use in future “Driver Assistance” systems, such as lane-keeping and
obstacle-avoidance systems. The ultimate goal of this project is to create
safer roads by augmenting human capabilities with driver assistance
systems that help prevent accidents.
Enhanced 3D Navigation Concept
High-quality 3D representations of environments are becoming
commonplace in on-line search engines and navigation. These high
quality images and text can inform the user more effectively than those
of lower quality. Bringing these same features into a vehicle navigation
system is the next step in enabling the mobile lifestyle.
The Enhanced 3D Navigation Concept brings together the power of
the leading graphics chip maker nVidia, the navigation and search
engine capabilities of Google, and the automotive expertise of the
Volkswagen Group. By combining state-of-the-art graphics processing
technology with detailed 3D map data and navigation functionality,
Volkswagen presents a glimpse into the future of vehicle navigation.
3D data collection of buildings and terrain is facilitated by satellite
imagery and terrestrial laser range-finding technology, the latter
being the same that is found on the Grand Challenge Touareg.
Complementing these detailed databases with high quality graphics-
rendering capability, navigation systems will provide the driver with
a more complete representation of the environment.
Performance
Humans are driven to perform, and we strive to be the best on any
road, whether it is snow-covered, paved or not there at all. Our vehicles,
two wheels or four, willingly take on any trail that we have in mind,
inspiring us with confidence that they use the finest technology. This is
our commitment to all roads.
The Audi allroad quattro concept demonstrates its versatility through
meticulous attention to design and engineering. From the functional
elements of an off-roader, to the rugged rally-proven quattro all-wheel-
drive system, to the high-technology Audi road vision and radar
detection systems, the allroad is the very definition of the modern
sporting vehicle. If, however, your destination is the single-track dirt road,
the Alltrail Bike is the vehicle of choice. With an advanced electronic
braking system, the Alltrail Bike provides riders with unparalleled
stopping power and control.

● Audi allroad quattro concept● Alltrail Bike
Alltrail Bike
Riders tend to panic in dangerous situations by immediately squeezing
the brake levers to lock the brakes. This action frequently causes the
front wheel to skid, resulting in a loss of control and a disastrous crash.
The Alltrail Bike was inspired by the enhanced safety features of our
automobiles; however, it incorporates these features into a two-wheel,
human-powered form. Just as anti-lock braking systems (ABS) and
brake-by-wire have enhanced driver control and safety in automobiles,
the same technology exists in this one-of-a-kind Alltrail Bike.
Powered by a lightweight high-capacity Lithium-ion battery, the electronic
braking system uses caliper-mounted sensors that read bike speed,
rider input to the brake levers, and brake pressure. This information is
fed via a Control Area Network bus to the main brake controller. The
main brake controller processes this information through an anti-lock
braking algorithm and subsequently talks to a motor to modulate the
brake hydraulic pressure and prevent front wheel lock-up. The end result
is the rider coming to a complete stop in the quickest and safest
manner possible.
15
Audi allroad quattro concept
Through its design alone, the Audi allroad quattro concept clearly demonstrates
its versatility. The elegant sporting character of the Audi Avant is visibly linked
to the functional elements of an off-roader, creating a vehicle that is just as much
at home on the highway as it is on a snowbound mountain track.
A brand-new power unit is all set for action within the engine bay. Displacing
four liters, the V8 TDI that boasts common rail fuel injection and piezo injectors
is the world’s most powerful and advanced eight-cylinder self-ignition engine.
Maximum output of 210 kW (286 bhp) and peak torque of 650 Newton-meters
ensure the muscle and performance of a thoroughbred sports car. Featuring
six-speed automatic transmission, the allroad quattro concept accelerates to
100 km/h in just 6.4 seconds, with top speed limited electronically to 250 km/h.
Audi road vision is an outstanding world-first achievement, an optical sensor
system able to recognize the condition of the road and its surface, thereby
providing a quantum leap in terms of driving safety. The system not only informs
the driver of potentially critical conditions such as gravel or black ice but also
gives the ESP electronic stabilization program and the adaptive cruise control
additional, crucial parameters for even better proactive control.
Audi lane assist, another feature of the concept car, induces vibrations on the
steering wheel to inform the driver as soon as he inadvertently leaves his lane.
Audi side assist, in turn, incorporates radar sensors to monitor the area behind
and next to the car. Once the system detects vehicles approaching the Audi
allroad quattro concept or driving in the car's blind angle, the driver is informed
accordingly by a warning light that appears in the exterior mirror on the
appropriate side.

Anti-lock Braking System
Mobility
Mobility is the capacity to move ideas, technology, and people.
Mediated through information sharing devices and services in our
homes and vehicles, mobility brings a new level of information
accessibility and entertainment convenience to the driving experience.
Mobility is realized through various ongoing efforts at Volkswagen, such
as Nomadic Device Concept, Event Online, and the Advanced Interface
Concept. The Nomadic Device Concept provides a means to interface
your latest mobile device and your vehicle. For example, future portable
devices will transparently share contact information as well as other
digital media with a vehicle’s onboard information systems. Event Online
combines real-time traffic data from different sources to improve traffic
management and security during large-scale events. Finally, Volkswagen
is exploring the use of Advanced Interface Concepts like natural
language and handwriting recognition technology for interfacing
emerging technology devices and services with the human element.
17
● Nomadic Device Concept● Event Online● Advanced Interface Concept
Event Online
Event Online is a service concept for traffic management during large-scale
events. Event Online combines real-time traffic data from two different sources:
Floating Car Data (FCD) on the ground and camera images from helicopters
(i.e., “Eye in the Sky”). The purpose of Event Online is not only to increase
throughput for event spectators but also to provide added security and
improvements in emergency response during events such as the Olympic Games.
FCD was developed by gedas and is a registered patent of the Volkswagen
Group. The idea behind FCD is to equip public transport and shuttle fleets with
mobile devices such as PDAs, MDAs, or navigation systems connected to a GSM
module for periodic data transmission. Data such as average travel time, speed,
and disturbances will be sent by this network of vehicles to a service center.
Based on mathematical models, these data then will be processed in a traffic
management center and used to identify traffic problems. Together, FCD and
real-time imagery gathered from the “Eye in the Sky” will be combined and used
to inform event coordinators for traffic management, security, and emergency
response strategies. For example, these data can be used to re-route event
spectators around highly-congested areas or guide emergency response vehicles
into a designated area as efficiently as possible.
Event Online recently was put through a live test in Berlin, Germany. During the
test a fleet of vehicles transmitted real-time FCD via SMS text messaging to a
traffic control center at Fraunhofer IPK. If FCD indicated traffic congestion, the
“Eye in the Sky” came into action over the potential bottleneck. A high resolution
DLR camera feed was sent from the helicopter to traffic controllers via a SatCom
radio connection.
19
Nomadic Device Concept
Modern lifestyle has changed dramatically with the permeation of
nomadic devices in our everyday lives. MP3 players, PDAs, smart
phones, gaming devices, and a suite of other nomadic devices have
revolutionized the mobile consumer electronics industry. Today, drivers
and passengers spend a considerable amount of time in their cars and
expect the same level of comfort and convenience doing the activities
they are used to outside the car. As a result of this consumer demand,
manufacturers today are taking on the challenge of enabling nomadic
device usage seamlessly in cars.
In addition to hosting various concepts in mobile device integration,
the Nomadic Device Concept car showcases numerous mobile services
enabled by such integration. The MacMini is an efficient computing
platform that acts as a gateway for all nomadic device integration
and mobile service usage. All the seemingly complex tasks implied
by such a mobile network within the car are delivered through user-
friendly interfaces.
The true essence of the concept car, however, is not the number of
nomadic devices it enables the driver to use. Rather, it is the capability
to use the latest consumer electronics without a major hardware or
software revision.

Advanced Interface Concept
Volkswagen is exploring advanced interface concepts for interacting with a
variety of in-vehicle systems such as navigation, infotainment systems, and vehicle
settings. The ever-increasing amount of information available in the car
necessitates innovative methods to simplify interaction and to access data.
The Volkswagen Advanced Interfaces demonstration kiosk showcases two new
technology applications: Handwriting Recognition for input of Chinese characters
and a Natural Language Dialog System for conversational interaction with
various devices.
Using a touchpad that can be placed anywhere in the vehicle, the Handwriting
Recognition application allows unprecedented ease of entering Chinese
characters into a navigation system and other information devices for the
Chinese market. The system also can be tuned to recognize other pictorial-based
languages and Latin characters and can be implemented in a touchscreen.
Overall, this technology dramatically shortens the time needed to input words
and names in the car.
New developments in conversational Natural Language technology also give
drivers more flexibility and ease while interacting with complex systems. This kiosk
application shows the power of a conversational interface for accessing music in
the vehicle. Besides simply issuing commands via the speech recognition system,
users can carry on dialogues on multiple topics, ask for lists of songs, and
manipulate playlists, all the while maintaining speech command operations like
play and stop. This technology extends to other applications like points of interest
identification and navigation guidance. The Natural Language Dialog System
allows drivers to perform complex system tasks with less distraction and
shortened learning times.
