`
`to millions of commuters who
`
`spend hours each day cruising the roads or
`stuck in traffic.
`It is designed to demonstrate
`what technologies and software can do for the
`vehicle of the future. The Network Vehicle,
`
`at
`its debut
`1, made
`pictured in Figure
`COMDEX ’97 and has since been all over the
`world appearing in demos, conferences, and
`technology shows,
`including SAE Congress
`’98, and CeBit ‘98.

`
`ABSTRACT
`
`the Delphi
`The Network Vehicle is
`the future
`Automotive Systems’ vision for
`convergence of computers, the communications
`infrastructure, and the automobile.
`It features
`many advanced functions
`such as:
`satellite
`video,
`Internet
`access,
`virtual
`navigation,
`remote vehicle diagnostics and control, games,
`mobile office,
`automotive web
`site,
`and
`customized real—time stock quotes and sports
`scores.
`These features are enabled by an
`integrated planar antenna that
`is capable of
`multiple
`satellite
`reception,
`client-server
`a
`network
`architecture,
`and
`unique
`human-
`vehicle-interfaces such as color reconfigurable
`head up and head down displays,
`steering
`wheel controls, voice
`recognition,
`text—to-
`speech, and large touch screen active matrix
`liquid crystal displays (LCD’s). The software
`applications
`are written
`in
`Java,
`using
`Application Programming Interfaces (API’s) to
`reduce the complexity and cost of the source
`code.

`SYSTEM OVERVIEW
`The Network Vehicle is created by
`integrating existing hardware and software
`technologies
`including
`voice
`recognition,
`wireless communications, global positioning
`via
`satellite,
`head—up
`displays,
`Java”
`technology, microprocessors, Web access, and

`
`A
`
`functionality, gateways are used to translate the
`messages from one sub-network to another so
`as to ensure harmonious operations.

`
`Figure 2. Onboard Network Architecture
`
`shown in
`The off-board network is
`Figure 3. The high bandwidth requirements for
`on-demand audio and video functions are
`fulfilled with DirecPC and DirecTV satellite
`broadcasts. A wireless modem provides the
`uplink out of the vehicle directly to Internet
`service providers. The downlink return path
`from the Internet to the Network Vehicle can
`come through either the satellite (400 kbps), or
`through the wireless modem. The downlink
`satellite video and data signals are collected by
`the Network Vehicle’s roof-mounted antenna
`and processed by their respective receivers.

`
`other
`Intemet/intranet
`features.
`The V0109
`recognition technology allows drivers
`and
`passengers to verbally request and listen to e-
`mail messages, locate a restaurant or hotel, ask
`for navigation help or for specific music or
`sports scores, and use voice-activated telephone
`services, all done safely without
`interfering
`with driving. Drivers can use a head-up display
`projected through the windshield to navigate to
`their destination or check vehicle functions
`
`without taking their eyes off the road.
`
`terminals
`Passengers using individual
`next to their seats can do even more, including
`interacting with
`the
`Internet, watching
`television or playing games. Existing services
`such
`as
`theft deterrent
`technologies
`and
`emergency services could also be integrated.
`These "smart"
`features are enabled mainly
`because
`of
`the
`real-time
`data-strearning
`capabilities over a wireless network using Java-
`based technology. The Network Vehicle also
`has an integrated cellular phone, Netscape
`Communicator software for Web browsing and
`e-mail, a removable personal digital assistant
`(PDA) and docking station. There is also a
`vehicle web site that provides driver support for
`a wide array of customized capabilities such as
`enabling remote monitoring and control of
`vehicle systems in emergency situations.
`
`Onboard And Off-Board Communications
`Networks
`
`The key to the functions of the Network
`Vehicle is its ability to communicate efficiently
`both onboard and off-board of the vehicle.
`Figure
`2
`depicts
`the
`onboard
`network
`architecture of the vehicle.
`
`At the heart of the onboard system is a
`network computer that links up a number of
`sub-networks,
`including a Class H bus (for
`engine, head—up and head-down displays, door
`lock and door actuator, RFID, and cell phone,
`etc.), an Ethernet (for passenger computers and
`displays),
`and a mobile media
`link (for
`speakers
`and CD players).
`Since
`the
`subnetworks all have different clock speed and
`
`In order to take full advantages of the
`resources and services available to the drivers
`and passengers, the vehicle must have robust
`external communications paths.
`It
`is a_1S0
`vitally important that the vehicle configuration
`includes a firewall to ensure the integrity of the

`ofwhat happens to the multimedia applications
`that are running in the vehicle, the powertrain

`and other critical
`functions must

`muuiple gateways as shown in Figure 2.
`
`KEY TECHNOLOGIES AND SYSTEM
`COMPONENTS
`
`system
`and
`technologies
`key
`The
`components behind the Network Vehicle are
`advanced speech recognition software, mobile
`media link (high-speed fiber optic data bus),
`reconfigurable
`head-up
`display,
`high-
`bandwidth communications that connect
`the
`vehicle with the outside world, and a suite of
`automotive computer software. These elements
`are described below.
`
`Speech Recognition and Text-to-Speech
`System
`
`IBM has modified its advanced speech
`recognition
`and
`text—to-speech
`system,
`ViaVoiceTM, for the automotive environment.
`ViaVoice allows the driver to access virtually
`all
`the
`vehicle's
`features
`through
`voice
`commands and enables the vehicle to talk back
`using synthesized speech.
`For example,
`the
`driver can: execute vehicle system commands
`such as lock doors, play CD, and change radio
`station,
`request
`travel directions and traffic
`updates from the Web or other sources, check
`e—mail and voicemail, request news, sports, and
`stock information.
`The speech recognition
`system can understand most drivers instantly,
`with no system training required, and it has
`been tuned to offer optimal performance even
`in a potentially noisy vehicle environment.
`
`Driver and Center Console Displays
`The Network Vehicle is equipped with
`three displays for the driver:
`the head-down
`
`the head-up display (HUD),
`display (HDD).
`and the center console display.
`
`standard
`T116 HDD system displays
`graphics for an instrument panel: road speed,
`engine speed, engine status, door lock/ajar, and
`fuel level.
`It also displays the functions for the
`steering wheel buttons since these functions
`
`is
`vary with the entertainment mode that
`selected. The HUD projects a virtual image
`through the windshield that gives information
`to drivers without requiring them to take their
`eyes off the road.
`It displays road speed,
`engine
`status, waiting
`e—mail
`indication,
`navigation information, microphone on/off, and
`a text message area for giving feedback to the
`driver.
`
`The center console's touch-screen LCD
`
`serves as a user interface for controlling nearly
`all of
`the Network Vehicle's multimedia
`
`(office, navigation, entertainment,
`functions,
`and information). When in entertainment
`mode, the display is configured as a radio- or
`CD-style faceplate whose buttons and controls
`are activated by touch (see Figure 4).
`It is
`reconfigured to display e—mail, navigation
`maps, Web browser, cellular phone faceplate
`(shown in Figure 5), and more.
`Voice-
`activated commands can be used with all of the
`center console functions and, in some cases, is
`
`
`
`
`text-to-speech
`combined with
`input
`to
`rriinirnize driver distraction.

`
`The Network Vehicle has color LCD
`
`touch panels for the back-seat and front-seat
`passengers. As with the center console display,
`the passenger displays serve as user interfaces
`for controlling nearly all of the functions on the
`Network Vehicle. Unlike the center console
`display, however,
`the passenger displays can
`show video from DirecTV or DVD players, and
`they allow touch—screen access to all functions.
`
`Planar Satellite Antenna
`
`The antenna technology used in the
`Network Vehicle is the Continuous Transverse
`Stub (CTS) array.
`It is chosen because of its
`simplicity, planar construction, and potential
`for being an inexpensive product.
`Figure 6
`shows the cross sectional view of a typical CTS
`antenna,
`realized as
`an
`array of broad
`continuous transverse radiating stubs, finite in
`height, extending from the upper conductive
`plate of an open parallel-plate transmission-line
`structure.

`As a receiving antenna,
`longitudinal current components in the parallel
`plate structure are interrupted by the transverse-
`oriented stubs and excite propagating waves in
`the
`parallel—plate
`structure.

`simple
`architecture
`allows
`for
`a
`complex
`two-
`dimensional planar array to be realized as an

`services provided by automotive-oriented ISPs
`(Internet Service Providers).
`The customer
`service site developed for the Network Vehicle
`showcases the types of features that could be
`offered when intelligent vehicle systems are
`connected to the Internet.
`
`Because the Network Vehicle's systems
`are accessible via its command and control
`
`application, which also has secure access to the
`Internet, many
`scenarios

`the driver and passengers can
`obtain maps, route guidance, fuel, lodging, and
`restaurant information while traveling. Owners
`of the Network Vehicle can also use their Web
`
`including

`
`Personal Digital Assistant Docking
`
`the Network
`role of
`An important
`Vehicle is providing office functions to mobile
`users, using the same data the users have in
`their office desktop computers. This function
`is
`mainly
`provided
`through
`vehicle
`applications,
`Internet
`connectivity,
`and
`advanced, voice-based user interfaces.
`It
`is
`important for the Network Vehicle to access
`and synchronize personal and business data
`with PDAs, which is becoming increasingly
`important in our mobile, connected world.
`
`A slot built into the center console of
`the Network Vehicle
`accepts
`the HSM
`WorkPadTM and uses the Network Vehicle's
`computer to add speech recognition and text-to-
`speech functions. This enables the driver to
`listen to schedules and to update files and other
`office data stored in the WorkPad.
`So the
`driver could,
`for example,
`issue
`a voice
`command to read calendar entries from the
`WorkPad or dictate a to-do list while driving.
`As PDA and smart card technology advances,
`the Network Vehicle's PDA integration could
`support the use of PDA-type devices for the
`secure
`transport
`and
`access of personal,
`financial, and business information as people
`move from one network access point
`to
`another.

`
`Under voice control of the driver,
`
`the
`
`Network Vehicle can upload vehicle status
`according to a profile set up in advance. An
`application monitors the diagnostic information
`available
`from components
`in the
`engine
`compartment. Should the diagnostics indicate
`that the latest reading from engine sensors falls
`outside a normal range,
`the application can
`notify the customer service Web site, where the
`severity of the reading can be determined.
`According to this determination, the control on
`the Network Vehicle could be used by the
`service representative to alert the driver;
`the
`alert could be done using text-to-speech and
`head-up display, and then features of
`the
`application, e-mail, and office could be used to
`arrange
`a
`service
`appointment. Figure

`
`Automotive Computer Software
`Virtual machine-based, object-Oriented
`technologies were applied to the Network
`Vehicle’s development because they support
`the special requirements posed by the Veh1C1€-
`Smalltalk,
`a well
`proven
`object-onented
`environment and the latest Javam technologies
`were chosen to develop the Network Vehicle's
`software.
`
`A command and control application,
`written in Smalltalk and running on the
`vehicle's main processor, monitors vehicle
`status, controls devices such as cell phone and
`microphone, supplies driver
`information via
`head-up
`display,
`manages
`off-vehicle
`information
`flow,
`and
`controls
`vehicle
`software, such as the voice recognition and
`various convenience passenger applications.
`This application coordinates with the voice
`recognition, the head—up display, and the touch
`screen to provide feedback and control of the
`various systems, helping to keep the driver's
`eyes on the road. For driver convenience and
`safety,
`this application also interfaces via the
`Internet to a customer service provider, who
`can remotely monitor the vehicle status, unlock
`doors, turn on exterior lighting, etc.
`
`Graphical user interfaces for Network
`Vehicle's center console and passenger displays
`are developed with Java to provide access to
`various in-vehicle and off-vehicle applications,
`such as navigation, audio/video entertainment,
`and office. An Internet server application was
`developed with VisualAge® for Java to provide
`communication
`between
`Intemet-based
`customer applications and the vehicle systems.
`These applications support a message-based
`protocol communicating through the Internet to
`the
`in-vehicle
`command
`and
`control
`application, which in turn interfaces to the
`vehicle
`systems
`and
`the
`user
`interface
`application.
`Java applets were also developed
`for
`the customer
`site in order
`to provide
`animated vehicle status and control graphics.
`
`Media BUS and In- Vehicle Electronics
`a
`The Network Vehicle
`contains
`number of audio and video components that are
`configured and controlled via a hjgh_speed
`(100 Mbps) digital
`fiber-optic mobile media
`link (MML). Audio and video devices like C1)
`players can send their output signals via the
`multiplexed,
`f1ber—optic bus
`to drive other
`components like amplifiers and displays_ A
`control signal is also carried on the MML bus
`to configure and control the devices - configure
`the components,
`switch signals, and adjust
`variables such as volume, fade, and balance,
`The MML gives the application full use of the
`vehicle’s multimedia
`systems
`to
`develop
`functions and user interfaces tailored to drive;
`and passenger use.
`
`Combining a command and control
`application with the MlVIL in the Network
`Vehicle made possible features such as context-
`sensitive volume reduction during the use of
`the phone and the text—to-speech feature.
`It
`also allows "faceplate—style" user interface to
`integrate Internet radio with the sound system,
`and common and consistent user interfaces to
`define, review, and play the audio and video
`content preferred by the driver and passengers.
`The vehicle also features a satellite receiver
`
`system, which provides DirecTV and DirecPC
`access. DirecPC offers high-speed (440 kbps)
`Internet data access while DirecTV offers over
`175
`channels
`of
`digital
`entertainment
`programming.
`
`FEATURES AND FUNCTIONS OF THE
`NETWORK VEHICLE
`
`The main features of
`the NetW0F1<
`Vehicle are manifested in the following three
`areas: (1) Driving Aids, (2) Business Tools, and
`(3) News and Entertainment.
`The Network
`Vehicle is designed such that, through softwarfi
`upgrades the customer can be provided with
`new features and functions as they become
`available.

`
`Driving Aids - Get Where You’re Going
`Efficiently
`The Network Vehicle can access a simulated
`integrated global positioning system and hence
`advanced navigation capabilities via lntemet.
`Therefore,
`it
`literally knows where it
`is and
`where it’s going.
`It can display the appropriate
`maps or simply provide route directions on the
`head-up display,
`command console or
`as
`spoken instructions. Drivers could control the
`navigation
`system using
`commands
`like
`“destination” to select a new destination or
`“route
`guidance”
`to
`get
`tum-by-tum
`instructions. An example of such a display is
`shown in Figure 9.
`
`
`
`Figure 9. Example of a Navigation Function
`Display
`
`The ability to monitor key vehicle systems
`means that the Network Vehicle can detect and
`avoid problems before they happen.
`If key
`vehicle
`systems
`show signs of
`failing,
`a
`Warning light appears on the head-up display,
`or the vehicle tells the driver what the problem
`is.
`In the future, a technician or a vehicle
`manufacturer could take a look under the hood
`remotely to identify and diagnose problems,
`determine whether you can keep driving, or
`recommend obtaining service.
