`trolled audio processor (125) (such as a DSP), a broad-
`cast radio tuner (126) (such as an AM/FM tuner), and an
`audio amplifier (130). Plastic optical fibre (27) intercon-
`nects the front control unit (25) and the audio communi-
`cation unit (26) which each include respective optical
`transceivers (92,94,122,134)

`Description
`
`lular phone, CDJ, navigation, and remote control panels
`such as a steering wheel control (SWC), anda rear seat
`control. In one example, the implementation of such a
`system required 7 modules and 31 wires. By packaging
`the HMI! and media player together with the tuner and
`amplifier, a savings of one module and four wires is pos-
`sible. However, overall power management andlarge
`heat generation create other problems which may also
`limit audio performance.
`[0007]
`In one aspect of the invention, a vehicle
`information, communication, and entertainment system
`provides mobile operation in a vehicle. A front control
`unit provides an open,
`scalable architecture and
`includes a control motherboard with a complex instruc-
`tion set processor and a video processor board with a
`graphics display driver. The front control unit further
`includes user input elements coupled to the complex
`instruction set processor and a graphics display cou-
`pled to the graphics display driver for providing a
`human-machine interface of the system for a user (i.e.,
`driver or passenger) of the vehicle. An audio communi-
`cation unit is located remotely from the front controlunit
`and provides an open, scalable architecture. The audio
`communication unit includes a digitally-controlled audio
`processor, a broadcast radio tuner, and an audio ampli-
`fier with audio outputs for coupling to audio transducers.
`A plastic optical fibre interconnects the front control unit
`and the audio communication unit. The front controlunit

`
`The present invention relates in general to
`[0001]
`an open, scalable architecture for a vehicle information,
`communication, and entertainment system, and more
`specifically, to a personal computer-based vehicle sys-
`tem with a limited number of modules interconnected by
`plastic optical fibre wherein a complex instruction set
`processorwithin a front control unit achieves centralised
`control throughout the system.

`[0002]
`Prior
`automotive
`architectures have been comprised of a simple human-
`machine interface (HMI), such as a display and param-
`eter adjustment push buttons or knobs, and a media
`player, such as a tape deck or CD mechanism. An AM-
`FM tuner and an amplifier have been included in the
`same module as the HMI and media player, or have
`been included in a separate module. As the desire for
`more entertainment and communication features has
`increased (such as the demand for cellular phones,
`compact disc jockey (CDJ), voice recognition, and navi-
`gation functions), the new features have been incorpo-
`rated into the vehicle system by vertically integrating the
`new function by means of an analogue audio output
`provided to the amplifier and adding a digital control
`scheme. This control scheme employs low speed multi-
`plexing so that new modules can be remotely controlled
`within the system.
`[0003]§The process of adding new modules for each and audio communication unit each include respective
`
`30
`new feature,
`the reliance on analogue audio signal
`optical transceivers for multiplexing digital data signals
`processing, and the use of low speed multiplexing have

`The present
`invention has the advantage

`that an open, scalable architecture is achieved while

`using a reduced number of modules and interconnects.
`Furthermore, this new architecture achieves increased

`as rear seat audio and video entertainment, mayday,
`and wireless data communications for stock, weather,
`E-mail, traffic information, sports, headlines, and on-
`board and off-board navigation with dynamic traffic
`updates.
`The invention will now be described further,
`[0009]
`by way of example, with reference to the accompanying
`drawings,in which:
`
`Such a module expansion strategy and the
`[0004]
`vertical integration of analogue audio to one amplifier
`results in a closed architecture with a limited expansion
`path. Once a particular product is designed, the number
`of pins available at the power amplifiers input connector
`limits further system expansion. In addition, such a sys-
`tem has a short lifetime and is not adaptable to new
`entertainmentfeatures such as digital audio and video,
`digital audio broadcasting (DAB), next generation com-
`pact disc, or digital versatile disc (DVD).

`present invention in greater detail.
`
`Figure 1 shows a prior art system employing
`[0010]
`a large number of modules, analogue audio signals,
`and a low-speed multiplex control architecture. An HM!
`and media player 10 provides analogue stereo audio
`signals to a tuner/audio processor/amplifier module 11
`over signal lines 12, which typically may consist of four
`wires comprising two twisted wire pairs. A voice recog-
`nition module 13 is connected to a microphone (not
`shown)for receiving and identifying spoken commands.
`Voice recognition module 13 synthesises voice signals
`to generate commands for the user by coupling ana-
`logue audio signals over signal lines 14 to module 11.
`Signal lines 14 preferably also comprise a twisted wire
`pair.
`A cellular phone module 15 comprises a
`[0011]
`transceiver which utilises module 11 in a hands-free
`mode by providing received analogue audio signals
`over a twisted pair signal line 16. Acompact disc jockey
`(CDJ) 17 provides analogue audio signals to module 11
`over signallines 18. A navigation unit 20 performs route
`calculation and route guidance based upon inputs of a
`current location and a desired location. Audible prompts
`are created by navigation module 20 and are provided
`to module 11 as analogue audio signals via signal lines
`21, again comprising a twisted wire pair.
`[00712]
`All of these modules are interconnected by a
`low speed multiplex communication system 22. Thus,
`the HMI
`in module 10 may be utilised by a driver or
`occupant of a vehicle to produce commands which
`affect operation of the media player, voice recognition
`system, cellular phone, CDJ, and navigation system, as
`well as tuner and audio processing functions of module
`11. Additional remote controls are provided by a steer-
`ing wheel control (SWC) switch panel 23 and a rear
`integrated control panel (RICP) 24, both of which are
`coupled to multiplex system 22. Depending upon the
`specifics of
`the multiplex system which may be
`employed, from 3 to 5 wires are required forimplement-
`ing the multiplex system. Thus, the architecture of Fig-
`ure 1 requires a large number of wires within the vehicle
`to interconnect the large number of separate modules.
`Furthermore, additional functions can be added to the
`system only with great difficulty and at greatexpense.
`[0013]
`The present invention takes advantage of a
`complex instruction set processor and plastic optical
`fibre communications to achieve the novel architecture
`shownin Figure 2. A front control unit (FCU) 25 includes
`an HMI, a media player, a complex instruction set proc-
`essor such as a Intel Pentium x86 type processor, a
`voice recognition function, and a navigation function.
`FCU 25 is coupled to an audio communication unit
`(ACU) 26 by a plastic opticalfibre 27. ACU 26 includes
`a broadcast tuner (such as AM/FM), an amplifier, acel-
`lular phone transceiver, and a global positioning system
`(GPS)
`receiver. This architecture also supports an
`optional compact disc jockey (CDJ) 28 as a third module

`optical fibre 29 and to FCU 25by plastic opticalfibre 30,
`resulting in a plastic optical ring.
`[0014]
`The network of Figure 2 achieves centralised
`control via one main scalable processor, preferably an
`X86 type of processor, for running all system applica-
`tions and thus eliminating many of the distributed proc-
`essor functions of the multiple processor system of
`Figure 1. Plastic optical fibre is utilised to perform data
`and control multiplexing including transmission of digital
`audio and video signals. A plastic optical network is
`preferably implemented using a network protocol such
`as the Media Oriented System Transport (MOST) proto-
`col.
`FCU 25 is shown in greater detail in Figure

`3. A motherboard 31 is connected to a video processor
`board 32 and an input/output board 33. Motherboard 31
`includes a complex instruction set processor 34 which
`may be comprised of an Intel Celleron processor, for
`example, and which is connected to a support chip 35
`which may preferably be comprised of an Intel banister
`bridge support chip. The support chip includes a DRAM
`memory controller 36 for controlling a DRAM memory
`37, Support chip 35 includes an IDE controller 38 for
`interfacing with a compact Flash drive 40 and a
`DVD/CD-ROMdrive 41. Compact Flash drive 40is pref-
`erably an IDE/ATA drive and stores operating system
`and application software for the information, communi-
`cation, and entertainment system. Drive 41 is a data
`storage drive for removable media such as DVD-ROM
`or CD-ROM and may be used for providing application
`software or data software, such as a map database for
`a navigation system.
`[0016]
`A clock oscillator 42 is connected to proces-
`sor 34 and support chip 35for providing timing signals.
`A basic input/output system (BIOS) chip 43 is con-
`nected to support chip 35 and provides boot-up and
`BIOS input/output instructions used during processor
`operation. A universal serial bus (USB) interface 44 is
`connected to a pair of physical layer output circuits 45
`and 46 which may be connected to USB peripheral
`expansion devices as desired.
`[0017]
`Support chip 35 further includes a peripheral
`component interconnect (PCI) bus interface which is
`connected to a PCI expansion slot 48. Expansion slot
`48 receives a PCI card connector 50 contained on video
`processor board 32to interconnect boards 31 and 32.
`[0018]
`Support chip 35 also includes an industry
`standard architecture (ISA) expansion bus interface 51
`connected to an ISA expansion slot 52 and to a multi-
`0 chip 53. Multi-l/O chip 53 performs peripheral com-
`munication handling for serial ports, parallel ports, infra-
`red communication (such as IrDA, the standard of the
`Infrared Data Association), and other standard I/O pro-
`tocols. Multi-l/O chip 53 may be comprised of an NS
`87308 chip manufactured by National Semiconductor,
`for example. A physical layer circuit block 54 connects
`multi-l/O chip 53 with serial ports COM1 and COM2.

`available from Texas Instruments, for example) which is
`connected to PCMCIA connectors A and B.
`[0020]
`A universal asynchronous receiver-transmit-
`ter (UART) chip 60 is connected to a connector 61 and
`interfaces via the ISA bus.
`[0021]
`Although various resources are shown on
`motherboard 31, not all are necessarily used in any par-
`ticular embodimentof the invention. For example, serial
`port COM2, PCMCIA connectors A and B, USB expan-
`sion connectors 45 and 46, UART connector 61, and
`ISA expansion slot 52 are not shown as being used in
`the embodiment shown in Figure 3. However, these
`resources are available for scalable expansion of fea-
`tures and capabilities of the information, communica-
`tion, and entertainment system.
`[0022]
`Serial port COM1 is connected to a serial
`port connector 65 of input/output board 33. A physical
`layer interface circuit 66 couples serial connector 65 to
`an input/output microprocessor 67, which may be com-
`prised of a Motorola 68HC912 microprocessor. Micro-
`processor 67 handles input of signals from user input
`elements and various vehicle sensors, and handles the
`operation of various power supplies within the informa-
`tion, communication, and entertainment system. The
`power management performed by microprocessor 67
`and input/output board 33 is described in greaterdetail
`in co-pending application U.S. serial number (199-
`0056), which is incorporated herein by reference.
`[0023]
`Microprocessor67is coupled to a keypad 68
`containing push button switches mounted to a control
`panel or bezel (not shown) of FCU 25. Various adjust-
`ment knobs or encoders 69 and 70 are also connected
`
`to microprocessor 67 for generating user input signals
`for controlling various functions of the system. The vari-
`ous functions controlled by user input elements 68-70
`may include radio tuning, audio volume, CDJ song
`selection, navigation system destination address input,
`cellular telephonedialling, and many others.
`[0024]
`Microprocessor 67 is also connected to a
`plurality of sensors 71 which may provide information
`used by the navigation application software, for exam-
`ple. The sensors could include odometer signals and a
`gear selector(reverse or forward selector) signalfor the
`purpose of monitoring vehicle motion by dead reckon-
`ing. Additionally, a gyroscope 72 may be mounted
`directly to input/output board 33 and connected to
`microprocessor 67 for monitoring vehicle movement.
`[0025]
`In keeping with the scalable architecture of
`the presentinvention, additional inputs and outputs may
`be coupled to processor 67 via a variety of input/output
`protocols. Thus, a UART interface 73 couples processor
`67 to a physical layer 74 and a UART connector 75. A
`pair of multiplex connectors 76 and 77 are coupled
`through physical layer 74 to microprocessor 67. A multi-
`
`plex application circuit 78 mayalso be includedif neces-
`sary for the multiplex protocol being used.
`(0026)
`A voltage regulator 80 provides power to
`microprocessor 67 and its support components.
`[0027]
`Microprocessor 67 controls a powercontrol-
`ler and regulator 81, which may be comprised of an
`LM2640 integrated circuit manufactured by national
`semiconductor, A variety of regulated voltages are pro-
`vided at voltage output pins 82 to be used by various
`components within the information, communication and
`entertainment system. A separate power supply 83 may
`be coupled to microprocessor 67 having the specialised
`purpose of providing power to a thin-film transistor
`(TFT) LCD display 85. Power supply 83 may be com-
`prised of a cold cathode florescent lamp power supply,
`for example.
`[0028]
`Video processor board 32 connects to the
`PCI bus of main control motherboard 31 and drives col-
`our graphics display 85. Video processor board 32
`includes a media processor 86 including a graphicsdis-
`play driver and means for performing various video
`encoding and decoding functions. Media processor 86
`may be comprised of an MPACT2 media processor
`made by Chromatic Research, for example. Media proc-
`essor 86 includes a memory interface 87 connected to
`DRAM 88 and a Flash BIOS 89. A PCI interface 90 is
`coupled to expansion connector 50.
`A_ peripheral
`input/output interface 91 is coupled to a MOSTtrans-
`ceiver 92. MOSTtransceiver 92 may be comprised of
`an O0S8104 network transceiver integrated circuit avail-
`able from OASIS Silicon Systems AG. A MOST connec-
`tor 93 connects to plastic optical fibre 27 which is
`coupled to ACU 26. A second MOSTtransceiver 94 is
`coupled to the PCI bus of video processor board 32 and
`also allows main processor 34 to communicate with the
`MOSTnetwork via MOST connector 95 andplastic opti-
`calfibre 30.
`
`The video graphics display driver of media
`[0029]
`processor 86 provides a VGA output 96 which is cou-
`pled to graphics display 85. Actual video data may be
`provided via PCI connector 50 from control mother-
`board 31, or may be provided by other sources commu-
`nicating with media processor 86 such as a TV tuner
`100 and a video decoder 101. Thus, broadcast televi-
`sion signals may be received by an antenna 102, with
`TV tuner 100 producing an NTSC video output 103
`which is coupled to video decoder 101. An analogue
`audio output may be provided directly to audio commu-
`nications unit 26 via an analogue audioline output 104.
`Alternatively, the TV audio output could bedigitised and
`provided digitally to ACU 26 via MOSTtransceiver and
`plastic optical fibre from video processor board 32.
`[0030]
`Video decoder 101 may be comprised of a
`programmable gate array 105 and a video input proces-
`sor 106, which may be comprised of an SAA7111A
`enhanced video processor available from Philips Semi-
`conductors. Video decoder 101 decodes NTSC video
`
`from TV tuner 100 and produces a digital video output
