`Description
`
`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
`processor within a front control unit achieves centralised
`control throughout the system.
`system
`entertainment
`[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 HIV” 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
`new feature.
`the reliance on analogue audio signal
`processing. and the use of low speed multiplexing have
`led to several
`limitations and disadvantages. The
`expansion of the number of electronirs modules compli—
`cates electrical system interconnects, thereby decreas-
`ing reliability and adding weight and cost. Besides all
`the additional wiring. a large connector with many pine
`is required at the analogue audio power amplifiers input
`connection. thereby increasing the cost of the amplifier
`module.
`
`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 atthe power amplifier‘s inputconnector
`limits further system expansion. in addition, such a sys—
`tem has a short lifetime and is not adaptable to new
`entertainment features such as digital audio and video,
`digital aucflo broadcasting (DAB). next generation com-
`pact disc. or digital versatile disc (DVD).
`[0005]
`This prior art architecture requires the use of
`redundant hardware resources between modules in
`order to achieve compatibility with the analogue audio
`portion of the system. For example. digital-to-analogue
`converters at the outputs of separate CD player and
`CDJ modules result in unnecessary duplication.
`[0006]
`Currently.
`the module expansion strategy
`has reached a practical limit with separate modules for
`the AM-FM tunen'amplifier, HMl. voice recognition. cel-

`lular phone, CDJ, navigation, and remote control panels
`such as a steering wheel control (SWO), and a rear seat
`control. In one example. the implementation of such a
`system required ? 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 and large
`heat generation create other problems which may also
`limit audio performance.
`[000?]
`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 control unit
`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 from control unit
`and the audio communication unit. The from control unit
`
`and audio communication unit each include respective
`optical transceivers for multiplexing digital data signals
`and digital control signals over the plastic optical fibre.
`The complex instruction set processor maintains central
`control over operation of the system.
`[0008]
`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
`use of digital audio and digital signal processing while
`permitting integration of evolving multl—media,
`informa—
`tion. communication and entertainment features such
`as rear seat audio and video entertainment, mayday,
`and wireless data communications for stock, weather,
`E-mail, traffic information. sports, headlines. and one
`board and off-board navigation with dynamic traffic
`updates.

`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 HMI
`and media player 10 provides analogue stereo audio
`signals to a tunerfaudio processoo’ampiifier module 11
`over signal lines 12. which typically may consist of four
`wires comprising two twisted wire pairs. A voice recogm
`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 signai 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. A compact disc jockey
`(CDJ) 17 provides analogue audio signals to module 11
`over signal lines 18. A navigation unit 20 performs route
`calculation and route guidance based upon inputs of a
`currentlocation and adesired location. Audible prompts
`are created by navigation module 20 and are provided
`to module 1 1 as analogue audio signals via signal lines
`21. again comprising atvvisted wire pair.
`[0012]
`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 (SWO) switch panel 23 and a rear
`integrated control panel (FllCP) 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 for implement-
`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 great expense.
`[0013]
`The present invention takes advantage of a
`complex instruction set processor and plastic optical
`fibre communications to achieve the novel architecture
`shown in Figure 2. Afrontoontrol unit(FCU) 25 includes
`an HMI, a media player, a complex instruction set proc-
`essor such as a Intel Pentium x88 type processor, a
`voice recognition function. and a navigation function.
`FCU 25 is coupled to an audio communication unit
`(ACU) 26 by a plastic optical fibre 27. ACU 26 includes
`a broadcast tuner (such as AMIFM}. an amplifier. acel-
`lularphone transceiver. and aglobal positioning system
`(GPS)
`receiver. This architecture also supports an
`optional compact discjockey (CDJ}28as athird moduie

`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

`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
`3?. Support chip 35 includes an IDE controller 38 for
`interfacing with a compact Flash drive 40 and a
`DVDfCD-ROM drive 41. Compact Flash drive 40 is pref-
`erably an IDEIATA drive and stores operating system
`and application software for the infom'iation, 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.

`A clock oscillator 42 is connected to proces-
`sor 34 and support chip 35 for providing timing signals.
`A basic inputfoutput system (BIOS) chip 43 is con-
`nected to support chip 35 and provides boot~up and
`BIOS inputfoutput 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
`43 receives a PCI card connector 50 contained on video
`processor board 32 to interconnect boards 31 and 32.
`[0018]

`used by the navigation application software, for exam—
`ple. The sensors could include odometer signals and a
`gear selector (reverse or forward selector) signal for the
`purpose of monitoring vehicle motion by dead reckon-
`ing. Additionally, a gyroscope 72 may be mounted
`directly to inputrloutput board 33 and connected to

`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 36 such as a TV tuner

`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 28 via an analogue audio line output 104.

`Turning now to Figure 4. audio communica-
`tion unit 26 will be described in greater detail. An ACU
`microprocessor 120 performs ACU operations and
`operates under control of main processor 34 on control
`motherboard 31 in response to signals received over
`plastic optical fibre 27 through MOST connector 121
`and MOST transceiver 122. Transceiver 122 has an
`inter-integrated circuit ([20) serial bus which carries
`control information to processor 120 over a bus 123.
`[0034]
`Transceiver 122 also has an inter-lC sound
`(128] bus output which provides digital audio signals to
`an audio digital signal processor {DSP} 124 and to sec-
`ond digital signal processorlDSP) 125 through theirIES 25
`interfaces. DSP 124 also receives audio inputs from an
`AMlFMlFIDS tuner 126, a cellular telephone board 127.
`and from external analogue audio such as TV audio
`from TV tuner 100. Analogue inputs are digitised and
`then processed within DSP 124 generating two or four
`channeis of digital audio signals. The input from tuner
`126 maybe an intermediate frequency {IF} signal which
`is processed by DSP 124 to recover the original modu—
`lating audio signals.
`[0035]
`DSP 124 includes digital-to-analogue con-
`verters 123 for providing analogue audio signals over
`audio lines 129 to audio amplifier 130 having multiple
`channels for driving a plurality of loudspeakers 131.
`DSP 125 provides additional audio processing such as
`surround sound, Dolby digital, orcther audio effects and
`provides digital audio signals to a digital-to-analogue
`converter block 132. Analogue audio signals for these
`additional audio channels are provided to amplifier 130.
`DSP 125 may utilise an external memory such as
`SRAM 133.
`[0036]
`A MOST transceiver 134 coupled to MOST
`transceiver 122 over bus 123 provides additional inter—
`facing for cellular telephone board 127, GPS receiver
`board 135, and wireless data transceiver board 136.
`Digital data from these units are provided to the main
`control processor via the MOST network.
`[0037]
`An additional analogue audio input may be
`provided by a microphone 140 leg. for connection to
`the cellular telephone) via an analogue input 141 cou-
`pled to a codec 142 providing input audio signals to
`DSP 125.

`The foregoing system has provided an archi-
`tecture for a vehicle information, communication, and
`entertainment system which is highly efficient and
`which provides an open. scalable architecture for imple-
`menting various functions and features in avehicie. Due
`to limited power availability in mobile vehicles. prior
`architectures utilised reduced instruction set processors
`which consume less power. However, in such systems
`an open. scalable architecture has not been achieved
`and access to existing application software programs
`and operating systems has been quite limited. The seg-
`mentation of functions and components according to
`the present invention and the use of plastic optical fibre
`in a network ring have provided significant advantages
`unachievable according to the prior art. In addition. sys-
`tern expansion is also achievable by additional compo-
`nents in the plastic optical ring itself. Thus. additional
`remote control stations within the vehicle or additional
`video monitors may be located within the vehicle by
`adding these units to the optical ring.
