Embodiments of the present invention will be described below with reference to the accompanying drawings. Note that the embodiments described below are preferred specific examples of the present invention, and thus various technically preferable limitations are added.
In the following description, the present invention is not limited to these modes unless otherwise specified.

First, the configuration of the entire system of the apparatus according to the present embodiment will be described with reference to FIGS. In this example, the information processing system is installed in a moving body (here, an automobile). Specifically, as shown in FIG. 2, the automobile 100 accommodates a driving unit such as an internal combustion engine using gasoline or the like as a fuel, and drives the wheels with the driving unit to control the vehicle under user control. It can be moved. A monitor device 10 including a relatively small liquid crystal image display panel is mounted on a dashboard in the automobile 100. A controller 20 is connected to the monitor device 10, and various information obtained by the controller 20 is displayed on a monitor display unit 11 of the monitor device 10.
Is configured to be displayed. Various information processing devices are provided on the controller 20 with predetermined bus lines,
That is, they are connected via the in-vehicle information bus line B. The moving object to which the present invention is applied is not limited to an automobile, but may be various moving objects.

In FIG. 1, the devices connected to the controller 20 include a CD changer 30, a navigation device 40, a portable telephone connection unit 50,
Voice operation device 60 and amplifier 7 as audio device
0 (see FIG. 1) and four speaker devices 71, 72, 73, 74 (see FIG. 1) connected to the amplifier 70,
Further, a gateway 80 is prepared and connected in a predetermined order by the onboard information bus line. CD changer 3
The navigation device 40, the voice operation device 60, the amplifier 70, and the gateway 80 are installed in an empty space in the vehicle (for example, in a lower part of a dashboard, in a trunk, or the like). The mobile phone connection unit 50 is placed near a seat in the vehicle. Further, the speaker device 71,
72, 73, 74 are installed, for example, on the front left and right and rear left and right inside the vehicle.

Of these devices, devices other than the gateway 80 are vehicle-mounted devices which are installed in the vehicle 100 in advance and operate by power supply from the vehicle's battery power supply. In addition, a portable information processing device can be connected to this system via the on-board information bus line B. Here, an example in which a video camera 90 is connected is shown. The gateway 80 is
This is an electrical connection means for mutually connecting the in-vehicle information bus line B and the vehicle information bus line B0 of the automobile, and a specific configuration example thereof will be described later.

Next, referring to FIGS. 4 and 5, a specific system configuration relating to a main part will be described. First,
In FIG. 4, a monitor device 10 includes a video display unit 11 composed of a liquid crystal panel and the like, and a monitor speaker 12, displays a predetermined video (image) under the control of the controller 20, and emits a predetermined audio. . Monitor device 1
Numeral 0 includes a remote control signal receiving unit 13 for receiving (receiving) an infrared signal transmitted from the remote control device 14 and transmitting control information indicated by the received signal to the controller 20.

In this remote control device, the device code of an infrared signal transmitted based on the operation of a key disposed on the surface thereof is set to data corresponding to the device to be operated.

The controller 20 determines the category code of the remote control signal received by the remote control signal receiving unit 13, determines which device controls the information, and sends the information to the device connected via the onboard information bus line. A process for transferring control information is performed.

An on-board information bus line for connecting each device to the controller 20 is, for example, an IEEE (In)
A bus line according to a standard called IEEE 1394 certified by the Institute of Electrical and Electronics Engineers (IEEE) is used. This IEEE13
The bus line conforming to the standard 94 uses a connection cable 110 in which a power supply line 111, a data line 112, and a strobe line 113 are bundled and shielded, for example, as shown in FIG. The port section 120 to which the connection cable 110 is connected includes a power supply circuit 121 for outputting or inputting a DC low-voltage power supply to a power supply line 111 and a data input / output processing for inputting / outputting data transmitted on a data line 112. A processing unit 122;
Data transmitted on strobe line 113 (strobe)
And a strobe processing circuit 123 for performing the input / output processing of.

The strobe transmitted on the strobe line 123 is a signal that supplements the data transmitted on the data line 122. The exclusive OR of the data and the strobe is used to generate a data clock. is there. For example, as shown in FIG. 7, when the data transmitted on the data line 112 is in the state shown in FIG. 7A, the strobe becomes a signal which is inverted at a timing when the data does not change, as shown in FIG. 7B. By taking the exclusive OR of these two signals, the clock shown in FIG. 7C is generated on the receiving side.

In the IEEE 1394 bus line, when a bus line is connected to a port,
An address is automatically assigned to each connected device, and a destination of information transferred by the address is specified.

There are two types of transmission methods using an IEEE 1394 standard bus line: an asynchronous transfer mode, which is an asynchronous transfer mode, and an isochronous transfer mode, which is a real-time data transfer mode. Can be used depending on the type. Specifically, data such as control information of each device is transferred in packet units in the asynchronous transfer mode. FIG. 8 shows a packet transferred in the asynchronous transfer mode, in which an arbitration process for acquiring a bus line is performed from a port that desires data transfer. When the transfer right of the bus line is acquired by the arbitration process, a data packet is transmitted next. This data packet includes a header section and a data section. The header section contains information such as the address of the other party, its own address, and the size of the transfer data, and the data section contains the data to be actually transferred. Each data of the header part and the data part is loaded with a CRC code for error correction.

On the side receiving the data in the asynchronous transfer mode, the reception result of the transferred data is returned to the transmission source as an acknowledgment code which is a return code for reception confirmation. The above processing is repeatedly executed as long as there is data to be transferred.

For large-capacity information that needs to be transferred in real time, such as video information and audio information, data transfer is performed in the isochronous transfer mode. FIG. 9 shows a packet transferred in the isochronous transfer mode, in which an arbitration process for acquiring a pass line of the first channel (first channel) is executed from a port unit desiring data transfer. I do.
When the transfer right of the bus line is acquired by the arbitration process, a data packet is transmitted on the first channel, and arbitrary information such as video information is transferred by the data packet. When the packet of the first channel is completed, after a predetermined gap is opened, the arbitration of the second channel and the transfer of the data packet are performed, and thereafter, the transfer of the data required by the data packet is completed. , Transmission of an arbitrary number of channels is repeatedly executed. In this case, the isochronous transfer mode is
The transfer is executed prior to the asynchronous transfer mode, and the transfer mode is set in which the transfer band is guaranteed. In the isochronous transfer mode, there is no transmission of the return code for reception confirmation.

Since the respective devices are connected by the on-board information bus line configured as described above, various types of information can be transferred between arbitrary devices among the plurality of connected devices.

Next, details of the navigation device 40, the voice operation device 60, and the controller 20 of the system according to the present embodiment will be described with reference to FIGS.

In the voice operation device 60, the microphone 61

Data is transmitted in the asynchronous transfer mode via the information bus line B. Further, the host CPU 64 receives data from the interface unit 65 via the in-vehicle information bus line B, performs voice synthesis in accordance with the data,
By setting the destination ID in the corresponding information device,
Speech synthesis data is packet-transmitted in the asynchronous transfer mode.

The navigation device 40 includes a reception processing unit 41 for a signal transmitted from a GPS satellite, and transmits a signal received by the reception processing unit 41 to a host CP serving as a control unit.
In U42, a positioning calculation process is performed to detect the current position. When the positioning of the current position is performed, the host CPU 43 reads out road map data near the current position from the CD-ROM, which is a map disk, by the reading unit 42, and displays a road map from the road map data. Generate video data. It should be noted that depending on the operation mode, video data for performing various guidance displays other than the road map may be generated.

The navigation device 4 of the present embodiment
0 is VICS (Vehicle Information and Communicat)
The system is configured to receive a road traffic information communication system called an ion system, and includes an FM VICS tuner 46 as a receiving unit therefor. The VICS data (road traffic information) received by the tuner 46 is decoded by the reception processing unit 41.
If necessary, a process of adding the received road traffic information (road congestion state or the like) to the road map described above is performed.

The navigation device 40 transmits the generated video data for displaying a map or the like from the interface unit 44 to the interface unit 22 on the controller 20 side via the on-board information bus line B, and connects to the controller 20. A process of displaying an image on the image display unit 11 of the monitor device 10 is performed. In this case, the transmission of the video data on the in-vehicle information bus line is performed in an isochronous transfer mode which is a real-time transfer.

The on-vehicle information processing system according to the present embodiment is configured as described above. An example in which an operation is performed by the voice operation device 60 will be described with reference to the flowchart of FIG. In FIG. 11, first, in step ST1, when the user utters a voice command toward the microphone 61 of the voice operation device 60, the microphone 61 picks up the voice and outputs the voice signal via the A / D converter 62. It is sent to the host CPU 63. As a result, the host CPU 63 generates a command interrupt, and in step ST2, causes the DSP 64 to perform voice recognition, generates an AV / C command control signal, and transmits the control signal to the in-vehicle information bus line B.

In step ST3, the controller 20 determines whether or not the control signal transmitted via the bus line B is a control command for an information device to be connected to the on-board information bus line B. I do. If the control signal is a control command for an information device to be connected to the in-vehicle information bus line B, the process proceeds to step ST4. In ST4, the controller 20 determines whether or not the control command is a command for an information device connected to the in-vehicle information bus line B. If the control command is a command for an information device connected to the in-vehicle information bus line B, the controller of the interface unit of the information device interprets the control command according to an instruction from the controller 20 in step ST5. By transmitting a control signal to the information device, an operation corresponding to the control command is performed, and the process ends.

On the other hand, if the controller 20 determines in step ST4 that the control command is a command for an information device not connected to the in-vehicle information bus line B, the controller 20 proceeds to step ST6. ,
A signal indicating that execution is not possible is transmitted to the voice operation device 60, voice synthesis is performed by the voice operation device 60, and the voice is emitted from the monitor speaker 12 of the monitor device 10 based on the synthesized voice, or The monitor display unit 11 of the device 10 is caused to display that effect, and the process ends.

On the other hand, if the controller 20 determines in step ST3 that the control command is not a control command for an information device to be connected to the in-vehicle information bus line B, the process proceeds to step ST7. In ST7, controller 20 determines whether or not the control command is a control command for vehicle information bus line B0. When the controller 20 determines that the control command is a control command relating to the vehicle information bus line B0, the controller 20 determines in step ST8 that
A destination ID is set in the gateway 80, and a request command for information indicated by the control command is transmitted from the interface unit 22 in the asynchronous transfer mode. As a result, the gateway 80 has its memory 84
Is transmitted from the interface unit 85.

Thereafter, when data reception from the gateway 80 is completed in step ST9, the controller 20
Causes the voice operation device 60 to perform voice synthesis based on the data on the information transmitted from the gateway 80 in step ST10. Then, the voice operation device 60 sets the destination ID in the monitor device 10 and packet-transmits the voice-synthesized data in the asynchronous transfer mode (ST11). As a result, a voice synthesized by the voice synthesis is emitted from the monitor speaker 12 of the monitor device 10, and desired information is transmitted by voice.
The process ends. On the other hand, if the controller 20 determines in step ST7 that the control command is not a control command related to the vehicle information bus line B0, the controller 20 performs invalid command processing in step ST12, and finish.

Thus, for example, if the voice command is “tune name and play” of the CD changer, the control command from the voice operation device 60 is transmitted to the CD changer 30.
Is transmitted to the interface unit 36 of FIG. Thereby, C
In the D changer 30, when the physical layer 36c of the interface unit 36 receives this control command, the link layer 36b performs unpacking, error checking, and the like, and transmits the command to the controller 36a. Then, based on this control command, the controller 36a causes the CD magazine 31 to search for the selected song name and to reproduce the song. Next, the CD changer 30
The reproduction signal output from P34 is transmitted to the in-vehicle information bus line B in the isochronous transfer mode via the interface unit 36 based on the AV protocol. Thus, the controller 20 takes in the reproduced signal transmitted by the physical layer 22c of the interface unit 22, the link layer 22b performs an error check, and transmits the error signal to the controller 22a. As a result, the controller 22a converts the signal to baseband by the A / V decoder 21a of the audio reproduction processing unit 21, extracts the audio signal by the D / A converter 21b, and sends the audio signal to the monitor speaker 12 of the monitor device 10. As a result, the selected music is reproduced.

For example, when the voice command requests the "current vehicle speed", a corresponding control command is transmitted from the interface unit 65 of the voice operation device 60 to the on-board information bus line B in the asynchronous transfer mode. Transmitted. Accordingly, in the interface unit 85 of the gateway 80, when the physical layer 85c receives the control command, the corresponding data is read from the memory 84, which is the common access memory, and packetized in the link layer 85b. The transmission is performed in the asynchronous transfer mode from 85c. This data is received by the interface unit 65 of the voice operation device 60, and the DSP 64 reads out the baseband voice data corresponding to the data from the ROM 66, and again transmits the data from the interface unit 65 to the vehicle information bus line B in the isochronous transfer mode. To be transmitted. The baseband audio data is received by the interface unit 22 of the controller 20 and the monitor speaker 1 of the monitor device 10
From 2, a voice saying "It is XX km / h" is issued.

In this way, as shown in FIG. 12, a control command is transmitted as a data packet from the voice operation device 60 to the vehicle information bus line B in the asynchronous transfer mode by various voice commands. In the case of information equipment or vehicle information to be formed, the response data is transmitted from the gateway to the vehicle information bus line B.
Are transmitted in the isochronous transfer mode, are voice-synthesized by the voice operation device 60, and a response by voice is performed from the monitor speaker 12 of the monitor device 10.
That is, the control command is transmitted to the CD changer 30 as a data packet to the CD changer 30 by, for example, a voice command such as "How many cards are in the CD changer?" From 30, the response data is transmitted, so that a voice response of, for example, "10 sheets" or "Yes" is made. In the latter case, the specified song is further reproduced by the CD changer 30,
The reproduced signal is sent from the controller 20 to the monitor device 10.
Is reproduced by the monitor speaker 12.

Regarding the vehicle information, for example, a voice command such as "How many kilometers per hour are you now?", "How many liters of gasoline are you going to have?"
The control command is transmitted as a data packet to the gateway 80.
The response data is read from the memory 84 of the gateway 80 and transmitted from the interface unit 85, for example, "100 km / h", "the gasoline remaining amount is 20 liters", or " ○
It was 12,345 kilometers a day ".

Further, a control command is transmitted to the navigation device 40 as a data packet to the navigation device 40 by, for example, a voice command of “navigation mode” or “where is the current location?”, And response data is transmitted from the navigation device 40. By the transmission, for example, a voice response such as “the navigation mode has been set” or “before XX ward 6-chome XX” is performed. In the former case, the navigation device 40 further sets the navigation mode, and the monitor display section 11 of the monitor device 10 is switched to the navigation display.

Further, a control command is transmitted to the portable telephone connection unit 50 as a data packet to the portable telephone connection unit 50 by, for example, a voice command “call XX”.
From 0, by transmitting the response data, a voice response, for example, "Call OO03-1234-5678" is made. In this case, a calling signal is further transmitted from the mobile phone connection unit 50 to the mobile phone 51, and the mobile phone 51 performs a calling operation.

As described above, according to the system of the present embodiment, it is possible to operate the devices connected by the bus line in cooperation with each other, and to efficiently install the devices in the automobile only by connecting the bus line. Since each of the information devices operates by voice input to the voice operation device 60, there is no need to operate each of the information devices.
The operation of a plurality of information devices is easily performed.

The I used in the system of this embodiment
The bus line conforming to the standard called EEE1394 also supplies power as shown in FIG. 6, and as shown in FIG. Can be supplied via a bus line from the device for use. Further, by supplying power from the mobile phone connection unit 50, the mobile phone 51 can be operated without using a battery or the like built in the mobile phone 51.

In the above-described embodiment, the voice operating device 60 has the voice synthesizing function. However, the present invention is not limited to this. For example, the voice synthesizing function is built in another information device such as the navigation device 40. If it is, the voice synthesis function can be used via the bus line B.

In the above-described embodiment, the IEEE standard is used.
Although the bus line according to the standard called 1394 is used, the system may be constructed using a bus line of another standard. Furthermore, in the above-described embodiment, the present invention is applied to a system installed in an automobile, but it is needless to say that the present invention may be applied to an information processing system installed in another moving body.
