Next, the operation will be described.

The navigation device 1 of this embodiment calls the destination of the moving target by using the wireless telephone function, receives address data or latitude / longitude data as the moving target position information from the destination, and performs navigation processing. It has its characteristics.

That is, in order to use the navigation device 1 to perform the navigation process, the user first needs to use the navigation device 1 to perform the calling process for making a call to the destination of the movement target. Yes, when a call is connected to the other party, necessary data is received from the other party and the data reception / navigation processing is performed to perform the navigation processing.

The calling process and the data reception / navigation process will be sequentially described below with reference to the flowcharts of FIGS. 7 and 8.

First, the calling process will be described with reference to FIG.

The user of the navigation device 1 turns on the power of the navigation device 1 in order to perform the calling process.
A word preset for causing the navigation device 1 to perform the calling process, for example, “telephone” or “off-hook” is generated toward the microphone 12.

When the power is turned on, the navigation device 1 performs a predetermined initialization process and then checks whether or not there is a voice input, as shown in FIG. 7 (step S
1) If voice is input through the microphone 12, it is checked whether the input voice is a call command (step S2).

Whether or not this calling command is issued is determined by the microphone 1
The voice (word) input from 2 is recognized by the voice recognition unit 23, and the recognition result output to the CPU 20 is searched by the CPU 20 in a dictionary for matching the recognized words and commands stored in the ROM 32. Determined by

If it is determined in step S2 that the command is not a call command, another process corresponding to the recognized word, for example,
Performs normal telephone call processing (step S
3).

When it is determined in step S2 that the command is a calling command, the CPU 20 activates the wireless transmission / reception circuit 22,
The off-hook state is set, and a message requesting input of information regarding the other party, for example, "please have the other party" is generated from the speaker 24 via the voice output unit 25. This message is stored in advance in the ROM 32 for each process as described above.

When the above-mentioned message is generated, the user of the navigation device 1 can use voice within a predetermined time to identify the destination (destination information), such as a telephone number, abbreviated number or the name of the destination. To the microphone 12 and input.

After uttering the above message, the navigation device 1 waits for a voice input (step S
5) It is checked whether or not the other party can be identified by the voice (step S6).

That is, in the navigation device 1, when a voice is input, the voice recognition unit 23 recognizes the voice and the CP
Whether the destination is specified based on the recognized destination information of the U20, that is, whether the telephone number of the destination is recognized when the telephone number of the destination is input by voice, and the shortened number of the destination is voiced. When entered,
Whether or not the telephone number corresponding to the abbreviated number is registered in the telephone directory file in RAM31, and when the name of the other party is input by voice, the telephone number corresponding to the relevant name is registered in the telephone directory file in RAM31. Check if it has been done.

If the destination is not specified in step S6, the process returns to step S4 and the message for requesting the input of the destination information is uttered again.

When the destination is specified in step S6,
The telephone number of the specified destination is sent to the wireless transmission / reception circuit 22.
To call the other party (step S
7).

After that, when the other party makes a call by a normal call processing and the other party answers, so-called hands-free communication can be performed.

Next, the data reception / navigation process will be described with reference to FIG.

When receiving data, the user of the navigation device 1 sets a message preset to enter the data reception mode when the other party answers, for example,
Speak "data reception" or the like into the microphone 12.

When the other party answers the call after the calling process of FIG. 7 is completed, the navigation device 1 checks whether or not there is a voice input (step T1), and if there is a voice input, the voice recognizer 23 recognizes the voice. Then, it is checked whether the voice is a data reception command, that is, a command for receiving the movement target position information (step T2).

If the received data is not the data reception command in step T2, processing other than data reception is performed (step T2).
3).

At step T2, when the command is a data reception command, a message to be sent to the other party for data reception,
For example, utter "Please speak your address or latitude and longitude after the beeping sound" and output it through the voice output unit 25 and the speaker 24, and also through the wireless transmission / reception circuit 22 and the telephone antenna 21. And transmits it to the other party (step T4).

This message for data reception is RO
It is stored in the M32, and the CPU 20 reads it from the ROM 32, outputs it through the audio output unit 25 and the speaker 24, and transmits it through the wireless transmission / reception circuit 22.

When the correspondent of the other party's telephone hears this data receiving message and speaks the address or latitude / longitude,
The voice recognition unit 23 recognizes this voice.

That is, when the navigation device 1 outputs a message in step T4, it waits for a voice input from the other party (step T5), and if there is a voice input, recognizes the voice and recognizes the other party's position. Is recognized (step T6).

That is, the navigation device 1 recognizes the voice from the other party by the authenticity recognition section 23, and when it judges that it is the address or the latitude / longitude, identifies the position of the other party based on the address or the latitude / longitude. Then, the destination position and the self position are synthesized on the map information stored in the CD-ROM of the CD-ROM unit 33 (step T7).

At this time, when the latitude and longitude data is sent from the other party, the other party's position can be synthesized directly on the map information, but when the other party sends the address, C
The PU 20 converts the address data into latitude / longitude data based on the address / latitude / longitude data table of the RAM 31 and synthesizes the destination position on the map information. At this time, the map information corresponding to the latitude / longitude data of the destination is retrieved from the map information in the CD-ROM, and the destination position is synthesized on the map information.

Further, the self-position is received by the GPS receiving section 29 via the GPS antenna 28 by the signal from the communication satellite, and is analyzed by the CPU 20 based on the received signal. This self position is synthesized on the map information of the CD-ROM.

However, when the destination position and the self position cannot be combined on the same map information due to the scale of the map, even if a map combining the partner position and a map combining the self position are prepared separately. Alternatively, a map may be prepared in which only the destination positions are combined. Further, it is possible to adopt a map that can combine the scale of the map with both the destination position and the self position.
Furthermore, each of these maps is prepared and the navigation device 1
The map selected by the user's selection may be displayed on the display unit 8b in a display process described later, or the map near the partner position or the self position may be displayed on a split screen or window screen by dividing the screen or displaying a window. You may make it respectively display-output.

When the destination position is synthesized on the map information, the state of the slide portion 6 is checked. If the slide portion 6 is in the display state, that is, if the display portion 8b is not visible as shown in FIG. The section driving section 27 is driven to bring the slide section 6 into the display state, the synthesized map information is developed in the display data creating section 26, and displayed and output on the display section 8a (step T8).

Therefore, for example, as shown in FIG. 9, the display unit 8b displays the position of the user (indicated by a black triangle in FIG. 9) and the position of the other party (double in FIG. 9) on the map. (Displayed by a circle) is displayed and output, and the destination position, which is the movement target position, can be easily confirmed. As a result, easy-to-understand navigation can be performed, and the usability of the navigation device 1 can be improved.

When the destination position is recognized by latitude and longitude in step T7, the recognized latitude and longitude data of the destination is displayed in the latitude and longitude data fields provided in the telephone directory file of the RAM 31 as shown in FIG. As shown in, write (step T8).

Therefore, when moving to the same destination after the next time, the latitude data stored as the destination information in the telephone directory file of the RAM 31 is called without calling the destination and sending the destination information. Also, it is possible to perform navigation by synthesizing the destination position on the map based on the longitude data. As a result, the destination information can be effectively used, and the usability of the navigation device 1 can be improved.

In the above embodiment, the navigation is performed by sending the address or latitude / longitude as the destination information, but the destination information is not limited to this, and the destination position is described. You may have the sent map information transmitted.

FIGS. 10 and 11 are diagrams showing a second embodiment of the present invention. In this embodiment, a map information transmission request is made to the other party, and the self-position is added to the transmitted map information. It is to be combined and displayed for output. It should be noted that this embodiment is applied to the same navigation device 1 as the first embodiment, and in the description of this embodiment, the reference numerals used in the first embodiment will be used as they are.

In this embodiment, similarly to the above embodiment, when a call is made to the other party and the other party answers, it is checked whether or not there is a voice input as shown in FIG. 10 (step P1). If there is a voice input, it is checked whether it is a data reception command (step P2). When it is not a data reception command, other processing than the data reception processing is performed as in the above embodiment (step P3), and when it is a data reception command, a signal sound prompting the transmission of preset map information is output. (Step P4).

This signal sound is stored in advance in the ROM 32 as a signal for prompting the other party to transmit map information at the time of the data reception command. The CPU 20 reads this signal from the ROM 32 and drives the wireless transmission / reception circuit 22 to generate the signal sound. To send as.

When the signal tone is transmitted, it is checked whether map information data has been received from the other party (step P
5) When the data reception is completed, the received map information is stored in association with the telephone number of the destination in the telephone directory file of the RAM 31 as shown in FIG. 11 (step P6). At this time, when the destination position is given as latitude data and longitude data, the latitude data and longitude data of the destination position are written in the latitude data item and longitude data item of the telephone directory file.

When the writing of the data to the RAM 31 is completed, the position of the user is combined with the received map information (step P7), the slide unit 6 is brought into the display state, and then the received map information is displayed on the display unit 8b. Output (Step P
8).

Therefore, according to the present embodiment, the map information received from the other party is stored in the RAM 31 even if the CD-ROM unit 33 included in the navigation apparatus 1 of the above embodiment is not provided, and the map is stored. By displaying and outputting the information, it is possible to perform navigation by displaying a map in which the position of the other party is described. As a result, it is possible to perform a navigation process that allows the position of the other party to be easily confirmed as in the above, and to make the navigation device 1 small and inexpensive. Further, the map information stored in the RAM 31 can be searched by the telephone number and displayed and output on the display unit 8b when moving to the same destination after the next time, and the map information can be effectively used. .

Also, the current position of the self is transmitted to the other party,
As the map information, the map information describing the route from the current position of the user to the position of the other party may be transmitted.

FIG. 12 and FIG. 13 are diagrams showing a third embodiment of the present invention. In this embodiment, the data of the own position is transmitted to the other party, and a map information transmission request is made.
The transmitted map information is displayed and output as it is. It should be noted that this embodiment is also applicable to the same navigation device 1 as the first embodiment, and in the description of this embodiment, the reference numerals used in the first embodiment will be used as they are.

That is, as shown in FIG. 12, when a call is made to the other party and the other party answers in the same manner as in the above embodiment, it is checked whether or not there is a voice input (step Q).
1) If there is a voice input, it is checked whether it is a data transmission command (step Q2). When it is not a data transmission command, other processing than the data transmission processing is performed as in the above embodiment (step Q3). When it is a data transmission command, the preset position data of itself is transmitted and the map is also transmitted. A signal sound requesting transmission of information is output (step Q4).

That is, the navigation device 1 uses the GP
The self-position is detected by the signal from the communication satellite received through the S antenna 28 and the GPS receiving unit 29, and the data of the self-position, for example, the latitude data and the longitude data are transmitted to the partner as the wireless transmission / reception circuit 22 and for the telephone. While transmitting via the antenna 21, the signal sound previously stored in the ROM 32 as a map information reception request signal is transmitted to the other party.

When the signal sound of the self-position and the map information reception request is transmitted, it is checked whether or not the map information data is received from the other party (step Q5). When the data reception is completed, the received map information is FIG. 11 of the second embodiment
As shown in, the telephone number is stored in the telephone directory file of the RAM 31 in association with the telephone number of the other party (step Q6).
At this time, when the latitude data and the longitude data are given as the destination position, the latitude data and the longitude data of the destination position are written in the latitude data item and the longitude data item of the telephone directory file.

This map information is such that the other party's telephone synthesizes the other party's position and its own position on the map information based on the own position transmitted by the navigation device 1, and at the same time, the other party's position changes to the other party's position. By synthesizing the route up to the map information, it is created as shown in FIG. 13, for example.

Note that, in FIG. 13, the self-position is indicated by a black triangle, and the destination position is indicated by a double circle. A solid line extending from the self position to the partner position indicates the route.
Note that this route may be displayed at the same time as a route that is easy to understand, the route with the shortest distance, or the like, or may be requested from various routes when the navigation device 1 requests map information.

When the writing of the map information into the RAM 31 of the data is completed, the slide portion 6 is brought into the display state, and the received map information is displayed and output on the display portion 8b (step Q7).

Therefore, according to the present embodiment, the navigation device 1 can receive the map information received from the other party even if the navigation device 1 does not include the CD-ROM section 33 included in the navigation device 1 of the first embodiment. The navigation similar to the above can be performed by storing in the RAM 31 and displaying and outputting the map information. As a result, it is possible to perform a navigation process that allows the position of the other party to be easily confirmed as in the above, and to make the navigation device 1 small and inexpensive. Further, since the map information of the present embodiment describes the route from the self position to the destination position, the route from the self position to the destination position can be easily known, and the navigation is easier to understand. It can be performed.
