Of course, there are other elements constituting the arithmetic processing unit 10, but illustration of elements not related to the description of the present invention is omitted.

The CPU 11 executes an application program described later and is used for various calculations.
For example, the current position of the vehicle is calculated based on information from the sensor unit 30 and the GPS (Global Positioning System) signal receiving unit 50, and the map information necessary for display is read from the calculated current position information from the external storage device 20 and It displays on the display part 40 with a position.

  The storage device 12 is a readable / writable storage means for storing application programs for various functions of the navigation device 1, data necessary for the calculation, or unique information of the connected mobile phone 2. Here, the Flash ROM 12 is stored in the storage device 12. An EPROM or the like having a function equivalent to this may be used.

  The RAM 13 is a temporary storage means that can be written / read to be used as a work area during arithmetic processing or to temporarily store various search data such as map data and telephone numbers.

The external storage device 20 is used for navigation processing of map data, road types, road data for route calculation such as nodes constituting the road data and link configuration information, coordinate values, telephone numbers and associated information, and facility information such as addresses. Necessary information is stored as a database.
The external storage device 20 is composed of one or a combination of a DVD drive 21 and a HDD (Hard Disk Drive) 22 into which a DVD (Digital Versatile Disk) 23 storing the information is inserted.

  The sensor unit 30 includes an azimuth sensor 31, a gyro 32, and a wheel speed sensor 33. The wheel speed sensor 33 detects a travel distance of the moving body by counting a pulse signal output with the rotation of the wheel by a counter 35. . This travel distance signal is sent to the arithmetic processing unit 10 via the internal bus 70.

The direction sensor 31 detects the direction of the moving body by detecting the magnetic field of the earth, and the gyro 32 uses an optical fiber gyroscope, a vibrating gyroscope, or the like, and detects the angle at which the moving body rotates.

Further, the CPU 11 detects whether or not an external device is connected by monitoring the change in the terminal voltage at the terminal 4b of the navigation device 1, and when the external device is connected, the internal bus 70 is connected to the CPU 11 as an interrupt signal. A signal is transmitted through the network.
As an external device other than the mobile phone, a palm-sized information device such as a palm computer is conceivable, and in this case as well, a phone book and an address are stored in a built-in memory.

Next, with reference to FIG. 3 (a) and FIG. 3 (b), processing from when a mobile phone is connected as a map display device until a point corresponding to the phone book data is registered will be described. explain.
First, in FIG. 3A, when the user connects the mobile phone 2 using the USB cable 3, the USB controller 80 detects the connection of the mobile phone 2 and notifies the CPU 11 as an interrupt signal via the internal bus 70. To do.
Upon receiving this interrupt signal, the CPU 11 starts USB interrupt processing at step 100 (hereinafter, “step” is expressed as “S”, but other steps are also expressed in the same manner).

When the interrupt process S100 is activated, the type of external device connected is first identified in S102. This requires an identification code assigned in advance to the connected device, and the type can be determined by the code.
Next, in S104, if the identification code is not that of the mobile phone (in the case of “N” in S104), the process exits from this process and shifts to another process corresponding to the identification code.

If the acquired identification code is the mobile phone 2 (in the case of “Y” in S104), a connection request is issued to the mobile phone 2 connected in S106, and the phone number of the connected mobile phone The initial connection process for acquiring unique information such as is performed.
After completion of the initial connection process in S106, the CPU 11 controls the USB controller 80 in S108 to communicate with the mobile phone 2 according to a communication flow to be described later, and acquire phone book data from the memory of the mobile phone 2.

  The telephone directory data acquired in S108 is temporarily stored in the RAM 13 of the navigation device 1 in S110, and after acquiring all the data, the mobile phone number of the information source, that is, the telephone number of the currently connected mobile phone and Acquired date and time information is added and stored in the flash ROM 12 as a telephone directory data list of the navigation device 1.

Next, in S112, it is confirmed whether or not the data has been updated. If the data has not been updated (in the case of “N” in S112), that is, if there is no change from the previous phonebook data, the phonebook is already stored in the FlashROM 12. Since data is stored, this interrupt processing S100 is terminated.
On the other hand, if there is a data update by checking whether or not the data has been updated in S112 (in the case of “Y” in S112), the process proceeds to the point registration process shown in FIG.
This point registration process is executed at least (1) when the mobile phone is first connected and the phone book data is stored in the navigation device 1 and (2) when there is a data change.

Next, the spot registration process S200 will be described with reference to FIG.
First, in S202, the registration date / time information is read from the phone book data stored in the FlashROM 12 by the above-described phone book acquisition process, and if the data is updated compared with the previous registration date, the telephone book data is read one by one. To do. Here, if the registration date is the same, the point registration process is not performed and the process is terminated.

When the telephone number is read out in S202, it is determined in S204 whether the telephone number of the fixed telephone is included.
Whether the telephone number is a fixed telephone number is determined based on whether the third digit number, which is a feature of a telephone number other than a fixed telephone such as a cellular phone, PHS, or IP telephone, is “0”.
That is, if the third digit number is “0” (in the case of “N” in S204), it is determined that the number is not a fixed telephone number, and the process proceeds to S206.

  In S206, it is determined whether or not all of the phone book data has been extracted. If there is still phone book data remaining in this step, the process returns to S202 to extract the next phone number from the phone book data. It is determined whether or not the extraction of the phone book data has been completed. If all the phone numbers in the phone book data are extracted and it is determined that all the phone numbers are not fixed phone numbers (“Y” in S206), this point registration processing is ended.

  If the extracted telephone number is a landline telephone number (in the case of “Y” in S204), it corresponds to the telephone number by referring to the point search database stored in the hard disk 22 in S208. A point search process for searching for a point is executed.

  After the process of S208, it is determined whether or not the data corresponding to the telephone number extracted in S210, that is, the coordinate value of the corresponding point exists. If there is corresponding data (in the case of “Y” in S210), after extracting the coordinate value of the corresponding point in S212, a process of reading the remaining telephone book data is executed.

Finally, in S214, the phone number, the coordinate value, and the spot information such as the spot name read in the process of S212 are stored in the FlashROM 12 as accompanying information.
If the telephone number corresponding to the point search database is not found in S210 (in the case of “N” in S210), the process returns to S206 to repeat the same process to confirm the next telephone book data. .

FIG. 4 shows the configuration of the point search database in the navigation device 1 of the present embodiment.
Here, 100 is a landline telephone number, 102 is a location name reading, 104 is a location name, for example, a unique location name for a location such as an individual name or a store name, and 106 is an address of the location (actually a prefecture, city, etc.) A code indicating a municipality) 108 indicates the longitude and latitude information of the point.

FIG. 5 shows an example of storing point registration data by executing a point registration process for registering a point in the navigation device using the phone book data of the mobile phone shown in FIG.
First, the basic information 200 will be described.
The order registered by the registration point ID 202 is stored as the basic information 200. Next, the registration point name 204, the coordinate value 206 of the registration point, and the telephone number 208 of the registration point are stored. These are the name, coordinate value, and telephone number registered in the search database of the navigation device 1. The

Further, on the map, an icon type 210 indicating a registration point and the number 212 of items of additional information registered in addition to the basic information 200 are stored.
Normally, 0 is stored in this additional information, but when location registration is performed by reading the phone book data, the number of information registered in the phone book data is recorded. In the example of FIG. 5, since the number of items of the added phone book data is two, that is, the mobile phone number and the image data, 2 is stored.

The contents of the additional information 300 are stored in the subsequent parts.
As the contents of the additional information 300, the telephone number and registration number of the mobile phone connected at the time of registration are stored as the additional information ID 302, and the additional information ID such as the mobile phone number, mail address, address, image data taken with the mobile phone, etc. A code indicating the type is stored in the additional information type 304.
When the type of the next additional information is image data, image information such as the data format 306 and size 308 is stored before the data body 310.

Next, an example of a communication flow between the navigation device and the mobile phone in the phone book acquisition process will be described with reference to FIG.
First, in S300, the navigation apparatus 1 outputs a request for setting switching to the data exchange mode for acquiring data held in the mobile phone including the phone book data to the mobile phone 2.

  If the mobile phone 2 can respond to this request, the mode setting is returned from the mobile phone and a setting OK response is sent back in S302. A connection request is sent to the mobile phone 2.

In response to this, when a response of connection OK is returned from the mobile phone 2, a request is made to the mobile phone 2 for an amount of data corresponding to the buffer size set in advance in S306.
Here, authentication processing is performed using an identification code of the location registration system, a password registered in the mobile phone, or the like.

  Further, since the cellular phone 2 returns predetermined data together with information (continuation or termination) indicating whether or not the telephone book data still remains in response to the request in S306, this is repeated until a data termination response is returned in S308. Continue processing.

When all data acquisition is completed, a disconnection request is output to the mobile phone 2 in S310, and when a disconnection OK response is returned from the mobile phone 2 in S312, a data exchange mode release request is transmitted in S314.
When the cancellation OK response is returned from the mobile phone 2 in S316, the present process is terminated.

  In the embodiment described above, the corresponding point is extracted at least by the telephone number of the fixed telephone included in the telephone directory data. However, when the telephone number of the fixed telephone is not included (for example, the mobile phone In the case where only the telephone number is registered), the point registration process is terminated as it is.

  On the other hand, it is checked whether the address data corresponding to the phone number of the mobile phone is stored in the phone book data of the mobile phone, and if it is stored, the point corresponding to the address data instead of the phone number If the location is identified from the address data in the phone book by searching from the search database (see Fig. 4), a new additional registration method can be adopted for the registered list of navigation. Needless to say.

In this case, a step of determining whether or not address data exists between S204 and S206 in FIG.
If the address data does not exist in this step, the process proceeds to S206 and the above-described process is executed. If the address data exists, the process proceeds to S208 and the above-described process is executed.

Next, an application example of the location registration data registered by the phone book data in the navigation device according to an embodiment of the present invention will be described.
When a map including points registered based on the phone book data is displayed, the icon specified by the icon type 210 is displayed at the registered points in the point registration data shown in FIG.

Here, when the cursor is brought near the registration point, only basic information is displayed in a balloon, and a message asking whether or not to display detailed data is displayed at the bottom of the screen.
Therefore, when the user desires the detailed display, a display for inquiring about the telephone number of the mobile phone used for registration is displayed. When a predetermined number is entered, the additional information ID ([FIG. 5] 302) is referred to. (Additional information) is displayed.

  In this example, only basic information is displayed regardless of who uses it, but registration data is managed for each mobile phone number used for location registration, and the corresponding mobile phone is connected. In such a case, an icon indicating a registration point or telephone book data may be displayed only when the telephone number of the corresponding mobile phone is input. In addition to the display on the map, these pieces of registered information may be referred to at the time of point search or destination setting.
