In the communication using the HID profile, information other than the operation content for the operation unit 61 of the portable terminal 6 can be appropriately exchanged between the HOST (navigation devices 1a to 4a) and the HID (mobile terminal 6). .

  The storage unit 63 is a non-volatile storage medium such as a flash memory. The storage unit 63 records the above-described database 7 and the like. FIG. 4 shows an example of the recording format of the database 7.

  As shown in this figure, the database 7 includes a plurality of history tables 71 and 72, and the history tables 71 and 72 respectively correspond to different types of navigation devices. Each history table 71 records a history of which function of the corresponding type of navigation device is selected and used. Specifically, one history table includes a sub table for each application (in the example of FIG. 4, a destination search application, a map display application), and each sub table includes the application of the corresponding type of navigation device. When using the function, a history of which function is selected and used among the functions provided by the application is recorded.

  In the example of FIG. 7, in the navigation device of model A, when using the destination search application, the function of searching the destination from the address has been used 58 times in the past, and the function of searching the destination from the telephone number has been used 17 times in the past. The function of searching for a destination from a map has been used six times in the past, and the function of searching for a current destination from a past destination (that is, a point set as a destination in the past) has been used once. . In each sub-table, the functions are sorted in descending order of use.

  The content of such a database 7 is updated by the operation of the navigation devices 1a to 4a and the mobile terminal 6, as will be described later.

When executing the CPU, the CPU reads information from the RAM, the ROM, and the storage unit 63, and stores the information in the RAM and the storage unit 63. Information is written to the wireless module 62 and communication is performed using the wireless module 62.

  Hereinafter, the operations performed by the navigation devices 1a to 4a and the portable terminal 6 for updating and using the database 7 will be described.

  First, an operation for updating the database 7 will be described. Here, it is assumed that the user 5 gets into one of the vehicles 1 to 3 (hereinafter referred to as the first vehicle) together with the portable terminal 6. At this time, when the navigation device (hereinafter referred to as the first navigation device, which corresponds to an example of the first in-vehicle device) mounted on the first vehicle and the portable terminal 6 are close to each other so that they can communicate with each other. The wireless connection based on the above HID profile is realized, and communication is performed with each other. Note that the registration of the mobile terminal 6 as the HID in the first navigation device as the HOST may be performed before the current user 5's boarding opportunity in the first vehicle, or the current boarding It may be done on an occasion.

  Then, the control circuit 17 of the first navigation device is constantly executing the function selection information transmission process as shown in FIG. 5 for updating the database 7, and the control circuit 64 of the portable terminal 6 is shown in FIG. The database update process as shown in is always executed.

  In the function selection information transmission process of FIG. 5, the control circuit 17 first waits at step 105 until wireless connection with the mobile terminal 6 by the HID profile is realized. When the wireless connection is realized, the model information is transmitted to the portable terminal 6 in step 110. The model information is information indicating the model of the own device (that is, the first navigation device). This model information is recorded in advance in the ROM of the control circuit 17 or the like.

  In the database update process of FIG. 6, the control circuit 64 of the portable terminal 6 first waits until wireless connection with the first navigation device by the HID profile is realized in step 205. When the wireless connection is realized, in step 210, the process waits until the model information is received from the first navigation device. When the model information is received, the model indicated by the model information is the model of the first navigation device that is currently wirelessly connected. To be identified.

  Subsequently, the control circuit 64 receives function selection information (described later) from the first navigation device (step 215) or disconnects the wireless connection with the first navigation device in the processes of steps 215 to 225. (Step 225).

  In addition, the control circuit 17 of the first navigation device determines whether a selection operation to be transmitted occurs in the processing of steps 115 to 125 following step 110 of FIG. Wait until the wireless connection is disconnected (step 125).

  Here, as a case where a selection operation to be transmitted occurs, for example, when using a destination search application, the user uses the operation unit 13 to “search for a destination from an address”, “from a telephone number” Applicable when one of the functions such as “Search destination”, “Search destination from map”, “Search current destination from past destination” is selected. To do.

  As another case in which a selection operation to be transmitted occurs, for example, when using a map display application, the user uses the operation unit 13 to display “a function for displaying a convenience store icon on a map”, “gas station” Any one or more of the functions such as “a function for displaying the icon of the game on the map”, “a function for displaying the icon of the restaurant on the map”, “a function of displaying the icon of the amusement park on the map”, etc. Applicable when selected.

  That is, “when a selection operation occurs” corresponds to a case where a predetermined function of a predetermined application is selected by a user operation. The predetermined application and the predetermined function are defined in advance in the function selection information transmission processing program of FIG.

  If a selection operation to be transmitted has occurred, the control circuit 17 determines that a selection operation to be transmitted has occurred in step 115, and subsequently creates function selection information and transmits it to the portable terminal 6 in step 120. The function selection information to be created is information indicating the function selected by the selection operation that is the object of the affirmative determination in step 115 and the application that provides the function. That is, the function selection information is information indicating which function of which application of the first navigation device the user 5 has selected and used.

  When the function selection information is transmitted in this way, the control circuit 64 of the portable terminal 6 determines that the function selection information has been received in step 215 of FIG. 6, and proceeds to step 220, where the received function selection information is stored in the database. 7 is reflected.

  Specifically, the history table of the model identified in the immediately preceding step 210 is identified from the database 7, the application sub-table indicated in the received function selection information is identified from the identified history table, and the identified application From the sub-table, information on the number of times of use corresponding to the function indicated in the received function selection information is specified, and the information on the specified number of times of use is increased by one time.

  In addition, after transmitting the function selection information in step 120, the control circuit 17 of the first navigation device again generates a selection operation to be transmitted in the processing in steps 115 to 125, or the mobile terminal 6 Wait until the wireless connection is disconnected. In addition, after reflecting the function selection information in the database 7 in Step 220, the control circuit 64 of the portable terminal 6 receives the function selection information from the first navigation device again in Steps 215 to 225, or Wait until the wireless connection with the first navigation device is disconnected.

  As described above, when the user of the portable terminal 6 uses the first navigation device in the first vehicle and selects and uses a specific function of a specific application, the function selection indicating the application and the selected function is selected. Information is transmitted from the first navigation device to the portable terminal 6. Then, the mobile terminal 6 reflects the received function selection information in the database 7.

  Since such a process is executed each time the user gets on each of the plurality of vehicles 1 to 3, the number of model tables in the database 7 increases as the user uses more vehicles. As the use frequency of the navigation device increases, the number of times each function of the database 7 is used increases. However, how to increase varies between functions depending on the preference of the user 5. For example, the number of functions that the user 5 does not use at all does not increase. Therefore, the more frequently the user uses the navigation device, the more accurately the database 7 reflects the user's preference. Therefore, by updating the database 7, the mobile terminal 6 can grasp which function the user 5 uses frequently for a predetermined application that should reflect the user's preference in each type of navigation device. It becomes possible to do.

  Here, an example will be described in which even the same user 5 shows a difference in the preference of the destination search function depending on the model. For example, it is assumed that the model A and model B have different operation procedures that the user has to perform on the operation unit 13 when searching for a destination from a map. For the user 5, the operation procedure in the function of searching the destination from the model A map is comfortable and fits his intuition, but the operation procedure in the function of searching the destination from the model B map is Suppose that it is cumbersome and does not fit intuition. In such a case, in the model A history table, the number of times of using the function for searching for a destination from the map increases, and in the model B history table, the number of times of using the function for searching for a destination from the map does not increase.

  Next, an operation for using the database 7 updated in this way will be described. Here, it is assumed that the user 5 has boarded the mobile terminal 6 in the first vehicle 4 (hereinafter referred to as a second vehicle) that has never been boarded. At this time, when the navigation device 4a (hereinafter referred to as the second navigation device) mounted on the second vehicle and the portable terminal 6 approach each other so that they can communicate with each other, the wireless connection based on the above HID profile is realized. Communicate with each other. In addition, registration of the portable terminal 6 as HID in the 2nd navigation apparatus as HOST shall be performed at the boarding opportunity of the user 5 this time for the 2nd vehicle, for example.

  And in order to utilize the database 7, the control circuit 64 of the portable terminal 6 is always performing the preference transmission process as shown in FIG. 7, and the control circuit 17 of the second navigation device is as shown in FIG. The preference reception process is always executed.

  In the preference transmission process of FIG. 7, the control circuit 64 of the mobile terminal 6 first waits at step 250 until wireless connection with the second navigation device by the HID profile is realized. When the wireless connection is realized, the process waits at step 260 until model information is received from the second navigation device.

  Further, in the preference reception process of FIG. 8, the control circuit 17 of the second navigation device first waits at step 130 until wireless connection with the mobile terminal 6 by the HID profile is realized. When the wireless connection is realized, subsequently, in step 135, the model information is transmitted to the portable terminal 6. Subsequently, in step 140, the process waits until user preference data is received from the portable terminal 6.

  In addition, when receiving the model information from the portable terminal 6, the control circuit 64 of the portable terminal 6 specifies that the model indicated by the model information is the model of the second navigation device that is currently wirelessly connected in Step 260. To do. In subsequent step 270, a history table corresponding to the identified model is extracted, user preference data for each application is created based on the extracted history table, and the created user preference data is transmitted to the second navigation device. .

  In addition, when the user preference data is received in step 140, the control circuit 17 of the second navigation device records the user preference data in a storage medium (RAM, storage medium of the map data acquisition unit 16) with a predetermined file name.

  Here, a method for creating user preference data for each application based on a history table of a certain model will be described. A sub-table is extracted for each application from the history table, and three functions up to the top three are used from each sub-table. As a result, the functions with the top three usages are extracted for each application. Then, a table is created for each application, and the three functions extracted for the application and the order of each function are recorded in association with each other in the table of each application. The table for each application thus created is used as user preference data for each application.

  Further, in order to reflect the user preference data created in the portable terminal 6 and recorded in the second navigation device in this way in the operation of the own device, the control circuit 17 of the second navigation device is shown in FIG. Execute the preference reflection process.

  The preference reflection process is started by being called from an application when a predetermined application is executed. The predetermined application is an application corresponding to the history table to be recorded in the database 7 (in the example of FIG. 4, a destination search application or a map display application). An instruction for calling the preference reflection process is incorporated.

  For example, the destination search application is an example of the predetermined application. During execution of the destination search application, the control circuit 17 calls and executes the preference reflection process to determine the destination search method.

  In this preference reflection process, first, in step 150, the default setting is used. As an example, as a method selection screen configuration (design) that allows the user to select a destination search method (corresponding to a predetermined function), a button for selecting “function” and a “function for searching a destination from a map” All of the buttons for selecting and the button for selecting “A function to search the current destination from past destinations” are displayed on the screen of the first page, and “Search destination by phone number” is displayed. The button for selecting “function to perform” is set to be displayed in the screen of the second page displayed through the page turning operation to the operation unit 13 by the user.

  Subsequently, in step 160, it is determined whether or not user preference data corresponding to the current caller application is recorded in the data of the predetermined file name. If not recorded, in step 180, the method selection screen is displayed on the image display device 12 in accordance with the set contents, that is, the default setting contents, and then the process is returned to the calling application.

  On the other hand, if recorded, in step 170, the configuration of the method selection screen is set in accordance with the user preference data corresponding to the application.

  For example, as user preference data corresponding to the application, the top three functions “a function for searching a destination from an address”, “a function for searching a destination from a telephone number”, and “a function for searching a destination from a map” ”Is recorded, among the above buttons, a button for selecting“ a function for searching a destination from an address ”, a button for selecting“ a function for searching a destination from a telephone number ”,“ Only a button for selecting “a function for searching a destination from a map” is set to be displayed in one screen of the first page.

  Further, for example, as user preference data corresponding to the application, the top three functions “function to search a destination from an address”, “function to search a destination from a telephone number”, and “search a destination from a map” If “Function” is recorded and “Function to search destination from address” is first, only the button for selecting “Function to search destination from address” is selected. It is set to be a screen that displays a map of the address on the background screen. The map screen of the background screen may be activated so that it can be easily scrolled by a user operation.

  In step 180 following step 170, the method selection screen is displayed on the image display device 12 in accordance with the setting in step 170, and then the process is returned to the calling application.

  Thus, after the portable terminal 6 is connected to the second navigation device, user preference data based on the history table corresponding to the model of the second navigation device in the database is created, and the created user preference data is stored in the first user preference data. 2 to the navigation device. Thereby, the second navigation device performs display such that the function indicated in the user preference data can be used preferentially over other functions.

  Therefore, even if the user is driving the second vehicle for the first time, if the user has previously used another navigation device of the same model as the second navigation device, the history is reflected in the database 7. Therefore, when the second navigation device adopts the user preference data transmitted from the database, an operation suitable for the user can be performed.

  Also, for example, as a tendency of the operation of the user 5, the destination search is usually performed by an address with a navigation device manufactured by company A, but the destination search is likely to be performed from a map display in the case of a navigation device manufactured by company B. Since this tendency is recorded in the database 7, it is possible to reflect the tendency of the user for each model of the navigation device.

  In the present embodiment, the control circuit 64 of the mobile terminal 6 functions as an example of a database update unit by executing the process in FIG. 6, and transmits user preference data by executing the process in FIG. 7. It functions as an example of means.

(Other embodiments)
As mentioned above, although embodiment of this invention was described, the scope of the present invention is not limited only to the said embodiment, The various form which can implement | achieve the function of each invention specific matter of this invention is included. It is.

  For example, the control circuit 64 of the mobile terminal 6 may add other information to the user preference data created and transmitted in step 270 of FIG. For example, if one of the top three most frequently used functions in the destination search application in the database 7 is “a function for searching for a current destination from a past destination”, the user preference of the destination search application As data, information on the next layer of information indicating “a function for searching a current destination from past destinations” is added. The information of the next layer is characteristic information (position, name, type, destination image and map around the destination) of a plurality of past destinations.

  In order to realize this, it is necessary for the database 7 to acquire and record characteristic information of a plurality of past destinations. Therefore, if the function for searching for the current destination from the past destinations is selected in step 120 of the process in FIG. 5, the control circuit 17 of the first navigation device selects a plurality of past destinations at that time. The feature information of the place is included in the function selection information and transmitted to the mobile terminal 6, and the control circuit 64 of the mobile terminal 6 uses the received feature information of the past destination in the “past purpose” in the history table of the model. It may be recorded in association with the “function for searching for the current destination from the location”.

  Moreover, in the said embodiment, the 1st navigation apparatuses 1a-3a perform the process shown in FIG. 5, and the 2nd navigation apparatus 4a performs a process as shown in FIG. 8, FIG. However, the first navigation devices 1a to 3a also execute the processing shown in FIGS. 8 and 9, and the second navigation device 4a also executes the processing shown in FIG. That is, each navigation apparatus 1a-4a performs the process of FIG.5, FIG.8, FIG.9. Therefore, the function selection information of the user 5 is transmitted to the mobile terminal 6 in any navigation device 1a to 4a, and the GUI adapted to the user based on the user preference data received from the mobile terminal 6 in any navigation device 1a to 4a. Display.

  Moreover, the portable terminal 6 may be used for operation of the navigation device. That is, the user 5 performs a desired operation on the mobile terminal 6, and the mobile terminal 6 transmits the operation itself to the navigation device of the wireless connection partner of the HID profile, and realizes an operation corresponding to the operation content on the navigation device side. It may be like this. By doing so, it is possible to provide a mechanism that can reduce user stress. In this case, the portion described as using the operation unit 13 of the navigation devices 1a to 4a is a portable device instead of the operation unit 13 when the navigation devices 1a to 4a and the portable terminal 6 are wirelessly connected with the HID profile. The operation unit 61 of the terminal 6 may be used.

  Moreover, in the said embodiment, whenever the user 5 performs operation which selects the predetermined function of a predetermined application with respect to a navigation apparatus, function selection information is transmitted to the portable terminal 6 from a navigation apparatus. . However, this is not necessarily the case. For example, when the user 5 gets off, a predetermined function of a predetermined application in a period from when the mobile terminal 6 and the navigation device are wirelessly connected to the present is selected at the timing when the parking brake of the vehicle is turned on. For all operations, function selection information may be created and transmitted to the mobile terminal 6 together.

  In the above embodiment, the mobile terminal 6 receives the function selection information, and creates and updates the database 7 based on the received function selection information. However, if it is difficult to create or update the database 7 on the portable terminal 6 due to a problem in processing capability, the portable terminal 6 may be connected to another device that can communicate with the portable terminal 6 (for example, a stationary personal computer that can communicate with Bluetooth). The function selection information may be reflected in the database 7 using a computer. In this case, when the mobile terminal 6 is wirelessly connected to the other device, the mobile terminal 6 transmits all the function selection information received from the navigation device so far to the other device, and the other device receives the received function. The database 7 is created or updated using the selection information, and the resulting database 7 is transmitted to the mobile terminal 6.

  Further, the wireless communication method between the mobile terminal 6 and the navigation devices 1a to 4a is not limited to the HID profile of Bluetooth, but may be another profile of Bluetooth or a communication method other than Bluetooth.

  Further, the second vehicle may not be a vehicle that the user 5 has never boarded. That is, even if the user 5 is a vehicle that has been used several times in the past, the operation stress of the navigation device of the vehicle may be eliminated using the database 7.

  In the above embodiment, the preference transmission process of FIG. 7 is related to whether or not the vehicle equipped with the second navigation device of the communication partner is the first vehicle that has never been used by the user 5 until now. Running. However, the preference transmission process of FIG. 7 is executed only when the vehicle equipped with the second navigation device of the communication partner is the first vehicle that has never been used by the user 5 until now. Also good. In order to determine whether or not the vehicle is the first vehicle, the control circuit 17 of the navigation devices 1a to 4a uniquely determines not only the model information but also its own device at step 110 in FIG. 5 and step 135 in FIG. The device ID to be identified is also transmitted to the mobile terminal 6, and the control circuit 64 of the mobile terminal 6 records the received device ID in the storage unit 63 in step 210 of FIG. 6 and step 260 of FIG. Following step 260, it is determined whether or not the device ID received this time is the first device ID. If it is the first device ID, then step 270 is executed. If it is not the first device ID, the processing of FIG. May be terminated.

  Note that the second navigation device of the communication partner is mounted in the example in which the preference transmission process of FIG. 7 is executed only when it is the first vehicle that has not been used by the user 5 until now. When the vehicle is a vehicle that has been used by the user 5 until now, the mobile terminal 6 transmits its own ID to the second navigation device. The user preference data received from 6 may be stored in association with the ID of the mobile terminal 6, and the user preference data corresponding to the received ID may be read out and used in the preference reflection process. By doing in this way, in the case of the vehicle which the user 5 has used until now, the communication amount between a navigation apparatus and the communication terminal 6 can be reduced.

  On the other hand, not only whether or not it is the first vehicle that the user 5 has never used until now, but in the example in which the preference transmission process of FIG. 7 is executed, the latest user preference data on the navigation device side. Can be received.

  Moreover, in the said embodiment, although the model information of the navigation apparatus of the connection other party of the portable terminal 6 is acquired from the said navigation apparatus, model information does not necessarily need to be acquired from a navigation apparatus. For example, the portable terminal 6 may identify which model of navigation device the mobile device is currently connected to based on the input of the model name of the navigation device to the operation unit 61.

  Further, the mobile terminal 6 may be configured to realize applications other than the applications described in the above embodiments, such as an application that operates as a mobile phone and an application that operates as a music player.

  Moreover, in the said embodiment, although the navigation apparatus is used as an example of a vehicle-mounted apparatus, the vehicle-mounted apparatus of this invention is not restricted to a navigation apparatus. For example, a map display device that does not have a navigation function may be used.

  In the above-described embodiment, the functions realized by the control circuit 17 of the navigation devices 1a to 4a and the control circuit 64 of the mobile terminal 6 executing programs are hardware (for example, circuits) having those functions. The configuration may be realized using a programmable FPGA).
