The telephone directory storage means stores telephone directory data that can be used during a hands-free call using a mobile phone. The phone book management means acquires the phone book data stored in the mobile phone via the communication means, and stores the acquired phone book data in the phone book storage means. According to such a configuration, the same data as the phone book data stored in the mobile phone is stored in the phone book storage means. Therefore, when a hands-free call using a mobile phone is performed, the phone book data is read from the phone book storage means, so that the user uses the same phone book data stored in the mobile phone that the user has. It becomes possible to do.

  Further, when a communication connection is made simultaneously with a plurality of mobile phones via the communication means, the hands-free means executes a hands-free call using any of the plurality of mobile phones. The phone book management means acquires the phone book data stored in each of the plurality of mobile phones, and stores the integrated phone book data obtained by integrating (merging) the acquired phone book data in the phone book storage means. To do. In this way, the phone book storage means stores integrated phone book data that covers data such as phone numbers included in each phone book data stored in a plurality of mobile phones. Therefore, for example, when a hands-free call using any one of a plurality of mobile phones owned by the same user is performed, the integrated phone book data is read from the phone book storage unit, so that the user can It is possible to use all the phone book data at the same time without performing an operation of switching data. Thus, according to the present means, the convenience of the phone book data corresponding to the external mobile phone connected via the communication means can be improved.

  When one mobile phone is connected for communication, the user can use the phone book of the mobile phone that is connected for communication, but can use the phone book of the mobile phone that is not connected for communication. The nature is low. On the other hand, when a plurality of mobile phones are connected for communication at the same time, the user is likely to use a telephone directory of the plurality of mobile phones connected for communication. Therefore, particularly when a plurality of mobile phones are connected for communication at the same time, the effect obtained by integrating a plurality of phone book data is high.

  Now, when the user gets on the vehicle with the BT telephone 10, the connection between the hands-free device 2 and the BT telephone 10 is established. Thereafter, when the user performs a predetermined operation, the BT telephone 10 possessed by the user is registered as a target for hands-free communication (call) in the hands-free device 2. Each process shown in FIG. 3 is executed after such registration is completed. In the following explanation, for example, six telephones A to E are registered.

<For Single-HFP>
The telephone directory function in the case where a HFP is connected to one BT telephone 10 to be a target (use target) of a hands-free call (Single-HFP) is as follows. First, when a predetermined operation is performed by the user, a list display screen of telephones A to E registered in advance is displayed (see FIG. 4A). In this case, on the list display screen, registered telephone display units 31a to 31e representing the six telephones A to E, an [OK] button 32, and the like are displayed as touch switches. The registered telephone display units 31a to 31e are operated when selecting a telephone to be connected to the HFP, and the [OK] button 32 is operated when executing the HFP connection. It should be noted that a plurality of registered telephone display units 31a to 31c can be selected simultaneously (collective selection).

  In a state where the list display screen is displayed, when any of the registered telephone display units 31a to 31e is touched (selected) and the [OK] button 32 is touched, the touched registered telephone display units 31a to 31a are displayed. The HFP connection with the telephone corresponding to 31e is started, and a screen indicating that the connection is in progress is displayed. In this case, as shown in FIG. 4A, the [OK] button 32 is touched after the registered telephone display unit 31a is touched. Therefore, the HFP connection with the telephone A is started, and a screen indicating that the telephone A is being connected is displayed (see FIG. 4B). Thereafter, when the HFP connection with the telephone A is completed, a screen indicating that the connection is completed is displayed (see FIG. 4C).

  At this time, the following determination is made according to the flowchart of FIG. That is, since any one of the registered telephone display units 31a to 31e is touched and the [OK] button 32 is touched, “YES” is determined in the step S1, and the process proceeds to a step S2. In this case, since the selected telephone is one (telephone A), “NO” is determined in the step S2, and the process proceeds to the step S3. Furthermore, in this case, since the telephones (B to E) different from the telephone A are not already selected (connected), “NO” is determined in the step S3, and the process proceeds to the step S4.

  After the HFP connection is completed as described above, a top screen related to the hands-free function is displayed by performing a predetermined operation by the user (see FIG. 5A). On the top screen, a telephone name display field 41, a destination display field 42, and the like are displayed, and as a touch switch, a key input unit 43, a [phone book] button 44, a [connect] button 45, and a [call] button 46 are displayed. , [Return] button 47 and the like are provided.

  In the telephone name display field 41, characters representing the BT telephone 10 currently used are displayed. In this case, the characters “telephone A” representing the telephone A which is the BT telephone 10 connected by HFP are displayed. In the transmission destination display field 42, the telephone number of the transmission destination is displayed. The key input unit 43 is an array of various keys, and is used when inputting a destination telephone number or when manually creating telephone book data (manually). The [phone book] button 44 is for using the phone book function. [Connect] button 45 is used to switch the telephone set to be used. [Send] button 46 is for starting a call to the telephone number displayed in the destination display field 42. [Return] button 47 is used to return the display screen to the previous screen.

  If the [Phonebook] button 44 is touched, “YES” is determined in the step S4, and the process proceeds to a step S5. In step S5, a message is displayed to confirm to the user whether or not the telephone directory data stored in the BT telephone 10 (telephone A) may be transferred to the hands-free device 2 (FIG. 5B). )reference). FIG. 5B is a table of messages in the case where there is no telephone book data in the telephone book data storage area 22 for the BT telephone corresponding to the connected BT telephone 10 (phone A) (the telephone book data is empty). It is an example. If the phone book data is not empty, a message for confirming whether or not the phone book data can be updated (overwritten, added, etc.) is displayed (not shown).

  Here, when [No] is selected, the processing ends without transferring the telephone directory data. On the other hand, when [Yes] is selected, the telephone book data is transferred from the BT telephone 10 (telephone A) to the telephone book data storage area 22 for the BT telephone. At that time, a screen display indicating that the phone book data is being transferred is displayed (see FIG. 5C). When the transfer of the phone book data is completed, a list of phone book data stored in the BT telephone phone book data storage area 22 is displayed (see FIG. 5D). In the phone book data list, registered names are displayed in alphabetical order. When the user intends to use the telephone A, the user can perform a call operation to the telephone number associated with the registered name simply by selecting a desired registered name from the list by a touch operation. After executing step S5, the process returns to step S1.

<For Dual-HFP>
The telephone directory function in the case where the HFP is connected to a plurality of BT telephones 10 to be the target (use target) of the hands-free call (Dual-HFP) is as follows. The following two cases can be considered as the case of Dual-HFP.

(1) First case In the first case, after one telephone is selected on the device connection screen (telephone selection screen) and the HFP is connected to the one telephone, the device connection screen is displayed again. This is a case in which another telephone is selected and the HFP is connected to the other telephone. Hereinafter, details of the first case will be described. Here, it is assumed that the HFP is already connected to one BT telephone 10 (telephone A) and the telephone directory data has been transferred.

  In a state where the list display screen is displayed, when any of the registered telephone display units 31a to 31e is touched (selected) and the [OK] button 32 is touched, the touched registered telephone display units 31a to 31a are displayed. The HFP connection with the telephone corresponding to 31e is started, and a screen indicating that the connection is in progress is displayed. In this case, as shown in FIG. 6A, the registered telephone display unit 31c is touched and then the [OK] button 32 is touched. Therefore, the HFP connection with the telephone C is started, and a screen indicating that the telephone C is being connected is displayed (see FIG. 6B). Thereafter, when the HFP connection with the telephone C is completed, a screen indicating that the connection is completed is displayed (see FIG. 6C).

  At this time, the following determination is made according to the flowchart of FIG. That is, since any one of the registered telephone display units 31a to 31e is touched and the [OK] button 32 is touched, “YES” is determined in the step S1, and the process proceeds to a step S2. In this case, since the selected telephone is one (telephone C), “NO” is determined in the step S2, and the process proceeds to the step S3. However, in this case, since the BT telephone 10 (telephone A) different from the telephone C is already selected (connected), “YES” is determined in the step S3, and the process proceeds to the step S6.

  Thereafter, by touching the [Connect] button 45 on the top screen, the telephone set to be used can be switched. In this case, when the telephone to be used is the telephone C, the following operation is performed. That is, as shown in FIG. 7A, when the [phonebook] button 44 is touched on the top screen, “YES” is determined in the step S6, and the process proceeds to the step S7. In step S7, a message is displayed to confirm to the user whether or not the telephone directory data stored in the BT telephone 10 (telephone C) may be transferred to the hands-free device 2 (FIG. 7B). )reference). The confirmation message is the same as that shown in FIG. Here, when [No] is selected, the processing ends without transferring the telephone directory data. On the other hand, when [Yes] is selected, the telephone directory data is transferred from the BT telephone 10 (telephone C) to the telephone directory data storage area 22 for the BT telephone. At that time, a screen display indicating that the phone book data is being transferred is displayed (see FIG. 7C). When the transfer of the phone book data ends, the process proceeds to step S8.

  In step S8, the telephone directory data of the telephone A and the telephone directory data of the telephone C transferred to the hands-free device 2 are integrated (merged). When integrating the phone book data, the process of combining duplicate data (the telephone numbers and registered names match) may be performed, or the process may not be performed. When the integration of the phone book data is completed, a list of integrated phone book data stored in the BT telephone phone book data storage area 22 is displayed (see FIG. 7D).

(2) Second Case The second case is a case where a plurality of telephones are selected at a time on the device connection screen (telephone selection screen) and the HFP is connected to the plurality of telephones. Hereinafter, details of the second case will be described.

  In a state where the list display screen is displayed, when any of the registered telephone display units 31a to 31e is touched (selected) and the [OK] button 32 is touched, the touched registered telephone display units 31a to 31a are displayed. The HFP connection with the telephone corresponding to 31e is started, and a screen indicating that the connection is in progress is displayed. In this case, as shown in FIG. 8A, the registered telephone display units 31a and 31c are touched and then the [OK] button 32 is touched. Therefore, the HFP connection is started between the telephones A and C, and a screen indicating that the telephones A and C are being connected is displayed (see FIG. 8B). Thereafter, when the HFP connection is completed between the telephones A and C, a screen indicating that the connection is completed is displayed (see FIG. 8C).

  At this time, the following determination is made according to the flowchart of FIG. That is, since any one of the registered telephone display units 31a to 31e is touched and the [OK] button 32 is touched, “YES” is determined in the step S1, and the process proceeds to a step S2. In this case, since two telephones are selected (phones A and C), “YES” is determined in the step S2, and the process proceeds to the step S6.

  Thereafter, by touching the [Connect] button 45 on the top screen, the telephone set to be used can be switched. In this case, the following operation is performed regardless of whether the telephone set to be used is the telephone set A or C. That is, as shown in FIG. 9A, when the [Phonebook] button 44 is touched on the top screen, “YES” is determined in the step S6, and the process proceeds to the step S7. In step S7, a message is displayed to confirm to the user whether or not the phone book data stored in the BT telephone 10 (phones A and C) may be transferred to the hands-free device 2 (FIG. 9). (See (b)). The confirmation message is the same as that shown in FIG. Here, when [No] is selected, the processing ends without transferring the telephone directory data. On the other hand, when [Yes] is selected, the phone book data is transferred from the BT telephone 10 (the telephones A and C) to the telephone book data storage area 22 for the BT telephone. At that time, a screen display indicating that the phone book data is being transferred is displayed (see FIG. 9C). When the transfer of the phone book data ends, the process proceeds to step S8.

  In step S8, the telephone directory data of the telephone A and the telephone directory data of the telephone C transferred to the hands-free device 2 are integrated (merged). When the integration of the phone book data is completed, a list of integrated phone book data stored in the BT telephone phone book data storage area 22 is displayed (see FIG. 9D).

  According to the above configuration, when an HFP is connected to one BT telephone 10 to be a target of a hands-free call (Single-HFP), the user performs a hands-free call using the BT telephone 10. At this time, the same data as the phone book data stored in the BT telephone 10 can be used. In addition, when a user connects an HFP to a plurality of BT telephones 10 to make a hands-free call (Dual-HFP), the user performs a hands-free telephone call using any of the BT telephones 10. Even in such a case, the integrated phone book data obtained by integrating the phone book data stored in the BT telephone 10 can be used. Accordingly, when the user has a plurality of BT telephones 10 and gets on the vehicle, the user can use all of the phone book data at the same time without performing the operation of switching each phone book data as in the prior art. It becomes. As described above, according to the present embodiment, it is possible to improve the convenience of the phone book data corresponding to the BT telephone 10 that is the target of the hands-free call.

In this way, the user can respond to the predetermined telephone from when the predetermined telephone is selected until it is actually connected, or when the connection is disconnected for some reason after being connected. Therefore, the convenience of the telephone directory function is further improved.
When the in-vehicle device 1 is equipped with a data communication module (DCM) having a function as an in-vehicle phone, when the phone book data stored in the connected BT phone 10 is transferred, the phone book The data and the telephone directory data of the in-vehicle telephone may be integrated.

In the description of the telephone directory function in Dual-HFP, the case where the HFP is connected to two BT telephones 10 has been described as an example. However, the HFP is connected to three or more BT telephones 10. The same applies to the case.
When the phone book data stored in the same BT telephone 10 is transferred to the hands-free device 2, all the data may be acquired every time, or only the updated data may be acquired. .

  Data to be integrated and managed in the case of Dual-HFP is not limited to phone book data, but may be outgoing call history data, incoming call history data, missed call history data, and the like. That is, when a plurality of BT telephones 10 are connected as Dual-HFP, in addition to or instead of the telephone directory data corresponding to each of the plurality of BT telephones 10, outgoing call history data, incoming call history data, and absence At least one of the incoming call history data may be integrated (merged). As a method of merging each data, the same method as the method of merging the phone book data described in the above embodiment can be used.

  The communication means for performing communication between the in-vehicle device and the external mobile phone is not limited to the BT interface unit. That is, the connection between the in-vehicle device and the external mobile phone is not limited to Bluetooth, and may be a short-range wireless communication of another method, or may be configured to be connected by wire. When the communication means on the in-vehicle device side is changed, the communication means on the external mobile phone side may be changed to one corresponding to the communication means on the in-vehicle device side to be adopted. At that time, the communication protocol for performing hands-free communication, transfer of telephone directory data, and the like may be appropriately changed.
