When a user inputs an operation detection signal from the touch operation input device 15 in response to a user operating a touch switch formed on the display screen, the touch operation input unit 7 outputs the operation detection signal to the control unit 2. When the operation detection signal is input from the touch operation input unit 7, the control unit 2 analyzes and processes the operation detection signal.

  When the mobile phone 21 having the BT communication function is inquired about HFP for performing hands-free communication standardized by the BT communication standard, or a function that can be provided by the mobile phone standardized by the BT communication standard. It corresponds to SDP for responding to. The mobile phone 21 is roughly classified from the viewpoint of the function of transferring telephone directory data. The mobile phone 21 includes a model that supports PBAP and OPP, and a model that does not support PBAP but supports OPP. There is. If the mobile phone 21 is a model that supports PBAP and OPP, when the SDP is connected to the in-vehicle hands-free device 1, the mobile phone 21 is compatible with PBAP and OPP. When the SDP is connected to the in-vehicle hands-free device 1, if the SB is connected to the in-vehicle hands-free device 1, the in-vehicle hands-free device 1 is notified. The in-vehicle hands-free device 1 is notified of a PBAP non-compliant notification indicating that the machine does not support PBAP but is compatible with OPP.

  Next, the operation of the above configuration will be described with reference to FIGS. Here, the description will be made on the assumption that HFP and PBAP or OPP can be simultaneously connected (multi-profile connection) between the mobile phone 21 and the in-vehicle handsfree device 1.

  In the in-vehicle hands-free device 1, the control unit 2, as shown in FIGS. 2 and 3, the mobile phone 21 exists in the BT communication area of the in-vehicle hands-free device 1, and the HFP is connected to the mobile phone 21. If it is determined that a connection request has occurred ("YES" in step S1), the HFP is connected to the mobile phone 21 by the BT interface unit 3 (step S2).

  Next, when the SLC connection completion notification is input from the BT interface unit 3, the control unit 2 outputs a PBAP compatibility confirmation request to the BT interface unit 3, connects the SDP to the mobile phone 21, and sends a function inquiry request. Transmission is performed from the BT interface unit 3 to the mobile phone 21 (step S3), and time measurement by a timer is started (step S4). Then, the control unit 2 determines whether or not a function inquiry response is notified from the mobile phone 21 (step S5), and whether or not the time measured by the timer has reached a specified time (time-up). It judges (step S6) and waits for the function inquiry response from the mobile telephone 21 to be notified.

  Here, when the mobile phone 21 connects the SDP with the in-vehicle hands-free device 1 and receives a function inquiry request transmitted from the in-vehicle hands-free device 1, the mobile phone 21 represents a function question indicating a function that can be provided by itself. A response is transmitted to the in-vehicle hands-free device 1. That is, if the mobile phone 21 is a model that supports PBAP and OPP, the mobile phone 21 notifies the in-vehicle handsfree device 1 of PBAP support notification, while the mobile phone 21 does not support PBAP. If the model is compatible with OPP, a PBAP incompatible notification is sent to the in-vehicle hands-free device 1.

  When the control unit 2 determines that the function inquiry response is notified from the mobile phone 21 before the time measured by the timer reaches the specified time (“YES” in step S5), the in-vehicle hands-free device 1 Is disconnected (step S7), and it is determined whether or not the function inquiry response notified from the mobile phone 21 is a PBAP compatible notification (step S8).

  When the control unit 2 determines that the function inquiry response notified from the mobile phone 21 is a PBAP support notification (“YES” in step S8), the control unit 2 sets “1” to the PBAP support flag ( In step S9), it is determined whether or not a phone book data transfer request has been generated (step S12), and the system waits for a phone book data transfer request to be generated. On the other hand, when the control unit 2 determines that the function inquiry response notified from the mobile phone 21 is not a PBAP compatible notification (“NO” in step S8), the control unit 2 sets “0” in the PBAP compatible flag (step S11). ), It is determined whether or not a transfer request for the phone book data has occurred (step S12), and the system waits for a transfer request for the phone book data.

  If the control unit 2 determines that the time measured by the timer has reached the specified time before the function inquiry response is notified from the mobile phone 21 ("YES" in step S6), the in-vehicle hands-free The SDP connected to the device 1 is disconnected (step S10), and in this case as well, “0” is set in the PBAP correspondence flag (step S11), and whether or not a transfer request for the phone book data has occurred. (Step S12), and waits for a phone book data transfer request to be generated.

  Now, when the user performs an operation to display the phone book menu selection screen, the control unit 2 displays the phone book menu selection screen shown in FIG. The phone book menu selection screen includes a transfer switch (Transfer Contacts) 16a representing transfer of phone book data, a new creation switch (New Contacts) 16b representing new creation of phone book data, and an edit switch (Editing representing phone book data editing). An Edit Contacts 16c and a delete switch 16d indicating deletion of the phone book data are formed.

  Here, when the control unit 2 determines that the user has operated the transfer switch 16a and determines that a transfer request for the phone book data has been generated ("YES" in step S12), the control unit 2 sets it at that time. The PBAP correspondence flag being set (step S13), whether or not the PBAP correspondence flag set at that time is “1”, that is, the mobile phone 21 that is currently connected to the HFP is notified of the PBAP correspondence It is determined whether or not the model is notified within the specified time (step S14).

  The control unit 2 is a model in which the PBAP support flag set at that time is “1”, that is, the mobile phone 21 that is currently connected to the HFP has notified the PBAP support within a specified time. If it is determined ("YES" in step S14), a PBAP connection request is generated to connect the PBAP to the mobile phone 21 that is currently connected to the HFP (step S15). Transfer of telephone directory data from the telephone 21 to the in-vehicle handsfree device 1 is started. At this time, the user does not need to operate the mobile phone 21.

  Next, the control unit 2 displays the PBAP transfer screen shown in FIG. 4B on the display device 14, and transfers the phone book data from the mobile phone 21 to the in-vehicle handsfree device 1 by connecting the PBAP. To the user. When the control unit 2 determines that the transfer of the phone book data from the mobile phone 21 to the in-vehicle hands-free device 1 is completed (“YES” in step S16), the control unit 2 is connected to the mobile phone 21. The PBAP that is present is disconnected (step S17), and the process returns.

  On the other hand, the control unit 2 indicates that the PBAP-compatible flag set at that time is “0”, that is, the mobile phone 21 that is currently connected to the HFP notifies the PBAP-compatible notification within a specified time. If the mobile phone 21 that is currently connected to the HFP generates an OPP connection request, the HFP is connected at that time. The OPP is connected to the mobile phone 21 that is currently connected (step S18), and the transfer of the phone book data from the mobile phone 21 to the in-vehicle handsfree device 1 is started. At this time, the user needs to operate the mobile phone 21 to specify phone book data to be transferred from the mobile phone 21 to the in-vehicle handsfree device 1.

  Next, the control unit 2 displays the OPP transfer screen shown in FIG. 4 (c) on the display device 14, and transfers the phone book data from the mobile phone 21 to the in-vehicle hands-free device 1 by connecting the OPP. To the user. When the control unit 2 determines that the transfer of the phone book data from the mobile phone 21 to the in-vehicle hands-free device 1 is completed (“YES” in step S19), the control unit 2 is connected to the mobile phone 21. The OPP that has been disconnected is disconnected (step S20), and the process returns.

  Through the processing described above, the in-vehicle hands-free device 1 determines whether or not the mobile phone 21 connected to the HFP is compatible with PBAP by connecting the SDP after connecting the HFP. When the PBAP correspondence notification is notified within the prescribed time, the PBAP correspondence flag is set to “1”, while in other cases (when the PBAP correspondence notification is not notified from the mobile phone 21 within the prescribed time and When the specified time has passed without receiving a PBAP correspondence notification from the mobile phone 21), the PBAP correspondence flag is set to “0”, and then the user performs an operation to instruct transfer of the phone book data. With reference to the PBAP-compatible flag, one of PBAP and OPP is selected and connected to the mobile phone 21. That is, in this case, by setting the PBAP support flag to “1” only for the models that have notified the PBAP support notification within the specified time, only the models that are highly likely to connect to the PBAP are subject to PBAP connection. Will be.

  In the above, the configuration for determining whether or not the function inquiry response notified from the mobile phone 21 is a PBAP compatible notification has been described, but the function inquiry response notified from the mobile phone 21 is a PBAP non-compatible notification. It may be determined whether or not. In this case, as shown in FIG. 5, the control unit 19 disconnects the SDP connected to the in-vehicle hands-free device 1 (step S7), and then the function inquiry response notified from the mobile phone 21 Is a PBAP non-compliant notification (step S21).

  Here, when the control unit 2 determines that the function inquiry response notified from the mobile phone 21 is a PBAP incompatible notification (“YES” in step S21), the control unit 2 sets “0” in the PBAP corresponding flag. (Step S22). On the other hand, when the control unit 2 determines that the function inquiry response notified from the mobile phone 21 is not a PBAP non-support notification (“NO” in step S21), the control unit 2 sets “1” in the PBAP support flag (step S21). If it is determined that the time measured by the timer has reached the specified time before the function inquiry response is notified from the mobile phone 21 ("YES" in step S6), the in-vehicle hands-free device 1 Is disconnected (step S10), and in this case as well, "1" is set to the PBAP correspondence flag (step S23).

  Through the processing described above, the in-vehicle hands-free device 1 determines whether or not the mobile phone 21 connected to the HFP is compatible with PBAP by connecting the SDP after connecting the HFP. When the PBAP non-compliant notification is notified within the specified time, the PBAP compatible flag is set to “0”. On the other hand (the PBAP non-compliant notification is not notified from the mobile phone 21 within the predetermined time) If the specified time has passed without notification of non-PBAP notification from the mobile phone 21), the PBAP support flag is set to “1”, and then the user performs an operation to instruct transfer of the phone book data. When this is done, the PBAP-compatible flag is referenced, and either PBAP or OPP is selected and connected to the mobile phone 21. In other words, in this case, by setting “1” in the PBAP support flag for a model other than the model that has notified the PBAP non-support notification within the specified time, for example, the PBAP is supported, but this is indicated in the specified time. Even models that are designed not to be notified or impossible to notify will be subject to PBAP connection.

  The above description is based on the assumption that HFP and PBAP or OPP can be simultaneously connected (multi-profile connection) between the mobile phone 21 and the in-vehicle hands-free device 1. When HFP and PBAP or OPP cannot be simultaneously connected to the in-vehicle hands-free device 1, the control unit 2 sets the PBAP support flag to “1” as shown in FIGS. Is determined (“YES” in step S14), the HFP connected to the mobile phone 21 at that time is temporarily disconnected (step S31), and the mobile phone 21 having the HFP temporarily disconnected PBAP is connected (step S15), and it is determined that the transfer of the phone book data from the mobile phone 21 to the in-vehicle hands-free device 1 has been completed ( After the PBAP connected to the mobile phone 21 is disconnected (step S17), the HFP is reconnected to the mobile phone 21 from which the PBAP has been disconnected (step S16: YES) S32), the state before the PBAP is connected is restored.

  Further, when the control unit 2 determines that the PBAP support flag is “0” (“NO” in step S14), the control unit 2 temporarily disconnects the HFP connected to the mobile phone 21 at that time ( When step S33) connects the OPP to the cellular phone 21 from which the HFP has been disconnected (step S18), and determines that the transfer of the phone book data from the cellular phone 21 to the in-vehicle handsfree device 1 has been completed ( After “YES” in step S19), after disconnecting the OPP connected to the mobile phone 21 (step S20), the HFP is reconnected to the mobile phone 21 from which the OPP has been disconnected (step S20). S34), the state before the OPP is connected is restored.

  When there are a plurality of mobile phones 21 that are permitted to connect to the in-vehicle hands-free device 1, the storage unit 5 associates the telephone information of each mobile phone 21 with the PBAP-compatible flag. The SDP is connected only at the beginning, and the phone information of the mobile phone 21 to which the SDP is connected and the PBAP correspondence flag are stored in the storage unit 5 in association with each other. There is no need to connect the phone information, and telephone information may be determined.

  As described above, according to the present embodiment, after the HFP is connected to the mobile phone 21 in the in-vehicle hands-free device 1, the SDP is connected to the mobile phone 21 that is connected to the HFP. As a result, the PBAP support flag of the mobile phone 21 is set as a PBAP support flag. After that, when the user performs an operation to instruct transfer of the phone book data, the mobile phone 21 refers to the PBAP support flag to and from the mobile phone 21. Since the connection is made by selecting either PBAP or OPP, which profile is compatible with the connection target mobile phone 21 after the user performs an operation to instruct transfer of the phone book data? The phone book data can be transferred from the mobile phone 21 to the in-vehicle hands-free device 1 without being conscious of whether or not, and the usability is high. Rukoto can.

  If the PBAP correspondence notification is notified from the mobile phone 21 within the specified time, the PBAP correspondence flag is set to “1”, while in other cases, the PBAP correspondence flag is set to “0”. If it comprises, the certainty of connecting PBAP can be improved. On the contrary, when the PBAP non-compliant notification is notified from the mobile phone 21 within the specified time, the PBAP compatible flag is set to “0”, while in other cases, the PBAP compatible flag is set to “1”. If it is configured to set, for example, a model that is compatible with PBAP but is not notified within a specified time or that cannot be notified can be set as a PABP connection target. Models that support PBAP can be widely relieved.

  Furthermore, when the PBAP-compatible flag is set to “1”, the mobile phone can be configured to connect the PBAP to the mobile phone 21 without performing an operation for instructing the transfer of the phone book data. Immediately after inquiring about the PBAP response status of the mobile phone 21, the phone book data can be automatically transferred from the mobile phone 21 to the in-vehicle hands-free device 1. The free device 1 can be automatically registered.

The present invention is not limited to the above-described embodiment, and can be modified or expanded as follows.
Instead of the in-vehicle hands-free device, the in-vehicle navigation device having a hands-free function may be used.
The SDP may be connected during the HFP connection procedure, or the SDP may be connected after the HFP connection procedure is completed.
