  Since the audio unit 22 has the same configuration as a general car audio device, detailed description thereof will be omitted, but under the control of the control unit 20, a CD (Compact Disc) playback process and a radio reception process And corresponding sound is emitted from a speaker disposed in the vehicle.

  An input interface (input I / F) 23 is used for audio operations such as an operator for CD playback as well as an operator for hands-free calling such as a numeric keypad for inputting a telephone number and an operator for instructing start of authentication. It is provided with the operation element. That is, the control unit 20 inputs various instructions from the user via the input I / F 23, and appropriately performs hands-free call control and control of the audio unit 22 according to the instructions.

  The communication interface (communication I / F) 24 is a general-purpose communication interface such as RS (Recommended Standard) -232C, USB (Universal Serial Bus) or the like, or a communication interface of an original standard. The unit 25 and the biological information detection unit 26 are connected.

  The voice input unit 25 is used to input a transmission voice during a hands-free call, and includes a microphone, an amplifier, and the like. Thus, since the voice input unit 25 is connected via the communication I / F 24, it is possible to arrange the voice input unit 25 at a position where it is easy to input the voice of the user (driver) such as on the handle or the dashboard. ing. However, the voice input unit 25 may be built in the hands-free call device 10.

  The biological information detection unit (detection means) 26 detects a user's biological information, and in this embodiment, a fingerprint detection unit that detects a fingerprint is applied. The biological information detection unit 26 starts reading the fingerprint under the control of the control unit 20 and outputs the read fingerprint data. The biometric information detection unit 26 is provided with a fingerprint reading unit for reading at least a fingerprint on the handle of the vehicle so that the driver's fingerprint can be read basically at any time while the driver is driving.

  The wireless communication unit 30 performs short-range wireless communication in accordance with the Bluetooth (registered trademark) standard under the control of the control unit 20, and forms a communication area around and is located in this communication area. Wireless communication with the mobile phone 100 is performed. The communication method is not limited to Bluetooth, but may be another wireless communication method such as a wireless LAN, and the wireless communication unit 30 may be a general-purpose wireless communication unit that can be attached to and detached from the hands-free call device 10.

  Specifically, the wireless communication unit 30 performs predetermined modulation processing on transmission data such as a transmission voice input via the communication control circuit 31 that controls the entire wireless communication unit 30 and the voice input unit 25. A modulation circuit 32 for performing transmission, an output circuit 34 for transmitting a radio signal from the antenna 33 based on an output signal of the modulation circuit 32, an amplification circuit 35 for amplifying a signal such as a transmitted voice received via the antenna 33, The demodulating circuit 36 is configured to perform predetermined demodulation processing on the received signal.

  Next, a mobile phone (telephone terminal) 100 that can be used in the handsfree call device 10 will be briefly described. The mobile phone 100 is used for call communication with other mobile phones and fixed phones via a mobile communication network (not shown), and is a general mobile phone such as a speakerphone, a microphone, or a communication unit for call communication. In addition to the configuration provided by the wireless communication unit 30, a wireless communication unit (not shown) having the same configuration as the wireless communication unit 30 is provided. In addition, the mobile phone 100 has its own phone number stored in the built-in memory, as in a general mobile phone, and the wireless communication unit transmits the phone number stored in the built-in memory, It is possible to wirelessly perform voice communication such as transmission of received voice and reception of transmitted voice. The display unit 27 displays various kinds of information, and includes, for example, a liquid crystal display panel, a liquid crystal driving circuit, and the like.

  By the way, the hands-free communication device 10 is wirelessly connected to one mobile phone 100 when a vehicle ignition key is turned on (at least an accessory power supply is turned on), or when an activation instruction is inputted via the input I / F 23. A hands-free call system capable of hands-free calling is established via the mobile phone 100 by connecting. The operation when constructing this hands-free call system will be described below.

  FIG. 2 is a flowchart showing an operation for constructing a hands-free call system.

  First, the control part 20 performs the driver determination process which determines whether the person seated in a driver seat is a use permission person (step S1). Specifically, the control unit 20 drives the biological information detection unit 26, reads the fingerprint of the person holding the handle by the biological information detection unit 26, and inputs the fingerprint data via the communication I / F 24. Subsequently, the control unit 20 collates the input fingerprint data with the biological information D1 (fingerprint data) stored in the storage unit 21, calculates the degree of coincidence by calculation, and the degree of coincidence is a predetermined threshold level. It is determined whether it is above.

  When the degree of coincidence is equal to or higher than the threshold level, that is, when the input fingerprint data is compared with the biometric information D1 (fingerprint data) stored in the storage unit 21, it is determined that the user is the authorized user (step S2). : YES), the control unit 20 searches the mobile phone 100 of the authorized person (step S3).

  Specifically, the control unit 20 obtains telephone number information from the mobile phone 100 by performing wireless communication with the mobile phone 100 located in the communication area by the wireless communication unit 30, and the phone number is stored in the memory. It is determined whether or not it matches the identification information D2 (telephone number) stored in the unit 21. Here, when there are a plurality of mobile phones 100 in the communication area, the control unit 20 acquires a telephone number from each mobile phone 100 by wireless communication, and determines whether or not it matches the identification information D2. .

  When the control unit 20 obtains a telephone number that matches the identification information D2 and determines that the mobile phone 100 of the authorized user has been found (step S4: YES), the wireless communication unit 30 causes the mobile phone 100 (hereinafter referred to as the mobile phone 100). And a mobile phone 100a), a communication synchronization is established and wireless connection is established to construct a hands-free call system (step S4).

  When the hands-free call system is constructed as described above, the control unit 20 enters a state of waiting for an incoming / outgoing call of the mobile phone 100a connected wirelessly, and controls a hands-free call via the mobile phone 100a. Specifically, for example, when a call instruction or a telephone number is input via the input I / F 23, the control unit 20 transmits a call command and a telephone number via the wireless communication unit 30 and performs a call process to the mobile phone 100a. After that, by performing voice communication with the mobile phone 100a, the received voice received by the mobile phone 100a is emitted from the speaker, and the transmitted voice input via the voice input unit 25 is sent to the mobile phone 100a. Make a voice input.

  Further, the control unit 20 detects an incoming call by receiving an incoming call trigger signal (including an incoming call sound signal) wirelessly transmitted from the mobile phone 100a via the wireless communication unit 30, and in this case, the incoming call sound is received. When sound is emitted from the speaker and a call instruction is input via the input I / F 23, a corresponding control command is transmitted to control the mobile phone 100a to a call state and perform voice communication with the mobile phone 100a.

  As a result, the case where only the mobile phone 100a is used for a hands-free call and a call is made via the other mobile phone 100 or the incoming call of the other mobile phone 100 is avoided.

  In addition, when the hands-free call system is constructed, the control unit 20 determines whether or not the driver has been changed by performing the same driver determination process as in step S1 at predetermined time intervals (step S6). Then, when it is determined that the driver has changed (step S6: YES), the control unit 20 determines whether or not the ignition key of the vehicle is turned off (supply of accessory power is stopped) for a predetermined time ( In step S7), when turned off, the process ends (step S7: YES). If the ignition key remains on, the process proceeds to step S1, and the driver determination process is performed again. As a result, when the driver changes, the hands-free call device 10 is configured such that the hands-free call system is canceled and a hands-free call by a person whose use is not permitted can be regulated.

  Here, in the determination in step S2, if the driver is not an authorized user (step S2: NO), the control unit 20 displays a message such as “Do you want to register new” on the display unit 27, or The voice of the message is emitted from the speaker, and the driver is prompted to select whether or not to newly register (step S10). Then, when it is selected that the new registration is not performed via the input I / F 23 (step S10: NO), the control unit 20 terminates this process, while when it is selected that the new registration is performed (step S10). : YES), a process of storing the biometric information D1 of the newly registered person and the identification information D2 of the telephone number in the storage unit 21 is started.

  Specifically, the control unit 20 searches for all mobile phones 100 located in the communication area by the wireless communication unit 30 and acquires the telephone numbers of these mobile phones 100 by wireless communication (step S11). The telephone number is displayed on the display unit 27, and the user is prompted to select the telephone number of the mobile phone 100 in order to prompt new registration (step S12). When the telephone number is selected via the input I / F 23 (step S12: registration), the control unit 20 stores the fingerprint data acquired in the process of step S1 in the storage unit 21 as the biological information D1, After the selected telephone number is stored in the storage unit 21 as the identification information D2, the process proceeds to step S5.

  On the other hand, if the telephone number of the newly registered user's mobile phone 100 is not displayed in step S12 and that fact is input via the input I / F 23 (step S12: registration is impossible), the control unit 20 enters the communication area. All the mobile telephones 100 in the area are searched again (step S11), and the telephone numbers of these mobile telephones 100 are displayed again to prompt selection of the telephone numbers (step S12). Thus, a new registrant can easily register the telephone number of his / her mobile phone 100 without having to input the telephone number one by one.

  In this case, in the process of step S5, the control unit 20 wirelessly connects only to the mobile phone 100 corresponding to the newly registered identification information D2, whereby the new registrant immediately passes through his / her mobile phone 100. A hands-free call can be made.

  Further, at the time of new registration in steps S10 to S12, the control unit 20 updates the biometric information D1 and the identification information D2 stored in advance in the storage unit 21 to the biometric information D1 and the identification information D2 to be newly registered. (Rewriting) may be performed, or additional registration may be performed.

  In the case of additional registration, the biometric information D1 and the identification information D2 are stored in association with each authorized user, and the control unit 20 stores the input fingerprint data and the storage unit 21 in steps S1 and S2. Each stored biometric information D1 is collated, and in steps S3 and S4, the mobile phone 100 having a telephone number that matches the identification information D2 associated with the collated biometric information D1 is searched. It becomes possible to have a plurality of authorized persons for hands-free calling.

  On the other hand, if the telephone number that matches the identification information D2 cannot be acquired in the determination in step S4 (step S4: NO), the control unit 20 displays the telephone numbers of all the mobile phones 100 searched in step S3. The user 27 (permitted user) is prompted to select a telephone number to be displayed on the unit 27 and to encourage new registration (step S8). When a telephone number is selected via the input I / F 23, the control unit 20 updates the identification information D2 stored in the storage unit 21 to the selected telephone number (step S9), and then proceeds to step S5. Then, the wireless connection is established with only the mobile phone 100 corresponding to the newly registered identification information 2.

  Thereby, even when the authorized person changes his / her mobile phone 100, the user can easily register a new phone number of the mobile phone 100 and can immediately make a hands-free call. In addition, when the telephone number to be registered is not displayed in step S8 and that fact is input via the input I / F 23, or when no operation is performed for a predetermined period (step S8: registration is not possible), The control unit 20 re-searches all the mobile phones 100 located in the communication area (step S3), displays the phone numbers of these mobile phones 100 again, and prompts the user to select a phone number (step S8). Thus, the authorized person can easily register a new phone number of the mobile phone 100 without inputting the phone number one by one.

  As described above, the hands-free call device 10 collates the fingerprint data acquired by the biometric information detection unit 26 with the biometric information D1 stored in advance, and can collate the data, and the wireless communication unit 30 performs the collation beforehand. When a mobile phone 100 having a telephone number that matches the stored identification information D2 is searched, a hands-free call is permitted through the mobile phone 100, so that only the authorized user can use his / her mobile phone 100a. It can be used to make a hands-free call, and it is possible to restrict a person other than the authorized user from making a hands-free call.

  In addition, when the verification cannot be performed, the hands-free call device 10 prompts the user to select whether or not to newly register, and if new registration is to be performed, the telephone number of the mobile phone 100 acquired by wireless communication is prompted. The user is prompted to select a telephone number, and the fingerprint data acquired by the biological information detection unit 26 and the selected telephone number are registered in the storage unit 21 as the biological information D1 and the identification information D2, respectively. This new registrant can make a hands-free call using his / her mobile phone 100.

  In addition, when additional registration is performed in this way, biometric information D1 and identification information D2 are stored in association with each authorized person, so that a predetermined number of persons can each have their own mobile phone 100. It becomes possible to make a hands-free call using.

  Further, when the mobile phone 100 having a telephone number that matches the pre-stored identification information D2 is not found, the hands-free call device 10 makes a call from the telephone numbers of the mobile phone 100 acquired by wireless communication. The user is prompted to select a number, and the selected telephone number is registered in the storage unit 21 as identification information D2. Therefore, even if the authorized person changes his / her mobile phone 100, the mobile phone 100 can be registered easily. A hands-free call can be performed.

  The embodiment described above shows one aspect of the present invention, and does not limit the present invention, and can be arbitrarily changed within the scope of the present invention. Further, the configuration shown in the embodiment is not limited to the configuration, and can be appropriately changed without departing from the gist of the present invention. For example, in the above-described embodiment, the case where the mobile phone 100 having the telephone number matching the identification information D2 is searched after the driver determination processing has been described. However, the driver determination processing is performed after this search. The order may be arbitrary.

  Further, in the above-described embodiment, the biometric information D1 is fingerprint data. However, various biometric information such as a voice print of a licensee or voice data of uttered voice or body weight can be widely applied. A plurality of types of biological information may be used. In this case, the voice input unit 25 can also be used as the biological information detection unit 26, and a weight sensor may be arranged under the seat and the weight sensor may be used as the biological information detection unit 26.

  In the above-described embodiment, the identification information D2 is a telephone number. However, the identification information D2 may be any information that can identify the mobile phone 100. It may be assigned address information (MAC address or Bluetooth Device Address).

  Furthermore, in the above-described embodiment, the case has been described in which the mobile phone 100 is used as a hands-free call. However, it is possible to widely apply phone terminals such as PHS and IP phones having a wireless communication function. . Moreover, although the case where the present invention is applied to the hands-free call device 10 used in the vehicle has been described, it can be widely applied to hands-free call devices used outside the vehicle.

  Furthermore, in the above-described embodiment, the case where the control program is stored in advance in the storage unit 21 has been described. However, the control program can be read by a computer such as a magnetic recording medium, an optical recording medium, or a semiconductor recording medium. It may be stored in a recording medium, and the computer may read this control program from the recording medium and execute it.
