  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Here, as a plurality of mobile phones, n (n is a positive number of 2 or more) BT-compatible mobile phones (hereinafter referred to as mobile phones) having a Bluetooth (registered trademark) (hereinafter referred to as BT) communication function. ) Will be explained when it is brought into the passenger compartment. The in-vehicle hands-free device 1 is mounted on a vehicle, and includes a control unit 2 (control means, time measuring means, connection time detection means, connection frequency counting means in the present invention) and a BT interface section 3 (hands-free connection in the present invention). Means), a call voice processing unit 4, a storage unit 5 (storage unit in the present invention), a display control unit 6, and a touch operation input unit 7.

  The control unit 2 includes a CPU, a RAM, a ROM, an I / O bus, and the like, and controls overall operations such as communication operation and data management operation of the in-vehicle hands-free device 1. The control unit 2 has a calendar function for measuring the date and time. The BT interface unit 3 is a hands-free profile (HFP (Hands Free Profile)) (hands-free communication protocol according to the present invention), telephone directory data, and outgoing calls for performing hands-free calling standardized by the BT communication standard. Supports Phone Book Access Profile (PBAP) for transferring history data and incoming call history data, and connects hands-free profiles to each of multiple BT mobile phones simultaneously (So-called multi-profile connection) is possible.

  That is, if the mobile phones 21 to 2n each having the BT communication function are brought into the vehicle interior and the mobile phones 21 to 2n are present within the BT communication area formed by the BT interface unit 3, the BT interface unit 3 Connects the hands-free profile simultaneously with the mobile phones 21 to 2n existing in the BT communication area. These profiles mean communication protocols defined for each function.

  The call voice processing unit 4 is connected to a microphone 8 disposed in a portion of the vehicle interior where a user-generated voice such as the vicinity of a steering wheel is easy to collect, and the outside of the in-vehicle hands-free device 1. Is connected to the audio amplifier 9. When performing a hands-free call using any of the mobile phones 21 to 2n brought into the passenger compartment, the call voice processing unit 4 inputs the voice uttered by the user from the microphone 8 as the transmission voice. The input transmission voice is processed and output to the BT interface unit 3. When the reception voice is input from the BT interface unit 3, the input reception voice is output to the audio amplifier 9. When receiving the received voice from the call voice processing unit 4, the audio amplifier 9 amplifies the received received voice and outputs it from the speaker 10 and the speaker 11.

  The speaker 10 and the speaker 11 are arranged symmetrically about the full length direction of the vehicle on which the in-vehicle hands-free device 1 is mounted. The speaker 10 is arranged, for example, on the driver's seat door, and the speaker 11 is, for example, the passenger's seat door Is arranged. The audio amplifier 9 is also connected to the tuner deck 12. When the tuner deck 12 inputs, for example, music sound reproduced from a recording medium for music or a radio program received from a radio broadcasting station from the tuner deck 12, the audio amplifier 9 is connected to the tuner deck 12. The input music sound and radio program are amplified and output from the speakers 10 and 11.

  The storage unit 5 is configured to be able to store various types of data, and includes phone book data indicating correspondence between a telephone number and a registered name, transmission from the in-vehicle hands-free device 1, or hands to the in-vehicle hands-free device 1. Call history data indicating correspondence between call time and call phone number related to calls from the mobile phones 21 to 2n connected to the free profile, and mobile phones connected to the in-vehicle hands-free device 1 The incoming call history data indicating the correspondence between the incoming time and the incoming telephone number related to incoming calls at the telephones 21 to 2n can be stored, and as shown in FIG. 2, the telephone information (for example, telephones) of the mobile telephones 21 to 2n is stored. The telephone information registration data indicating the correspondence between the number, etc.), the owner, and the use (purpose of use) can be stored.

  In this case, the user registers the correspondence between the phone information, the owner, and the application when the mobile phones 21 to 2n that permit the hands-free connection to the in-vehicle hands-free device 1 are registered in advance. 2, the telephone information, the owner, and the use of the mobile phone are associated with each other by performing an operation of registering the telephone information, the owner, and the use, and are stored in the storage unit 5 as telephone information registration data. These owners and uses correspond to the attributes of the mobile phones 21 to 2n.

  The display device 13 includes a display device 14 that displays a display screen (notification means and display means in the present invention) and a touch operation input device 15 that forms a touch switch on the display screen. When the display command signal is input from the control unit 2, the display control unit 6 controls the display operation of the display device 14 in the display device 13 based on the input display command signal. 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.

  The above-described mobile phones 21 to 2n receive an incoming signal from the mobile phone network 31 (the communication network in the present invention) in a state where the hands-free profile is not connected to the in-vehicle hands-free device 1 (single state). Then, an incoming message indicating that the incoming call has been displayed is displayed on a display device (not shown), or a pre-registered ring tone is output from a speaker (not shown) to notify the user of the incoming call. A notification operation is performed.

  In this case, if the mobile telephones 21 to 2n have received the destination telephone number from the mobile telephone network 31, the mobile telephone network 31 displays the destination telephone number received from the mobile telephone network 31 on the display device or displays the phone book data. Search and display the registered name corresponding to the destination telephone number on the display device, or output the ringtone registered corresponding to the destination telephone number from the speaker to make a call. Information about the destination is also notified to the user. When the user recognizes an incoming call and operates an incoming call response key for responding to the incoming call, the mobile telephones 21 to 2n transmit an incoming call response signal to the mobile phone network 31. When the user recognizes an incoming call and operates an incoming call rejection key for rejecting the incoming call, an incoming call rejection signal is transmitted to the mobile phone network 31.

  On the other hand, when the mobile phones 21 to 2n receive an incoming signal from the mobile phone network 31 in a state where the hands-free profile is connected to the in-vehicle hands-free device 1, the incoming call from the own device as described above. The incoming call notification signal is transmitted to the in-vehicle hands-free device 1 without performing the notification operation. In this case, the cellular phones 21 to 2n transmit identification information (for example, a telephone number registered in the own device) identifying the own device to the in-vehicle hands-free device 1 and the destination telephone number from the cellular phone network 31. If received, the destination telephone number received from the cellular phone network 31 is also transmitted to the in-vehicle hands-free device 1. In addition, if the mobile phone 21 to 2n is a mobile phone that supports the in-band ring tone (a mobile phone that can transfer a ring tone registered in the mobile phone), the mobile phone is registered in the mobile phone. The incoming ring tone is also transmitted to the in-vehicle hands-free device 1.

  That is, each of the mobile phones 21 to 2n is a mobile phone that supports the in-band ring tone, and if it does not receive a destination telephone number from the mobile phone network 31, an unspecified number of phones The ring tone registered in advance corresponding to the number is transmitted to the in-vehicle hands-free device 1 and the destination telephone number is received from the mobile phone network 31, and the incoming call is received in advance corresponding to the received destination telephone number. If the sound is registered, the ringtone registered in advance is transmitted to the in-vehicle handsfree device 1.

  Next, the operation of the above configuration will be described with reference to FIGS. Here, as shown in FIG. 3, five mobile phones 21 to 25 are brought into the passenger compartment, and the mobile phone 21 is a mobile phone in which “phone information A” is registered. The mobile phone 22 is a mobile phone in which “telephone information B” is registered, the mobile phone 23 is a mobile phone in which “telephone information C” is registered, and the mobile phone 24 is registered in “phone information D”. It is assumed that the mobile phone 25 is a mobile phone in which “telephone information E” is registered, and each has a hands-free profile connected to the in-vehicle hands-free device 1 at the same time. Will be described. Further, for example, the explanation will be made on the assumption that “Higashida OO” recognizes “Higashida OO” as a driver by performing an operation of registering himself / herself as a driver in the in-vehicle handsfree device 1. To do.

  In the in-vehicle hands-free device 1, the control unit 2 receives an incoming notification signal from any one of the mobile phones 21 to 25 by the BT interface unit 3, and when an incoming processing start trigger is generated, the incoming processing shown in FIG. Start. When the incoming call process is started, the control unit 2 determines whether or not there is a mobile phone already receiving a call at that time (step S1).

  Here, it is assumed that one of the mobile phones 21 to 25 has received an incoming call when none of the mobile phones 21 to 25 has received the call. When the control unit 2 determines that there is no mobile phone that has already received a call when any of the mobile phones 21 to 25 arrives ("NO" in step S1), the owner of the mobile phone that has received the call When it is determined whether or not the driver is a driver (step S2), and it is determined that the owner of the incoming mobile phone is a driver ("YES" in step S2), the use of the incoming mobile phone is used for work. (Step S3), and based on those determination results, the incoming call information related to the incoming call is displayed (steps S4 to S6). The incoming call information here is a message indicating that the incoming call is being received, a destination telephone number notified from the incoming mobile phone, and phonebook data corresponding to the notified destination telephone number. The registered name, the owner registered for the incoming mobile phone, and information about the usage.

  In other words, if the mobile phone 21 receives an incoming call, the control unit 2 has a mobile phone in which “Higashida ○○” is registered as the owner and “work” is registered as the use as shown in FIG. Incoming information 41 indicating that 21 has arrived is displayed in the display area with a green background color on the upper right side (step S4). In addition, if the mobile phone 22 receives an incoming call, the control unit 2 has a mobile phone in which “Higashida ○○” is registered as the owner and “Private use” is registered as the use as shown in FIG. Incoming information 42 indicating that 22 has arrived is displayed in the display area with a green background color on the lower right side (step S5). Further, if the mobile phone 23 receives an incoming call, the control unit 2 has a mobile phone in which “Nishimura OO” is registered as the owner and “work” is registered as the use as shown in FIG. Incoming information 43 indicating that 23 has received is displayed in the display area with a yellow background color on the upper left side (step S6).

  On the other hand, it is assumed that when any one of the mobile phones 21 to 25 is already receiving a call, the other is receiving a call. When the control unit 2 determines that there is a mobile phone that has already received a call when any one of the mobile phones 21 to 25 is received ("YES" in step S1), the owner of the mobile phone that has received the call If it is determined whether or not the driver is a driver (step S7), and it is determined that the owner of the incoming mobile phone is a driver ("YES" in step S7), the use of the incoming mobile phone is used for work. Is determined (step S8), and it is determined that the use of the incoming mobile phone is for work (“YES” in step S8), the owner of the incoming mobile phone is the driver. It is determined whether or not there is (step S9), and the incoming call information related to the incoming call is displayed based on those determination results (steps S10 to S12).

  That is, if the mobile phone 21 receives a call while the mobile phone 22 is already receiving a call, the control unit 2 registers “Higashida ○○” as the owner as shown in FIG. From the state where the incoming call information 44 indicating that the mobile phone 22 registered for “private use” has arrived is displayed in the display area with a green background color on the lower right side, the owner “Higashida ○○ ”Is registered and the incoming call information 45 indicating that the mobile phone 21 registered as“ use ”has been received is interrupted and displayed with a green background color on the upper right side in the display area. The incoming call information 22 and the incoming call information of the mobile phone 21 are simultaneously displayed (step S10).

  Further, if the mobile phone 21 has received a call while the mobile phone 23 is already receiving a call, the control unit 2 registers “Nishimura OO” as the owner and uses it as shown in FIG. From the state where the incoming information 46 indicating that the mobile phone 23 registered for “work” has arrived is displayed in the display area with a yellow background color on the upper left, “Higashida ○○” as the owner. Is displayed and the incoming call information 47 indicating that the mobile phone 21 registered as “use” has been received is interrupted and displayed on the upper right side with a green background color. And the incoming information of the mobile phone 21 are displayed simultaneously (step S11).

  Further, when the control unit 2 determines that the use of the received mobile phone is not for work (“NO” in step S8), the control unit 2 rejects the display of the incoming call information indicating that the incoming call is received (step S12). Continue to display the incoming call screen for incoming calls. In other words, the control unit 2 uses the mobile phone that has received the first call for work (first type in the present invention), for example, and uses the mobile phone that has received the next call for private use (first in the present invention). If it is determined that the received information is a private type mobile phone, the display of the incoming call information indicating that the private mobile phone has received the call is rejected.

  If control unit 2 determines that the owner of the incoming mobile phone is not the driver (“NO” in step S7), the owner of the incoming mobile phone is the owner of the mobile phone that has received the call first. (Step S13), and based on those determination results, incoming call information related to the incoming call is displayed (steps S14 and S15).

That is, if the mobile phone 24 has already received an incoming call and the mobile phone 24 has received an incoming call, the control unit 2 registers “Nishimura OO” as the owner and uses it as shown in FIG. From the state where the incoming information 48 indicating that the mobile phone 23 registered for “work” has arrived is displayed in the display area with a yellow background color on the upper left, as the owner, “Nishimura XX” Is received and the incoming call information 49 indicating that the mobile phone 24 registered as “Private” has been received is interrupted and displayed with a yellow background color on the lower left side in the display area. And the incoming information of the mobile phone 24 are simultaneously displayed (step S14).

  Further, if the mobile phone 25 has received an incoming call while the mobile phone 24 is already receiving a call, the control unit 2 registers “Nishimura OO” as the owner and uses it as shown in FIG. From the state where the incoming call information 50 indicating that the mobile phone 24 for which “for private use” is registered is received is displayed in the display area with a yellow background color on the upper left side, the owner “Nanno XX” Is received and the incoming call information 51 indicating that the mobile phone 25 registered as “Private” has been received is displayed in the display area with a blue background color on the lower left side, and the mobile phone 24 is displayed. And the incoming information of the mobile phone 25 are simultaneously displayed (step S15).

  In the above, the case where the incoming call information is displayed by distinguishing the background color and the display position based on the owner of the incoming mobile phone has been described. However, the character color, lighting pattern, etc. The incoming call information may be displayed by distinguishing the blinking pattern. The incoming call information may be displayed by distinguishing the background color, the character color, the display position, the lighting pattern, and the flashing pattern based on the use of the mobile phone that has received the call. In addition, when displaying a plurality of incoming call information, the incoming call information of the mobile phone that has been received first is displayed by lighting, and the incoming call information of the mobile phone that has been received next is displayed by blinking. You may make it recognize. Furthermore, the owner or usage may be highlighted by displaying the background color of the owner or usage portion of the incoming call information separately from the background color of other portions.

  In the above, when the incoming information of the mobile phone that the owner is the owner is displayed, the incoming information is displayed on the side closer to the driver in the display area of the display device 14, that is, in-vehicle hands-free. If the vehicle on which the device 1 is mounted is a vehicle having a steering wheel on the right side (a so-called right-hand drive vehicle), the incoming information on the mobile phone owned by the driver is displayed in the display area of the display device 14 as in this embodiment. A mode in which the vehicle is displayed on the right side that is closer to the driver's seat when viewed from the front is preferable. On the other hand, if the vehicle on which the in-vehicle hands-free device 1 is mounted is a vehicle having a handle on the left side (a so-called left-hand drive vehicle) It is desirable that the incoming information related to the cellular phone owned by the person is displayed on the left side that is closer to the driver's seat when viewed from the front in the display area of the display device 14.

  By the way, the above describes the case where any one of the mobile phones 21 to 25 is already receiving a call while the other is receiving a call. However, when any one of the mobile phones 21 to 25 is already calling. A case where one of the other calls arrives will be described with reference to FIGS. In this case, when the control unit 2 determines that there is no mobile phone already in communication when any of the mobile phones 21 to 25 is received (“NO” in step S21), the above-described steps S2 to S6 are performed. Steps S22 to S26 are performed. When it is determined that there is a mobile phone already in a call when any of the mobile phones 21 to 25 is received ("YES" in Step S21), the above steps are performed. Steps S27 to S35 corresponding to S7 to S15 are performed. In this case, as shown in FIGS. 13 to 16, the control unit 2 displays the call information 61, 63, 65, 67 indicating that any one of the mobile phones is busy, The incoming call information 62, 64, 66, 68 indicating that any of the mobile telephones has been received is interrupted and displayed, and the call information of the mobile telephone and the incoming information of the mobile telephone are displayed simultaneously.

  In addition, when the usage is stored as the attributes of the mobile phones 21 to 2n as shown in FIG. 2, the usage that is the attribute of the mobile phones 21 to 2n is collated with the date and time when the incoming call is received. The incoming information of two mobile phones in the above may be displayed on the mobile phone with priority set. Hereinafter, the case where the control unit 2 sets and displays the priority order will be described with reference to FIGS. 17 and 18.

  When the incoming call process is started, the control unit 2 determines whether the number of mobile phones that are receiving calls is one or two (steps S41 and S42). Here, when the control unit 2 determines that the number of mobile phones that are receiving a call is one (“YES” in step S41), the display unit 14 displays a display screen when one call is received ( Step S43). In this case, if the call destination telephone number is received from the incoming mobile phone, the control unit 2 displays the received call destination telephone number, and stores the registered name corresponding to the call destination telephone number in the phone book data. If it is stored, the registered name is also displayed.

  Then, the control unit 2 determines whether or not a user operation has been performed on the display screen at the time of arrival of one unit (step S44), and determines that the user operation has been performed (in step S44, “ YES ”), processing according to the user's operation is performed (step S45). That is, the control unit 2 receives an incoming call response switch for responding to an incoming call, an incoming call rejection switch for rejecting the incoming call, an up switch for increasing the volume of the ringtone, and lowers the volume of the ringtone When the incoming call response switch is operated, an incoming response signal is transmitted from the BT interface unit 3 to the mobile phone, while the incoming call reject switch is operated. When the incoming call rejection signal is transmitted from the BT interface unit 3 to the mobile phone and the up switch is operated, the audio amplifier 9 is controlled to increase the volume of the incoming call sound, and when the down switch is operated, the audio is transmitted. The amplifier 9 is controlled to lower the volume of the ringtone.

  If control unit 2 determines that the number of mobile phones that are receiving calls is two ("YES" in step S42), the use of the two mobile phones that are receiving calls is the same. It is determined whether or not priorities can be set for the two mobile phones that are receiving calls (step S46). In other words, when the usages of two mobile phones that are receiving a call are the same, the control unit 2 determines that the priority cannot be set for the two mobile phones that are receiving a call (step S2). In S46, “NO”), the display screen at the time of receiving two phones is displayed on the display device 14 without setting the priority order of the two mobile phones that are receiving calls (step S47).

  FIG. 18A shows the same use of two mobile phones that are receiving a call. One of the two mobile phones that are receiving a call is designated as “090 *******” as a destination telephone number. "Is stored as phonebook data as a registered name corresponding to the destination telephone number received from the mobile phone, and" 090 ****** "as the destination telephone number. "01" and "Tokukawa OO" as a registered name are displayed as incoming information 71 on the left half of the display area of the display device 14, and at the same time, "090 ******" "02" is stored as phone book data as a registered name corresponding to the destination telephone number received from the mobile phone, and "090 ****" as the destination telephone number. * 02 "and" weaving "as a registered name ○○ "shows an example that is displayed on the right half of the display area of the display device 14 as the incoming information 72.

  On the other hand, if the usages of the two mobile phones that are receiving a call are different, the control unit 2 determines that the priority order can be set for the two mobile phones that are receiving the call (step S2). If “YES” in S46), it is determined whether the date and time at that time is, for example, a weekday or a holiday. When the usage of the two mobile phones that are receiving calls is different for work use and private use, the control unit 2 sets the priority of the work mobile phone high when it is a weekday, for example, When it is a holiday, the priority of the private mobile phone is set high. Then, the control unit 2 sets the priority order of the two mobile phones that are receiving the incoming call, and causes the display device 14 to display a display screen when the two incoming calls are received (step S48).

  In FIG. 18B, the usages of the two mobile phones that are receiving a call are different, and “090 ****** 01” is set as the destination telephone number from one of the two mobile phones that are receiving a call. “Tokukawa XX” is stored as phonebook data as a registered name corresponding to the destination telephone number received and received from the mobile phone, and “090 ********” as the destination telephone number. And “Tokukawa XX” as the registered name is displayed on the left half of the display device 14 as the incoming information 71, and at the same time, “090 ********” is received as the destination telephone number from the other side. , “Toyotomi XX” is stored as phonebook data as a registered name corresponding to the destination telephone number received from the mobile phone, and “090 ****** 03” is registered as the destination telephone number. Received "Toyoomi XX" as a name It shows an example that is displayed on the right half of the display area of the display device 14 as a broadcast 73.

  In this case, the control unit 2 uses the mobile phone received from the mobile phone to which “090 ****** 01” is assigned as the telephone number for work, and uses “090 ***” as the telephone number. If the use of the mobile phone receiving from the mobile phone to which “******” is given is for private use, and it is a holiday, set the priority of the mobile phone for use for private use high, and Information indicating that the priority is high in the incoming information of the mobile phone for use (character information “priority” in the incoming information 73 in FIG. 18B) is displayed.

  The control unit 2 also displays the display screen when two units are received on the display screen when two units are received in the same manner as when displaying the display screen when one unit is received. It is determined whether or not a user operation has been performed (step S44). When it is determined that a user operation has been performed ("YES" in step S44), processing corresponding to the user operation is performed (step S45). ). When the incoming call of all the mobile phones is finished, the control unit 2 performs a process according to the state of the mobile phone that has finished the incoming call (step S49), and returns.

  In addition to displaying the text information “priority”, the method of notifying the user indicating that the priority is high may display the background color and the character color separately, or the higher priority The lighting pattern or the blinking pattern may be distinguished and displayed, for example, the lower priority order is turned on at the same time as flashing, for example, the higher priority order is in the display area of the display device 14 and closer to the driver For example, the display position may be distinguished and displayed.

  In addition to using a pre-registered use of a mobile phone, the method of setting the priority order is not limited to the BT for each mobile phone every time the BT interface unit 3 connects a hands-free profile with the mobile phone. The time when the hands-free profile is connected to the interface unit 3 is updated and stored in the storage unit 5, and the time when the hands-free profile is connected to the BT interface unit 3 is the priority of the past (early) mobile phone. The order may be set higher, or each time the BT interface unit 3 connects the hands-free profile to the mobile phone, the number of times the hands-free profile is connected to the BT interface unit 3 for each mobile phone is stored. The update is stored in the unit 5, and a hands-free profile is connected to the BT interface unit 3. It may be set higher the priority of a large number mobile phone.

  As described above, according to the present embodiment, in the in-vehicle hands-free device 1, it is determined that each of the plurality of mobile phones 21 to 2n connected to the hands-free profile is receiving a call at the same time. When it is determined that is in a call and the other is in an incoming call, the incoming call information or the call information notification mode is based on the attributes (for example, owner, usage, etc.) of the mobile phone during the incoming call or the incoming call. Since it is configured to distinguish and notify (for example, background color, etc.), the user can appropriately recognize the state of each of the plurality of mobile phones 21 to 2n, and the user's convenience can be improved.
