  As shown in FIG. 11A, a conventional in-vehicle communication system has an in-vehicle device 10 mounted on a two-wheeled vehicle, a mobile terminal (for example, a smartphone) 20 connected to the in-vehicle device 10, and a hands-free call function. And the headsets 30 and 40 provided. The headset 30 is built in a driver's helmet, and the headset 40 is built in a passenger's helmet. The in-vehicle device 10 includes USB communication 50 that performs bidirectional data communication with the mobile terminal 20, and three wireless modules 1, 2, and 3 that perform wireless communication with the mobile terminal 20 and the headsets 30 and 40. The wireless modules 1, 2, and 3 are short-range wireless communication such as Bluetooth (registered trademark), for example, and the wireless modules 1, 2, and 3 are profiles (for example, AVP) and hands for communicating audio signals. A profile (for example, HFP) for making a free call is included. Similarly, the portable terminal 20 and the headsets 30 and 40 include a wireless module having a profile such as AVP or HFP. The portable terminal 20 is connected to the wireless module 1, and the headsets 30 and 40 are respectively connected to the wireless modules 2, 3 and 40. Connected to.

  When a hands-free call is performed via the headsets 30 and 40, the hands-free call profile of the wireless modules 2 and 3 is selected. In the hands-free call, voice data input from the microphones of the headsets 30 and 40 is transmitted to the portable terminal 20 via the in-vehicle device 10, and the other party's voice data is transmitted from the portable terminal 20 via the in-vehicle device 10. , And 40 speakers.

  FIG. 11B illustrates an example of connecting a wireless module to a plurality of devices when one wireless module has a plurality of profiles. For example, when the wireless module X has a profile AVP for audio signals and a profile HFP for hands-free calling, the AVP of the wireless module X can be connected to the headset A and the HFP can be connected to the mobile terminal B.

  FIG. 12 is a flow for explaining an operation example of the in-vehicle communication system of FIG. The example here shows an operation when a hands-free call is made in response to an incoming call to the mobile terminal 20 when an audio signal reproduced on the mobile terminal 20 is output from the headsets 30 and 40. Yes.

  First, when the power of the in-vehicle device 10 is turned on, a connection request is made from the in-vehicle device 10 to the mobile terminal 20 and the headsets 30 and 40 by the wireless modules 1, 2, and 3, and the wireless module 1 The wireless module 2 is connected to the headset 30, and the wireless module 3 is connected to the headset 40. The in-vehicle device 10 is connected to the portable terminal 20 by USB communication 50.

  Next, when a request for music reproduction is made from the in-vehicle device 10 to the portable terminal 20 via the USB communication 50, the portable terminal 20 sends the audio signal reproduced in response to the request to the portable terminal 20 via the USB communication 50. Transmit to device 10. When receiving the audio signal, the in-vehicle device 10 selects a profile (AVP) for the audio signal of the wireless modules 2 and 3, and transmits the audio signal to the headsets 30 and 40 according to the profile. As a result, the driver and the passenger can listen to the audio signal reproduced on the mobile terminal 20.

  When the mobile terminal 20 receives an incoming call in such a connection state, the mobile terminal 20 interrupts the incoming information and the incoming sound into the audio signal, and the incoming information and the incoming sound are transmitted via the USB communication 50 to the in-vehicle device 10. Send to. The ring tone is transmitted from the in-vehicle device 10 to the headsets 30 and 40 according to the AVP, and the driver or passenger knows that there is an incoming call. The in-vehicle device 10 detects incoming information, and interrupts and displays a reception button for selecting a reception on the screen (for example, a navigation screen) of the in-vehicle device 10. When the reception button on the screen is selected, a reception selection signal is transmitted from the in-vehicle device 10 to the portable terminal 20 via the USB communication 50, and the portable terminal 20 stops audio reproduction in response to the reception selection signal, and The HFP of the wireless module 1 is selected. The in-vehicle device 10 selects the HFP of the wireless modules 2 and 3 in response to the reception selection signal. In this way, a hands-free call can be performed between the in-vehicle device 10, the portable terminal 20, and the headsets 30 and 40.

  However, the conventional in-vehicle communication system has the following problems. The in-vehicle device 10 requires three wireless modules, which increases the cost. In addition, since incoming information from the mobile terminal 20 is transmitted as audio information from the USB communication 50, the profile of the wireless module becomes AVP, and the reception button of the headset cannot be used. Therefore, an external reception switch (or reception button) is required in the in-vehicle device or the like.

  In addition, as shown in FIG. 11B, it is possible to obtain incoming information from the wireless module by limiting the profile of the wireless module to a profile for hands-free calling (HFP). In order to restrict, a user's intentional operation is required, and the operation is complicated and difficult to understand, and there is a case where a function for restricting a profile is not provided on the mobile terminal side. Furthermore, in the case of a conventional in-vehicle communication system, there arises a problem that a person who can make a call is fixed to one of a driver and a passenger. FIG. 11C shows a case where a person who can make a call is fixed. Since the HFP of the wireless module 1 is connected to the portable terminal 20 and the AVP is connected to the headset 30, the headset 30 is shown. Can hear a ring tone but cannot make a phone call, and the headset 40 is limited to a device capable of hands-free calling.

The driver or passenger can listen to music or make a hands-free call through the headsets 300 and 310.

  FIG. 2 is a block diagram illustrating a configuration example of the in-vehicle device 100. The in-vehicle device 100 includes an input unit 110 that receives input from a user, a position information calculation unit 120 that calculates a current position using a GPS signal, a navigation unit 130, a display unit 140, a voice output unit 150, a communication unit 160, The storage unit 170 and the control unit 180 are included.

  For example, the navigation unit 130 searches for a route from the current location calculated by the location information calculation unit 120 to the destination, and provides road guidance around the current location. The display unit 140 includes, for example, a liquid crystal display, an organic EL display, and the like, and displays an audio reproduction screen, a map display screen, an incoming call notification screen, and the like according to the operation state. The audio output unit 150 outputs audio such as an audio signal generated by the navigation unit 130, an audio signal transmitted from the mobile terminal 200, or an audio signal reproduced by the in-vehicle device itself.

  As illustrated in FIGS. 7 and 8, the communication unit 160 includes a plurality of wireless modules 162 and 164 such as Bluetooth (registered trademark) and a communication module 166 according to a communication standard different from the wireless modules 162 and 164. The wireless modules 162 and 164 have an audio signal profile (for example, AVP) that defines transmission / reception for an audio signal and a hands-free call profile (for example, HFP) that defines transmission / reception for performing a hands-free call. Each profile is appropriately selected according to the operating state. The wireless modules 162 and 164 can be connected to an external wireless module that supports the same communication profile, and can be connected to the mobile terminal 200 and the headsets 300 and 310 shown in FIG.

  The communication module 166 includes communication such as USB communication, for example, and enables bidirectional data communication with an external device (hereinafter referred to as USB communication for convenience). The USB communication 166 connects the in-vehicle device 100 and the portable terminal 200 as shown in FIG. 1. In one preferable example, when the in-vehicle device 100 and the portable terminal 200 are connected by the USB communication 166, the in-vehicle device 100 is connected. Shifts to a mode linked to the portable terminal 200. In the cooperation mode, the in-vehicle device 100 makes various requests to the mobile terminal 200, and the mobile terminal 200 outputs a result for the request to the in-vehicle device 100.

  The storage unit 170 stores map data required when the navigation unit 130 executes, or stores software necessary for the in-vehicle device 100 to operate.

  In a preferred embodiment, the control unit 180 includes a ROM, a RAM, a microcontroller, and the like, and the ROM / RAM can store various programs for controlling the operation of each unit of the in-vehicle device 100. In the present embodiment, the control unit 180 activates the cooperation program when the mobile terminal 200 is connected to the in-vehicle device 100 via the USB communication 166. When the cooperation program is activated, the in-vehicle device 100 can operate as an input / output unit of the mobile terminal 200. For example, the input unit 100 of the in-vehicle device 100 requests the mobile terminal 200 to play back media included in the mobile terminal 200, and the in-vehicle device 100 displays the playback data of the media received from the mobile terminal 200 with the display unit 140 and audio. Output from the output unit 150. In addition to such a cooperation program, the control unit 180 further executes a communication control program 400 that controls switching of the wireless modules 162 and 164 according to the operation state when the mobile terminal 200 is connected.

  FIG. 3 is a diagram illustrating a functional configuration of the communication control program according to the present embodiment. The communication control program 400 includes an incoming information detection unit 410, a communication profile selection unit 420, an incoming call detection unit 430, and a switching control unit 440.

  The incoming information detection unit 410 detects incoming information transmitted via the USB communication 166 when there is an incoming call in the mobile terminal 200. The incoming call information is information that can be used to determine that there has been an incoming call, and can include, for example, a caller number. When the mobile terminal 200 receives an incoming call, the incoming call information and the incoming call sound are transmitted to the in-vehicle device 100 via the USB communication 166.

  The communication profile selection unit 420 selects a communication profile of the wireless modules 162 and 164 according to the operation state of the in-vehicle communication system. For example, when a driver or a passenger listens to music played through the headsets 300 and 310, the communication profile selection unit 420 selects a profile (eg, AVP) for audio signals of the wireless modules 162 and 164. . When incoming information is detected by the incoming information detection unit 410 via the USB communication 166, the communication profile selection unit 420 selects a profile (for example, HFP) for the hands-free call of the wireless modules 162 and 164. To do. Thereby, the ring tone transmitted from the USB communication 166 is transmitted to the headsets 300 and 310 according to the HFP, so that the driver and the passenger can know that the mobile terminal 200 has received an incoming call. If there is an incoming call while the music played on the mobile terminal 200 is being listened to by the headsets 300 and 310, the music and the ring tone are transmitted to the headsets 300 and 310 according to the hands-free call profile. , Output from there.

  The incoming call detection unit 430 detects the presence or absence of an incoming call by a driver or a passenger in response to an incoming call to the mobile terminal 200. That is, when there is an incoming call, the wireless modules 162 and 164 transmit ringtones to the headsets 300 and 310 according to the hands-free call profile, but the reception button 340 of either the headset 300 or the headset 310 described later. When (see FIG. 6) is pressed, the reception detection unit 430 detects a reception selection signal when the reception button is pressed.

  The switching control unit 440 controls switching of the wireless modules 162 and 164 based on the detection result of the reception detection unit 430. Specifically, when the reception button 340 of the headset 300 is detected by the reception detection unit 430 via the wireless module 162, the switching control unit 440 moves the wireless module 164 not selected for reception from the headset 310. On the other hand, when the reception button 340 of the headset 310 is detected via the wireless module 164, the wireless module 162 not selected for reception is disconnected from the headset 300. Furthermore, the switching control unit 440 makes a connection request between the disconnected wireless module and the portable terminal 200 to the portable terminal 200 in order to connect the disconnected wireless modules 162 and 164 to the portable terminal 200. In response to the switching request, the portable terminal 200 connects to the disconnected wireless module. The communication profile selection unit 420 selects a profile for a hands-free call when connecting the disconnected wireless module to the mobile terminal 200. Thus, the wireless module connected to the headset that has not been selected for reception is connected to the portable terminal, and the portable terminal, the in-vehicle device, and one headset are connected by the hands-free call profile of the wireless modules 162 and 164.

  When the portable terminal 200 and the in-vehicle device 100 cooperate with each other, for example, when an audio signal reproduced by the portable terminal 200 is transmitted to the in-vehicle device 100 via the USB communication 166, a switching request from the switching control unit 440 is issued. When transmitted to the mobile terminal 200, the mobile terminal 200 connects to the disconnected wireless module and stops reproducing the audio signal. As a result, only the received sound is output from the headset selected for receiving.

  FIG. 4 is a block diagram illustrating a configuration of the mobile terminal. The mobile terminal 200 includes a call unit 210, a communication unit 220, an input unit 230 that receives input from a user, a display unit 240, an audio output unit 250, a storage unit 260, and a control unit 270. However, this is a typical configuration, and the mobile terminal 200 may include functions other than those described above.

  The call unit 210 enables a voice call with an external telephone via a wireless public line network or an Internet line network. The communication unit 220 establishes a connection by the wireless module and a connection by the USB communication 166 with the in-vehicle device 100. That is, the communication unit 220 includes a wireless module that can be connected to the wireless modules 162 and 164 of the in-vehicle device 100. The wireless module includes an audio signal profile (for example, AVP) and a hands-free call profile (HFP). Etc.

  The storage unit 250 can store media data (for example, music data and image data), programs, application software downloaded from an external server, and the like. In a preferred embodiment, the control unit 260 includes a ROM, a RAM, a microcontroller, and the like, and the ROM or the RAM can store various programs for controlling the operation of each unit of the mobile terminal 200.

  In the present embodiment, when the in-vehicle device 100 is connected via the USB communication 166, the control unit 260 executes a cooperation program that cooperates with the in-vehicle device 100. When the cooperation program is executed, the portable terminal 200 shifts to the cooperation mode, receives an instruction or a command input from the in-vehicle device 100, performs an operation corresponding to the instruction, and an audio signal or a video signal as necessary. Are transmitted to the in-vehicle device 100.

  Further, the cooperation program has a functional configuration as shown in FIG. That is, the cooperation program 270 includes an incoming call interrupt unit 280 and a communication control unit 290. When the in-vehicle device 100 is connected to the mobile terminal 200 by the USB communication 166 and the mobile terminal 200 receives an incoming call, the incoming call interrupt unit 280 interrupts and outputs the incoming information and the incoming sound via the USB communication 166. For example, if an incoming call arrives at the mobile terminal 200 while the audio signal is being transmitted from the mobile terminal 200 to the in-vehicle apparatus 100, the incoming information and the incoming sound are superimposed on the audio signal or muted and the incoming information is received. The audio signal, the incoming call information, and the incoming call sound are transmitted to the in-vehicle device 100.

  In response to the switching request transmitted from the in-vehicle device 100 based on the reception selection in the headset, the communication control unit 290 connects the wireless module of the mobile terminal 200 to the disconnected wireless modules 162 and 164 that are not selected for reception. To do. When the audio signal being played back on the mobile terminal 200 is transmitted to the in-vehicle device 100 via the USB communication 166, the audio signal is transmitted in response to the switching performed by the communication control unit 290. Playback is stopped.

Next, the headset 300 (310) will be described. FIG. 6 is an example of the external shape of the headset. The headset 300 includes a headphone 320, a microphone 330, and a reception button 340 built in the helmet. Furthermore, the headset 300 includes a wireless module, and the wireless module has an audio signal profile (for example, AVP) and a hands-free call profile (for example, HFP), and the vehicle-mounted device 100 according to the selected profile. The wireless modules 162 and 164 can be connected.
The headset 300 outputs the audio signal received via the wireless module as sound from the headphones 320 and transmits the audio signal input from the microphone 330 via the wireless module. When an incoming signal is transmitted from the in-vehicle device 100 to the headsets 300 and 310, when the reception button 340 is pressed, the signal is transmitted to the in-vehicle device 100 and detected by the reception detection unit 430 of the in-vehicle device 100.

  Next, the operation of the in-vehicle communication system according to this embodiment will be described. FIG. 7 is a connection example when the in-vehicle device 100 and the portable terminal 200 are linked in the in-vehicle communication system, FIG. 8 is a connection example when a hands-free call is performed in the in-vehicle communication system, and FIG. It is a timing chart which shows the connection state of each part.

  First, as shown in FIG. 9, when the power of the in-vehicle device 100 is turned on, the communication unit 160 searches for headsets 300 and 310 for drivers and passengers registered in advance (paired). When the search is performed, the wireless modules 162 and 164 are connected to the headsets 300 and 310. In addition, when the headsets 300 and / or 310 cannot be detected within a certain time, the wireless module 162 or the wireless module 164 may be connected to the mobile terminal 200. Furthermore, the mobile terminal 200 is connected to the in-vehicle device 100 via the USB communication 166, and both devices are placed in a state where they can operate in the cooperation mode. This connection state is shown in FIG.

  Next, for example, when an audio playback request is made from the in-vehicle device 100 to the mobile terminal 200, the mobile terminal 200 plays back the music in response to the request and the audio signal played back via the USB communication 166. Is transmitted to the in-vehicle device 100. The communication profile selection unit 420 selects the audio signal profile (for example, AVP) of the wireless modules 162 and 164, and the audio signal is transmitted to the driver's headset 300 via the wireless module 162 according to this profile. In addition, it is transmitted to the passenger's headset 310 via the wireless module 164 and is output as audio there.

  When the mobile terminal 200 receives an incoming call while the audio signal is being reproduced and output, the incoming call interrupt unit 280 interrupts the incoming call information and the incoming call sound into the audio signal, and the incoming call information and the incoming call sound are transmitted via USB communication. It is transmitted to the in-vehicle device 100 via 166.

  In the in-vehicle device 100, when incoming information is detected by the incoming information detection unit 410, the fact that there is an incoming call is displayed on the display unit 130 of the in-vehicle device 100. Further, based on the detection of incoming information, the communication profile selection unit 420 selects a profile for the hands-free call of the wireless modules 162 and 164, and an audio signal and a ring tone are transmitted to the headset 300 and the headset 310 according to the profile. Is done.

  When communication is performed using a hands-free free call profile, it is possible to select a reception by the reception button 340 of the headsets 300 and 310. FIG. 9 is an example when the answer button 340 of the headset 300 is pressed. When the reception button 340 is pressed, a pressing signal is transmitted to the in-vehicle device 100 via the wireless module 162. When the reception detection unit 430 detects the pressing signal, the switching control unit 440 causes the reception button 340 to be pressed. The connection between the headset 310 and the wireless module 164 that is not connected is disconnected, and a connection request is made to the portable terminal 200 so that the wireless module 164 and the portable terminal 200 are connected. When the wireless module 164 is connected to the mobile terminal 200, the mobile terminal 200 stops audio playback, and then a hands-free call is started. FIG. 8A shows this connection state. FIG. 8B shows a connection state when the reception button 340 of the passenger's headset 310 is pressed.

  When the hands-free call is completed, that is, triggered by the end of reception on the mobile phone 200, the wireless module of the mobile phone 200 and the in-vehicle device 100 is disconnected, and the headset 310 is searched again. A wireless connection with 310 may be established. Further, the music playback may be resumed on the mobile terminal 200 and automatically returned to the state before the hands-free call.

  FIG. 10 is an operation flow when shifting from audio reproduction to hands-free calling. When an incoming call is detected by the mobile terminal 200 (S100), incoming information and a ring tone are transmitted to the in-vehicle device 100 via the USB communication 166 (S102), and when the incoming information is detected by the in-vehicle device 100 (S102). In step S104, the profiles of the wireless modules 162 and 164 are changed from those for audio signals to those for hands-free calls, and ringtones are transmitted to the headsets 300 and 310 using the profiles for hands-free calls (S106). When the reception button 340 of the headsets 300 and 310 is pressed, a pressing signal is transmitted to the in-vehicle device 100 (S108), and the switching control unit 440 shifts to a hands-free call (S110).

  As described above, according to the present embodiment, as shown in FIG. 11, it is possible to perform audio viewing and hands-free call by the driver and the passenger by using two wireless modules without using three wireless modules. In addition, it is possible to select either the driver or the passenger to receive the call.

  In the above-described embodiment, an example in which two headsets for a motorcycle driver and a passenger are used is shown as an example. For example, even when three or more headsets are used in an interior space of an automobile or the like, a wireless module connected to a headset that is not selected for reception may be connected to the portable terminal.

  The preferred embodiment of the present invention has been described in detail above. However, the present invention is not limited to the specific embodiment, and various modifications and variations are possible within the scope of the gist of the invention described in the claims. It can be changed.
