  A mobile phone having a BT communication function is brought into a vehicle interior of a vehicle on which an in-vehicle device having a Bluetooth (registered trademark) (hereinafter referred to as BT) communication function is mounted, and the in-vehicle device and the mobile phone can perform BT communication. When a mail incoming from the communication network to the mobile phone occurs in a state where the vehicle is in operation, a configuration is disclosed in which the incoming mail is notified from the in-vehicle device after the vehicle operation is stopped without notifying the incoming mail from the in-vehicle device during driving of the vehicle ( For example, see Patent Document 1).

JP 2003-256341 A

  By the way, the main use of the mobile phone in the vehicle interior is hands-free calling, and there is a hands-free profile (HFP) for realizing hands-free calling defined by the BT communication standard. Here, when the HFP is connected between the mobile phone and the in-vehicle hands-free device, the hands-free call state in which the user makes a call using the microphone and the speaker on the in-vehicle hands-free device side is used. And a handset call state in which a call is made using a microphone and a speaker of a mobile phone. The user selects a hands-free call if there is no problem even if the passenger hears the call content (especially the voice received from the other party), while the caller may hear the call content. In some cases, it is assumed that a handset call is selected.

  Under such circumstances, the applicant is considering a configuration in which MAP and HFP are simultaneously connected between the in-vehicle hands-free device and the mobile phone. Here, when an incoming mail from the communication network to the mobile phone occurs when the user selects the hands-free call state, the incoming mail to the mobile phone is notified from the mobile phone to the in-vehicle hands-free device by the MAP, An incoming mail notification sound is output from the in-vehicle hands-free device, and the user can recognize the incoming mail by listening to the incoming mail notification sound. On the other hand, if the user selects the handset call state and a mail arrives from the communication network to the mobile phone, the mail arrives from the communication network to the mobile phone when the user selects the hands-free call state. In the same way as when it occurs, a mail incoming notification sound is output from the in-vehicle hands-free device, and the user can recognize the incoming mail by listening to the mail incoming notification sound.

  However, if the user has selected the handset call state, considering that there is basically a situation in which privacy is to be ensured, an incoming mail notification sound is output from the in-vehicle hands-free device and the incoming mail is a passenger other than the user. However, it is contrary to the user's intention to ensure privacy, which is not preferable.

When the mail arrival determination means determines that the mobile phone connected to the transfer protocol has received mail, and the state determination means determines that the mobile phone that has received the mail has selected the handset call state, the mail arrival notification is sent. Do not do to user.

  As a result, if the mobile phone is in a handset call state and an e-mail is received, the user's privacy can be reliably ensured by not performing the e-mail notification to the user, thereby impairing the user's intention. Can be dealt with appropriately without any problems.

  According to the in-vehicle device with the hands-free function according to claim 4, the control means determines that the mail incoming determination means determines that the mobile phone connected to the mail transfer protocol with the connection means has received the mail, After the state determination means determines that the mobile phone that received the mail has selected the handset call state, the state determination means determines that the mobile phone that has received the mail has switched from the handset call state to the hands-free call state. Then, mail notification is sent to the user.

  Thereby, the user can recognize the incoming mail after the mobile phone is switched from the handset call state to the handsfree call state by performing an operation of switching the handset call to the handsfree call.

  According to the in-vehicle device with the hands-free function according to claim 5, the control means determines that the mail incoming determination means determines that the mobile phone connected to the mail transfer protocol with the connection means has received the mail, After the state determination means determines that the mobile phone that received the mail has selected the handset call state, the state determination means determined that the mobile phone that received the mail has switched from the handset call state to the standby state. In this case, a mail incoming notification is sent to the user.

  Thus, the user can recognize the incoming mail after the mobile phone is switched from the handset call state to the standby state by performing an operation for ending the handset call.

  According to the in-vehicle device with the hands-free function according to claim 6, the control means outputs from the voice output means on the in-vehicle device side with the hands-free function when the mobile phone that has received the mail selects the hands-free call state.

Yes.

  As a result, when the mobile phone is in the standby state, the volume of the incoming mail notification sound is high, so that the user can be sure that the incoming mail is recognized. On the other hand, when the mobile phone is in the hands-free call state, the incoming mail notification Although the volume of the sound is low, the user can recognize the incoming mail, but the influence on the received voice of the hands-free call can be suppressed, and the incoming voice of the hands-free call becomes difficult to hear with the incoming mail notification sound. Can be avoided.

  According to the mobile phone described in claim 7, a hands-free call protocol for realizing a hands-free call and a mail transfer protocol for realizing mail transfer can be simultaneously connected to an in-vehicle device with a hands-free function. Configured to be connected to the hands-free in-vehicle device with the hands-free function in a state where the hands-free call protocol is connected, Between a hands-free call state and an in-vehicle device with a hands-free function, which is transmitted as a transmitted voice to the other party and is output as a received voice from a voice output means on the in-vehicle device with the hands-free function. The voice path is closed and the voice input by the voice input means is sent to the other party as the transmission voice. Can be selected from the handset call state in which the voice received and received from the other party is output as the received voice from the voice output means of the own device, and a hands-free call protocol between the in-vehicle device with a hands-free function and When the mail transfer protocol is connected at the same time and the machine receives a mail when the machine is set to the hands-free call state, it notifies the in-vehicle device with a hands-free function that the mail has arrived, and the machine itself makes a handset call. If a mail is received while the status is set, the in-vehicle device with a hands-free function is not notified that the mail has been received.

  As a result, if an incoming mail is received when the device is in the handset call state, the operation of notifying the incoming mail by not notifying the in-vehicle device with a handsfree function that the incoming mail has been received is hands-free. In the same manner as described in claim 3 above, the user's privacy can be reliably ensured and appropriately dealt with without impairing the user's intention. be able to.

  Next, the operation of the above configuration will be described with reference to FIGS. FIG. 5 is a flowchart showing processing performed by the in-vehicle hands-free device 2. In the in-vehicle hands-free device 2, the control unit 4 starts mail incoming detection processing for determining whether or not an incoming mail from the communication network 18 to the mobile phone 3 has occurred. It is determined whether an incoming call has occurred (step S1). If the control unit 4 determines that no incoming mail has occurred from the communication network 18 to the mobile phone 3 (“NO” in step S1), the control unit 4 ends the incoming mail detection process and performs other processing ( For example, the process returns to the main process.

  When the control unit 4 determines that an incoming mail from the communication network 18 to the mobile phone 3 has occurred by inputting a mail incoming notification from the mobile phone 3 ("YES" in step S1), the mobile phone 3 It is determined whether or not the cellular phone 3 that has received an e-mail is in a hands-free call state, a private call state, or a standby state (a state in which a voice call is awaited) by inputting a state notification from (Steps S2, S3).

  Here, when the control unit 4 inputs a status notification from the mobile phone 3 and determines that the mobile phone 3 that has received the e-mail is in the standby state, not in either the hands-free call state or the private call state (step S2). "NO" at S3, "NO" at S3), a mail incoming notification screen indicating that a mail has been received pops up on the standby screen, and at the same time, a mail incoming notification sound indicating that a mail has been received is displayed on the speaker 12, 13 (step S4). That is, as shown in FIG. 6, the control unit 4 causes the display device 16 to display a route guidance screen 22 (a screen in which the current vehicle position is superimposed on the map screen) 22 during the route guidance as a standby screen. If the mobile phone 3 receives a mail while the mobile phone 3 is receiving a mail, the mail incoming notification screen 23 is displayed in a pop-up on the route guidance screen 22 which is a standby screen. Thus, the user can visually recognize the incoming mail in real time by looking at the incoming mail notification screen 23 pop-up displayed on the route guidance screen 22, and the incoming mail notification sound output from the speakers 12 and 13. Listening to can audibly recognize incoming mail in real time.

  When the control unit 4 determines that the mobile phone 3 receiving the mail is in a hands-free call state by inputting a status notification from the mobile phone 3 ("YES" in step S2), it indicates that the mail has been received. A mail incoming notification screen is displayed on the hands-free call notification screen while a mail incoming notification sound indicating that a mail has been received is output from the speakers 12 and 13 (step S5). That is, if the mobile phone 3 receives a mail when the hands-free call notification screen 20 shown in FIG. 3 is displayed on the display device 16 as shown in FIG. The incoming call notification screen 24 is popped up on the hands-free call notification screen 20. Accordingly, the user can visually recognize the incoming mail in real time by looking at the incoming mail notification screen 24 pop-up displayed on the hands-free call notification screen 20, and the mail output from the speakers 12 and 13. By listening to the incoming call notification sound, incoming mail can be recognized audibly in real time.

  The control unit 4 sets the volume of the incoming mail notification sound that is output when the mobile phone 3 is in the hands-free call state to be lower than the volume of the incoming mail notification sound that is output when the mobile phone 3 is in the standby state. It is set. That is, for example, when the volume of the incoming mail notification sound to be output when the user is in a standby state is manually set, the control unit 4 has a volume lower than the set volume in the hands-free call state. Automatically set the volume of the incoming mail notification sound to be output to. On the other hand, when the volume of the incoming mail notification sound to be output when the user is in the hands-free call standby state is manually set, for example, the control unit 4 increases the volume higher than the set volume. It is automatically set as the volume of the incoming mail notification sound to be output when in standby mode.

  Further, when the control unit 4 determines that the mobile phone 3 receiving the mail is in a private call state by inputting a status notification from the mobile phone 3 ("YES" in step S3), it indicates that the mail has been received. The mail incoming notification screen is pop-up displayed on the private call notification screen. In this case, the mail incoming notification sound indicating that the mail has been received is not output from the speakers 12 and 13 (step S6). That is, if the mobile phone 3 receives a mail while the private call in-call notification screen 21 shown in FIG. 4 is displayed on the display device 16, the control unit 4 receives the mail as shown in FIG. The notification screen 25 is pop-up displayed on the private call notification screen 21, but the mail incoming notification sound is not output from the speakers 12 and 13. As a result, the user can visually recognize the incoming mail visually in real time by looking at the incoming mail notification screen 25 pop-up displayed on the private call notification screen 21, and the incoming mail notification screen 25 is displayed. It is possible to make it difficult for passengers other than the user to notice the incoming mail by not outputting the incoming mail notification sound.

  As described above, according to the first embodiment, in the in-vehicle hands-free device 2, when the HFP and MAP are connected to the mobile phone 3, the mobile phone 3 that has received an e-mail has received a hands-free call. If it is in the state, the mail incoming notification screen 24 is displayed on the display device 16 or the mail incoming notification sound is output from the speakers 12 and 13. On the other hand, if the mobile phone 3 receiving the mail is in the private call state, Since the mail incoming notification sound is not output from the speakers 12 and 13 simply by displaying the mail incoming notification screen 24 on the display device 16, it is difficult for passengers other than the user to notice the incoming mail, and the user's privacy is improved. It can be ensured, and can be appropriately handled without impairing the user's intention.

  Also, since the volume of the incoming mail notification sound that is output when the mobile phone 3 is in the hands-free call state is set lower than the volume of the incoming mail notification sound that is output when the mobile phone 3 is in the standby state, When the telephone 3 is in the standby state, the volume of the incoming mail notification sound is high, so that the user can be surely recognized that the incoming mail is received. On the other hand, when the mobile telephone 3 is in the hands-free call state, Although the volume is low, the user can recognize the incoming mail, but the influence on the received voice of the hands-free call can be suppressed, and it is avoided that the incoming voice of the hands-free call becomes difficult to hear with the incoming mail notification sound. can do.
