[0012]
Signal transmission / reception performed between the above-described in-vehicle system of the incoming call guidance apparatus and the mobile telephone 11 will be described. FIG. 3 is a diagram for explaining an outline of communication performed between the control unit 2 and the control unit 101 of the mobile telephone 11 and between the control unit 2 and the input / output control unit 3. In FIG. 3, the left side represents the input / output control unit 3, the center represents the control unit 2, and the right side represents the control unit 101 of the mobile telephone 11. Also, the vertical direction in FIG. 3 represents time, and the time proceeds downward in FIG. 3 as time elapses. The arrows with # in the figure indicate the flow of each signal. The signals shown in FIG. 3 are extracted from the main parts for easy understanding, and do not describe all the actual signal flows.
[0013]
In # 10 of FIG. 3, the control unit 2 periodically transmits a connection confirmation signal, for example, at intervals of 10 seconds via the wireless communication interface 21. The transmission power in this case is a transmission power enough to reach the mobile telephone 11 in the vehicle. When receiving the connection confirmation signal via the wireless communication interface 101a, the control unit 101 of the mobile telephone 11 transmits the confirmation response signal to the in-vehicle system via the wireless communication interface 101a in # 11. The control unit 2 detects that the mobile telephone 11 has been brought into the vehicle by receiving the confirmation response signal via the wireless communication interface 21.
[0014]
In # 20, the control unit 2 transmits a signal requesting the owner ID and a ring tone volume control signal to the mobile telephone 11. When receiving the ring volume control signal, the control unit 101 of the mobile telephone 11 outputs a control command to the input / output control unit 104 so as to lower the ring tone reproduction volume. As a result, the incoming call volume is reduced to a level that is not noticed by the driver. When receiving the ID request signal, the control unit 101 transmits an ID response signal to the in-vehicle system in # 21, reads out the owner ID from the memory 102, adds the ID to the ID response signal, and transmits it to the in-vehicle system. The control unit 2 stores (registers) the received owner ID in the memory 1. As a result, the owner ID of the mobile telephone 11 brought into the vehicle is stored in the memory 1 as a database. The database includes audio data and display data.
[0015]
Here, if the correspondence information between the owner ID and the owner name is stored in the memory 1 in advance, the audio data in the database becomes data for reproducing the owner name. The display data is display data for displaying the owner name. When the correspondence information between the owner ID and the owner name is not stored in the memory 1 in advance, the audio data and the display data are data for reproducing and displaying the owner ID, respectively.
[0016]
In # 210, when there is an incoming call to the mobile telephone 11, an incoming signal is sent from the transmission / reception part 103 to the control part 101 of the mobile telephone 11. In step # 30, the control unit 101 transmits an incoming call notification signal, that is, an owner ID to the in-vehicle system. When receiving the incoming call notification signal, the control unit 2 transmits a response signal to the mobile telephone 11 at # 31. The control unit 101 of the mobile telephone 11 confirms that the mobile telephone 11 is in the vehicle by receiving the response signal. On the other hand, when the response signal is not received, the control unit 101 of the mobile telephone 11 considers that the mobile telephone 11 has been taken out of the vehicle. Also, when the connection confirmation signal cannot be received for a predetermined time or longer, it is considered that the mobile telephone 11 has been taken out of the vehicle. When the mobile telephone 11 is taken out of the vehicle, the control unit 101 outputs a control command to the input / output control unit 104 so as to restore the ring tone reproduction volume.
[0017]
When the control unit 2 transmits a response signal to the mobile telephone 11 in # 31 described above, the control unit 2 collates the incoming notification signal with the owner ID registered in the database in the memory 1. As a result of the collation, when the received incoming call notification signal matches the registered owner ID, the control unit 2 reads voice data and display data corresponding to the owner ID from the database. In # 110, the control unit 2 sends an audio output command and audio data to the input / output control unit 3 so as to reproduce the read audio data from the speaker 5. Thereby, for example, the incoming call guidance “Call Mr. XX” is reproduced from the speaker 5. In step # 120, the control unit 2 sends a display output command and display data to the input / output control unit 3 so that the read display data is displayed on the display 4. As a result, for example, an incoming call guidance “Call Mr. XX” is displayed on the display 4. When an incoming call to the mobile telephone 11 is notified, if the owner of the telephone is a driver, a hands-free call is performed, and if the owner of the telephone is a passenger, the telephone is answered and a call is performed.
[0018]
Even when the incoming call notification signal is not sent from the mobile telephone 11 in which the owner ID is registered, the control unit 2 periodically transmits a connection confirmation signal to the mobile telephone 11 at intervals of 10 minutes, for example. When receiving the connection confirmation signal, the control unit 101 of the mobile telephone 11 transmits a confirmation response signal to the in-vehicle system. When the confirmation response signal is received, the control unit 2 confirms that the mobile telephone 11 is in the vehicle. When the confirmation response signal is not received, the control unit 2 considers that the mobile telephone 11 has been taken out of the vehicle, and deletes the owner ID registered in the memory 1.
[0019]
On the other hand, when the periodic response signal from the control unit 2 is not received, the control unit 101 of the mobile phone 11 considers that the mobile phone 11 has been taken out of the vehicle due to timeout determination. In this case, the control unit 101 outputs a control command to the input / output control unit 104 so as to restore the ring tone reproduction volume.
[0020]
When the mobile phone brought into the vehicle is set to the manner mode so as not to ring the incoming call, the above-described incoming call guidance may not be performed. By preventing the telephone set in the manner mode from transmitting the confirmation response signal to the connection confirmation signal transmitted from the control unit 2, the above-described incoming call guidance for the telephone is not performed. In addition, when the manner mode of the telephone set to the manner mode in the vehicle is canceled, the telephone transmits a confirmation response signal to the connection confirmation signal transmitted from the control unit 2. Incoming call guidance for the telephone is performed. As described above, the incoming call guidance described above is performed so that the driver's attention is not distracted by the incoming call sound when the mobile telephone set to ring the incoming call is brought into the vehicle.
[0021]
In the above description of FIG. 3, the mobile phone 11 has been described as an example, but the same applies to the mobile phone 12. When a plurality of mobile telephones are brought into the vehicle, the communication from the connection confirmation signal of # 10 to the reception of the ID response signal and ID of # 21 is performed with each mobile telephone in FIG. The owner ID of each mobile phone is registered in order. When a plurality of mobile phones are brought into the vehicle and a plurality of owner IDs are registered, the control unit 2 identifies and notifies which mobile phone has received an incoming call by an incoming notification signal (owner ID). To do.
[0022]
According to the embodiment described above, the following operational effects can be obtained.
(1) The control unit 2 of the in-vehicle system periodically sends a connection confirmation signal to the inside of the vehicle, and the mobile telephone 11 sends a confirmation response when receiving the connection confirmation signal in a range where the connection confirmation signal can be received. . Thereby, the control part 2 of a vehicle-mounted system can detect that the mobile telephone 11 was brought into the vehicle.
(2) When the mobile telephone 11 is brought into the vehicle, the control unit 2 registers the owner ID of the mobile telephone 11 in the database in the memory 1 and reduces the ringing volume when the mobile telephone 11 is received. Since it did in this way, it becomes possible for a driver | operator to drive in comfort, without worrying about a ringtone during driving | operation.
(3) When the mobile telephone 11 receives an incoming call, it sends an incoming call notification signal (owner ID) to the in-vehicle system, and the control unit 2 of the in-vehicle system collates the sent owner ID with the owner ID registered in the database. To do. If they match as a result of the collation, the incoming call guidance “Call me Mr. XX” is reproduced from the speaker 5, and the incoming call guidance “Call me Mr. XX” is displayed on the display 4. Therefore, the incoming call guidance is performed even if the ring volume is reduced, so that the convenience of the telephone can be maintained.
(4) Since the mobile phone 11 sends the owner ID to the control unit 2 as an incoming notification signal, the control unit 2 has a plurality of mobile phones brought into the vehicle, and a plurality of owner IDs are registered. Even in this case, it is possible to identify and notify which mobile telephone has received an incoming call by an incoming call notification signal.
[0023]
In the above description, when the control unit 101 of the mobile telephone 11 receives the ring volume control signal, the control command is output to the input / output control unit 104 so as to lower the ring tone reproduction volume. The control command may be output so that the sound reproduction volume is 0, that is, the ringtone is turned off.
[0024]

However, the incoming call guidance can also be applied to receiving data such as mail. Also in this case, when a mobile telephone set to ring an incoming sound is brought into the vehicle, the incoming call volume is reduced. When there is an incoming data to the mobile phone, the mobile phone sends an incoming notification signal to the in-vehicle system and receives the data. When the received incoming notification signal matches the registered owner ID, the control unit 2 of the in-vehicle system, for example, causes the speaker 5 to reproduce the incoming call guidance “A mail has been delivered to Mr. XX”. In addition, for example, an incoming call guidance “A mail has arrived at Mr. XX” is displayed on the display 4. Thereby, when the owner of the mobile phone is a driver, if the vehicle is running, the content of the received data such as an e-mail is confirmed after the vehicle is stopped. In addition, when the owner of the mobile phone is a passenger, the contents of received data such as e-mail are confirmed as necessary.
[0025]
In the above description, the correspondence information between the owner ID and the owner name of the mobile phone 11 is stored in the memory 1 by operating the operation unit 6, but is stored in the memory 102 of the mobile phone 11. The transmitted data may be sent to the control unit 2 via the wireless communication interface 101a, and the sent data may be stored in the memory 1.
