Make a call. Further, when control information indicating an incoming call to the mobile phone 4 is received via the BT communication module 59, the control unit 51 transmits to the mobile phone 4 control information instructing to respond to the incoming call. To start a call.

When this hands-free call function is executed, the navigation device 5 is connected to only one mobile phone 4 by the BT communication module 59 in principle. For this reason, when a plurality of mobile phones 4 are present in the passenger compartment 101, they are connected to any one of the mobile phones 4. Since the hands-free call function is mainly for the driver, it is desirable to connect to the mobile phone 4 possessed by the driver. Therefore, in the present embodiment, the BT communication module 59 has a function of preferentially connecting to the mobile phone 4 that has performed wireless communication with the key reader 2 to release the door lock of the vehicle 100.
That is, as described above, when the vehicle control unit 3 performs authentication based on the key information of the mobile phone 4 input via the key reader 2 and the door lock driving unit 23 unlocks the door lock, The BT address, passkey, and device name of the cellular phone 4 are acquired and stored in the memory 32. The vehicle control unit 3 transmits the BT address, the passkey, and the device name stored in the memory 32 to the navigation device 5 when the accessory power supply of the vehicle 100 is turned on and the navigation device 5 is activated. The navigation device 5 performs an operation of preferentially connecting to the cellular phone 4 based on the BT address, the pass key, and the device name received from the vehicle control unit 3. Hereinafter, this operation will be described in detail.

FIG. 4 is a flowchart showing the operation of the in-vehicle system 1 when the door lock is unlocked. In the figure, (A) shows the operation of the mobile phone 4 located outside the vehicle, (B) shows the operation of the key reader 2, and (C) shows the operation of the vehicle control unit 3.
First, as shown in FIG. 2, when a driver outside the vehicle operates the mobile phone 4 to release the door lock of the vehicle 100, a key that requests the key reader 2 to release the door lock from the mobile phone 4. The information, the BT address of the mobile phone 4, the pass key of the mobile phone 4, and the device name (device name) of the mobile phone 4 are transmitted (step S11).
The BT communication module 21 of the key reader 2 receives the key information, BT address, pass key, and device name transmitted from the mobile phone 4 (step S21), and outputs the received information to the vehicle control CPU 31 of the vehicle control unit 3. (Step S22).

The vehicle control CPU 31 of the vehicle control unit 3 receives the key information, the BT address, the pass key, and the device name input from the key reader 2 (step S31), and receives the received key information and the vehicle 100 stored in advance. Authentication based on the key information is performed by a method such as collating with the key information (step S32). Here, when authentication fails (step S33; No), vehicle control CPU31 ignores the input information and complete | finishes this process.
On the other hand, when the authentication based on the key information is successful (step S33; Yes), the vehicle control CPU 31 generates a door lock unlocking signal for instructing the door lock unlocking, and the door lock driving unit 23 of the key reader 2 is activated. (Step S34), and the BT address, pass key, and device name input from the key reader 2 are stored in the memory 32 (step S35). The vehicle control CPU 31 stands by until the accessory power supply of the vehicle 100 is turned on and the operation shown in FIG. 5 is started.

  When a door lock unlocking signal is input from the vehicle control unit 3, the door lock driving unit 23 of the key reader 2 drives the door lock actuator to unlock the door lock (step S23). As a result, the driver can board the vehicle 100, and the driver turns on the accessory power supply of the vehicle 100, whereby the operation of FIG.

FIG. 5 is a flowchart showing the operation of the in-vehicle system 1 when the navigation device 5 is activated.
When the door lock is unlocked by the operation shown in FIG. 4 and the driver gets on the vehicle 100 and turns on the accessory power or starts the engine, the accessory power of the vehicle 100 is switched on, as shown in FIG. Following the operation, the operation of FIG. 5 is started.

  In the operation shown in FIG. 5, the vehicle control CPU 31 of the vehicle control unit 3 detects that the accessory power supply has been turned on, and stores the BT address, passkey, and device of the mobile phone 4 stored in the memory 32. The name is transmitted to the navigation device 5 via the interface unit 35.

On the other hand, the navigation device 5 is started when the accessory power supply is turned on (step S41), and the control unit 51 of the navigation device 5 performs the initialization operation of each unit and the mobile phone 4 connected by the BT communication module 59. In order to detect, the connection destination registration list 67 is read from the HDD device 65 (step S42).
The control unit 51 receives the BT address, passkey, and device name transmitted from the vehicle control unit 3 via the interface unit 52 (step S43), and the received information is registered in the connection destination registration list 67. It is checked whether or not the information matches any one of the mobile telephones 4 (step S44). As a result of this verification, if the connection destination registration list 67 includes a BT address, a passkey, and a device name that match the information received from the vehicle control unit 3, the mobile phone 4 that has unlocked the door lock has already registered the connection destination. It means that it is registered in the list 67.

  If the mobile phone 4 whose door lock has been unlocked is already registered in the connection destination registration list 67 (step S45; Yes), the control unit 51 performs BT communication with the mobile phone 4 whose door lock has been unlocked. The operation detected by the module 59 is tried (step S46). When the mobile phone 4 is detected (step S47; Yes), the control unit 51 connects to the detected mobile phone 4 using a pass key, and establishes communication with the mobile phone 4. (Step S48). Thereafter, the control unit 51 executes a hands-free call function for the connected mobile phone 4 (step S49), and maintains the standby state until a call instruction or a call is received.

When the mobile phone 4 whose door lock has been unlocked is already registered in the connection destination registration list 67 (step S45; Yes), the control unit 51 uses the mobile phone 4 whose door lock has been unlocked as the connection destination. A registration process is executed (step S50). This registration process may require an operation on the mobile phone 4. In this case, the control unit 51 causes the monitor 11 to display a message for guiding registration and an operation screen for registration.
As a result of this processing, when the cellular phone 4 whose door lock has been unlocked is registered in the connection destination registration list 67, the control unit 51 proceeds to step S46.

  Further, in the operation of detecting the mobile phone 4 with the door lock unlocked by the BT communication module 59, if this mobile phone 4 is not detected (step S47; No), the connection reject setting is set in the mobile phone 4. Therefore, the control unit 51 connects to another mobile phone 4. That is, the control unit 51 tries to detect another mobile phone 4 registered in the connection destination registration list 67 in accordance with the priority order of the connection destination registration list 67 (step S51). Here, when the connectable mobile phone 4 is detected (step S52; Yes), the control unit 51 proceeds to step S48 and connects to the detected mobile phone 4.

  On the other hand, when the connectable mobile phone 4 is not detected (step S52; No), the control unit 51 does not execute the hands-free call function and starts the operation of another route guidance function or the like (step S53). This process is terminated.

  As described above, according to the in-vehicle system 1 according to the embodiment to which the present invention is applied, the BT address, the passkey, and the device name as identification information that the mobile phone 4 communicates with the mobile phone 4 outside the vehicle 100 and has. , Authenticates, and communicates with the control device 10 that unlocks the door lock of the vehicle 100 based on the authentication result, and the mobile phone 4 in the passenger compartment 101, and the BT address and pass key of the mobile phone 4 And a navigation device 5 that acquires and authenticates the device name and connects to the mobile phone 4, and the navigation device 5 preferentially connects to the mobile phone 4 authenticated by the control device 10. Even in a situation where there are a plurality of mobile phones 4 in 101, the mobile phone 4 owned and / or used by the driver is connected to the navigation device 5.In other words, since the release of the door lock of the vehicle is usually an operation performed by the driver, the mobile phone used for releasing the door lock is given priority as the mobile phone 4 to which the navigation device 5 is connected. The device 5 can be quickly and reliably connected to the mobile phone 4 possessed by the driver. For this reason, a hands-free call function can be provided to the driver without unnecessary connection.

  Further, in the in-vehicle system 1, the control device 10 of the mobile phone 4 that has been successfully authenticated and stored in the memory 32 when the accessory power source of the vehicle 100 is turned on and the navigation device 5 is turned on. The BT address, passkey, and device name are output to the navigation device 5, and the navigation device 5 searches for the mobile phone 4 having the BT address, passkey, and device name input from the control device 10 after power-on, and corresponds. When the mobile phone 4 is not detected, another mobile phone 4 is searched. Therefore, when the mobile phone 4 used for unlocking the door lock is set to refuse connection, the mobile phone 4 is used as a navigation device. When the mobile phone 4 cannot be connected, a hands-free call function can be provided to another mobile phone 4.

  Furthermore, in the in-vehicle system 1, the navigation device 5 associates the BT address, passkey, and device name of the mobile phone 4 registered in advance in the connection destination registration list 67 as the connection destination with the priority order, and the connection destination registration list 67. When the mobile phone 4 having the BT address, the passkey, and the device name input from the control device 10 after power-on is searched and the corresponding mobile phone 4 is not detected, Since other mobile phones 4 registered in the connection destination registration list 67 are searched according to the priority order registered in the connection destination registration list 67 in association with the BT address, passkey, and device name, a person other than the driver can search. The mobile phone 4 that is owned or used can be connected according to priority.

The above-described embodiment is merely one aspect of the present invention, and can be arbitrarily modified within the scope of the present invention. For example, only the BT address may be acquired and transmitted / received as identification information for identifying the mobile phone 4, and the mobile phone 4 may be identified based on the BT address. Moreover, in the said embodiment, although the vehicle control unit 3 shall authenticate for unlocking a door lock based on the key information which the mobile telephone 4 transmitted, this invention is limited to this. Instead, the BT address or pass key may be used for authentication of door lock unlocking. Further, in addition to the key information, more complicated authentication information may be transmitted and received between the mobile phone 4 and the key reader 2.
Moreover, in the said embodiment, when the navigation apparatus 5 starts and searches the mobile telephone 4, and when the mobile telephone 4 which can be connected by this search is not detected, it waits only for predetermined time, and performs a search again. Alternatively, the search operation may be continued for a predetermined time. Then, after a predetermined time elapses, another mobile phone 4 registered in the connection destination registration list 67 may be searched, and the detailed configurations of the other key reader 2, the vehicle control unit 3, and the navigation device 5 are arbitrary. Can be changed.

  In the above embodiment, the navigation device 5 has been described as an example of an in-vehicle device that provides a hands-free call function. However, the present invention is not limited to this, and a BT communication module, an audio processing unit, a speaker, and The present invention can also be applied as a configuration in which a hands-free communication device having only a microphone is provided in the in-vehicle system 1 instead of the navigation device 5. In addition, the function provided by the in-vehicle device connected to the mobile phone 4 is not limited to the hands-free call function.
