The in-vehicle device 10, the keyless entry device 30, and the mobile terminal 20 can each perform a general operation, but in the following description, from the mobile phone 20 to the keyless entry device 30, which is unique to the present embodiment. A process of making a request for keyless entry and controlling the locking and unlocking of the door, establishing a BT connection with the portable terminal 20, and performing communication will be described.

In the vehicular communication system 1, when establishing a BT connection between the user's mobile terminal 20 and the in-vehicle device 10, the user performs keyless entry and unlocks the mobile terminal 20 that desires the BT connection, and turns on the ignition. To do. Then, the process which automatically establishes BT connection between the portable terminal 20 and the vehicle-mounted apparatus 10 is started.
Hereinafter, the scenes will be described separately.

(Keyless entry)
A keyless entry which is a premise of BT connection will be described.
As described above, in the control memory 32 of the keyless entry device 30, the terminal ID of the portable terminal 20 in which the keyless entry is recognized in advance is registered. When the user operates the operation unit 26 to instruct locking or unlocking, the operation unit 26 detects this and outputs key operation data to the control unit 21.

  In response to the key operation data, the control unit 21 starts the key operation data transmission process shown in FIG. 5A, and receives the terminal ID from the control memory 22 and the identification information (address) of the keyless entry device 30 as the instruction destination. ) IT is read, and key operation data having the identification information IT as the destination address and the terminal ID as the source address is generated (step A01).

  Next, the control unit 21 wirelessly transmits the generated key operation data from the key operation data transmission unit 25 (step A02), and ends the process.

  The key operation data receiving unit 34 of the keyless entry device 30 receives the key operation data wirelessly transmitted from the key operation data transmitting unit 25, and determines whether or not it is addressed to itself from the destination address (identification information IT). If it is addressed to itself, it receives the received key operation data and notifies the control unit 31 (outputs an interrupt signal).

  In response to the notification, the control unit 31 starts the unlocking process shown in FIG. 5B, and from the key operation data receiving unit 34, the transmission source mobile terminal 20 included in the received key operation data. The terminal ID is received and stored in the control memory 32 (step A11).

  The control unit 31 determines whether or not the received terminal ID matches one of the terminal IDs of the portable terminal 20 in which the keyless entry stored in advance in the control memory 32 is permitted (step A12). That is, the control unit 31 authenticates the request for keyless entry.

When it is determined that the received terminal ID does not match any of the terminal IDs stored in advance in the control memory 32 (step A12; No), the control unit 31 ends the current process.
On the other hand, when it is determined that the received terminal ID matches one of the terminal IDs stored in advance in the control memory 32 (step A12; Yes), the control unit 31 determines the current key (lock) state. (Step A13).
When the current state is unlocking (step A13; unlocked state), the control unit 31 transmits a control signal for performing locking to the key operation unit 33 (step A14), and ends the current process.

  On the other hand, when the current state is locked (step A13; locked state), the control unit 31 transmits a control signal for performing unlocking to the key operation unit 33 (step A15).

  The key operation unit 33 performs unlocking processing or locking processing in response to the control signal.

  After instructing unlocking in step A15, the control unit 31 waits for the power source detection unit 36 to detect ignition on (step A16). Normally, after the unlocking process, the user turns on the ignition of the vehicle 100 by turning an engine key or the like. The power supply detection unit 36 detects that the ignition is turned on and outputs a detection signal to the control unit 31.

  In response to the detection signal output from the power source detection unit 36 (step A16; Yes), the control unit 31 stores the terminal ID stored in the control memory 32 in step A11 (that is, the portable that has requested the keyless entry). Terminal ID of the terminal 20) is read out and transmitted from the terminal ID transmission unit 35 to the in-vehicle device 10 (step A17), and the current process is terminated. The control unit 31 outputs a detection signal, measures a certain time with an internal timer or the like, or communicates with the in-vehicle device 10 so that the in-vehicle device can receive the terminal ID. An ID may be transmitted.

(Establishment of BT connection)
As the ignition is turned on, supply of operating power to the in-vehicle device 10 is started, and each part of the in-vehicle device 10 starts to operate. The terminal ID receiving unit 15 of the in-vehicle device 10 that has started the operation receives the terminal ID from the keyless entry device 30 and notifies the control unit 11 of the terminal ID.

  In response to the notification from the terminal ID receiver 15, the controller 11 starts the BT connection establishment process shown in FIG. 6A, and first stores the received terminal ID in the control memory 12 (step B01). .

  The control unit 11 determines whether or not the received terminal ID matches any of the terminal IDs of the portable terminals 20 that are to be subjected to the BT connection stored in advance in the control memory 12 (step B02). That is, the control unit 11 determines whether or not the mobile terminal 20 that has performed the unlocking action is registered in advance as a target for BT connection.

  If the control unit 11 determines that the received terminal ID matches any of the terminal IDs stored in the control memory 12 (step B02; Yes), the control unit 11 determines the BT parameter corresponding to the terminal ID from the control memory 12. Read (step B03), based on the read BT parameter, send a BT connection request to the mobile terminal 20 that has performed the unlocking operation via the BT communication unit 14 (step B04), and a response from the mobile terminal 20 (Step B05).

  On the other hand, the control unit 21 of the mobile terminal 20 that has performed the unlocking operation receives the connection request from the in-vehicle device 10 by the BT communication unit 24, determines that it is addressed to itself, and performs the BT shown in FIG. The connection establishment process starts.

  First, based on the BT parameter stored in the control memory 22, the control unit 21 determines whether or not the in-vehicle device 10 that has transmitted the BT connection request is a device in which BT connection is permitted (step B11). ). That is, the device that has transmitted the BT connection request is authenticated.

When the in-vehicle device 10 that has transmitted the BT connection request determines that the BT connection is not permitted (step B11; No), the control unit 21 ends the current process. Since the vehicle-mounted device 10 cannot obtain a response within a certain time (step B5; No), the current process is terminated.
On the other hand, when the control unit 21 of the mobile terminal 20 determines that the in-vehicle device 10 that has transmitted the BT connection request is a device in which the BT connection is permitted (step B11; Yes), the control unit 21 responds to the connection request. Is transmitted (step B12).

  Thereafter, negotiation is performed between the control unit 11 of the in-vehicle device 10 and the control unit 21 of the mobile terminal 20 via the BT communication unit 14 and the BT communication unit 24 (steps B6 and B13), and the mobile device 10 and the mobile device 20 are carried. A BT connection is established between the terminals 20. This connection is a hands-free connection by HSP or HFP.

  When the BT connection is established, the control unit 11 of the in-vehicle device 10 and the control unit 21 of the mobile terminal 20 respectively display the connection completion on the display unit 17 and the display unit 27, and the audio output unit 19 The notification voice is output from the speaker 29 (steps B7 and B14), and the BT connection establishment process is terminated.

Thereafter, normal processing through the BT connection is performed. For example, the mobile terminal 20 can be connected to an external telephone, and a call can be made to the external telephone via the hands-free device 40, the in-vehicle device 10, the BT connection, and the mobile terminal 20.
In addition, the mobile terminal 20 is connected to an external server to obtain traffic information and the like, and is displayed on the display unit 17 of the in-vehicle device 10 or output from the audio output unit 18 to navigate. Is also possible.

  As described above, according to the configuration of the present embodiment, the BT connection is established only between the mobile terminal 20 that has performed the unlocking operation and the in-vehicle device 10. Therefore, the situation where BT connection is established with the portable terminal 20 of an unspecified user can be prevented, and BT connection is possible only with a user who has the intention or intention of BT connection. That is, according to the vehicle communication system 1 and the in-vehicle device 10, it is possible to establish a wireless connection with the mobile terminal 20 desired by the user. And the portable terminal 20 which performs BT connection is specified by cooperation with the keyless entry system 30 and the vehicle-mounted apparatus 10. Therefore, it is not necessary to prepare a dedicated system separately for specifying the BT connection target, and it is possible to provide a vehicular communication system that saves space and has a simple configuration and a reduced cost.

2. Second Embodiment In the first embodiment, a keyless entry is permitted for a plurality of users. In this case, the usage purpose, usage pattern, and the like of the in-vehicle device 10 vary depending on the user. In such a case, if the in-vehicle device 10 can be set to an optimum state for each user, it is convenient and convenient.

  Hereinafter, the in-vehicle device 10 that automatically performs various environment settings corresponding to the mobile terminal 20 that has performed the unlocking operation in addition to the above-described BT connection establishment processing will be described. The basic configuration and operation of the in-vehicle device 10 are the same as those in the first embodiment, and the differences will be mainly described in order to facilitate understanding.

  In this embodiment, as shown in FIG. 7, the control memory 12 of the in-vehicle device 10 matches the terminal ID of the portable terminal 20 to be connected to BT, the BT parameter, and the preference of the user who owns the portable terminal 20. The environment setting data for setting the operating environment is stored in association with each other.

  Setting targets include audio sound quality setting, playlist setting, illumination pattern setting, output sound and sound quality setting for the hands-free device 40, input sound input level setting from the hands-free device 40, and the like.

(Environment setting process)
In this embodiment, if the control part 11 of the vehicle-mounted apparatus 10 establishes BT connection by step B06 of Fig.6 (a), it will progress to step C01 shown in FIG. 8, and the environment setting data corresponding to the portable terminal 20 which carried out BT connection. Is registered in the control memory 12 in advance.

  When it is determined that the environment setting data corresponding to the mobile terminal 20 is registered (step C01; Yes), the control unit 11 reads out the environment setting data and converts various settings of the vehicle device 10 into the environment setting data. Switch to the setting based on (step C02). The process ends here.

On the other hand, when it is determined that the environment setting data corresponding to the mobile terminal 20 is not registered (step C01; No), the control unit 11 maintains the previous operating environment without performing special setting processing. The process is terminated.
According to this configuration, in addition to being able to establish a BT connection with the mobile terminal 20 desired by the user, various settings of the in-vehicle device 10 are automatically switched to preset preferences. Therefore, the user-friendly in-vehicle device 10 can be provided.

3. In the embodiment described above, the example in which the in-vehicle device 10 and the mobile terminal 20 perform wireless communication satisfying the BT specification has been shown. Communication conforming to the distance wireless communication standard is also possible.

  Although the example which connects the vehicle-mounted apparatus 10 and the keyless entry apparatus 30 with a wired cable was shown, you may connect both apparatuses wirelessly.

  Moreover, although the example which makes the vehicle-mounted apparatus 10 and the keyless entry apparatus 30 a different body was shown, the circuit of both apparatuses may be made common and integrated.

Moreover, in said embodiment, although the keyless entry apparatus 30 transferred terminal ID to the vehicle-mounted apparatus 10 only when it was unlocked, you may make it transfer irrespective of a result.
In this case, the ID of the portable terminal targeted for BT connection stored in the control memory 12 of the in-vehicle device 10 is not necessarily limited to that targeted for keyless entry and is arbitrary.

  In the embodiment described above, the keyless entry device 30 unlocks and locks the key. However, instead of unlocking and locking the key, the keyless entry device 30 may execute ignition on / off. In this case, the power source detection unit 36 does not need to detect ignition on, and the control unit 31 does not need to wait for the detection in step A16 in FIG. Further, a standby power supply may be provided to the terminal ID receiving unit 15 and the control unit 11 of the in-vehicle device 10 even while the ignition is off.

  In the present embodiment, the BT connection is established between the mobile terminal 20 that has performed the unlocking / locking operation on the vehicle 100 and the in-vehicle device 10. The present invention is not limited to this, and a BT connection may be made between the mobile terminal 20 that remotely opens and closes the window of the vehicle 100 and the in-vehicle device 10.

  Furthermore, although the keyless entry device 30 is used as means for specifying the portable terminal 20 that has operated the vehicle 100 (or indicated the intention to operate), other vehicle control devices may be used. For example, the vehicle control device may be a remote engine start device that is operated by a remote operation by the mobile terminal 20. In this case, a command to start the engine is transmitted by operating the mobile terminal 20.

  If the terminal ID is registered, the remote engine start device turns on the ignition. Start the engine and start idling. Subsequently, the terminal ID is transferred to the in-vehicle device. When determining that the terminal ID has already been registered, the in-vehicle device issues a BT connection request to the portable terminal that has instructed the engine start. Similarly, the operation instructed by the mobile terminal to the vehicle may be opening / closing a window, opening / closing a rearview mirror, and the like. In addition, a device that can remotely transmit an arbitrary command to the vehicle and a vehicle control device that can receive the command and control the vehicle are suitable for confirming the will of the user.

  In the embodiment described above, the terminal ID is received by the keyless entry device 30 and transferred to the in-vehicle device 10. However, the in-vehicle device 10 itself includes a key operation data receiving unit, and is transmitted from the portable terminal 20 to the keyless entry device 10. Depending on whether or not the terminal ID included in the key operation data is pre-registered in the control memory 12, whether or not the BT connection is performed may be controlled. In addition, the means and method itself for receiving the terminal ID of the portable terminal that has performed some operation on the vehicle are arbitrary.
