Each of the in-vehicle device 10, the keyless entry device 30, and the mobile terminal 20 can perform a general operation.

  In the following description, a BT connection is established between the portable terminal 20 of the occupant of the vehicle 100 and the in-vehicle device 10 that is unique to the present embodiment, and the in-vehicle device 10 can be operated by each portable terminal 20. A characteristic operation of not accepting an operation from the mobile terminal 20 used for keyless entry (unlocking) will be described.

  Hereinafter, specific scenes will be described separately.

(Keyless entry)
The keyless entry will be described.
As described above, in the control memory 22 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 of the portable terminal 20 in which the keyless entry is recognized in advance 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 keyless entry process shown in FIG. 6A, and from the control memory 22, its own terminal ID and identification information (address) IT of the keyless entry device 30 that is the instruction destination. And the 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 keyless entry process shown in FIG. 6B, 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 12a 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.

  If the control unit 31 determines that the received terminal ID does not match any of the terminal IDs 12a of the portable terminals 20 for which keyless entries stored in advance in the control memory 32 are permitted (step A12; No), this time Terminate the process.

  On the other hand, when the control unit 31 determines that the received terminal ID matches one of the terminal IDs 12a of the portable terminal 20 in which the keyless entry stored in advance in the control memory 32 is permitted (step A12; Yes). The current key (lock) state is discriminated (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). The key operation unit 33 locks the vehicle 100 in response to the control signal, 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 an unlocking process 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.

  If the ignition is not turned on after waiting for a certain time in step A16, the key is locked again and the process is terminated.

  Subsequently, the control unit 31 obtains the terminal ID stored in the control memory 32 in Step A11 (that is, the terminal ID of the mobile terminal 20 that has requested the keyless entry) and the unlocking information indicating that the unlocking has been performed. The included key control information is transmitted from the terminal ID transmitter 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 predetermined time by an internal timer or the like, or transmits a data transmission request signal to the in-vehicle device 10, and the in-vehicle device 10 responds to it from the in-vehicle device 10. When the permission signal is returned, the terminal ID and the unlock information may be transmitted.

  On the other hand, along with the ignition being 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 key control information including the terminal ID and the unlocking information transmitted by the keyless entry device 30 in step A17, and provides the control unit 11 with the key control information.

  In response to receiving control information including the terminal ID and unlocking information, the control unit 11 starts the terminal ID registration process shown in FIG. First, the control unit 11 stores a BT parameter corresponding to the terminal ID included in the received control information (a BT parameter necessary for BT connection with the mobile terminal 20 used for the unlocking operation) in the control memory 12. Is identified from the pair 12a of the terminal ID and BT parameter of the portable terminal in which the keyless entry stored in is recognized (step A21). Subsequently, the pair of the terminal ID (terminal ID of the mobile terminal 20 used for unlocking) included in the received control information and the BT parameter for the mobile terminal 20 specified in step A21 is used for unlocking. The terminal ID and BT parameter pair 12c of the portable terminal 20 is registered in the control memory 12 (step A22), and the process is terminated. If the previously stored terminal ID / BT parameter pair 12c remains, it is overwritten.

(Establishment of BT connection)
Moreover, the vehicle-mounted apparatus 10 will perform the BT connection establishment process shown to Fig.8 (a), if operating power is supplied.

  First, the control unit 11 transmits a BT connection request to surrounding mobile terminals 20 via the communication unit 14 (step B01), and waits for a response from the mobile terminal 20 (step B02).

  On the other hand, the control unit 21 of the mobile terminal 20 in the vehicle 100 receives the BT connection request from the in-vehicle device 10 by the communication unit 24, and starts the BT connection establishment process shown in FIG.

  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. The in-vehicle device 10 returns to step B01 when no response is obtained within a certain time (step B02; No).

  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). This response includes the terminal ID of the mobile terminal 20 that transmits the response.

  On the other hand, the control unit 11 of the in-vehicle device 10 receives a response from the mobile terminal 20 via the communication unit 14 (step B02; Yes), and the mobile terminal 20 that has responded is the mobile terminal 20 that is recognized as BT connection. Whether or not there is is determined based on the terminal ID and BT parameter pair 12b stored in advance in the control memory 12 (step B03).

  When it is determined that the mobile terminal 20 that has responded is not the mobile terminal 20 to which the BT connection is permitted (step B03; No), the process returns to step B01.

  On the other hand, when it is determined that the mobile terminal 20 that has responded is the mobile terminal 20 in which the BT connection is permitted (step B03; Yes), the control unit 11 of the in-vehicle device 10 and the control unit 21 of the mobile terminal 20 In the meantime, negotiation is performed via the communication unit 14 and the communication unit 24 (steps B04 and B13), and a BT connection is established between the in-vehicle device 10 and the portable terminal 20, and corresponding settings are performed.

  For example, when HSP (Headset Profile) and HFP (Hands-Free Profile) are set as BT parameters between the in-vehicle device 10 and a specific mobile terminal 20 to realize a hands-free call, the in-vehicle device 10 When the BT connection is established, the specific mobile terminal 20 performs various settings so that communication can be transmitted / received and a call can be made via the hands-free device 40.

  The control unit 11 of the in-vehicle device 10 and the control unit 21 of the mobile terminal 20 display a connection completion message on the display unit 17 and the display unit 27, respectively, when necessary, when the BT connection is established. A notification voice is output from the voice output unit 18 and the speaker unit 29.

  Thereafter, the process returns to step B01, and the BT connection is sequentially established with the surrounding mobile terminal 20 in which the BT connection is previously approved. In addition, after the BT connection is established, when there is a mobile terminal 20 that cannot perform BT communication for a certain time or longer, the BT connection with the mobile terminal 20 is disconnected.

Thereafter, various processes are performed via the BT connection.
In addition, the request | requirement of BT connection from the portable terminal 20 side to the vehicle-mounted apparatus 10, and the subsequent BT connection process are also performed suitably.

  Here, when operating (controlling) the in-vehicle device 10 using the portable terminal 20 that has established a BT connection with the in-vehicle device 10, the user stores the control memory 22 by a predetermined key operation or the like. An operation program (a program for controlling various functions of the in-vehicle device 10 via the BT connection) is activated. Note that the operation program may be automatically activated in response to the establishment of the BT connection (step B13).

  By starting the operation program, the control unit 21 of the mobile terminal 20 starts the operation process shown in FIG. 9A, and first determines whether or not any operation has been performed (step C01). When it is determined that there is no operation (step C01; No), step C01 is repeated to wait for an operation input by the user.

  On the other hand, when it is determined that there is an operation (instruction) (step C01; Yes), the control unit 21 receives control information including operation information indicating the content of the operation (instruction) and control information including information identifying the terminal itself. Then, the data is transmitted to the in-vehicle device 10 via the communication unit 24 (step C02). The operation information may be, for example, information indicating a key operation itself such as an operation of the right cursor, or may indicate contents of processing instructed by the key operation. Thereafter, it is determined whether or not the process has been completed (step C03). If not completed (step C03; No), the process returns to step C01 and the above-described process is repeated. On the other hand, when it is determined that the process is finished (step C03; Yes), the current process is finished.

  The control unit 11 of the in-vehicle device 10 receives the control information (operation information + own terminal identification information) transmitted in step C02 via the communication unit 14, and starts the operation process illustrated in FIG. 9B.

  First, the control unit 11 uses whether or not the mobile terminal 20 that has transmitted the control information is the mobile terminal 20 used for unlocking (keyless entry) for unlocking stored in the control memory 12. A determination is made based on the terminal ID and BT parameter pair 12c of the mobile terminal that has been made (step C11).

  When the BT parameter of the portable terminal 20 used for unlocking is not stored in the control memory 12 (when unlocking is performed other than keyless entry), the control unit 11 and the portable terminal 20 that has transmitted control information If the BT parameter during the period does not match the BT parameter of the mobile terminal used for unlocking stored in the control memory 12 (step C11; No), the mobile terminal 20 that has transmitted the control information is used for unlocking. Therefore, the process according to the operation represented by the received control information is executed (step C14).

  On the other hand, when the BT parameter with the mobile terminal 20 that has transmitted the control information matches the BT parameter of the mobile terminal used for unlocking stored in the control memory 12 (Step C11; Yes), since the mobile terminal 20 that has transmitted the control information is the mobile terminal 20 used for unlocking, the operation specified by the operation information included in the received control information is targeted for the permitted functions. Whether or not the operation is performed is determined with reference to the operation permission / prohibition table (FIG. 3) 12d stored in the control memory 12 shown in FIG. 2 (step C12).

  If the operation is a function that is permitted (step C12; Yes), for example, if the operation corresponding to the operation information is on the data recorder function, the operation permission / prohibition table 12d in FIG. Since the operation is permitted, Yes is determined in step C12, and the recorder function is turned on in step C14.

  If the operation is a prohibited function (step C12; No), for example, if the operation corresponding to the operation information is the setting of the destination of the car navigation or the adjustment of the audio volume, the operation permission / In the prohibition table 12d, since the operation of the car navigation function and the audio function is prohibited, it is determined No in Step C12, and a warning as illustrated in FIG. 10 is displayed on the display unit 17 in Step C13, for example. This processing is terminated.

  As described above, in the present embodiment, it can be set to prohibit the operation of the in-vehicle device 10 using the mobile terminal 20 used for keyless entry (unlocking). Accordingly, since keyless entry, particularly unlocking, is often performed by the driver, operations that are not preferably performed by the driver can be efficiently prohibited with a simple configuration and with few malfunctions.

In addition, this invention is not limited to the said embodiment, A various deformation | transformation and application are possible.
For example, in the operation permission / prohibition table 12d shown in FIG. 3, permission / prohibition is set for each of the major categories (basic functions) of the functions of the in-vehicle apparatus 10, but as shown in FIG. Permit / Prohibit may be set. In addition to the items shown in FIGS. 3 and 11, permission / prohibition control may be performed. For example, permission / prohibition control may be performed on the function in the mobile terminal operation itself, use restriction of telephone call / internet browsing by operation of the mobile terminal, start-up / use restriction of entertainment application, or the like may be performed. Further, a restriction that prohibits transfer of video data may be performed.

2. Second Embodiment In the first embodiment, the in-vehicle device 10 is provided on condition that the mobile terminal 20 that has transmitted the control information is the mobile terminal 20 used for keyless entry (unlocking) ( Step C11; Yes), it is determined whether the operation represented by the operation information included in the control information is permitted or prohibited (Step C12). The present invention is not limited to this, and any other condition may be added as a condition for determining whether it is permitted or prohibited.

  For example, as shown in FIG. 12, when it is determined that the mobile terminal 20 that has transmitted the control information is the mobile terminal 20 used for keyless entry (unlocking) (step C11: Yes), It is determined whether or not the mobile terminal 20 is in a call state (step C21). When the mobile terminal 20 is in a call state (step C21; Yes), whether or not the operation represented by the operation information included in the control information is permitted / prohibited It may be configured so as to determine whether it has been performed (step C12).

  Here, being in a call state is not limited to a state in which the mobile terminal 20 is actually used for a call. For example, in a state where the mobile terminal 20 and the in-vehicle device 10 are BT-connected based on HSP (Headset Profile) and HFP (Hands-Free Profile) for realizing hands-free calling, the hands-free device 40 is used. Thus, a call can be made using the portable terminal 20 as necessary.

  Therefore, it is desirable to determine that the mobile terminal 20 and the in-vehicle device 10 are BT-connected in a state where communication is possible, as a call state.

  According to this configuration, when the mobile terminal 20 is used for keyless entry (unlocking) and is in a normal state, a predetermined operation process is prohibited, so that a truly undesirable operation such as a driver can be prohibited. Thus, it is possible to prevent a situation where even operations that are not harmful are uniformly prohibited.

3. Third Embodiment In the second embodiment, assuming that the mobile terminal 20 is the mobile terminal 20 used for keyless entry (unlocking) (step C11; Yes), as other conditions, When the mobile terminal is in a call state (step C21; Yes), it is determined whether the operation represented by the operation information included in the received control information is permitted or prohibited (step C12). However, for example, it is not necessary to uniformly prohibit the operation using the mobile terminal 20 until the vehicle 100 is stopped and it is clear that the driver is not driving.

  Therefore, as shown in FIG. 13A, when it is determined in the process of step C21 that the telephone is in a call state (step C21; Yes), the vehicle speed is determined from the output of the vehicle speed sensor in the sensor group 201. (Step C22) When the vehicle speed is 0 (ie, stopped state) (Step C22; Yes), processing based on the operation information is permitted (Step C14), and when the vehicle speed is other than 0 (ie, running state) (Step C22). No) may determine whether processing based on the operation information is permitted or prohibited (step C12).

Further, as shown in FIG. 13B, step C21 can be skipped.
In step C22, instead of determining whether the vehicle speed is strictly 0, it is determined whether the vehicle speed is a predetermined speed, for example, about 3 km / hour or less (the vehicle speed can be substantially regarded as 0). Also good.

Further, as shown in FIG. 14A, when it is determined in the process of step C21 that the telephone is in a talking state (step C21; Yes), the driver determines from the output of the steering touch sensor in the sensor group 201. It is determined whether or not the steering wheel is touched (step C23), and when the steering wheel is not touched (that is, not driving) (step C23; No), it is based on the operation information included in the received control information. When processing is permitted and the steering wheel is touched (that is, driving) (step C23; Yes), it is determined whether processing based on the operation information is permitted or prohibited (step C12). Also good.
Further, as shown in FIG. 14B, step C21 can be skipped.

  Further, as shown in FIG. 15A, when it is determined in the process of step C21 that the telephone is in a talking state (step C21; Yes), the driver is seated from the output of the seating sensor in the sensor group 201. (Step C24), and when not seated (that is, not driving) (step C24; No), a process based on the operation information included in the received control information is performed. When permitted (step C14) and seated (that is, with a high possibility of driving) (step C24; Yes), it is determined whether processing based on the operation information is permitted or prohibited (step C24). C12).

  Further, as shown in FIG. 15B, step C21 can be skipped.

  Further, as shown in FIG. 16 (a), when it is determined in the process of step C21 that the telephone is in a call state (step C21; Yes), the operation from the output of the mobile terminal position sensor in the sensor group 201 is performed. It is determined whether or not the portable terminal 20 that has transmitted the information is possessed by the driver (at or near the driver's seat) (step C25), and is in a seat other than the driver seat (that is, the driver is When it is not held (step C25; No), processing based on the operation information is permitted, and when it is in the driver seat (that is, held by the driver) (step C25; Yes), it is based on the operation information. It may be determined whether the process (step C14) is permitted or prohibited (step C12). For example, the method described in Patent Document 1 can be used as a method for determining whether or not the driver is carrying the mobile terminal 20 (whether or not the driver seat is in the vicinity of the driver seat). .

  Further, as shown in FIG. 16B, step C21 can be skipped.

4). Fourth Embodiment In the above embodiment, the mobile terminal 20 is the mobile terminal 20 used for keyless entry (unlocking) (step C11; Yes), and the operation corresponding to the operation information is permitted. Although it is an indispensable condition for determining whether or not it is prohibited, it is an additional condition that other conditions are indispensable and the mobile terminal 20 is a mobile terminal 20 used for keyless entry (unlocking). It is also possible to make it a condition.
For example, as shown in FIG. 17, it is determined whether or not the mobile terminal 20 used for unlocking is in a call state (step C21). If the mobile terminal 20 is in a call state (step C21; Yes), the mobile terminal that has transmitted control information. It may be determined whether or not the terminal 20 is a portable terminal used for keyless entry (unlocking) (step C11).

  Further, as shown in FIGS. 18A and 18B, the portable terminal 20 that has transmitted the control information from the output of the portable terminal position sensor in the sensor group 201 is possessed by the driver (in the driver seat). It is determined whether or not it is present (step C25), and when it is in the driver's seat (that is, held by the driver) (step C25; Yes), it is used for whether or not it is in a talking state and / or used for unlocking. It is also possible to determine whether or not the mobile terminal 20 is connected (steps C21 and C11).

  The determination as to whether or not the vehicle is in operation can be similarly changed.

5. Fifth Embodiment In the above embodiment, the mobile terminal 20 is the mobile terminal 20 used for keyless entry (unlocking) (step C11; Yes), and the operation corresponding to the operation information is permitted. However, it is also possible to set a condition for determining whether an operation corresponding to the operation information is permitted or prohibited only under other conditions.
For example, as shown in FIG. 19A, it is determined whether or not the mobile terminal 20 used for unlocking is in a call state (step C21), and if it is in a call state (step C21; Yes), it corresponds to operation information. It may be determined whether the operation to be performed is permitted or prohibited (step C12).

Further, as shown in FIG. 19B, whether or not the portable terminal 20 that has transmitted the other additional conditions (step C26), for example, the control information is possessed by the driver (is in the driver's seat). Or, whether or not the vehicle is in operation may be added.
Further, as shown in FIG. 20, additional conditions may be set for each type of operation and contents.

6). In the embodiment described above, an example in which the in-vehicle device 10 and the mobile terminal 20 perform wireless communication satisfying the BT specification has been shown. However, UWB (Ultra Wide Band), Z-Wave, ZigBee (registered trademark) Communication based on other short-range wireless communication standards such as the above 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.

Further, in the above embodiment, the keyless entry device 30 transfers the terminal ID to the in-vehicle device 10 only when unlocked, but it may be transferred regardless of the result.
In this case, the terminal ID of the BT connection target portable terminal stored in the control memory 12 of the in-vehicle device 10 is not necessarily limited to the keyless entry target, but is arbitrary.

  In the above embodiment, the keyless entry device 30 performs unlocking / locking of the key. However, the keyless entry is not limited to unlocking / locking the key, and the ignition is turned on / off. Also good. 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.

  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, starts the engine, and starts idling. Subsequently, the terminal ID is transferred to the in-vehicle device 10. When the in-vehicle device 10 determines that the terminal ID has already been registered, the in-vehicle device 10 makes a BT connection request to the portable terminal 20 that has instructed the engine start. Similarly, the operation instructed by the mobile terminal 20 to the vehicle may be opening / closing of a window, opening / closing of 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 above embodiment, 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 30. 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 mobile terminal 20 that has performed some operation on the vehicle are arbitrary.

  Further, the terminal ID transmitted by the mobile terminal 20 and the terminal ID stored by the keyless entry device 30 and the in-vehicle device 10 do not have to be the same. The data itself is arbitrary if it can be confirmed that the same portable terminal 20 is designated by a certain process. For example, in the case of an in-vehicle device that needs to be unlocked when activated / used for the purpose of security, the portable terminal used for unlocking may be determined as the portable terminal of the driver. The same applies to the case where the terminal ID of the portable terminal is used for unlocking the in-vehicle device. In addition, when NFC or the like is mounted on both the in-vehicle device and the mobile terminal, there is a system that can be unlocked when it is brought close to a pre-registered mobile terminal. It is also possible to determine that the mobile terminal is owned by the driver.

  Moreover, although the program executed in order to implement | achieve this invention was demonstrated as what was previously memorize | stored in control memory 12,22,32, etc., such an operation program and various data are the vehicle-mounted apparatus 10, portable terminal, and so on. 20. It may be distributed and provided to a computer included in the keyless entry device 30 by a removable recording medium. Furthermore, the operation program and various data may be distributed by downloading from another device connected via a telecommunication network or the like.

  The execution form of each process is not only executed by attaching a removable recording medium, but also temporarily stores the operation program and various data downloaded via a telecommunication network or the like in a built-in storage device. Or may be directly executed using hardware resources on the other device side connected via a telecommunication network or the like. Furthermore, each process may be executed by exchanging various data with other devices via a telecommunication network or the like.

  In addition, this invention is not limited by the above embodiment and drawing. Changes (including deletion of constituent elements) can be added to the embodiments and the drawings as appropriate without departing from the scope of the present invention. For example, you may make it make the portable terminal 20 perform a part of operation | movement in the vehicle-mounted apparatus 10. FIG.
