JP 2012-164258 A

  By the way, in recent years, in the road-to-vehicle communication system as described above, at the time of road-to-vehicle communication, an information center that supervises the roadside machine by uplinking, for example, traveling history information of the own vehicle as a data log from the vehicle-mounted device to the roadside machine. A service has been proposed in which such uplink information is collected and used for driving support through statistical processing. However, from the viewpoint of protecting personal information, some users may not want to be uplinked. Therefore, when the user operates the smart phone to set permission / prohibition of uplink, the vehicle-mounted device operates based on the setting.

  However, for example, even if the smartphone owned by the driver has been set to prohibit the uplink, the smartphone owned by a passenger, such as a family member, will then uplink when connecting to the vehicle-mounted device. However, there is a problem that an uplink is made against the driver's intention, leaving room for improvement.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to allow data logs to be uplinked to a roadside device, and to permit uplink without the vehicle user's intention. / To provide a vehicle-mounted device that can prevent the setting of prohibition from being changed.

  In order to achieve the above object, the vehicle-mounted device of the present invention is capable of uplinking a data log to a roadside device, and is connected to a portable terminal owned by a user who rides on the vehicle. And setting means for setting permission / prohibition of uplink based on uplink setting information notified from the mobile terminal in a connection state with the mobile terminal, and connection when the mobile terminal is connected. Determining means for determining whether or not the mobile terminal that has been connected matches the mobile terminal connected to the previous time, and when it is determined by the determining means that a mobile terminal different from the previous time is connected, the user is notified of this fact. And a notification means (invention of claim 1).

  According to this, uplink setting information is notified from the portable terminal in a state where the connection means is connected to the portable terminal owned by the user, and uplink permission / prohibition by the setting means based on the uplink setting information. Is set. Thereby, for example, when the usual portable terminal possessed by the driver is connected, the setting as intended by the user (driver) is made the same every time unless the setting is changed on the portable terminal side.

  On the other hand, for example, when there is an occupant different from the usual user and different (multiple) mobile terminals are connected, the uplink permission / prohibition setting is the same as the previous (first) connected mobile terminal. There is a risk of a difference. However, in this case, when the mobile terminal is connected, the determination unit determines whether the connected mobile terminal matches the mobile terminal connected last time, and determines that a mobile terminal different from the previous one is connected. When this happens, the notification means notifies the user to that effect.

  Therefore, the user of the vehicle can know that there is a possibility that the uplink permission / prohibition setting is changed by the notification from the notification means, and can take appropriate measures. As a result, it is possible to prevent the uplink permission / prohibition setting from being changed without the intention of the vehicle user.

At this time, the smartphone 5 can be connected to the DSRC in-vehicle device 3 by installing the cooperative application. When the cooperation application of the smart phone 5 is executed in the vehicle 2, it is automatically connected to the DSRC in-vehicle device 3 and operates in cooperation. Thereby, the road traffic information acquired by the DSRC on-vehicle device 3 can be displayed on the display unit 22 of the smartphone 5, or various settings of the DSRC on-vehicle device 3 can be performed by the operation of the smartphone 5. The

  As described above, a plurality of smartphones 5 (two are shown in FIG. 2) can be connected to the DSRC in-vehicle device 3. However, the connection operation with the smartphone 5 is sequentially performed for each device. Moreover, when the smart phone 5 (user with the smart phone 5) leaves | separates from the vehicle 2 (DSRC onboard equipment 3), a connection will be cut off automatically. That is, the connection between the DSRC in-vehicle device 3 and the smartphone 5 is temporarily performed when the smartphone 5 is brought into the vehicle 2.

  As will be described later in the description of the operation, in the road-to-vehicle communication system 1 according to this embodiment, the DSRC on-vehicle device 3 transmits the ITS spot during the road-to-vehicle communication between the DSRC on-vehicle device 3 and the ITS spot roadside device 4. For example, traveling history information of the vehicle 2 can be uplinked to the roadside machine 4 as a data log. In this case, a service is realized in which the uplink information is collected at an information center that supervises the ITS spot roadside device 4 and statistically utilized for driving support and the like.

  However, from the viewpoint of personal information protection, some users may not want to uplink their travel history information of the vehicle 2. Therefore, the user can input permission / prohibition of uplink by operating the input operation unit 24 of the smartphone 5. The smartphone 5 (the control unit 21) notifies its own ID information and the uplink setting information (permission / prohibition information) when connected to the DSRC on-vehicle device 3. The control unit 11 of the DSRC on-vehicle device 3 writes the uplink setting information notified at the time of connection with the smartphone 5 to the storage unit 15 and controls the operation of the uplink based on the uplink setting information. Therefore, the control unit 11 functions as a setting unit.

  As will be described in the following description of the operation, in the present embodiment, when the smartphone 5 is connected, the control unit 11 of the DSRC on-vehicle device 3 is connected to the smartphone 5 to which the connected smartphone 5 was connected last time (latest). Determine whether they match. And when it determines with the smart phone 5 different from the last time having been connected, the control part 11 notifies that to a user. Therefore, the control unit 11 functions as a determination unit and a notification unit.

  Specifically, in the present embodiment, the determination of the match of the smartphone 5 stores the ID information of the smartphone 5 connected last time in the storage unit 15 and stores the ID information of the smartphone 5 connected this time. Based on the comparison with the ID information stored in the unit 15, it is determined whether or not they match. Further, in the present embodiment, notification that the smartphone 5 different from the previous one is connected is performed by notifying means of the DSRC in-vehicle device 3, that is, by screen display and audio output of the display unit 16 and the audio output unit 13. It has become. More specifically, in this notification, the user is notified by display or voice of whether the uplink setting information by the smartphone 5 connected this time is set to permitted or prohibited.

  Next, the operation of the above configuration will be described with reference to FIG. When the user who owns the smartphone 5 gets into the vehicle 2 and the cooperation application is installed in the smartphone 5, the user operates the smartphone 5 to instruct the execution of the cooperation application, so that the smartphone 5 and the DSRC in-vehicle device 3 are automatically connected (Bluetooth wireless connection), and a coordinated operation is executed. When the vehicle 2 is traveling on the highway H, the DSRC on-vehicle device 3 performs road-to-vehicle communication (DSRC narrow-area wireless communication) with the ITS spot roadside device 4 to acquire road traffic information. And toll settlement processing on toll roads.

  At the same time, when the DSRC on-vehicle device 3 has permission set based on uplink setting information (uplink permission / prohibition information) set in advance during road-to-vehicle communication with the ITS spot roadside device 4. For example, the traveling history information of the vehicle 2 is uplinked to the ITS spot roadside device 4 as a data log. At this time, the uplink setting information is notified together with the ID information from the smartphone 5 and stored in the storage unit 15 when the DSRC in-vehicle device 3 and the smartphone 5 are connected.

  In this case, the user can set permission / prohibition of uplink on the initial setting screen when the cooperative application is first executed on the smartphone 5, for example. Of course, the user may set the permission to allow the uplink, and set the prohibition if the user does not want to uplink his / her vehicle travel history information. Thereby, for example, when the usual smartphone 5 (A) possessed by the driver is connected, unless the setting is changed on the smartphone 5 (A) side, the uplink of the user (driver) as intended The settings are made the same every time.

  Here, as described above, a plurality of smartphones 5 can be connected to the DSRC in-vehicle device 3. For example, both the driver and the passenger carry the smartphones 5 (A) and 5 (B). Suppose that Now, for example, in the smartphone 5 (A) possessed by the driver connected to the DSRC in-vehicle device 3, passengers such as the driver's family, even though the uplink prohibition is set. There is a case in which the smartphone 5 (B) possessed by is configured to allow uplink when connected to the DSRC on-vehicle device 3 thereafter.

  At this time, contrary to the intention of the driver, there is a possibility that the uplink is set by the connection of the smartphone 5 (B) and the uplink is made. That is, for example, when there is an occupant who is different from the usual user and a different smartphone (several) 5 (B) is connected, the uplink permission / prohibition setting is set to the smartphone 5 connected last time. There is a possibility of being different from (A).

  However, the DSRC in-vehicle device 3 (control unit 11) of the present embodiment executes the processing shown in the sequence diagram of FIG. 3 when connected to the smartphone 5, thereby preventing the above problems. That is, FIG. 3 shows a main part of the procedure of the process executed when the DSRC on-vehicle device 3 (control unit 11) is connected to the smartphone 5 and the communication (notification from the smartphone 5).

  First, in step S1, a connection process between the DSRC on-vehicle device 3 and the smartphone 5 is executed. When the connection is made, the uplink setting information (permission / prohibition) is notified from the smartphone 5 to the DSRC in-vehicle device 3 in the notification C1. Then, in the DSRC in-vehicle device 3, in step S <b> 2, uplic permission / prohibition is set based on the notified uplink setting information. In the next notification C <b> 2, ID information is notified from the smartphone 5 to the DSRC in-vehicle device 3.

  When the ID information is notified from the smartphone 5, the DSRC in-vehicle device 3 compares the ID information of the smartphone 5 at the previous connection with the ID information notified this time in step S3. If it is determined that the ID information of the smartphone 5 connected this time is different from the ID information of the smartphone 5 at the previous connection, the uplink is set to either permitted or prohibited in step S4. The display unit 16 or the audio output unit 13 of the DSRC in-vehicle device 3 is notified of whether or not it has been done. This notification is, for example, “set to allow uplink” or “set to prohibit uplink”. If the ID information of the smartphone 5 at the previous connection matches the current ID information, the applicability setting / prohibition setting is validated as it is, and the subsequent operation is executed.

  Thus, the user (the driver of the vehicle 2) knows that the uplink permission / prohibition setting has been changed by the connection of the smartphone 5 by the notification of whether the uplink permission / prohibition has been set. Can do. In this case, if the user accepts the uplink setting that has been notified, nothing needs to be done. If the user does not want to set a new uplink, for example, by operating the smartphone 5, the uplink is performed. Appropriate measures can be taken, such as changing permission / prohibition settings.

  As described above, according to the DSRC in-vehicle device 3 of the present embodiment, the data log can be uplinked by road-to-vehicle communication with the ITS spot roadside device 4 and connected to the smartphone 5. When it is determined that a smartphone 5 different from the previous one is connected in the state where uplink permission / prohibition is set in the state, the user of the vehicle 2 may change the uplink permission / prohibition setting by notification. Know that there is, and take appropriate action. As a result, it is possible to prevent the uplink permission / prohibition setting from being changed without the intention of the user of the vehicle 2.

  In particular, in the present embodiment, since the DSRC in-vehicle device 3 and the smartphone 5 as a mobile terminal are configured to be wirelessly connected by the Bluetooth method, the connection with the smartphone 5 can be easily and reliably performed. In addition, since the display unit 16 or the audio output unit 13 of the DSRC in-vehicle device 3 is used as a means for notifying the user that the uplink permission / prohibition setting may be changed. In addition, it is possible to reliably notify the occupant of the vehicle 2, particularly the driver. Furthermore, in this embodiment, since the ID information of the smartphone 5 is used to determine whether or not the connected smartphone 5 matches the previously connected one, the determination can be performed easily and reliably. Etc. can also be obtained.

(2) Second to fourth embodiments and other embodiments FIGS. 4, 5, and 6 show the second, third, and fourth embodiments of the present invention, respectively. In the fourth embodiment, the process executed by the DSRC in-vehicle device 3 (control unit 11) when connected to the smartphone 5 is different from that of the first embodiment. Accordingly, in the second to fourth embodiments, the road-to-vehicle communication system 1 and the hardware configuration of the DSRC in-vehicle device 3 are the same as those in the first embodiment.

  The sequence diagram of FIG. 4 is the main part of the procedure executed by the DSRC in-vehicle device 3 (control unit 11) when connected to the smartphone 5 and the communication (notification from the smartphone 5) in the second embodiment. Is shown. In the second embodiment, when it is determined that the smartphone 5 different from the previous one is connected, the control unit 11 has changed the setting contents of the uplink permission / prohibition in the notified uplink setting information. It is configured to notify the user on the condition.

  That is, first, in step S1, a connection process between the DSRC on-vehicle device 3 and the smartphone 5 is executed. When the connection is made, the uplink setting information (permission / prohibition) is notified from the smartphone 5 to the DSRC in-vehicle device 3 in the notification C1. Then, in step S11, the DSRC in-vehicle device 3 determines whether or not the appric is permitted / prohibited based on the notified uplink setting information and whether or not the setting has been changed from the previous time. Remembered. In the next notification C <b> 2, ID information is notified from the smartphone 5 to the DSRC in-vehicle device 3.

  When the ID information is notified from the smartphone 5, the DSRC in-vehicle device 3 compares the ID information of the smartphone 5 at the previous connection with the ID information notified this time in step S3. If it is determined that the ID information of the smartphone 5 connected this time is different from the ID information of the smartphone 5 at the previous connection, it is determined in step S11 that the setting has been changed from the previous time. On the condition that this is done, in step S4, the display unit 16 or the voice output unit 13 of the DSRC on-vehicle device 3 is notified of whether the uplink is set to be permitted or prohibited. Thereby, the user (the driver of the vehicle 2) knows that the setting of the uplink permission / prohibition has been changed by the connection of the smartphone 5 this time by the notification of the setting change of the uplink permission / prohibition in step S4. be able to.

  Therefore, also in the second embodiment, as in the first embodiment, the data log can be uplinked to the ITS spot roadside device 5, and the user of the vehicle 2 intends to Thus, it is possible to prevent the uplink permission / prohibition setting from being changed. In this case, since it is a problem that the setting contents of permission / prohibition of uplink change, it is possible to avoid unnecessary notifications by performing notification only when there is a change. it can.

  The sequence diagram of FIG. 5 shows a third embodiment. In this third embodiment, when it is determined that a smartphone 5 different from the previous one is connected, the control unit 11 is configured to respond to the user when the vehicle 3 passes through an ETC gate provided at the entrance of the highway H. It is configured for notification.

  That is, first, in step S1, a connection process between the DSRC on-vehicle device 3 and the smartphone 5 is executed. When the connection is made, the uplink setting information (permission / prohibition) is notified from the smartphone 5 to the DSRC in-vehicle device 3 in the notification C1. Then, in the DSRC in-vehicle device 3, in step S <b> 2, uplic permission / prohibition is set based on the notified uplink setting information. In the next notification C <b> 2, ID information is notified from the smartphone 5 to the DSRC in-vehicle device 3.

  When the ID information is notified from the smartphone 5, the DSRC in-vehicle device 3 compares the ID information of the smartphone 5 at the previous connection with the ID information notified this time in step S3. And when it determines with the ID information of the smart phone 5 connected this time differing from the ID information of the smart phone 5 at the time of last connection, whether the vehicle 2 passed the ETC gate in the following step S21. Judgment is made. When it is determined that the ETC gate has been passed, in step S4, whether the uplink is set as permitted / prohibited is indicated to the user by the display unit 16 or the voice output unit 13 of the DSRC in-vehicle device 3. Be notified.

  According to the third embodiment, similar to the first embodiment, the data log can be uplinked to the ITS spot roadside device 5, and the user of the vehicle 2 intends. It is possible to prevent the uplink permission / prohibition setting from being changed. And it is on the highway H that the uplink is executed with respect to the ITS spot roadside machine 4, and there is no problem with the uplink on the general road, so the vehicle 2 passes through the ETC gate and the highway. By notifying when entering H, unnecessary notification can be avoided.

  The sequence diagram of FIG. 6 shows the fourth embodiment. In this 4th Example, when it determines with the smart phone 5 different from the last time having been connected, the control part 11 notifies that to a user, and is the setting of an uplink. The contents are automatically set to prohibited. Therefore, in the fourth embodiment, the control unit 11 has a function as a prohibiting unit.

  That is, first, in step S1, a connection process between the DSRC on-vehicle device 3 and the smartphone 5 is executed. When the connection is made, the uplink setting information (permission / prohibition) is notified from the smartphone 5 to the DSRC in-vehicle device 3 in the notification C1. Then, in the DSRC in-vehicle device 3, in step S <b> 2, uplic permission / prohibition is set based on the notified uplink setting information. In the next notification C <b> 2, ID information is notified from the smartphone 5 to the DSRC in-vehicle device 3.

  When the ID information is notified from the smartphone 5, the DSRC in-vehicle device 3 compares the ID information of the smartphone 5 at the previous connection with the ID information notified this time in step S3. And when it determines with the ID information of the smart phone 5 connected this time differing from the ID information of the smart phone 5 at the time of last connection, in the next step S31, the smart phone 5 different from the last time was connected. This is notified to the user, and the prohibition of uplink is set regardless of the uplink setting information.

  Accordingly, in the fourth embodiment, as in the first embodiment, the data log can be uplinked to the ITS spot roadside device 5, and the user of the vehicle 2 intends. It is possible to prevent the uplink permission / prohibition setting from being changed. And when it determines with the smart phone 5 different from the last time having been connected, since the setting content of an uplink is set to prohibition, it will be set to the safe side, in other words, a vehicle without a user's intention. It is possible to prevent the traveling history information from being uplinked.

  In addition, in this 4th Example, when it determined with the smart phone 5 different from the last time having been connected, it comprised so that the setting content of an uplink might be automatically prohibited, However, The portable terminal different from the last time When it is determined that is connected, initialization means for returning the uplink setting contents to the initial state (the initial setting state by the user) may be provided. Also with this configuration, it is possible to prevent an uplink permission / prohibition setting from being arbitrarily changed in a direction not desired by the user.

  In addition, the present invention is not limited to the above-described embodiments, and can be expanded and changed as follows, for example. That is, in each of the above-described embodiments, the smartphone 5 is a specific example of the mobile terminal possessed by the user.
