Description

  The present invention relates to an in-vehicle electronic device such as a navigation device to which an on-board device of ETC (Electronic Toll Collection) is detachably connected, and in particular, when the ETC on-vehicle device is newly connected, the ETC on-vehicle device. The vehicle classification information encrypted and registered with the vehicle classification information previously registered in the navigation device by the user is compared by the navigation apparatus, and if the vehicle classification information is not consistent, the fact is notified to the user. The present invention relates to an in-vehicle electronic device that is notified.

  The ETC system consists of an ETC on-board unit into which an ETC card is inserted, a radio antenna device (road equipment) installed in the ETC lane of the toll booth, and ORSE (Advanced Road System Foundation) The information processing apparatus on the network of the propulsion mechanism). When the user passes through the ETC dedicated lane, the gate is opened and closed by performing an authentication process between the ETC on-board unit and the roadside unit. The ORSE information processing apparatus is configured to perform management of charging processing for the ETC card, usage history of the ETC system, and the like.

  According to such an ETC system, it is possible to relieve traffic congestion due to shortened toll collection work at toll booths and to reduce expenses such as labor costs for toll collection. In response to this, the number of users who install ETC in-vehicle devices in vehicles has increased rapidly.

  In recent years, a navigation apparatus has also been proposed in which the ETC on-board unit is electrically connected and various processes are performed using information acquired or generated by the ETC on-board unit. For example, the navigation device disclosed in the following Patent Document 1 (Japanese Patent Application Laid-Open No. 2007-285552) can acquire passing tollgate information stored in the ETC on-board device via the connecting means, and this passing The toll gate can be selectively designated as a destination for route search. Even if specific data is not obtained from the ETC OBE, if the ETC card is still installed in the ETC OBE when the engine is stopped, or if the ETC card is not installed when the engine is started In general, the ETC on-board unit and the navigation device are electrically connected to provide voice notification via the navigation device.

  On the other hand, in the navigation device, if the type of installed vehicle (large car, ordinary car, small car, etc.) is registered and the searched route includes the highway use section, the charge for the highway use section There is also provided a function to which a function for guiding etc. is added.

JP 2007-285552 A

  By the way, when the user purchases the ETC in-vehicle device, an operation called setup is performed. The setup is to store (register) setup information such as the vehicle classification of the vehicle to be installed (classification of toll road charges such as extra large / large / medium / normal / small) and the vehicle number in the ETC on-board unit. . When this setup is performed, the vehicle classification is specified by wireless communication between the toll booth and the ETC on-board device when passing through the ETC dedicated lane, so the user does not have to specify the vehicle classification each time. The usage fee is automatically collected according to the vehicle classification.

  The setup work is performed by a specialized contractor who has received registration authorization. Prior to the work, the setup information is encrypted on the ORSE side. Therefore, the user cannot rewrite the setup information without permission. That is, the ETC vehicle-mounted device in which the vehicle classification information and the number information are registered and the vehicle are always inseparable from each other regardless of whether or not they are attached, and the ETC vehicle-mounted device is replaced with another vehicle. In principle, it cannot be used. If you want to transfer to another vehicle, you will have to do the setup again. Such restrictions are due to ORSE operating rules for the purpose of preventing impersonation.

  However, at the present time, even though the number plate of the vehicle is read when passing through the ETC lane, the ETC on-board device is verified as a correct vehicle by comparing the read number with the number information included in the setup information. It has not been confirmed until it is installed. This is because there are various technical problems at present in order to reliably read the license plate due to differences in the number plate mounting position for each vehicle, dirt on the plate surface, and the like. If license plate verification is performed without these problems being solved, a situation occurs in which the gate is frequently closed due to a number reading error. If this happens, this becomes a factor of traffic jams, which results in conflict with the original purpose of the ETC system (meeting traffic jams).

  From such a current situation, there may be a case where the ETC on-board unit is attached to a vehicle other than the registered vehicle by a user who is not familiar with the ETC usage rules. When such a case occurs, when the vehicle type of the registered vehicle of the ETC in-vehicle device is a normal vehicle, the toll will be different and the route searched by the navigation device will be different. When the toll of the expressway is included in the route guidance and the toll for the tolled section is shown in the route guidance, it will not be consistent with the toll for the large vehicle to be guided, and it will violate the ETC usage rules. .

  As a result of various studies to solve the above problems, the inventor of the present application has found that when an ETC vehicle-mounted device is connected to a vehicle-mounted electronic device such as a navigation device, the vehicle-mounted electronic device such as the navigation device uses the ETC vehicle-mounted device. The vehicle classification registered in the container and the vehicle classification information registered in advance in the vehicle-mounted electronic device such as the navigation device by the user are compared, and if the vehicle classification information is not consistent, the user is notified of the fact. Thus, the user can be alerted, and the present invention has been completed by conceiving that a certain effect is achieved.

  That is, the present invention aims to solve the above problems, and when an ETC on-board device is newly connected to an on-vehicle electronic device such as a navigation device, the vehicle in the setup information registered in the ETC on-board device.

It is a block diagram which shows the structure of the navigation apparatus concerning Example 1 of this invention, and an ETC onboard equipment. It is a flowchart which shows operation | movement of the navigation apparatus concerning Example 1 of this invention. It is a figure which shows the example of a screen on which the vehicle division registered into the ETC onboard equipment was displayed. It is a flowchart which shows operation | movement of the navigation apparatus concerning Example 2 of this invention. It is an external view of the navigation apparatus concerning the Example of this invention provided with the slot for ETC connection.

  Hereinafter, specific examples of the present invention will be described in detail with reference to examples and drawings. However, the embodiment described below exemplifies a navigation apparatus which is an example of a vehicle-mounted electronic device for embodying the technical idea of the present invention. However, the present invention is equally applicable to other in-vehicle electronic devices of other embodiments included in the claims. Hereinafter, the present invention will be described in detail using an example in which a navigation device is used as an in-vehicle electronic device.

  FIG. 1 is a block diagram showing a configuration of a navigation device according to an embodiment of the present invention and an ETC on-vehicle device electrically connected to the navigation device. Of course, the navigation device and the ETC on-vehicle device can be installed and function independently, but they can be connected by a cable and the state of the ETC on-vehicle device can be displayed using the display unit of the navigation device. .

  First, the navigation device 10 will be described. As shown in FIG. 1, the control unit 1 of the navigation device 10 corresponds to information processing means, and includes an internal memory (not shown) such as a CPU, a ROM, and a RAM, and controls the navigation device 10. Further, when the vehicle classification is separately input by the user, the vehicle classification information is registered in the internal memory. This vehicle classification is used when the navigation device 10 performs route search processing in consideration of whether or not a road is allowed to pass by the vehicle classification, or is used for calculating a toll for a highway usage section, It is arbitrarily registered according to the vehicle installed by the user. Therefore, there is a user who does not register information even if there is a vehicle segment registration function. On the other hand, the vehicle classification information registered in advance in the ETC vehicle-mounted device 20 is set up according to the usage rules required by the management organization as described above, and is different in character from the registration of the vehicle classification in the navigation device.

  The operation unit 2 includes various keys and switches for inputting a destination in the navigation device 10 and other various inputs. The vehicle classification is also input to the navigation device 10 through the operation unit 2.

  The display unit 3 plays a role as a man-machine interface for displaying a map image, an optimal route image, and a guidance guide image so that the user can visually recognize the image, and is configured by a liquid crystal display, for example. In addition, this display part 3 can also be comprised so that it may comprise a touch sensor and may bear a part of operation part 2. FIG. In this case, selection input is performed when the user touches an icon displayed on the screen.

  The current position detection unit 4 detects the current position of the vehicle using a GPS signal, a speed sensor, an azimuth sensor, or the like.

  The map storage unit 5 stores map data including road node data whose nodes are nodes such as road intersections and branch points, and road link data whose links are links between the nodes. More specifically, the road (route) of the map data is the node, the position of the inflection point is the road node, the route connecting each road node is the link, and the cost information (distance and required time) of all the links is the database. I have.

  The route search unit 6 searches for an optimum route from the current position detected by the current position detection unit 4 to the destination designated via the operation unit 2. More specifically, the road network data stored in the map storage unit 5 is referred to sequentially search for a link from the starting node to the destination node, and the node and link with the minimum cost information To determine the optimum route. Note that, as such a route search method, a method called label determination method or Dijkstra method is used.

  The route storage unit 7 stores the optimum route searched by the route search unit 6 as described above.

  At the time of route guidance, the control unit 1 displays map data in a predetermined range centered on the current position detected by the current position detection unit 4 among the optimum route data stored in the route storage unit 7 on the display unit 3. In addition to displaying, when reaching the guidance notification point stored in the data of the optimum route, guidance notification is performed via the voice output unit 8 described later. In this way, guidance to the destination is performed while switching the display of the map data each time according to the current position that changes every moment.

  The voice output unit 8 is configured by a speaker or the like, and performs guidance notification at the time of guidance guidance via the optimum route, key operation sound, and other various types of voice notification related to the navigation device 10. Further, when the ETC card is still attached to the ETC vehicle-mounted device 20 when the engine is stopped, or when the ETC card is not attached when the engine is started, it is also used for voice notification to that effect.

  The vehicle classification specifying unit 9 is configured as a one-chip IC, and stores a decoding program for functioning as a decoder. More specifically, the encrypted setup information stored in the ETC on-vehicle device 20 is decrypted, and only the vehicle classification information contained therein is output to the control unit 1. Since the setup information is subjected to highly confidential high-level encryption processing, it is assumed that the decryption program is provided to the manufacturer of the navigation device. However, this is not the case in the second embodiment to be described later because a decoding decoder is not required.

  Next, the ETC vehicle-mounted device 20 will be described. The ETC vehicle-mounted device 20 includes an ETC card reader 21, a transmission / reception unit 22, a vehicle-mounted device identification information storage unit 23, and a setup information storage unit 24.

  The ETC card reader 21 detects whether or not an ETC card is mounted, and accepts the ETC card and reads ID information of the ETC card.

  The transmission / reception unit 22 has a wireless antenna function, and when the vehicle passes through the entrance or exit of the toll road, transmits the card ID information, the identification information of the ETC on-board device 20 and the like to the road unit installed at the entrance and exit. In addition, it is responsible for receiving tollgate data and the like that has passed from the roadside machine.

  The in-vehicle device identification information storage unit 23 stores in-vehicle device identification information unique to the ETC on-vehicle device 20. As described above, the vehicle-mounted device identification information is used when wirelessly communicating with the roadside device at the toll gate. In the modification described below, the vehicle-mounted device identification information is used when the navigation device 10 specifies the vehicle classification. It is also used when the ETC on-board device 20 is specified using the information and the setup information of the corresponding ETC on-board device is acquired from the outside (other than the ETC on-board device 20).

  The setup information storage unit 24 stores setup information. The setup information is encrypted on the ORSE side and includes vehicle number information associated with the ETC vehicle-mounted device 20 and vehicle classification information.

  Next, the operation of the navigation device 10 of the present invention will be described with reference to the flowchart of FIG. First, it is assumed that the navigation device 10 is in a standby state with the power on (step S1 (NO), step S2 (NO)). In this state, when the ETC on-vehicle device 20 is connected to the navigation device 10 with a cable or the like (step S1 (YES)), the control unit 1 stores the encrypted setup information from the setup information storage unit 24 of the ETC on-vehicle device 20. Read-out and transfer the setup information to the vehicle classification specifying unit 9 (step S3).

  Next, the vehicle classification specifying unit 9 functioning as a decoder decodes the received setup information, extracts the vehicle classification information from the decoded setup information, and transfers the vehicle classification information to the control unit 1 (step S4). The control unit 1 that has received the vehicle classification information reads the vehicle classification information stored in advance in the internal memory of the control unit 1 and registers it in the vehicle classification information received from the vehicle classification specifying unit 9, that is, the ETC on-board device 20. The vehicle classification information is compared (step S5), and it is determined whether or not the vehicle classifications match (step S6).

  Here, when it is determined that the vehicle classifications match (step S6 (YES)), the process proceeds to step S2. On the other hand, when it is determined that the vehicle sections are different (step S6 (NO)), the display unit 3 is controlled to notify the user of a warning that the vehicle sections do not match (step 7).

  FIG. 3 shows a screen example of the liquid crystal display displayed at this time. On the screen, “medium-sized vehicle” is displayed large in the center, and the user is notified that the registered vehicle classification of the ETC vehicle-mounted device 20 connected to the navigation device 10 is “medium-sized”. At the same time, the vehicle category registered by the user in the navigation device 10 is “large”, the toll road usage fee varies depending on the vehicle category, and the ETC in-vehicle device 20 is only a vehicle registered at the time of setup. The fact that it cannot be used is notified through a text display on the screen.

  As described above, according to the navigation device 10 of the present embodiment, when the ETC vehicle-mounted device 20 is newly connected to the navigation device 10, the vehicle classification information registered in advance by the user and the ETC vehicle-mounted device 20 are registered. Comparison with the vehicle classification information is performed, and when these vehicle classifications do not match, the fact is notified to the user through the monitor screen of the navigation device 10 or a speaker. Thereby, it becomes possible to prompt the user to confirm the matching between the vehicle classification of the vehicle to be used and the vehicle classification registered in the ETC on-board unit 20. Thereby, when it mounts in the vehicle different from the vehicle classification registered into the ETC onboard equipment 20, it becomes possible to call attention, such as causing a problem in the calculation of the highway toll.

  In the embodiment described above, the encrypted setup information acquired from the setup information storage unit 24 of the ETC on-vehicle device 20 is decrypted in the vehicle classification specifying unit 9, and only the vehicle classification information contained therein is controlled by the control unit 1. Although the structure provided with the decoder which outputs to is demonstrated, it can also be set as the structure which acquires from the database which accumulate | stored the vehicle division information decoded beforehand.

  The database as described above will be made possible by ETC's private open operation (see http://www.orse.or.jp) that started in 2004. This private operation is based on the setup information (encrypted setup information) of the ETC OBE of the user who wishes to pay for ETC in the parking lot by contracting with ORSE by various operators such as parking lot management operators. ), And the user ETC information can be compiled into a database. The navigation device manufacturer constructs such a database, and the ETC in-vehicle connected to the navigation device from this database. Vehicle setup information can be obtained to identify vehicle classification.

  That is, a private business operator (for example, a parking lot business operator) who wants to use ETC for toll collection applies for service subscription (user name, identification information of ETC on-board device to be used) from each user who wants to use the service. And requests the ORSE to provide setup information. The ORSE provides the setup information of the applied ETC in-vehicle device to the operator. At this time, the setup information provided to the provider is provided in an encrypted form from the viewpoint of unauthorized use and protection of personal information, and the provider constructs an ETC database for providing services by decrypting the setup information. Therefore, if each ETC on-board device is specified by the identification information of the ETC on-board device, it is possible to obtain the decoded setup information of the corresponding ETC on-board device from the ETC database constructed by the operator.

  In the case of the second embodiment, the setup information is acquired from an external database without being directly acquired from the ETC on-board device 20, and therefore, the setup information storage unit 24 (FIG. 1) provided in the normal ETC on-vehicle device 20. Is not necessarily required.

  Various methods can be adopted as a method of acquiring the vehicle classification information from the database. For example, setup information corresponding to the ETC in-vehicle device 20 connected to the navigation device 10 is acquired from a database constructed by a manufacturer of the navigation device using a communication function (not shown) provided in the navigation device 10. It can be constituted as follows.

  If the user of the navigation device 10 knows the ETC vehicle-mounted device 20 to be mounted in advance, the setup information is taken into the vehicle classification specifying unit 9 from the database together with the identification information of the corresponding ETC vehicle-mounted device 20 offline. It can also be left. In this case, when the ETC vehicle-mounted device 20 is connected to the navigation device 10, the identification information stored in the ETC vehicle classification specifying unit 9 may be checked to display the vehicle classification information.

  Alternatively, the vehicle classification specifying unit 9 may be provided with a vehicle classification data table in which identification information and setup information of all ETC on-board devices acquired by the manufacturer of the navigation device are stored in association with each other.

  Next, the operation of the navigation device according to the second embodiment of the present invention will be described with reference to the flowchart of FIG. The procedure shown in the flowchart of FIG. 4 has a configuration including a vehicle classification data table in which identification information and setup information of all ETC on-board devices acquired by the operator are associated with and stored in the vehicle classification specifying unit 9. It is a procedure based on.

  First, it is assumed that the navigation device 10 is in a standby state with the power on (step S8 (NO), step S9 (NO)). In this state, when the ETC on-vehicle device 20 is connected to the navigation device 10 with a cable or the like (step S8 (YES)), the control unit 1 obtains the on-vehicle device identification information from the on-vehicle device identification information storage unit 23 of the ETC on-vehicle device 20. It reads out and delivers vehicle equipment identification information to the vehicle classification specific part 9 (step S10).

  Next, the vehicle classification specifying unit 9 specifies the vehicle classification information associated with the onboard equipment identification information with reference to the received onboard equipment identification information and the data table, and sends the vehicle classification information to the control section 1. Deliver (step S11). The control unit 1 that has received the vehicle classification information reads the vehicle classification information stored in advance in the internal memory of the control unit 1 and registers it in the vehicle classification information received from the vehicle classification specifying unit 9, that is, the ETC on-board device 20. The vehicle classification information thus compared is compared (step S12), and it is determined whether or not these vehicle classifications match (step S13).

  If it is determined that the vehicle classifications match (step S13 (YES)), the process proceeds to step S2. On the other hand, when it is determined that the vehicle sections are different, the display unit 3 is controlled to notify the user of a warning that the vehicle sections do not match (step 14). Also by this modification, the same effect as the navigation apparatus 10 according to the first embodiment described above can be obtained.

  Next, a schematic structure of the navigation device 10 according to the first and second embodiments will be described.

  FIG. 5 is an external view of the navigation apparatus 10 according to the embodiment of the present invention in which an ETC connection slot is provided. In the navigation device 10, the liquid crystal display 11 and the operation button group 12 are configured to be pulled out from the navigation device main body 100, and a CD / DVD insertion slot 13 and a CD are provided on the front surface of the main body 100 of the navigation device 10. In addition to the / DVD eject button 14 and the SD card insertion slot 15, a connection slot 16 for connecting a separately purchased ETC on-vehicle device 20 to the navigation device 10 is provided.

  When connecting the ETC vehicle-mounted device 20 to the navigation device 10, a connection connector (not shown) led out from the connection slot 16 was pulled out and a connection connector (not shown) on the ETC vehicle-mounted device 20 side was connected. Thereafter, the ETC vehicle-mounted device 20 is fitted into the connection slot 16 and attached, and the connection between the navigation device 10 and the ETC vehicle-mounted device 20 is completed. In the figure, a state in which the ETC vehicle-mounted device 20 is already connected is shown.

  As described above, if the ETC in-vehicle device 20 can be attached to and detached from the navigation device 10, even if the manufacturer of the navigation device 10 and the manufacturer of the ETC on-vehicle device 20 are different, the user can use the navigation device. 10 and ETC on-vehicle device 20 can be purchased, the ETC on-vehicle device 20 can be attached to the navigation device 10 by a car goods sales company.

  If the navigation device 10 is provided with the connection slot 16 in which the ETC in-vehicle device can be attached and detached, first, first, when the navigation device 10 and the ETC in-vehicle device 20 are integrally incorporated, for example, If the navigation device 10 breaks down, ETC registration (setup) must be performed again. However, if the navigation device 10 is detachable, the ETC in-vehicle device 20 can be replaced with another navigation device 10 even if the navigation device 10 breaks down. There is no need for re-setup. If the ETC in-vehicle device 20 breaks down, it can be removed and repaired. Secondly, a dedicated wiring for connecting the ETC in-vehicle device 20 to the navigation device 10 is not necessary, and the appearance is clean. Thirdly, the wiring work is not necessary even as a car goods store. Fourth, even when the user retrofits the ETC in-vehicle device 20 to the navigation device 10, there is an advantage that wiring work and cost are not necessary.

  In addition, in the said Example, the setup information stored in ETC onboard equipment demonstrated as what was encrypted. This is due to the ORSE operating rules in consideration of security. However, it goes without saying that if the setup information is stored in the ETC vehicle-mounted device without being encrypted, the registered vehicle classification information can be acquired without being decrypted.
