Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an electronic license plate and the like.

[0002]

2. Description of the Related Art For example, there is known a system such as a car navigation device which realizes various services by connecting a device mounted on a vehicle (vehicle mounted device) to the Internet. When a plurality of vehicle-mounted in-vehicle devices that can be connected to the Internet are installed, each in-vehicle device is uniquely assigned an IP address and communicates with a server or the like connected to the Internet by using this address.

In addition, experimentally, a new application is established by bidirectional communication with an in-vehicle device by experimentally connecting the in-vehicle device to an in-vehicle personal computer, communicating with the outside of the automobile using a mobile phone / DSRC communication, and connecting to the Internet. Are scattered. In such a system, an in-vehicle personal computer and an in-vehicle device are connected via a network, and
The P address is used to enable communication between the server and the like connected to the Internet and the in-vehicle device.

[0004]

However, the IP address assigned to the vehicle-mounted personal computer is preliminarily set in the vehicle-mounted personal computer or is assigned from an external server or the like, so that it has relevance to the vehicle itself. There is no. Therefore, the server or the like that has received the access from the vehicle-mounted device cannot specify which device in the vehicle the access is made by using the IP address of the access source.

Therefore, there is a problem that it is difficult to provide a service for providing information to an in-vehicle device or providing information to an occupant of a vehicle through the in-vehicle device, which reduces the possibility of realizing a new application service. I am letting you. On the other hand, a number written on a license plate is known as information for identifying such a vehicle. And, there is known an electronic license plate that can store vehicle information such as information described in vehicle verification such as number in the license plate and retrieve information stored from the outside by wireless, and will be installed in the vehicle in the future. It is scheduled to be done.

[0006] Therefore, an object of the present invention is to provide an electronic license plate capable of specifying a vehicle and performing communication, and an information system using the electronic license plate.

[0007]

The electronic license plate according to claim 1 made to solve the above-mentioned problems is constructed so that it can be mounted on a vehicle.
The vehicle information is stored, and the vehicle information can be taken out from the outside. When the information is taken out, IP communication is possible,
An IP address for IP communication is assigned. Since the IP address is assigned to the electronic license plate in this manner, for example, the communication partner device or the like uses this IP address.
The vehicle can be specified from the address. Also,
For example, an external device can extract the vehicle information from the electronic license plate and specify the vehicle. Thus, according to the electronic license plate of claim 1,
A vehicle can be specified and communication can be performed.

The electronic license plate according to claim 2 made to solve the above-mentioned problems is a network which is uniquely associated with a vehicle and which is a part of an address used by an in-vehicle device. Remembers the information,
Notify the in-vehicle device of the stored network information. Therefore, an address that can identify the vehicle can be given to the vehicle-mounted device. In this way, the electronic license plate notifies the in-vehicle device of the network information, so that the in-vehicle device can communicate with the outside by using the address including the network information as its own address. Therefore, for example, the device that has received access from the in-vehicle device can specify the vehicle in which the in-vehicle device is mounted from the network information used by the in-vehicle device for access.

The vehicle information may be information including information (for example, a number) that identifies the vehicle. Further, the network information has only to be uniquely associated with the vehicle, and not only the so-called network address but also a predetermined bit portion in the address may be used. The allocation of this part may be determined, for example, according to the protocol used or addressing.

By storing the network information (IP address in claim 1) which is a part of the address in the electronic license plate in this way, the following characteristics can be obtained. Normally, when you buy a vehicle, you always get a license plate. Information related to vehicle verification such as license information is planned to be written in the electronic license plate, and at this time, it is easy to simultaneously write network information in the electronic license plate. Therefore, the information for identifying the vehicle can be stored at an extremely low cost. Note that writing of network information can be realized by configuring as described in claim 3.

Network information can be centrally managed, and issue management can be facilitated. That is, for example, if a vehicle manufacturer allocates network information to an in-vehicle device or the vehicle itself, the network information may be different for each manufacturer and may be duplicated. However, in the case of a license plate, the issuing organization (issuing organization), etc. Can be managed centrally.

It is difficult for the user to remove the electronic license plate once it is installed in the vehicle. Therefore, the relationship between the vehicle itself and the network information cannot be easily changed. Therefore, when the vehicle-mounted device communicates using the network information, the vehicle in which the vehicle-mounted device is mounted can be reliably identified. Further, the vehicle information stored in the electronic license plate can be reliably associated.

When the owner of the vehicle is changed, the vehicle information in the electronic license plate is scheduled to be rewritten, so that the correspondence between the owner information included in the vehicle information and the network information is always kept correct. That is, when the vehicle-mounted device communicates using the address generated from the network information stored in the electronic license plate, the owner can be surely specified from the address. In other words, it becomes possible to obtain vehicle information with a certificate of the issuing agency of the electronic license plate from the address.

As a method of notifying such network information, for example, as described in claim 4, an address including network information is generated by an electronic license plate in response to an address acquisition request from the vehicle-mounted device and notified to the vehicle-mounted device. Good. For example, it may be assigned by a predetermined protocol such as DHCP.

Further, for example, the network information may be notified to the vehicle-mounted device as in claim 5, and the address including the network information may be generated on the vehicle-mounted device side. As such a network information notification method, for example, there is an IPv6 address automatic setting method as set forth in claim 6. That is, in IPv6, the plug-and-play function that the connected device automatically generates an address from the network information can be used. Further, since the address space of IPv6 is larger than that of IPv4, not only information devices such as navigation devices but also various sensors and actuators can be assigned global addresses as in-vehicle devices.

Since the network information uniquely associated with the vehicle can be added to the vehicle-mounted device in this manner, the vehicle or the like can be identified from the address used by the vehicle-mounted device for communication. The network information can be addresses for various communications. For example, it may be a network address of the IP address as shown in claim 7. With this configuration, when the server on the Internet is accessed, the server can identify the vehicle equipped with the in-vehicle device from the network information.

Further, as described in claim 8, the electronic license plate according to any one of claims 2 to 7, and network information is obtained from the electronic license plate, and an address including the network information is provided outside the vehicle. A vehicle information system including an in-vehicle device used for communication with a network can be configured.

As an in-vehicle device of such a vehicle information system, a device for transmitting vehicle position information to a network outside the vehicle can be provided as described in claim 9.
By doing so, for example, the vehicle at a certain position can be specified from the server or the like connected to the network outside the vehicle that has received the position information.

When the vehicle is actually specified from the network information, the side receiving the access from the vehicle-mounted device may store the network information and the vehicle-related information in association with each other. It is also possible to provide a first device in which network information and vehicle-related information are stored in association with each other, and search / extract with the first device. Alternatively, the vehicle-related information corresponding to the network information can be sent to the first device. You may request and receive. The vehicle-related information includes vehicle information such as the vehicle number, vehicle verification information including vehicle information, vehicle specifications, personal information of the vehicle owner as described in claim 15, vehicle position information, and the like. Should be included.

Further, as described in claim 11, the second device which is accessed from the vehicle-mounted device requests the vehicle-related information corresponding to the network information from the first device according to claim 10. It is preferable to generate information to be transmitted to the vehicle-mounted device based on the vehicle-related information. With this configuration, it is not necessary to store the vehicle-related information corresponding to the network information in the second device itself that has been accessed by the vehicle-mounted device, and the second device can perform various applications using the vehicle-related information. Services can be easily provided.

On the contrary, as described in claim 12, the network information corresponding to the vehicle-related information corresponding to the extraction condition may be obtained. Further, as described in claim 13, the second device can transmit the information to the vehicle-mounted device having the address including the network information. By doing so, the second device can transmit appropriate information to the vehicle-mounted device of the vehicle of the user who meets the extraction condition.

Further, as described in claim 14, the first device, which stores the network information and the vehicle-related information in association with each other, receives the distribution condition and the distribution data, and associates with the vehicle-related information corresponding to the received distribution condition. The received distribution data may be transmitted to an address having the obtained network information. With this configuration, the distribution data can be distributed to the vehicle-mounted device of the person who has the specific vehicle-related information. Moreover, since it is not necessary to disclose the relationship between the network information and the vehicle-related information to the sender of the distribution data, it is possible to protect the personal information.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments to which the present invention is applied will be described below with reference to the drawings. Needless to say, the embodiment of the present invention is not limited to the following examples, and various forms can be adopted as long as they are within the technical scope of the present invention.

FIG. 1 shows an electronic license plate 10 of the embodiment.
3 is a block diagram showing the configuration of the communication module of FIG. The electronic license plate 10 is one in which a communication module is incorporated in a license plate on which a vehicle number is written as shown in FIG. The electronic license plate is issued at the time of vehicle registration from the issuing agency together with vehicle verification, and is attached to the vehicle as shown in FIG. 2 (b). Although FIG. 2 (b) shows an example in which it is attached to the front part of the vehicle, it may of course be attached to the rear part of the vehicle.
It may be attached to both rear parts.

As shown in FIG. 1, the communication module comprises an antenna 11, a data transmitter / receiver 12, a communication controller 13, a processor 14, a memory 15, and a network controller 16.
The processing unit 14 has a function of writing information received via the antenna 11, the data transmission / reception unit 12, and the communication control unit 13 into the memory 15.

This writing is performed by the writing device 20 shown in FIG. The writing device 20 uses the vehicle information entered and stored in the database of the host PC 24 and the IPv6 address uniquely determined for each vehicle, or the IPv6 address.
The prefix as the network information, which is a part of the 6 addresses, is transmitted to the communication module via the communication control unit 23, the data transmission / reception unit 22, and the antenna 21. When the communication module of the electronic license plate 10 receives these pieces of information (S110: YES in FIG. 4), the memory 1
The received information is written in 5 (S120).

The vehicle information is information including a vehicle number, vehicle type / vehicle type / model number, vehicle specifications, vehicle owner name, owner address, and the like. The prefix is 12
Of the 8-bit IPv6 address, the upper 64 bits used as a network address are referred to. For example, as shown in FIG. 5, a hexadecimal notation is used to divide the value by 16 bits into colons, and the value is "1997: 0003: fe6".
0: 9713 ". The upper 35 bits in this prefix are values uniquely assigned to the delivering agency, and the lower 29 bits are the host P of the delivering agency.
C24 is a value uniquely assigned in association with each number (that is, vehicle).

Such an electronic license plate 10 is attached to a vehicle, and the network control unit 16 has an in-vehicle server 40a as an in-vehicle device and a PC 4 as shown in FIG.
0b, PDA 40c, navigation device 40d, ET
C vehicle-mounted device 40e, audio 40f, mobile phone 40g,
In-vehicle LAN for connected information systems such as gateway 40h
It is connected to 30 and comprises the information system for vehicles.

The processing unit 14 and the network control unit 16 of the electronic license plate 10 transmit the prefix stored in the memory 15 to the in-vehicle information LAN 30 (router advertisement (RA), the process of S130 of FIG. 4). Equivalent to). Then, each in-vehicle device generates an IPv6 global address with this prefix as the upper 64 bits and the interface ID generated from the MAC address of each in-vehicle device as the lower 64 bits.

Then, it is confirmed by multicast or the like that the generated address is not used by another vehicle-mounted device. If you can confirm the address, use the IP address of your own.
It is set as a v6 global address, and subsequent communication is performed using this set address. Such a mechanism is known as an automatic address setting function (stateless address automatic setting) in IPv6.
In addition to the P address, various settings related to the network can be automatically set.

For example, as shown in FIG. 6, ETC vehicle-mounted device 4
0e is "1997: 0003: fe60: 9713: 0.
It generates its own address such as "000: 0000: 0000: 0001" and confirms that this address is not used elsewhere. When the confirmation is obtained, this address is set as its own address. In this example, other devices similarly search for an address that is not used by another device while incrementing the interface ID, and set the address as its own. Also PC40
For an in-vehicle device that is configured to be detachable from the in-vehicle information LAN 30 such as b, an address can be similarly set by plug and play when connected to the in-vehicle LAN 30 in the information system. With such a configuration, the user can easily use the IP address without setting the IP address or the like.

In this way, each on-vehicle device generates its own address based on the prefix stored in the electronic license plate 10, and communicates using the generated address. Therefore, an external server or the like that has received access from each on-vehicle device can identify the access from the on-vehicle device of the same vehicle by referring to the prefix of the access source address. That is, by accurately associating (associating) the vehicle and the IPv6 address of each vehicle-mounted device, it is confirmed that the access from the vehicle-mounted device in one specific vehicle is surely made. It becomes possible to recognize it from the server.

Therefore, the vehicle to be accessed is specified, the information from each in-vehicle device is integrated and treated as one vehicle information, the session is handed over between each in-vehicle device, and a plurality of in-vehicle devices are connected together. It becomes easy to control. For connection with the Internet, the electronic license plate 10 has an Internet connection function via the communication control unit 13, the data transmission / reception unit 12, and the antenna 11, and also serves as a router, which is an in-vehicle information system L.
The AN 30 may be connected to the external Internet, or an in-vehicle device connected to the in-vehicle information LAN 30 that can communicate with the outside (for example, a mobile phone 40g or a PC 40b) may be connected to the Internet or the like. You may make it connect and exchange information.

Further, the processing unit 14 functions as a server, and uses the vehicle information stored in the memory 15 as the information system in-vehicle LA.
It may be provided to N30 or the Internet.
Further, it is preferable that the prefix stored in the electronic license plate 10 and the vehicle-related information related to the vehicle to which the prefix is added are stored in a server connected to the Internet and can be used via the Internet. .

For example, as shown in FIG. 7, it is possible to configure an information system including an Internet content provider side server 2 and an individual vehicle information center side server 3 each connected to the Internet. The individual vehicle information center side server 3 is installed in the delivering organization and is connected to the host PC 24 of FIG. 3, acquires the prefix held by the host PC 24 and the vehicle verification information including the vehicle information, and further In addition to the acquired information such as age, sex, hobbies, occupation, workplace, work location, and family structure, we are building a personal information database.

On the other hand, on the in-vehicle device side, the navigation device 40d calculates the current position from the GPS and the mobile phone 40g.
Via the Internet to the individual vehicle information center side server 3 connected to the Internet at predetermined time intervals (for example, every 5 minutes)
Send the current position of the vehicle to. The individual vehicle information center side server 3 stores the received current position in the vehicle position management database together with the prefix of the access source. The information stored in the personal information database and the vehicle position management database corresponds to vehicle-related information.

FIG. 8 shows an individual vehicle information center side server 3
Is an example of transmitting the distribution data specified by the Internet content provider side server 2 to the in-vehicle device of the vehicle that meets the distribution condition specified by the Internet content provider side server 2. As shown in FIG. 8, the navigation device 40d, which is an in-vehicle device, acquires the prefix from the electronic license plate 10 as described above, and sets an address including the prefix as its own IP address. Then, the current position is transmitted to the individual vehicle information center side server 3 every predetermined time (corresponding to GPS information in FIG. 8). The individual vehicle information center side server 3
The above-mentioned prefix issue management, personal information management regarding the vehicle owner, and vehicle location information storage management are performed.

Then, the Internet content provider side server 2 transmits the distribution condition and the distribution data to the individual vehicle information center side server 3. This distribution condition specifies the attribute of the other party that the Internet content provider wants to distribute. For example, it is a device installed in the vehicle, a personal information database such as location, age, sex, occupation, etc. or vehicle. This is information managed by the location management database. The distribution data is data that the Internet content provider wants to distribute, and is, for example, an advertisement, a recall guide, a vehicle inspection guide, or the like.

For example, personal information or vehicle verification information is used as a distribution condition such as "I want to distribute this advertisement information to cars in the XX district" or "I want to distribute this guide information to women in their 20s". , Information to be distributed is transmitted as distribution data. The individual vehicle information center side server 3 which has received such distribution conditions and distribution data via the Internet searches the personal information database or the vehicle position management database for a prefix corresponding to the distribution conditions based on the received distribution conditions. , When there is an access from a device having the prefix, the distribution data corresponding to the distribution condition is transmitted. Alternatively, instead of transmitting when the access is made, the address of the device capable of transmitting may be stored in advance in association with the prefix and the distribution data may be push-distributed to the address. Further, when the prefix of the navigation device 40d that transmits the position information is a prefix that meets the distribution condition, the corresponding distribution data may be distributed to the navigation device 40d.

The information distributed in this manner is notified by an in-vehicle device such as the navigation device 40d in the form of images, characters and voice. Therefore, it is possible to send the distribution data that is desired to be sent to the target of the Internet content provider. Moreover, the information can be distributed to the Internet content provider without leaking personal information or the like. Therefore, security of personal information and the like can be ensured. The personal information stored in the individual vehicle information center side server 3 may be input by the user himself from an in-vehicle device or another device connected to the Internet. By doing so, the user himself can control the distribution of information.

Next, an example will be described in which, when the Internet content provider side server 2 receives an access, the Internet content provider side server 2 transmits distribution data suitable for the access source. As shown in FIG. 9, the navigation device 40d, which is an in-vehicle device, acquires a prefix from the electronic license plate 10 and sets an address including the prefix as its own IP address. Then, the current position is transmitted to the individual vehicle information center side server 3 every predetermined time (corresponding to GPS information in FIG. 8). The individual vehicle information center side server 3
It manages issuance of prefixes to vehicles, management of personal information about vehicle owners, and storage management of vehicle location information.

The navigation device 40d transmits a transmission request for the distribution data to the Internet content provider side server 2. Upon receiving this request, the Internet content provider server 2 receives the IP address of the access source.
The address is transmitted to the individual vehicle information center side server 3. The individual vehicle information center side server 3 is the IP
Information corresponding to the prefix of the address is retrieved / extracted from the personal information database or the vehicle position management database and transmitted to the Internet content provider side server 2. The Internet content provider side server 2 receives the search result, selects distribution data matching the search result, and transmits the selected distribution data to the in-vehicle device of the access source. In this way, it is possible to easily change the information to be delivered according to the personal information of the access source or the vehicle verification information.

For example, based on the vehicle verification information, a guide is transmitted to a user of a specific vehicle such as "the vehicle inspection is soon to come", or based on the position information for vehicles in a specific area, It is easy to send time bargain information and pizza delivery information.

In this example, the Internet content provider side server 2 transmits the IP address to the individual vehicle information center side server 3, but only the prefix may be transmitted. Further, the Internet content provider side server 2 may specify necessary information to the individual vehicle information center side server 3. For example, as shown in FIG. 9, the Internet content provider side server 2 transmits a confirmation request of whether it is an in-vehicle device, a position information request or a personal information request together with an IP address,
The individual vehicle information center side server 3 may transmit the search result corresponding to the request.

Alternatively, the Internet content provider side server 2 may specify the extraction condition, and the individual vehicle information center side server 3 may return the prefix corresponding to the extraction condition to the Internet content provider side server 2. Then, the Internet content provider side server 2 may transmit the distribution data in response to access from the address corresponding to this prefix or by push.

Although the network control unit 16 and the processing unit 14 perform the stateless address automatic setting in the above embodiment, the stateful address automatic setting such as DHCPv6 may be performed. That is, you may allocate an address etc. according to the request from a vehicle equipment. Although IPv6 is used in the above embodiment, it can be applied to IPv4 and other protocols.

Further, in the above embodiment, as shown in FIG. 1, each in-vehicle device receives the prefix from the electronic license plate 10 (communication module). However, for example, the in-vehicle server 42 as shown in FIG. You may make it receive via. That is, the function of transmitting the prefix from the electronic license plate 10 to the information system vehicle-mounted LAN 30 is eliminated, and this function is provided.
Provided in 2. That is, the vehicle server 42 reads the prefix stored in the memory 15 of the electronic license plate 10 and transmits the prefix to the information vehicle LAN 30. By doing so, the cost of the electronic license plate 10 can be reduced.

As a vehicle-mounted device, a gateway 40
Various vehicle control devices connected to the control system LAN via h and a power window connected to the body system vehicle-mounted LAN,
Various actuators such as door locks, sensors, etc. can also be used. In the case of IPv6, since the address space is much larger than that of IPv4, it is possible to easily realize various services by assigning addresses to such individual sensors and the like.

In this embodiment, the processing unit 14 and the network control unit 16 correspond to communication means and notification means, and the memory 15 corresponds to storage means. Further, the antenna 11, the data transmission / reception unit 12, the communication control unit 13, the processing unit 1
4 corresponds to a writing means. The individual vehicle information center side server 3 corresponds to the first device, and the Internet content provider side server 2 corresponds to the second device.
