JP 2007-112436 A JP 2007-290594 A

  Normally, the reading of the license data is locked, and in order to read the information from the license, it is necessary to input a personal identification number or the like. However, since it is troublesome for the user to input the personal identification number, there is a need to simply read data while maintaining security against data reading.

  An object of the present invention is to provide a license information access system capable of simplifying an operation for reading out license information from a license.

  The license information access system that solves the above-mentioned problem is a configuration used when the vehicle acquires the license information directly or indirectly from the license, and the authentication information that can be freely read from the license An information acquisition unit that is acquired from a license, all or part of the password data that is required when extracting the license information from the license, and the authentication information that is associated with the password data are stored together. A data acquisition unit for acquiring the password data associated with the authentication information based on the authentication information acquired from the license, and accessing the license information of the license based on the password data And an information access unit.

  According to this configuration, the authentication information and the password data (authentication data is all or part) registered in the license are stored in a predetermined storage area of the electronic key. When the vehicle accesses the license information of the license, the authentication information is obtained from the license, the password data associated with the authentication information is taken from the electronic key, and the license is accessed based on the password data, Extract license information from the license. For this reason, when acquiring license information from a license, there is no need to impose a task of inputting password data to the user. Therefore, it is possible to simplify the operation for reading out the license information from the license.

  In the license information access system, it is preferable that the authentication information and the password data are stored together in a secure element of the electronic key. According to this configuration, since the authentication information and the password data are written in the secure element of the electronic key, it is possible to ensure security against unauthorized reading.

  In the license information access system, it is preferable that the authentication information is an expiration date of the license. According to this configuration, since the expiration date can be read out without the password data in the license information, the license information can be easily retrieved using the expiration date registered in the license. It becomes possible.

  In the license information access system, the data acquisition unit is configured to store the password stored in the secure element of the electronic key on the condition that ID verification according to the electronic key system is established between the vehicle and the electronic key. It is preferable to provide data to the vehicle. According to this configuration, when the vehicle captures the password data from the electronic key, the establishment of ID verification between the vehicle and the electronic key is imposed. Therefore, security can be ensured when the password data is extracted from the electronic key. It becomes possible.

  In the license information access system, it is preferable that near field communication is used for communication between the vehicle and the license. According to this configuration, since the communication between the vehicle and the license is executed when the license is consciously brought close to the antenna, there is a situation where the communication is performed without the intention of the user. It becomes difficult to occur.

  According to the present invention, the operation for reading out the license information from the license can be simplified.

Next, the operation of the license information access system 20 will be described with reference to FIGS.
[Registration of authentication information and PIN data in the electronic key]
As shown in FIG. 2, in step 101, the electronic key 2 and the verification ECU 4 complete a smart verification between the vehicle 1 and the electronic key 2 in advance when registering the expiration date and password in the electronic key 2. Note that the pairing confirmation of the vehicle 1 and the electronic key 2 is not limited to confirmation of whether or not the smart collation is established, but may be changed to another method capable of confirming that the regular electronic key 2 exists at hand. Is possible.

  In step 102, the registration execution unit 28 of the license ECU 21 inputs a user registration request for starting an operation for storing the expiration date and the password in the electronic key 2. The user registration request is input by operating a dedicated button for inputting a user registration request provided on the vehicle 1 or operating a car navigation system in the vehicle, for example.

  In step 103, the registration execution unit 28 starts a license registration operation for storing in the electronic key 2 the expiration date and password that are written and saved in the license 19. When the license registration operation is started, for example, the vehicle 1 or the electronic key 2 may be notified by voice or text.

In step 104, the registration execution unit 28 outputs a license registration request to the verification ECU 4 to cause the verification ECU 4 to start a license registration operation.
In step 105, the verification ECU 4 switches from the “normal mode” to the “license registration mode” based on the license registration request input from the license ECU 21. When the verification ECU 4 enters the license registration mode, the verification ECU 4 enters a state where it can execute an operation of registering the expiration date and the password in the electronic key 2.

  In step 106, the registration execution unit 28 is instructed to hold the license 19 over the communication antenna 25 of the vehicle 1 when starting the license registration report operation. Monitor. At this time, the registration execution unit 28 monitors whether or not the license 19 can be detected by polling that periodically transmits polling radio waves (polling at the time of registration of an expiration date and a password). The polling at the expiration date and password registration may be started on the condition that the license registration operation is started.

  In step 107, when the license 19 is held over the communication antenna 25 of the vehicle 1 and receives a polling radio wave, communication (short-range wireless communication) is established with the communication antenna 25 and a response to polling is transmitted to the communication antenna 25. . At this time, the license 19 returns an ACK signal notifying that the polling radio wave has been received to the vehicle 1.

  In step 108, the registration execution unit 28 detects the license 19 when receiving an ACK signal within a predetermined time from the transmission of the polling radio wave. That is, the registration execution unit 28 recognizes that the license 19 is held over the communication antenna 25 of the vehicle 1.

  In step 109, the registration execution unit 28 transmits a request for reading the expiration date (authentication information Da) to the license 19 by short-range wireless communication. The expiration date read request is a notification to request that the expiration date written in the license 19 is read.

In step 110, when the license 19 receives the expiration date read request from the license ECU 21, the license 19 transmits the expiration date written in the memory unit 24 to the license ECU 21.
In step 111, the registration execution unit 28 receives the expiration date transmitted from the license 19 and reads it.

  In step 112, the registration execution unit 28 (vehicle 1) takes in the personal identification number (security data Db) of the license 19 input by the user. The input of the personal identification number is realized by, for example, inputting by a car navigation system in the vehicle or by operating and inputting vehicle-mounted devices (door handles and switches) in a predetermined order and number of times.

  In step 113, the registration execution unit 28 notifies the verification ECU 4 of the expiration date acquired from the license 19 and the personal identification number input by the user operation. That is, the registration execution unit 28 notifies the verification ECU 4 of the authentication information Da and the password data Db acquired in the registration work.

  In step 114, the verification ECU 4 transfers the expiration date and personal identification number acquired from the license ECU 21 to the electronic key 2. At this time, the expiration date and the password may be transmitted from the verification ECU 4 to the electronic key 2 by encrypted communication using an encryption key used for smart verification.

  In step 115, the electronic key 2 registers the expiration date and password received from the verification ECU 4 (vehicle 1) in itself. The expiration date and the password are written and stored in the secure element 29 of the electronic key 2. As described above, the expiration date and the password, that is, the authentication information Da and the password data Db are stored in the electronic key 2.

[Access to license information written on the license]
As shown in FIG. 3, in step 201, the information acquisition unit 30 of the license ECU 21 is subjected to an operation of holding the license 19 over the communication antenna 25 of the vehicle 1 at the start of access to the license information D1. Whether the communication with the license 19 is possible or not is monitored. At this time, the registration execution unit 28 monitors whether or not the license 19 can be detected by polling (polling when accessing license information) that periodically transmits a polling radio wave.

  In step 202, when the license 19 is held over the communication antenna 25 of the vehicle 1 and receives the polling radio wave, communication (short-range wireless communication) is established with the communication antenna 25, and a response to polling is transmitted to the communication antenna 25. . At this time, the license 19 returns an ACK signal notifying that the polling radio wave has been received to the vehicle 1.

  In step 203, the information acquisition unit 30 detects the license 19 when receiving an ACK signal within a predetermined time from the transmission of the polling radio wave. That is, the information acquisition unit 30 recognizes that the license 19 is held over the communication antenna 25 of the vehicle 1.

In step 204, the information acquisition unit 30 outputs a license information access start request to the verification ECU 4 for starting the license information access operation to the verification ECU 4.
In step 205, the verification ECU 4 executes an operation of accessing the license information D 1 written and stored in the license 19 based on the license information access request input from the license ECU 21.

  In step 206, the information acquisition unit 30 transmits an expiration date (authentication information Da) read request to the license 19. The expiration date read request is a notification to request that the expiration date written in the license 19 is read.

  In step 207, when the license 19 receives the expiration date read request from the license ECU 21, the license 19 transmits the expiration date written in the memory unit 24 to the license ECU 21. Since the expiration date is data that can be freely read out of various data stored in the license 19, the expiration date can be read from the license 19 without a password.

In step 208, the information acquisition unit 30 receives the expiration date transmitted from the license 19 and reads it.
As shown in FIG. 4, in step 209, the data acquisition unit 31 of the license ECU 21 first transfers the expiration date acquired from the license 19 to the verification ECU 4 when reading the password stored in the electronic key 2. .

  In step 210, the verification ECU 4 transmits the expiration date information to the electronic key 2 as a notification that the electronic key 2 outputs the personal identification number (password data Db). The expiration date information may be information including an expiration date acquired from the license 19 and a command for causing the electronic key 2 to read the password. The verification ECU 4 LF-transmits the expiration date information from the in-vehicle transmitter 11 (or the out-of-vehicle transmitter 10 is allowed) and causes the electronic key 2 to acquire it.

  In step 211, the electronic key 2 executes smart verification with the verification ECU 4 (vehicle 1) upon receipt of the expiration date information. When the electronic key 2 receives the notification that the smart collation is established from the collation ECU 4 and confirms that the smart collation is established, the electronic key 2 continues the process. On the other hand, the verification ECU 4 forcibly terminates the process when confirming that the smart verification is not established in the same step. In addition, the pairing confirmation of the electronic key 2 and collation ECU4 in the same step is not limited to confirmation whether smart collation is materialized, and what is necessary is just authentication which can confirm that it is a pair.

  In step 212, the electronic key 2 reads the password corresponding to the expiration date acquired from the license 19 on the condition that smart verification is established. That is, the electronic key 2 reads out and obtains the personal identification number corresponding to the expiration date obtained from the license 19 from the secure element 29.

  In step 213, the electronic key 2 transmits the read personal identification number to the verification ECU 4. At this time, the electronic key 2 performs UHF transmission of the read personal identification number from the transmission unit 17 to cause the collation ECU 4 to acquire it. The password may be transmitted from the electronic key 2 to the verification ECU 4 by encrypted communication using an encryption key used for smart verification.

In step 214, the verification ECU 4 transfers the password obtained from the electronic key 2 to the license ECU 21.
In step 215, the data acquisition unit 31 acquires the password stored in the secure element 29 of the electronic key 2 by receiving the password from the verification ECU 4. As a result, the license ECU 21 is in a state where the password is extracted from the electronic key 2 and obtained. That is, the vehicle 1 is in a state where the personal identification data Db of the license 19 that is about to be accessed is acquired.

  In step 216, the information access unit 32 of the license ECU 21 accesses the license 19 based on the password obtained from the electronic key 2. At this time, the information access unit 32 starts communication (short-range wireless communication) with the license 19 and transmits the personal identification number acquired from the electronic key 2 to the license 19.

  In step 217, the license 19 authenticates the validity of the personal identification number received from the license ECU 21 (vehicle 1). Specifically, it is confirmed whether or not the password received from the license ECU 21 matches the password stored in the memory unit 24 of the license 19. If the password authentication is successful, the process is continued. If the password authentication is not successful, the process is forcibly terminated.

  In step 218, the license 19 reads the license information D1 stored in the license 19 and transmits it to the license ECU 21 on the condition that the authentication of the personal identification number is established. The license information D1 is personal information of the user of the license 19, and includes, for example, various information such as a name, a permanent address, an address, a date of birth, a date of issue, a license condition, and a vehicle type that can be driven.

  In step 219, the license ECU 21 receives the license information D1 from the license 19 by radio. As a result, the vehicle 1 can obtain the license information D1 that is personal information from the license 19. And the vehicle 1 provides the driving environment according to each user by setting the operating state of the vehicle 1 based on the acquired license information D1.

According to the configuration of the present embodiment, the following effects can be obtained.
(1) The authentication information Da and the password data Db registered in the license 19 are stored in advance in the secure element 29 of the electronic key 2. When the vehicle 1 accesses the license information D1 of the license 19, the license information D1 is first obtained from the license 19, and the password data Db associated with the authentication information Da is taken in from the electronic key 2. Then, the license information D <b> 1 is extracted from the license 19 by accessing the license 19 based on the password data Db acquired from the electronic key 2. Therefore, when the license information D1 is fetched from the license 19, the user does not need to manually enter the password data Db manually. Therefore, the operation for reading the license information D1 from the license 19 in the vehicle 1 can be simplified.

  (2) In the electronic key 2, both the authentication information Da and the password data Db are stored in the secure element 29. Therefore, even if the authentication information Da and the password data Db are stored in the electronic key 2, security against unauthorized reading can be ensured.

  (3) The authentication information Da in this example is an expiration date generally written in the license information D1. Therefore, the license information D1 can be retrieved using the expiration date generally registered in any license 19.

  (4) After confirming the establishment of ID verification (an example is smart verification) between the vehicle 1 and the electronic key 2, the personal identification data Db of the electronic key 2 is given to the vehicle 1. Therefore, when the vehicle 1 captures the password data Db from the electronic key 2, since the ID verification between the vehicle 1 and the electronic key 2 is established, security is ensured when the password data Db is extracted from the electronic key 2. can do.

  (5) Near field communication is used for communication between the vehicle 1 and the license 19. Therefore, when the license 19 is consciously brought close to the communication antenna 25 of the vehicle 1, communication between the vehicle 1 and the license 19 is executed, so that communication is performed where the user does not intend. The situation can be made difficult to occur.

  (6) When taking the password data Db from the electronic key 2, the password data Db cannot be acquired unless the expiration date acquired from the license 19 matches the expiration date of the electronic key 2. Therefore, access to the license 19 is not executed with incorrect password data Db, so that access to the license 19 is not inadvertently locked.

(Second Embodiment)
Next, a second embodiment will be described with reference to FIG. The second embodiment is an example in which the vehicle 1 does not directly read data from the license 19 but indirectly accesses the license 19 through the license reader 41. Therefore, the same parts as those in the first embodiment are denoted by the same reference numerals, detailed description thereof is omitted, and only different parts are described in detail.

  As shown in FIG. 5, when accessing the license information D1 of the license 19, the user prepares the license reader 41 at hand. The license reader 41 can communicate with the license 19 through, for example, short-range wireless communication (near-field communication), and can also perform wireless communication with the vehicle 1. For communication between the vehicle 1 and the license reader 41, various communication modes such as near field communication (near field communication) and UHF communication can be adopted. Of course, the communication between the vehicle 1 and the license reader 41 is not limited to wireless communication but may be wired.

  Now, the license reader 41, for example, monitors whether or not it can communicate with the license 19 when the power is turned on. When the license reader 41 confirms that communication with the license 19 is established, the license reader 41 transmits a message to that effect to the vehicle 1 (license ECU 21). When the vehicle 1 receives a license presence notification from the license reader 41, the vehicle 1 outputs a license information access start request to the verification ECU 4. In addition, the license reader 41 transmits a request for reading the expiration date to the license 19, reads the expiration date from the license 19, and transmits the read expiration date to the vehicle 1 (license ECU 21).

  When the vehicle 1 receives the expiry date information of the license 19, the vehicle 1 acquires the personal identification number from the electronic key 2 through the procedure shown in steps 210 to 215 described above. The vehicle 1 transmits the personal identification number acquired from the electronic key 2 to the license reader 41 via wireless or wired communication.

  When the license reader 41 receives the password from the vehicle 1, it transmits it to the license 19. When the license 19 receives the password from the license reader 41, the license 19 performs the authentication of the password based on the received password, and confirms that the authentication is established. When the license 19 is confirmed, the license information (license information) is registered. ) Send Da to the license reader 41. The license reader 41 transfers the authentication information Da received from the license 19 to the vehicle 1. Thereby, the vehicle 1 will be in the state which has acquired the license information D1.

According to the configuration of the present embodiment, the following effects can be obtained in addition to (1) to (6) described in the first embodiment.
(7) When the vehicle 1 reads data from the license 19, the license 19 is accessed through the license reader 41, so this type of communication function need not be installed in the vehicle 1.

(Third embodiment)
Next, a third embodiment will be described with reference to FIG. In this example, only parts different from the first and second embodiments will be described.

  As shown in FIG. 6, the secure element 29 of the electronic key 2 stores not only the whole password data Db but only a part Db-1 thereof. The other part Db-2 of the password data Db is managed by another device 42. The other device 42 can communicate with the vehicle 1 (license ECU 21) through wireless or wired communication. The other device 42 includes, for example, a dedicated tool for license information access and a center for managing and managing license information. In addition, when the vehicle 1 communicates with a center, it is good to implement through the vehicle-mounted G-Book function etc., for example.

  Now, when the license ECU 21 obtains the expiration date information from the license 19, the operation shifts to an operation of taking the password data Db from the electronic key 2. In this example, first, a part Db of the password data Db from the electronic key 2 is entered. -1 is acquired. Subsequently, the vehicle 1 acquires another part Db-2 of the password data Db from the other device 42. When all of the password data Db (Db-1, Db-2) are prepared, the vehicle 1 accesses the license 19 based on this and acquires the license information D1 from the license 19.

According to the configuration of the present embodiment, in addition to (1) to (7) described in the first and second embodiments, the following effects can be obtained.
(8) Even if the password data Db is stored in the electronic key 2, only a part Db-1 of the password data Db has to be registered, so that security against theft of the password data Db can be ensured. It will be advantageous.

Note that the embodiment is not limited to the configuration described so far, and may be modified as follows.
In each embodiment, the pair confirmation communication (smart verification) in step 101 may be performed during the registration operation.
