Description

  The present invention generally relates to a vehicle anti-theft system and vehicle anti-theft device using an immobilizer system, and more particularly, requires additional user registration in a database outside the vehicle for additional registration of authorized users, and immobilizer expiration date. The present invention relates to a vehicle anti-theft system and a vehicle anti-theft device.

  As a vehicular security system, an immobilizer (electronic movement lock device) mainly for theft prevention is known. Immobilizers have been required to be installed as standard in Europe since 1997, and the number of vehicles equipped in Japan is increasing.

  In an immobilizer, a small electronic communication chip called a transponder is embedded in the engine key (grip part) of the vehicle, and when the engine key is inserted into the key cylinder on the vehicle side, the ID code recorded in advance on the transponder is the key cylinder. It is transmitted to the antenna attached to and read. The read ID code is collated with an ID code held in advance by the ECU on the vehicle side. If these ID codes match, the used engine key is the authorized engine key, and it is authenticated that it is used by the authorized user, and engine ignition and fuel injection are permitted. On the other hand, when the ID code of the engine key does not match the ID code on the vehicle side, ignition of the engine and fuel injection are not permitted, and the engine cannot be started using the engine key.

In such an immobilizer system, an expiration date can be set for the ID code, and a system that cannot release the immobilizer when the set expiration date has passed even if it is a regular engine key unless an update operation is performed. It has been proposed (see, for example, Patent Document 1).
JP 2003-64920 A

  However, in the conventional immobilizer system with an expiration date described in Patent Document 1, the expiration date management is completed locally in the vehicle, and the expiration date of the subkey is set by confirming the ID code of the master key (ie, Key registration (additional registration) and renewal (extension) are possible. For this reason, it is not clear who set / updated the subkey, and if the expiry date of the subkey is set / updated by an unauthorized third party (for example, the vehicle stealing / obfusor makes the subkey If it is forced to set or update the system, it is not possible to specify who the unauthorized third party is.

  On the other hand, when a regular user updates the expiration date during normal times, a predetermined operation is required, which may give an impression that it is complicated and not convenient.

  The present invention is to solve such a problem, and the vehicle theft in which the user registration in the database outside the vehicle is essential for the additional registration of the authorized user and the immobilizer expiration date is automatically updated. It is a main object to provide a prevention system and a vehicle antitheft device.

The first mode for achieving the above object is mounted on a vehicle, has a communication function, and when a user ID code acquired from a user matches a verification ID code registered in the vehicle in advance An in-vehicle device control device (or a vehicle antitheft device) that permits operation of a predetermined in-vehicle device of the vehicle;

  In the first aspect, the predetermined in-vehicle device is, for example, a device (ignition device, fuel injection device, engine ECU, etc.) related to the operation of a power source such as an engine.

  In the first aspect, the predetermined storage device may be provided locally in the communication station or may be provided in a remote connected by communication.

  According to the first aspect, additional registration of a regular user is possible only when user information of a vehicle user to be newly registered is stored in a predetermined storage device (for example, a database) outside the vehicle. Even if an unauthorized third party such as a vehicle stealer / torner forces the authorized user to perform additional registration, the additional registration cannot be completed only by the vehicle local, and unauthorized authorized user additional registration is suppressed, Even if additional registration by an unauthorized third party is made, the identity can be easily identified from the user information stored in a predetermined storage device outside the vehicle.

  Therefore, in this first aspect, the user information is preferably data including personal information sufficient to refer to the identity of the user, such as an address, name, date of birth, and the like. The means is realized by, for example, an image reading apparatus that reads an identification card such as a driver's license as an image.

  In this first aspect, the in-vehicle device control device further includes code management means for setting and managing an expiration date for the verification ID code, and the code management means is configured to control the vehicle by the user authentication means. When the user is authenticated as an authorized user of the vehicle, if the expiration date set in the ID code for verification corresponding to the user ID code of the user is automatically updated, no user operation is required. Since user authentication is performed and the expiration date of the ID code is automatically updated, user convenience is improved.

  For such user authentication that does not require user operation, for example, the user authentication means uses biometric authentication (biometric authentication) based on individual differences such as fingerprints, voiceprints, faces, irises, retinas, palm veins, etc. Alternatively, it is realized by receiving a predetermined ID signal (for example, by a card reader) from a wireless transmitter (for example, a non-contact IC card) held by the vehicle user and collating it with an ID signal of a regular user held in advance.

The second aspect of the present invention for achieving the above object is mounted on a vehicle, has a communication function, and a user ID code acquired from a user matches a verification ID code registered in the vehicle in advance. An antitheft device for a vehicle that permits operation of a predetermined in-vehicle device of the vehicle,

User information acquisition means for acquiring user information of a vehicle user newly registered as a regular user of the vehicle;
Transfer means for transferring the user information of the newly registered vehicle user acquired by the user information acquisition means when the authorized user is authenticated by the user authentication means to a first communication station;
Corresponding to the user ID code acquired from the newly registered vehicle user when receiving a signal notifying that the user information of the newly registered vehicle user is stored in a predetermined storage device from the second communication station It is a vehicle antitheft device having code registration means for newly registering a verification ID code.

  In the second aspect, the predetermined in-vehicle device is, for example, a device (ignition device, fuel injection device, engine ECU, etc.) related to the operation of a power source such as an engine.

  In the second aspect, the first and second communication stations may be the same communication station, and the predetermined storage device is one of the first and second communication stations. It may be provided locally or it may be provided in a remote connected communication.

  According to the second aspect, additional registration of a regular user is possible only when user information of a vehicle user to be newly registered is stored in a predetermined storage device (for example, a database) outside the vehicle. Even if an unauthorized third party such as a vehicle stealer / torner forces the authorized user to perform additional registration, the additional registration cannot be completed only by the vehicle local, and unauthorized additional user additional registration is suppressed, Even if additional registration by an unauthorized third party is made, the identity can be easily identified from the user information stored in a predetermined storage device outside the vehicle.

  Therefore, in the second aspect, the user information is preferably data including personal information sufficient to refer to the identity of the user such as address, name, date of birth, etc. The means is realized by, for example, an image reading apparatus that reads an identification card such as a driver's license as an image.

  In this second aspect, the vehicle antitheft device further includes code management means for setting and managing an expiration date for the verification ID code, and the code management means is configured by the user authentication means. When the vehicle user is authenticated as an authorized user of the vehicle, if the expiration date set in the ID code for verification corresponding to the user ID code of the user is automatically updated, no user operation is required. Since user authentication is performed and the expiration date of the ID code is automatically updated, user convenience is improved.

  For such user authentication that does not require user operation, for example, the user authentication means uses biometric authentication (biometric authentication) based on individual differences such as fingerprints, voiceprints, faces, irises, retinas, palm veins, etc. Alternatively, it is realized by receiving a predetermined ID signal (for example, by a card reader) from a wireless transmitter (for example, a non-contact IC card) held by the vehicle user and collating it with an ID signal of a regular user held in advance.

  According to the present invention, it is possible to provide a vehicle anti-theft device in which user registration is essential for setting / updating the expiration date of an immobilizer and the update process is automatically performed.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the accompanying drawings. Note that the basic concept, main hardware configuration, operating principle, basic control method, and the like of the vehicle antitheft device using an immobilizer are known to those skilled in the art, and detailed description thereof is omitted.

  An embodiment of the present invention will be described with reference to FIG. FIG. 1 is a schematic diagram of a vehicle antitheft system according to this embodiment.

  A vehicle-mounted device control device (vehicle antitheft device) 101 mounted on a vehicle includes a communication unit 102, a control unit 103 such as an ECU, an image capturing unit 104 such as a camera and a scanner, and a vehicle operator's It includes a sensor unit 105 for biometric authentication that senses biometric features, and a reader unit 106 that is an IC card reader that reads a transmission signal from a non-contact IC card held by a vehicle operator.

  The communication unit 102 communicates with a center (communication station) 107 that is an authorized organization and capable of wireless communication. The center 107 includes a user information database (DB) 108 that stores user information of authorized users transmitted from the vehicle.

  The control unit 103 is a controller that controls the immobilizer system, and compares the user ID code recorded in advance in the transponder of the engine key inserted into the key cylinder on the vehicle side with a verification ID code that is stored in advance. If they do not match, the engine ECU or the like has a function of issuing a command to prohibit engine start.

  The control unit 103 also has a function of setting and managing an expiration date for the immobilizer ID code. That is, an ID code with an expiration date greater than 0 is made available, and an ID code with an expiration date set to 0 is disabled. In addition, the ID code for which the set expiration date has passed is invalidated and the expiration date of the ID code updated within the expiration date is extended.

  Further, the control unit 103 has a function of authenticating a regular user by collating data on a biological feature or ID signal obtained from the sensor unit 105 or the reader unit 106 with data of a regular user stored in advance. In the present embodiment, the above-mentioned ID code expiration date is automatically updated by authenticating a regular user using the sensor unit 105 and / or the reader unit 106 periodically or at any predetermined timing. Done.

  The image capturing unit 104 captures, as image information, a driver's license or other identification card of a person who intends to become an authorized user of the vehicle (hereinafter simply referred to as “new user”), and stores the image data. The user information about the new user is passed to the control unit 103.

  The sensor unit 105 detects predetermined biological characteristics (for example, fingerprint, voice print, face, iris, retina, palm vein, etc.) of the vehicle operator according to the type of biometric authentication used.

  The installation location of the sensor unit 105 may be an arbitrary location in the passenger compartment. For example, it is provided on the instrument panel for face / iris / retinal authentication, and on the steering wheel / shift lever for fingerprint / palm vein authentication, so that the vehicle operator does not need to be aware of it, that is, without user operation. A predetermined biological feature of the vehicle operator can be sensed. The biometric feature of the vehicle operator sensed by the sensor unit 105 is sent to the control unit 103 and collated with the biometric feature of the authorized user recorded in advance.

  The reader unit 106 is a non-contact card reader, and its communication distance is assumed to be about several tens of centimeters. Therefore, the reader unit 106 is installed in a plurality of locations such as a driver seat, a passenger seat, and a dash panel. . As a result, the vehicle operator puts the IC card in the pocket of the clothes, etc., and the ID signal is read from the IC card held by the vehicle operator without making the vehicle operator aware of it, that is, without user operation. be able to. The read ID signal is sent to the control unit 103 and collated with the ID signal of the authorized user held in advance.

  The in-vehicle device control apparatus 101 according to the present embodiment has the above configuration. Next, in this embodiment, a process when a new authorized user is registered in the in-vehicle device control apparatus 101 will be described.

  Here, to register a new authorized user of a vehicle that can release the immobilizer system and start a power source such as an engine, that is, the engine key of the vehicle user who intends to newly register the vehicle. This means that the ID code corresponding to the ID code stored in the transponder is recognized and held for the authorized user.

  First, since only the authorized user can perform the additional registration process of authorized users, the sensor unit 105 and / or the reader unit 106 authenticates that the operator is an authorized user.

  Once authenticated as a legitimate user, then the legitimate user and / or the new user can be fully inquired of the new user, for example, by voice from a speaker (not shown) and / or visually from a display (not shown). Presentation of an identification card (such as a driver's license) is requested, and the image capture unit 104 captures an image of a new user's identification card.

  The control unit 103 transmits user information of the new user obtained from the image capturing unit 104 to the center 107 via the communication unit 102 and requests user registration. When the center 107 receives the user information from the in-vehicle device control apparatus 101, the center 107 determines whether or not the content of the user information includes information sufficient to specify the identity of the target person. If the identification information is sufficient, the received user information is stored in the user information database 108, and a notification signal indicating that the user registration is completed is returned to the in-vehicle device control apparatus 101. If the information is insufficient to identify the identity, the in-vehicle device control device 101 is notified that the user registration is impossible.

  When the control unit 103 receives a signal indicating the completion of user registration from the center 107 via the communication unit 102, the control unit 103 handles the ID code of the new user as the ID code of the authorized user. That is, when the new user inserts the engine key into the key cylinder, the engine is permitted to start. Conversely, unless a signal indicating the completion of user registration is received from the center 107, the control unit 103 does not permit additional registration of a new regular user.

  When the user is additionally registered as a regular user, the biometric feature and / or ID signal of the new user is also captured using the sensor unit 105 and / or the reader unit 106 for the expiration date update.

  As described above, according to the present embodiment, if user information is not registered in the database outside the vehicle, additional registration as a regular user is not performed, so that unauthorized regular user additional registration is suppressed and temporary additional registration is temporarily performed. However, the identity can be easily identified from the user information stored in the database outside the vehicle.

  Further, according to the present embodiment, since the expiration date set in the ID code of the immobilizer system is automatically updated when the authorized user is authenticated, for example, when the authorized user is driving the vehicle, No user operation is required, improving user convenience.

  In the present embodiment, the case where the in-vehicle device control apparatus 101 communicates with the predetermined communication station 107 has been described. However, the present invention is not limited to this, and the registration request transmission destination of the in-vehicle apparatus control device 101 and the registration completion are registered. The transmission source may be a different communication station.

  In this embodiment, the case where the user information database 108 is provided locally in the communication station 107 has been described. However, the present invention is not limited to this, and the database 108 is remotely connected to the communication station 107. It may be provided.

  Moreover, although the present Example demonstrated the case where the vehicle equipment control apparatus 101 was provided with the sensor part 105 and the reader part 106, this invention is not restricted to this, You may make it provide only any one. That is, only one of the user authentication methods may be used.

  The present invention can be used for a vehicle antitheft system and a vehicle antitheft device. The appearance, weight, size, running performance, etc. of the target vehicle are not limited.
