2. Description of the Related Art Conventionally, various techniques have been developed to prevent theft of a vehicle. For example, in Japanese Patent Application Laid-Open No. 2000-16250, in an automobile equipped with an automatic theft display operation, when a door is opened without key operation, a display device is activated and stored in an IC card by a wireless transmission device. Has been proposed to transmit predetermined information.
It is not always enough to prevent theft.

If a vehicle is stolen, the surveillance camera installed on the road reads the vehicle's license plate and searches for the stolen vehicle. If the plate is forged, there is a problem that it is difficult to find the vehicle.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and provides a vehicle theft prevention device and a vehicle theft prevention system which can prevent theft of a vehicle and easily detect a stolen vehicle. The purpose is to do.

[0005]

Means for Solving the Problems and Effects of the Invention (1) According to the first aspect of the present invention, the ID stored in the electronic license plate (the vehicle ID for distinguishing the own vehicle from other vehicles) and the key stored in the key are stored. It is determined whether the ID (key ID) matches with
If it is determined that the two IDs do not match, for example, the operation of the vehicle is disabled by preventing the engine from starting or changing from the P range.

In other words, if the key is not correct, the vehicle cannot be driven, so that theft of the vehicle can be prevented. In this case, the driving is prohibited when the IDs do not match. However, the same effect can be obtained even when the driving is permitted when the IDs match.

(2) In the invention of claim 2, the ID of the electronic driving license (license ID indicating who is the license) is registered in advance in the ECU or the like on the vehicle side. Then, the electronic driver's license ID is used by the electronic driver's license reader.
Is read, it is determined whether the new license ID matches the registered proper license ID,
If it is determined that the two IDs do not match, the vehicle cannot be driven.

That is, if the electronic driver's license is not a registered proper one, the vehicle cannot be driven, so that the theft of the vehicle can be prevented. In this case, the driving is prohibited when the IDs do not match.
Even when driving is permitted when D matches, the same effect is obtained.

(3) According to a third aspect of the present invention, there is provided the vehicle according to the first or second aspect of the present invention, wherein the vehicle ID is provided.
If the key ID and key ID do not match, and the registered license ID and the new license ID do not match, the driving of the vehicle is disabled. That is, in the present invention, driving is prohibited only when the IDs do not match in both of the determinations. Therefore, when the driving is actually prohibited, the possibility of theft is high, and it is possible to prevent erroneous determination that the vehicle is not stolen but is determined to be theft.

(4) In the invention according to claim 4, when the driving is prohibited by the driving prohibiting means, the fact is described as follows.
It is transmitted to an external device together with the ID of the electronic license plate. Therefore, for example, the management center side knows that an abnormality has occurred in the vehicle, and by reporting this to the police or the like, theft of the vehicle can be prevented.

(5) According to the fifth aspect of the invention, when the driving is prohibited by the above-mentioned driving prohibiting means, the occurrence of the abnormality is notified to the surroundings by an alarm sound or blinking light, so that the vehicle is stolen. Can be prevented. (6) The invention of claim 6 satisfies both the judgment conditions of claim 1 and claim 2, wherein the vehicle ID and the key ID match, and the registered license ID and new license Certificate ID
If they match, the operation of the vehicle is permitted.

In other words, according to the present invention, the conditions for permitting the driving of the vehicle are stricter than those of the first and second aspects of the invention. If at least one of the conditions is not satisfied, the vehicle cannot be driven, so that the vehicle is stolen. Can be effectively prevented. (7) In the invention of claim 7, the ID (vehicle ID) stored in the electronic license plate and the ID stored in the key
(Key ID) is determined to be coincident. If it is determined that the two IDs do not coincide with each other, it is determined that an abnormality has occurred, and the content of the abnormality together with the ID of the electronic license plate is transmitted to an external device. Send to

Therefore, for example, it is known that an abnormality has occurred in the vehicle on the management center side. By contacting the police or the like or tracking the vehicle by using a road monitoring system, the vehicle can be monitored. Can be prevented from being stolen. (8) In the invention of claim 8, the ID of the electronic driving license (license ID) is registered in advance in the ECU or the like on the vehicle side. When the electronic driver's license ID is newly read by the electronic driver's license reading device, it is determined whether or not the license ID matches the registered proper license ID. If it is determined that the IDs do not match, it is considered that an abnormality has occurred, and the content of the abnormality is transmitted to an external device together with the ID of the electronic license plate.

Therefore, for example, it is known that an abnormality has occurred in the vehicle on the management center side. The vehicle is notified by contacting the police or the like, or by tracking the vehicle using a road monitoring system. Can be prevented from being stolen. (9) The invention of claim 9 is provided with both the judgment conditions of claim 6 and claim 7, wherein the vehicle ID and the key ID do not match, and the registered license ID and the new License I
If D does not match, it is considered that an abnormality has occurred,
The contents of the abnormality are transmitted to an external device together with the ID of the electronic license plate.

That is, in the present invention, the conditions for permitting transmission of an abnormality are stricter than those of the above-described inventions. Therefore, when an abnormality occurs, the possibility of theft is high, and theft is not theft. Erroneous determination of the determination can be prevented. (10) According to the tenth aspect of the present invention,
It is determined whether the electronic driver's license is set in the electronic driver's license reader so that the information can be read. If it is determined that the setting has not been made, it is determined that an abnormality has occurred, and the content of the abnormality is transmitted to an external device together with the ID of the electronic license plate.

Therefore, for example, it is known that an abnormality has occurred in the vehicle on the management center side. By contacting the police or the like or tracking the vehicle using a road monitoring system, the vehicle can be monitored. Can be prevented from being stolen. (11) According to the eleventh aspect of the present invention, when a content indicating an abnormality is transmitted from the vehicle to the external device, the external device notifies the external device.

For example, a display monitored by the operator indicates that an abnormality has occurred in the vehicle. Therefore, the operator can prevent theft by contacting the police or the owner based on the information.

(12) According to the twelfth aspect of the invention, when the content indicating abnormality is transmitted from the vehicle side to the external device, the transmitted content is stored in advance in the external device. With reference to the stolen vehicle information, a search is made for a stolen vehicle that matches the transmitted content. For example, the ID of the electronic license plate that has transmitted the abnormality is searched by searching the database of the stolen vehicle, and if it is found,
By contacting the police or tracking a stolen vehicle using a road monitoring system, theft is prevented.

In the invention described above, each term has the following meaning. The driving prohibiting means for prohibiting the driving of the vehicle includes a process for prohibiting the starting of the engine or prohibiting the change from the P range. In addition, in the case of a vehicle powered by an electric motor, there is a process of not supplying power to the electric motor. When the abnormality occurs, for example, a process of notifying an abnormality to the surroundings includes a process of sounding an alarm. , A process of displaying a warning on a monitor such as a dashboard, a process of displaying a warning outside the vehicle (for example, blinking a hazard lamp), and displaying a warning to surrounding vehicles.

The electronic driver's license is a license in which information for specifying a person who is qualified for driving (license ID), a vehicle that can be driven, and information such as an expiration date are recorded as electronic information. It is. For example, a wireless electronic driver's license (which has a function of transmitting information wirelessly), a magnetic card (which stores information by magnetic recording and is read by a magnetic card reader), and a contact IC card (including a contact, There is a card that can read information from a contact point of a reader in contact with the contact), a short-distance reading type card (a card that receives a power supply radio wave and wirelessly transmits information by using the power).

As the electronic driver's license reading device, for example, there is a device having a function of receiving a radio signal for a wireless electronic driver's license, and a portable information member of a magnetic card type. There is a magnetic card reader, and for a contact type IC card type portable information member, there is a type in which an IC card with a contact is inserted and information is read from a contact that comes into contact with the contact. Some members have a function of transmitting power supply radio waves and a function of wireless reception.

On the other hand, the roadside system is a roadside monitoring system 23 having a communication device 21 arranged along the road.
And a management center 25 connected to the road monitoring system 23 via a network.

Hereinafter, each component will be described in detail. The vehicle key (ID built-in key) 3 is provided with an IC having a memory 3a. The memory 3a has an ID indicating the vehicle (ie, a key ID indicating which vehicle key 3 is used). ) Is stored. Here, the key ID is the same as the vehicle ID.

When the key 3 is inserted into the ignition switch, the key ID reading device 5
Is a device that reads the key ID from
C reading device. The electronic driver's license 7 includes information on a person who holds a driver's license, information on what kind of vehicle may be driven, an expiration date, and the like as electronic information.
a is an IC card recorded in a. In this memory 7a,
A license ID indicating which driver's license is stored is stored.

The electronic driver's license reading device 9 is a device that can read the contents of the memory 7a of the electronic driver's license 7 when the electronic driver's license 7 is set,
This is a so-called non-contact IC reader. In this embodiment,
The license ID indicating the distinction of the electronic driver's license 9 is read.

As shown in FIG. 2, the electronic driver's license reading device 9 is provided with a password input unit 10 used when registering the electronic driver's license 7 in the ECU 1.
The password input unit 10 includes a registration button 10a, a numeric keypad 10b, and a display unit 10c.

The electronic license plate 11 includes a memory 11a for storing information corresponding to the number of a conventional license plate, that is, a vehicle ID for identifying a vehicle, and a vehicle ID.
And a radio module 11b which is a communication device for transmitting and receiving information such as information to and from the road monitoring system 23.
The electronic license plate 11 and the road monitoring system 23
For example, DSRC communication is used for the communication between.

The engine start control circuit 13 is a circuit that controls the normal start of the engine and prohibits the start of the engine if there is an abnormality as a result of the ID determination described later. The warning alarm generating device 15 is a device that can generate a warning by sound or light when there is an abnormality as a result of the ID determination.

The transmission control circuit 17 comprises:
This circuit can control normal range switching and can prohibit range switching (for example, switching from the P range) if there is an abnormality as a result of ID determination. The ECU 1 connected to each of the above-described devices includes a memory 1a and an ID collating circuit 1b.
The ID collating circuit 1b checks whether the IDs sent from the key ID reader 5 and the electronic license plate 11 match or not, and is read by the registered license ID and the electronic driver's license reader 9. A check is made for a match / mismatch between the license IDs. Further, the ECU 1 outputs a control signal to the engine start control circuit 13, the warning alarm generation device 15, and the transmission control circuit 17.

On the other hand, in the system on the external device side,
A host computer 27 is disposed in the management center 25, and a memory 27a of the host computer 27 is provided.
Stores a database about a stolen vehicle. b) Next, processing performed in the communication system of the present embodiment will be described.

Electronic Driver's License Registration Process This process is a process of registering the electronic driver's license 7 on the vehicle side in the vehicle-mounted system. As shown in the flowchart of FIG. 3, in step 100, it is determined whether or not the electronic driving license 7 is set in the electronic driving license reading device 9. If the determination is affirmative, the process proceeds to step 110, whereas if the determination is negative, the process ends once.

In step 110, it is determined whether the registration button 10a has been pressed. If the determination is affirmative, the process proceeds to step 120, whereas if the determination is negative, the process ends once. In step 120, it is determined whether or not a password has been input using the numeric keypad 10b. If the determination is affirmative, the process proceeds to step 130, whereas if the determination is negative, the process proceeds to step 160.

In step 130, it is determined whether the input password is correct. If the determination is affirmative, the routine proceeds to step 140, whereas if the determination is negative, the routine proceeds to step 160. In step 140, since the correct password has been entered, the memory 7a of the electronic driver's license 7
Reads the license ID stored in the ECU 1 into the ECU 1,
It is stored in the memory 1a of the ECU 1. That is, the ID of the electronic driving license appropriate for driving the vehicle is stored in the vehicle in advance.

If another license ID has already been registered, this process updates and registers it with a new license ID. In the following step 150, the completion of the registration is displayed on the display unit 10c, and the present process is ended once.

On the other hand, in step 160, the fact that registration is not possible is displayed on the display unit 10c, and the present process is terminated once. Anti-theft processing This processing is to prevent the vehicle from being stolen by checking each ID in the in-vehicle system and, if the ID does not match, prohibiting the vehicle from running or transmitting the fact. This is the process.

As shown in the flowchart of FIG. 4, the ignition switch is turned to Acc (power supply O) by the key 3.
When operated in the state of N), in step 200, the ECU 1 as the control unit is started. In the following step 210, the key ID is read from the memory 3a of the key 3 by the key ID reading device 5 and the memory 1a of the ECU 1 is read.
To memorize. This key ID is a vehicle I indicating the distinction of the vehicle.
Same as D.

In the following step 220, the vehicle ID is read from the memory 11a of the electronic license plate 11,
It is stored in the memory 1a of the ECU 1. Next step 230
Then, it is determined whether or not the key ID read in step 210 and step 220 matches the vehicle ID. If the determination is affirmative, the process proceeds to step 240, whereas if the determination is negative, the process proceeds to step 340.

In step 240, the manual vehicle (MT
Car) or an automatic car (AT car). If it is determined that the vehicle is a manual vehicle, the process proceeds to step 250.
If it is determined that the vehicle is an automatic vehicle, the routine proceeds to step 260. In step 250, a driving permission process for the manual vehicle is performed.

More specifically, step 252 in FIG.
As shown in (1), an engine start permission command (for example, permission of ignition or fuel supply) is output to the engine start control circuit 13. As a result, the ignition switch
When it becomes N, the engine can be started.

On the other hand, in step 260, a driving permission process for the automatic vehicle is performed. Specifically, as shown in step 262 of FIG.
Then, an engine start permission command (for example, permission of ignition or fuel supply) is output. Thus, the engine can be started when the ignition switch is turned on. In the subsequent step 264, a P range lock release permission command is output to the transmission control circuit 17. As a result, a range change (change from the P range) becomes possible.

Thereafter, in step 270 of FIG. 4, it is determined whether or not the electronic driving license 7 is set in the electronic driving license reading device 9. If an affirmative determination is made here, the process proceeds to step 280;
Go to 20. In step 320, since the electronic driver's license 7 is in an abnormal state in which the electronic driver's license 7 is not set, information indicating that the electronic driver's license 7 is not read is associated with the vehicle ID in order to transmit the fact. Is set on the electronic license plate 11 (to enable transmission).

On the other hand, in step 280, the electronic driver's license reading device 9 converts the electronic driver's license 7 into the license ID.
Read. In the following step 290, it is determined whether or not the license ID newly read this time matches a registered (proper) license ID. If the determination is affirmative, the process proceeds to step 300, whereas if the determination is negative, the process proceeds to step 310.

In step 300, vehicle information is set on the electronic license plate 11. Here, since everything is in a normal state, it is assumed that the vehicle ID can simply be transmitted. On the other hand, in step 310, the registered license ID
And the newly read license ID are inconsistent with each other. In order to transmit the information, information indicating that the license ID does not match is associated with the vehicle ID, and the electronic license plate 11 Set (to enable transmission).

In the following step 330, if communication with the road monitoring system 23 becomes possible, the information set on the electronic license plate 11 is transmitted to the road monitoring system 2
3 and the process is once terminated. For example, key ID
If the registered license ID and the newly read license ID match, there is no abnormality, so only the vehicle ID is transmitted from the electronic license plate 11. .

For example, if the key ID matches the vehicle ID and the registered license ID does not match the newly read license ID, it is determined that there is an abnormality, and the electronic number is determined. The plate 11 transmits that the vehicle ID and the license ID do not match.

Further, for example, when the key ID and the vehicle ID match and the electronic driver's license 7 is not set, it is determined that there is an abnormality, and the electronic license plate 1
1 transmits that the vehicle ID and the license ID cannot be read. On the other hand, in step 340, to which a negative determination is made in step 230, the warning process is performed because the key ID does not match the vehicle ID, that is, since the incorrect key 3 has been used. For example, a warning alarm generator 1
5 is driven to generate an alarm sound.

At this time, the use of the incorrect key 3 may be communicated to the road monitoring system 23 using the electronic license plate 11. In the following step 350, it is determined whether the vehicle is a manual vehicle or an automatic vehicle. Here, if it is determined that the vehicle is a manual vehicle, the process proceeds to step 360, while if it is determined that the vehicle is an automatic vehicle, the process proceeds to step 370.

In step 360, a driving prohibition process for the manual vehicle is performed. Specifically, as shown in step 362 of FIG.
An engine start disabling command (for example, prohibiting ignition or fuel supply) is output. This makes it impossible to start the engine even when the ignition switch is turned on.

On the other hand, in step 370, a driving prohibition process for the automatic vehicle is performed. Specifically, as shown in step 372 of FIG.
Then, an engine start non-permission command (for example, prohibiting ignition or fuel supply) is output. This makes it impossible to start the engine even when the ignition switch is turned on. In the subsequent step 374, a P range lock release non-permission command is output to the transmission control circuit 17. This makes it impossible to change the range.

Vehicle Management Processing This processing is performed when there is an abnormality such as unused electronic driver's license 7 in the system on the external device side. As shown in the flowchart of FIG.
The electronic license plate 1 by the road monitoring system 23
1 is communicated.

In the following step 410, it is determined whether or not communication with the electronic license plate 11 has been successful. If the determination is affirmative, the process proceeds to step 420, while if the determination is negative, the process proceeds to step 520. In step 520, since the communication has failed, it is determined that the data (for example, the vehicle ID) acquired in the current communication is incomplete, and the data is discarded, and the process is terminated once.

On the other hand, in step 420, the communication is successful, so that the on-road monitoring system 23 allows the various types of vehicle information from the electronic license plate 11 (whether or not the vehicle ID and the key ID match, whether the electronic driver's license 7 With or without set,
Since information such as whether or not the electronic driver's license 7 matches can be obtained, the communication is connected to the host computer 27 of the management center 25 in order to communicate them.

In the following step 430, the management center 2
In addition to the above-mentioned vehicle information, the information of the position of the road monitoring system 23 is transmitted to the host computer 27 of No.5. In the following step 430, the host computer 27
Based on the transmitted information, it is determined whether the electronic driver's license 11 is not set in the electronic driver's license reader 9 and the license ID cannot be read. If the determination is affirmative, the process proceeds to step 460, while if the determination is negative, the process proceeds to step 450.

In step 450, it is determined whether or not the newly read license ID is an unregistered (inappropriate) license ID based on the transmitted information. If the determination is affirmative, the process proceeds to step 460. If the determination is negative, the process proceeds to step 510.

In step 510, since the electronic driver's license 7 is set and its license ID matches the registered one, that is, the read license ID is correct and there is no abnormality. Therefore, a process for using VICS (registered trademark) or the like as normal vehicle information is performed, and the process is temporarily terminated.

On the other hand, in step 460, since the electronic driver's license 7 is not set or the license ID is unregistered, that is, it is considered that some abnormality has occurred. Is displayed on the display of the management center 25.

Therefore, the operator looks at this display,
The owner of the vehicle in question can be contacted to hear the situation. In the following step 470, a process of searching the stolen vehicle data of the host computer 27 for data of the corresponding vehicle (for example, vehicle ID) is performed.

In the following step 480, it is determined whether or not the vehicle is a stolen vehicle based on the result of the search.
If the determination is affirmative, the process proceeds to step 490, while if the determination is negative, the process proceeds to step 510. Step 4
At 90, since the searched vehicle is a stolen vehicle, the vehicle is tracked using the road monitoring system.

In the following step 500, the police department is notified that the vehicle is stolen, and the process is terminated once. c) In the present embodiment, the following effects are obtained by the above-described configuration. In the present embodiment, when the key ID stored in the key and the vehicle ID stored in the electronic license plate do not match, the operation of the vehicle is prohibited by prohibiting the start of the engine or the change of the range. , The vehicle can be prevented from being stolen.

In addition to the present embodiment, the registered license I
If D and the newly read license ID do not match,
The vehicle may not be driven. Thus, even if the key 3 is stolen, the vehicle can be prevented from being stolen. Furthermore, if the key ID and the vehicle ID do not match, and the registered license ID does not match the newly read license ID, the vehicle may not be driven. In this case, the abnormality can be reliably detected, so that if there is an abnormality, it can be determined that the vehicle is stolen with a higher probability.

In this embodiment, the registered license I
If D and the newly read license ID do not match, the abnormal state is transmitted to the management center 25. Therefore, it is determined whether the corresponding vehicle is a stolen vehicle by referring to the stolen vehicle database. It can be detected immediately.
Therefore, if the vehicle is stolen, the road monitoring system 2
The trajectory 3 can be used to find a stolen vehicle or to crack down on a stolen vehicle.

In addition, if the key ID does not match the vehicle ID and the registered license ID does not match the newly read license ID, the abnormal state is transmitted to the management center 25. You may make it. In this case, the abnormality can be reliably detected, so that if there is an abnormality, it can be determined that the vehicle is stolen with a higher probability. (Embodiment 2) Next, Embodiment 2 will be described, but description of the same parts as in Embodiment 1 will be omitted.

In this embodiment, when the registered license ID and the newly read license ID do not match, driving of the vehicle is prohibited. Hereinafter, the processing in this embodiment will be described with reference to the flowchart in FIG.

As shown in FIG. 7, in step 600, the ECU 1 as a control unit is started. In the following step 610, it is determined whether or not the electronic driving license 7 is set in the electronic driving license reading device 9. If the determination is affirmative, the process proceeds to step 620, and if the determination is negative, the process ends once.

In step 620, the license ID is read from the electronic driving license 7 by the electronic driving license reading device 9. In the following step 630, it is determined whether or not the newly read license ID matches an already registered (proper) license ID. If an affirmative determination is made here, the process proceeds to step 640;
Go to 80.

In step 640, a sound notifies that verification has been completed normally because both license IDs match.
In the following step 650, it is determined whether the vehicle is a manual vehicle (MT vehicle) or an automatic vehicle (AT vehicle). Here, if it is determined that the vehicle is a manual vehicle, the process proceeds to step 660. If it is determined that the vehicle is an automatic vehicle, the process proceeds to step 670.

In step 660, as in the first embodiment, a driving permission process for the manual vehicle is performed, and the process is temporarily terminated. On the other hand, in step 670, as in the first embodiment, a driving permission process for the automatic vehicle is performed, and the process is once ended.

Further, in step 680, to which the operation proceeds after making a negative determination in step 630, the license IDs are in an abnormal state where they do not match.
Sound an alarm. In the following step 690, it is determined whether or not the license ID has been registered. If the determination is affirmative, the process proceeds to step 700, whereas if the determination is negative, the process proceeds to step 740.

In step 700, it is determined whether or not the license ID is to be registered again, for example, based on whether or not a predetermined button has been pressed. If a positive determination is made here, step 74 is reached.
If the determination is negative, the process proceeds to step 710. In step 710, it is determined whether the vehicle is a manual vehicle (MT vehicle) or an automatic vehicle (AT vehicle). Here, if it is determined that the vehicle is a manual vehicle, the process proceeds to step 720. If it is determined that the vehicle is an automatic vehicle, the process proceeds to step 730.

In step 720, as in the first embodiment, a driving prohibition process for the manual vehicle is performed, and the process is terminated once. On the other hand, in step 730, as in the first embodiment, the driving prohibition process for the automatic vehicle is performed, and the process is temporarily ended.

In step 740, it is determined whether or not the electronic driving license 7 has been set in the electronic driving license reading device 9 in order to register the license ID. If an affirmative determination is made here, the process proceeds to step 740. On the other hand, if a negative determination is made, the process is temporarily terminated.

At step 750, it is determined whether or not the registration button 10a has been pressed. If an affirmative determination is made here, the process proceeds to step 760. On the other hand, if a negative determination is made, the present process is temporarily terminated. In step 760, it is determined whether or not a password has been input. If an affirmative determination is made here, the process proceeds to step 640, and thereafter, the same processing as described above is performed. On the other hand, if a negative determination is made, the process proceeds to step 680, and thereafter, the same processing as described above is performed.

As described above, in this embodiment, it is checked whether the registered license ID and the newly read license ID do not match, and if they do not match, the driving of the vehicle is prohibited. Can be prevented from being stolen. In particular,
In this embodiment, even if the key 3 is stolen, the vehicle cannot be driven unless the license IDs match, so that there is an advantage that the effect of preventing theft is high. (Embodiment 3) Next, Embodiment 3 will be described, but description of the same parts as in Embodiment 1 will be omitted.

In this embodiment, the vehicle ID and the key ID match,
In addition, driving of the vehicle is permitted only when the registered license ID matches the newly read license ID. Hereinafter, the processing in this embodiment will be described with reference to FIG.
A description will be given based on the flowchart of FIG.
