Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a response circuit in which information about a vehicle such as a chassis number is written in advance and which transmits the above vehicle information when an inquiry signal is received from an interrogator. The present invention relates to an electronic mark for a vehicle in which a required display content of a predetermined sign is described, and an electronic mark for a vehicle in which a response circuit is built in a windshield.

[0002]

2. Description of the Related Art Currently,
As information for identifying each vehicle from the outside, license plates attached to the front and rear of the vehicle (in the case of a motorcycle, the rear) and the inside of the windshield are generally attached every two years (only for the first 3 There is an automobile inspection mark (so-called vehicle inspection sticker) that is updated every year) and an inspection and maintenance mark (so-called regular inspection sticker) that indicates that regular inspection and maintenance have been completed. However, all of this information is visual information that can be visually determined, and it is not easy to recognize this information regarding an overrunning vehicle. Not to mention that it is very difficult at night.

A contactless information card capable of wireless communication has been conventionally known. When the information card is used in a car, the information card is aimed at the antenna of an information reader such as an interrogator. I held it over my hand and placed it on the dashboard to communicate with the interrogator. Therefore, data such as the chassis number stamped on the chassis of the automobile, the automobile registration number displayed on the license plate, the vehicle inspection expiration date, etc. is stored in these information cards, and the unique identification information of the vehicle is stored from this information card. It is also possible to detect (ID).

However, in such a usage, the information card is not completely fixed to the car, and it may be taken to another car. Therefore, the information from the information card cannot always indicate the corresponding vehicle ID, and in some cases, there is a high possibility of being misused, which is not practical.

Therefore, the present invention has been made in view of the above problems, and transmits an inquiry signal from an external interrogator instead of the conventional visual recognition information for vehicle information (vehicle number, vehicle inspection expiration date, etc.). The purpose is to enable non-contact information collection.

[0006]

Means and Actions for Solving the Problems The electronic mark for a vehicle according to the first aspect of the invention made to achieve the above object is preliminarily written with information about a vehicle such as a chassis number.
It has a response circuit that returns the vehicle information in response to a question signal from the interrogator, and the display content of a predetermined sign (hereinafter also simply referred to as the sign content) which is obligatory to be attached by law is described on the surface. It is characterized by being done.

When a question signal from an external interrogator is transmitted to the vehicle to which the vehicle electronic mark is attached, the response circuit receives the question signal and returns the previously written information about the vehicle. Therefore, it is not necessary for a person to make a direct visual judgment, and it is possible to easily recognize the vehicle information even if the vehicle is running too much.

As the content of the sign displayed on the electronic mark for a vehicle, for example, a predetermined sign content permitted to be attached to the windshield by law, such as an automobile inspection mark or an inspection and maintenance mark. If adopted, there is no problem even if it is attached to the windshield, and it is suitable for transmitting an inquiry signal from the front or the top of the vehicle. In addition, in general, if you own a vehicle for driving on a general road, it is obligatory to attach these marks, and since it is usually not removed, the information of this electronic mark is attached to the vehicle. There is almost no problem even if it is judged to be unique identification information.

Therefore, it is very effective when used for a toll collection system on a highway or a parking lot, which will be described in detail later, or for the detection of violations by police and criminal investigations. From the perspective of abuse prevention, detection of violations, and criminal investigation,
It is more effective if the electronic mark is attached by using a tamper-proof material that can be easily discerned when peeled off.

[0010] As the prescribed content of the mark on the surface of this electronic mark, it is possible to adopt if it is obligatory to affix it by law, but it is preferable to use an automobile inspection mark or an inspection and maintenance mark. Good. Because this mark is affixed to almost all vehicles, it is effective in view of the above various uses.

Further, if at least the chassis number and the vehicle inspection expiration date are written as the vehicle information to be written in advance, it is very effective not only for recognizing the vehicle ID but also for the vehicle inspection enforcement. On the other hand, a vehicle electronic mark that is a second invention made to achieve the above object,
Information about the vehicle such as a chassis number is written in advance, and a response circuit for returning the vehicle information in response to an inquiry signal from an interrogator is provided, and the response circuit is incorporated in the windshield.

When a question signal from an external interrogator is transmitted to a vehicle equipped with the electronic mark for this vehicle, a response circuit built in the windshield receives this question signal and pre-written information about the vehicle. To reply. Therefore, as in the case of attaching the electronic mark of the first invention, it is not necessary for a person to make a direct visual judgment and the vehicle information can be easily recognized even if the vehicle is overrun. .

Normally, the window glass at the time of manufacture and installation is rarely removed or replaced without permission. Therefore, it is judged that the information from the response circuit of this electronic mark is the identification information unique to the vehicle. But there is almost no problem.
Therefore, as in the case of attaching the above electronic mark, it is very effective when it is used for the charge collection system or the police to detect violations or criminal investigations.

When the response circuit is built in the windshield, the response circuit may be arranged outside the movable region of the wiper. This is because, for example, when receiving or returning by using microwaves, there is a risk of adverse effects if there is a metal, so when a metal is used for the wiper, it is necessary to have no such effect.

Further, as a driving power source for the response circuit, in addition to a battery provided in the response circuit, a device for transmitting an electromagnetic wave serving as a driving power source from the interrogator and obtaining power from the electromagnetic wave, a windshield is used. It is also possible to provide a power supply line that is arranged inside the vehicle and connects the in-vehicle power supply and the response circuit, and use the in-vehicle power supply as a drive power supply for the response circuit by the power supply line.

[0016]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic view of an electronic vehicle inspection sticker 1 which is an embodiment of the electronic mark for a vehicle of the first invention. The electronic vehicle inspection sticker 1 is roughly divided into a visual recognition information section 2a and an electronic circuit section 2b.
b is fixed with an adhesive or the like so that it cannot be easily peeled off. The visual recognition information section 2a is made of paper, for example, and has a number or the like indicating the expiration date of vehicle inspection printed thereon. A response circuit 3 that transmits and receives electronic information is incorporated in the electronic circuit section 2b.

This electronic vehicle inspection sticker 1 is shown, for example, in FIG.
As shown in FIG. 3, the front windshield 7a of the vehicle 7 is fixed with an adhesive so that it cannot be easily peeled off, or is bonded with a tamper-proof material that can be easily discriminated even if peeled off. Information is exchanged with the interrogator 8 installed above the road, for example. The interrogator 8 will be described in detail later.

The attaching position of the electronic vehicle inspection sticker 1 will be described in more detail. As shown in FIG. 2, it is desirable that the electronic vehicle inspection sticker 1 is located at the center upper portion of the windshield 7a and is just hidden by the room mirror RM when viewed from the driver's vehicle. At this position, the visibility during driving is not hindered, and since it is outside the movable range of the wiper WP (shown by the chain double-dashed line in FIG. 2), reception between the interrogator 8 and the response circuit 3 is performed. -Even when replying, the influence of the metal used for the wiper is reduced.

Next, the structure of the response circuit 3 will be described in detail with reference to FIG. The response circuit 3 is composed of an IC chip 21 that performs internal information processing, an antenna 22 that receives the inquiry signal S1 and transmits a response signal S2, and a built-in battery 23 that drives the IC chip.

Further, the IC chip 21 is a detector 21 for taking out information contained in the interrogation signal S1 received by the antenna 22.
a, a level comparator 21b that determines the reception of an inquiry signal based on the signal level from the detector 21a and supplies power to each circuit, a chassis number, a valid period of vehicle inspection, a registration number (so-called number), etc. Memory 2 for storing vehicle information
1c and a central processing unit (hereinafter, referred to as CPU) 21d that performs a transmission operation based on the information stored in the memory 21c when power is supplied from the level comparator 21b;
It is composed of a clock generator 21e for generating a clock signal for operating the U21d, and a modulator 21f for modulating the interrogation signal S1 based on an output signal from the CPU 21d and transmitting a response signal S2 from the antenna 22.

The response circuit 3 receives the interrogation signal S1 from the interrogator 8 by the antenna 22, and the level comparator 21b starts power supply to the CPU 21d and the clock generator 21e by the received signal. Then, the CPU 21
d interprets and executes the command included in the inquiry signal S1. At this time, for example, if the command requests internal storage data, the CPU 21d modulates the inquiry signal S1 with the information stored in the memory 21c and causes the antenna 22 to transmit it as a response signal S2 having internal information.

Next, the interrogator 8 which radiates a radio wave toward the response circuit 3 and extracts vehicle information will be described. The interrogator 8 transmits the interrogation signal S1 to the electronic vehicle inspection sticker 1 and receives the returned response signal S2. As shown in FIG. 4, the configuration includes a carrier oscillation circuit 11 that creates a carrier wave, a modulator 12 that superimposes information on the carrier wave to create an interrogation signal S1, a circulator 13 that separates a transmitted wave and a received wave, and an entrance / exit of an electromagnetic wave. A certain transmitting / receiving antenna 14, a demodulator 15 for extracting information from a response signal S2 which is a received wave, a signal processing unit 16 for controlling the modulator and demodulator to process information, and a necessary information of the received response signal S2. The external interface 17 communicates to an external higher-level information processing apparatus (for example, the system management computer 30 in FIG. 6).

The signal processing section 16 is composed of a CPU 16a which incorporates a program and controls communication, and a system identification information setting section 16b which sets a system identification number. The system identification information setting section 16b stores system identification information. It is composed of a PROM 16c for storing.

Next, the operation of the interrogator 8 having the above-mentioned circuit configuration will be described. Interrogation signal S1 which is a transmission wave from the interrogator 8
Is generated by modulating the carrier wave generated by the carrier oscillation circuit 11 by the modulator 12. That is, the inquiry signal S1
The data sent from the signal processing unit 16 to the modulator is superimposed on. The interrogation signal S1 thus created is sent to the circulator 13, from which the transmitting / receiving antenna 1
It is sent to 4 and emitted to the air.

When the response signal S2 is returned from the response circuit 3 of the electronic vehicle inspection sticker 1, it is received by the transmission / reception antenna 14. The response signal S2 is sent to the demodulator 15 via the circulator 13, the information contained therein is taken out, sent to the signal processing unit 16 and processed, and the taken-out information is sent to the external interface 17 if necessary. Output to. Further, the signal processing unit 16 receives a control command and various information input from the external interface 17, performs internal processing according to the contents, and sends transmission data to the modulator 32.

Using the electronic vehicle inspection sticker 1 and the interrogator 8 as described above, for example, the following system can be constructed. (1) Toll road charging system (Fig. 5) When a general car B approaches the toll gate T of the toll road TR, the car B passes through the first lane R1 and the toll collection box 2
It is necessary to stop before 7 and pay the necessary amount to the clerk P. On the other hand, the car A to which the electronic vehicle inspection sticker 1 is attached, when approaching the toll gate T of the toll road TR,
The charge settlement process is completed only by passing through the second lane R2.

The vehicle number of the vehicle is read from the electronic vehicle inspection sticker 1 by the interrogator 8 installed above the second lane R2, and based on the information registered in advance in the system management computer (not shown). This is because it is determined that this vehicle A is a vehicle that can pass through. In this case, the fee may be collected from the designated bank account at a later date. Further, by storing the read information in the database, it is possible to know the number of times of use each month, and it is also possible to provide services such as discount of the use fee to vehicles that are frequently used.

(2) Entrance / Exit Vehicle Management System at Parking Lot (FIG. 6) When a car C tries to enter the parking lot, the car C with the electronic vehicle inspection sticker 1 attached is installed above the entrance of the parking lot. The vehicle number or the like of the vehicle C can be read by the interrogator 8. The vehicle information read by the interrogator 8 is transmitted to the connected system management computer 30, and if the vehicle number of the car C is registered in advance as a customer of this parking lot,
The breaker 32 is opened based on the information read by the interrogator 8.

As a result, the car C can enter the parking lot without paying a charge. The fee collection in this case is
As in the case of the toll road in (1) above, it may be possible to withdraw from the designated bank account at a later date. In addition, by storing the read information in the database, the number of times of monthly use can be known, and services such as discounts on the usage fee can be provided to vehicles that are frequently used.

(3) Customer Sensing System (FIG. 7) When a customer who is a good customer wants to enter the car D to which the electronic vehicle inspection sticker 1 is attached at a parking lot at a department store, the customer's questioner 8 at the entrance It senses and gets vehicle information. Based on the information, the parking lot guide board 41 displays a display indicating a vacant space to provide the service, or
It is possible to provide a system in which the customer visit display is displayed on the customer visit display board 45 in the foreign-commercial room 43 so that the person in charge can immediately meet.

(4) Police enforcement of parking violations When police engage in illegally parked vehicles, they collect vehicle information (vehicle number, number, etc.) using a handy terminal with a built-in interrogator 8. By doing so, it is possible to crack down on a large number of illegally parked vehicles within a short period of time without having to leave a memory on the necessary documents with a pen, thus improving efficiency.

(5) Police enforcement of vehicle inspections When police enforce vehicle inspections, they install an interrogator 8 on or next to the road and apply radio waves to running vehicles.
From the electronic vehicle inspection sticker 1 of each vehicle, at least vehicle information of the vehicle number and the vehicle inspection expiration date is obtained. Police can use this information to detect illegal vehicles. Conventionally, it was necessary to directly judge the expiration date of the vehicle inspection mark 55 (Fig. 8) each time, but it is no longer necessary and the vehicle information can be recognized even if the vehicle is overrun. It is very effective because it can be done easily.

(6) Police Criminal Investigation When the police conduct a criminal investigation, the electronic vehicle inspection sticker 1 can be used to detect the escape vehicle. An interrogator 8 is installed at a required place in the city, information from the escape vehicle is obtained, and it is useful for tracking. In the past, it was necessary for an investigator to make a direct visual judgment based on the characteristics and number of a car, but it is no longer necessary, and it is easy to recognize the car even if it is overrun. Because it can be done, it is very effective in this respect as well.

Next, the vehicle electronic mark of the second invention will be described. FIG. 8 is a schematic configuration diagram when the response circuit 53 of the electronic mark for a vehicle of the present embodiment is built in the windshield 51, as viewed from the inside of the vehicle. The response circuit 53 is integrated with the power supply line 57 and incorporated in the windshield 51. The power supply line 57 is connected to the vehicle-mounted battery 59 through the front windshield 51.

The response circuit 53 is incorporated, for example, on the back side of the room mirror RM, in the vicinity of a place where the vehicle inspection mark 55 is generally attached, and the room mirror RM and the vehicle inspection mark 5 are installed.
It is hidden by 5 and cannot be seen from the driver's seat. Specifically, it is desirable that the upper part of the center of the windshield 51 is outside the movable range of the wiper WP (shown by the chain double-dashed line in FIG. 8). The reason for this has been described in the case of the electronic vehicle inspection sticker 1 and will not be described.

Then, the vehicle inspection mark 55 is attached, for example, at a position where the upper end of the vehicle inspection mark 55 slightly touches the response circuit 53, and a necessary display portion such as a number indicating the expiration date of the vehicle inspection mark 55 is displayed. It is more preferable that the response circuit 53 is hidden by the vehicle inspection mark 55 as well as not hidden.

The response circuit 53 has the same structure as that of the response circuit 3 used in the electronic vehicle inspection sticker 1 except that the built-in battery 23 is removed. As shown in FIG. 9, the response circuit 53 performs internal information processing with the antenna 61 for transmitting and receiving radio waves. IC chip 62 and its I
It is composed of a power supply line 57 that supplies power for driving the C chip 62, and is arranged on a transparent PET substrate 60.

When connected to another information processing device such as an IC card reader / writer, the response circuit 53 is integrated with the communication / power line 77 as shown in FIG. It is incorporated in the front windshield 51. The communication / power line 77 is connected to the information processing device 70 through the windshield 51, and the information processing device 70 is connected to the vehicle-mounted battery 59.
The information processing medium used in the information processing device 70 may be any data rewritable medium other than an IC card, such as a floppy disk or a rewritable optical disk (compact disk).

Here, the windshield of the response circuit 53 (here, the windshield 51 is taken as an example).
A method of incorporating the same into the above will be described with reference to FIG. For example, as shown in FIG. 11 (A), a method of sandwiching it with a resin portion 51b between a front glass 51a and a back glass 51c at the time of manufacturing laminated glass, or as shown in FIG. The part is molded into a concave shape from the inside (the side coming to the inside of the room), and the power supply line 57 or the power supply / communication line 77 is laid in the glass to the lower part. Then, the response circuit 53 is installed in this recess such that its electrode portion is in contact with the power supply line 57 or the power supply / communication line 77.
The glass cover 51d and the front windshield 51 are bonded with an adhesive 51e. By such a method, a windshield with a built-in response circuit in which the windshield 51 (that is, a car) and the response circuit 53 are integrated can be manufactured.

If the windshield 51 having the response circuit 53 built-in is provided in the vehicle, the toll road charging system and the entry / exit vehicle management in the parking lot are managed in the same manner as the electronic vehicle inspection sticker 1 of the first invention described above. system,
It is very effective because it can be suitably used for a customer detection system, police parking crackdowns, vehicle inspections, and criminal investigations.

Regarding charge collection in the toll road charging system shown in FIG. 5, when the IC card is connected to another information processing device 70 such as an IC card reader / writer as shown in FIG. 10, the IC card is prepaid. Assuming that the vehicle A has a function, the information that the vehicle A is determined to be a passable vehicle is transferred to the IC through the communication line 77.
Send it to the card reader, and use the IC card based on that information,
The charge settlement process ends by subtracting the prepaid frequency. If the IC card has a credit function, the IC card sends the credit number to the response circuit 53 after determining that the vehicle A is a passable vehicle, and the response circuit 53 to the interrogator 8. By communicating the number, the charge settlement process can be processed by credit.

In the case of the entrance / exit vehicle management system in the parking lot shown in FIG. 6 as well, by using the IC card reader / writer together with the system for reading the credit number with the interrogator 8, the parking fee is credited. Processing becomes possible. In FIG. 8, the response circuit 53
Is generally placed near the place where the vehicle inspection mark 55 is attached, but may be placed in the upper corner where the inspected and maintained mark 56 is attached, for example, in FIG. Even in this position,
It is outside the movable range of the wiper WP (two-dot chain line in FIG. 8).

Further, in the windshield having the response circuit 53 built-in, the vehicle often travels forward and the interrogator 8 is used.
In view of the above, it is considered that it will be mainly used in the front windshield 51 as described above, but in terms of technical idea, it is not denied that it is used in the rear windshield or the side windshield. However, in the case of a movable side window,
When all of them are stored in the side door, it is expected that the influence of the metal used for the door on reception and reply between the interrogator 8 and the response circuit 53 will increase. It may be better to avoid it when considering applications such as enforcement. Further, the response circuit 53 in FIG. 9 is not limited to PET as long as it is transparent, and other resin or glass may be used.

Next, the window glass 5 with a built-in response circuit described above.
Another embodiment related to No. 1 will be described. As shown in FIG. 12, the electrical configuration of this embodiment includes an antenna 101, an information processor 104, a shield wire 107 connecting the antenna 101 and the information processor 104, a power supply 106 and an actuator 105. The information processor 104 includes an RF processing IC 102 and a reader / writer (hereinafter simply referred to as R / W).
Also expressed. ) 103, and exchanges data alternately.

The R / W 103 is an IC card R / W, a magnetic card reader, or the like. The shield wire 107 is
In order to prevent the influence of noise between the antenna 101 and the RF processing IC 102, it is necessary to use a shielded wire instead of an ordinary wire. The actuator 105 is, for example, a seat moving motor or a door mirror angle adjusting motor for changing the driving position.

Specifically, this antenna 101 is shown in FIG.
As shown in 3, do not obstruct the driver's view,
In the front windshield 111 of the car on which the vehicle inspection mark 55 is pasted, on the back side of the room mirror RM, or
The information processing device 104, which is embedded in the windshield 111 of the vehicle at the position where the periodic inspection certificate 56 is attached and is embedded in the dashboard of the vehicle, is the shield wire that has crawled around the windshield 111. They are connected by 107.

As shown in FIG. 14, the information processing device 1
In the RF processing IC 102 in 04, there are two types of memories 113. First, information specific to that car, for example,
Regarding the registration number data and the vehicle inspection expiration date, the data cannot be changed or erased by turning the power on / off or ultraviolet rays, but it can be electrically rewritten.
The PROM 114 is used. On the other hand, personal information, for example, the ID number of a certain membership sports club, the registration number in the toll road charging system as shown in FIG. 5, or the registration number of the provided parking lot in the parking lot management system as shown in FIG. The data such as “SRAM 115” is reset (erased) by turning the power on / off.
With the above EE, data cannot be easily changed or erased by turning the power on / off, but electrically rewritable.
The PROM 114 is used. Also, the information processor 10
A numeric keyboard is attached to the personal computer 4, and personal information can be retrieved from the EEPROM 114 by inputting a personal identification number.

The operation of this embodiment will be described. RF
When the vehicle is registered, data unique to the vehicle, such as registration number data and vehicle inspection expiration date, is input to the memory in the partial processing IC 102 and the EEPROM 114.
The input method is R / W using an IC card or a magnetic card.
You may input from 103, or by using the antenna 101 embedded in the windshield 111,
You may enter it wirelessly. This data cannot be rewritten by an individual, and can only be changed by the Land Transport Office when inspecting or re-registering.

At the start of use of the car, the driver inserts an IC card or a magnetic card into the information processor 104 (R / W 103) on the dashboard and stores the personal information in the memory 11.
3 into the EEPROM 114. At this time, the personal identification number is registered. The input personal data is stored regardless of whether the power is on / off or the engine is on / off, and is not erased. After that, the personal information that has been input can be recalled at any time by inputting a personal identification number, so that it is not necessary to carry the card around one by one, and it is not necessary to re-input the personal information each time the vehicle is driven.

In the actual operation, when the car engine is started, of the information input to the EEPROM 114,
The information peculiar to the vehicle, that is, the data of the registration number and the vehicle inspection expiration date is unconditionally input to the SRAM 115. When the personal identification number is input, the personal information corresponding to the personal identification number is also uploaded. In this state, for example, when passing in front of the interrogator 8 in FIG. 5 or FIG. 6, the SRAM
The information input to 115 is read by the interrogator 8 through the antenna 101 of the car, and communication is performed.

Then, the received information is input to a host computer (not shown) on the system side, and necessary processing is performed. At this time, if necessary, the information sent from the interrogator 8 is received by the antenna 101 of the car and the information processor 104
It is also possible to write the data in the EEPROM 114.

When the engine is turned off when leaving the vehicle, the power source 106 is cut off, and the RF processing IC 10
Among the memories in 2, the information written in the SRAM 115 is reset. However, the contents written in the EEPROM 114 are not erased in this state, and the contents are retained.

In the other embodiment, the RF processing IC1 is used.
Although 02 is installed in the information processor 104 on the dashboard of the car, it may be embedded in the windshield 111 as in the case of the antenna 101. In this case, the shield wire 107 is unnecessary. Further, although the personal information is called by the personal identification number, any other method such as a magnetic card, an IC card, fingerprint collation or the like can be used as long as the ID can be confirmed.

Further, although the antenna 101 is embedded in the front window glass 111 in the above embodiment, it may be attached to the inside of the front window glass 111.
Further, the information processing device 104 may be provided with a display unit showing the communication content. The R / W 103 may be an optical card as well as an IC card and a magnetic card.

[0055]

As described above, an inquiry signal from an external interrogator is sent to a vehicle to which the electronic mark for a vehicle of the first invention is attached or a vehicle equipped with the electronic mark for a vehicle of the second invention. When sent, the response circuit receives this interrogation signal and returns pre-written information about the vehicle, so it is not necessary for the person to make a direct visual judgment and to recognize the vehicle information even if the vehicle is overrun. Easy to do. And, if the specified content of the sign permitted by law is adopted as the content of the sign displayed on the electronic mark, there is no problem even if it is affixed to the windshield, and it is usually not removed. Therefore, there is almost no problem even if it is determined that the identification information is unique to the vehicle.

Therefore, according to the first and second aspects of the present invention, the information about the vehicle such as the chassis number and the vehicle inspection expiration date can be contactlessly collected by an interrogator instead of the conventional visual information. It is very effective when used for toll collection systems in parking lots or for police violations and criminal investigations.
