Description

The present invention relates to an electronic toll collection method for automatic toll collection on a toll road and an ETC radio control apparatus (“ETC” is a registered trademark) .

  An electronic toll collection system (ETC (Electronic Toll Collection)) that can pass without stopping at a toll booth when using toll roads has become widespread. The ETC system is a system that performs wireless communication between an ETC in-vehicle device installed in a vehicle and a roadside wireless device installed on a road, and performs automatic fee collection.

  When a vehicle with an ETC on-board device enters a toll gate at the entrance IC (Inter Change) to travel on a toll road, wireless communication is performed between the ETC on-board device and the roadside radio device installed at the toll gate, Information necessary for payment is sent and received. Then, the information on the toll gate that has passed and the date and time of passage are written in the ETC card inserted in the ETC on-vehicle device. When the vehicle leaves the toll road and enters the exit IC toll gate, the fee is settled based on the information written on the ETC card.

  The ETC system includes a tollgate ETC system and a free flow ETC system. Since the toll gate ETC system has an open / close bar for controlling the progress of the vehicle, the vehicle can be stopped by not raising the open / close bar during the abnormality process. And a fee can be collected through the receipt person at the toll gate of the exit IC. However, since the free flow ETC system does not have an open / close bar, the vehicle cannot be stopped even during abnormal processing. For this reason, charges cannot be collected at the exit IC, and charges are collected by logistical support. Logistics support is provided by charging a fee from a credit card log or the like.

By the way, as a technique for improving the convenience and reliability of the ETC system, for example, techniques described in the following patent documents are known.
Patent Document 1 is a technology that enables a general-purpose credit card to be used in an ETC system. By determining whether the credit card is usable or not while the vehicle is traveling on the main road of the toll road, the toll collection process can be performed by wireless communication at the exit of the toll road.
Patent Document 2 is a technique capable of performing an appropriate notification operation when an abnormality in writing of entrance information to an in-vehicle memory is detected. If there is a writing error, the toll collector collects the toll based on the reported information.
Patent Document 3 is a technology that can perform a work at the time of a failure or a maintenance check while continuing a vehicle traffic processing service by wireless communication on the main road of a toll road. If the working roadside machine fails, the standby roadside machine performs ETC processing instead.

  However, even if the technology shown as a publicly known example is applied to the ETC system, if an abnormal writing to the ETC card occurs, the fee will be collected as usual by the toll collector or logistic support. .

  On the other hand, with the widespread use of on-board ETC devices, taxi operators are increasingly using the ETC system. In addition, free-flow ETC systems that have lower equipment costs than tollgate ETC systems are increasing. It is a problem for a taxi-like operator who is making an immediate payment on the spot to collect charges on the spot.

  In addition, a transit service is introduced in a distance system in which a fee is determined according to a distance. The transit service is a system in which a new fee is not collected if the user returns from the toll road within a predetermined time. If this transit service is used, it becomes a travel route via many toll booths, and there is a problem that the operation load increases if the toll collection is performed by the logistic support.

  Accordingly, the present invention provides an electronic toll collection system capable of automatically collecting tolls when passing through the next toll booth even if the information on the toll booth and the date and time of passage have not been correctly written on the ETC card. It is an issue to provide.

To solve the above problems, an electronic toll collection method according to the present invention is installed in a tollgate of a toll road, ETC radio network controller in communication with the ETC vehicle-mounted device mounted on a vehicle passing through the tollgate, (A1) WCN information, which is identification information of the ETC on-board unit, transmitted from the ETC on-board unit, card identification information of an ETC card installed in the ETC on-board unit, identification information of an entrance toll gate, and billing Receiving means for receiving ETC card information including identification information of a tollgate; and (A2) ETC card information obtained by adding identification information of a toll booth where the terminal is installed to the received ETC card information.

And (A4) transmitting communication abnormality information including WCN information of the ETC on-board unit and identification information of the tollgate to a center system connected via a network, On the other hand, the communication abnormality information transmitting means for requesting to register the transmitted communication abnormality information in the communication abnormality list, and (A5) a storage means for storing the communication abnormality list transmitted from the center system,
The ETC radio control device installed at the toll gate at the toll road exit (B1) receives the WCN information and the ETC card information via the receiving means, and uses the WCN information as a search key. The communication abnormality list stored in the storage means is searched. (B2) When communication abnormality information having the same WCN information as the WCN information is extracted as a result of the search, it is included in the extracted communication abnormality information. The ETC card information received via the receiving means is corrected according to the identification information of the toll gate to be received. (B3) The received ETC card information or the received ETC card information is corrected when the received ETC card information is corrected. Toll collection using ETC card information, (B4) Charging identification information of toll gate at exit at ETC card information used for toll collection The information added as the identification information of the depository is transmitted to the ETC on-board unit via the transmission unit and written to the ETC card. (B5) The writing to the ECT card is abnormally terminated by the determination unit. If determined, the communication abnormality information including the WCN information and the identification information of the exit toll gate is transmitted to the center system via the communication abnormality information transmitting means, and the center system is transmitted to the center system. The transmission abnormality information is requested to be registered in the communication abnormality list .

  Hereinafter, a mode for carrying out the present invention (referred to as “the present embodiment”) will be described in detail with reference to the drawings. Further, in all the drawings for explaining the present embodiment, the same parts are denoted by the same reference numerals in principle, and the repeated explanation thereof is omitted.

(overall structure)
FIG. 1 is a diagram for explaining the outline of the present embodiment.
The facilities of the ETC system include a toll gate 1A (entrance IC), a toll gate 1B (exit IC), and a center system 2. The toll booth 1A and the toll booth 1B are connected to the center system 2 via the network 3.

The toll booth 1 is a facility provided for collecting toll road tolls. The toll gate 1 includes an ETC radio control device 4 and an antenna 5.
The center system 2 is a system that processes a request from the toll gate 1 and returns a processing result to the toll gate 1.
The network 3 is a communication network that transmits information between the toll gate 1 and the center system 2. In the ETC system, wired communication such as optical fiber is mainly used.

The ETC radio control device 4 is a device that exchanges information necessary for fee settlement with the center system 2 and the ETC in-vehicle device 6 and performs various processes (details will be described later).
The antenna 5 is a device that radiates radio waves by radio communication performed between the ETC radio control device 4 and the ETC vehicle-mounted device 6 into the air, or receives radio waves transmitted through the air.
The ETC vehicle-mounted device 6 exchanges information necessary for fee settlement with an ETC card (IC card) and an ETC radio control device 4 (not shown) inserted in the ETC card, and ETC card information 10 (details will be described later) on the ETC card. It is a device that reads and writes. The ETC in-vehicle device 6 stores WCN (Wireless Call Number) information that is a unique radio station identification number.

(Outline of processing)
An outline of processing performed by the ETC system will be described with reference to FIG. Details will be described later.
First, processing when entering a toll road will be described. An occupant of the vehicle 7 inserts an ETC card into the ETC onboard device 6 before entering the toll gate 1A of the entrance IC. When detecting the ETC card, the ETC on-vehicle device 6 notifies the occupant by voice or the like. Then, the vehicle 7 enters the toll gate 1A.

  When the vehicle 7 enters the communication area of the antenna 5A of the toll booth 1A, the ETC radio control device 4A and the ETC vehicle-mounted device 6 perform radio communication via the antenna 5A. In the wireless communication, the ETC in-vehicle device 6 transmits ETC card information 10 to be described later to the ETC wireless control device 4A. Further, the ETC radio control device 4A performs check processing and the like, and transmits the ETC card information 10 including the toll gate number and the passage date and time described later to the toll gate 1A to the ETC in-vehicle device 6. Then, the ETC in-vehicle device 6 writes the received ETC card information 10 in the ETC card. In addition, the ETC radio control device 4A transmits the processing result to the center system 2.

  Next, processing when leaving a toll road will be described. When the vehicle 7 enters the communication area of the antenna 5B of the toll gate 1B of the exit IC, the ETC radio control device 4B and the ETC vehicle-mounted device 6 perform radio communication via the antenna 5B. In the wireless communication, the ETC vehicle-mounted device 6 transmits the ETC card information 10 to the ETC wireless control device 4B. Further, the ETC radio control device 4B performs toll fee calculation processing and the like, and transmits the ETC card information 10 including the toll gate number of the toll gate 1B, the passage date and time, and the toll fee to the ETC in-vehicle device 6. Then, the ETC in-vehicle device 6 writes the received ETC card information 10 in the ETC card. Further, the ETC radio control device 4B transmits the processing result to the center system 2.

  However, there are cases where the ETC in-vehicle device 6 cannot write the received ETC card information 10 to the ETC card at the toll gate 1A of the entrance IC. As a cause of the abnormality, there may be a case where a communication abnormality occurs during wireless communication between the ETC wireless control device 4 and the ETC in-vehicle device 6. Since the information written in the ETC card is necessary for the toll calculation process, if the information is not written, the toll collection 1B of the exit IC cannot automatically collect the fee.

(ETC card information)
The ETC card information 10 is information written to the ETC card. The ETC card information 10 is transmitted / received via the antenna 5 by the ETC radio control device 4 and the ETC in-vehicle device 6.

  As shown in FIG. 3, the ETC card information 10 includes contract information 301, entrance information 302, barrier information 303, traffic history information 304, and usage details information 305.

The wireless communication unit 23 communicates with the ETC vehicle-mounted device 6 via the antenna 5. As a result, information is exchanged between the ETC radio control device 4 and the ETC vehicle-mounted device 6.

The ETC process check table 24 is information used when the control unit 21 performs an ETC process check. The ETC process check is a process for determining whether or not an ETC card can be used (details will be described later). The ETC processing check table 24 is transmitted from the center system 2.
The ETC processing check table 24 includes a white list that is information indicating available ETC cards, a black list that is information indicating unusable ETC cards, and the like. The white list and the black list are information relating to an individual's ability to pay, and are provided by a credit card company or the like. The ETC processing check table 24 can be divided into ETC processing check tables 24 for each type of ETC card. The types of ETC cards include, for example, classification according to an issuer and a settlement method (credit card, separate payment, etc.).

As shown in FIG. 4, the ETC process check table 24 includes an IC card IDFrom401 and an IC card IDTo402. The IC card ID From 401 is information indicating the start point of an IC card ID (identifier) that is an identifier for uniquely identifying a target IC card. The IC card ID To 402 is information indicating the end point of the target IC card ID.
For example, when FIG. 4 is a white list, focusing on the record in the second row, ETC cards corresponding to ETC card IDs “11111-222222-11111” to “11111-222222-99999” are usable. Determined.

  The charge calculation table 25 is information used when the control unit 21 performs charge calculation. The charge calculation table 25 is information including a toll according to the travel route of the vehicle 7. The fee calculation table 25 is transmitted from the center system 2.

The communication abnormality list 26 is information on the ETC vehicle-mounted device 6 that has communication abnormality at the toll gate 1 of the entrance IC. In the communication abnormality list 26, the information transmitted from the toll booth 1 in each place is collected by the center system 2, and the collected information is transmitted to the ETC radio control apparatus 4.
As shown in FIG. 5, the communication abnormality list 26 includes WCN information 501, IC card ID 502, reception source toll gate number 503, entrance information 504, barrier information 505, and traffic history information 506. Other items are stored in association with the WCN information 501.

The WCN information 501 is a radio station identification number unique to the ETC on-vehicle device 6 as described above, and can uniquely identify the ETC on-vehicle device 6. The communication abnormality list 26 is preferably arranged in ascending order of the WCN information 501 in order to shorten the processing time in the search processing described later.
The IC card ID 502 is an identifier that uniquely identifies the IC card.
The reception source toll gate number 503 is a toll gate number of a fee at which communication abnormality has occurred.

The center system 2 also has a communication abnormality list having the same configuration as the communication abnormality list 26.

  These specific functions and the like will be described in detail in the processing description to be described later.

(Processing of ETC radio controller of entrance IC)
FIG. 7 is a flowchart of processing in the ETC radio control apparatus 4.
This process is performed by the ETC radio control device 4A of the toll gate 1A of the entrance IC when the vehicle 7 enters the toll road. Processing performed by the ETC radio control apparatus 4A will be described with reference to FIGS.

  When the vehicle 7 enters the communication area of the antenna 5A of the toll gate 1A of the entrance IC, the ETC radio control device 4A and the ETC vehicle-mounted device 6 start radio communication via the antenna 5A.

In step S <b> 700, the wireless communication unit 23 receives the WCN information and the ETC card information 10 transmitted from the ETC in-vehicle device 6. Then, the control unit 21 stores the received information in the RAM.
Then, the process proceeds to step S702.

In step S702, the control unit 21 performs an ETC process check and an ETC card information creation process.
In the ETC process check, the control unit 21 performs the following check process based on the ETC card information 10 and the ETC process check table 24 received in step S700.

(1) Black List Check When the IC card ID included in the ETC card information 10 corresponds to the black list of the ETC processing check table 24, it is determined that the ETC card cannot be used.
(2) White List Check When the IC card ID included in the ETC card information 10 corresponds to the white list of the ETC processing check table 24, it is determined that the ETC card can be used.
(3) Contract check It is determined whether or not the ETC card is not illegally created.
(4) Expiration Date Check From the expiration date included in the ETC card information 10, it is determined whether or not the ETC card is within the expiration date.

The control unit 21 creates the ETC card information 10 in the ETC card information creation process. The ETC card information 10 is information written to the ETC card for use in processing such as fee calculation at the toll gate 1B of the exit IC. The ETC card information 10 is created based on the information stored in the RAM in step S700. Specifically, the toll gate number and passage date and time of the toll gate 1A are set in the entrance information 302.
Then, the process proceeds to step S704.

In step S704, the control unit 21 notifies the processing result generation communication unit 22 of the result of the processing in step S702. Then, the processing result generation communication unit 22 generates processing result information and transmits it to the center system 2. The processing result information is information including whether or not the ETC card can be used.
Then, the process proceeds to step S706.

In step S <b> 706, the control unit 21 notifies the ETC card information 10 to the wireless communication unit 23. And the radio | wireless communication part 23 transmits the said ETC card information 10 to the ETC vehicle equipment 6 via the antenna 5A. The ETC in-vehicle device 6 that has received the ETC card information 10 writes the ETC card information 10 into the ETC card inserted therein.
Then, the process proceeds to step S708.

  In step S708, the control unit 21 determines whether or not the writing to the ETC card has been normally completed. Possible causes of abnormal termination of writing to the ETC card are as follows.

First, a case where a communication abnormality occurs during wireless communication between the ETC wireless control device 4A and the ETC onboard device 6 can be considered. The communication abnormality occurs, for example, when the radio wave condition is poor due to weak or irregular reflection of radio communication radio waves, or when the processing is not in time because the vehicle 7 has passed at high speed.
Next, there may be a case where the ETC on-board device 6 or the ETC card is the cause. Specifically, a writing abnormality occurs due to a failure of the ETC on-vehicle device 6 or an ETC card not being inserted correctly.

When the writing to the ETC card is normally completed (step S708 “Yes”), the process is terminated.
If writing to the ETC card is abnormally terminated (step S708 “No”), the process proceeds to step S710.

  In step S710, the control unit 21 generates communication abnormality list data 603 shown in FIG. Further, the control unit 21 requests the center system 2 to add the communication abnormality list data 603 of the vehicle to the communication abnormality list 26 of the center system 2. This request is made by transmitting a communication abnormality list addition / deletion request message 11 shown in FIG.

FIG. 6 is a diagram for explaining an example of the communication abnormality list addition / deletion request message 11.
The communication abnormality list addition / deletion request message 11 is created when the ETC wireless control device 4 requests the center system 2 to add / delete data to the communication abnormality list 26 of the center system 2. The communication abnormality list addition / deletion request message 11 includes a transmission source toll gate number 601, a request classification 602, and communication abnormality list data 603.
The transmission source toll booth number 601 is the toll booth number of the toll booth that created and transmitted the communication abnormality list addition / deletion request message 11.

The request category 602 is information indicating whether the request is for adding information to the communication abnormality list 26 of the center system 2 or for deleting information. The request category 602 includes “addition” and “deletion”.
The communication abnormality list data 603 is information to be added to or deleted from the communication abnormality list 26 that the center system 2 has. The communication abnormality list data 603 has the same configuration as that of the communication abnormality list 26 shown in FIG. In other words, the record in the communication abnormality list 26 is a unit and includes at least one record.

  In the communication error list addition / deletion request message 11 transmitted in step S710, the toll gate number of the toll gate 1A is set in the transmission source toll gate number 601, “add” is set in the request category 602, and the ETC in-vehicle status is set in the communication error list data 603. The WCN information of the device 6, the IC card ID of the ETC card, the date and time of passing through the toll gate 1A, etc. are set.

In this way, the center system 2 receives the communication abnormality list addition / deletion request message 11 from each toll booth 1, and centrally manages the communication abnormality list data 603 in the communication abnormality list 26 that the self toll station 1 has. Data inconsistency between the communication abnormality lists 26 can be prevented.
Then, the process ends.

(Processing of ETC radio controller of exit IC)
FIG. 8 is a flowchart of processing performed by the ETC radio control apparatus 4 at the exit IC.
This process is performed by the ETC radio control device 4B of the toll gate 1B of the exit IC when the vehicle 7 leaves the toll road. With reference to FIG. 1 thru | or FIG. 6, FIG. 8, the process which ETC radio | wireless control apparatus 4B performs is demonstrated.

  When the vehicle 7 enters the communication area of the antenna 5B of the toll gate 1B of the exit IC, the ETC radio control device 4B and the ETC vehicle-mounted device 6 start radio communication via the antenna 5B.

In step S <b> 800, the wireless communication unit 23 receives the WCN information and the ETC card information 10 transmitted from the ETC onboard equipment 6. This process is the same as step S700 in FIG.
Then, the process proceeds to step S802.

  In step S802, the control unit 21 determines whether or not the WCN information received in step S800 exists in the communication abnormality list 26. Specifically, the communication abnormality list 26 is searched using the WCN information as a search key, and it is determined whether there is a record with the matching WCN information.

  The communication abnormality list 26 is received from the center system 2 as described above. The timing received from the center system 2 is preferably received whenever the communication abnormality list 26 of the center system 2 is updated. By updating the communication abnormality list 26 before the vehicle 7 passes through the toll gate 1B of the exit IC, it is possible to collect charges more reliably and automatically.

  The communication abnormality list 26 may not completely match the communication abnormality list 26 that the center system 2 has. Since the communication abnormality list possessed by the center system 2 is used for centrally managing the information of the communication abnormality list 26 possessed by each ETC radio control apparatus 4, the data stored in the communication abnormality list 26 may be selected as necessary. Good. The selection of data may be performed by the center system 2 or the ETC radio control device 4.

  For example, information on the vehicle 7 is stored in the communication abnormality list 26 of the ETC wireless control device 4 installed in the toll gate 1 where the vehicle 7 in which the communication abnormality has occurred is expected to pass depending on the road name and the traveling direction. If not, the fee cannot be settled automatically. Since it is impossible to predict which exit IC the vehicle 7 will pass through, at least the toll gate 1 with the same road name and direction of travel and installed at the toll gate 1 ahead of the toll gate 1 where the communication abnormality occurred The communication abnormality list 26 of the ETC wireless control device 4 to be stored needs to store information on the vehicle 7.

However, the communication abnormality list 26 of the ETC radio control apparatus 4 installed at the toll gate 1 where the vehicle 7 is expected not to pass does not need information on the vehicle 7.
Thus, by selecting data and reducing the number of data items stored in the communication abnormality list 26, the processing load for retrieving WCN information is reduced.

If the WCN information exists in the communication abnormality list 26 (step S802 “Yes”), the process proceeds to step S804.
If the WCN information does not exist in the communication abnormality list 26 (step S802 “No”), the process proceeds to step S806.

In step S804, the control unit 21 rewrites the ETC card information 10 received in step S800 stored in the RAM with the contents of the communication abnormality list 26. The presence of the WCN information in the communication abnormality list 26 means that a communication abnormality has occurred at the entrance IC and the writing to the ETC card could not be processed normally (step S708 “No” in FIG. 7). Therefore, the information regarding the entrance IC is not correctly stored in the ETC card information 10. Therefore, the control unit 21 cannot calculate the toll and cannot collect tolls automatically.
On the other hand, as described above (step S710 in FIG. 7), the communication abnormality list 26 includes the WCN information and the like of the ETC on-board device 6 in which writing to the ETC card could not be processed normally. Based on these pieces of information, by rewriting the ETC card information 10 stored in the RAM, it is possible to reproduce a state in which writing to the ETC card can be processed normally.
Then, the process proceeds to step S806.

In step S806, the control unit 21 performs ETC processing check, fee calculation, and ETC card information creation processing. This process is the same as step S702 in FIG.
Then, the process proceeds to step S808.

In step S808, the control unit 21 notifies the processing result generation communication unit 22 of the result of the processing in step S806. Then, the processing result generation communication unit 22 generates processing result information and transmits it to the center system 2. This process is the same as step S704 in FIG.
Then, the process proceeds to step S810.

In step S <b> 810, the control unit 21 notifies the ETC card information 10 to the wireless communication unit 23. And the radio | wireless communication part 23 transmits the said ETC card information 10 to the ETC vehicle equipment 6 via the antenna 5B. The ETC in-vehicle device 6 that has received the ETC card information 10 writes the ETC card information 10 into the ETC card inserted therein.
Then, the process proceeds to step S812.

In step S812, the control unit 21 determines whether or not the writing to the ETC card has ended normally. This process is the same as step S708 in FIG.
If the writing to the ETC card is normally completed (step S812 “Yes”), the process proceeds to step S816.
If the writing to the ETC card is abnormally terminated (step S812 “No”), the process proceeds to step S814.

  In step S814, the control unit 21 generates communication abnormality list data 603. Further, the control unit 21 requests the center system 2 to add the communication abnormality list data 603 of the vehicle to the communication abnormality list 26 of the center system 2. Since this process is similar to step S710 in FIG. 7, different points will be described.

  In the communication abnormality list addition / deletion request message 11 transmitted in step S814, the toll gate number of the toll gate 1B is set in the transmission source toll gate number 601, "added" in the request category 602, and the ETC in-vehicle state in the communication abnormality list data 603. The WCN information of the device 6, the IC card ID of the ETC card, the date and time of passing through the toll gate 1B, etc. are set.

  In this way, even when a communication abnormality occurs at the toll gate 1B of the exit IC, it is possible to collect a fee by logistic support based on the communication abnormality list 26 of the center system 2.

  In step S816, the control unit 21 deletes the information of the vehicle 7 from the communication abnormality list 26. In addition, the control unit 21 requests the center system 2 to delete the information on the vehicle 7 from the communication abnormality list 26 that the center system 2 has. This request is made by transmitting a communication abnormality list addition / deletion request message 11. The information on the vehicle 7 is information associated with the WCN information and the WCN information of the ETC vehicle-mounted device 6 installed in the vehicle 7.

In the communication abnormality list addition / deletion request message 11 transmitted in step S816, the toll gate number of the toll gate 1B is set in the transmission source toll gate number 601, “deleted” in the request classification 602, and the ETC in-vehicle state is added in the communication abnormality list data 603. The WCN information of the device 6 is set. The communication abnormality list data 603 may include the IC card ID of the ETC card, the date and time of passing through the toll gate 1A, and the like.
Then, the process ends.

(Center system processing)
FIG. 9 is a flowchart of processing in the center system 2.
This processing is performed by the center system 2 receiving a request from the ETC radio control device 4 (step S710 in FIG. 7 and steps S814 and S816 in FIG. 8).

  In step S900, the center system 2 waits for data reception from the ETC radio control apparatus 4. The data is a communication abnormality list addition / deletion request message 11. If data has been received, the process proceeds to step S902.

In step S902, the center system 2 determines whether the data received in step S900 is a request to add to the communication abnormality list 26 that the center system 2 has. That is, it is determined whether or not the request category 602 of the received communication abnormality list addition / deletion request message 11 is “addition”.
When it is a request for addition to the communication abnormality list 26 (step S902 “Yes”), the process proceeds to step S904. If it is not a request to add to the communication abnormality list 26 (step S902 “No”), the process proceeds to step S906.

In step S904, the center system 2 adds the communication abnormality list data 603 of the communication abnormality list addition / deletion request message 11 received in step S900 to the communication abnormality list 26 owned by itself.
Then, the process returns to step S900.

In step S906, the center system 2 determines whether or not the data received in step S900 is a deletion request from the communication abnormality list 26 that the center system 2 has. That is, it is determined whether or not the request category 602 of the received communication abnormality list addition / deletion request message 11 is “delete”.
If the request is for deletion from the communication abnormality list 26 (step S906 “Yes”), the process proceeds to step S908. If it is not a deletion request from the communication abnormality list 26 (step S906 “No”), the process returns to step S900.

In step S908, the center system 2 deletes the information on the vehicle 7 received in step S900 from the communication abnormality list 26 that the center system 2 has. Specifically, the communication abnormality list 26 is searched using the WCN information included in the communication abnormality list data 603 of the received communication abnormality list addition deletion request message 11 as a search key, and the record with the matching WCN information is deleted.
Then, the process returns to step S900.

(Summary)
As described above, even when the ETC card information 10 is incomplete, the ETC wireless control device 4 can automatically collect the fee by reproducing the ETC card information 10 based on the communication abnormality list 26. As a result, it is possible to reduce the operational burden of fee collection by logistic support. Moreover, since the passenger of the vehicle 7 does not have to recognize that the communication abnormality has occurred, the passenger can pass through the toll gate 1B of the exit IC without feeling uneasy about the communication abnormality.

(Other)
The above-described embodiment is suitable for carrying out the present invention, but the form of implementation is not limited to these, and various modifications can be made without departing from the scope of the present invention. Is possible.
