Description

  The present invention relates to an in-vehicle device capable of realizing a billing process such as a toll and a product purchase price.

  In recent years, ETC systems have become widespread. However, since the current ETC system is a type in which a contact type IC card is inserted into an in-vehicle device, a contact failure between the IC card and the in-vehicle device occurs or the driver forgets to insert the IC card. As a result, an event has occurred in which the vehicle cannot normally pass through the entrance gate and the exit gate of the ETC system.

  Therefore, in order to solve such a problem, the applicant of the present application copies the card information from the IC card to the in-vehicle device in advance, and uses the copied card information when passing through the gate. An invention was first filed that allows the passage of the gate without the need (see Prior Application 1).

  [Prior Application 1] Japanese Patent Application No. 2006-313377

  In the invention filed by the above prior application, it is configured to be able to store the card information of a plurality of IC cards in the in-vehicle device, but if a plurality of card information is stored in the in-vehicle device, the user I would like to perform billing using the most appropriate card information.

  The present invention has been made in view of such a demand, and provides an in-vehicle apparatus that realizes an accounting process using appropriate card information in an in-vehicle apparatus that stores a plurality of card information that can be used for the accounting process. With the goal.

  The in-vehicle device according to claim 1, which has been made to solve the above-described problem, stores a plurality of billing destination identification information that is information that can identify a billing destination (for example, a credit card account, a deposit account, an individual, a corporation, etc.). A billing destination specifying information storage unit, a selection unit that selects billing destination specifying information stored in the billing destination specifying information storage unit based on conditions set in advance in association with the billing destination specifying information, and a selection unit that selects The billing destination specifying information is read from the billing destination specifying information storage means and used, and charging processing realizing means for realizing charging processing by communicating with the roadside device is provided.

  According to such an in-vehicle device, by setting an appropriate condition in advance, billing destination specifying information based on the condition is selected. Then, the billing process is performed using the selected billing destination specifying information. That is, billing processing is performed using appropriate billing destination identification information.

  Here, the conditions may be fixedly set in advance by the manufacturer of the in-vehicle device, but may be set arbitrarily by the user of the in-vehicle device. That is, a condition setting unit for setting a condition when the charging destination specifying information stored in the charging destination specifying information storage unit is selected in association with the charging destination specifying information based on a user operation, and a condition setting unit The vehicle-mounted device is configured to include a condition storage unit for storing the condition set by the control unit, and the selection unit is stored in the billing destination specifying information storage unit based on the condition stored in the condition storage unit The billing destination specifying information may be selected (claim 2).

With such an in-vehicle device, the user can arbitrarily set conditions, so that billing processing is realized using billing destination specifying information according to the user's wishes.
In addition, as one specific example of the condition, it is preferable that the object of the charging process is limited (claim 3). For example, there is a condition that “the object of the charging process is a toll road operated by a XX road operator”, a condition that “the object of the charging process is a XX product”, and the like.

If this is the case, it is possible to selectively use the billing destination identification information according to the billing processing target, and the convenience for the user is improved.
In addition, as a specific example of the condition, a discount amount for billing processing may be used (claim 4). For example, there are a condition that “there is a discount”, a condition that “a discount amount is 500 yen or more”, and the like.

If this is the case, it is possible to use the billing destination specifying information in accordance with the discount amount of the billing process, and the convenience for the user is improved.
By the way, as a toll road charge calculation method, there are a distance-based charge calculation method charged based on the use distance and a uniform charge calculation method charged uniformly regardless of the use distance. Here, in the case of the distance calculation method, there is a system in which billing destination specifying information (for example, a card ID) is transmitted to a roadside device at an entrance gate to determine the validity of the billing destination specifying information. However, if the billing destination specifying information to be used is selected as described above, the billing destination specifying information may not be determined when entering the entrance gate. For example, there is a case where the presence / absence of discount is determined according to the usage distance, or the presence / absence of discount is determined according to the passage time of the exit gate.

  Accordingly, when the vehicle equipped with the in-vehicle device passes through the entrance gate of the toll road of the distance type, the charging processing realizing means charges all the charging destination specifying information that can be used for the charging processing of the toll road. The information may be read from the destination specific information storage means and transmitted to the roadside device. If this is the case, the roadside device can determine the validity of the billing destination identification information. Then, the selection means selects one charging destination specifying information based on a condition set in advance in association with the charging destination specifying information from among the charging destination specifying information whose validity is recognized by the roadside device. The processing realizing means reads the billing destination specifying information selected by the selecting means from the billing destination specifying information storage means when the vehicle equipped with the in-vehicle device passes through the exit gate of the toll road of the distance type. It is good to transmit (Claim 5).

  In this case, the charging process is not attempted by invalid charging destination identification information, and the charging process can be normally completed more reliably.

  Embodiments to which the present invention is applied will be described below with reference to the drawings. The embodiment of the present invention is not limited to the following embodiment, and can take various forms as long as they belong to the technical scope of the present invention.

[Description of operation]
Next, the operation of the ETC system 10 will be described.
(1) Registration of card information for in-vehicle device to portable terminal 30 First, processing for registering card information for in-vehicle device will be described with reference to the explanatory diagram of FIG.

  When the control unit 37 of the mobile terminal 30 accepts a setup AP acquisition request command from the user via the HMI 33 (specifically, an operation button), the control unit 37 sets up to the mobile terminal site server 55 via the wireless public line network 51. A request for acquisition of a business AP is made (S50).

Receiving this request, the mobile terminal site server 55 transmits the designated setup AP to the mobile terminal 30 via the wireless public network 51 (S55).
The control unit 37 of the portable terminal 30 that has received the setup AP starts execution of the setup AP, and requests ETC area creation information from the area issuing server 57 via the wireless public line network 51 (S60). The “ETC area creation information” here is information for setting a storage area (area) for specific card information in the storage unit 36 of the mobile terminal 30.

  Upon receiving the request for ETC area creation information, the area issuing server 57 generates information (ETC area creation information) necessary for creating an ETC area in the mobile terminal 30. Then, the generated information is transmitted to the portable terminal 30 via the wireless public line network 51 (S65).

The control unit 37 of the mobile terminal 30 that has received the ETC area creation information generates an ETC area in the storage unit 36 using the received ETC area creation information.
Thereafter, when the control unit 37 of the mobile terminal 30 receives an instruction from the user via the HMI 33 (specifically, an operation button) to acquire in-vehicle device card information to be stored in the in-vehicle device 20, It communicates with the in-vehicle device 20 via the contact communication interface 35, acquires in-vehicle device specific information (management number, type registration number, vehicle number, etc.) from the in-vehicle device 20 and stores it in the ETC area of the storage unit 36 (S70). ). Then, the card information for the in-vehicle device is requested to the card center server 59 via the wireless public line network 51 (S75).

  Upon receiving this request, the card center server 59 generates in-vehicle device card information, encrypts the generated in-vehicle device card information, and transmits the encrypted in-vehicle device card information to the portable terminal 30 via the wireless public network 51 (S80).

The control unit 37 of the mobile terminal 30 that has received the in-vehicle device card information stores the received in-vehicle device card information in the ETC area of the storage unit 36.
The in-vehicle device card information is registered in the portable terminal 30 by such a procedure. Note that a plurality of types of in-vehicle device card information can be stored in the ETC area of the storage unit 36 of the mobile terminal 30 by the same procedure as described above.

(2) Registration of in-vehicle device card information to in-vehicle device 20 Next, in the processing procedure described above, a command to acquire in-vehicle device card information is carried via the HMI 33 (specifically, an operation button). Details of processing after the terminal 30 receives (mainly S70 to S80) and processing for registering the card information for the in-vehicle device in the in-vehicle device 20 will be described with reference to the ladder chart of FIG.

  When the control unit 37 of the portable terminal 30 receives an instruction from the user via the HMI 33 (specifically, an operation button) to acquire in-vehicle device card information to be stored in the in-vehicle device 20, non-contact communication The in-vehicle device specific information (management number, format registration number, vehicle number, etc.) is requested to the in-vehicle device 20 via the interface 35 (S105).

The control unit 27 of the in-vehicle device 20 that has received the request transmits the in-vehicle device specific information to the mobile terminal 30 via the non-contact communication interface 25 (S110).
The control unit 37 of the mobile terminal 30 that has received the in-vehicle device specific information stores the received in-vehicle device specific information in the ETC area of the storage unit 36, and further, the card center server 59 via the wireless antenna 31 and the public communication unit 32. Requesting the card information for the in-vehicle device (S115). The information to be transmitted is not only the information meaning the request, but also the in-vehicle device specific information stored in the ETC area of the storage unit 36 and the card information for the mobile terminal stored in the storage unit 36 in advance. 59. Note that the mobile terminal card information is card information used when the mobile terminal 30 performs billing processing. When the user of the portable terminal 30 holds the portable terminal 30 over the dedicated terminal at a convenience store, a restaurant, or the like, the card information for the portable terminal is read out by the dedicated terminal and billing processing is executed.

  The card center server 59 that has received a request for card information for in-vehicle devices from the portable terminal 30 determines whether the received card information for portable terminal is valid (S120). Specifically, it is determined whether or not the mobile terminal card information is properly issued card information by referring to a database in which data related to the mobile terminal card information is stored. If it is determined by this determination that the mobile terminal card information is valid, the in-vehicle device card information is generated (S125). This in-vehicle device card information is information that is scheduled to be stored in the in-vehicle device 20, and is information that is read from the in-vehicle device 20 and used for billing as necessary.

When the card center server 59 generates the card information for the in-vehicle device, the card center server 59 transmits the generated card information for the in-vehicle device to the mobile terminal 30 (S130).
The control unit 37 of the mobile terminal 30 that has received the in-vehicle device card information causes the HMI 33 (specifically, a liquid crystal display) to display that the attribute of the received in-vehicle device card information is input. And the attribute of the card information for vehicle equipment is received from a user via HMI33 (operation button) (S140).

  Here, the attribute of the card information for in-vehicle devices will be described. In addition, since the attribute of the card information for in-vehicle devices accepted by the user is finally stored in the storage unit 26 of the in-vehicle device 20 as attribute information, the in-vehicle device is used using the attribute information table in which the attribute information is stored. The attribute of card information will be described.

  FIG. 5A is a schematic diagram of an attribute information table. As shown in FIG. 5 (a), each record in the attribute information table corresponds to the attribute of the card information for the in-vehicle device, and the card information ID for the in-vehicle device, the use permitted business operator ID, and the discount application only. It consists of designation, priority, and default designation. The in-vehicle device card information ID is an ID for specifying the in-vehicle device card information, and thus, one in-vehicle device card information is specified. The usage-permitted business operator ID is an ID for identifying a road management business operator that is permitted by the user to use the on-vehicle device card information specified by the on-vehicle device card information ID. That is, the in-vehicle device card information specified by the in-vehicle device card information ID is used only for the toll road operated by the road management business operator specified by the use-permitted business operator ID ( However, in the case of default designation, it is also used for payment of toll roads operated by businesses that are not designated as licensed business operator IDs). The exclusive designation at the time of applying the discount indicates whether or not to use the card information for the in-vehicle device specified by the card information ID for the in-vehicle device only when there is a service for paying the toll road (only when there is a discount). Flag. The priority is information used when selecting card information for in-vehicle devices when there is a plurality of in-vehicle device card information that can be used and there is no difference in conditions such as ID and special application at discount application. Note that the smaller the number set as the priority, the higher the priority. The default designation is a flag for specifying the in-vehicle device card information that is assigned when there is no in-vehicle device card information that can be used in consideration of the use-permitted provider ID and the conditions for exclusive use at the time of discount application. In this flag, one record is always on (“◯” in FIG. 5A) among the records constituting the attribute information table.

  Returning to FIG. 4, when the control unit 37 of the mobile terminal 30 receives the attribute of the card information for in-vehicle device from the user, the card information for in-vehicle device received from the card center server 59 and the in-vehicle device input by the user. The attribute information of the card information is transmitted to the in-vehicle device 20 through the non-contact communication interface 35 (S145).

The control unit 27 of the in-vehicle device 20 that has received the in-vehicle device card information and the attribute information stores the received in-vehicle device card information and the attribute information in the storage unit 26 (S150).
When the received in-vehicle device card information and its attribute information are stored in the storage unit 26, the control unit 27 of the in-vehicle device 20 sends a notification that the storage is completed (registration completion notification) to the non-contact communication interface 25. To the portable terminal 30 (S155).

  The control unit 37 of the mobile terminal 30 that has received the registration completion notification displays on the HMI 33 (specifically, a liquid crystal display) that the registration of the card information for the in-vehicle device to the in-vehicle device 20 is completed (S160).

(3) Processing at the time of passing through a gate with a flat fee system Next, the ladder chart of FIG. 6 is used for charging processing at a gate when a vehicle equipped with the vehicle-mounted device 20 passes through a toll road of a flat fee system. I will explain. In addition, the roadside apparatus 53 in the description of this section may be installed at the entrance of the toll road, may be installed at the exit, or may be installed in the middle of the traveling road.

  The vehicle-mounted device 20 receives a BST (Beacon Service Table) from the roadside device 53 when entering the communicable area of the roadside device 53 (S205). When receiving the BST from the roadside device 53 via the wireless antenna 21 and the DSRC unit 22, the control unit 27 of the onboard device 20 determines whether or not the onboard device card information that can be charged by the roadside device 53 is stored. If stored, a VST (Vehicle Service Table) is transmitted to the roadside device 53 via the DSRC unit 22 and the wireless antenna 21 (S210).

  Subsequently, mutual authentication is executed between the in-vehicle device 20 and the roadside device 53 (S215). A known method is used as the mutual authentication method. And if the result of this mutual authentication is normal, the transmission request | requirement of the card information for vehicle equipment will be transmitted from the roadside apparatus 53 with respect to the vehicle equipment 20 (S220). Then, the control unit 27 of the in-vehicle device 20 selects one in-vehicle device card information from the plurality of in-vehicle device card information stored in the storage unit 26 by performing a selection process A described later ( S225).

  Subsequently, the control unit 27 of the in-vehicle device 20 transmits the in-vehicle device card information selected in S225 to the roadside device 53 via the DSRC unit 22 and the wireless antenna 21 (S230).

  The roadside device 53 that has received the in-vehicle device card information from the in-vehicle device 20 executes a specific billing process (S235). For example, the card information for in-vehicle devices, the gate passage time, the vehicle type information, etc. are transmitted to the information center, and a request is made to deduct the toll from a predetermined account.

Subsequently, the roadside device 53 transmits the result of the billing process (normal completion / non-completion, billing amount, etc.) to the in-vehicle device 20 (S240).
The control unit 27 of the in-vehicle device 20 that has received the result of the charging process from the roadside device 53 via the wireless antenna 21 and the DSRC unit 22 sends the result of the charging process to the user via the HMI 23 (specifically, LED or speaker). Inform. For example, an LED indicating normal completion is emitted, or a sound such as “charging for a uniform toll of 650 yen has been successfully performed” is output from a speaker.

A series of processes as described above are executed at the timing when the gate passes.
(4) Selection Process A Next, the selection process A (S225) executed by the control unit 27 of the in-vehicle device 20 in the above-described process at the time of passing through the gate of the flat fee method will be described with reference to the flowchart of FIG. explain.

  When starting the execution of the selection process A, the control unit 27 of the in-vehicle device 20 first narrows down the in-vehicle device card information from the viewpoint of the road operator (S305). Specifically, with reference to the use-permitted carrier ID in the attribute information table stored in the storage unit 26, the vehicle-mounted vehicle that is permitted to be used by the carrier managing the roadside device 53 that is currently communicating. Identify the device card. If there is a plurality of in-vehicle device card information that is permitted, a plurality of pieces are specified.

  Subsequently, the control unit 27 of the in-vehicle device 20 branches the process depending on the number of narrowed in-vehicle device card information (S310). If there is no permitted in-vehicle device card information (S310: 0), the process proceeds to S315, and if the number of in-vehicle device card information narrowed down is one (S310: 1) The process proceeds to S320, and when the number of narrowed in-vehicle device card information is 2 or more (S310: 2 or more), the process proceeds to S325.

  In S <b> 315 that proceeds when there is no permitted in-vehicle device card information, the default in-vehicle device card information is selected from the in-vehicle device card information stored in the storage unit 26. That is, with reference to the attribute information table, the record whose default designation is on (“◯” in FIG. 5A) is specified, and the in-vehicle device card information corresponding to the in-vehicle device card information ID of the specified record. Is selected from the card information for in-vehicle devices stored in the storage unit 26. And the control part 27 of the vehicle-mounted apparatus 20 complete | finishes this process (selection process A), and performs the step (S230-) after the selection process A in the process at the time of gate passage of a flat fee system.

  In step S320, which is performed when the number of narrowed in-vehicle device card information is one, the in-vehicle device card information is selected. And the control part 27 of the vehicle-mounted apparatus 20 complete | finishes this process (selection process A), and performs the step (S230-) after the selection process A in the process at the time of gate passage of a flat fee system.

  Further, in S325, which proceeds when the number of narrowed in-vehicle device card information is 2 or more, it is determined whether or not a discount service is currently available. Specifically, information indicating a time zone during which the discount service can be received is stored in the storage unit 26, and determination is made based on the information. For example, when the time zone based on the information stored in the storage unit 26 is 7:00 to 10:00, it is determined that the discount service can be received if the current time is 8:00. As a result of this determination, if it is determined that the discount service can be received (S325: Yes), the process proceeds to S330, and if it is determined that the discount service cannot be received (S325: No), the process proceeds to S355. To migrate.

  In step S330, which is performed when it is determined that the discount service can be received, it is determined whether or not the in-vehicle device card information narrowed down in step S305 includes a dedicated item for discount application. Specifically, a record corresponding to each on-vehicle device card information narrowed down in S305 is read from the attribute information table, and the determination is made by examining the dedicated designation at the time of discount application of the read record. As a result of this determination, if it is determined that there is a discount-only card information narrowed down in S305 (S330: Yes), the process proceeds to S335, and the in-vehicle device narrowed down in S305. When it is determined that there is no card information exclusive for discount application (S330: No), the process proceeds to S355.

  In step S335 that is performed when it is determined that there is in-vehicle device card information dedicated for discount application, it is determined whether or not the in-vehicle device card information is one. If it is determined that there is one (S335: Yes), the process proceeds to S340, and if it is determined that there are two or more (S335: No), the process proceeds to S345.

  In S340 which proceeds when it is determined that there is one, the control unit 27 of the in-vehicle device 20 selects the card information for the in-vehicle device and ends this processing (selection processing A). Steps (S330 and subsequent steps) after the selection process A in this process are executed.

  On the other hand, in S345 which proceeds when it is determined that there are two or more instead of one, each discount amount is calculated when each on-vehicle device card information is used. And the card information for in-vehicle devices with the largest discount amount is selected (S350). Thereafter, the control unit 27 of the in-vehicle device 20 ends the present process (selection process A), and executes the steps after the selection process A (from S230) in the process at the time of passing through the gate of the flat fee method.

  In S355 that proceeds when a negative determination is made in S325 and a negative determination is made in S330, the vehicle device card information with the highest priority is selected from the vehicle device card information narrowed down in S305. This priority is acquired with reference to the attribute information table. And the control part 27 of the vehicle-mounted apparatus 20 complete | finishes this process (selection process A), and performs the step (S230-) after the selection process A in the process at the time of gate passage of a flat fee system.

  On the other hand, in S720, which proceeds when it is determined that the number of on-vehicle device card information determined to be usable is 2 or more, it is determined whether a discount service is currently available. Specifically, the determination is made based on information indicating a time zone in which the discount service can be received and a distance calculation table stored in the storage unit 26. Here, the distance calculation table will be described with reference to the table explanatory diagram of FIG. The distance calculation table is a table that can specify the road distance between both gates by designating the entrance number that is the number of the entrance gate and the exit number that is the number of the exit gate. For example, the distance between the entrance gate with the entrance number “2” and the exit gate with the exit number “4” is 55 km.

  Returning to FIG. 11, when it is determined that the discount service can be received by the determination in S720 (S720: Yes), the process proceeds to S725, and when it is determined that the discount service cannot be received (S720: No), the process proceeds to S750.

  In step S725 that is performed when it is determined that the discount service can be received, it is determined whether or not there is a dedicated card for discount application in the card information for in-vehicle devices determined to be usable at the entrance gate. Specifically, the record corresponding to each on-vehicle device card information determined to be usable at the entrance gate is read from the attribute information table, and the determination is made by examining the special designation at the time of discount application of the read record. As a result of this determination, if it is determined that there is a card for in-vehicle device that has been determined to be usable at the entrance gate, that is exclusive for discount application (S725: Yes), the process proceeds to S730, and the entrance gate If it is determined that no in-vehicle device card information determined to be usable in step 1 is available for discount application (S725: No), the process proceeds to S750.

  In S730, which proceeds when it is determined that there is card information for in-vehicle devices dedicated to discount application, it is determined whether there is only one in-vehicle device card information. If it is determined that the number is one (S730: Yes), the process proceeds to S735. If it is determined that the number is not one (S730: No), the process proceeds to S740.

  In S735, which proceeds when it is determined that there is only one, the in-vehicle device card information dedicated to the discount application is selected, and this processing (selection processing C) ends. And the control part 27 of the vehicle-mounted apparatus 20 performs the step (S630-) after the selection process C in the process at the time of the exit gate passage of a distance type.

  On the other hand, in S740, which proceeds when it is determined that there are two or more instead of one, the respective discount amounts are calculated when using the in-vehicle device card information. And the card information for in-vehicle devices with the largest discount amount is selected (S745), and this processing (selection processing B) is ended. Thereafter, the control unit 27 of the in-vehicle device 20 executes the steps after the selection process B (S630 to S630) in the process at the time of passing the exit gate in the distance type.

  In S750 that proceeds when a negative determination is made in S720 and a negative determination in S725, the card information for the in-vehicle device with the highest priority is selected from the in-vehicle device card information determined to be usable at the entrance gate. select. This priority is acquired with reference to the attribute information table. And the control part 27 of the vehicle-mounted apparatus 20 complete | finishes this process (selection process C), and performs the step (S630-) after the selection process B in the process at the time of the exit gate passage of a distance type.
