Description

  The present invention relates to display of billing information when an electronic fee collection system (Electronic Toll Collection System: hereinafter referred to as ETC) is used.

  In order to smoothly enter and exit tollgates on expressways and toll roads, ETC using wireless communication has become widespread. In addition, smart interchanges (hereinafter abbreviated as smart ICs) that have an ETC gate in the service area (SA) such as an expressway and a parking area (PA) and can enter and exit from the ETC gate have become widespread.

  When a vehicle equipped with an ETC on-vehicle device passes through the ETC gate, ETC charging information is transmitted from the ETC roadside device installed at the ETC gate to the ETC on-vehicle device. When the ETC in-vehicle device is connected to an in-vehicle device having a navigation function or the like, ETC charging information is displayed on the display of the in-vehicle device, and the user can be notified of the toll fee.

  In addition to displaying ETC billing information on the display of the in-vehicle device, as shown in Patent Document 1, information on the use of toll roads was printed based on information about payment received from the traffic management device, and toll roads were used There is a technique that can confirm the usage details immediately after.

JP 2003-30697 A

  In some toll road systems for toll roads such as expressways, the toll is higher if the towed vehicle (hereinafter referred to as a towed vehicle) is towed than when it is not towed. The presence / absence of the towed vehicle is automatically determined at the ETC toll gate, and charging is performed in consideration of the towed vehicle. However, even in such a case, the information on the presence / absence of the towed vehicle is not transmitted to the in-vehicle device side, and the user is informed whether or not the charged amount is based on the presence / absence of the towed vehicle. I could not.

  Even when there is a towed vehicle, the toll differs depending on the number of axes of the towed vehicle. That is, if the number of axes of the towed vehicle is two, the toll fee is higher than when the number of axes is one. However, even if the number of axes of the towed vehicle is 2, if there is a distance between the axes (the distance L between the axes shown in FIG. 13) is less than 1 m, there is a fee system that treats as one axis. In such a fee structure, even if the number of axes can be detected by a sensor or the like at an ETC toll gate, it is difficult to accurately measure the distance between the axes. A handling fee may be collected. In this case, since the information regarding the towed vehicle is not transmitted to the in-vehicle device side, the user cannot know whether the fee is for one axis or two axes. At a later date, if you find yourself overcharged and try to request a fee correction, it is difficult to prove it. Therefore, it is desirable to notify the presence / absence of the towed vehicle at the toll gate and the number of the shafts when the towed vehicle is present.

  The present invention solves such a conventional problem, and an object thereof is to provide an electronic device, a billing display program, and a billing display method capable of presenting a vehicle type corresponding to billing information.

  An electronic device according to the present invention includes an acquisition unit that acquires charging information for a toll road, a storage unit that stores charging information defined based on a vehicle type and a travel section of the host vehicle, the charging information, and the charging information. Comparison means, determination means for determining the vehicle type corresponding to the charging information based on the comparison result of the comparison means, and display means for displaying the vehicle type determined by the determination means together with the charging information.

  Preferably, when the billing information by the comparison unit matches the fee information of the vehicle type of the host vehicle, the determination unit determines that the billing information is a model of the host vehicle that does not have a towed vehicle. Preferably, when the billing information by the comparing means is different from the charge information of the vehicle type of the own vehicle, the determination means causes the comparison means to compare the charge information with the charge information of the vehicle type one rank higher than the own vehicle. When the billing information and the charge information of the vehicle type one rank higher match, the determination means determines that the axle is a vehicle type having one towed vehicle. Preferably, when the billing information obtained by the comparing means is different from the charge information of the vehicle type one rank higher than the own vehicle, the determination means informs the comparison means to the charge information and the charge information of the second rank vehicle type of the own vehicle. When the billing information matches the price information of the two-ranked vehicle type, the determination means determines that the axle is a vehicle type having a towed vehicle with two axes. Preferably, when the charging information by the comparing means does not match any charge information, the determining means determines that the vehicle type is unknown. Preferably, the electronic device further includes storage means for storing travel history information of the own vehicle, and the display means displays the vehicle type determined by the determination means together when displaying the travel history information.

  The charge display program according to the present invention is executed by an electronic device having storage means and display means for storing charge information defined based on the vehicle type and travel section of the host vehicle, and acquires charge information on toll roads A step of comparing the charging information with the fee information, a step of determining a vehicle type corresponding to the charging information based on a comparison result of the comparing step, and the determined vehicle type together with the charging information Displaying.

  The charge display method according to the present invention is in an electronic device having a storage means and a display means for storing charge information defined on the basis of the vehicle type and travel section of the host vehicle, and acquiring the charge information of the toll road Comparing the charging information with the charging information, determining a vehicle type corresponding to the charging information based on a comparison result of the comparing step, and displaying the determined vehicle type together with the charging information Steps.

  According to the present invention, the vehicle type corresponding to the billing information is determined based on the comparison result between the billing information and the own vehicle fee information, and the determined vehicle type is displayed together with the billing information. The vehicle type corresponding to the billing information (for example, the presence or absence of a towed vehicle or, if there is a towed vehicle, a one-axis or two-axis vehicle) can be recognized. As a result, it is possible to easily make a correction request for an erroneous billing request or the like.

  The preferred embodiment of the present invention relates to display of billing information when the host vehicle passes through an ETC roadside device, and in particular, automatically determines a vehicle type corresponding to the billing information and displays the determined vehicle type together with the billing information. . The vehicle type here refers to the vehicle type of the vehicle (for example, light vehicle, ordinary vehicle, medium-sized vehicle, large vehicle, extra large vehicle), presence or absence of towed vehicle, and number of towed vehicle axles if there is towed vehicle (1-axis or 2-axis). For example, as shown in FIG. 13 (A), when the vehicle M1 is towing a towed vehicle M2 having one axle A, the number of vehicles M1 is 2 as shown in FIG. 13 (B). When the towed vehicle M2 having two axles A1 and A2 is towed, it is 1 axis if the inter-axis distance L between the axles A1 and A2 is less than 1 meter, and 2 if it is 1 meter or more.

  FIG. 1 is a diagram showing a configuration example of a billing information display system according to the first embodiment of the present invention. The billing information display system 1 includes an in-vehicle device 100 mounted on a vehicle, an ETC in-vehicle device 200, and an ETC roadside device (ETC gate) 300. The ETC vehicle-mounted device 200 may be connected to the vehicle-mounted device 100 or may be built in the vehicle-mounted device 100. When the ETC vehicle-mounted device 200 passes through the ETC roadside device 300, the ETC vehicle-mounted device 200 performs two-way communication with the ETC roadside device 300, and performs a charge settlement process corresponding to the travel section of the toll road. At this time, the ETC in-vehicle device 200 receives the billing information from the ETC roadside device 300, and the received billing information is output by voice or video.

  FIG. 2 is a block diagram illustrating a configuration example of the in-vehicle device according to the first embodiment. The in-vehicle device 100 according to the first embodiment includes an input unit 110, a position information calculation unit 120, a navigation unit 130, a display unit 140, an audio output unit 150, a storage unit 160, a communication unit 170, and an external I / F (interface). The unit 180 and the control unit 190 are configured. However, this configuration is an example.

  The input unit 110 receives an instruction from the user through an input key device, a voice input recognition device, a touch panel, and the like, and provides this to the control unit 190. The position information calculation unit 120 calculates the current location of the host vehicle based on GPS signals transmitted from GPS satellites and sensor outputs of gyro sensors and acceleration sensors mounted on the vehicle. For example, the navigation unit 130 searches for a route from the current location to the destination and guides the searched route, or causes the display unit 140 to display a road map around the vehicle position. The display unit 140 includes a liquid crystal display and other display devices. For example, the display unit 140 displays an image of a road map generated by the navigation unit 130, displays charging information received from the ETC roadside device 300, and the like.

  The storage unit 160 can store programs executed by the control unit 190, application software, a map database, and the like. Furthermore, the present embodiment includes a toll database that enables toll tolls for toll roads to be calculated from the vehicle type and travel section of the vehicle.

  FIG. 3 shows a vehicle type and a toll for a certain travel section X. The vehicle types are light cars, ordinary cars, medium-sized cars, large-sized cars, and extra-large cars, and the toll charges are shown when these car types do not have towed vehicles. For example, the toll when traveling in the travel section X with a light vehicle is ¥ 3,610, and for a regular vehicle is ¥ 4,470. The toll fee when there is a towed vehicle is as follows. When a light vehicle is towing a one-axis towed vehicle, the toll will be 4,470 yen, which is the same amount as a one-class model. Furthermore, when a light vehicle is towing a two-axis towed vehicle, the toll is ¥ 5,330, which is the same as the toll of a car of two classes. Similarly, if a normal vehicle is towing a 1-axis towed vehicle, it will be a toll for a medium-sized vehicle, and if it is towing a 2-axis towed vehicle, it will be a toll for a large vehicle. . It is not necessary for the toll database to have the “1-axis towing class” and “2-axis toll class” data shown in FIG. 3, and the toll database has a 1-axis or 2-axis towed vehicle according to the algorithm described above. It is sufficient to calculate the toll. In addition, the toll database includes tolls for not only the travel section X but also for all travel sections for each vehicle type, and is specified based on billing information or entry / exit information from the ETC roadside device 300 or the ETC on-board unit 200 The toll according to the section can be obtained from the toll database.

  The communication unit 170 enables wireless data communication with an external network or an external device. As shown in FIG. 4, the communication unit 170 accesses external sites such as a toll distribution site 172, a map data distribution site 174, and a road traffic information distribution site 176 via the network NW, and acquires various types of information. Can do. When the toll distribution site 172 distributes part or all of the toll database, the storage unit 160 does not necessarily need to store the entire toll database.

  The external I / F unit 180 enables connection with the ETC on-vehicle device 200. Data communicated between the ETC vehicle-mounted device 200 and the ETC roadside device 300 is provided to the vehicle-mounted device 100 via the external I / F unit 180, or data of the vehicle-mounted device 100 is provided to the ETC roadside device 300. For example, the charging information received by the ETC on-board device 200 from the ETC roadside device 300 is provided to the in-vehicle device 100, or the location information of the ETC roadside device into which the vehicle has entered or exited from the ETC on-vehicle device 200 is provided to the on-vehicle device 100. Can be done. Further, information on the own vehicle set in the ETC in-vehicle device 200 (for example, the vehicle type information of the own vehicle, that is, the type of light vehicle, ordinary vehicle, medium-sized vehicle, large-sized vehicle, or extra-large vehicle) is provided to the in-vehicle device 200. .

  The control unit 190 includes a microprocessor and a microcontroller, and controls each unit by executing a program or the like stored in the ROM / RAM or the storage unit 160. In a preferred embodiment, a billing information display program for controlling the display of billing information received from the ETC on-board unit 200 when the vehicle passes the ETC roadside device 300 is included.

  FIG. 5 is a diagram illustrating a functional configuration example of the billing information display program of the present embodiment. The billing information display program 400 includes a billing information acquisition unit 410, a setting information acquisition unit 420, a fee information acquisition unit 430, a fee information comparison unit 440, a vehicle type determination unit 450, and a billing display image generation unit 460.

  The billing information acquisition unit 410 acquires billing information provided from the ETC on-board unit 200 when the vehicle passes through the ETC roadside device 300 that is an exit of the toll gate. The billing information is billing information for the travel section transmitted from the ETC roadside device 300 when a vehicle using the ETC passes the toll road toll gate. The billing information can include, for example, a section in which the vehicle has traveled (a point where the vehicle gets off from a point where the toll road is entered) and a charge for the travel section.

  The setting information acquisition unit 420 acquires setting information related to the own vehicle set in the ETC on-vehicle device 200. The setting information includes, for example, vehicle type information of the own vehicle. However, when the setting information is once acquired from the ETC on-board device 200 and stored in the storage unit 160, the setting information can be acquired from the storage unit 160. The vehicle type information included in the setting information is, for example, the type of vehicle such as a light vehicle, a normal vehicle, a medium-sized vehicle, a large vehicle, and an extra large vehicle.

  The toll information acquisition unit 430 acquires the corresponding toll information from the toll database owned by the own vehicle based on the vehicle type information and the travel section acquired by the vehicle type information acquisition unit 420. The traveling section may be specified from the billing information, or may be specified from the position information transmitted from the ETC onboard device 200 when the own vehicle passes the ETC roadside device 300. For example, when the vehicle type of the host vehicle is a normal vehicle and the vehicle travels in the travel section X, the charge information of “¥ 4,470” is acquired from the toll database shown in FIG.

  The charge information comparison unit 440 compares the charge information acquired by the charge information acquisition unit 410 with the charge information acquired by the charge information acquisition unit 430. Specifically, the amount of billing information is compared with the amount of fee information. The comparison result of the charge information comparison unit 440 is provided to the vehicle type determination unit 450.

  When the charge information and the charge information indicate a matching result, the vehicle type determination unit 450 determines that the vehicle type corresponding to the charge information is the vehicle type of the host vehicle that does not have the towed vehicle. When the charge information and the charge information indicate a comparison result that does not match, the vehicle type determination unit 450 causes the charge information acquisition unit 430 to acquire the charge information of the vehicle type one class above the host vehicle. That is, when the vehicle type of the host vehicle is a normal vehicle, the charge information of the medium-sized vehicle is acquired, and the charge information comparison unit 440 compares the charge information of the vehicle type one class above with the charging information. The vehicle type determination unit 450 determines that the vehicle type corresponding to the charging information is a vehicle type having a one-axis towed vehicle when the charge information of the vehicle type on one class and the charging information match. If the charge information of the vehicle type on the first class does not match the billing information, the vehicle type determination unit 450 causes the charge information acquisition unit 430 to acquire the charge information of the vehicle type on the second class of the host vehicle. That is, when the vehicle type of the host vehicle is a normal vehicle, the charge information of the large vehicle is acquired, and the charge information comparison unit 440 compares the charge information of the two types of vehicles with the charging information. The vehicle type determination unit 450 determines that the vehicle type corresponding to the charging information is a vehicle type having a two-axis towed vehicle when the charge information and the charging information of the vehicle types on the two classes match. If the charge information for the vehicle type on the second class does not match the billing information, the vehicle type determination unit 450 determines that the vehicle type is unknown. The charge display image generation unit 460 generates a charge display image including the determined charge and vehicle type information based on the determination result of the vehicle type determination unit 450 and causes the display unit 140 to display the charge display image.

  Next, the ETC vehicle-mounted device shown in FIG. 1 will be described. FIG. 6 is a block diagram illustrating a functional configuration example of the ETC on-vehicle device. The ETC on-vehicle device 200 includes a setting unit 210 for setting setting information such as identification information of the own vehicle, a vehicle type of the own vehicle, and payment information for automatically paying a fee, and setting information set by the setting unit 210 is used as an ETC roadside device. Setting information transmission unit 220 that transmits to 300, charging information reception unit 230 that receives charging information from ETC roadside device 300 when leaving a toll road, and transmits the charging information and setting information set by setting unit 210 to in-vehicle device 300 An accounting / setting information transmission unit 240 is included.

  FIG. 7 is a block diagram illustrating a functional configuration example of the ETC roadside device. The ETC roadside device 300 includes a setting information receiving unit 310 that receives setting information from the ETC on-board device 200, a charging information generating unit 320 that generates charging information for a travel section based on the vehicle type of the host vehicle included in the setting information, A charging information transmission unit 330 is included that transmits the charging information to the ETC on-board unit 200. When creating the billing information, it is necessary to specify the point where the host vehicle entered the toll road, but the point can be received from the ETC on-board unit 200, or from the ETC roadside machine when the host vehicle entered The position information may be transferred together with the setting information to the ETC roadside machine when the host vehicle leaves.

  Next, the operation of the billing information display system of this embodiment will be described. FIG. 8 is an operation flow of the billing information display system. When the vehicle exits the toll road, data communication is performed between the ETC roadside device 300 and the ETC on-board device 200, and setting information necessary for automatic fee settlement is transmitted from the ETC on-board device 200 to the ETC 300. Billing information is created by the creation unit 320 (S100), and this is transmitted to the ETC on-board unit 200. Next, the ETC vehicle-mounted device 200 transmits billing information and necessary setting information to the vehicle-mounted device 100 (S102).

  When the in-vehicle device 100 receives the billing information / setting information (S104), the in-vehicle device 100 then refers to the billing information / setting information to identify the travel section and the vehicle type of the host vehicle, and refers to the toll database owned by the host vehicle. Then, charge information defined by the travel section and the vehicle type is acquired (S106). Next, the acquired fee information and billing information are compared (S108), and the comparison result is provided to the vehicle type determination unit 450. When the fee information and the billing information match, the vehicle type determination unit 450 determines that the vehicle type of the billing information is the vehicle type of the host vehicle without the towed vehicle (S110). On the other hand, when the rates do not match, the rate information acquisition unit 430 acquires the rate information of the vehicle type that is one rank higher than the own vehicle (S112), and the rate information comparison unit 440 the rate of the vehicle type that is one rank higher The information and billing information are compared (S114), and the determination result is provided to the vehicle type determination unit 450. If they match, the vehicle type determination unit 450 determines that the vehicle type of the billing information is a vehicle type having a one-axis towed vehicle (S116). On the other hand, if the rates do not match, the rate information acquisition unit 430 acquires the rate information of the car model that is two ranks higher than the own vehicle (S118), and the fee information comparison unit 440 The information and billing information are compared (S120), and the determination result is provided to the vehicle type determination unit 450. If they match, the vehicle type determination unit 450 determines that the vehicle type of the billing information is a vehicle type having a 2-axis towed vehicle (S122). On the other hand, if the charges do not match, the vehicle type determination unit 450 determines that the vehicle type of the billing information is unknown (S124).

  The determination result of the vehicle type determination unit 450 is provided to the charge display image generation unit 460, and the charge display image generation unit 460 generates an image including the determined vehicle type together with the charge information, and displays the image on the display unit 140 ( S126). As a result, when the user passes the ETC roadside device 300, the user can recognize the billing information and the vehicle type corresponding to the billing information. If the towed vehicle is overcharged, the user requests a correction. It becomes easy. In particular, when the towed vehicle has two axes but the distance between the axes is less than 1 m, it is useful for a correction request when the fee for the towed vehicle with two axes is mistakenly collected. That is, as described in the conventional problem, since the inter-axis distance of the towed vehicle cannot be accurately measured in the ETC roadside machine, the place that should be determined as a 1-axis towed vehicle originally is When it is determined that the vehicle is a towed vehicle and the fee is excessively charged, the user can confirm the vehicle type corresponding to the billing information on the spot and apply for correction on the spot.

  FIG. 9A is a display example when it is determined in step S114 of FIG. 8 that the charges match and it is determined that the vehicle has a single-axis towed vehicle, and FIG. 9B shows that the charges match in S120. It is a display example when it determines with having a towed vehicle of 2 axes. The vehicle type display 142 includes a vehicle type 142A in which the host vehicle is set and information 142B of the towed vehicle, and the towed vehicle information 142B indicates that the towed vehicle has one or two axes. If the charges match in step S108 and it is determined that there is no towed vehicle, nothing is displayed or no towed vehicle is displayed in the towed vehicle information 142B. If the charges do not match in step S120, the vehicle type display 142 displays vehicle type unknown.

  Next, a second embodiment will be described. In the second embodiment, the billing information created in the first embodiment is stored in the storage unit 160 together with the travel history, and the billing information is displayed together when the travel history is displayed later.

  FIG. 10 is a diagram illustrating a functional configuration example of the billing information display program according to the second embodiment. The billing information display program 400A according to the second embodiment includes a history information acquisition unit 470 and a history display image generation unit 480 in addition to the functions shown in the first embodiment.

  The billing information when passing through the ETC roadside device 200 is stored in the storage unit 160 together with the travel history, and the history information acquisition unit 470 acquires the history information from the storage unit 160. The history information includes the ETC gate passage date and time, travel section, billing information, and vehicle type information corresponding to the billing information. The history information acquisition unit 470 is executed, for example, when there is a request for display of history information from the user. Based on the history information acquired by the history information acquisition unit 470, the history display image generation unit 480 generates a travel history image including the identification of the vehicle type corresponding to the billing information and causes the display unit 140 to display it.

  FIG. 11 shows an example of history information stored in the storage unit 160, and FIG. 12 shows an example of history information read from the storage unit 160. As shown in FIG. 12, in the second embodiment, when the travel history is displayed, the vehicle type corresponding to the billing information can be displayed together.
