Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a technique for calculating a fee to be paid at a toll booth on a toll road when the vehicle travels on a toll road and informing the user of the same.
[0002]
[Prior art]
Conventionally, on toll roads that pay tolls such as expressways, users often have to pay for tolls because they prepare tolls by looking at the toll table after arriving at the toll gate, especially for traffic volume There was a problem of traffic congestion around the interchange (hereinafter abbreviated as IC) where there are many tollgates.
[0003]
The fee system includes a pay-as-you-go system that pays a fee at the IC exit according to the usage section of the toll road, and a flat fee system that pays a batch at the IC entrance regardless of the usage section. And since the toll system differs depending on the toll road, it is difficult for the user to determine whether the payment is prepaid or postpaid, so it takes time to prepare the toll, or how much toll fee to pay when transferring to multiple expressways There was a problem that it was not possible to immediately grasp whether it was good or the total fee.
[0004]
Therefore, when a toll road such as an expressway is included in the guide route, the charge for the use section of the toll road is calculated on the basis of the charge data indicating the name of each interway and the toll between each interway, and the navigation to guide in advance There is an apparatus (for example, refer to Patent Document 1).
[0005]
[Patent Document 1]
JP-A-10-141982 ([0021], [0022], FIG. 7).
[0006]
[Problems to be solved by the invention]
However, in addition to the above fee system, there is a discount fee system on toll roads. That is, when you pass through a certain section, you get a transit ticket, a discount ticket, a pass ticket, etc. (hereinafter collectively referred to as a discount ticket), and the next section presents these discount tickets at the toll booth. This is a discounted fee system where the toll for the section is discounted or payment is not required. However, the navigation apparatus described in Patent Document 1 does not consider a discount fee system. For this reason, there is a problem in that the toll to be guided is calculated based on the fee data corresponding to the pay-as-you-go system or the uniform toll system, so that a toll that is different from the discounted toll that is actually paid is introduced.
[0007]
The present invention has been made in view of the above problems, and an object of the present invention is to provide a vehicular fee guidance device that enables guidance suitable for a fee system when traveling on a toll road.

Depending on the accuracy, a part of the above may be used, and further, a steering rotation sensor, a wheel sensor of each rolling wheel, or the like may be used. The position detector 1 can detect the current position of the vehicle and can acquire road information on the basis of the map data stored in the map data storage device 6. Then, similarly to the conventional vehicle-mounted navigation device, it is possible to display the display device 9 with a vehicle current position mark indicating the current position of the vehicle.
[0027]
The map data storage device 6 (corresponding to the storage means in the present invention) is map matching data for improving position detection accuracy, gate facility data, map data, facility data, and a fee table (fee data and discount fee data). ) Are displayed, and data necessary for navigation is stored. The gate facility data is composed of gate facility types, discount-related information, and the like as information on ICs, ticket offices, ticket offices, toll gates, etc. that are gate facilities on toll roads. The map data is a map formed by connecting a plurality of nodes such as intersections with links, and for each link, a unique number (link ID) for identifying the link and the length of the link are set. The link information is composed of data of the link length, the X and Y coordinates of the start and end of the link, the road width of the link, and the road type (indicating road information such as a toll road). The structure of the map data using the link information and the like is the same as the conventional one. When searching for a route, a cost is added for each node or link depending on the link length, road type, etc., and finally the departure place ( Among the routes from the current position) to the destination, the route with the lowest cost is selected as the optimum route.
[0028]
The fee table stored in advance for fee calculation includes fee data and discount fee data. The toll data here is information on tolls when using toll roads with a pay-per-use system or a uniform toll system, and indicates the charges corresponding to every use section and each use section. The discount fee data is information on tolls when discounts are applied to tolls when using discounted toll roads. As a storage medium of the map data storage device 6, a CD-ROM (or DVD-ROM) is generally used because of the amount of data, but a medium such as a memory card or a hard disk may be used. .
[0029]
The operation switch group 7 is composed of, for example, a touch switch or a mechanical switch integrated with the display device 9, a remote control terminal, and the like. Various information such as destination setting for route search can be entered.
[0030]
The control circuit 8 (corresponding to the calculation means and determination means of the present invention) has a computer means, and has a well-known CPU, ROM, RAM, I / O and these configurations inside. A connecting bus line is provided. The control circuit 8 performs various control processes in the in-vehicle navigation device such as route search and map display in consideration of the fee, and the processed information is notified by the display device 9.
[0031]
The display device 9 mainly uses a liquid crystal display device, but a CRT display device, an organic EL display, or the like can also be used, and has a function corresponding to the notification means and the gate notification means in the present invention. Then, the map data acquired from the map data storage device 6, the vehicle current position mark generated based on the current position information from the position detector 1, and additional data such as a guide route displayed on the map are further included. It can be displayed overlaid. In addition, you may add the speaker (not shown) which performs an audio | voice guidance as an alerting | reporting means and a gate alerting | reporting means in this invention.
[0032]
The external memory 10 is composed of a writable non-volatile storage medium such as an HDD or a flash ROM, and the calculated toll and the corresponding data for associating the calculated toll with the usage section are turned off. Stores data that must not be erased. Note that the charge table for charge calculation stored in the map data storage device 6 may be stored in the external memory 10.
[0033]
In the above-described configuration, the in-vehicle navigation device searches for a route from the starting point set by the user by the switch group 7 or the current position acquired from the position detector 1 to the destination set by the switch group 7. If a toll road is included on the searched route, a toll is calculated in advance based on information stored in the map data storage device 6 and the display device 9 etc. Broadcast information about usage.
[0034]
Hereinafter, charge calculation processing performed for guiding the charge in such a navigation apparatus will be described with reference to FIGS. 2 and 3.
[0035]
In FIG. 2, when a start point (current position) and a destination are set by the switch group 7 in step (hereinafter abbreviated as “S”) 100, a route search is performed in S101. At this time, the route search is performed by performing cost calculation by a known Dijkstra method or the like. Then, it is determined whether or not a gate facility exists in the route based on the map data stored in the map data storage device 6 in S102. If it is determined that there is no gate facility in the route (S102: No), it is not necessary to calculate a fee, and the fee calculation process is terminated.
[0036]
If it is determined in S102 that there is a gate facility in the route (S102: Yes), the gate facility scheduled to pass first is a discount-capable gate facility based on the gate facility data stored in the map data storage device 6 It is determined whether or not (S103). If it is determined that it is not a discount-compatible gate facility (S103: No), the process proceeds to S104. On the other hand, if it is determined that the gate facility is compatible with discount (S103: Yes), it is determined in S108 whether or not the searched route passes through the discount adaptive section. That is, even if a discount ticket (corresponding to the discount qualification in the present invention) is acquired, even if it does not pass through a toll booth where the discount ticket can be used on the route, or even a toll booth where the discount ticket can be used In the case of not passing through a gate facility where discount coupons can be obtained in advance. And when it does not pass the gate which can acquire a discount ticket, or when it does not pass the gate which can use it even if it acquires a discount ticket, it determines with not passing an adaptation area. When it is determined not to pass through the discount adaptive section (S108: No), the process proceeds to S104, but when it is determined to pass through the discount adaptive section (S108: Yes), the discount handling fee processing (S108: After that, the process proceeds to S107.
[0037]
In S104, it is determined based on the gate facility data stored in the map data storage device 6 whether or not the type of the gate facility is a ticket issuer. If it is determined that it is a ticketing office (S104: Yes), in order to obtain a use section, a toll gate that passes next on the route is searched based on the type information of the gate facility (S105). That is, the toll gate corresponding to the gate facility determined to be the ticketing office is searched for on the route (S105). Thereafter, the process proceeds to S106.
[0038]
On the other hand, if it is determined in S104 that the ticket is not issued (S104: No), it is determined whether the toll gate is a flat fee system or a toll gate (S110). That is, it is determined based on the gate facility data stored in the map data storage device 6 as in S102 and S104 whether or not it is a prepaid toll gate. When it is determined that the toll gate is a flat fee system or a toll gate (S110: Yes), the process proceeds to S106. In the case of the toll collection here, the use section is obtained by searching for a toll gate on the route in the same manner as in S105. If it is determined that the toll gate is not a uniform toll gate or a toll gate (S110: No), it is determined that it is a ticket gate, etc., and the process proceeds to S107.
[0039]
In S <b> 106, the toll for the toll road to be used is obtained based on the toll data stored in the external memory 10, and the obtained toll and the corresponding data are stored in the external memory 10. In S107, it is determined whether or not all gate facilities in the route have been searched. If it is determined that all gate facilities in the route have been searched (S107: Yes), the charge calculation process is terminated. On the other hand, if it is determined that all the gate facilities in the route have not been searched (S107: No), in S111, a gate facility that is close to the next departure point on the route and has not been processed is searched and searched. For the completed gate facility, the process proceeds to S103 and the above process is repeated.
[0040]
Next, the discount handling fee processing performed in S109 when the searched gate is a discount toll gate (S103: Yes) and the route passes through the discount adaptive section (S108: Yes) will be described with reference to FIG. To do.
[0041]
In FIG. 3, first, in S200, it is determined whether or not the target gate facility is a ticketing office. If it is determined that it is a ticketing office (S200: Yes), a toll gate that passes next on the route is searched based on the type information of the gate facility in S201 in order to obtain a use section. In other words, the corresponding toll gate is searched for on the route to the gate facility determined to be the ticketing office, and then the process proceeds to S202. On the other hand, if it is determined that it is not a ticketing place (S200: No), it is determined whether or not it is a uniform toll gate or a collection toll gate (S203). That is, as in S110 of FIG. 2, it is determined whether or not it is a prepaid toll gate. When it is determined that the toll gate is a flat fee system or a toll gate (S203: Yes), the process proceeds to S202. Here, in the case of the collection toll gate, the use section is obtained by searching for the toll gate on the route in the same manner as S110 in FIG. When it is determined that the toll gate is not a flat fee system or a toll gate (S203: No), it is determined to be a ticket checking station or the like, and the discount handling fee processing ends.
[0042]
In S 202, the toll is calculated based on the discount fee data stored in the external memory 10, and the calculated toll and the corresponding data are stored in the external memory 10. Then, after obtaining the toll considering the discount, the discount handling fee processing is terminated.
[0043]
For the toll considering the discount, the toll is obtained from the first discount-compatible toll gate that passes after the gate facility where discount tickets on the route can be obtained. Therefore, even in the case of a route that gets on and off a plurality of toll roads, the toll road use section can be obtained in the same manner as the section actually traveling, and an accurate toll can be calculated. In other words, it is possible to prevent the fee from being erroneously calculated as a use section up to another toll gate even though there is a discount toll gate in front. Further, when any of a plurality of discount forms can be applied, such as when using a transit ticket or when using a round ticket, the discount charge is calculated in consideration of the discount form that provides the lowest overall price.
[0044]
As described above, in the vehicle navigation device of the present embodiment, when a searched road includes a toll road, not only the toll in the conventional pay-per-use system and the uniform toll system, but also the toll by the discounted toll system. Can also be calculated.
[0045]
Further, in this vehicle navigation device, not only the calculated toll but also the indication that discounts are applied and that the acquisition and use of discount coupons are encouraged by a notification means such as the display device 9 at a predetermined timing by the user. To inform. The calculated toll is the operation switch when the route search is completed (at the end of the fee calculation process), when it is determined that the map data and the current position are in front of a predetermined distance (for example, 50 m) from the toll gate, or by the user When notification is requested by the operation of the county 7, the information corresponding to the use section is notified from the external memory 10.
[0046]
And if you need to get a discount ticket at the gate facility or submit a discount ticket at the toll gate to adapt the discount, you can use the transfer ticket at the toll gate. "Take a transit ticket," and so on, such as "You can get a discount ticket" or "You can use a transit ticket." Notifications regarding the acquisition and use of discount coupons can be made before the toll booth at a predetermined distance (for example, 50 meters before), including the type of discount coupons, and it is possible to prevent forgetting to take discount coupons or forgetting to deliver them. Become.
[0047]
Furthermore, if there is a section where discounts can be applied in the searched route, after the route search or when the toll is notified, there is a discount compatible section in the set route or the notified toll is the discounted fee. Notify that there is.
[0048]
The processing flow and notification timing have been conceptually described above, but some specific examples will be described for a more appropriate understanding.
[0049]
(Specific example 1)
FIG. 4 a is a diagram showing a part of a route 20 that uses the A highway 21 of a metered rate system from the A gate 22 to the D gate 23. Route search is performed in the charge calculation process (FIG. 2: S101), and when the route 20 is selected, it is determined that a gate facility exists in the route 20 (FIG. 2: S102: Yes). If it is determined that the A gate 22 is not a discount-compatible toll gate (FIG. 2: S103: No), it is determined that the A gate 22 is a ticket office because it is the IC entrance to the A highway (FIG. 2: S104: Yes), the corresponding toll gate is searched (FIG. 2: S105). In the route 20, the A highway 21 is used up to the D gate 23, so the D gate 23 corresponds to the toll gate corresponding to the A gate 22. As a result, in S106 of FIG. 2, based on the charge data 25 shown in FIG. 4B, the charge 28 to the D gate 23 as the IC exit 27 for the A gate 22 which is the IC entrance 26 is calculated as 900 yen, and the calculation result 900 yen Is stored in the external memory 10 together with the response data A-D. Here, the charge data 25 stored in the external memory 10 shows an example of a toll corresponding to the use from the IC entrance to the IC exit of the toll road, and the form is not limited to FIG. 4b.
[0050]
After the fee calculation processing is completed, the route is displayed on the display device 9 and the toll (900 yen) is associated with the section from the A gate 22 to the D gate 23 based on the correspondence data stored in the external memory 10. Is displayed in a form that can be confirmed. When the vehicle is actually traveling, it detects the approach to the front 50m of the D gate 23 based on the map data stored in the map data storage device 6 and the position information from the position detection device 1, and again The toll 900 yen stored in the external memory 10 is notified on the display device 9 or the like. The thick line in FIG. 4a represents a highway, and the thin line represents a general road.
[0051]
(Specific example 2)
FIG. 5 a is a diagram showing a part of a route 30 that uses the B highway 31 of the flat fee system from the A gate 32 to the exit 33. Here, the thick line represents a highway as in FIG. 4a, and the thin line represents a general road. Route search is performed in the charge calculation process (FIG. 2: S101), and when the route 30 is selected, it is determined that a gate facility exists in the route 30 (FIG. 2: S102: Yes). And it is determined that the A gate 32 is not a discount-compatible toll gate (FIG. 2: S103: No), and the A gate 32 is the IC entrance to the B highway, but the B highway is a flat fee system. It is determined that the ticket is not issued (FIG. 2: S104: No). As a result, it is determined in S110 of FIG. 2 that the A gate 32 is a uniform toll gate, and the fee 37 for the A gate 32 of the toll gate 36 is calculated as 500 yen based on the fee data 35 shown in FIG. Is remembered.
[0052]
When the fee calculation processing is completed, the route is displayed on the display device 9 and the fee (500 yen) is displayed in a form in which the correspondence with the A gate 32 can be confirmed based on the correspondence data stored in the external memory 10. When the vehicle is actually running, it detects the approach of 50 meters before the A gate 32 based on the map data stored in the map data storage device 6 and the position information from the position detection device 1, and again The display device 9 or the like notifies the toll 500 yen stored in the external memory 10. Here, as in the first specific example, the form of the fee data 35 is not limited to FIG. 5b.
[0053]
(Specific example 3)
FIG. 6A is a diagram showing a part of a route 40 for transferring from the A highway 40 (a metered rate system) to the B expressway 42 (a uniform fee system) from the A gate 43 to the exit 46. Route search is performed in the charge calculation process (FIG. 2: S101), and when the route 40 is selected, it is determined that a gate facility exists in the route 40 (FIG. 2: S102: Yes). First, the usage fee from the A gate 43 to the C gate 44 is calculated by processing in the same manner as in the pay-per-use system of the first specific example, and the fee of 800 yen is stored in the external memory 10 together with the corresponding data AC.
[0054]
Next, in S107 of FIG. 2, it is determined whether or not the search for all gate facilities on the route 40 has been completed. Since no processing is performed for the H gate 45, it is determined that the search for all gate facilities is not completed (FIG. 2: S107: No), and the H gate 45 is searched as the next gate facility in S111. Based on the gate facility data in the map data storage device 6, the H gate 45 is determined to be a discount-compatible toll gate (FIG. 2: S103: Yes). In S108, it is determined whether or not the discount compatible section is passed. Since it can be determined from the gate facility data that the transfer ticket can be acquired by the C gate 44 passing before the H gate 45, the discount compatible section is determined. It is determined to pass (FIG. 2: S108: Yes). Then, discount handling fee processing (FIG. 2: S109) is performed on the H gate 45.
[0055]
In the discount handling fee processing (FIG. 2: S109), the H gate 45 is the IC entrance to the B highway 42, but since the B highway 42 is a flat fee system, it is determined that it is not a ticketing office ( FIG. 3: S200: No). As a result, it is determined in S203 of FIG. 3 that the H gate 45 is a uniform toll gate, and based on the discount compatible fee data 47 shown in FIG. The charge 50 for the gate 45 is calculated as 0 yen. The calculated discount fee is added to the previously calculated 800 yen toll from the A gate 43 to the C gate 44, and the calculated 800 yen together with the corresponding data A-H is the total toll, and the toll is 0 yen. It is stored in the external memory 10 together with the corresponding data H gate 45 as a discount fee.
[0056]
When the fee calculation processing is completed, the route is displayed on the display device 9 and the fee (800 yen) is associated with the section from the A gate 43 to the C gate 44 based on the correspondence data stored in the external memory 10. A discount fee (0 yen) is displayed corresponding to the H gate 45. Further, it may be displayed that the transit ticket is applied and that the transit ticket is acquired at the C gate 44 and the transit ticket is presented at the H gate 45. Then, when the vehicle is actually traveling, if the approach to the front 50 m of the C gate 44 is detected based on the map data stored in the map data storage device 6 and the position information from the position detection device 1, Notify the toll 800 yen from the A gate 43 to the C gate 44 stored in the external memory 10 on the display device 9 and the like, and indicate that a transfer ticket such as “Please obtain a transit ticket” is available. Inform. After that, when an approach to 50 meters before the H gate 45 is detected, the transit fee corresponding to the H gate 45 stored in the external memory 10 is used, and a connection ticket such as “You can use a transit ticket. Notify that the ticket can be used and notify the toll to be paid when using the transit ticket.
[0057]
Thus, the calculated toll notifies the amount to be paid before a predetermined distance from the toll booth that pays the toll. Further, the fact that the discount ticket can be obtained is notified before a predetermined distance of the gate facility where the discount ticket can be obtained, and the fact that the discount ticket can be used is notified before the predetermined distance of the gate facility where the discount ticket can be used. Here, the discount-compatible fee data 47 shows an example of a toll when using a discount ticket at a toll gate on a toll road, and the form is not limited to FIG. 6b. Also in FIG. 6a, a thick line represents an expressway and a thin line represents a general road.
[0058]
As described above, when a route using a toll road is selected by the in-vehicle navigation device according to the present embodiment, it is possible to provide fee guidance in consideration of various fee systems in consideration of discounts, advance payment / post-payment, and the like. Therefore, it is possible to provide more accurate fee guidance and to make payment smoothly by informing the user in advance.
[0059]
In this embodiment,
When a toll road was included in the searched route, the usage fee was guided, but it was detected that the vehicle was running on a toll road taxiway, and the same procedure as above was performed. A usage fee may be calculated. In this case, in order to determine whether it is a toll road taxiway, the current position of the vehicle is detected by the position detector 1 of the in-vehicle navigation device, and map matching with map data is performed, so that the road that is running Determine the type.
[0060]
When a vehicle approaches a prepaid toll gate such as a flat toll gate or a collection toll gate, it may be notified that the approaching gate facility is a prepaid toll gate or a toll to be paid in advance. In addition, if you pass through the toll gate, you can search for gate facilities on the route in advance to find the section to be used, so that it is not only a toll or prepaid toll gate, but also the name of the section and exit IC. May be notified to the user.
[0061]
In addition, when discount is applied within a certain period and / or a certain section, a charge considering the discount is provided for use of the toll road in the corresponding period or the corresponding section. At that time, the period can be determined by using a calendar built in the in-vehicle navigation device. And when using discounts, such as a round ticket, in which a user obtains a discount ticket in advance, the fact that the user owns the discount ticket corresponds to the operation switch group 7 (corresponding to the operating means in the present invention). ). In this way, it is determined that a discount ticket has been acquired even though it has not passed through the gate facility where the discount ticket can be acquired in S108 of FIG. 2, and the entered type of discount ticket passes through the available gate facility. Is determined to pass through the discount adaptation interval (S108: Yes).
[0062]
Furthermore, if the vehicle is an ETC-equipped vehicle and there is a fee discount by ETC, a fee that considers discounts by ETC is guided. In any case, when the fee considering the discount is guided, the reason for the discount is also guided at the same time.
