Description

The present invention relates to a toll collection system and a toll collection method.

Electronic toll collection system (ETC: Electronic Toll Collection System (registered trademark)) that collects tolls by electronic payment by wirelessly communicating with the on-board unit mounted on the vehicle as a system for collecting tolls on toll roads. , Also known as "automatic toll collection system").
On toll roads, different tolls may be charged depending on the vehicle type classification (for example, "light vehicle", "ordinary vehicle", "medium-sized vehicle", "large vehicle", and "extra-large vehicle"). Therefore, the vehicle type classification of the vehicle is registered in advance in the in-vehicle device. However, for example, depending on whether or not the vehicle is towing a towed vehicle such as a trailer, the vehicle type classification changes to a rank higher or lower than the vehicle type classification registered in the on-board unit (rank up or down). ) May. For this reason, in the automatic toll collection system, for example, an axle sensor that counts the number of axles of the vehicle is provided, and the actual vehicle type classification of the vehicle based on the number of axles (the vehicle type ranked up or down depending on the presence or absence of the towed vehicle). Classification) is determined.

In addition, as a toll road charging method, there are a distance toll system in which different tolls are charged according to the vehicle type and distance, and a flat toll system in which a fixed toll is charged for each vehicle type.
On toll roads where a distance-to-distance toll system is adopted, tollhouse facilities including the above-mentioned axle sensor and an antenna that can communicate with in-vehicle devices are installed at the entrance tollhouse, and vehicle types are classified based on the number of axles. In addition to the determination, the vehicle type classification and the entrance information indicating from which entrance tollhouse the toll road was entered may be written in the in-vehicle device via the antenna (see, for example, Patent Document 1). Then, an antenna capable of communicating with the on-board unit is provided at the exit tollhouse, and the vehicle type classification and entrance information written at the entrance tollhouse are acquired via the antenna. Then, the exit tollhouse collects the vehicle type classification determined by the entrance tollhouse and the toll according to the distance from the entrance tollhouse indicated by the entrance information. As a result, in the automatic toll collection system in the distance toll system, the toll collection process can be performed based on the actual vehicle type classification determined at the entrance tollhouse without determining the vehicle type classification at the exit tollhouse. it can.
On the other hand, on toll roads where a flat toll system is adopted, the axle sensor and antenna as described above are installed at either the entrance tollhouse or the exit tollhouse to determine the actual vehicle type classification of the vehicle and the vehicle type. Collect tolls set for each category. For example, on a toll road where an axle sensor and an antenna are installed at the exit tollhouse to collect tolls, these devices are not installed at the entrance tollhouse, and vehicles can enter the toll road without slowing down or stopping. There are cases.

Japanese Unexamined Patent Publication No. 2011-233089

There are cases where the toll road toll system is changed from a flat toll system to a distance toll system according to the guidelines from the government.
In the conventional automatic toll collection system applied to the distance toll system, it is necessary to determine the vehicle type classification at the entrance tollhouse, but at the entrance tollhouse of the toll road with a flat toll system, as described above, the axle sensor There are cases where a device for discriminating the vehicle type is not provided. For this reason, when changing the billing method from the flat rate system to the distance-to-distance charge system, it is necessary to add equipment to each of the entrance tollhouses, which requires a great deal of cost. Further, depending on the location conditions of the entrance tollhouse, it may be difficult to secure the installation space for the equipment.

In order to secure the installation space for the equipment and reduce the cost, it is conceivable to apply a system (free flow system) in which only the antenna is installed at the entrance tollhouse and wireless communication is performed with the vehicle. At this time, the entrance information acquired via the antenna is recorded in the vehicle-mounted device.
However, in the conventional automatic toll collection system applied to the distance toll system, the exit tollhouse does not determine the vehicle type classification, but the vehicle type classification determined at the entrance tollhouse is acquired from the on-board unit. Therefore, if only the antenna is installed at the entrance tollhouse, the actual vehicle type classification of the vehicle cannot be obtained at the exit tollhouse. As a result, when the vehicle type classification of the vehicle changes depending on the presence or absence of the towed vehicle, it may be difficult to collect an appropriate toll for the actual vehicle type classification of the vehicle.

The present invention has been made in view of such a problem, and is a toll collection system capable of collecting tolls according to the vehicle type classification while reducing the installation space and cost of equipment at the entrance tollhouse. And provide a method of collecting tolls.

In order to solve the above problems, the present invention employs the following means.
According to one aspect of the present invention, the toll collection system (1) provided at the exit toll station of a toll road and collects tolls with an on-board unit mounted on a vehicle traveling in a lane is the vehicle. A tread plate (12) that detects trampling by the vehicle and outputs a detection signal capable of identifying the number of lanes of the vehicle, and a discrimination process that determines the vehicle type of the vehicle based on the number of lanes and outputs it as the first vehicle type classification. A vehicle type determination device (10) having a unit (13), a first antenna (22) that wirelessly communicates with the on-board unit in a first communication area defined on the downstream side of the lane from the tread plate, and the above. Wireless communication with the on-board unit in a second communication area defined in a position downstream of the first communication area on the lane and at a position where the on-board unit can reach after the vehicle has passed the tread plate. The second antenna (23), the entrance information indicating the entrance toll station where the vehicle entered the toll road from the on-board unit, and the second vehicle type classification indicating the vehicle type of the vehicle are transmitted via the first antenna. Based on the information acquisition unit (241) that acquires the first vehicle type classification from the vehicle type determination device, the entrance information, the first vehicle type classification, and the second vehicle type classification. A toll determination unit (242) for determining the toll and writing the toll to the vehicle-mounted device via the first antenna and the second antenna is provided. The toll determination unit determines the toll based on the first vehicle type classification when the entrance information indicates an entrance tollhouse where the vehicle type cannot be determined, and when the entrance information indicates an entrance tollhouse where the vehicle type can be determined. The toll is determined based on the second vehicle type classification.
By having such a configuration, the toll determination unit has the first vehicle type classification acquired from the vehicle type determination device and the first vehicle type acquisition from the on-board unit according to which entrance tollhouse the vehicle entered the toll road. The toll can be determined based on one of the two vehicle type categories. As a result, even if the vehicle type classification changes depending on the presence or absence of the tolled vehicle, the toll determination unit will charge the toll based on the actual vehicle type classification determined at either the entrance tollhouse or the exit tollhouse. Therefore, it is possible to collect an appropriate toll for the actual vehicle type classification of the vehicle.
In addition, when the distance toll system is adopted at an entrance tollhouse where a vehicle type discrimination device is not installed, in the conventional toll collection system, a vehicle type discrimination device must be newly installed at the entrance tollhouse. However, in the toll collection system according to the above aspect, since the actual vehicle type classification can be determined by the vehicle type determination device at the exit tollhouse, it is not necessary to newly install the vehicle type determination device at the entrance tollhouse. Therefore, it is possible to adopt the distance toll system even in a narrow entrance tollhouse where the space for installing the vehicle type discrimination device cannot be secured. Further, the cost for installing the equipment at the entrance tollhouse can be reduced.

According to the second aspect of the present invention, the toll collection system according to the above aspect further includes an antenna control unit (243) for controlling the activation of the second antenna. The antenna control unit indicates an entrance tollhouse where the entrance information cannot determine the vehicle type, and when the vehicle enters the downstream side of the lane from the first communication area, the information acquisition unit performs the first. If the vehicle type classification of is not acquired, the second antenna is activated.
By having such a configuration, even if the vehicle length is long and the on-board unit cannot acquire the first vehicle type classification before leaving the first communication area, the toll collection system can be second. By activating the antenna, communication can be performed between the second antenna and the vehicle-mounted device in the second communication area.
In addition, if the entrance information indicates a tollhouse other than the entrance tollhouse where the vehicle type cannot be determined, or if the first vehicle type classification can be acquired while the on-board unit is located in the first communication area, the antenna control unit is the first. Since the two antennas are not activated, it is possible to reduce the possibility that unnecessary communication is performed between the second antenna and the on-board unit and a communication abnormality occurs.

According to the third aspect of the present invention, in the toll collection system of any one of the above aspects, the charge determination unit indicates an entrance tollhouse where the entrance information cannot determine the vehicle type, and the vehicle is the first. If the information acquisition unit has not acquired the first vehicle type classification when entering the downstream side of the lane from one communication area, the toll is written to the vehicle-mounted device via the second antenna. ..
By having such a configuration, even if the vehicle length is long and the vehicle-mounted device cannot acquire the first vehicle type classification before leaving the first communication area, the charge determination unit is second. The toll can be written to the on-board unit via the antenna. That is, even if the toll determination unit determines the toll after waiting for the vehicle type determination device to complete the determination of the vehicle type classification, the toll can be written to the in-vehicle device via the second antenna. Therefore, the toll determination unit can determine an appropriate toll for the actual vehicle type classification of the vehicle determined by the vehicle type determination device.

According to the fourth aspect of the present invention, the toll collection system according to any one of the above-described aspects stores in advance tollhouse information indicating whether or not the vehicle type classification of the vehicle can be determined at each of the entrance tollhouses. A storage unit (244) is further provided. When the tollhouse information associated with the entrance information indicates that the vehicle type classification cannot be determined, the tollhouse determination unit determines that the entrance information indicates an entrance tollhouse whose vehicle type cannot be determined.
With such a configuration, the tollhouse determination unit can easily and quickly determine whether or not the entrance information indicates an entrance tollhouse whose vehicle type cannot be determined based on the tollhouse information.

According to the fifth aspect of the present invention, at the exit toll station of the toll road, the toll collection method for collecting the toll with the in-vehicle device mounted on the vehicle traveling in the lane is trampled by the vehicle. A vehicle type determination step of specifying the number of lanes of the vehicle based on the detection signal output from the tread plate (12) to be detected, determining the vehicle type of the vehicle based on the number of lanes, and outputting as the first vehicle type classification. In the first communication area defined on the downstream side of the lane from the tread plate, the first communication step of wirelessly communicating with the vehicle-mounted device by the first antenna (22) and the first communication area. Also on the downstream side of the lane, in a second communication area defined at a position where the vehicle-mounted device can reach after the vehicle has passed the tread plate, the vehicle-mounted device and the vehicle-mounted device are wirelessly connected by the second antenna (23). The second communication step for communicating, the entrance information indicating the entrance toll station where the vehicle entered the toll road from the in-vehicle device, and the second vehicle type classification indicating the vehicle type of the vehicle are transmitted via the first antenna. Based on the information acquisition step for acquiring the first vehicle type classification determined in the vehicle type determination step, the entrance information, the first vehicle type classification, and the second vehicle type classification. It has a toll determination step of determining the toll and writing the toll to the vehicle-mounted device via the first antenna and the second antenna. In the toll determination step, when the entrance information indicates an entrance tollhouse where the vehicle type cannot be determined, the toll is determined based on the first vehicle type classification, and the entrance information indicates a tollhouse other than the entrance tollhouse where the vehicle type can be determined. , The toll is determined based on the second vehicle type classification.

According to the toll collection system and the toll collection method according to the present invention, it is possible to collect tolls according to the vehicle type classification of the vehicle while reducing the installation space and cost of the equipment at the entrance tollhouse.

(Functional configuration of toll collection system)
FIG. 2 is a diagram showing a functional configuration of a toll collection system according to an embodiment of the present invention.
Hereinafter, the functional configuration of the toll collection system 1 will be described with reference to FIG.
As shown in FIG. 2, the toll collection facility 100 of the toll collection system 1 includes a vehicle type determination device 10, a toll collection device 20, a roadside indicator 30, a start controller 40, and a start detector 50. ing.
The vehicle type discrimination device 10 includes a first vehicle detector 11, a tread plate 12, and a discrimination processing unit 13. Further, the toll collection device 20 includes a second vehicle detector 21, a first antenna 22, a second antenna 23, and a control unit 24.

In the first vehicle detector 11, the vehicle A exists at a position where the first vehicle detector 11 is arranged (that is, the upstream end of the first communication area Q1) in the lane direction (± X direction in FIG. 1). A vehicle detection signal N1 indicating whether or not the vehicle is detected is output to the discrimination processing unit 13 and the toll collection device 20.
Further, when the tread plate 12 detects the trampling by the tire of the vehicle A, the tread detection that can specify the number of axles of the vehicle A (that is, the number of times the tread plate 12 is stepped on by the tire), the tread width, and the tire width can be specified. The signal N2 is output to the discrimination processing unit 13.

The discrimination processing unit 13 specifies the feature information (number of axles, tread width, tire width, etc.) of the vehicle A based on the vehicle detection signal N1 and the stepping detection signal N2, and the discrimination processing unit 13 determines the feature information of the vehicle A based on the feature information. The vehicle type classification M1 (first vehicle type classification) is determined. The discrimination processing unit 13 outputs the vehicle type classification M1 of the discriminated vehicle A to the toll collection device 20.

In the second vehicle detector 21, the vehicle A exists at a position where the second vehicle detector 21 is arranged (that is, the downstream end of the first communication area Q1) in the lane direction (± X direction in FIG. 1). A vehicle detection signal N3 indicating whether or not the vehicle is detected is output to the control unit 24.

The control unit 24 includes an information acquisition unit 241, a charge determination unit 242, an antenna control unit 243, and a storage unit 244.

The information acquisition unit 241 first sets the history information R1 including the entrance information M2 indicating the entrance tollhouse where the vehicle A has entered the toll road and the vehicle type classification M3 (second vehicle type classification) indicating the vehicle type of the vehicle A. It is acquired from the vehicle-mounted device α mounted on the vehicle A via the antenna 22. In addition, the information acquisition unit 241 acquires the vehicle type classification M1 output from the vehicle type determination device 10.
In the present embodiment, the entrance information M2 and the vehicle type classification M3 perform wireless communication between the antenna provided at the entrance tollhouse and the vehicle-mounted device α (more specifically, the vehicle-mounted device α (more specifically, the vehicle-mounted device α). It is recorded on the IC card inserted in the device α).

FIG. 3 is a diagram for explaining the function of the toll collection system according to the embodiment of the present invention.
For example, as shown in FIG. 3, a plurality of entrance tollhouses T2, T3, T4, ... Are provided between the entrance tollhouse T1 which is the start point of the toll road and the exit tollhouse Tn which is the end point. To do. In addition, the toll road has a flat toll section (for example, from entrance tollhouse T1 to entrance tollhouse T4) where a flat toll system is adopted and a distance toll section (for example, entrance toll) where a distance toll system is adopted. (From T4 to the end point). The entrance tollhouse T4 in the distance toll section is provided with a toll collection facility 80 including a vehicle type determination device 81 and an antenna 82, but the entrance tollhouses T1 to T3 in the flat toll section are provided with a vehicle type determination device and an antenna. Etc. are not provided.
When adopting the distance toll system for all sections (T1 to Tn) of such a toll road, in the present embodiment, for example, at the entrance tollhouse T4 where the toll collection facility 80 is already provided, equipment is added. , The existing vehicle type discrimination device 81 and the antenna 82 are used as they are without any change. Since the vehicle type determination device 81 and the antenna 82 of the toll collection equipment 80 have the same configuration as the vehicle type determination device 10 and the first antenna 22 of the toll collection equipment 100, the description thereof will be omitted. Therefore, when the vehicle A enters from the entrance tollhouse T4, the vehicle type determination device 81 of the toll collection facility 80 determines the vehicle type classification M3 of the vehicle A. Then, the entrance information M2 indicating the entrance tollhouse T4 and the vehicle type classification M3 determined by the vehicle type determination device are written to the vehicle-mounted device α of the vehicle A via the antenna 82 of the toll collection facility 80. That is, when the vehicle A enters from the entrance tollhouse T4 provided with the vehicle type determination device 81, the vehicle type classification M3 acquired by the information acquisition unit 241 from the on-board unit α is ranked up or ranked depending on the presence or absence of the towed vehicle. The down is reflected.
Therefore, at the entrance tollhouse T4 where the vehicle type can be discriminated by the vehicle type discriminating device 81, the vehicle type device α is not the vehicle type classification registered in advance at the time of setting up the vehicle type device α, but the actual vehicle type discriminating device 81 discriminates. The vehicle type classification (vehicle type classification that is ranked up or down depending on the presence or absence of the towed vehicle) is recorded as the vehicle type classification M3.

On the other hand, at the entrance tollhouses T2 to T3 where the toll collection facility 81 is not provided, only the antenna 82 capable of wireless communication with the on-board unit α is newly installed in order to adopt the distance toll system. Further, the installation of the antenna 82 is omitted at the entrance tollhouse T1 which is the starting point. Since the antenna 82 has the same configuration as the antenna 82 of the toll collection facility 80, the description thereof will be omitted.
At the entrance tollhouses T2 to T3, since the vehicle type cannot be discriminated by the vehicle type discriminating device, the information indicating the actual vehicle type classification is not written in the on-board unit α, and only the entrance information M2 is written. In this case, the on-board unit α outputs the vehicle type classification registered in advance at the time of setting up the on-board unit α as the vehicle type classification M3 when performing wireless communication with the first antenna 22 of the exit tollhouse. That is, when the vehicle A enters from the entrance tollhouses T1 to T3 in which the vehicle type determination device 81 is not provided, the vehicle type classification M3 acquired by the information acquisition unit 241 from the on-board unit α is ranked up depending on the presence or absence of the towed vehicle. Or the rank down is not reflected.
Further, at the entrance tollhouse T1 where the antenna is not installed, the entrance information M2 and the vehicle type classification M3 are not recorded in the on-board unit α. However, since the antenna is not installed only at the entrance tollhouse T1 on this toll road, in the toll collection facility 100 at the exit tollhouse, if the entrance information M2 is not recorded in the in-vehicle device α, the vehicle A It is possible to identify that the vehicle has entered from the entrance tollhouse T1.
In another embodiment, the antenna 82 may be installed at the entrance tollhouse T1 as well.

Further, the information acquisition unit 241 is used for the "vehicle-mounted device ID" which is an identification number capable of identifying the vehicle-mounted device α, the "vehicle number" of the vehicle A on which the vehicle-mounted device α is mounted, and the electronic payment processing of the toll. You may further acquire the "card ID". The "on-board unit ID" and "vehicle number" are information registered in advance in the storage unit (not shown) of the on-board unit α at the time of setting up the on-board unit α, and the "card ID" is inserted into the on-board unit α. This is the information registered in the IC card.

The fare determination unit 242 determines the toll charge M4 for the vehicle A based on the vehicle type classification M1, the entrance information M2, and the vehicle type classification M3 acquired by the information acquisition unit 241.
Specifically, the toll determination unit 242 refers to the tollhouse information D1 stored in the storage unit 244 and determines whether or not the entrance information M2 indicates an "entrance tollhouse whose vehicle type cannot be determined". ..
FIG. 4 is a diagram showing an example of tollhouse information according to an embodiment of the present invention.
As shown in FIG. 4, in the tollhouse information D1, information indicating whether or not the vehicle type can be discriminated for each entrance tollhouse is registered. For example, since the vehicle type discrimination device is not installed at the entrance tollhouses T1 to T3, information (“impossible”) indicating that the vehicle type cannot be discriminated is registered. Further, since the vehicle type determination device 81 is installed at the entrance tollhouse T4, information (“OK”) indicating that the vehicle type can be determined is registered.
When the entrance information M2 indicates an "entrance tollhouse whose vehicle type cannot be determined", the vehicle type classification M3 acquired from the vehicle-mounted device α is the vehicle type classification registered in the vehicle-mounted device α at the time of setup. In this case, since the vehicle type classification M3 may differ from the actual vehicle type classification (vehicle type classification that reflects the rank up or rank down depending on the presence or absence of the towed vehicle), the charge determination unit 242 acquired the vehicle type determination device 10. The toll fee M4 is determined based on the vehicle type classification M1.
On the other hand, when the entrance information M2 indicates an "entrance tollhouse capable of discriminating the vehicle type", the vehicle type classification M3 acquired from the vehicle-mounted device α is the vehicle type classification determined by the vehicle type determination device 81 at the entrance tollhouse. In this case, since the vehicle type classification M3 indicates the actual vehicle type classification, the toll determination unit 242 determines the toll charge M4 based on the vehicle type classification M3 acquired from the vehicle-mounted device α.
The toll determination unit 242 may determine the toll by referring to a toll table predetermined for each combination of the entrance tollhouse and the vehicle type classification.
Further, the charge determination unit 242 writes the history information R1 including the determined toll charge M4 into the vehicle-mounted device α via the first antenna 22 and the second antenna 23. Further, the toll determination unit 242 outputs the toll M4 to the roadside display 30 and causes the roadside display 30 to present the amount of the toll M4 to the user.
Then, the charge determination unit 242 creates detailed information including the toll charge M4 and various information (card ID, etc.) acquired by the information acquisition unit 241 and transmits the detailed information to a central management server (not shown). , Performs electronic payment processing of tolls for vehicle A.

The antenna control unit 243 includes a vehicle detection signal N1 and a vehicle type classification M1 output from the vehicle type determination device 10, a vehicle detection signal N3 output from the second vehicle detector 21, and an entrance information M2 acquired by the information acquisition unit 241. Based on the above, the start and stop of the first antenna 22 and the second antenna 23 are controlled.
When the antenna control unit 243 detects that the vehicle A (vehicle-mounted device α) has reached the first communication area Q1 by receiving the vehicle detection signal N1 from the vehicle type discrimination device 10 (first vehicle detector 11), the antenna control unit 243 detects that the vehicle A (vehicle-mounted device α) has arrived at the first communication area Q1. The first antenna 22 is activated (radio wave radiation is turned on). Further, by receiving the vehicle detection signal N3 from the second vehicle detector 21, the vehicle A (vehicle-mounted device α) has entered the downstream side (-X side in FIG. 1) in the lane direction from the first communication area Q1. That is, when it is detected that the first communication area Q1 has been exited, the first antenna 22 is stopped (radio wave radiation is turned off).
Further, in the antenna control unit 243, when the entrance information M2 indicates the "entrance tollhouse where the vehicle type cannot be determined" and the vehicle A exits from the first communication area Q1, the information acquisition unit 241 is transmitted from the vehicle type determination device 10. If the vehicle type classification M1 has not been acquired, the second antenna 23 is activated. Then, when the antenna control unit 243 detects that the vehicle A (vehicle-mounted device α) has exited from the second communication area Q2 by receiving the exit detection signal N5 from the start detector 50, the antenna control unit 243 stops the second antenna 23. To do.

The tollhouse information D1 shown in FIG. 4 is stored in advance in the storage unit 244. Further, the charge table may be stored in advance in the storage unit 244.

(Processing flow of antenna control processing)
FIG. 5 is a first diagram showing a processing flow of the toll collection system according to the embodiment of the present invention.
Hereinafter, among the processing flows of the toll collection system 1, the flow of the antenna control processing in the antenna control unit 243 of the toll collection device 20 will be described with reference to FIG.
First, when the antenna control unit 243 receives the vehicle detection signal N1 from the vehicle type determination device 10 (first vehicle detector 11) (step S100), the antenna control unit 243 activates the first antenna 22 (step S101).

Next, the information acquisition unit 241 of the toll collection device 20 transmits the history information R1 including the entrance information M2 indicating the entrance tollhouse where the vehicle A has entered the toll road and the vehicle type classification M3 via the first antenna 22. Obtained from the vehicle-mounted device α mounted on the vehicle A (step S102).

Next, the antenna control unit 243 determines whether or not the entrance information M2 indicates the "entrance tollhouse capable of discriminating the vehicle type" by referring to the tollhouse information D1 (FIG. 4) stored in the storage unit 244 (FIG. 4). Step S103).
For example, when the entrance information M2 indicates the entrance tollhouse T4, the antenna control unit 243 determines that the entrance tollhouse T4 can "determine the vehicle type" by referring to the tollhouse information D1 (step S103: YES). On the other hand, for example, when the entrance information M2 indicates the entrance tollhouse T3, the antenna control unit 243 determines that the entrance tollhouse T3 "cannot determine the vehicle type" by referring to the tollhouse information D1 (step S103: NO). ..

When the entrance information M2 indicates "the entrance tollhouse capable of discriminating the vehicle type" (step S103: YES), the vehicle type classification M3 acquired from the on-board unit α is the actual vehicle type classification determined by the vehicle type determination device 81 of the entrance tollhouse. is there. In this case, the toll determination unit 242 can immediately execute the process of determining the toll charge M4 based on the vehicle type classification M3 and writing it to the vehicle-mounted device α without waiting for the determination result by the vehicle type determination device 10. Therefore, the antenna control unit 243 determines that the activation of the second antenna 23 is unnecessary, and proceeds to the next step without activating the second antenna 23.
Then, when the antenna control unit 243 receives the vehicle detection signal N3 from the second vehicle detector 21 (step S104), the antenna control unit 243 stops the first antenna 22 (step S105) and ends the antenna control process.

Further, when the entrance information M2 indicates an "entrance tollhouse whose vehicle type cannot be determined" (step S103: NO), the vehicle type classification M3 acquired from the vehicle-mounted device α is not an actual vehicle type classification but is registered in advance at the time of setting up the vehicle-mounted device α. It is a vehicle type classification that has been done. In this case, the toll determination unit 242 needs to wait until the vehicle type determination device 10 at the exit tollhouse acquires the vehicle type classification M1 determined, and then perform the process of determining the toll charge M4. However, when the vehicle length of the vehicle A is long, all the tires of the vehicle A do not pass through the tread 12 and the vehicle type discriminating device is used before the on-board unit α (the head portion of the vehicle A) exits the first communication area Q1. There is a possibility that the vehicle type determination in 10 is not completed.
Therefore, when the entrance information M2 indicates the "entrance tollhouse where the vehicle type cannot be determined", the antenna control unit 243 responds to the position of the vehicle A on the lane L and the timing when the vehicle type determination of the vehicle type determination device 10 is completed. Then, it is determined whether or not to activate the second antenna 23.
Specifically, first, the antenna control unit 243 determines whether or not the vehicle detection signal N3 has been received from the second vehicle detector 21 (step S106).
When the antenna control unit 243 has not received the vehicle detection signal N3 (step S106: NO), the antenna control unit 243 waits until the vehicle detection signal N3 is received. Further, when the antenna control unit 243 receives the vehicle detection signal N3 (step S106: YES), the vehicle A (vehicle-mounted device α) exits the first communication area Q1 and cannot communicate with the first antenna 22. The first antenna 22 is stopped (step S107).

When the vehicle detection signal N3 is received and the first antenna 22 is stopped, the antenna control unit 243 determines whether or not the vehicle type classification M1 has been acquired from the vehicle type determination device 10 (step S108). When the antenna control unit 243 receives the vehicle detection signal N3, that is, when the vehicle A (vehicle-mounted device α) exits the first communication area Q1, the vehicle type classification M1 has already been acquired (step S108: YES). ), The charge determination unit 242 considers that the process of determining the toll charge M4 based on the vehicle type classification M1 has been completed, and determines that the activation of the second antenna 23 is unnecessary. Therefore, the antenna control unit 243 ends the antenna control process without activating the second antenna 23.
Further, when the antenna control unit has not acquired the vehicle type classification M1 when receiving the vehicle detection signal N3 (step S108: NO), the antenna control unit considers that the processing in the charge determination unit 242 has not been completed, and the second antenna 23 Is started (step S109).

When the antenna control unit 243 receives the exit detection signal N5 after activating the second antenna 23 (step S110), the vehicle A (vehicle-mounted device α) exits the second communication area Q2 and becomes the second antenna 23. It is determined that the communication of the above is impossible, and the second antenna 23 is stopped (step S111). Then, the antenna control unit 243 ends the antenna control process.
The antenna control unit 243 repeatedly executes the above-mentioned antenna control process every time the vehicle enters the lane L.

(Processing flow of charge determination processing)
FIG. 6 is a second diagram showing a processing flow of the toll collection system according to the embodiment of the present invention.
Hereinafter, among the processing flows of the toll collection system 1, the flow of the charge determination processing in the charge determination unit 242 of the charge collection device 20 will be described with reference to FIG.
First, when the vehicle A (on-board unit α) arrives at the first communication area Q1, the information acquisition unit 241 of the toll collection device includes the entrance information M2 indicating the entrance tollhouse where the vehicle A has entered the toll road, and the vehicle type classification. The history information R1 including M3 is acquired from the vehicle-mounted device α via the first antenna 22 (step S200).

Next, the toll determination unit 242 refers to the tollhouse information D1 (FIG. 4) stored in the storage unit 244, and determines whether or not the entrance information M2 indicates an "entrance tollhouse capable of determining the vehicle type" ( Step S201).
When the entrance information M2 indicates "entrance tollhouse capable of discriminating vehicle type (for example, entrance tollhouse T4)" (step S201: YES), the vehicle type classification M3 acquired from the on-board unit α is determined by the vehicle type determination device 81 of the entrance tollhouse. It is the actual vehicle type classification that was done. In this case, the toll determination unit 242 determines the toll M4 of the vehicle A based on the vehicle type classification M3 acquired from the vehicle-mounted device α without waiting for the determination result by the vehicle type determination device 10 (step S202).
Further, when the charge determination unit 242 writes the history information R1 including the determined toll charge M4 into the vehicle-mounted device α via the first antenna 22 (step S203), the charge determination process ends.

On the other hand, when the entrance information M2 indicates "an entrance tollhouse whose vehicle type cannot be determined (for example, an entrance tollhouse T3)" (step S201: NO), the vehicle type classification M3 acquired from the on-board unit α is not an actual vehicle type classification but an on-board unit. This is a vehicle type classification registered in advance when the device α is set up. In this case, the fare determination unit 242 performs a fare determination process based on the vehicle type classification M1 acquired from the vehicle type determination device 10 in order to calculate an accurate toll based on the actual vehicle type classification.
Specifically, the charge determination unit 242 determines whether or not the vehicle type classification M1 has been acquired from the vehicle type determination device 10 (step S204).
If the charge determination unit 242 has not acquired the vehicle type classification M1 (step S204: NO), the charge determination unit 242 waits until the vehicle type classification M1 is acquired.
Further, when the toll determination unit 242 acquires the vehicle type classification M1 (step S204: YES), the toll determination unit 242 determines the toll charge M4 of the vehicle A based on the vehicle type classification M1 (step S205).

Then, when the toll fare M4 is determined, the fare determination unit 242 determines whether or not the vehicle A (vehicle-mounted device α) is located in the first communication area Q1 (step S206).
The charge determination unit 242 determines when the vehicle A is located in the first communication area Q1 (step S206: YES), that is, when the vehicle detection signal N3 is not received from the second vehicle detector 21. The history information R1 including the toll M4 is written to the vehicle-mounted device α via the first antenna 22 (step S203), and the toll determination process is completed.
On the other hand, the charge determination unit 242 determines when the vehicle A is not located in the first communication area Q1 (step S206: NO), that is, when the vehicle detection signal N3 is received from the second vehicle detector 21. The history information R1 including the toll M4 is written to the vehicle-mounted device α via the second antenna 23 (step S207), and the toll determination process is completed.
The toll determination unit 242 repeatedly executes the above-mentioned toll determination process each time the vehicle enters the lane L.

(Action effect)
As described above, the toll collection system 1 according to the present embodiment is provided at the exit toll station of the toll road and collects tolls with the in-vehicle device α mounted on the vehicle A traveling in the lane L. The toll collection system 1 determines the vehicle type of the vehicle A based on the tread plate 12 that detects the stepping by the vehicle A and outputs the stepping detection signal N2 that can specify the number of lanes of the vehicle, and the number of lanes. A vehicle type discriminating device 10 having a discriminating processing unit 13 that outputs as a vehicle type classification M1 (first vehicle type classification), and an in-vehicle device α and wireless in the first communication area Q1 defined on the downstream side of the lane L from the tread plate 12. A second antenna 22 for communication and a second position on the downstream side of the lane L from the first communication area Q1 where the vehicle-mounted device α can reach after the vehicle A has passed the tread plate 12. In the communication area Q2, the second antenna 23 that wirelessly communicates with the vehicle-mounted device α, the entrance information M2 indicating the entrance toll station where the vehicle A has entered the toll road from the vehicle-mounted device α, and the vehicle type classification M3 indicating the vehicle type of the vehicle A. (Second vehicle type classification) is acquired via the first antenna 22, and the information acquisition unit 241 that acquires the vehicle type classification M1 from the vehicle type discrimination device 10, the entrance information M2, the vehicle type classification M1, and the vehicle type classification M3. The toll M4 is determined based on the above, and a toll determination unit 242 for writing the toll M4 to the vehicle-mounted device α via the first antenna 22 and the second antenna 23 is provided. When the entrance information M2 indicates an "entrance tollhouse where the vehicle type cannot be determined", the toll determination unit 242 determines the toll M4 based on the vehicle type classification M1 acquired from the vehicle type determination device 10, and the entrance information M2 can "determine the vehicle type". When indicating "entrance tollhouse", the toll toll M4 is determined based on the vehicle type classification M3 acquired from the on-board unit α.
By having such a configuration, the toll determination unit 242 acquires from the vehicle type classification M1 acquired from the vehicle type determination device 10 and the vehicle-mounted device α according to which entrance tollhouse the vehicle A entered the toll road. The toll M4 can be determined based on either one of the vehicle type classification M3. That is, even if the vehicle type classification of the vehicle A changes depending on the presence or absence of the tolled vehicle, the toll determination unit 242 passes based on the actual vehicle type classification determined at either the entrance tollhouse or the exit tollhouse. Since the toll M4 can be determined, it is possible to collect an appropriate toll for the actual vehicle type classification of the vehicle A. At this time, when the entrance information M2 indicates the "entrance tollhouse capable of discriminating the vehicle type", the toll determination unit 242 determines the toll M4 based on the vehicle type classification M3 acquired from the vehicle-mounted device α, so that the vehicle type determination device 10 determines the toll. The toll determination process can be completed without waiting for the vehicle type classification to be completed. Therefore, it is possible to increase the processing speed in the charge determination unit 242.
Further, when the distance toll system is adopted at the entrance tollhouse where the vehicle type discrimination device 81 is not installed, in the conventional toll collection system, the vehicle type discrimination device 81 must be newly installed at the entrance tollhouse. However, in the toll collection system 1 according to the present embodiment, since the actual vehicle type classification (vehicle type classification M1) can be determined by the vehicle type determination device 10 at the exit tollhouse, a vehicle type determination device 81 is newly added to the entrance tollhouse. No need to install. Therefore, it is possible to adopt the distance toll system even in a narrow entrance tollhouse where the space for installing the vehicle type discrimination device 81 cannot be secured.
Further, since only the antenna 82 needs to be installed at the entrance tollhouse as in the entrance tollhouses T2 to T3 in FIG. 3, the cost for installing the equipment can be reduced. Further, as in the entrance tollhouse T1 in FIG. 3, even if the entrance information M2 is not recorded, if it can be specified that the vehicle has entered the toll road from the entrance tollhouse T1, the antenna 82 may be omitted. Good. As a result, the cost for installing the device can be further reduced.

Further, the toll collection system 1 according to the above-described embodiment further includes an antenna control unit 243 that controls the activation of the second antenna 23. In the antenna control unit 243, the information acquisition unit 241 indicates the vehicle type when the entrance information M2 indicates an "entrance tollhouse whose vehicle type cannot be determined" and the vehicle A enters the downstream side of the lane L from the first communication area Q1. If the vehicle type classification M1 has not been acquired from the discrimination device 10, the second antenna 23 is activated.
By having such a configuration, even if the vehicle length of the vehicle A is long and the vehicle type classification M1 cannot be acquired before the vehicle-mounted device α leaves the first communication area Q1, the toll collection system 1 can be used. By activating the second antenna 23, communication can be performed between the second antenna 23 and the vehicle-mounted device α in the second communication area Q2.
Further, when the entrance information M2 indicates an "entrance tollhouse capable of discriminating the vehicle type", or when the vehicle type classification M1 can be acquired from the vehicle type discriminating device 10 while the on-board unit α is located in the first communication area Q1. Since the antenna control unit 243 does not activate the second antenna 23, it is possible to reduce the possibility that unnecessary communication is performed between the second antenna 23 and the vehicle-mounted device α and a communication abnormality occurs.

Further, in the toll collection system 1 according to the above-described embodiment, the toll collection unit 242 indicates that the entrance information M2 indicates an "entrance tollhouse whose vehicle type cannot be determined", and the vehicle A is in the lane L rather than the first communication area Q1. If the information acquisition unit 241 has not acquired the vehicle type classification M1 from the vehicle type determination device 10 when entering the downstream side of the vehicle, the toll M4 is written to the vehicle-mounted device α via the second antenna 23.
By having such a configuration, even if the vehicle length of the vehicle A is long and the vehicle type classification M1 cannot be acquired before the vehicle-mounted device α exits the first communication area Q1, the charge determination unit 242 can obtain the vehicle type classification M1. The toll M4 can be written to the vehicle-mounted device α via the second antenna 23. That is, even if the toll determination unit 242 waits for the vehicle type determination device 10 to complete the determination of the vehicle type classification M1 and determines the toll charge M4, the charge determination unit 242 writes the toll charge M4 to the vehicle-mounted device α via the second antenna 23. be able to. Therefore, the fare determination unit 242 can determine an appropriate toll M4 for the actual vehicle type classification (vehicle type classification M1) of the vehicle A determined by the vehicle type determination device 10.

Further, the toll collection system 1 according to the above-described embodiment further includes a storage unit 244 that stores in advance the tollhouse information D1 indicating whether or not the vehicle type classification can be determined at each of the entrance tollhouses. When the tollhouse information D1 associated with the entrance information M2 indicates that the vehicle type classification cannot be determined, the charge determination unit 242 determines that the entrance information M2 indicates an "entrance tollhouse whose vehicle type cannot be determined".
With such a configuration, the tollhouse determination unit 242 can easily and quickly determine whether or not the entrance information M2 indicates an "entrance tollhouse whose vehicle type cannot be determined" based on the tollhouse information D1.

Although the embodiments of the present invention have been described in detail above, they are not limited to these as long as they do not deviate from the technical idea of the present invention, and some design changes and the like are possible.
For example, in the above-described embodiment, the mode in which the information indicating whether or not the vehicle type can be determined for each entrance tollhouse is registered in the tollhouse information D1 has been described, but the present invention is not limited to this. In another embodiment, only the "entrance tollhouse whose vehicle type cannot be determined" may be registered in the tollhouse information D1. Then, when the entrance tollhouse indicated by the entrance information M2 is registered in the tollhouse information D1, the charge determination unit 242 may determine that it is an "entrance tollhouse whose vehicle type cannot be determined". By doing so, it is possible to reduce the amount of information in the tollhouse information D1 and simplify the processing in the tollhouse determination unit 242.

Further, in the above-described embodiment, the discrimination processing unit of the vehicle type discrimination device 10 determines the vehicle A based on the vehicle detection signal N1 received from the first vehicle detector 11 and the stepping detection signal N2 received from the tread plate 12. Although the aspect of specifying the feature information and determining the vehicle type classification M1 has been described, the present invention is not limited to this. In another embodiment, the vehicle type determination device 10 is a license plate reading device and a vehicle length that output a detection signal capable of identifying the license plate information (license plate number, plate size, etc.), vehicle length, and vehicle height of the vehicle A. It may further have a detector and a vehicle height detector. Then, the discrimination processing unit 13 identifies the characteristic information (license plate information, vehicle length, vehicle height) of the vehicle A based on the vehicle detection signal N1 and the stepping detection signal N2 and the detection signals received from these devices. However, the vehicle type classification M1 may be determined. As a result, the accuracy of the discrimination processing of the vehicle type classification M1 in the discrimination processing unit 13 can be improved. These devices can be added or omitted depending on the installation space of the exit tollhouse.
