Description

Embodiments of the present invention relate to a fee processing system, an exit processing device, a central device, and an exit fee processing method.

In the ETC (Electronic Toll Collection, registered trademark) system, which is widely used on toll roads, the entrance processing device at the entrance toll booth communicates wirelessly with the onboard device of the vehicle traveling in the entrance lane, and the exit processing device at the exit toll booth communicates wirelessly with the onboard device of the vehicle traveling in the exit lane after passing through the entrance lane. In this way, wireless communication at each toll booth allows non-stop toll collection without having to stop the vehicle at the entrance or exit.

For example, the entrance processing device receives vehicle identification information including the card identification information of the ETC card and the on-board device identification information of the on-board device from the vehicle's on-board device, and also transmits the entrance identification information stored in the entrance processing device to the on-board device. The on-board device receives the entrance identification information and writes it to the ETC card. The exit processing device also receives vehicle identification information and entrance identification information from the vehicle's on-board device, determines the travel section from the entrance identification information and the exit identification information stored in the exit processing device, calculates the toll based on the toll table and the travel section stored in the exit processing device, transmits the calculated toll to the on-board device, and also displays it on a roadside display.

When calculating tolls at each exit processing device, a fee table needs to be distributed in advance from the central device to each exit processing device, and the fee table needs to be updated periodically. In addition, when applying tolls according to time of day, a fee table for each time of day is required, and when providing tolls according to the toll route, a fee table for each toll route is required, so there is concern about an increase in the amount of information distributed from the central device to each exit processing device. In order to reduce the burden associated with distributing such fee tables, etc., there is a demand for a mechanism for calculating tolls by a central device.

The present invention aims to solve the above problems and provide a toll processing system, an exit processing device, a central device, and an exit toll processing method for realizing toll calculation by a central device.

The central device according to the embodiment includes a receiving unit that receives the first vehicle identification information and the first entrance identification information transmitted from a first entrance processing device, which receives the first vehicle identification information transmitted from a first vehicle-mounted device of a first vehicle traveling through a first entrance lane, and receives the first vehicle identification information and the exit identification information transmitted from an exit processing device, which receives the first vehicle identification information transmitted from the first vehicle-mounted device of the first vehicle traveling through the first entrance lane and the exit lane; a central fee calculation unit that calculates a centrally calculated toll based on a first traffic section determined from the first entrance identification information and the exit identification information and a central fee table; and a transmitting unit that transmits the centrally calculated toll to the exit processing device for transmission from the exit processing device to the first vehicle-mounted device.

The control unit 12 selects the entry record and the passage record corresponding to the entry record based on the vehicle identification information included in the entry record. In other words, the control unit 12 selects the entry record, the passage record, and the entry record that include the same vehicle identification information.
The control unit 12 determines the travel section, travel route, and travel date and time based on the selected entry record, passage record, and exit record, and calculates the centrally calculated toll based on the travel section, travel route, and travel date and time, the basic toll table, and the variable toll table (ST114).
The device communication unit 11 of the central device 1 transmits the centrally calculated toll to the exit toll gate device 3A (ST115).

When the upper communication unit 31A of the exit toll gate device 3A receives the centrally calculated toll from the central device 1 (ST314A), the vehicle communication unit 35A of the exit toll gate device 3A transmits the centrally calculated toll to the vehicle-mounted device 5 (ST315A).
The roadside display 34A displays the centrally calculated toll. The device communication unit 51 of the vehicle-mounted device 5 receives the centrally calculated toll (ST515), and the storage unit 53 stores the centrally calculated toll.

As a result, when an on-board unit 5 that has undergone entrance processing by the entrance toll booth device 2A undergoes exit processing by the exit toll booth device 3A, the entrance identification information sent from that on-board unit 5 is included in the entrance list L (because it is confirmed that entrance processing has been completed by the entrance toll booth device 2A that supports central calculation), it can receive the centrally calculated toll.

Figure 5 is a sequence diagram illustrating the calculation of tolls when a vehicle that enters through an entrance toll gate device that does not support central calculation in a central calculation-compatible ETC system of the first embodiment exits through an exit toll gate that supports central calculation.
When the vehicle passes through the second entrance lane corresponding to the entrance toll booth equipment 2B, the entrance toll booth equipment 2B communicates with the vehicle-mounted unit 5 of the vehicle and executes entrance processing.
That is, the device communication unit 51 of the vehicle-mounted device 5 transmits the vehicle identification information including the card identification information and the vehicle-mounted device identification information (ST521).
The vehicle communication unit 25A of the entrance toll booth equipment 2A receives the vehicle identification information transmitted from the equipment communication unit 51 of the vehicle-mounted unit 5 (ST221B), and transmits entrance information including the entrance identification information and the entry date and time to the vehicle-mounted unit 5 (ST222B).
When the device communication unit 51 of the vehicle-mounted device 5 receives the entrance information (ST522), the card processing unit 54 writes the entrance information into the ETC card.

When the vehicle that has passed through the second entrance lane travels along the predetermined route corresponding to the route device 4, the route device 4 communicates with the vehicle-mounted device 5 of the vehicle and executes route processing.
That is, the device communication unit 51 of the vehicle-mounted device 5 transmits the vehicle identification information (ST523).
The vehicle communication unit 45 of the route device 4 receives the vehicle identification information transmitted from the device communication unit 51 (ST421), and the upper communication unit 41 transmits a passage record including the vehicle identification information, route identification information, and passage date and time to the central device 1 (ST422).
The device communication unit 11 of the central device 1 receives the passage record (ST121), and the memory unit 13 stores the passage record.

When the vehicle, having passed through the second entrance lane and the predetermined route, passes through the first exit lane corresponding to the exit toll booth equipment 3A, the exit toll booth equipment 3A communicates with the vehicle-mounted unit 5 of the vehicle and executes exit processing.
That is, the device communication unit 51 of the vehicle-mounted device 5 transmits the vehicle identification information and the entrance information (ST524).
The vehicle communication unit 35A of the exit toll booth equipment 3A receives the vehicle identification information and the entrance information transmitted from the equipment communication unit 51 (ST321A).
Then, the control unit 32A of the exit toll gate device 3A judges the entrance toll gate through which the vehicle has passed based on the entrance identification information included in the received entrance information (ST322A). In other words, the control unit 32A judges whether the entrance identification information included in the received entrance information is included in the entrance list L or not.
If the entrance identification information is not included in the entrance list L, the control unit 32A determines the travel section and calculates the toll based on the basic toll table stored in the memory unit 36A. That is, the control unit 32A determines the travel section based on the entrance identification information included in the entrance information and the exit identification information stored in the memory unit 36A, and outputs the exit-calculated toll based on the travel section and the basic toll table (ST323A).
The vehicle communication unit 35A of the exit toll gate device 3A transmits the exit calculated toll to the vehicle-mounted device 5 (ST324A).
In addition, the roadside display 34A displays the exit-calculated toll.

When the device communication unit 51 of the vehicle-mounted device 5 receives the exit-calculated toll (ST525), the storage unit 53 stores the exit-calculated toll.
Furthermore, the higher level communication unit 31A of the exit toll gate device 3A transmits toll processing information including the vehicle identification information, entry information, exit information, and the exit calculated toll, etc. to the central equipment 1 (ST325A).
The device communication unit 11 of the central device 1 receives the toll processing information (ST122), and the storage unit 13 stores the toll processing information.

As a result, when an on-board unit 5 that has undergone entrance processing by the entrance toll booth device 2B undergoes exit processing by the exit toll booth device 3A, the entrance identification information sent from that on-board unit 5 is not included in the entrance list L (because it is not confirmed that entrance processing has been completed by the entrance toll booth device 2A that supports central calculation), so the on-board unit 5 can receive the exit calculated toll instead of the centrally calculated toll.

Figure 6 is a sequence diagram illustrating the calculation of tolls when a vehicle that enters through a central calculation-compatible entrance toll gate in a central calculation-compatible ETC system of the first embodiment exits through an exit toll gate that does not support central calculation.
When a vehicle passes through the first entrance lane corresponding to the entrance toll booth equipment 2A, the entrance toll booth equipment 2A communicates with the vehicle-mounted unit 5 of the vehicle and executes entrance processing.
That is, the device communication unit 51 of the vehicle-mounted device 5 transmits the vehicle identification information including the card identification information and the vehicle-mounted device identification information (ST531).
The vehicle communication unit 25A of the entrance toll booth equipment 2A receives the vehicle identification information transmitted from the equipment communication unit 51 of the vehicle-mounted unit 5 (ST231A), and transmits entrance information including the entrance identification information and the entry date and time to the vehicle-mounted unit 5 (ST232A).
When the device communication section 51 of the vehicle-mounted device 5 receives the entrance information (ST532), the card processing section 54 writes the entrance information into the ETC card.
Furthermore, the higher-level communication unit 21A of the entrance toll booth equipment 2A transmits an entrance record including the vehicle identification information and the entrance information to the central equipment 1 (ST233A).
When the device communication unit 11 of the central device 1 receives the entrance record (ST131), the storage unit 13 stores the entrance record.

When a vehicle that has passed through the first entrance lane travels along a predetermined route corresponding to the route device 4, the route device 4 communicates with the on-board device 5 of the vehicle and executes route processing.
That is, the device communication unit 51 of the vehicle-mounted device 5 transmits the vehicle identification information (ST533). When the vehicle communication unit 45 of the route device 4 receives the vehicle identification information transmitted from the device communication unit 51 of the vehicle-mounted device 5 (ST431), the upper communication unit 41 of the route device 4 transmits a passage record including the vehicle identification information, the route identification information, and the passage date and time to the central device 1 (ST432).
When the device communication unit 11 of the central device 1 receives the passage record (ST132), the memory unit 13 stores the passage record.

When a vehicle that has passed through the first entrance lane and the specified route passes through the second exit lane corresponding to the exit toll booth equipment 3B, the exit toll booth equipment 3B communicates with the vehicle-mounted unit 5 of the vehicle and executes exit processing.
That is, the device communication unit 51 transmits the vehicle identification information and the entrance information (ST534).
The vehicle communication unit 35B of the exit toll booth equipment 3B receives the vehicle identification information and the entrance information transmitted from the equipment communication unit 51 of the on-board unit 5 (ST331B).
The control unit 32B of the exit toll booth equipment 3B determines the passage section based on the entrance identification information included in the entrance information and the exit identification information stored in the memory unit 36B, and calculates the toll based on the passage section and the basic toll table stored in the memory unit 36B (ST332B).
Then, the vehicle communication unit 35B of the exit toll gate device 3B transmits the exit calculated toll to the vehicle-mounted device 5 (ST323B). Also, the roadside display 34B displays the exit calculated toll.

When the device communication unit 51 of the vehicle-mounted device 5 receives the exit-calculated toll (ST535), the storage unit 53 stores the exit-calculated toll.
Furthermore, the higher level communication unit 31B of the exit toll gate device 3B transmits toll processing information including the vehicle identification information, entry information, exit information, and the exit calculated toll, etc. to the central equipment 1 (ST324B).
When the device communication unit 11 of the central device 1 receives the toll processing information (ST133), the storage unit 13 stores the toll processing information.

As a result, when the on-board device 5 that has undergone entrance processing by the entrance toll booth device 2A undergoes exit processing by the exit toll booth device 3B, it can receive the exit calculated toll instead of the centrally calculated toll.

Figure 7 is a flowchart showing an example of the first exit process by the exit toll booth device compatible with central calculation according to the first embodiment. An example of the exit process by the exit toll booth device 3A compatible with central calculation has been described in Figures 4 to 6, but this flowchart provides a more detailed explanation of the selection and output of the centrally calculated toll or the exit calculated toll in the exit process by the exit toll booth device 3A.

As shown in FIG. 7, the vehicle communication unit 35A of the exit toll booth equipment 3A receives the vehicle identification information and the entrance information transmitted from the equipment communication unit 51 of the vehicle-mounted device 5 (ST341A).
The control unit 32A of the exit toll gate device 3A determines whether or not the entrance identification information included in the received entrance information is included in the entrance list L (ST342A).
If the entrance identification information is included in the entrance list L (ST342A, YES), the higher-level communication unit 31A of the exit toll booth equipment 3A transmits an exit record including the vehicle identification information, exit identification information, and exit date and time to the central device 1 (ST343A).
Next, the upper communication section 31A of the exit toll gate device 3A receives the centrally calculated toll calculated by the central device 1 from the central device 1 (ST345A).
The vehicle communication unit 35A transmits the centrally calculated toll to the vehicle-mounted device 5 (ST346A).

Also, if the entrance identification information is not included in the entrance list L (ST342A, NO), the control unit 32A of the exit toll booth equipment 3A determines the passage section based on the entrance identification information and the exit identification information stored in the memory unit 36A, and calculates the toll based on the passage section and the basic toll table (ST347A).
Then, vehicle communication unit 35A of exit toll booth device 3A transmits the exit calculated toll calculated in ST347A (ST348A).

As a result, it is possible to selectively output the centrally calculated toll or the exit calculated toll based on whether the entrance identification information is included in the entrance list L. If the on-board device 5 that has undergone entrance processing by the entrance toll booth device 2A undergoes exit processing by the exit toll booth device 3A, it can receive the centrally calculated toll. If the on-board device 5 that has undergone entrance processing by the entrance toll booth device 2A undergoes exit processing by the exit toll booth device 3B, it can receive the exit calculated toll.

Second Embodiment
Fig. 8 is a flowchart showing an example of the second exit process by the central calculation compatible exit toll booth device according to the second embodiment. In the explanation of the second exit process, the differences from the first exit process explained in Fig. 7 will be mainly explained, and explanations of substantially the same parts will be omitted as appropriate.

As shown in FIG. 8, the vehicle communication unit 35A of the exit toll booth equipment 3A receives the vehicle identification information and the entrance information transmitted from the equipment communication unit 51 of the on-board device 5 (ST351A).
If the entrance identification information is included in the entrance list L (ST352A, YES), the higher-level communication unit 31A of the exit tollgate equipment 3A transmits the exit record to the central equipment 1 (ST353A).
Then, control unit 32A determines the travel section based on the entrance identification information and the exit identification information stored in storage unit 36A, and calculates the toll based on the travel section and the basic toll table (ST354A).
Note that the transmission of ST353A and the calculation of ST354A are independent processes, and the order of the transmission of ST353A and the calculation of ST354A is not particularly limited; either one may be performed first, or they may be performed simultaneously.

If the higher-level communication unit 31A of the exit toll gate equipment 3A receives the centrally calculated toll from the central device 1 within a certain period of time (ST355A, YES), the vehicle communication unit 35A transmits the centrally calculated toll to the vehicle-mounted device 5 (ST356A).
If the upper communication unit 31A of the exit toll gate equipment 3A does not receive the centrally calculated toll from the central device 1 within a certain period of time (ST355A, NO), the vehicle communication unit 35A of the exit toll gate equipment 3A transmits the exit calculated toll calculated in ST354A to the vehicle-mounted unit 5 (ST359A).

If the entrance identification information is not included in the entrance list L (ST352A, NO), control unit 32A calculates the toll based on the travel section and the basic toll table (ST357A).
Then, the vehicle communication unit 35A transmits the exit-calculated toll calculated in ST357A to the vehicle-mounted device 5 (ST358A).

As a result, the exit calculated toll can be sent instead of the centrally calculated toll before the time required to send the centrally calculated toll to the on-board device 5 exceeds the allowable time for exit processing. This makes it possible to achieve smooth toll collection without vehicles being held up in the exit lane.

Third Embodiment
Fig. 9 is a flowchart showing an example of the third exit process by the central calculation compatible exit toll booth device according to the third embodiment. In the explanation of the third exit process, the differences from the first and second exit processes explained in Fig. 7 and Fig. 8 will be mainly explained, and explanations of substantially the same parts will be omitted as appropriate.

In the third exit process, a case will be described in which the device communication unit 51 of the vehicle-mounted device 5 transmits vehicle identification information and entrance information at different times, and a case will be described in which the device communication unit 51 transmits card identification information, vehicle-mounted device identification information, and entrance information at different times. For example, a case will be described in which the vehicle identification information is transmitted first and then the entrance information is transmitted, or a case will be described in which the card identification information is transmitted first and then the vehicle-mounted device identification information and entrance information are transmitted.

As shown in FIG. 9, the vehicle communication unit 35A of the exit toll booth equipment 3A receives vehicle identification information, or card identification information from the equipment communication unit 51 of the onboard unit 5 (ST360A), and the higher-level communication unit 31A transmits the vehicle identification information and exit identification information, or the card identification information and exit identification information, to the central device 1 (ST361A).
Next, the vehicle communication unit 35A of the exit toll booth device 3A receives the entrance information, or the vehicle-mounted unit identification information and the entrance information, from the vehicle-mounted unit 5 (ST362A).

When the device communication unit 11 of the central device 1 receives the vehicle identification information and exit identification information, or the card identification information and exit identification information, the control unit 12 calculates the centrally calculated toll based on the received card identification information and exit identification information. The device communication unit 11 then transmits the centrally calculated toll to the exit toll booth device 3A. To elaborate on the centrally calculated toll, the control unit 12 selects an entry record and a passage record that contain the same card identification information as the received card identification information, determines the passage section and passage route based on the entry identification information contained in the entry record, the route identification information contained in the passage record, and the received exit identification information, and calculates the centrally calculated toll based on the passage section and passage route, the basic fee table, and the variable fee table.

Returning to the explanation of the third exit process by the exit toll booth equipment 3A.
If the entrance identification information included in the received entrance information is included in the entrance list L (ST363A, YES), the control unit 32A of the exit toll booth equipment 3A determines the passage section based on the entrance identification information and the exit identification information stored in the memory unit 36A, and calculates the toll based on the passage section and the basic toll table (ST364A).

If the higher-level communication unit 31A of the exit toll gate equipment 3A receives the centrally calculated toll from the central device 1 within a certain period of time (ST365A, YES), the vehicle communication unit 35A transmits the centrally calculated toll to the vehicle-mounted device 5 (ST366A).
On the other hand, if the upper communication unit 31A of the exit toll gate equipment 3A does not receive the centrally calculated toll from the central device 1 within a certain period of time (ST365A, NO), the vehicle communication unit 35A transmits the exit calculated toll calculated in ST364A to the vehicle-mounted device 5 (ST369A).

Also, if the entrance identification information is not included in the entrance list L (ST363A, NO), the control unit 32A calculates the toll based on the travel section and the basic toll table (ST367A), and the vehicle communication unit 35A transmits the exit calculated toll calculated in ST367A to the vehicle-mounted device 5 (ST368A).

In addition, it is also possible to omit the determination of whether the entrance identification information is included in the entrance list L (ST363A) and execute ST364A.

As a result, the exit-calculated toll can be transmitted instead of the centrally calculated toll before the time required to transmit the centrally calculated toll to the on-board device 5 exceeds the allowable time for the exit process. This makes it possible to realize smooth toll collection without causing vehicles to stagnate in the exit lane.
In addition, in response to receiving the card identification information or the vehicle identification information from the on-board unit 5, the exit toll booth device 3A transmits the card identification information and the exit identification information, or the vehicle identification information and the exit identification information, to the central device 1 without waiting for the entrance information transmitted from the on-board unit 5. This enables the central device to start calculating the toll at an earlier timing, which is expected to reduce the delay in calculating the toll.

(Fourth embodiment)
10 is a sequence diagram illustrating toll calculation by a central calculation-compatible ETC system according to the fourth embodiment. In the fourth embodiment, even a vehicle that has undergone entrance processing by the entrance toll booth device 2B can receive a centrally calculated toll in exit processing by the exit toll booth device 3A. Therefore, in the fourth embodiment, just as the entrance toll booth device 2A is central calculation-compatible, the entrance toll booth device 2B is also central calculation-compatible. In the explanation of the fourth embodiment, the differences from the first embodiment will be mainly explained, and explanations of substantially the same parts will be omitted as appropriate.

When the vehicle passes through the second entrance lane corresponding to the entrance toll booth equipment 2B, the entrance toll booth equipment 2B communicates with the vehicle-mounted unit 5 of the vehicle and executes entrance processing.
That is, the device communication unit 51 of the vehicle-mounted device 5 transmits the vehicle identification information including the card identification information and the vehicle-mounted device identification information (ST571).
The vehicle communication unit 25A of the entrance toll booth equipment 2A receives the vehicle identification information transmitted from the equipment communication unit 51 (ST271B), and transmits entrance information including the entrance identification information and the entry date and time to the vehicle-mounted unit 5 (ST272B).
The device communication unit 51 of the vehicle-mounted device 5 receives the entrance information (ST572), and the card processing unit 54 writes the entrance information into the ETC card.

When the vehicle that has passed through the second entrance lane travels along the predetermined route corresponding to the route device 4, the route device 4 communicates with the vehicle-mounted device 5 of the vehicle and executes route processing.
That is, the device communication unit 51 transmits the vehicle identification information (ST573).
The vehicle communication unit 45 of the route device 4 receives the vehicle identification information transmitted from the device communication unit 51 (ST471), and the upper communication unit 41 transmits a passage record including the vehicle identification information, route identification information, and passage date and time to the central device 1 (ST472).
The device communication unit 11 of the central device 1 receives the passing record (ST171), and the memory unit 13 stores the passing record.

When the vehicle, having passed through the second entrance lane and the predetermined route, passes through the first exit lane corresponding to the exit toll booth equipment 3A, the exit toll booth equipment 3A communicates with the vehicle-mounted unit 5 of the vehicle and executes exit processing.
That is, the device communication unit 51 of the vehicle-mounted device 5 transmits the vehicle identification information and the entrance information (ST574).
The vehicle communication unit 35A of the exit toll booth equipment 3A receives the vehicle identification information and the entrance information from the equipment communication unit 51 of the on-board unit 5 (ST371A).
The upper communication unit 31A of the exit toll booth device 3A transmits the vehicle identification information, the entrance information, and the exit information to the central equipment 1 (ST372A).
The device communication unit 11 of the central device 1 receives the vehicle identification information, the entrance information, and the exit information (ST172).

The storage section 13 of the central device 1 stores the entrance list L, and the control section 12 determines whether or not the entrance identification information included in the received entrance information is included in the entrance list L (ST173A).
If the vehicle has been subjected to entrance processing by the entrance toll booth device 2A, that is, if the entrance identification information is included in the entrance list L, the control unit 12 of the central device 1 selects a passage record corresponding to the received vehicle identification information based on this vehicle identification information, and determines the travel section, travel route, and travel date and time based on the entrance information, exit information, and passage record. Then, the centrally calculated toll is calculated based on the travel section, travel route, and travel date and time, the basic toll table, and the variable toll table (ST174).
On the other hand, as shown in ST272B, when entrance processing is being performed by the entrance toll booth equipment 2B, that is, when the entrance identification information is not included in the entrance list L, the control unit 12 of the central device 1 calculates the centrally calculated toll based on the travel section and the basic toll table (ST174).
The device communication unit 11 of the central device 1 transmits the calculated centrally calculated toll to the exit toll gate device 3A (ST175).

The upper communication unit 31A of the exit toll gate device 3A receives the centrally calculated toll from the central equipment 1 (ST373A). The vehicle communication unit 35A of the exit toll gate device 3A transmits the centrally calculated toll to the vehicle-mounted device 5 (ST374A).
When the device communication unit 51 of the vehicle-mounted device 5 receives the centrally calculated toll (ST575), the storage unit 53 stores the centrally calculated toll.

Even if the entrance process is performed by the entrance toll booth device 2B, the centrally calculated toll may be calculated based on the travel section, travel route, and travel date and time, as well as the basic toll table and the variable toll table.

As described above, when entrance processing is performed by the entrance toll booth device 2A, the exit processing by the exit toll booth device 3A allows the vehicle's onboard device 5 to receive the centrally calculated toll calculated based on the basic toll table and the variable toll table. Also, when entrance processing is performed by the entrance toll booth device 2B, the exit processing by the exit toll booth device 3A allows the vehicle's onboard device 5 to receive the centrally calculated toll calculated based on the basic toll table, or the centrally calculated toll calculated based on the basic toll table and the variable toll table.

According to the first to fourth embodiments described above, it is possible to provide an ETC system compatible with central calculation for realizing toll calculation by the central device 1. The ETC system compatible with central calculation according to the first to fourth embodiments can appropriately collect tolls regardless of the combination of the entrance toll gate device 2A compatible with central calculation, the entrance toll gate device 2B compatible with exit calculation, the exit toll gate device 3A compatible with central calculation, and the exit toll gate device 3B compatible with exit calculation.
Therefore, even during the transition period in which the exit calculation-compatible entrance toll gate equipment 2B is gradually replaced with the central calculation-compatible entrance toll gate equipment 2A, and the exit calculation-compatible exit toll gate equipment 3B is gradually replaced with the central calculation-compatible exit toll gate equipment 3A, the central calculation-compatible ETC system can collect tolls appropriately.
