You may also.

In the extended billing area B, the toll collection device is not provided in the entry lane and the exit lane at the area boundary like the billing area A described above. Instead, the in-vehicle is detected by the onboard vehicle mounted on the vehicle 3.

6 is a block diagram showing a schematic configuration of a vehicle mounting apparatus according to the present embodiment. As shown in FIG. 6, the onboard device 50 relates to position information from a power supply circuit 23, a first wide area communicator 32, and a GPS satellite connected to the vehicle power supply 21 and the internal battery 22. Of the GPS receiver (location information acquisition unit) 24 for acquiring information and detecting the current position, the on-board storage unit (memory unit) 25 for storing various kinds of information, the control unit 26, and the toll collection device 2. Communication unit 27 for communicating with first antenna 5, second antenna 8, etc., display unit 28, notification unit 29 such as buzzer, LED, IC card insertion unit 30 into which IC card is inserted And an IC card interface (shown as "IC card I / F" in FIG. 6) 31 provided in the IC card insertion unit 30, a correction unit 33, and a communication port 34. As shown in FIG.

In FIG. 6, various components, such as the GPS receiver 24, do not necessarily need to be built in the onboard vehicle 50. As shown in FIG. For example, each component should just be comprised in the state which can receive information. As an example, it is possible to take a configuration form in which a portable terminal device having a GPS function is connected via an external terminal and use the GPS function included in the portable terminal device as the GPS receiver 24.

The first wide area communicator 32 communicates with an external device and is communicatively connected to, for example, a center device 17 (see FIG. 2), which is an upper device of the toll collection device 2.

The power supply circuit 23 mainly controls the voltage supplied from the vehicle power supply 21 to a voltage suitable for the vehicle mounter 50, and supplies it to each part constituting the vehicle mounter 50. The built-in battery 22 is provided so that even if the power supply from the vehicle power supply 21 is cut off, power enough to perform communication is secured.

The in-vehicle storage device 25 stores map information of the extended charging target area B set in addition to the charging target area A. FIG. The map information of the onboard storage device 25 is stored in correspondence with the information on the installation position of the antenna provided in the toll collection device 2 and the identification information of the antenna.

The onboard storage device 25 includes vehicle information including vehicle owner information, vehicle model information, vehicle ID, and the like, current location information of the vehicle, identification information of the onboard vehicle, balance information read from the IC card, card information, and the like. The information required for the calculation of the billed amount described later and the determination of the fraudulent vehicle is stored. The current position information of the vehicle 3 is information indicating the current position of the vehicle 3 estimated by the control unit 26 based on the map information and the position information acquired from the GPS receiver 24.

The IC card inserted into the IC card insertion section 30 is, for example, a contact type IC card, and incorporates an IC chip on which a flash memory, an MPU, or the like is mounted. In addition to card information such as a card ID number, the IC card stores a balance, a history of use, and the like. The information recorded in the IC card can be read and written by the control unit 26 via the IC card interface 31.

In such a vehicle-mounted device 50, when the IC card is inserted into the IC card insertion unit 30, the control unit 26 reads the IC card information and the balance recorded on the IC card through the IC card interface 31. The balance is written to the on-board storage device 25 and the balance is displayed on the display unit 28 for a predetermined time (for example, about 10 seconds). When the control unit 26 can normally read the information from the IC card, the control unit 26 operates the notifying unit 29 to inform the user of the normal operation. Thereby, for example, when the notification part 29 was a buzzer, a buzzer sounds, and if it is an LED etc., it is notified that it is normal.

On the other hand, when the information cannot be read from the IC card, the control unit 26 notifies the user of the error by displaying the error on the display unit 28 and by operating the notification unit 29. Prompting for reinsertion of the IC card. In addition, the form of the notification by the notification part 29 differs from normal time and abnormal time.

When the control unit 26 acquires the request signal from the toll collection device 2, the control unit 26 reads the identification information and the vehicle information of the onboard vehicle 50 stored in the onboard storage device 25, and simultaneously converts them to the request signal. It outputs to the toll collection apparatus 2 as a response signal. When the control unit 26 acquires the request signal from the charge collection device 2, the information on the entry when the vehicle 3 enters the charging target area A from the extended charging target area B and / or the charging target area A Input and exit information, which is information of exiting when exiting from the extended charging target area B, is detected from the terminal B and output to the center unit 17 through the first wide area communication device 32. The control unit 26 outputs the current position information and the vehicle information used when the entrance and exit information is detected together with the entrance and exit information to the center machine 17.

As shown in FIG. 7, the center unit 17 includes a second wide area communication unit 18, a negative determination unit 19, and a calculation unit 20. The second wide area communication device 18 communicates with an external device, and is for, for example, communicating with the onboard vehicle. Although the second wide area communication device 18 is described as being built in the center device 17 in the present embodiment, the present invention is not limited thereto. For example, the second wide area communication device 18 includes a mobile communication terminal such as a mobile phone. It may be used by connecting via a connection terminal provided on the back panel).

The negative determination unit 19 acquires the vehicle from the on-vehicle device via the vehicle-mounted device obtained from the toll collection device 2 and the entry / exit information of the vehicle 3 based on the vehicle information and the second wide area communication device 18. Based on the entry / exit information in (3), it is determined whether or not the vehicle has performed the illegality (for example, correcting the route that has passed) (hereinafter referred to as "negative vehicle").

As shown in FIG. 8, the case where the toll collection apparatuses 2x, 2y, 2z are provided in the area boundary of the extended charging target area B and the charging target area A is demonstrated as an example. The negative determination unit 19 of the center machine 17 detects the response signal received by the toll collection device 2y from the vehicle 3 (for example, referred to as vehicle ID "C"), and the response signal. On the basis of this, it is detected that the user has left the billing area A through the charge collection device 2y. In this case, the negative determination unit 19 detects entry and exit information corresponding to the vehicle ID "C" among entry and exit information obtained through the second wide area communication device 18.

Here, since the entrance / exit information corresponding to the vehicle ID "C" acquired by the negative determination unit 19 through the second wide area communication device 18 is determined based on the actual vehicle position detected by the GPS, the negative plate is negative. The government 19 compares the vehicle position of the vehicle 3 of the vehicle ID "C" estimated from this entrance / exit information with the vehicle position based on the response signal acquired from the toll collection apparatus side. Based on the information acquired from both of the above-mentioned, it is determined whether the detected (estimated) vehicle position matches. If the result of the determination does not match (for example, the position of the toll collection device 2z is detected in the entry / exit information), the negative determination unit 19 returns the response signal output from the vehicle 3. Since the state of being incorrectly corrected or the like is estimated, it is determined that the vehicle of the vehicle ID "C" is an illegal vehicle.

In addition, the negative determination unit 19 determines whether the vehicle 3 is an illegal vehicle on the basis of whether or not the vehicle 3 includes the on-board unit 50 corresponding to the vehicle model, based on the response signal obtained from the toll collection device 2. Determine. For example, although the vehicle information indicates that the vehicle is "large", such as a truck, the information of the vehicle model detected from the identification information of the onboard vehicle is an actual vehicle model when the vehicle is "small" such as a light vehicle. It is determined that the vehicle is mounted with a vehicle different from that of the vehicle, and that the vehicle is a fraudulent vehicle.

As described above, the negation determination unit 19 outputs the determination result of whether the vehicle is an illegal vehicle to the calculation unit 20 as described above.

The calculation unit 20 calculates the billed amount to be charged to the vehicle user as the road usage fee of the user of the vehicle 3 on the basis of the obtained entrance / exit information. In addition, the calculation unit 20 calculates the billed amount based on the determination result of whether or not it is an illegal vehicle obtained from the negative determination unit 19. For example, the calculating part 20 calculates the billed amount which applied the privilege, such as a discount, with respect to the vehicle 3 determined not to be a fraudulent vehicle, and about the vehicle 3 determined as a fraudulent vehicle to a fraudulent vehicle. The registered amount is registered in the black list for recording the information, and the billed amount without applying the privilege such as a discount is calculated.

Specifically, the calculation unit 20 includes a black list 34 in which information about an illegal vehicle is registered, a first charging table (first charging information) 35 in which charging information regarding an extended charging target area B is registered, Based on the center machine memory | storage device 37 which stores the 2nd billing table (2nd billing information) 36 in which billing information regarding the billing target area A was registered, and the entry / exit information received from the onboard equipment 50 And a price determining unit 38 for determining the billed amount of the vehicle 3 on which the vehicle-mounted device 50 is mounted.

In the first charging table 35, for example, the amount collected according to the vehicle type (large, medium, small, etc.) is registered as the first charging amount. For example, $ 0.8 for small, $ 1 for medium, $ 2 for large.

As described above, in the second charging table 36, an amount corresponding to the vehicle model is registered, and an amount to be collected when entering the extended charging target area B, and an amount to be collected when not entering. The divided second billed amount is registered. For example, in a medium-sized vehicle, $ 0.5 is entered when entering the area to be charged for expansion, and $ 1 when not entering.

Thus, the vehicle which has passed through the area to be extended charging by setting the amount to which the privilege such as a discount according to a route or a distance is applied by setting the amount of money different from the case of entering into the area to be extended charging to and from the case of not entering. It can give a feeling that the cost is reduced for the driver of 3).

The correction unit 33 acquires the identification information of the antenna from the toll collection apparatus when passing through the vicinity of the toll collection apparatus, and estimates the position of the vehicle estimated based on the acquired identification information and the map information of the toll receiver and the GPS receiver. When the position of the vehicle 3 estimated based on the positional information obtained from the 24 does not coincide, the GPS receiver 24 based on the position of the vehicle 3 estimated from the acquired identification information of the antenna. Correct the positional information obtained from.

The communication port 34 is an interface for communicating with an external device, and can be connected to, for example, a wireless or wired communication medium. In the present embodiment, it is assumed that the communication port is connected to the issuing and repairing device in a wired network (for example, Ethernet (registered trademark)). The issuing maintenance device 35 is connected so that communication with the center machine 17 is possible, The medium for connecting so that communication with the center machine 17 is not specifically limited.

Next, the operation contents of the on-vehicle device 50 when the vehicle 3 enters the charging target area A after the vehicle 3 enters the extended charging target area B will be described with reference to FIGS. 6 and 9.

As shown in FIG. 9, the GPS receiver 24 of the onboard device 50 acquires the positional information regarding the present position from a plurality of GPS satellites while driving. When the GPS receiver 24 outputs the acquired positional information to the control unit 26, the control unit 26 stores the vehicle 3 on the basis of these positional information and the map information stored in the onboard storage device 25. The current position information is detected and stored in the onboard storage device 25. Subsequently, when the vehicle 3 passes through the vicinity of the toll collection device 2, the control unit 26 receives the request signal from the first antenna 5 of the toll collection device 2. The entry / exit information of the vehicle 3 is detected based on the current position information stored in 25).

For example, after the current positional information stored in the onboard storage device 25 is the "expansion charging target area B" and the request signal is received from the first antenna 5, the control unit 26 makes a new information. When the current positional information is detected as "charged area A", the vehicle 3 detects that "enter the chargeed area A from the extended billing area B" and sets this as entrance / exit information. In addition, for example, after the current position information stored in the on-board storage device 25 is "charged area A" and receives a request signal from the first antenna 5, the control unit 26 makes a new control. When the current positional information is detected as "expanded billing area B", it detects that the vehicle 3 "ejected from the billing area A to the extended billing area B", and sets this as entrance / exit information.

The control part 26 outputs the entrance / exit information (for example, "entering into the charge object area A from the extended charge object area B") detected in this way to the center machine 17 via the 1st wide area | region communication machine 32. do.

The center machine 17 determines the billed amount as a road fee to be collected from the user of the vehicle 3 on the basis of the entrance / exit information acquired through the second wide area communication device 18, and the information of the determined billed amount is loaded into the on-vehicle device. About 50. When the control unit 26 of the vehicle-mounted device 50 receives the billed amount information through the first wide area communicator 32, the controller 26 deducts an amount corresponding to the acquired billed amount information from the balance recorded on the IC card. The balance is updated and recorded on the IC card as the balance.

Next, the operation in the case where the above-described vehicle mounter 50 corrects the information of the position of the vehicle (vehicle mounter) will be described.

When the vehicle 3 passes through the vicinity of the toll collection device 2, identification information of the antenna is transmitted from the first antenna 5 installed in the toll collection device 2 to the onboard device 50. do. The control unit 26 of the vehicle-mounted device 50 reports the identification information of the antenna (for example, the first antenna 5) of the acquired toll collection device 2 and the map information read from the storage device 25. Output to the government 33. Since the map information corresponds to the information on the installation position of the antenna installed in the toll collection apparatus 2 and the identification information of the antenna, the correction unit 33 uses the vehicle based on the map information and the acquired identification information of the antenna. The first current position of the payload 50 is estimated.

Moreover, positional information is acquired from the GPS receiver 24 of the onboard vehicle 50, and the correction part 33 estimates the 2nd current position of the onboard vehicle 50 based on this positional information. In addition, the correction unit 33 compares the first current position and the second current position and, if there is a mismatch, corrects the second current position based on the first current position, thereby deciding from the GPS receiver 24. Correct the position information. Thereby, the positional precision which the onboard device 50 detects can be improved.

In addition, when the charge collection apparatus 2 is changed in the installation position by construction etc., or when the charge collection apparatus 2 is newly installed, it is the map stored in the memory | storage device 25 of the on-board 50. The positional information of the toll collection device 2 registered in the information becomes old information, and the positional information may not be corrected correctly. Therefore, before the position information is corrected, the onboard device 50 determines whether the map information included in the storage device 25 of the onboard device 50 is the latest information, and the latest map information is the vehicle. When not equipped in the mounting apparatus 50, it is preferable to acquire the latest map information.

For example, when it is determined whether the map information is the latest information, installation of an antenna such as a version number is included in identification information of the antenna (for example, the first antenna 5) of the toll collection device 2. New and old identification information of a position (for example, update information which shows what information is at what time) is included, and old and new identification information (update information) of the installation position of this antenna is carried out from the toll collection apparatus 2 side. It is determined whether or not the obtained case coincides with the case of reading from the map information. If it does not match, the onboard device 50 acquires the latest map information contained in the map information from the center machine. As described above, the latest map information may be acquired when not only the old and new identification information (update information) such as the version number is matched, but also when the acquired antenna identification information is not obtained from the map information.

In the above, when the in-vehicle device 50 acquires the latest map information, it was explained by downloading the entire map information provided in the center unit, but the present invention is not limited to this. For example, the on-vehicle unit 50 notifies the center unit of the positional information on the identification information of the antenna selected as the download target on the in-vehicle unit 50 side, and notifies the center unit from the whole map information. It is also possible to output only the information of the positional information corresponding to the identification information of the antenna. In this way, by receiving only the positional information corresponding to the identification information of the selected antenna between the center unit and the onboard device 50, the communication load between the center unit and the onboard device 50 can be reduced.

In addition, the on-vehicle device 50 may include at least one of a first wide area communicator 32, a dedicated narrow band radio (DSRC), and a issuing and maintenance device for enabling communication with a center unit other than the first wide area communicator. , The latest map information having the correct installation location information of the toll collection device 2 is downloaded. Thereby, the onboard device 50 can easily acquire the information which specifies the installation position of the toll collection apparatus 2 from a some path | route.

As explained above, according to the onboard device 50 and the toll collection apparatus 2 which concern on this embodiment, between the toll collection apparatus mounted in the vehicle 3 and installed in the toll booth of the area to be charged, A When the vehicle-mounted device 50 which receives the information regarding billing passes through the vicinity of the toll collection apparatus 2, it acquires identification information of the antenna of the toll collection apparatus 2 from the toll collection apparatus 2. When the identification information of the antenna is acquired in the onboard device 50, the vehicle (based on the installation position of the antenna of the toll collection device 2 included in the map information stored in the storage device 25 and the identification information of the antenna) 3) is estimated. The position of the vehicle estimated based on the identification information of the antenna acquired from the toll collection apparatus 2 and the position of the vehicle estimated from the position information acquired from the GPS receiver 24 are compared, and the position of the vehicle is in agreement. If not, the positional information obtained from the GPS receiver 24 is corrected. Thus, the position information acquired from the GPS receiver 24 when the position of the vehicle estimated from the toll collection apparatus 2 side and the position of the vehicle estimated from the GPS receiver 24 are not matched and matched. By correcting this, the accuracy of the positional information obtained from the GPS receiver 24 can be maintained.

The positional information indicating the installation position of the antenna of the map information in the present embodiment may be information indicating a relative position for obtaining the position of the vehicle based on the calculation, and information indicating an absolute position for specifying the position of the vehicle. It may be enough. In this way, the position of the vehicle can be reliably specified whether the information on the installation position of the antenna is a relative position or an absolute position.

[Modifications]

In the above embodiment, based on the update information (for example, the version number) of the identification information of the antenna, it is determined whether or not the map information included in the storage device 25 is up-to-date information. Although the latest map information was obtained by downloading from the outside, the acquisition method of the latest map information of the onboard 50 is not limited to this.

For example, the information on the installation position of the antenna may be included in the identification information of the antenna output from the toll collection apparatus 2. In this case, the onboard device 50 that has acquired the identification information of the antenna including the information on the installation position of the antenna is an antenna corresponding to the acquired identification information of the map information stored in the onboard storage device 25. Change the information of the installation location. Or based on a predetermined condition previously about the installation position of the antenna acquired with the identification information of the antenna, and the installation position of the antenna corresponding to the identification information of the antenna stored in the onboard storage device 25. The priority to be set may be set, and the map information may be updated based on the priority.

In this way, the on-vehicle device 50 side can shorten the time for comparing the update information of the antennas, and can quickly obtain the information on the installation position of the antennas.
