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

In addition, in the second billing table 36, as described above, an amount of money is registered corresponding to the vehicle model, and an amount collected when entering the extended billing target area B, and when not entered, is collected. Road usage fee is registered by dividing by amount to say. For example, in a medium-sized vehicle, $ 0.5 is entered when entering the extended charging area B, and $ 1 when not entering. In this way, a benefit amount can be given to the driver of the vehicle 1 which has passed through the extended charging target area B by changing the amount of money differently when entering the extended charging target area B and when not entering. .

The entry determination unit 38 determines that the extended charging target area B has entered when the entry flag received from the on-board machine 20 is set, and when the entry flag is cleared, the entry charging unit 38 determines the extended charging target area B. ), And the result of the determination is output to the amount determining unit 39 (step SA3 in Fig. 8). The price determining unit 39 determines the vehicle model of the vehicle 1 based on the vehicle information received from the onboard device 20. Then, the road fee is determined in accordance with the vehicle type and the presence or absence of entry into the extended charging target area B (step SA4 in Fig. 8). For example, if the vehicle is medium-sized and enters the extended billing area B, $ 1 is extracted from the first billing table and $ 0.50 is extracted from the second billing table. Calculated as Then, the calculated road use fee is transmitted to the onboard device 20 via the first antenna 5 (step SA5 in FIG. 8).

The control unit 26 of the onboard vehicle 20 transmits a positive signal indicating completion of communication to the first antenna 5 when the road charge is received through the communication unit 27 (step SA6 in Fig. 8) and the IC card. The balance of the IC card is updated by subtracting the road usage fee from the balance of the balance (step SA7 in FIG. 8). Subsequently, when the balance updating process can be performed normally, the controller 26 reads the updated balance and authenticator data from the IC card (step SA8 in Fig. 8).

Next, upon receiving the inquiry signal issued from the second antenna 6 (step SB1 in FIG. 10), the control unit 26 transmits the vehicle information, the IC card information, the IC card balance, and the authenticator data to the communication unit 27. (Step SB2 in Fig. 10). Here, the authenticator data is information for notifying that the charge collection is normally performed.

When the second antenna controller 12 receives the authenticator data through the second antenna 8, the second antenna controller 12 transmits a confirmation command through the second antenna 8 (step SB3 in Fig. 10). When the control unit 26 of the on-board machine 20 receives this confirmation command, it transmits an acknowledgment signal through the communication unit 27 (step SB4 in Fig. 10) and writes the usage history to the IC card (Fig. 10). Step SB5). Subsequently, the control unit 26 clears the entry flag in the storage device 25 (step SB6 in FIG. 10), and ends the communication process.

In addition, you may carry out the transmission and reception of the information performed between the on-board device 20 and the 2nd antenna 8 mentioned above using a well-known encryption method. By performing communication using an encryption method, fraudulent acts such as alteration or eavesdropping of information can be prevented. Examples of the encryption method include AES for encrypting using a common key, RSA for encrypting using a public key and a secret key, and the like. In particular, since the authenticator data is important information for notifying that the toll collection has been normally performed, the reliability of the toll collection can be improved by encrypting and transmitting the authenticator data.

As described above, according to the toll collection system according to the present embodiment, in the on-vehicle device 20, the position information and the storage device 25 by the GPS receiver 24 have entered the extended charging target area B. FIG. It is detected based on the map information stored in. Thereby, in the case where the billing target area A is expanded, in other words, even when the extended billing target area B is newly established, the extended billing target area B is not installed at the boundary of the billing extension area B. Entry into B) can be detected reliably.

In addition, by the one charge collection device 2 provided in the charging target area A, the charge collection for both the extended charging target area B and the charging target area A can be performed.

Thereby, since it is not necessary to newly install the toll collection apparatus 2 in the extended charging target area B, installation cost can be reduced. As a result, it is possible to easily establish the extended charging target area B. FIG.

In addition, the entry flag once set is when the vehicle 1 enters the billing target area A, and when a series of communication processes relating to the toll collection performed between the toll collection device 2 described later is normally completed. It is set not to clear until now. Therefore, even after entering the extended charging target area B as shown in Fig. 11, even when the extended charging target area B is exited without entering the charging target area A, the set entry flag is not cleared. Do not. That is, the set entry flag is not cleared only by exiting the extended charging target area B. FIG. As a result, when the billing area A enters the billing area A next time, the record of entering the billing area B that has been extended remains, so it is reliably collected about the road fee in the billing area B that is extended. It becomes possible.

Instead of the entry flag, a counter for counting the number of times of entering the extended charging target area B may be provided. As a result, as shown in FIG. 11, when the vehicle 1 does not enter the charging target area A but enters the extended charging target area B many times, the vehicle 1 enters the charging target area A. At this time, it becomes possible to collect road use charges in accordance with the number of times the entry into the extended charging target area B so far.

In addition, by using the above entry flag instead of such a counter, it is possible to enter and exit the extended billing area B many times with a single road use fee. have.

In addition, in step SA2 shown in Fig. 8, the vehicle information, IC card information, IC card balance, information indicating the presence or absence of the GPS receiver 24 in addition to the state of the entry flag, for example, a vehicle-mounted version, is displayed. You may transmit to the 1st antenna 5 from the mounting apparatus 20. FIG. In this way, by transmitting the on-board version, it is possible to determine in the toll collection apparatus 2 whether or not the GPS receiver 24 is provided.

In the toll collection system according to the present invention, it is determined based on the positional information acquired by the GPS receiver 24 as to whether or not the vehicle 1 has entered the extended charging target area B. FIG. For this reason, in the vehicle-mounted device which is not equipped with the GPS receiver 24, since the present position of one cannot be identified, it cannot be judged whether it entered into the extended charging target area B, and therefore, the extended charging target It becomes impossible to collect road use charges about the area B.

Accordingly, by varying the amount of money collected by the toll collection system 2 according to whether or not the GPS receiver 24 is mounted, the vehicle and the GPS receiver 24 equipped with the vehicle-mounted vehicle which is not equipped with the GPS receiver 24 may be replaced. The balance of the collection charge between the vehicle 1 equipped with the onboard vehicle 20 provided is maintained. In particular, as shown in Fig. 12, when the vehicle 1 'equipped with the onboard vehicle that is not equipped with the GPS receiver 24 is provided with a higher road usage fee (for example, the GPS receiver 24 is provided). 2 times), it is possible to promote the supply of the vehicle-mounted device 20 equipped with the GPS receiver 24.

In the toll collection system according to the present embodiment, when toll collection is normally performed at the entrance of the area to be charged A, authentication information indicating that the charge is collected from the toll vehicle 2 to the on-vehicle device 20. In addition, the random number may be displayed on the display unit 28 of the vehicle-mounted device 20. In this way, the authentication information indicating the effect is displayed on the display unit 28 of the on-board machine 20 with respect to the vehicle on which the toll collection is normally performed. For example, a watchman or the like who monitors the road confirms the display. A fraudulent vehicle can be easily identified. The authentication information is not particularly limited, but may be a predetermined random number, for example. Instead of the display, for example, a light emitting element such as an LED may be turned on.

Next, the toll collection system according to the second embodiment of the present invention will be described.

The toll collection system according to the present embodiment differs from the first embodiment described above in that a plurality of extended charging target areas are set. Hereinafter, description is abbreviate | omitted about the point collection system which concerns on this embodiment in common with 1st Embodiment, and only a different point is demonstrated.

As shown in FIG. 13, when a plurality of extended charging target areas B1 and B2 are set, as shown in FIG. 14, the storage device 25a of the on-vehicle unit 20a stores each extended charging target area ( Map information of B1, B2 and identification information (b1, b2) assigned to each of the extended charging target areas B1, B2 are stored in association with each other, and the entry corresponding to each of the extended charging target areas B1, B2 is also stored. Flags F1 and F2 are registered.

As shown in Fig. 15, the storage device 37a of the first antenna controller 9a of the toll collection device includes the first charging tables 35a and 35b related to the extended charging target areas B1 and B2 and the respective charge charging tables 35a and 35b. Identification information (b1, b2) assigned to the extended charging target areas (B1, B2) is associated and stored.

13 to 15, when the vehicle 1 enters the extended charging target area B1, the control unit 26a of the on-board machine 20a stores the information received by the GPS receiver 24 and the storage device 25a. The vehicle 1 detects that the vehicle 1 enters the extended charging target area B1 on the basis of the map information stored therein, and sets a flag F1 corresponding to the extended charging target area B1. Subsequently, when the vehicle 1 enters the extended charging target area B2, the control unit 26a detects this effect and sets a flag F2 corresponding to the extended charging target area B2. Subsequently, when entering the charging target area A, the control unit 26a of the on-board machine 20 transmits the vehicle information, the state of the entry flags F1 and F2, etc. to the toll collection device through the communication unit 27. do.

In the first antenna controller 9a, when the vehicle information, the state of the entry flags F1, F2, and the like are received, the entry determination unit 38a extracts the set flags F1, F2, and extracts the extracted flag F1. , The identification information (b1, b2) of the extended charging target areas (B1, B2) corresponding to F2 is output to the amount determining unit 39a.

The amount determining unit 39a refers to each of the first charging tables 35a and 35b associated with the identification information b1 and b2 obtained from the entry determining unit 38a in the extended charging target areas B1 and B2. The road usage fee in the billing target area A is obtained with reference to the second billing table 36. And the road usage fee for the vehicle 1 is calculated by adding these amounts. Then, the road fee is transmitted to the onboard vehicle 20a via the first antenna 5.

When the control unit 26a of the on-board machine 20a receives the road usage fee through the communication unit 27, the control unit 26a subtracts the road usage fee from the balance recorded on the IC card, and updates the balance as the balance on the IC card. do. The details of the communication between the first antenna controller 8a and the on-vehicle device 20a are performed in accordance with the processing procedure shown in FIG.

As described above, according to the toll collection system according to the present embodiment, when a plurality of extended charging target areas are set, an entry flag corresponding to each extended charging target area is provided, and the state of each of these entry flags is different. Corresponding to the identification information of the extended charging target area and transmitted from the on-board device 20a to the first antenna controller 9a, the toll collection device side can easily specify the extended charging target area to which the vehicle has entered. Thereby, the road use fee in the extended charging target area which the vehicle entered can be determined early.

In addition, in the storage device 37a of the first antenna controller 9a, the first charging tables 35a and 35b are registered in correspondence with the respective extended charging target areas B1 and B2, so that detailed charges are provided for each extended charging target area. Setting can be performed. Further, even when the vehicle enters a plurality of extended charging target areas, charge collection can be performed collectively.

As shown in FIG. The plurality of extended charging target areas may be set adjacent to each other.

[Third Embodiment]

Next, the toll collection system according to the third embodiment of the present invention will be described.

The toll collection system according to the present embodiment differs from the toll collection system according to the first embodiment described above in that the road use fee of the extended charging target area B is determined according to the stay time.

Hereinafter, the description of the points common to the first embodiment of the toll collection system according to the present embodiment will be omitted, and only different points will be described.

As shown in Fig. 16, the on-vehicle machine 20b according to the present embodiment further includes a timer (timer) 32 for counting the stay time in the extended charging target area B. As shown in Figs. In addition, in the 1st antenna controller 9b which concerns on this embodiment, in the 1st antenna controller 9 shown in FIG. 9, the 1st charging table 35 with which the memory | storage device 37 is equipped has a parameter of a stay time. It is a billing table which I did (not shown).

As shown in Figs. 16 and 17, when the vehicle 1 enters the extended charging target area B, the control unit 26b of the on-board machine 20b detects that the extended charging target area B has entered. The timer 32 is activated at the same time the entry flag is set. As a result, the staying time in the extended charging target area B is counted by the timer 32. Subsequently, when entering the billing target area A, the control unit 26b of the on-board machine 20b receives the stay time indicated by the timer 32 in addition to the vehicle information through the communication unit 27 with respect to the toll collection device. Send. For example, when the control unit 26b receives an inquiry signal from the first antenna 5 of the toll collection device, the control unit 26b stops the operation of the timer 32 and reads the stay time at this time and transmits it to the toll collection device. do.

In the first antenna controller 9b of the toll collection device, it is detected by the entry determination unit 38 that the entry to the extended charging target area is notified to the price determining unit 39. The amount determining unit 39 calculates the road use fee according to the staying time for the extended charging target area B using the first charging table 35 represented as a function of the staying time, and at the same time the second billing table ( From 36), the road usage fee of the charging target area A corresponding to the vehicle 1 is extracted, and these are added to calculate the road usage fee of the vehicle 1. Then, the determined road use fee is transmitted to the onboard vehicle 20b via the first antenna 5.

When the control unit 26b of the on-board machine 20b receives the road usage fee according to the staying time through the communication unit 27, the control unit 26b subtracts the road usage fee from the balance recorded on the IC card, and balances the balance on the IC card. As a result of updating and recording, the timer 32 is cleared. The details of the communication between the first antenna controller 8b and the on-vehicle device 20b are performed in accordance with the processing procedure shown in FIG.

As described above, according to the toll collection system according to the present embodiment, since the stay time in the extended billing area B is transmitted to the billing device, the toll collection device stays in the extended billing area B. It becomes possible to calculate the road fee considering the time.

Thereby, it can be set as the road use fee in which the use situation of the road was reflected a lot.

In the present embodiment, the timer 32 and the entry flag are used in combination, but the entry flag is used because the timer 32 can be recognized as having entered the extended charging target area B by the operation of the timer 32. You do not have to do.

In addition, although the timer 32 was employ | adopted as a part which detects a stay time, you may time the time of stay using the time data contained in GPS data acquired by the GPS receiver 24 instead.

In addition, in this embodiment, since the road use fee is determined according to the staying time in the extended charging target area B, for example, when the vehicle is parked in the parking lot existing in the extended charging target area B, the timer 32 is used. Time of stay by is done, and that much is reflected in road charge. Therefore, as shown in Fig. 18, the operation of the timer 32 is stopped in the period of parking in the parking lot C in the extended charging target area B. As shown in Figs.

In this case, for example, when an inquiry signal is received from the entrance antenna 40 provided at the entrance of the parking lot C, the control unit 26b of the on-board machine 20b stops the operation of the timer 32, The control unit 26b operates the timer 32 when a confirmation signal indicating that the parking lot fee has been received from the exit antenna 41 provided at the exit of the parking lot C is received. Thereby, since the timer 32 is stopped in the period parked in the parking lot C, it is possible to prevent the parking time from being included in the stay time.

In addition, in this embodiment, in order to prevent illegal acts, such as alteration and eavesdropping of information, you may encrypt the communication data including the stay time performed between the on-board machine 20d and the center machine 17. FIG.

[4th Embodiment]

Next, a toll collection system according to a fourth embodiment of the present invention will be described.

The fee collection system which concerns on this embodiment determines the road use fee according to the mileage in the extended charge area B, The fee concerning 3rd embodiment which determines the road use fee according to the stay time mentioned above. It is different from the collection system.

Hereinafter, the point which is common to 3rd Embodiment about the toll collection system which concerns on this embodiment is abbreviate | omitted, and only a different point is demonstrated.

As shown in Fig. 19, the onboard vehicle 20c according to the present embodiment is a travel distance integrator (traveling distance) that integrates the travel distance instead of the timer 32 of the onboard vehicle 20b according to the third embodiment. Integrated part) 33 is provided. The travel distance accumulator 33 accumulates the travel distance using information from the GPS receiver 24, the gyro 19, the vehicle speed pulses output from the vehicle 1, and the like mounted on the onboard vehicle.

In addition, in the 1st antenna controller which concerns on this embodiment, in the 1st antenna controller 9 shown in FIG. 9, the billing which the 1st charging table 35 with which the memory | storage device 37 is equipped as a travel distance was parameterized. It is a table.

19 and 20, when the vehicle 1 enters the extended charging target area B, the control unit 26c of the on-board machine 20c detects that the vehicle 1 has entered the extended charging target area B and sets an entry flag. At the same time, the travel distance accumulator 33 is operated. As a result, the travel distance in the extended charging target area B is accumulated by the travel distance accumulator 33. Subsequently, when entering the charging target area A, the control unit 26c of the on-board machine 20c collects the toll distance accumulated by the mileage accumulator 33 in addition to the vehicle information through the communication unit 27. Send to the device. For example, when the control unit 26c receives an inquiry signal from the first antenna 5 of the toll collection device 2, the control unit 26c stops the operation of the travel distance accumulator 33 and reads the travel distance at this time. To the toll collection device.

In the first antenna controller 9 of the toll collection device, it is detected by the entry determination unit 38 that the entry to the extended charging target area is notified to the amount determining unit 39. The amount determining unit 39 calculates the road usage fee according to the traveling distance with respect to the extended charging target area B using the first charging table 35 represented as a function of the traveling distance, and at the same time, the second charging table. The road usage fee of the area to be charged A corresponding to the vehicle model of the vehicle 1 is extracted from 36, and the road usage fee of the vehicle 1 is calculated by adding them. Then, the determined road use fee is transmitted to the onboard vehicle 20c via the first antenna 5.

When the control unit 26c of the on-board machine 20c receives the road usage fee according to the travel distance through the communication unit 27, the control unit 26c subtracts the road usage fee from the balance recorded on the IC card, and the balance is added to the IC card. As a result of updating and recording, the value of the travel distance accumulator 33 is cleared. The details of the communication between the first antenna controller and the on-vehicle device 20c are performed in accordance with the processing procedure shown in FIG.

As explained above, according to the toll collection system which concerns on this embodiment, since the traveling distance in the area to be extended billing is transmitted to a toll collection device, a toll collection device is traveling in the area to be extended billing B It becomes possible to calculate the road fee considering the distance.

Thereby, it can be set as the road use fee in which the use situation of the road was reflected a lot.

In the present embodiment, the traveling distance accumulator 33 and the entry flag are used in combination. However, since the driving distance accumulator 33 is activated, it is possible to recognize that the extended charging target area B has been entered. The entry flag does not have to be used.

In addition, in the present embodiment, in order to prevent misconduct such as alteration or eavesdropping of information, communication data including a travel distance between the on-board machine 20d and the center machine 17 may be encrypted.

[Fifth Embodiment]

Next, the toll collection system according to the fifth embodiment of the present invention will be described.

The toll collection system according to the present embodiment is intended for the billing target area A in which a certain amount of charges are collected only by entering a predetermined area such as road pricing.

In the present embodiment, the staying period in the billing target area A is set in consideration of a case in which the billing target area A is incorrectly entered or the billing target area A has been entered but immediately exited. If it is within the period, the points for the period of stay are returned to the user.

Hereinafter, the description common to the third embodiment of the toll collection system according to the present embodiment will be omitted, and only different points will be described.

As shown in Fig. 21, the onboard vehicle 20d according to the present embodiment includes a wide area communicator 34 in addition to the configuration of the onboard vehicle 20b according to the third embodiment. This wide area communication device 34 communicates with an external device as shown in Fig. 22, and is for connection with the center device 17 (see Fig. 2), which is an upper device of the toll collection device, for example. This wide area communication device 34 may be incorporated in the onboard vehicle 20d, or may be used by connecting a mobile communication terminal such as a mobile phone through a connection terminal provided in the onboard vehicle 20d.

21 and 22, the vehicle 1 enters the charging target area A, and the control unit 26d, the first antenna 5, and the second antenna 9 of the on-board vehicle 20d described above. When the series of processes regarding billing are finished, the control part 26d resets the value of the timer 32, and then operates the timer 32 again. As a result, the staying time in the charging target area A is displayed.

Subsequently, when the vehicle 1 exits the charging target area A, the control unit 26d of the onboard vehicle 20d detects this and stops the operation of the timer 32. Subsequently, by reading the clock time of the timer 32, the stay time in the billing target area A is obtained, and the stay time is correlated with the vehicle information and the like to the center unit 17 through the wide area communication device 34. Send. The center machine 17, upon receiving the stay time associated with the vehicle information or the like, determines the point corresponding to the stay time based on the reduction point table. 23 shows an example of the reduction point table. In Fig. 23, the horizontal axis represents the stay time, and the vertical axis represents the reduction point. In this way, the reduction point table is set so that the reduction point decreases as the stay time is longer in the period of the stay time is within Tmax. Although Fig. 23 shows a case in which the stay time and the reduction point are inversely related, this is an example and is not specified in this example. For example, as shown in FIG. 24, the stay time may be divided into several levels, and the reduction point may be set to change step by step according to each level.

Returning to Figs. 21 and 22, in the center machine 17, when the reduction point P1 corresponding to the stay time T1 is obtained based on the reduction point, the center machine 17 returns the reduction point with respect to the vehicle-mounted machine 20d. Send. The control unit 26d of the onboard vehicle 20d stores this reduction point in the storage device 25 when the reduction point is received through the wide area communication device 34. At this time, when the reduction point is already recorded in the storage device 25, the reduction point is updated and added by adding the reduction point P1 received this time to this reduction point.

Then, the control unit 20d receives information with the first antenna controller 9 performed when the vehicle 1 enters the billing target area A the next time. Together, the reduction point recorded in the storage device 25 is transmitted. As a result, in the first antenna controller 9, the road use amount is calculated by subtracting the amount corresponding to the reduction point.

As described above, according to the charge collection system according to the present embodiment, in the chargeable area A in which a certain amount of charges are collected at the time of entry regardless of the road usage situation such as road pricing, the chargeable area A Since the points according to the stay time in) are returned to the owner of the vehicle, the user or the like who has wrongly entered the billing target area A can be saved from the money surface.

In addition, in this embodiment, in order to prevent illegal acts, such as alteration and eavesdropping of information, you may encrypt the communication performed between the onboard machine 20d and the center machine 17. FIG. In addition, in order to prevent cheating that intentionally increases the reduction point by changing the onboard vehicle 20d, the center machine 17 transmits the reduction point and the vehicle information as a list to all the toll collection devices 2. You may get drunk. In this way, the toll collection device can confirm whether the reduction point transmitted from the onboard vehicle is valid. In this case, the information is transmitted through a public line, an internet network, or the like.

In addition, when the vehicle 1 is parked in a parking lot in the charging target area A, the parking time is prevented from being included in the stay time by stopping the operation of the timer 32.

In addition, in this embodiment, although the reduction point was decided according to the staying time in the billing target area A, although a reduction point is decided according to the travel distance in the billing target area A instead, do. In this case, it is sufficient to have a travel distance accumulator 33 (see FIG. 19) instead of the timer 32 in FIG. 21, and the control unit 26c at the same timing as the timing at which the timer 32 is operated. By operating the travel distance accumulator 33, the travel distance in the charging target area A is integrated.

[Other Application Examples]

In the above, the case where the toll collection system of the present invention is applied to road pricing has been described, but the present invention can also be applied to an ETC system. For example, as shown in Fig. 25, when the charging target area (the existing toll road) A is expanded, the vehicle payload 20 is used to enter the extended charging target area (the expanded toll road B). Is detected by the GPS reception 24 of &quot; In this case, the entrance flag is transmitted together with the vehicle information at the exit tollgate. Thereby, since the ETC system side can recognize that it entered the charging target area A from the extended charging target area B, the road use fee is calculated in consideration of the charge of the extended charging target area B. As shown in FIG.

In addition, as shown in FIG. 26, when entering from the charging target area A and exiting via the expansion charging area B, the GPS receiver 24 exits from the expansion charging area B. FIG. Detect. In this case, the fee is not paid because it is withdrawn from the billing target area A without passing through the exit tollgate. In such a case, the current road use history may be recorded on the IC card, and the unpaid road use history may be transmitted to the toll collection device installed at the exit toll booth next time. As a result, the road usage fee according to the current road use situation is also paid. Instead of such a payment method, a system may be constructed in which a road fee is automatically withdrawn from a bank account of a user registered in advance. In this case, when exiting from the billing target area A without passing through the exit tollgate, the wide area communicator 34 described above with respect to the center unit 17, which is the host apparatus after the exit of the extended billing target area B, is withdrawn. The road usage history of this time is transmitted through (see FIG. 21). Thereby, in the center machine 17, this road use fee is calculated and this amount is withdrawn automatically from a bank account or the like.

In addition, although the present position was detected using only the GPS receiver 24 in the above-described first to fifth embodiments, the vehicle speed detected by the vehicle speed sensor mounted on the vehicle 1 in addition to the information received from the GPS satellites. The current position may be detected using information from a pulse or a gyro of the onboard vehicle. By doing in this way, the precision of position detection can be improved further.

In addition, as shown in Fig. 27, when the vehicle 1 is traveling in a tunnel or the like, since the information from the GPS satellites cannot be received, even if the vehicle 1 enters the extended charging target area B, it can be detected. There will be no. In preparation for such a case, an antenna for notifying the on-board vehicle 20 that the extended charging target area B has entered the boundary of the extended charging target area B set at a position where communication with the GPS satellite is difficult. It is preferable to provide 45. At this time, when a plurality of extended charging target areas B are set, the identification information of the extended charging target areas B is also transmitted.

In addition, even in the parking lot in the extended billing area B or the extended billing area A, the entrance is detected using the GPS receiver 24, so even at the entrance of the parking lot in a position where communication with the GPS satellites is difficult. Similarly, it is preferable to provide the antenna 45. In this case, it is preferable to transmit the information for recognizing which parking lot has entered to the onboard vehicle 20.

In addition, a D-GPS system may be used to further improve the accuracy of position detection by the GPS receiver 24. In this case, the correction data may be received via the FM multiple station as shown in FIG. In this case, as shown in Fig. 29, an FM multiple receiver 53 is further provided in the on-board vehicle 20.

In the D-GPS system shown in FIG. 28, the D-GPS position correction data analyzed by the base station 50 is transmitted to the FM broadcast station 52 through the center station 51 of the FM broadcast station. The FM broadcasting station 52 provides the received D-GPS correction data by FM multicasting. The D-GPS correction data transmitted by the FM multiplexing broadcast is received by the FM multiplexer 53 mounted on the onboard vehicle 20, and the correction of the position information using the D-GPS correction data is performed by the GPS receiver 24. It is done in. Thereby, position detection precision can be improved further.

In addition, in this embodiment mentioned above, although the contact type IC card was demonstrated as an example, you may use a noncontact type IC card instead.
