For example, $ 0.8 for a small model, $ 1 for a medium model, $ 2 for a large model, and so on.

 [0054] In the second billing table 36, as described above, the amount of money corresponding to the vehicle type is registered, and furthermore, the amount to be collected when entering the extended billing area B, Road usage fees are registered separately for the amount collected when power is not advanced. For example, in a medium-sized vehicle, $ 0.5 is registered when entering the extended billing area B, and $ 1 is registered when there is no entry. In this way, the driver of the vehicle 1 that has passed through the extended billing target area B can be obtained by making the amount of money different depending on whether or not it has entered the extended billing target area B. It can give a good feeling to

[0055] When the approach flag received from the vehicle-mounted device 20 is set, the approach determination unit 38 determines that the user has entered the extended billing target area B and has hesitated, and the entry flag is cleared. Determines that it has not entered the extended billing area B, and outputs the determination result to the money amount determination unit 39 (step SA3 in FIG. 8). The money amount determination unit 39 determines the vehicle type of the vehicle 1 based on the vehicle information received from the vehicle-mounted device 20. Then, the road usage fee is determined according to the type of vehicle and whether or not there is an entry into the extended charging target area B (step SA4 in FIG. 8). For example, if the vehicle type is medium and the vehicle has entered extended billing area B, 1 dollar is extracted from the first billing table and the second billing table power is also 0.5 dollars, and these are added. 1.5 dollars is calculated as the road usage fee. Then, the calculated road usage fee is transmitted to the vehicle-mounted device 20 via the first antenna 5 (step SA5 in FIG. 8).

 [0056] Upon receiving the road usage fee via the communication unit 27, the control unit 26 of the vehicle-mounted device 20 transmits an affirmative signal indicating the completion of communication to the first antenna 5 (step SA6 in FIG. 8), and the IC The IC card balance is updated by subtracting the road usage fee from the balance of the force (step SA7 in Fig. 8). Subsequently, when the balance update process can be normally performed, the control unit 26 reads the updated balance and authenticator data from the IC card (step SA8 in FIG. 8).

 [0057] Next, when the inquiry signal transmitted from the second antenna 6 is received (step SB1 in FIG. 10), the control unit 26 obtains vehicle information, IC card information, IC card balance, and authenticator data. It transmits via the communication unit 27 (step SB2 in FIG. 10). Here, the authenticator data is information for notifying that the toll collection has been normally performed.

 When the second antenna controller 12 receives the authenticator data via the second antenna 8, the second antenna controller 12 transmits a confirmation command via the second antenna 8 (step SB3 in FIG. 10). Upon receiving this confirmation command, the control unit 26 of the on-vehicle device 20 transmits an affirmative signal via the communication unit 27 (step SB4 in FIG. 10) and writes a usage history to the IC card (step SB in FIG. 10). Five). Subsequently, the control unit 26 clears the entry flag in the storage device 25 (step SB6 in FIG. 10), and ends the communication process.

Note that the information exchange between the vehicle-mounted device 20 and the second antenna 8 described above may be performed using a known encryption method. By using the encryption method for communication, it is possible to prevent fraudulent acts such as tampering and wiretapping of information. Examples of encryption methods include AES, which performs encryption using a common key, and RSA, which performs encryption using a public key and a private key. In particular, the authenticator data notifies you that the toll collection was successful. Because it is important information, the authenticity of the toll collection can be improved by encrypting and transmitting the authenticator data.

 [0060] As described above, according to the toll collection system according to this embodiment, the fact that the vehicle has entered the extension billing target area B is stored in the location information and the storage device 25 by the GPS receiver 24 in the vehicle-mounted device 20. It will be detected based on the stored map information. As a result,

 If billable area A is expanded, in other words, even if extended billable area B is newly established, entry into extended billable area B without installing new equipment at the boundary of extended billable area B It can be detected reliably.

 Furthermore, the charge collection device 2 installed in the chargeable area A can collect charges for both the extended chargeable area B and the chargeable area A.

 As a result, it is not necessary to newly install the fee collection device 2 in the extended billing target area B, so that the equipment cost can be reduced. As a result, it is possible to easily establish a new extended billing area B.

 [0061] Note that the set entry flag indicates that the vehicle 1 has entered the billing area A and that a series of communication processing related to toll collection performed with the toll collection device 2 described later has been completed normally. Until it is done, it is set not to be cleared. Therefore, as shown in FIG. 11, even if the user enters the extended chargeable area B and then leaves the extended chargeable area B without entering the chargeable area A, the set entry flag is not cleared. In other words, the set entry flag is not cleared only by leaving the extended billing area B. As a result, the next time you enter chargeable area A, there will be a record of the entry to extended chargeable area B, so even if you use the road fee in extended chargeable area B, it will be collected reliably. It becomes possible.

[0062] Further, instead of the entry flag, a force counter for counting the number of times of entry into the extended billing area B may be provided. As a result, as shown in Fig. 11, if vehicle 1 does not enter billing area A and enters and leaves extended billing area B many times, it enters billing area A. Depending on the number of times you have entered the extended billing area B It will be possible to collect road usage fees.

 In addition, by using the above-mentioned 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 usage fee. You can give a good feeling to.

 [0063] Further, in step SA2 shown in FIG. 8, in addition to the vehicle information, the IC card information, the IC card remaining amount, the state of the entry flag, the presence / absence of the GPS receiver 24 is notified. Information, for example, the in-vehicle device version may be transmitted from the on-vehicle device 20 to the first antenna 5. As described above, by transmitting the in-vehicle device version, it is possible to determine whether or not the toll collecting device 2 is equipped with the GPS receiver 24 for the following reason.

 In the toll collection system according to the present invention, whether or not the vehicle 1 has entered the extended billing area B is determined based on position information acquired by the GPS receiver 24. For this reason, in-vehicle devices that do not have a GPS receiver 24 cannot determine their own current position, and therefore cannot determine whether or not they have entered the extended billing area B. It will be impossible to collect road usage fees for Area B.

 [0065] Therefore, depending on whether the GPS receiver 24 is installed or not, the fee collection system 2 collects a different amount of money so that the GPS receiver 24 is installed and the vehicle-mounted device is installed. The balance of the collection fee between the vehicle and the vehicle 1 equipped with the vehicle-mounted device 20 equipped with the GPS receiver 24 is maintained. In particular, as shown in FIG. 12, for a vehicle Γ equipped with a vehicle that is not equipped with a GPS receiver 24, the road usage fee is further increased (for example, when the GPS receiver 24 is provided). By setting this to twice, the spread of the vehicle-mounted device 20 equipped with the GPS receiver 24 can be promoted.

[0066] Further, in the fee collection system according to the present embodiment, when the fee collection is normally performed at the entrance of the chargeable area A, authentication information indicating that fact is received from the fee collection device 2 in the vehicle. The random number may be transmitted to the device 20 and further displayed on the display unit 28 of the vehicle-mounted device 20. In this way, for vehicles for which toll collection has been performed normally, authentication information indicating that fact is displayed on the display unit 28 of the vehicle-mounted device 20. For example, monitoring for monitoring roads An employee confirms the display to prevent unauthorized vehicles. It can be easily distinguished. The authentication information is not particularly limited, but may be a predetermined random number, for example. Also, instead of displaying, for example, it may take a form such as lighting a light emitting element such as an LED.

[Second Embodiment] Next, a fee collection system according to a second embodiment of the present invention will be described.

 The fee collection system according to the present embodiment is different from the first embodiment described above in that a plurality of extended billing target areas are set. Hereinafter, the fee collection system according to the present embodiment will not be described with respect to the points common to the first embodiment, and only different points will be described.

 As shown in FIG. 13, when a plurality of extended billing target areas Bl and B2 are set, as shown in FIG. 14, the storage device 25a of the vehicle-mounted device 20a has each extended billing target area Bl, The map information of B2 and the identification information bl, b2 assigned to each extended billing area Bl, B2 are stored in association with each other, and the entry flags Fl, F2 corresponding to each extended billing area Bl, B2 are stored. Is registered.

 In addition, as shown in FIG. 15, the storage device 37a of the first antenna controller 9a of the toll collection device includes the first billing tables 35a and 35b for each extended billing area Bl and B2, and each extended billing target area Bl, The identification information bl and b2 assigned to B2 are stored in association with each other.

 In FIG. 13 to FIG. 15, when the vehicle 1 enters the extended billing area B1, the control unit 26a of the vehicle-mounted device 2 Oa stores the information received by the GPS receiver 24 and the storage device 25a. Based on the map information, it is detected that the vehicle 1 has entered the extended billing area B1, and the flag F1 corresponding to this extended billing area B1 is set. Subsequently, when the vehicle 1 enters the extended chargeable area B2, the control unit 26a detects this and sets a flag F2 corresponding to the extended chargeable area B2. Subsequently, when entering the billing target area A, the control unit 26a of the vehicle-mounted device 20 transmits the vehicle information, the state of the entry flag Fl, F2, and the like to the toll collection device via the communication unit 27.

[0070] When the first antenna controller 9a receives the vehicle information, the state of the approach flags Fl, F2, etc., the approach determination unit 38a extracts the set flags Fl, F2, and extracts the extracted flags. The identification information bl, b2 of the extended billing target areas Bl, B2 corresponding to Fl, F2 is output to the amount determination unit 39a.

 The amount determining unit 39a refers to the first billing tables 35a and 35b associated with the identification information bl and b2 acquired from the entry determining unit 38a to determine the road usage fee in the extended billing target areas Bl and B2. At the same time, the road usage fee in the charging target area A is acquired with reference to the second charging table 36. The road usage fee for vehicle 1 is calculated by adding these amounts. Then, this road usage fee is transmitted to the vehicle-mounted device 20a via the first antenna 5.

 When the control unit 26a of the on-vehicle device 20a receives this road usage fee via the communication unit 27, the balance power recorded in the IC card is subtracted from the above road usage fee, and the remaining amount is updated to the IC power card as a balance. Record. The details of the communication between the first antenna controller 8a and the vehicle-mounted device 20a are performed according to the processing procedure shown in FIG.

[0071] As described above, according to the toll collection system according to the present embodiment, when a plurality of extended billing target areas are set, the advance flag corresponding to each extended billing target area is set. Since the status of these entry flags is transmitted to the first antenna controller 9a from the in-vehicle device 20a in association with the identification information of each extended billing area, the vehicle enters the toll collection device side. The extended billing area can be easily identified. This makes it possible to determine the road usage fee in the extended billing area where the vehicle has entered.

 Further, in the storage device 37a of the first antenna controller 9a, the first charging tables 35a and 35b are registered corresponding to the respective extended charging target areas Bl and B2. Settings can be made. Furthermore, even if a vehicle enters a plurality of extended billing target areas, it is possible to collect tolls in a lump.

 In the present embodiment, the case where two extended charging target areas are set is described, but the number of extended charging target areas B is not limited. Further, a plurality of extended billing target areas may be set adjacent to each other.

[Third Embodiment] [0072] Next, a fee collection system according to a third embodiment of the present invention will be described. The toll collection system according to the present embodiment is different from the toll collection system according to the first embodiment described above in that the road usage fee of the extended billing target area B is determined according to the staying time.

 Hereinafter, the fee collection system according to the present embodiment will not be described with respect to the points common to the first embodiment, and only different points will be described.

 [0073] As shown in FIG. 16, the vehicle-mounted device 20b according to the present embodiment further includes a timer (timer) 32 for measuring the staying time in the extended billing area B. Further, in the first antenna controller 9b according to the present embodiment, in the first antenna controller 9 shown in FIG. 9, the first charging table 35 provided in the storage device 37 is a charging table using the staying time as a parameter. (Not shown).

 [0074] As shown in FIGS. 16 and 17, when the vehicle 1 enters the extended charging target area B, the control unit 26b of the vehicle-mounted device 20b detects that the vehicle has entered the extended charging target area B, and sets the entry flag. Set timer and start timer 32. As a result, the time spent in the extended billing area B is counted by the timer 32. Subsequently, when entering the chargeable area A, the control unit 26b of the vehicle-mounted device 20b records the vehicle information, etc. via the communication unit 27, and the stay time measured by the timer 32 to the toll collection device. To send. For example, when receiving 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.

 In the first antenna controller 9b of the toll collection device, the entry determination unit 38 detects that the vehicle has entered the extended billing area and notifies the amount determination unit 39 of it. The amount determining unit 39 uses the first billing table 35 represented by the function relating to the staying time to calculate the road usage fee according to the staying time for the extended billing target area B, and from the second billing table 36. The road usage fee for vehicle 1 is extracted by adding the road usage fee for chargeable area A according to vehicle 1 and added to these. The determined road usage fee is transmitted to the vehicle-mounted device 20b via the first antenna 5.

When the control unit 26b of the vehicle-mounted device 20b receives the road usage fee corresponding to the staying time via the communication unit 27, the balance power recorded in the IC card is subtracted from the above road usage fee, The remaining amount is recorded as a balance on the IC card and the timer 32 value is cleared. The details of the communication between the first antenna controller 8b and the vehicle-mounted device 20b are performed according to the processing procedure shown in FIG.

[0076] As described above, according to the charge collection system according to the present embodiment, the stay time in the extended charge target area B is transmitted to the charge collection apparatus. It is possible to calculate the road usage fee taking into account the staying time.

 Thereby, it can be set as the road use charge in which the use condition of the road was reflected more.

[0077] In the present embodiment, the timer 32 and the entry flag are used in combination.

Because the 1S timer 32 is activated, you can recognize that you have entered the extended billing area B, so do not use the entry flag!

 In addition, the power of adopting the timer 32 as a unit for detecting the stay time Instead of this, the stay time may be measured using the time data included in the GPS data acquired by the GPS receiver 24. .

[0078] In the present embodiment, since the road usage fee is determined according to the staying time in the extended billing target area B, the vehicle is parked in a parking lot existing in the extended billing target area B. If this happens, the time spent by the timer 32 will be counted, and the amount will be reflected in the road usage fee. Therefore, as shown in FIG. 18, the timer 32 is stopped during the parking period C in the extended billing area B.

 In this case, for example, when an inquiry signal is received from the entrance antenna 40 installed at the entrance of the parking lot C, the control unit 26b of the in-vehicle device 20b stops the operation of the timer 32,

 When a confirmation signal indicating that the parking fee has been received is received from the exit antenna 41 installed at the exit of the parking lot C, the control unit 26b activates the timer 32. This prevents the parking time from being included in the staying time because the timer 32 is stopped during the period when the parking lot C is parked.

In this embodiment, in order to prevent fraudulent acts such as tampering and wiretapping of information. The communication data including the staying time performed between the vehicle-mounted device 20d and the center device 17 may be encrypted.

 [Fourth Embodiment] Next, a fee collection system according to a fourth embodiment of the present invention will be described.

 The toll collection system according to the present embodiment is based on the third embodiment in which the road usage fee is determined according to the above-mentioned staying time in that the road usage fee is determined according to the travel distance in the extended charging target area B. Different from toll collection system.

 Hereinafter, the fee collection system according to the present embodiment will not be described with respect to the points common to the third embodiment, and only different points will be described.

As shown in FIG. 19, the on-vehicle device 20c according to the present embodiment replaces the timer 32 of the on-vehicle device 20b according to the third embodiment with a travel distance accumulator (travel distance integration) that integrates the travel distance. Part) 33. The mileage accumulator 33 accumulates the mileage using information such as the vehicle speed pulse output from the GPS receiver 24, the gyro 19, and the vehicle 1 installed in the vehicle-mounted device.

 Further, in the first antenna controller according to the present embodiment, in the first antenna controller 9 shown in FIG. 9, the first charging table 35 provided in the storage device 37 is a charging table using the travel distance as a parameter. RU

 In FIG. 19 and FIG. 20, when the vehicle 1 enters the extended charging target area B, the control unit 26c of the vehicle-mounted device 2 Oc detects that it has entered the extended charging target area B, and sets the entry flag. And the mileage accumulator 33 is activated. As a result, the travel distance in the extended billing target area B is accumulated by the travel distance accumulator 33. Subsequently, when entering the chargeable area A, the control unit 26c of the on-vehicle device 20c charges the travel distance accumulated by the travel distance accumulator 33 through the communication unit 27 in addition to the vehicle information and the like. Sent to the receiving 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 mileage accumulator 33 and reads the mileage at this time to collect the toll. Send to device.

In the first antenna controller 9 of the toll collection device, the entry determination unit 38 detects that the vehicle has entered the extended billing area and notifies the amount determination unit 39 of the entry. Amount determination section 39 calculates the road usage fee according to the travel distance related to the extended billing target area B using the first billing table 35 represented by the function related to the travel distance, and the vehicle type of the vehicle 1 from the second billing table 36. The road usage fee for vehicle 1 is calculated by extracting the road usage fee for chargeable area A according to the above and adding them together. The determined road usage fee is transmitted to the vehicle-mounted device 20c via the first antenna 5.

 When the control unit 26c of the in-vehicle device 20c receives the road usage fee according to the travel distance via the communication unit 27, the balance power recorded in the IC card is subtracted from the above road usage fee, and the remaining amount is stored in the IC card. It is updated and recorded as a balance, and the value of the mileage accumulator 33 is tared. The details of the communication between the first antenna controller and the vehicle-mounted device 20c are performed according to the processing procedure shown in FIG.

[0083] As described above, according to the toll collection system according to the present embodiment, the travel distance in the extended billing target area B is transmitted to the toll collecting device. It is possible to calculate the road usage fee in consideration of the travel distance.

 Thereby, it can be set as the road use charge in which the use condition of the road was reflected more.

[0084] In the present embodiment, the mileage accumulator 33 and the approach flag are used in combination. However, when the mileage accumulator 33 is activated, it has entered the extended billing area B. Because it can be recognized, do not use the entry flag.

 In this embodiment, in order to prevent unauthorized acts such as information tampering and eavesdropping, communication data including a travel distance between the vehicle-mounted device 20d and the center device 17 may be encrypted.

 [Fifth Embodiment] Next, a fee collection system according to a fifth embodiment of the present invention will be described.

 The toll collection system according to the present embodiment is intended for billing target area A where a certain amount of fee is collected just by entering a certain area, such as road pricing. .

In the present embodiment, the charging target area is considered in consideration of accidentally entering the charging target area A or entering the charging target area A but leaving immediately. When the stay period in A is within the prescribed period, the points corresponding to the stay period are returned to the user.

 Hereinafter, the fee collection system according to the present embodiment will not be described with respect to the points common to the third embodiment, and only different points will be described.

 As shown in FIG. 21, an in-vehicle device 20d according to the present embodiment includes a wide area communication device 34 in addition to the configuration of the in-vehicle device 20b according to the third embodiment. As shown in FIG. 22, the wide-area communication device 34 communicates with an external device. For example, the wide-area communication device 34 is connected to the center device 17 (see FIG. 2), which is a higher-level device of the toll collection device. It is. The wide area communication device 34 may be built in the in-vehicle device 20d, or may be used by connecting a mobile communication terminal such as a mobile phone via a connection terminal provided in the in-vehicle device 2 Od.

 In FIG. 21 and FIG. 22, the vehicle 1 enters the billing target area A, and further, a series of billing is performed between the control unit 26d of the vehicle mount 20d and the first antenna 5 and the second antenna 9 described above. When the above process is completed, the control unit 26d resets the value of the timer 32 and then operates the timer 32 again. As a result, the staying time in chargeable area A is timed.

 [0088] Subsequently, when the vehicle 1 leaves the chargeable area A, the control unit 26d of the vehicle-mounted device 20d detects this and stops the operation of the timer 32. Subsequently, by reading the time measured by the timer 32, the stay time in the chargeable area A is acquired, and this stay time is associated with the vehicle information and transmitted to the center device 17 via the wide area communication device 34. . When the center machine 17 receives the stay time associated with the vehicle information or the like, the center machine 17 determines a point corresponding to the stay time based on the return point table. Here, FIG. 23 shows an example of the return point table. In FIG. 23, the horizontal axis is the stay time, and the vertical axis is the reduction point. In this way, the return point table is set so that the longer the stay time is, the less the return points are during the stay time within Tmax. In Fig. 23, the force shows that the staying time and the return point are in an inversely proportional relationship. This is an example and is not specified in this example. For example, as shown in Fig. 24, the stay time is divided into several levels, and the reduction points are set to change step by step according to each level!

[0089] Returning to FIG. 21 and FIG. 22, the center machine 17 stays based on the return point. When the reduction point PI corresponding to the time Tl is obtained, the center machine 17 transmits the reduction point to the vehicle-mounted device 20d. When receiving the return point via the wide area communication device 34, the control unit 26d of the on-vehicle device 20d stores the return point in the storage device 25. At this time, if a return point has already been recorded in the storage device 25, the return point is updated and recorded by adding the currently received return point P1 to the return point. Then, in the next transfer of information with the first antenna controller 9 that is performed when the vehicle 1 enters the chargeable area A next time, the control unit 20d stores the storage device 25 together with information such as vehicle information and an entry flag. Send the redemption points recorded in. As a result, the first antenna controller 9 calculates the road usage amount by subtracting the amount corresponding to the return point.

 [0090] As described above, according to the toll collection system according to the present embodiment, a fixed amount of toll is collected at the time of entry regardless of road usage conditions such as road pricing. In the case of a billable area A, the user who accidentally entered the billable area A will be given back to the owner of the vehicle according to the time spent in the billable area A. Etc. can be saved in financial terms.

 In the present embodiment, communication performed between the vehicle-mounted device 20d and the center device 17 may be encrypted in order to prevent unauthorized acts such as information tampering and wiretapping. Also, in order to prevent unauthorized acts that intentionally increase the return points by falsifying the in-vehicle device 20d, the center device 17 lists the return points and vehicle information and sends them to all toll collection devices 2. It is also possible to take a method. By doing so, the toll collection device can confirm whether the return point transmitted from the vehicle-mounted device is valid. In this case, the information is transmitted via, for example, a public line or the Internet.

 [0092] Further, when the vehicle 1 is parked in the parking lot in the chargeable area A, the operation of the timer 32 is stopped to prevent the parking time from being included in the staying time. Can do.

Furthermore, in the present embodiment, the return point is determined according to the staying time in the billing target area A. Instead, the travel distance in the billing target area A is determined. It is good also as determining a reduction point according to. In this case, instead of the timer 32 in FIG. 21, the control unit 26c, which has only to have the mileage accumulator 33 (see FIG. 19),

 By operating the mileage accumulator 33 at the same timing as when the timer 32 is activated, the mileage in the chargeable area A is accumulated.

 [Other Application Examples] In the above, the power described in the case where the toll collection system of the present invention is applied to road pricing. The present invention can also be applied to an ETC system. For example, as shown in Fig. 25, when the chargeable area (existing toll road) A is expanded, the entry to the extended chargeable area (expanded toll road) B is detected by the GPS reception 24 of the in-vehicle device 20. And set the entry flag. In this case, an entrance flag is transmitted at the exit toll gate along with vehicle information. As a result, the ETC system can recognize that it has entered the billing target area A from the extended billing target area B, so the road usage fee is calculated in consideration of the charge in the extended billing target area B.

 [0094] Further, as shown in FIG. 26, when the user enters from chargeable area A and leaves via extended chargeable area B, the fact that extended chargeable area B power is also removed by GPS receiver 24. Is detected. In this case, you will leave the billing area A without going through the exit toll gate, so the fee remains unpaid. In such a case, record the current road use history on the IC card and send the unpaid road use history to the toll collection device installed at the exit toll gate next time. Good. As a result, the road usage fee according to the current road usage situation will also be paid. In addition, instead of such payment! It is also possible to construct a system that automatically deducts road usage fees such as bank accounts of users. In this case, if you leave the chargeable area A without passing through the exit toll gate, after leaving the extended chargeable area B, The current road use history is transmitted through the above-mentioned wide area communication device 34 (see FIG. 21). As a result, the center machine 17 calculates the current road usage fee, and this amount is automatically deducted from the bank account.

[0095] In the first to fifth embodiments described above, only the GPS receiver 24 is used. The force that detected the current position GPS satellite force In addition to the information received, the current position is determined using vehicle speed pulses detected by the vehicle speed sensor installed in the vehicle 1 and information from the gyroscope of the in-vehicle device. May be detected. By doing so, the accuracy of position detection can be further improved.

[0096] Further, as shown in FIG. 27, when vehicle 1 is traveling in a tunnel or the like, information from a GPS satellite cannot be received. Will not be able to detect it. In preparation for such a case, regarding the boundary of extended billing area B that is set at a position where it is difficult to communicate with GPS satellites, it is necessary to notify OBE 20 that it has entered extended billing target area B. The antenna 45 is preferably installed. At this time, if multiple extended chargeable areas B are set,

 The identification information for extended billing area B is also sent.

 [0097] In addition, in the parking area in the extended charging target area B or the extended charging target area A, since the approach is detected using the GPS receiver 24, it is difficult to communicate with the GPS satellite. Similarly, it is preferable to install the antenna 45 at the entrance of the parking lot. In this case, it is preferable to transmit information for recognizing which parking lot has entered to the vehicle-mounted device 20.

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

The D-GPS position correction data analyzed by the base station 50 in the D-GPS system shown in FIG. 28 is transmitted to the FM broadcast station 52 via the center station 51 of the FM broadcast station. . FM broadcast station 52 provides the received D-GPS correction data by FM multiplex broadcasting. The D-GPS correction data transmitted by FM multiplex broadcasting is received by the FM multiplex receiver 53 installed in the vehicle-mounted device 20, and the position information correction using the D-GPS correction data is performed by the GPS receiver 24. Done. Thereby, the position detection accuracy can be further improved.
