Send at a predetermined time interval with strength. When the vehicle enters the receivable area of the ID code confirmation signal, the vehicle-mounted device 100 receives the ID code confirmation signal by the transmission / reception antenna 4 and makes a pass permission judgment of the vehicle passage gate previously stored in the IC card 50. For I
The D code is transmitted to the roadside device 200 via the transmitting / receiving antenna. When the roadside device 200 receives the ID code transmitted from the vehicle-mounted device 100, the roadside device 200 collates whether or not this ID code matches a pre-registered ID code, and gives a passage permission to the vehicle only when the ID code matches. .

FIG. 10 is a table configuration diagram of an ID code registration table stored in the RAM of the IC card 50 or the ROM of the vehicle-mounted device section 1. As illustrated, the coordinates (latitude / longitude information) at which the vehicle passage gate is located and the corresponding ID code are stored as a set. In particular,
Vehicle passage gate information for lines other than toll roads is stored in lines 0 to (C-1), and toll gates or check barrier information on toll roads are stored in lines C and thereafter.

FIG. 11 is a flow chart showing the ID code processing of the second embodiment performed by the CPU 8 of the in-vehicle device section 1. When the ignition key is operated to the ON position and the main switch of the vehicle-mounted device 100 is turned on, the CPU 8 reads the program of FIG. 11 from the ROM 11 and executes it.

In step S101 of FIG. 11, the current vehicle position information (latitude / longitude information: Xc, Yc) detected by the navigation device 21 is read. Step S102
Then, it is determined whether or not the vehicle is on the toll road based on the processing result of step S101. If the vehicle is on a toll road, the process proceeds to step S103, and the IC card 5
0 of the RAM 53 or the ROM 11 of the in-vehicle device section 1 is referred to, starting from the line C of the ID code registration table of FIG. 10, the ID code corresponding to the vehicle position detected by the navigation device 21 is read, and the ID I for transmitting the code from the vehicle-mounted device 100 to the roadside device 200
It is stored in the RAM 10 of the vehicle-mounted device 100 as a D code. In step S104, the processes of steps S1 to S10 of the cash voucher switching process of FIG. 7 described above are performed. That is,
When a vehicle passes through an interchange registered in advance, the ID code is transmitted to the roadside device 200 to perform ID verification, and if the verification is successful, the IC card 50 pays the fee.

On the other hand, if the determination in step S102 is negative, that is, if the vehicle is not on the toll road, the process proceeds to step S105, where it is stored in the 0th and 1st columns of the ID code registration table of FIG. The vehicle position information (latitude / longitude information Xi, Yi or XICi, YICi) present is read in order from the top data. In step S106, the vehicle position information read sequentially from the ID code registration table and the vehicle current position (X
c, Yc) and the distance Li is calculated.

In step S107, the calculated distance Li
The smallest value is selected and the vehicle position corresponding to that value Li is detected. In step S108, it is determined whether or not the minimum value Li of the distance is less than or equal to a predetermined value. If it is greater than the predetermined value, the process returns to step S101, and if it is less than the predetermined value, the process proceeds to step S109. In step S109, the ID code corresponding to the vehicle position having the minimum value Li is selected from the ID code registration table, and this ID code is selected by the roadside device 2

When the process of step S104 or S109 is completed, the process proceeds to step S110, it is determined whether or not the ignition key is turned off, the vehicle is stopped because it is turned off, and the navigation device and the in-vehicle device 100 are also turned off. If so, the ID code is stored in a non-volatile memory, such as an EEPROM, and the process ends.

As described above, in the second embodiment, since various ID codes are stored in the IC card 50 in association with the vehicle position, not only can tolls for toll roads be collected but also parking lots and parking lots can be collected. It can also be used to manage gates for companies and garages. That is, it is possible to enter and exit the gates at a plurality of locations without replacing the IC card 50 and without entering the ID code. Further, since it is not necessary to carry a plurality of IC cards 50, the IC cards 5
There is no risk of mistaken 0, theft or loss.

-Third Embodiment- The third embodiment is a modification of the second embodiment. In step S109 of FIG. 11, when the ID code corresponding to the vehicle position detected by the navigation device is stored in the RAM 53 inside the IC card 50, the ID code is once mounted on the vehicle as the ID code to be transmitted to the roadside device 200. Although it is stored in the RAM 10 of the device unit 1, instead of the RAM 10 of the vehicle-mounted device unit 1, a specific storage area of the RAM 53 inside the IC card 50 or a magnetic stripe 56 of FIG. 2 provided in the IC card 50. It may be stored in any auxiliary recording medium.

In this way, the user can use the IC card 5
When 0 is removed from the in-vehicle device 100 and ID verification is performed outside the vehicle, the ID verification can be performed by the ID code stored in the specific storage area of the RAM 53 inside the IC card 50 or the magnetic stripe 56. The time required can be shortened. That is, by separately selecting the ID code used for ID verification and storing it in another storage area or storage medium separately from the RAM 53 inside the IC card 50 in which a plurality of ID codes are stored, the ID verification is performed. In this case, it is possible to save the trouble of selecting the ID code from the RAM 53.

-Fourth Embodiment- In the fourth embodiment, the power supply is restricted based on the vehicle position detected by the navigation device to reduce the power consumption. Since the fourth embodiment has the same structure as the first to third embodiments, the description of the structure will be omitted below.

FIG. 12 is a timing chart for explaining the battery save processing by the power control device.
(A) is a CPU peripheral circuit (CPU8, ROM11, RA
M10, IC card 50 read / write control circuit 20, etc.)
A conventional example in which a power supply voltage is intermittently supplied to components other than the above (dashed-dotted line part in FIG. 1), and FIG. The conventional example which gradually shortens the supply time is shown.

The battery save processing as shown in FIGS. 12 (a) and 12 (b) is effective when the calling signal is generated irregularly, but in the automatic toll collection device, the roadside device 200 to the in-vehicle device 100 are used. The position at which the call signal is transmitted is predetermined, and it is meaningless to periodically supply the power supply voltage as shown in FIGS. 12 (a) and 12 (b). For this reason, in the fourth embodiment, the power supply voltage is supplied to the entire vehicle-mounted device 100 only when the vehicle approaches the roadside device 200 as shown in FIG. 12C, and unnecessary power is not consumed inside the vehicle-mounted device 100. It was done like this.

FIG. 13 is a flow chart showing the ID code processing of the fourth embodiment performed by the CPU 8 of the vehicle-mounted device section 1. In the following, differences from the ID code processing of the second embodiment shown in FIG. 11 will be mainly described.

If it is determined in step S202 in FIG. 13 that the vehicle is not on the toll road, the process proceeds to step S203.
The supply of the power supply voltage to the circuits other than the CPU peripheral circuit (the one-dot chain line in FIG. 1) is stopped. Then, steps S204 to S20
8, the same processing as steps S105 to S109 in FIG. 11 is performed. If the ID code corresponding to the vicinity of the current position of the vehicle is stored in the IC card 50, the ID code is prepared to be transmitted, and step S
At 209, the power supply voltage is supplied to the entire in-vehicle device 100.

On the other hand, if it is determined in step S201 that the vehicle is on the toll road, step S211 in FIG.
The battery save process shown in (a) or (b) is performed.
As a result, the power supply voltage is intermittently supplied to the in-vehicle device 100 while traveling on the toll road. After that, the vehicle is the roadside device 2
Only when approaching 00, the power supply voltage is supplied to the entire vehicle-mounted device 100.

As described above, in the fourth embodiment, when communication is not performed with the roadside device 200, the power supply voltage is supplied only to the CPU peripheral circuit and the interface portion of the IC card 50, while the navigation is performed. The distance between the vehicle position information from the device and the position information of the roadside device 200 stored in the RAM of the IC card 50 is always calculated.
Then, when the distance becomes shorter and the communication between the vehicle-mounted device 100 and the roadside device 200 becomes possible, the power supply voltage is supplied to the entire vehicle-mounted device 100 including the one-dot chain line portion in the figure. By the above processing, the power consumption inside the vehicle-mounted device 100 can be efficiently reduced.

-Fifth Embodiment- In the fifth embodiment, after the recommended route from the starting point to the destination is calculated by the navigation device, the ID code registered on the toll road or the IC card 50 on the recommended route. Is detected, and if such a place exists, is the IC card 50 connected to the vehicle-mounted device 100 in advance before starting communication with the roadside device 200? It is to confirm whether or not.

That is, when the CPU of the vehicle-mounted device section 1 determines that there is a point on the recommended route where the information of the IC card 50 needs to be read, the CPU of the vehicle-mounted device 100 has the IC card 50.
IC card 5 to check whether or not is connected
Communicate with 0.
