Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-vehicle device which is mounted on a vehicle while holding an IC card having a payment function in a detachable manner and performs toll collection processing by wireless communication with a roadside machine at a tollgate.

[0002]

2. Description of the Related Art In recent years, as an automatic toll collection system for toll roads, a vehicle-mounted device having a wireless communication function is mounted on a vehicle.
When a vehicle passes a tollgate, automatic toll collection processing is performed by wireless communication between the on-board unit and the roadside machine installed at the tollgate so that the vehicle can pass through the tollgate without stopping. A new system has been developed.

FIG. 5 schematically shows the above non-stop automatic toll collection system. As shown in the figure,
A vehicle 1 running on a toll road is equipped with an on-vehicle device 2 having a wireless communication function. Vehicle type information, amount information, and the like are written in advance in the on-vehicle device 2, and traffic route information, billing information, and the like are written when passing through a tollgate. The in-vehicle device 2 is an I-type device having a fee payment function.
The C card can be removed.

On the other hand, toll booths such as an entrance tollgate, a check barrier tollgate, and an exit tollgate are provided with a roadside device 4, for example, a roadside antenna 5 for transmitting and receiving signals to and from the on-vehicle device 2, and a roadside antenna. A roadside communication device 6 that performs communication via the communication device 5 and a roadside processing device 7 that processes data transmitted to and received from the vehicle-mounted device 2 are provided.

[0005] When the vehicle 1 equipped with the on-vehicle device 2 enters the toll booth, the on-vehicle device 2 performs radio communication with the roadside device 4 and transmits information necessary for toll collection to the roadside device 4. The roadside device 4 calculates a toll based on the information sent from the vehicle-mounted device 2, and transmits the result to the vehicle-mounted device 2. The vehicle-mounted device 2 writes the result sent from the roadside device 4 into the IC card, and ends the toll collection process.

[0006]

In the toll collection system for toll roads described above, when the prepaid system having the balance remaining on the IC card is paid, a withdrawal process is performed on the IC card. ,
In a check barrier toll booth, etc., it is necessary to record the route information such as the tollgate passage information in the IC card. However, the communication time between the vehicle-mounted device 2 and the roadside device 4 generally depends on the IC device. These recording processes need to be performed after the communication process between the vehicle-mounted device 2 and the roadside device 4 is completed because the recording process time for the card is short.

In order for the roadside device 4 to recognize that the recording processing on the IC card by the vehicle-mounted device 2 has been completed normally, a first communication area for collecting tolls is provided, and the roadside device 4 is provided in the vehicle traveling direction. It is necessary to take some measures such as providing a second communication area at a predetermined distance, inquiring the result to the vehicle-mounted device 2 after the recording process is completed, and stopping the vehicle 1 when the operation fails, In this case, it is conceivable to omit the second communication area as shown in FIG. 5 due to restrictions on the installation location or equipment costs.

When the second communication area is omitted, if the recording on the IC card fails, it is impossible to withdraw the toll or record the route information and the like. Should be tried.

[0009] Furthermore, it is considered that the cause of the failure in recording on the IC card is, for example, the most frequent contamination or poor contact of the contact points. In such a case, it can be improved by reinserting the IC card. Strong nature.

[0010] However, in the conventional vehicle-mounted device, if an error occurs during the recording process on the IC card, only "IC card error" is displayed, and even if the IC card is removed and reinserted, the error is not detected. The state is maintained and no retry is performed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem. Even when recording on an IC card has failed,
An object of the present invention is to provide an on-vehicle device capable of retrieving a failed recording process by retrieving the failed IC card by retrieving the IC card and reinserting the IC card so that the recording process can be made as successful as possible and achieving high reliability. And

The control unit 11 generally has a plurality of data buffer DBs for storing data (information) held by the vehicle-mounted device 2 and a plurality of data buffer DBs for reading and writing contents of the IC card 20. Also,
The control unit 11 includes a memory 17 for storing a recording abnormality flag for storing that a recording abnormality on the IC card 20 has occurred, an IC card ID having a recording abnormality, and a recording command for the abnormal IC card. have.

As shown in FIG. 2, the IC card 20 is constituted by a one-chip CPU and includes a plurality of internal memories 21 composed of nonvolatile memories. This internal memory 2
1 stores information for specifying an IC card, that is, IC card ID information, information necessary for payment, and entrance information, and generally, passage route information such as a plurality of check barrier passage information. The information required for the payment includes a payment ID (account number) in the postpaid method and a balance in the prepaid method.

Next, the operation of the above embodiment will be described. In this embodiment, a description will be given by taking as an example a charging process for a prepaid IC card 20 having a balance in the IC card 20 on a flat toll road.

[1. Processing when user inserts IC card into vehicle-mounted device] When recording abnormality flag stored in memory 17 of vehicle-mounted device 2 is off, ie, IC card 20
In a state where the recording process to the IC has not yet failed, the IC
When the card 20 is inserted into the vehicle-mounted device 2, as shown in FIG. 3, the vehicle-mounted device 2 transmits an IC card ID required for communication processing with the roadside device 4 (hereinafter, ID information read first from the IC card 20). IC card ID1), payment information (including the balance), and route information, and read out the data buffer DB.
And temporarily stored in the memory 17. In some cases, there is no route information, and in that case, the route information is not transferred. When the recording abnormality flag is on, the processing described later is executed.

[2. Processing at the time of communication in the lane] When the vehicle 1 enters the exit tollgate, the roadside device 4 detects the vehicle 1 and wirelessly communicates with the vehicle-mounted device 2 to execute the charging process shown in the flowchart of FIG. FIG. 4 is a flowchart showing a charging process for a prepaid IC card 20 on a flat toll road.

First, the roadside device 4 first stores in the memory 17 of the vehicle-mounted device 2.
Information, ie, IC card ID
1, the payment information recorded in the data buffer DB is read (steps A1 and A2), necessary checks such as a validity check of the payment are performed, and then a toll is calculated based on the separately obtained vehicle type information (step A3). ), A command to remove the toll amount from the balance of the IC card (hereinafter referred to as a removal command) is transmitted to the vehicle-mounted device 2 (step A4). As a method for acquiring the vehicle type information, there is a method in which the vehicle type information is recorded in the on-vehicle device 2 in advance and the road side device 4 reads the information, or a method in which the vehicle type information is measured by a road side system.

[3. Processing after communication in lane] OBE 2
Receives the removal command from the roadside device 4 (step A5), ends the communication processing with the roadside device 4 (step A5).
6) The retry counter c1 for reinsertion is set to "0", the transmission retry counter c2 for the removal command is set to "0" (steps A7 and A8), and the removal command including the toll amount is sent to the IC card 20. A transmission is made (step A9) and the IC card 20 is instructed to subtract the toll amount from the balance. At this time, the vehicle-mounted device 2 turns on the monitoring timer.

When the IC card 20 receives the withdrawal process from the on-vehicle device 2 (step A10), the internal memory 21
The toll amount specified is subtracted from the remaining balance held in the vehicle (step A11), and the result, that is, the normal removal completion or abnormality is transmitted to the vehicle-mounted device 2 (step A12). Is received or when the monitoring timer times out (step A13), it is determined whether or not the withdrawal result has been normally received (step A13).
14) If normal, display to user (step A15).

When the withdrawal command is transmitted to the IC card 20 in step A9, if the command is not correctly transmitted to the IC card 20 due to a contact failure of the IC card contact, or the content is erroneous. If sent, I
If there is no response from the C card 20 within a certain period of time (set time by the monitoring timer), or if a response indicating an abnormality is received from the IC card 20, etc., it is determined that the withdrawal command has not been correctly executed by the IC card 20. Can be recognized.

In such a case, the on-vehicle device 2 counts the transmission retry counter c2 to determine the IC of the withdrawal command until the predetermined maximum number c2max is reached.
The transmission to the card 20 is retried (step A16).

If the removal process is not successful even after the retry is performed a predetermined number of times, the vehicle-mounted device 2 increments the reinsertion retry counter c1 by "1" and checks whether the count value has reached the set maximum value. Is determined (step A17),
If the set maximum value has not been reached, the vehicle-mounted device 2 turns on the recording abnormality flag stored in the memory 17, stores the ID of the IC card in which the recording has failed, and the withdrawal command in the memory 17, and indicates that there is a recording abnormality. The display is displayed on the display unit 16 (step A18) to prompt the user to re-insert the same card. The in-vehicle device 2 stores in the memory 17 the removal command that was not successful at this time, the fact that the recording was not successful, and the IC card ID that became abnormal.

Next, the user inserts the IC card 20 into the vehicle-mounted device 2.
When, for example, the contact portion is cleaned and then inserted again into the same vehicle-mounted device 2, the vehicle-mounted device 2 detects the insertion of the IC card 20 (step A19), and the recording abnormality flag stored in the memory 17 turns on. It is checked whether it is on or not, and if it is on, the ID information of the inserted IC card 20 is read (hereinafter, the ID information read at the time of re-insertion is referred to as IC card ID 2) and stored in the memory 17. Check with the IC card ID1 that has become abnormal (step A
20). If the IC card ID1 and ID2 match,
Returning to step A8, the transmission retry counter c2 is set to "0".
After that, a removal command is transmitted to the IC card 20, and the retry processing is retried.

In this case, since the IC card 20 is once removed from the vehicle-mounted device 2 and re-inserted, if a recording error occurs due to poor contact of the contact, the situation is highly likely to be improved. There is a high probability that the recording process will succeed.

If the removal process succeeds due to the reinsertion of the IC card 20, a message indicating that the recording has been normally completed is displayed on the display unit 16 of the vehicle-mounted device 2 in step A15 as described above.

If the removal process is not successful even after the reinsertion of the IC card 20, after the retry of c2max times by the transmission retry counter c2, an indication of the recording abnormality is displayed again, and the same as above. Repeat the above operation.

If the repetitive operation by reinsertion is not completed, the vehicle-mounted device 2 cannot perform other communication processing. Therefore, the number of trials by reinsertion of the IC card 20 is counted by the reinsertion retry counter c1. When the reinsertion retry counter c1 reaches a predetermined number of c1max times, the retry operation of recording retry by reinsertion is terminated,
The recording error flag stored in the memory 17 is turned off, the ID of the IC card in which the recording error has occurred, and the withdrawal command are deleted, and the display unit 1 indicates that retry by reinsertion is completed.
6 (step A21), and returns to the initial state.

As described above, the vehicle-mounted device 2 includes the IC card 20
Even if the recording to the IC card fails, the IC card 20 is re-inserted, so that the failed recording processing can be retried and the recording processing can be made as successful as possible.

[0031]

As described in detail above, according to the present invention, an IC card having a payment function is detachably held and mounted on a vehicle, and a toll collection process is performed by wireless communication with a roadside machine at a tollgate. When the information recording on the IC card is performed and the recording process on the IC card fails, the IC card is reinserted, and the reinserted IC card or the recording process fails. It is determined whether or not the IC card is the same as the IC card, and if the IC card is recognized as the same IC card, the failed recording process is retried.
When the card is re-inserted, the failed recording process can be retried to make the recording process as successful as possible, and high reliability can be obtained.
