JP6981104B2 - On-board unit - Google Patents

Description

It relates to an on-board unit used in an ETC (registered trademark) system.

In Patent Document 1, the expiration date of the IC card is notified at a predetermined notification timing set to be a timing before communication with the ETC (Electronic Toll Collection, automatic toll collection) roadside machine. Examples of the predetermined notification timing include when it is detected that the card has been removed, and when it is detected that an operation that leads to the engine stop has been performed, such as an ignition switch off operation. When it is detected that the predetermined notification timing is reached, the expiration date month is read from the IC card and the expiration date month is notified.

Japanese Unexamined Patent Publication No. 2006-285606

A new IC card should have arrived at home around the 20th of the expiration month. After the new IC card arrives, it is desirable to replace the card to be inserted into the in-vehicle device with a new IC card before the expiration date of the old IC card expires.

However, even if the expiration month is notified at the above predetermined timing, the driver does not have to do anything except when exchanging with a new IC card, so he gradually gets used to the notification of the expiration month. Will end up.

Therefore, even after the new IC card arrives at home, the driver may not recognize the need to replace it with a new IC card when the expiration date is notified. As a result, there was a risk of forgetting to replace the IC card with a new one before the expiration date.

The present disclosure has been made based on this circumstance, and an object thereof is to provide an in-vehicle device capable of suppressing forgetting to replace an IC card whose expiration date has passed with a new IC card. There is something in it.

It is equipped with a notification control unit (83) that outputs a deadline determination notification indicating the relationship between the deadline and the current date and time from the notification unit.
The notification control unit detects that the power is turned on and an IC card is inserted in the information reading unit, and notifies the expiration date when the card is detected when the information reading unit reads information about the expiration date. Is enabled, and even if the function to notify the expiration date is turned off, the deadline determination unit determines that the current date and time is after the notification reference date at the end. In this case, it is an in-vehicle device that outputs a deadline determination notification from the notification unit.

This on-board unit outputs a deadline determination notification from the notification unit. Since the expiration date judgment notification shows the relationship between the expiration date and the current date and time, the expiration date may or may not have passed sooner than the expiration date is notified. It is easy to recognize that you are there. Therefore, it is possible to prevent the IC card whose expiration date has passed from being forgotten to be replaced with a new IC card.

Further, the time for outputting the deadline determination notification from the notification unit is after the preset notification reference date in the latter half of the expiration date. After this notification reference date, a new IC card usually arrives. In addition, the timing for outputting the deadline determination notification from the notification unit is at least one of the time when the IC card is removed and the time when the power is turned off without removing the IC card. This timing is often the timing when the occupants of the vehicle get off the vehicle. If the vehicle is getting off at home, the person who hears the notification can actually exchange the IC card for a new one while remembering that the IC card must be exchanged. In this respect as well, it is possible to prevent the IC card whose expiration date has passed from being forgotten to be replaced with a new IC card.

It is a block diagram which shows the electric structure of the vehicle-mounted device 1. It is a flowchart which shows the process about the expiration date notification of the ETC card 2 executed by the control unit 80. It is a figure explaining the process to execute in S2, S4, S6 of FIG.

<Embodiment>
Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 shows the configuration of the on-board unit 1 of the embodiment. The vehicle-mounted device 1 is fixed in the vehicle. The fixed position is a storage unit prepared in advance for the on-board unit 1. Further, the mounting operator may fix the on-board unit 1 at an arbitrary position in the vehicle, such as the upper surface of the dashboard.

The on-board unit 1 reads information necessary for charge settlement from the ETC card 2. Then, the information necessary for toll collection, including the read information, is transmitted and received to and from the roadside machine provided at the ETC gate or the like.

The ETC card 2 is an IC card, and information necessary for charge settlement is recorded in the built-in IC. The information required for charge settlement is the card number, information on the expiration date, and so on. The information regarding the expiration date is specifically the expiration date of the ETC card 2.

[Electrical configuration of on-board unit 1]
As shown in FIG. 1, the on-board unit 1 includes a power supply unit 10, a road-to-vehicle communication unit 20, a speaker 30, a display unit 40, an operation unit 50, a GPS receiving unit 60, an information reading unit 70, and a control unit 80. ..

The power supply unit 10 is connected to the vehicle-mounted battery 3. The power supply unit 10 turns on the power of the vehicle-mounted device 1 when the key switch of the vehicle is turned on. In the power-on state, the power supply unit 10 supplies the electric power supplied from the vehicle-mounted battery 3 to various electrically operated elements included in the vehicle-mounted device 1. Then, when the key switch of the vehicle is turned off, the power supply unit 10 turns off the power of the vehicle-mounted device 1.

The road-to-vehicle communication unit 20 includes an antenna 21. The road-to-vehicle communication unit 20 performs road-to-vehicle communication with a road unit provided at an ETC gate or the like via the antenna 21, and transmits / receives information necessary for toll collection. In addition to that, the road-to-vehicle communication unit 20 can also communicate with roadside radio devices installed at various points on the road and receive traffic information.

The speaker 30 is a notification unit and outputs various voice messages and sounds other than voice. For example, the message may be that the ETC card 2 has been inserted, the card expiration month, and the like.

The display unit 40 is configured to include one or several (for example, two) LEDs, and the state of the vehicle-mounted device 1 is indicated by turning on, off, and blinking the LEDs.

The operation unit 50 includes several (for example, three) switches. For example, it has three switches: a volume switch, a usage history confirmation switch, and a card eject switch.

The GPS receiving unit 60 receives a navigation signal transmitted by a navigation satellite included in a GPS (Global Positioning System), which is one of the satellite navigation systems, and sequentially calculates the current position based on the received navigation signal. Then, the calculated current position is output to the control unit 80. Further, the current date and time included in the navigation signal is also output to the control unit 80.

The information reading unit 70 is a portion where the ETC card 2 is inserted, and detects whether or not the ETC card 2 is inserted. Then, when it is detected that the ETC card 2 is inserted, the information necessary for the charge settlement is read from the inserted ETC card 2. As described above, the information required for charge settlement includes the expiration month of the ETC card 2. The information reading unit 70 outputs the detection result of whether or not the ETC card 2 is inserted and the information read from the ETC card 2 to the control unit 80.

The control unit 80 is a computer equipped with a CPU, ROM, RAM, and the like. The CPU executes a program stored in a non-transitional and substantive recording medium such as a ROM while using the temporary storage function of the RAM, so that the control unit 80 is a communication control unit 81 and a deadline determination unit. 82, functions as a notification control unit 83. When these functions are executed, the method corresponding to the program is executed.

[Process executed by control unit 80]
The communication control unit 81 controls the road-to-vehicle communication unit 20 to communicate the road-to-vehicle communication unit 20 with the roadside machine or the roadside wireless communication device. When the road-to-vehicle communication unit 20 and the road unit installed at the ETC gate communicate with each other, the communication control unit 81 transmits and receives information necessary for toll collection.

The deadline determination unit 82 compares the expiration date month read from the ETC card 2 by the information reading unit 70 with the current date and time acquired from the GPS receiving unit 60. Then, it is determined whether or not the current date and time is after the preset notification reference date in the latter half of the expiration month. The notification reference date is set to the earliest day among the days when the new ETC card 2 is likely to arrive. In the present embodiment, it is assumed that the notification reference date is set to 20 days.

The notification control unit 83 has detected that the ETC card 2 has been inserted based on the information provided by the information reading unit 70, the expiration month of the ETC card 2, and the relationship between the expiration month and the current date and time. Various notifications such as a deadline determination notification indicating the above are output from the speaker 30.

FIG. 2 shows a process related to the expiration date notification of the ETC card 2 executed by the control unit 80. The process shown in FIG. 2 is periodically executed while the power of the vehicle-mounted device 1 is turned on.

In step (hereinafter, step is omitted) S1, it is determined whether or not the ETC card 2 is detected. Whether or not the ETC card 2 is detected is determined based on the signal from the information reading unit 70. The detection here means the case where the ETC card 2 can be detected normally. Therefore, it means that not only the detection that the ETC card 2 has been inserted but also the information could be read from the ETC card 2. Although it is detected that the ETC card 2 has been inserted, the processing of the abnormal state in which the information cannot be read from the ETC card 2 is not within the scope described in the present embodiment, and thus the description thereof will be omitted. If the judgment of S1 is NO, the judgment of S1 is repeated, and if YES, the process proceeds to S2.

In S2, the card detection processing is executed. FIG. 3 shows in a table format the card detection processing, the card removal processing executed in S4, and the key switch off processing executed in S6. The card detection process of S2 will be described with reference to FIG.

In the card detection processing, the portion where the notification condition is "card detection" in FIG. 3 is executed. As shown in FIG. 3, the card detection processing can be divided into three types: (A1) when GPS is not positioned, (A2) when GPS is positioned, and (A3) when GPS is positioned. Positioning GPS means a state in which the GPS receiving unit 60 can calculate the current position. In the state where the current position cannot be calculated, the control unit 80 cannot acquire the current date and time from the GPS receiving unit 60.

The GPS receiving unit 60 cannot calculate the current position immediately after the power of the vehicle-mounted device 1 is turned on. It may take a few seconds or more before the current position can be calculated. On the other hand, if the power of the vehicle-mounted device 1 is turned on while the ETC card 2 is still inserted in the information reading unit 70, it can be immediately detected that the ETC card 2 is inserted. Therefore, there may be a situation where the ETC card 2 is detected but the GPS is not positioned.

If the ETC card 2 is detected but the GPS is not positioned, the current date and time cannot be compared with the card expiration month. However, the expiration month of the ETC card 2 has been obtained. Therefore, when ETC card 2 was detected, but (A1) GPS was not positioned, after the sound of "pawn", "ETC card was inserted. Expiration date is ○○○○ year ○ The message "○ It's the month." Is output from the speaker 30.

After the process of (A1), GPS can usually be positioned after a while. At that time (A2), the processing when the GPS is positioned is executed. The process of (A2) is divided into three types of processes based on the comparison result between the current date and time and the expiration month. If the current date and time is before the 20th day of the expiration month, no processing is executed.

On the other hand, if the current date and time is between the 20th of the expiration month and the last day of the expiration month, or if the current date and time has passed the expiration month, a deadline judgment notification indicating the relationship between the expiration date and the current date and time will be sent. It is output from the speaker 30.

Specifically, if the current date and time is between the 20th of the expiration month and the last day of the expiration month, the end of this month will be "The expiration date of the ETC card is the end of this month" after the sound of "pawn". The message is output from the speaker 30. This message is a deadline determination notice, and in particular, corresponds to a notice at the end of this month. If the current date and time has passed the expiration month, the speaker 30 outputs an expiration date message "The ETC card has expired." After a beeping sound. The expiration date message is an expiration date determination notification, and particularly corresponds to an expiration date notification.

Further, after outputting the expiration date message from the speaker 30, the beeping sound is continued until the ETC card 2 is removed or the on-board unit 1 is turned off by turning off the key switch of the vehicle. Is output from the speaker 30. This "beep" sound is output following the expired message, and functions as a sound indicating that the expiration date has passed.

When the ETC card 2 is detected, (A3) the processing when the GPS is positioned is also divided into three types of processing based on the comparison result between the current date and time and the expiration date. If the current date and time is before the 20th day of the expiration month, the same sound and message as in (A1) are output from the speaker 30. When the process of (A3) is executed, since the process of (A1) is not executed, the same sound and message as in (A1) are output from the speaker 30 in order to notify the occupant that the ETC card 2 has been detected. Let me do it.

If the current date and time is from the 20th day of the expiration month to the last day of the expiration month, and if the current date and time has passed the expiration month, the same sound and message as in (A2) are output from the speaker 30. In this case, the message notified in the case of (A1) will be omitted.

When S2 is executed, S3 and subsequent steps are executed. After S3, it is a process when the on-board unit 1 ends the operation in the card inserted state. The operation of the card inserted state is divided into two cases, one is when the ETC card 2 is removed and the other is when the power of the on-board unit 1 is turned off with the ETC card 2 inserted.

Therefore, in S3, it is determined whether or not the ETC card 2 has been removed. The ETC card 2 inserted in the information reading unit 70 can be removed by operating the eject switch of the operating unit 50. If the judgment of S3 is YES, the process proceeds to S4.

In S4, the card removal processing is executed. This card extraction process will also be described with reference to FIG. In the card withdrawal process, the part where the notification condition is "card withdrawal" is executed in FIG. As shown in FIG. 3, the card removal processing can be divided into two types: (B1) when GPS is not positioned and (B2) when GPS is positioned. In the case of (B1), no sound or message is output from the speaker 30.

The process of (B2) is divided into three types of processes based on the latest determination result of determining the relationship between the current date and time and the expiration month. To determine the relationship between the current date and time and the expiration date, specifically, whether the current date and time is before the notification reference date, or whether the expiration month is between the 20th and the end of the month, is valid. It determines whether the deadline has passed.

If it is determined that the current date and time has passed the expiration month at the time of card detection, the current date and time will be acquired again, no re-judgment will be performed, and the judgment result at the time of card detection will be used as the latest judgment result. .. This is because the current date and time has passed the expiration month without making a re-judgment.

On the other hand, if it is determined that the current date and time is before the notification reference date or the expiration date is between the 20th and the end of the month at the time of card detection, the current date and time will be acquired again. And make a re-judgment. This is because the judgment result may be different from that at the time of card detection depending on the passage of time from the time of card detection. By making this re-judgment, it is possible to prevent notification of incorrect information.

If the current date and time is before the 20th day of the expiration month, no processing is executed. If the current date and time is between the 20th day of the expiration month and the last day of the expiration month, the same sounds and messages as in (A2) and (A3) are output from the speaker 30. If the current date and time has passed the expiration month, the speaker 30 outputs the same expiration message "ETC card has expired" that was output when the card was detected.

If the judgment of S3 is NO, the process proceeds to S5. In S5, it is determined whether or not the key switch is turned off. If this judgment is NO, the process returns to S3. On the other hand, if the judgment of S5 is YES, the process proceeds to S6.

In S6, the key switch off processing is executed. If the judgment of S3 is YES, that is, if the key switch is turned off while the ETC card 2 is removed, nothing is notified.

The process when the key switch is turned off will also be described with reference to FIG. In the key switch off processing, the portion where the notification condition is "vehicle key switch off" is executed in FIG.

As shown in FIG. 3, the key switch off processing can be divided into two types: (C1) when GPS is not positioned and (C2) when GPS is positioned. In addition, (C1) and (C2) are further divided into card removal forgetting warning on, card removal forgetting warning off, and card not inserted. However, in the case of (C1), the notification is given only when the card removal forgetting warning is on, and nothing is notified when the card removal forgetting warning is off and the card is not inserted. In (C1), when the card removal forgetting warning is on, the speaker 30 outputs the message "the card remains" after the beeping sound.

The card removal warning is a process of notifying that the ETC card 2 is inserted in the vehicle-mounted device 1 when the vehicle key switch is turned off. The card removal warning can be switched on and off by the user operating the operation unit 50.

In the case of (C2), the processing when the card removal forgetting warning is on and the card removal forgetting warning is off is based on the latest judgment result of judging the relationship between the current date and time and the expiration month. Divide into different types of processing. If it is determined that the current date and time has passed the expiration month at the time of card detection, the relationship between the current date and time and the expiration month will not be re-determined. On the other hand, if it is determined that the current date and time is before the notification reference date or the expiration date is between the 20th and the end of the month at the time of card detection, the current date and time will be acquired again. And make a re-judgment. This point is the same as the processing in the case of (B2).

In the case of (C2), three types of processing when the card removal forgetting warning is on will be described. If the current date and time is before the 20th day of the expiration month, the same sound and message as in the case of (C1) are output from the speaker 30. If the current date and time is between the 20th day of the expiration month and the last day of the expiration month, the same sounds and messages as in the cases of (A2), (A3), and (B2) are output from the speaker 30. If the current date and time has passed the expiration month, the same sound and message as in (B2) are output from the speaker 30. Therefore, in the case of (C2), if the current date and time is between the 20th of the expiration month and the last day of the expiration month, and if the current date and time has passed the expiration month, the card is forgotten to be removed. Even if the warning is on, it does not directly notify that the ETC card 2 remains. Instead, it will notify you that it has expired at the end of this month or has expired.

If a message at the end of this month or an expired message is notified, it is considered that the occupants can often recognize that the ETC card 2 remains without directly notifying that the ETC card 2 remains. .. Therefore, it does not directly notify that the card remains. As a result, in addition to the message at the end of this month or the expiration date, it is notified that the card remains, which can be suppressed from causing trouble to the occupant, and the message at the end of this month or the expiration date can be sent to the occupant. It can be more recognized.

Next, in the case of (C2), the process when the card removal forgetting warning is off will be described. If the current date and time is before the 20th of the expiration month, nothing will be notified. The processing when the current date and time is from the 20th of the expiration month to the last day of the expiration month and when the current date and time has passed the expiration month are the same as when the card removal forgetting warning is on. .. Therefore, in the case of (C2), even if the card removal forgetting warning is off, the message at the end of this month or the expired message will be notified.

When it is notified that the ETC card 2 remains every time the key switch is turned off, many users find it annoying, so many users turn off the card removal warning. However, in the present embodiment, even if the card removal forgetting warning is turned off, the message at the end of this month or the expired message is notified. As a result, it is possible to prevent the ETC card 2 from being forgotten to be replaced by turning off the card removal forgetting warning. In addition, if you exchange for a new ETC card 2, you will not be notified of the end-of-month message and the expired message. Therefore, there is little possibility that the message will be notified many times and cause annoyance to the occupants.

In the case of (C2), if the card is not inserted, no notification is given. In the processes described above, the deadline determination unit 82 executes each of the processes S1, S3, and S5. Further, when the processes of S2, S4, and S6 are executed, the expiration date determination unit 82 also executes a comparison between the current date and time and the expiration date month. In the processes of S2, S4, and S6, the notification control unit 83 executes the remaining processes.

[Summary of embodiments]
The vehicle-mounted device 1 of the present embodiment outputs a deadline determination notification from the speaker 30. The expiration date judgment notification is specifically a message at the end of this month or an expiration date message, and these messages have an expiration date that will expire sooner than the expiration date notification, or the expiration date will expire. It is easy to recognize that it has passed.

In addition, the time to notify the deadline determination notification is after the 20th day of the expiration month. If it is after the 20th of the expiration month, a new ETC card 2 usually arrives. In addition, the timing for outputting the deadline determination notification from the speaker 30 is when the ETC card 2 is removed and when the vehicle-mounted device 1 is turned off without removing the ETC card 2. These timings are often the timings when the occupants of the vehicle get off the vehicle. Then, if the vehicle is disembarked at home, the person who hears the notification can actually exchange the ETC card 2 for a new ETC card 2 while remembering that the ETC card 2 must be exchanged. From these facts, the on-board unit 1 of the present embodiment can prevent the ETC card 2 whose expiration date has passed from being forgotten to be replaced with a new ETC card 2.

<Modification 1>
In the above-described embodiment, after the expiration date message is output, a beeping sound is continuously output until the ETC card 2 is removed or the power is turned off. However, there is a possibility that the meaning of the sound may be forgotten just by continuously outputting the "beep" sound. Therefore, this sound may be interrupted periodically to output an expired message periodically.

<Modification 2>
In the above-described embodiment, when the expiration date of the ETC card 2 has expired, an expiration date message is output when the card is detected, and then a beeping sound is continuously output. Then, when the card was removed and the key switch was turned off, the expiration date message was output again. However, you may omit the expired message again. In this case, the beeping sound that continues until the card is removed and the key switch is turned off corresponds to the expiration date notification. In addition, this modification 2 may be combined with the modification 1.

<Modification 3>
The function of outputting the message at the end of this month, which is the notification at the end of this month, may be turned on / off by the user operating the operation unit 50. However, even if the function to output the notification at the end of this month is turned off, only the function to output the notification at the end of this month is turned off in the card detection processing, and the notification at the end of this month is sent in the card removal processing and the key switch off processing. It is preferable to keep the output function on.

Even if the notification at the end of this month is output when the card is detected, it is not often possible to replace it with a new ETC card 2, but it is considered that it is often possible to replace it with a new ETC card 2 when the card is removed or the power is turned off. .. Therefore, it is preferable to turn off only the function of outputting the notification at the end of this month in the card detection processing.

<Modification example 4>
In the card detection processing, the function of outputting a message notifying the expiration date may be turned on / off by the user operating the operation unit 50.

<Modification 5>
In the above-described embodiment, in the card detection processing executed in S2, when (A1) GPS is not positioned, the same sound and message are emitted without comparing the expiration month of the ETC card 2 with the current date and time. It was outputting. This is because the date and time cannot be obtained at present.

However, the following processing may be performed by remembering the card number of the ETC card 2 detected at the time of the previous startup and the fact that the expiration date notification was output at the time of the previous power off.

That is, if the ETC card 2 detected this time is the same as the ETC card 2 detected at the time of the previous startup, and the expiration date message was output last time, in the processing at the time of the card detection this time (A1). In processing, an expired message may be output.

<Modification 6>
In the above-described embodiment, the GPS receiving unit 60 acquires the current date and time from the navigation signal, and the control unit 80 acquires the current date and time from the GPS receiving unit 60. Instead, if the on-board unit 1 is mounted on a vehicle and connected to an in-vehicle device capable of providing the current date and time, for example, a navigation device, the on-board unit 1 may acquire the current date and time from the in-vehicle device. good.

<Modification 7>
Further, when the on-board unit 1 is connected to a display device mounted on the vehicle, for example, a navigation device, the on-board unit 1 uses the display device as a notification unit and causes the display device to output a deadline determination notification. You may. Therefore, the deadline determination notification may be displayed. At this time, the deadline determination notification by sound may also be output.

<Modification 8>
Instead of the speaker 30 provided in the vehicle-mounted device 1, the speaker provided in the vehicle may be used to output the deadline determination notification.

<Modification 9>
In the above-described embodiment, the notification reference date is set to 20 days, but the notification reference date is not limited to 20 days. The notification reference date can be arbitrarily set to a date such as 19th or 21st, which is determined by the user to be a date on which a new ETC card 2 is likely to arrive.

<Modification 10>
In the above-described embodiment, if it is determined that the current date and time has passed the expiration month at the time of card detection, the determination result at the time of card detection is the latest determination as it is in the card extraction process and the key switch off process. As a result. However, regardless of whether or not it is determined that the current date and time has passed the expiration month at the time of card detection, the current date and time is acquired again in the card removal process and the key switch off process, and the current date and time is used. You may re-determine the relationship with the expiration month.
