The storage unit 62 stores the vehicle identification information and the recovery information received by the network communication unit 61. Further, the storage unit 62 stores the program executed by the control unit 63.

The control unit 63 is composed of a processor and performs various processes by executing a program stored in the storage unit 62. In this embodiment, recovery information is managed. That is, when the network communication unit 61 receives the vehicle identification information and the recovery information transmitted from the roadside device 3 of the entrance tollhouse, the recovery information is stored in the storage unit 62 in association with the vehicle identification information.

Further, when the network communication unit 61 receives the recovery request transmitted from the roadside device 4 in the recovery dedicated area, the control unit 63 receives the vehicle identification information included in the recovery request from the recovery information stored in the storage unit 62. The recovery information corresponding to is selected, and the recovery information is transmitted from the network communication unit 61 to the roadside device 4.

Next, the operation procedure of this system when the vehicle passes through the entrance tollhouse will be described. FIG. 6 is a sequence diagram showing an operating procedure of the system when a vehicle passes through an entrance tollhouse. FIG. 6 describes a case where the ETC card 1 is not installed.

First, in the in-vehicle device 2, the control unit 23 acquires vehicle information from the storage unit 22 and generates uplink information including the vehicle information. Then, the road-to-vehicle communication unit 21 transmits the uplink information to the roadside device 3.

In the roadside device 3, when the road-to-vehicle communication unit 31 receives the uplink information transmitted from the vehicle-mounted device 2, the control unit 34 acquires the vehicle identification information from the vehicle information included in the uplink information. In addition, recovery information including entrance information (identification information of entrance tollhouse, passage date / time information, etc.) and measurement information (license plate information, etc.) is generated. Then, the network communication unit 32 transmits the vehicle identification information and the recovery information to the management device 6.

In the management device 6, when the network communication unit 61 receives the vehicle identification information and the recovery information transmitted from the roadside device 3, the control unit 63 stores the recovery information in the storage unit 62 in association with the vehicle identification information.

Further, in the roadside device 3, the control unit 34 generates downlink information including notification information regarding notification that recovery is required. Then, the road-to-vehicle communication unit 31 transmits the downlink information to the in-vehicle device 2.

In the in-vehicle device 2, when the roadside device 21 receives the downlink information transmitted from the roadside device 3, the vehicle-mounted device 2 notifies that recovery is necessary based on the notification information included in the downlink information, specifically. ETC card 1 is attached to the device, and a notification voice prompting the user to perform recovery in the recovery area is output.

In addition to outputting the notification voice at the timing of passing through the entrance tollhouse, it is preferable to repeatedly output the notification voice until recovery is performed.

In addition to the notification that recovery is necessary, it is advisable to give a notification indicating the recovery point, specifically, a notification indicating which service area or parking area has the recovery-dedicated area.

When the in-vehicle device 2 is equipped with the ETC card 1, the in-vehicle device 2 acquires the card information from the ETC card 1 and transmits the uplink information including the card information and the vehicle information to the roadside device 3. Send to. Therefore, the roadside device 3 can determine whether or not the ETC card 1 is not installed, depending on whether or not the uplink information includes the card information.

Further, when the ETC card 1 is attached to the in-vehicle device 2, the roadside device 3 performs a normal process. That is, downlink information including entrance information (identification information of the entrance tollhouse, passage date / time information, etc.) and measurement information (license plate information, etc.) is generated, and the downlink information is transmitted to the in-vehicle device 2. In the in-vehicle device 2, the entrance information and the measurement information acquired from the roadside device 3 are written in the ETC card 1.

By the way, if the uplink information is not properly transmitted / received, the vehicle information cannot be obtained from the uplink information, and therefore the recovery cannot be performed. Therefore, as information for notifying the user that recovery is necessary, downlink information including information on whether or not recovery is possible is generated and transmitted to the in-vehicle device 2. At this time, if the vehicle information can be acquired, recovery becomes possible, and if the vehicle information cannot be acquired, recovery becomes impossible.

Then, in the in-vehicle device 2, if recovery is possible based on the information regarding the possibility of recovery included in the downlink information, a notification that recovery is necessary is given. On the other hand, if recovery is not possible, the notification that recovery is necessary is not given, or the notification that recovery is not possible is given.

Next, the operation procedure of this system when the vehicle enters the recovery-dedicated area will be described. FIG. 7 is a sequence diagram showing an operation procedure of the system when the vehicle enters the recovery-dedicated area.

First, in the in-vehicle device 2, the control unit 23 acquires vehicle information from the storage unit 22 and generates uplink information including the vehicle information. Then, the road-to-vehicle communication unit 21 transmits the uplink information to the roadside device 4.

In the roadside device 4, when the road-to-vehicle communication unit 41 receives the uplink information transmitted from the in-vehicle device 2, the control unit 44 acquires the vehicle identification information from the vehicle information included in the uplink information and performs network communication. The unit 42 transmits a recovery request including the vehicle identification information to the management device 6.

In the management device 6, when the network communication unit 61 receives the recovery request transmitted from the roadside device 4, the management device 6 receives the recovery information of each vehicle stored in the storage unit 62 based on the vehicle identification information included in the recovery request. Obtain the recovery information of the corresponding vehicle from the inside. Then, the network communication unit 61 transmits the recovery information to the roadside device 4.

In the roadside device 4, when the network communication unit 42 receives the recovery information transmitted from the management device 6, the control unit 44 generates downlink information including the recovery information. Then, the road-to-vehicle communication unit 41 transmits the downlink information to the in-vehicle device 2.

In the in-vehicle device 2, when the road-to-vehicle communication unit 21 receives the downlink information transmitted from the roadside device 4, the control unit 23 acquires the recovery information included in the downlink information and transfers the recovery information to the ETC card 1. Performs the process of writing to.

It is also possible that a vehicle that is not a recovery target vehicle, that is, a vehicle that has passed the entrance tollhouse with the ETC card 1 attached, accidentally enters the recovery-dedicated area. In this case, the management device 6 determines that the vehicle is not the recovery target vehicle based on the vehicle identification information of the recovery target vehicle that is being managed, transmits notification information that the vehicle is not the target, to the roadside device 4, and further targets the target. The notification information indicating that the vehicle is outside is transmitted from the roadside device 4 to the vehicle-mounted device 2, and the vehicle-mounted device 2 outputs a notification indicating that the vehicle is out of scope.

By the way, in the present embodiment, the entrance tollhouse is a free flow in which the opening / closing bar is not installed, but when the entrance tollhouse is provided with the opening / closing bar and the ETC card 1 is not installed, The entrance toll ticket may be issued without opening the opening / closing bar. In this case, a reading device for reading the entrance toll ticket may be connected to the roadside device 4 in the recovery-only area to read the information stored in the entrance toll ticket, and recovery may be performed based on the information.

At this time, if the recovery information (entrance information and measurement information) is stored in the entrance pass ticket, the recovery information does not need to be managed by the management device 6, so that the management device 6 becomes unnecessary. On the other hand, if only the entrance information is stored in the entrance pass ticket, it is necessary to provide the measurement information to the roadside device 4, so that the management device 6 is necessary.

In addition, since the entrance toll ticket may be used illegally, the management device 6 manages the entrance toll ticket identification information as the entrance toll ticket issuance information in association with the vehicle identification information of the vehicle that issued the entrance toll ticket. It is good to do it. Alternatively, the management device 6 may manage the identification information of the entrance toll ticket in association with the information on whether or not the recovery process has already been performed. As a result, it is possible to prevent the unauthorized use of the entrance ticket, such as reusing the entrance ticket, that is, prohibiting the reuse of the entrance ticket used in the recovery in the past.

Next, a modified example of this embodiment will be described. FIG. 8 is an explanatory diagram showing an outline of an ETC recovery system according to a modified example of the present embodiment.

In the present embodiment, as shown in FIG. 2, as a recovery point, a recovery-dedicated area is provided in a resting parking facility (service area, parking area, etc.) provided in the toll road, and the recovery is provided here. In this modified example, the recovery point is set on the main line of the toll road, and the roadside device 71 is located near the main line. Is installed, and a roadside antenna 72 is installed on the main line. As a result, recovery can be performed while the vehicle is traveling on the main line.

This roadside device 71 is a so-called ITS spot, and in ITS (Intelligent Transport Systems), road information, that is, information on traffic congestion and road conditions such as falling objects and snow on the road, is provided to the vehicle. The in-vehicle device 2 receives the downlink information transmitted from the roadside device 71, which is provided to the driver, and the road information is displayed on the car navigation device mounted on the vehicle.

When recovery is performed using this roadside device 71, uplink information including vehicle information is transmitted from the in-vehicle device 2 to the roadside device 71, and the recovery information is also transmitted, as in the case of the roadside device 4 installed in the recovery dedicated area. The including downlink information is transmitted from the roadside device 71 to the vehicle-mounted device 2.

At this time, the management device 6 transmits vehicle identification information and recovery information of all recovery target vehicles to the roadside device 71, and the roadside device 71 transmits vehicle identification information and recovery of all recovery target vehicles received from the management device 6. If the downlink information including the information is transmitted to the in-vehicle device 2, the in-vehicle device 2 selects the recovery information of the own vehicle based on the vehicle identification information included in the downlink information and performs the recovery. good.

In this case, since the driver cannot know that the recovery has been performed, it is preferable to notify the driver that the recovery has been completed by the in-vehicle device 2 or the car navigation device.

Further, in this modification, recovery is performed by the roadside device 71 (ITS spot) installed on the main line of the toll road, but as shown in FIG. 2, the recovery itself is installed in the recovery-dedicated area. In the roadside device 71 installed on the main line, the notification information indicating that recovery is necessary may be transmitted to the in-vehicle device 2.

At this time, the management device 6 transmits vehicle identification information and notification information of all recovery target vehicles to the roadside device 71, and the roadside device 71 transmits vehicle identification information and notification of all recovery target vehicles received from the management device 6. The downlink information including the information is transmitted to the in-vehicle device 2, and when the in-vehicle device 2 determines that the own vehicle is a recovery target vehicle based on the vehicle identification information included in the downlink information, the in-vehicle device 2 outputs notification information. do it.

By the way, the roadside device for recovery may be installed immediately in front of the exit tollhouse. In this case, it is not desirable to stop the vehicle at the exit tollhouse, so recovery information should be sent and received while the vehicle is running, as in the case of installing the roadside device (ITS spot) on the main line. It is good to do.

In addition, recovery may be performed at an entrance tollhouse equipped with only ETC dedicated lanes, a so-called roadside device installed at a smart interchange. In this case, an approach road to the entrance tollhouse will be provided to join the vehicles entering from the general road. Therefore, it is preferable to identify the vehicle entering from the general road and the vehicle to be recovered based on the vehicle identification information managed by the management device 6.

Next, another modification of the present embodiment will be described. FIG. 9 is an overall configuration diagram of an ETC recovery system according to another modification of the present embodiment.

In the present embodiment, the in-vehicle device 2 is used to notify that recovery is necessary, but in this modified example, the user owns a smartphone, tablet terminal, or the like to notify that recovery is necessary. It is done by the mobile terminal device 9.

The mobile terminal device 9 can communicate with the management device 6 via a wireless communication network such as cellular communication. Based on the information transmitted from the roadside device 3 of the entrance tollhouse, the management device 6 has a mobile phone possessed by the user of the vehicle if there is a vehicle that has passed the entrance tollhouse without the ETC card 1 installed. The notification information that recovery is necessary is transmitted to the terminal device 9, and the mobile terminal device 9 outputs a notification that recovery is necessary based on the received notification information.

In this case, if an application dedicated to the ETC service is installed in the mobile terminal device 9, the application receives the notification information transmitted from the management device 6 and outputs a notification that recovery is required. good.

At this time, the management device 6 may be accessed from the application running on the mobile terminal device 9, inquired about the presence or absence of the notification, and the management device 6 transmits the notification information in response to the notification, which is a so-called pull-type notification. In this case, it is not necessary to register the address of the mobile terminal device 9 in the management device 6 in advance. On the other hand, it may be a so-called push-type notification in which the management device 6 actively transmits the notification information to the mobile terminal device 9, and in this case, it is necessary to register the address of the mobile terminal device 9 in the management device 6 in advance. be.

(Second Embodiment)
Next, the second embodiment will be described. FIG. 10 is an explanatory diagram showing a state of a recovery point according to the second embodiment. It should be noted that the points not particularly mentioned here are the same as those in the above-described embodiment.

In the present embodiment, the recovery point is set on the main line of the toll road, the roadside device 71 (ITS spot) is installed in the vicinity of the main line, and the roadside antenna is on the main line, as in the modified example shown in FIG. 72 are installed.

In such a roadside device 71, since the vehicle is traveling at high speed, the influence of the Doppler shift becomes large in the road-to-vehicle communication performed with the in-vehicle device 2, and the wireless performance is significantly deteriorated due to the Doppler shift. Become.

On the other hand, the road-to-vehicle communication between the roadside device 71 and the vehicle-mounted device 2 is narrow-area communication, and since the communication area of the roadside antenna 72 is narrow, the time during which signals can be transmitted and received between the roadside device 71 and the vehicle-mounted device 2 Is short. For this reason, when sufficient time cannot be secured for the operation of establishing communication, the process of reducing the influence of Doppler shift is not in time in the process of establishing communication, and recovery information cannot be transmitted and received appropriately. There is.

Therefore, in the present embodiment, a vehicle speed detection device 73 that detects the vehicle speed is installed on the front side of the communication area of the roadside antenna 72, and the Doppler is based on the vehicle speed detected by the vehicle speed detection device 73. Performs frequency shift processing to eliminate the frequency shift due to shift.

Here, if the vehicle speed detection device 73 is installed immediately before the communication area of the roadside antenna 72, the vehicle speed when the vehicle reaches the communication area of the roadside antenna 72 and the detected vehicle speed do not differ significantly. Therefore, the frequency shift process can be performed with high accuracy.

Further, since the Doppler shift is affected by the relative speed of the vehicle with respect to the roadside antenna 72, the detected vehicle speed and the positional relationship between the vehicle-mounted device 2 of the vehicle on the road and the roadside antenna 72 are taken into consideration. Therefore, the Doppler shift amount, that is, the frequency shift amount (deviation amount) due to the Doppler effect is calculated, and the frequency shift process is performed based on the Doppler shift amount.

Further, the frequency shift processing is performed on both the transmission signal and the reception signal. That is, in the frequency shift processing for the transmission signal, the frequency of the transmission signal is adjusted so that the in-vehicle device 2 can receive the transmission signal at a regular frequency. Further, in the frequency shift process for the received signal, the received signal received by the roadside antenna 72 is converted into a regular frequency.

Although the vehicle speed detection device 73 is provided in the present embodiment, the vehicle speed and the Doppler shift amount may be detected by a detection device installed on the road and detecting a moving object on the road, for example, an infrastructure radar. good.

Next, the schematic configuration of the roadside device 71 will be described. FIG. 11 is a block diagram showing a schematic configuration of the roadside device 71.

The roadside device 71 includes a road-to-vehicle communication unit 81, a network communication unit 82, a storage unit 83, and a control unit 84, similarly to the roadside device 4 for recovery (see FIG. 4) in the first embodiment. ing.

The control unit 84 includes a Doppler shift amount calculation unit 86. The Doppler shift amount calculation unit 86 calculates the Doppler shift amount based on the vehicle speed detected by the vehicle speed detection device 73. At this time, the Doppler shift amount at the time of reception is calculated based on the beam direction when the radio signal transmitted from the vehicle-mounted device 2 of the vehicle is received by the roadside antenna 72 and the traveling direction of the vehicle. Further, the Doppler shift amount at the time of transmission is calculated based on the beam direction transmitted by the roadside antenna 72 toward the vehicle-mounted device 2 of the vehicle and the traveling direction of the vehicle.

Here, a mathematical formula expressing the correlation between the vehicle speed and the Doppler shift amount in consideration of the beam direction and the traveling direction of the vehicle is stored in advance in the storage unit 83, and the Doppler shift amount is calculated from the vehicle speed using this mathematical formula. It may be calculated. Further, a frequency shift table showing the correlation between the vehicle speed and the Doppler shift amount may be stored in advance in the storage unit 83, and the Doppler shift amount may be obtained from the vehicle speed by referring to this frequency shift table. ..

The road-to-vehicle communication unit 81 includes a modulation unit 91, a demodulation unit 92, a frequency shift unit 93, a D / A conversion unit 94, an A / D conversion unit 95, an RF unit 96, and a roadside antenna 72. I have.

When the downlink information is transmitted, the modulation unit 91 modulates the transmission data generated by the control unit 84, and the frequency shift unit 93 performs frequency shift processing on the baseband signal output from the modulation unit 91 to shift the frequency. The baseband signal output from the unit 93 is converted into an analog signal by the D / A conversion unit 94, the analog signal output from the D / A conversion unit 94 is input to the RF unit 96, and the radio signal is transmitted from the roadside antenna 72. Will be sent.

On the other hand, when the uplink information is received, the radio signal transmitted from the in-vehicle device 2 is received by the roadside antenna 72, and the analog signal output from the RF unit 96 is converted into a baseband signal by the A / D conversion unit 95. The frequency shift process for the baseband signal output from the A / D conversion unit 95 is performed by the frequency shift unit 93, the demodulation of the baseband signal output from the frequency shift unit 93 is performed by the demodulation unit 92, and the demodulation unit 92. The received data output from is input to the control unit 84.

Here, the frequency shift unit 93 responds to the Doppler shift amount for each of the baseband signal at the time of transmission and the baseband signal at the time of reception based on the Doppler shift amount acquired by the Doppler shift amount calculation unit 86. Frequency shift processing is performed.

At this time, the presence / absence of the frequency shift processing may be switched according to the vehicle speed and the Doppler shift amount. For example, if the vehicle speed is less than a predetermined threshold value, the frequency shift process is not performed, and if the Doppler shift amount is less than the predetermined threshold value, the frequency shift process is not performed. good.

Further, the frequency shift process may be performed by controlling the local oscillator.

In the present embodiment, the vehicle speed detection device 73 is provided, and the frequency shift process for eliminating the frequency shift due to the Doppler shift is performed based on the vehicle speed detected by the vehicle speed detection device 73. A Doppler frequency detection device that detects the Doppler frequency (the difference between the frequency changed by the Doppler shift and the original frequency) may be provided, and the frequency shift process may be performed using the detection result.

Further, in the present embodiment, the frequency shift process is performed in the roadside device 71 (ITS spot) for recovery installed on the main line of the toll road, but this frequency shift process is not limited to the communication for recovery. ..

For example, the frequency shift process may be applied to a roadside device at a free-flow entrance tollhouse. At the free-flow entrance tollhouse, since the vehicle passes through without decelerating, the vehicle passes through the communication area of the roadside antenna at a relatively high speed, so that a great effect can be obtained in the frequency shift process.

Further, the frequency shift process is not limited to such ETC, that is, communication related to toll collection at a tollhouse on a toll road. For example, even on a general road, a roadside device is installed for the purpose of providing road information, and the frequency shift process may be performed by such a roadside device.

Next, a modified example of this embodiment will be described. FIG. 12 is an explanatory diagram showing the acquisition status of vehicle identification information in the roadside devices 3 and 4 according to the present embodiment and its modified example.

In the present embodiment, as shown in FIG. 12A, in the roadside device 3 of the entrance tollgate and the roadside device 4 of the recovery dedicated area, the uplink information transmitted from the in-vehicle device 2 in order to identify the vehicle is used. The vehicle identification information is acquired from the included vehicle information and the vehicle identification information is transmitted to the management device 6, but as shown in FIGS. 12C and 12D, the roadside device 3 of the entrance tollgate The vehicle number acquired by image recognition of the captured image by the camera 7 (first imaging device, see FIG. 4) may be transmitted to the management device 6 as vehicle identification information. Further, as shown in FIGS. 12B and 12D, a camera 101 (second image pickup device) is installed in the recovery dedicated area, the camera 101 is connected to the roadside device 4, and the roadside device 4 is used. Similar to the roadside device 3 of the entrance tollhouse, the vehicle number acquired by image recognition of the captured image by the camera 101 may be transmitted to the management device 6 as vehicle identification information.

Here, in the example shown in FIG. 12B, the roadside device 3 at the entrance tollhouse acquires the vehicle identification information from the uplink information, and the roadside device 4 in the recovery-only area identifies the vehicle from the image taken by the camera 101. I try to get information. Further, in the example shown in FIG. 12C, the roadside device 3 at the entrance tollhouse acquires the vehicle identification information from the image taken by the camera 7, and the roadside device 4 in the recovery-dedicated area obtains the vehicle identification information from the uplink information. I am trying to get. Further, in the example shown in FIG. 12D, both the roadside device 3 at the entrance tollhouse and the roadside device 4 in the recovery-dedicated area acquire vehicle identification information from the captured images of the cameras 7 and 101. ..

In the present embodiment, in the management device 6, in order to identify the vehicle based on the vehicle identification information acquired from the roadside device 3 of the entrance tollhouse and the roadside device 4 of the recovery dedicated area, the roadside devices 3 and 4, respectively. The vehicle identification information to be acquired must be the same information. Therefore, in the example shown in FIG. 12 (A), the vehicle identification information acquired from the vehicle information of the uplink information may be the identification information (vehicle identification number) of the vehicle-mounted device 2, but FIGS. 12 (B) and 12 (C) In the example shown in (1), the vehicle identification information acquired from the vehicle information of the uplink information has the same vehicle number as the vehicle identification information acquired from each of the captured images of the cameras 7 and 101.
