BACKGROUND OF THE INVENTION
The present invention relates to a toll collection device and method, a warning device and method, and a program in which a plurality of displays are displayed when a predetermined request to a driver of a vehicle is displayed.
[0002]
[Prior art]
In recent years, non-stop automatic toll collection (ETC (Electronic Toll Collection)) systems have begun to spread.
[0003]
The ETC system, for example, collects tolls by wireless communication with in-vehicle devices at a toll gate such as an expressway without stopping the vehicle.
[0004]
By the way, because the ETC system allows the toll booth to pass without stopping the vehicle, for example, when the prepaid card installed in the in-vehicle device has no balance and cannot collect the fee Measures are required.
[0005]
As such a countermeasure, for example, there is a system that displays a warning message on a warning display board or the like that is provided at a predetermined distance from a toll gate for a vehicle for which a toll was not collected.
[0006]
This makes it possible for the driver of a vehicle that has passed without paying a toll to be aware that the toll has not been paid, and then, for example, guides the vehicle to a manned toll gate Can do. Further, it has been proposed not only to display a message on a warning display board but also to display various information for the driver to notice.
[0007]
For example, JP-A-6-28596 and JP-A-10-261192 disclose a vehicle that exceeds the speed based on a photographed image together with a message that notifies the vehicle that the speed is exceeded. It is disclosed that the license plate number acquired in this way is displayed on a warning display board, and it is also proposed to apply this to a warning system as described above.
[0008]
As a result, a message notifying that effect and a license plate number are displayed for the vehicle that has not been able to collect the toll, thereby further alerting the driver.
[0009]
[Problems to be solved by the invention]
However, in the warning system as described above, although the warning displayed itself is to alert the driver more by displaying the license plate number, the warning display board is generally Since there is only one place, there is a problem that the driver misses the warning.
[0010]
The present invention has been made in view of such a situation, and is intended to make a driver confirm warnings and the like more reliably.
[0011]
[Means for Solving the Problems]
In order to solve the above-described problems, the toll collection device of the present invention communicates with a terminal mounted on a vehicle via radio, collects a toll for a predetermined road, and images the appearance of the vehicle. To pay the toll if it is determined that the toll is not collected by the first judging means and the first judging means for judging whether or not the toll is collected by the collecting means If the toll is not collected by the first display means for displaying the payment request for requesting the vehicle and the first judging means, is the toll collected again by the collecting means? A second determination means for determining whether or not a toll is not collected by the second determination means, a payment request including an image of the appearance of the vehicle imaged by the imaging means is issued to the vehicle Display And a second display means.
[0012]
For example, the fee collection device is installed near an entrance or exit of a toll road such as an expressway, and collects a fee from a vehicle passing there. The vehicle includes not only four-wheeled vehicles such as passenger cars, buses, and trucks but also two-wheeled vehicles such as motorcycles.

[0097]
Specifically, the warning control device 21 determines that there is a vehicle that does not pay the toll in the collection area 1 based on the output from the antenna 9 (there is a driver who does not perform a toll payment operation). Then, the license plate number is extracted from the image photographed by the license plate photographing camera 5, and a message requesting payment of the toll is displayed on the warning display unit 7 together with the number.
[0098]
The warning control device 21 determines whether or not the driver who has not paid the toll in the collection area 1 has performed a toll payment operation in the collection area 2 in response to the payment request being displayed on the warning display unit 7. Is determined based on the output from the antenna 10. Then, the warning control device 21 photographed the vehicle exterior photographing camera 6 together with a predetermined message for the driver who did not pay the toll despite displaying the payment request on the warning display unit 7. The warning image display unit 8 displays the appearance image of the target vehicle. Further, the license plate number displayed on the warning display unit 7 may be displayed on the warning display unit 8.
[0099]
The warning control device 21 performs a payment operation of the toll in the collection area 3 in response to the driver who has not paid the toll in the collection area 2 displaying the second payment request on the warning display unit 8. If the driver determines that the vehicle has passed through the collection area 3 without paying the toll, the license plate number of the vehicle that has passed is stored.
[0100]
Thereafter, information such as the license plate number of the vehicle that has passed through the collection area 3 without paying a fee is provided to a manager who manages the road 1 at a predetermined timing.
[0101]
As shown in FIG. 1, the vicinity of the gantry 2 and the gantry 3 is the upstream side, and the vicinity of the gantry 4 downstream of the road 1 is the downstream side.

To control. Details of the processing of the control unit 41 will be described later with reference to a flowchart.
[0104]
The transmission / reception control unit 42 controls the operation of the antenna 9 and transmits / receives various information to / from the in-vehicle device 32 of the vehicle 31 traveling in the collection area 1. Information transmitted from the in-vehicle device 32 and received by the antenna 9 is output to the fee collection processing unit 45 via the transmission / reception control unit 42.
[0105]
Similar to the transmission / reception control unit 42, the transmission / reception control unit 43 and the transmission / reception control unit 44 control the antenna 10 and the antenna 11, respectively, and communicate with the in-vehicle device 32 of the vehicle 31 traveling in the collection area 2 and the collection area 3. I do.
[0106]
The toll collection processing unit 45 collects a toll for the vehicle 31 based on information transmitted from the in-vehicle device 32 and supplied via any of the transmission / reception control units 42 to 44. In addition, the toll collection processing unit 45, when the toll for the road 1 is calculated by the distance system, based on the information transmitted from the in-vehicle device 32 (information on the identification information of the entrance gate, etc.) The toll of the vehicle 31 is calculated, the transmission / reception control units 42 to 44 are controlled, and processing such as transmitting the calculated toll to the in-vehicle device 32 is executed.
[0107]
The result of the collection process executed by the fee collection processing unit 45 is notified to the control unit 41.
[0108]
The license plate number extraction unit 46 captures an image photographed by the license plate photographing camera 5 and binarizes the image, for example, in front of the gantry 2 (a point upstream of the gantry 2 by a predetermined distance). The number shown on the license plate of the vehicle 31 traveling on the road is extracted. The license plate number extracted by the license plate number extraction unit 46 is notified to the control unit 41.
[0109]
The image processing unit 47 captures an image photographed by the vehicle appearance photographing camera 6, analyzes it, and determines whether or not a vehicle exists in the photographed range (whether or not the vehicle has entered the collection area 1). judge. When the image processing unit 47 determines that the vehicle has entered the collection area 1, the image processing unit 47 notifies the control unit 41 of the determination.
[0110]
The display control unit 48 controls the warning display unit 7 based on an instruction from the control unit 41, and the license plate extracted by the license plate number extraction unit 46 for a driver who does not pay the toll in the collection area 1. A predetermined message including a number is displayed on the warning display unit 7 as a payment request.
[0111]
The display control unit 49 controls the warning display unit 8 based on an instruction from the control unit 41, and sends a message requesting the payment to the warning display unit 8 to a driver who does not pay the toll in the collection area 2. Display. Further, the display control unit 49 displays the message on the warning display unit 8 and displays the vehicle appearance image captured by the image processing unit 47 on the vehicle appearance image display unit 8A.
[0112]
The passing vehicle information storage unit 50 stores information on a vehicle that has passed through the collection area 3 without paying the toll even though the warning display unit 8 has requested payment of the toll. Specifically, the passing vehicle information storage unit 50 stores information such as the license plate number of the vehicle that has passed, the time of passage, or the appearance image of the vehicle.
[0113]
Next, the processing of the warning control device 21 that controls the warning system of FIG. 1 will be described with reference to the flowcharts of FIGS. 3 and 4.
[0114]
In step S <b> 1, the image processing unit 47 acquires an image photographed by the vehicle appearance photographing camera 6. Then, in step S2, the image processing unit 47 analyzes the image acquired in step S1 and detects, for example, a vehicle entering the collection area 1 by referring to images of a plurality of continuous frames. For example, as shown in FIG. 1, when the vehicle 31 enters the collection area 1, the vehicle 31 moving by a predetermined distance is captured in a plurality of continuous images.
[0115]
In step S3, the image processing unit 47 determines whether there is a vehicle, that is, whether there is a vehicle that has entered the collection area 1, based on the analysis result of step S2, and there is no vehicle. If it is determined, the process is terminated.
[0116]
On the other hand, if it is determined in step S3 that the vehicle is present, the image processing unit 47 notifies the control unit 41 of the determination. When the image processing unit 47 notifies that the vehicle exists, the control unit 41 controls the license plate number extraction unit 46 so as to extract the detected license plate number of the vehicle.
[0117]
In step S4, the license plate number extraction unit 46 acquires an image photographed by the license plate photographing camera 5 based on an instruction from the control unit 41, proceeds to step S5, and binarizes it. The license plate number of the detected vehicle is extracted. Information on the license plate number extracted by the license plate number extraction unit 46 is output to the control unit 41.
[0118]
In step S <b> 6, the toll collection processing unit 45 controls the transmission / reception control unit 42, communicates with the in-vehicle device 32 mounted on the vehicle 31, and executes toll collection processing.
[0119]
For example, when the toll is fixed, the driver of the vehicle 31 performs a predetermined payment operation such as inserting a prepaid card into the in-vehicle device 32 when entering the collection area 1 of FIG. Information representing the input amount is transmitted from the antenna of the in-vehicle device 32, received by the antenna 9, and supplied to the fee collection processing unit 45 via the transmission / reception control unit 42.
[0120]
Further, when the toll is a distance-based system that varies depending on the travel distance, a detection signal of the vehicle 31 (on-vehicle device 32) is always radiated from the antenna 9 to the collection area 1 and is received. For example, identification information indicating an entrance gate of the vehicle 31 is transmitted from the in-vehicle device 32. The fee collection processing unit 45 that has received the identification information of the entrance gate via the antenna 9 and the transmission / reception control unit 42 calculates the toll for the vehicle 31 and transmits (replies) it to the in-vehicle device 32. In the in-vehicle device 32, since the calculated fee is displayed on a predetermined display unit, the driver can confirm the fee.
[0121]
In step S7, the fee collection processing unit 45 determines whether or not the fee has been collected. If it is determined that the fee has been collected, the fee collection processing unit 45 notifies the control unit 41 of the collection and ends the processing.
[0122]
On the other hand, if it is determined that the vehicle has passed through the collection area 1 (within the communication range of the antenna 9) without paying the toll, or the amount information is transmitted, but the amount is not enough for the toll If it is determined, the fee collection processing unit 45 determines in step S7 that the fee has not been collected, and notifies the control unit 41 of it.
[0123]
In step S8, the control unit 41 controls the display control unit 48 to display a predetermined message including the license plate number extracted by the license plate number extraction unit 46 at a timing when the target vehicle approaches the gantry 3 as a warning display unit. 7 is displayed. For example, as shown in FIG. 1, a message (payment request) such as “Please perform the vehicle payment operation for the license plate 12-34” is displayed on the warning display unit 7.
[0124]
In step S9, the toll collection processing unit 45 controls the transmission / reception control unit 43 to execute a toll collection process for vehicles traveling in the collection area 2. In step S10, is the toll collected? Determine whether or not.
[0125]
For example, when the driver who has confirmed the payment request displayed on the warning display unit 7 performs the predetermined payment operation as described above in the collection area 2 and thereby determines that the toll has been collected in step S10, The fee collection processing unit 45 notifies the control unit 41 of this, and ends the processing.
[0126]
On the other hand, for example, if the driver does not notice it even though the payment request is displayed on the warning display unit 7 and the vehicle comes out of the collection area 2 without paying the toll, in step S10, the fee collection is performed. The processing unit 45 determines that the fee has not been collected, and notifies the control unit 41 of it.
[0127]
In step S <b> 11, the control unit 41 controls the display control unit 49 to cause the warning display unit 8 to display a message requesting payment of the toll at the timing when the target vehicle approaches the gantry 4. In addition, the control unit 41 supplies the vehicle appearance image supplied from the image processing unit 47 to the display control unit 49 and causes the vehicle appearance image display unit 8 </ b> A of the warning display unit 8 to display the vehicle appearance image.
[0128]
The appearance of a vehicle has various characteristics such as shape, size, and color. The vehicle driver pays attention to the display of the warning display unit 8 by displaying the appearance of the vehicle he / she is driving and is familiar with the features of the external appearance. Therefore, the toll payment request can be clearly transmitted to the driver of the vehicle.
[0129]
For example, as shown in FIG. 1, the warning display unit 8 displays a message having a tone (command form) stronger than the message displayed on the warning display unit 7 such as “execute payment operation”.
[0130]
In step S <b> 12, the toll collection processing unit 45 controls the transmission / reception control unit 44 to execute toll collection processing with the vehicle traveling in the collection area 3.
[0131]
In step S13, the fee collection processing unit 45 determines whether or not the fee has been collected. If it is determined that the fee has been collected, the fee collection processing unit 45 notifies the control unit 41 of the collection and ends the processing.
[0132]
On the other hand, if it is determined in step S13 that the vehicle has passed through the collection area 3 without paying a fee, the fee collection processing unit 45 proceeds to step S14 and the license plate number extracted by the license plate number extraction unit 46. Alternatively, information such as the appearance image of the vehicle acquired by the image processing unit 47 is stored in the passing vehicle information storage unit 50 in association with the passing time.
[0133]
The information stored in the passing vehicle information storage unit 50 is transmitted at a predetermined timing to, for example, a management center that manages tolls on the road 1. Then, for the driver of the vehicle that has passed through the toll gate without paying the toll, the management center charges the toll by mail or the like.
[0134]
As described above, even if you are not aware of the payment request for the first toll, the request is made again, so you are not paying the toll compared to when the payment request is made only once. Can be surely noticed by the driver. In the first payment request, a license plate number and a predetermined message are displayed. In the second payment request, an appearance image and a stronger tone message are displayed than in the first request. As a result, it is possible to give a convincing warning from the driver who has forgotten to pay the toll.
[0135]
In the above, it is said that the payment request for the toll is made up to twice. However, by providing a plurality of warning display sections etc., it is possible to make the driver who does not pay the toll pay more certainly. it can. In this case, for example, for a driver who has displayed the second payment request on the warning display unit 8 but does not notice that the toll has not been paid, as a third payment request, for example, In addition to the second payment request (vehicle appearance image and message), a warning announcement or the like may be output from a microphone provided at a predetermined position.
[0136]
FIG. 5 is a diagram showing another configuration example of the warning system to which the present invention is applied. This warning system has basically the same configuration as the warning system shown in FIG. 1, and the same parts as those in FIG. 1 are denoted by the same reference numerals.
[0137]
In this warning system, a gantry 61 is further provided between the gantry 3 and the gantry 4 provided with the warning display portions 7 and 8 shown in FIG. A camera 62 and a vehicle appearance photographing camera 63 are installed.
[0138]
The warning control device 21 inquires of the in-vehicle device 32 of the vehicle 31 traveling in the collection area 2 whether or not the toll has already been paid, and a vehicle that has not yet paid the toll collects without paying the toll. When the vehicle passes through the area 2, a payment request is displayed on the warning display unit 8 for the vehicle.
[0139]
As a result, the vehicle that is the subject of the payment request can be identified more reliably, and the payment request can be prevented from being displayed for the vehicle that has already paid the toll.
[0140]
Further, the warning control device 21 stores the license plate number of the vehicle that has passed through the collection area 1 without paying the toll in a predetermined storage unit, and displays a payment request on the warning display unit 8 based thereon. It may be determined whether or not.
[0141]
In this case, the warning control device 21 confirms whether or not the license plate number extracted from the image photographed by the license plate photographing camera 62 exists in the storage unit described above, and the license plate number is stored in the storage unit. Is displayed on the warning display unit 8 for a vehicle that has been stored and passes through the collection area 2 without paying a toll.
[0142]
Thus, by confirming whether or not the vehicle traveling in the collection area 2 has already paid the toll, it is possible to more reliably identify the target vehicle and present a payment request.
[0143]
FIG. 6 is a block diagram illustrating a configuration example of the warning control device 21 of FIG.

[0156]
In step S <b> 45, the image processing unit 72 acquires an image (vehicle appearance image) taken by the vehicle appearance photographing camera 63 and outputs it to the control unit 41.
[0157]
In step S46, the toll collection processing unit 45 controls the transmission / reception control unit 43 to perform toll collection processing with a vehicle traveling in the collection area 2. In step S47, the toll collection processing unit 45 determines whether or not a toll has already been collected from the vehicle. If it is determined that the toll has been collected, the processing is terminated.
[0158]
For example, a flag indicating that is set in a predetermined memory of the in-vehicle device 32 that has paid the toll in the collection area 1, and the toll collection processing unit 45 has already collected the toll based on the flag. It is determined whether or not.
[0159]

The warning system shown in FIG. 1 and FIG. 5 displays the payment request in stages for vehicles that do not pay the toll on the road 1, but the warning system shown in FIG. This is a step-by-step warning for a vehicle that is performing a reduction in its traveling speed.
[0178]
The warning system shown in FIG. 10 has basically the same configuration as the warning system shown in FIG. 1 and the like, and a gantry 102, 103, 104, and 105 is provided on the road 101.
[0179]
The gantry 102 is provided with a license plate photographing camera 106 for photographing a license plate of a vehicle traveling in front of the gantry 102 and a speed detection sensor 107 for detecting the traveling speed of the vehicle. Is provided with a warning display unit 108 for displaying a warning for a vehicle that is determined to travel exceeding a predetermined speed based on detection by the speed detection sensor 107.
[0180]
The gantry 104 detects a license plate photographing camera 109 for photographing a license plate of a vehicle traveling in front of the gantry 104, a vehicle appearance photographing camera 110 for photographing the appearance of the vehicle, and a traveling speed of the vehicle. A speed detection sensor 111 is installed, and a warning display unit 112 displays a warning for a vehicle that is determined to travel exceeding a predetermined speed based on detection by the speed detection sensor 111 on the gantry 105. Is installed.
[0181]
The operation of these license plate photographing camera 106 to warning display unit 112 is controlled by a warning control device 121 provided on the left shoulder of the road 101 in the traveling direction.
[0182]
In this example, the vehicle 131 is traveling on the road 101 in the direction indicated by the white arrow.
[0183]
FIG. 11 is a block diagram illustrating a configuration example of the warning control device 121 of FIG.
[0184]
The control unit 141 controls the overall operation of the warning control device 121 in accordance with the stored control program.
[0185]
The license plate number extraction unit 142 extracts and extracts the license plate number of the traveling vehicle from the image photographed by the license plate photographing camera 106 as in the above-described license plate number extraction unit 46 of FIG. The control unit 141 is notified of the license plate number.
[0186]
For example, the speed calculation unit 143 calculates the traveling speed of the vehicle based on light having a predetermined wavelength that is emitted from the speed detection sensor 107 and reflected back by the vehicle or the like. The wavelength of the light reflected and returned by the vehicle or the like changes due to the Doppler effect according to the traveling speed of the vehicle, and the speed detection sensor 143 detects the vehicle based on the difference between the reflected wave and the outgoing wave. Calculate travel speed.
[0187]
The display control unit 144 causes the warning display unit 108 to display a predetermined warning message or the like based on an instruction from the control unit 141. For example, the display control unit 144 causes the warning display unit 108 to display a warning message including the license plate number extracted by the license plate number extraction unit 142.
[0188]
Like the license plate number extraction unit 142, the license plate number extraction unit 145 extracts the license plate number from the image photographed by the license plate photographing camera 109, and the speed calculation unit 147 is the same as the speed calculation unit 143. Then, the traveling speed of the vehicle is calculated, and the display control unit 148 causes the warning display unit 112 to display a predetermined warning message, similarly to the display control unit 144.
[0189]
For example, as shown in FIG. 1, the warning display unit 112 includes a vehicle appearance image display unit 112 </ b> A. The vehicle appearance image display unit 112 </ b> A includes a vehicle appearance image acquired by the image processing unit 146. Is displayed. Further, the warning display unit 112 displays a warning message such as “Decrease the vehicle speed of the number plate 12-34” as shown in FIG.
[0190]
In the information storage unit 149, for example, a license plate number or an appearance image of a vehicle that does not reduce the traveling speed to a predetermined speed or less despite the warning displayed on the warning display unit 108 corresponds to the passing time of the vehicle. It is memorized.
[0191]
Next, the processing of the warning control device 121 that controls the display of warnings in the warning system of FIG. 10 will be described with reference to the flowcharts of FIGS.
[0192]
First, processing of the warning control device 121 that controls warning on the upstream side of the warning system of FIG. 10 will be described with reference to the flowchart of FIG.
[0193]
In step S81, the license plate number extraction unit 142 acquires an image photographed by the license plate photographing camera 106, and analyzes it in step S82. In step S83, the license plate number extraction unit 142 determines whether or not a vehicle exists (whether or not the vehicle is traveling in front of the gantry 102) from the analysis result in step S82. If so, the process is terminated.
[0194]
On the other hand, if the license plate number extraction unit 142 determines in step S83 that there is a vehicle, the license plate number extraction unit 142 proceeds to step S84.
[0195]
In step S84, the speed calculation unit 143 acquires an output from the speed detection sensor 107, and in step S85, calculates a traveling speed of the vehicle traveling in front of the gantry 102 based on the acquired output. As described above, for example, when the emitted light is reflected by the vehicle and returned, the traveling speed calculation unit 143 measures the traveling speed of the vehicle based on the difference between the reflected wave and the emitted wave, and controls it. 141 is output.
[0196]
In step S86, the control unit 141 determines whether or not the speed calculated in step S85 exceeds a predetermined threshold speed. If it is determined that the speed is not exceeded, the control unit 141 ends the process. On the other hand, when it is determined in step S86 that the calculated speed exceeds the predetermined threshold speed, the control unit 141 proceeds to step S87, controls the license plate number extraction unit 142, and is acquired in step S81. License plate number is extracted from the image.
[0197]
The license plate number extracted by the license plate number extraction unit 142 is supplied to the control unit 141. In step S88, the control unit 141 controls the display control unit 144, and a warning message including the supplied license plate number. Is displayed on the warning display unit 108. On the warning display unit 108, for example, a warning such as “Please reduce the vehicle speed of the license plate 12-34” as shown in FIG. 1 is displayed.
[0198]
Next, processing of the warning control device 121 that controls warning on the downstream side of the warning system of FIG. 10 will be described with reference to the flowchart of FIG. This process is executed after the vehicle is detected by the process described with reference to the flowchart of FIG.
[0199]
The processes in steps S101 to S103 are the same as the processes in steps S81 to S83 described with reference to FIG. That is, the license plate number extraction unit 145 determines whether or not the vehicle is traveling in front of the gantry 104 in step S103 based on the image photographed by the license plate photographing camera 109. If it is determined, the process proceeds to step S104.
[0200]
In step S <b> 104, the image processing unit 146 acquires an image photographed by the vehicle appearance photographing camera 110 and outputs it to the control unit 141.
[0201]
In step S105, the speed calculation unit 147 acquires the output from the vehicle detection sensor 111, and in step S106, calculates the detected traveling speed of the vehicle based on the acquired output. Information regarding the speed calculated by the speed calculation unit 147 is supplied to the control unit 141.
[0202]
In step S107, the control unit 141 determines whether or not the detected traveling speed of the vehicle exceeds a predetermined threshold speed based on the supplied speed information, and does not exceed the threshold speed. If it is determined, the process is terminated.
[0203]
On the other hand, if it is determined in step S107 that the traveling speed of the vehicle exceeds the predetermined threshold value, the control unit 141 proceeds to step S108, controls the license plate number extraction unit 145, and determines from the image acquired in step S101. The license plate number is extracted. The extracted license plate number is output to the control unit 141.
[0204]
In step S109, the control unit 141 outputs the appearance image of the vehicle acquired in step S104 and the license plate number of the vehicle extracted in step S108 to the display control unit 148, which is displayed on the warning display unit 112. Display.
[0205]
For example, based on the license plate number extracted in step S108, the control unit 141 determines that the vehicle targeted for warning by the process of step S107 is the warning target vehicle even in the upstream side (in the process of FIG. 12). It is determined whether or not the vehicle is a vehicle that has been warned (whether or not the vehicle has been warned once), and for a vehicle that makes such a second warning, as shown in FIG. An appearance image and a warning message are displayed on the warning display unit 112.
[0206]
On the other hand, the control unit 141 determines that the vehicle that has been subjected to the warning in the process of step S107 has a traveling speed between the upstream side (in the process of FIG. 10 is displayed on the warning display unit 112, the license plate number and the warning message displayed on the warning display unit 108 of FIG. 10 are displayed for the vehicle. Let
[0207]
In step S110, the control unit 141 stores information related to, for example, a license plate number and an appearance image related to the vehicle detected as generating a speed equal to or higher than a predetermined threshold in association with the time of passage. Stored in the unit 149.
[0208]
In this way, warnings for speed violations are displayed multiple times, so even if the driver of the warning target vehicle does not notice the first warning, the speed violation is more reliably committed. The driver can be made aware that
[0209]
【The invention's effect】
As described above, according to the present invention, a plurality of displays for requesting toll payment and a display for requesting suppression of traveling speed are provided, so that the driver can be more surely aware of this. Can do.
