Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a parking management device and a road-to-vehicle communication roadside system for guiding a vehicle to a predetermined position for short-range communication between roads and vehicles.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, various road-to-vehicle communication systems have been put to practical use or studied for practical use. As a typical example of road-to-vehicle communication that has been put into practical use, there is a nonstop automatic toll payment system called ETC (Electric Toll Collection System). When using this system, it is necessary to purchase a communication device dedicated to ETC and install it in a car. ETC communication devices can be broadly divided into two types. There are two types: a built-in antenna type with a built-in antenna in the communication device, and a separated type where the communication device and the antenna are separated. And place it in the specified location.
[0003]
At present, a large-capacity road-vehicle communication system that handles large-capacity data is being studied as an application of the ETC. As one of them, an ultra-narrow area cell-type road-vehicle communication system using a very narrow communication area (for example, within a radius of 1 m) is being studied. In this system, large-volume data communication is performed in a parking area such as a service area or a supermarket while a vehicle is parked.
[0004]
Also in this system, it is usual that an antenna is installed at a designated position as in the ETC described above. In this case, there is no problem if the vehicle is parked at a position where communication is possible, but if the parking position is shifted, the antenna on the vehicle side may be very out of the communication area.
[0005]
In the road-vehicle communication, for example, Patent Literature 1 discloses a technique for performing communication when a roadside (service providing side) communication area and an in-vehicle antenna are at a correct position. This is because the roadside receives in advance information on the antenna mounting position of the vehicle, that is, information on the relative distance between the vehicle position detection portion (front-wheel lower-end contact portion) and the vehicle-mounted antenna. Then, a position sensor whose distance to the roadside antenna is closest to the above-described relative distance is selected, and communication with the vehicle is started when the position sensor detects a position detection site of the vehicle.
[0006]

[0007]
[Problems to be solved by the invention]
Although the technology described in Patent Document 1 is not intended for short-range communication, even if this technology is used for short-range communication, the vehicle does not always stop reliably at the position where the sensor detects the vehicle. Absent. Therefore, it cannot be said that communication can be performed with the vehicle stopped at the correct position.
[0008]
Accordingly, the present invention has been made in view of the above points, and in a short-range communication between a road and a vehicle, guides a vehicle using a bogie according to a mounting position of the vehicle-mounted antenna in the vehicle so that the vehicle-mounted antenna enters the communication area. Aim.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 is a vehicle-mounted antenna position information obtaining means for obtaining information on a positional relationship of a vehicle-mounted antenna for short-range road-to-vehicle communication with respect to the entire vehicle, and a position information obtaining means.

[0010]
Thereby, the in-vehicle antenna position information obtaining means obtains information on the positional relationship of the in-vehicle antenna of the short-range road-to-vehicle communication with respect to the entire vehicle, and the vehicle stopping arrangement means, based on the information obtained by the position information obtaining means, Since the vehicle stop is arranged at a position where the vehicle can be stopped so that the vehicle-mounted antenna enters the communication area of the narrow-area road-to-vehicle communication, the vehicle user stops the vehicle in accordance with the vehicle stop, and the vehicle-mounted antenna is moved to the communication area. Will be included. Therefore, in the short-range communication between the road and the vehicle, the vehicle can be guided using the vehicle stop according to the mounting position of the vehicle-mounted antenna in the vehicle so that the vehicle-mounted antenna enters the communication area.
[0011]
According to a second aspect of the present invention, in the parking management device according to the first aspect, the on-vehicle antenna position information acquiring means includes information on a positional relationship of the on-vehicle antenna for narrow-area road-to-vehicle communication with respect to wheels of the vehicle. The wheelchair arranging means acquires, based on the information acquired by the position information acquiring means, arranges the wheelchair at a position where the vehicle can be stopped so that the on-vehicle antenna enters the communication area of the narrow area road-to-vehicle communication. It is characterized by the following.
[0012]
According to a third aspect of the present invention, a roadside device antenna for narrow-area road-to-vehicle communication in which a part of a parking space is a communication area and a specific part of a vehicle belonging to the first vehicle type are stopped at the position. A first vehicle stop provided at a position where an on-board antenna for short-range road-to-vehicle communication mounted on a vehicle belonging to the first vehicle type enters a communication area; and a method for identifying a vehicle belonging to the second vehicle type. A second wheel stop provided at a position such that an on-board antenna for narrow-area road-to-vehicle communication mounted on a vehicle belonging to the second vehicle type enters the communication area by stopping the vehicle at that position. This is an inter-vehicle communication roadside system.
[0013]
As a result, the vehicle belonging to the first vehicle type stops a specific part of the vehicle at the position of the first vehicle stop, so that the vehicle-mounted antenna of the vehicle belonging to the first vehicle type becomes the communication area of the roadside antenna. And the vehicle belonging to the second vehicle type stops a specific part of the vehicle at the position of the second vehicle stop, so that the vehicle-mounted antenna of the vehicle belonging to the second vehicle type communicates with the roadside device antenna. Enter the area. Therefore, the roadside-vehicle communication roadside system can guide the vehicle using the bogie according to the mounting position of the vehicle-mounted antenna in the vehicle so that the vehicle-mounted antenna enters the communication area in the short-range communication between the roadside and the vehicle. .

Next to the exit button 23, the word "exit" is specified. In addition, “parking space” is specified above the parking space button 22, and letters A, B, C, and D are displayed on each of the parking space buttons 22. This allows the user to recognize which button has which function and which parking space button 22 corresponds to which parking space.
[0034]
The operation of the entrance processing machine 7 and the like when the vehicle 8 enters the parking lot 1 configured as described above will be described below.
[0035]
FIG. 10 is a flowchart illustrating a processing configuration of a program executed by the CPU 25 immediately after the power is turned on.
[0036]
The CPU 25 stores parking space information in the RAM 27, which is information on whether or not a vehicle is parked in each parking space. The CPU 25 receives a signal from the vehicle sensor 41 of each parking space via the management network 9 and rewrites the parking space information based on the received signal in parallel with the processing of the flowchart shown in FIG. . Specifically, a vehicle is parked in a parking space corresponding to the vehicle detection sensor 41 transmitting a signal indicating that the presence of the vehicle is being detected, and the vehicle detection sensor 41 not transmitting the signal transmits the signal. The information that the corresponding parking space is vacant is written in the RAM 27 as parking space information.
[0037]
Hereinafter, the processing of FIG. 10 will be described. In step 105, the CPU 25 outputs a video signal to the display device 20 to display the screen shown in FIG. Thus, it is possible to urge the user of the vehicle 8 who wants to enter the parking lot 1 to press the entry button 16.
[0038]
Then, in step 110, it is determined whether or not the entrance button 16 has been pressed, that is, whether or not the entrance button 16 has been turned on.
[0039]
If it is on, the process proceeds to step 115, where the user of the vehicle 8 is asked for vehicle information. Specifically, by displaying the screen shown in FIG. 11B on the display 20 and outputting an audio signal to the speaker 21, the speaker 21 outputs an audio such as “Please input vehicle information”. Is performed.
[0040]
Next, at step 120, it is determined whether the sedan button 17 or the wagon button 18 (hereinafter referred to as a vehicle information button) has been pressed, that is, whether the vehicle information button has been turned on. Return.
[0041]
If it is on, the process proceeds to step 125, where a search for a parking space is performed. Specifically, the screen shown in FIG. 11C is displayed on the display device 20, and the vehicle space information described above is read.
[0042]
Then, in step 130, it is determined whether or not there is a space to park based on the read parking space information. If there is no space, that is, if all parking spaces are in use, the process returns to step 125. As described above, if there is no empty space, the search process is repeated until an empty space is created.
[0043]
If there is a parking space, the process proceeds to step 135, in which the wheel is lifted. More specifically, one of the vacant parking spaces is assigned, via the driver 28 and the management network 9, to one wheel stopper elevating device 5 having the highest priority set in advance (for example, A → B → C → D). To send a signal. If the vehicle information button detected to be pressed in step 120 is the sedan button 17, the signal to be transmitted is a signal for causing the wheel-chock lifting device 5 to lift two of the sedan wheel-chock 10. If the vehicle information button whose depression is detected in step 120 is the wagon button 18, the signal to be transmitted is a signal for causing the wheel-chock lifting device 5 to lift the two wagon wheel chock 11.
[0044]
The wheelchair lifting / lowering device 5 that has received this signal controls the motor based on the signal, and lifts the sedan wheelchair 10 or the wagon wheelchair 11.
[0045]
After executing Step 135, the CPU 25 advances the processing to Step 145. In step 145, the user of the vehicle 8 is requested to specify and confirm a parking space. That is, the display 20 displays the screen shown in FIG. 11D on the display 20, outputs a voice notification of a parking space designation such as “Can park in space B” to the speaker 21, and confirms if it is all right. Please press the button. "
[0046]
Then, the process proceeds to step 150, and it is determined whether or not the confirmation button has been pressed, that is, whether or not the button is on. If not, the process returns to step 145. If it is on, the process proceeds to step 155 to perform a process of opening the entrance gate. Specifically, a screen shown in FIG. 11E is displayed on the display 20, and a control signal for opening the entrance gate 6 is transmitted to the entrance gate 6 via the driver 28 and the management network 9. The entrance gate 6 receiving this control signal performs an operation of opening the gate.
[0047]
When the entrance gate 6 is opened, the user of the vehicle 8 causes the vehicle 8 to enter the parking lot 1.
[0048]
In step 160 following step 155, the CPU 25 determines whether the vehicle 8 has entered the parking lot 1 through the entrance gate 6. Specifically, it is determined whether or not a signal indicating that the vehicle is in front of the entrance gate 6 is received from the vehicle sensor 61. Then, this determination processing is repeated until the vehicle 8 passes through the entrance gate 6, that is, until the vehicle 8 is not in front of the entrance gate 6.
[0049]
When the vehicle 8 has passed the entrance gate 6, the process proceeds to step 165, where a control signal for closing the gate is transmitted to the entrance gate 6, whereby the entrance gate 6 closes the gate. Then, the process returns to step 105, and a display for urging the next entry vehicle to press the entry button 16 is performed.
[0050]
As described above, the entry processing machine 7 notifies the user of the vehicle 8 of the designation of the parking space, so that the vehicle 8 is guided to an appropriate parking space. Then, the user stops the vehicle 8 with the front wheel of the vehicle 8 being in contact with the raised sedan wheel chock 10 or the wagon wheel chock 11. FIGS. 12 and 13 show side views of the parking space and the vehicle 8 in this state. FIG. 12 is a diagram when the vehicle 8 is a sedan vehicle, and FIG. 13 is a diagram when the vehicle 8 is a wagon vehicle.
[0051]
The vehicle-mounted antenna 12 of the vehicle 8 is installed near the windshield of the vehicle as described above. Therefore, the positional relationship of the vehicle-mounted antenna 12 with respect to the entire vehicle differs between the sedan vehicle and the wagon vehicle. More specifically, in the case of a wagon car, the windshield is located directly above the front wheel, whereas in the case of a sedan car, the windshield is located behind the front wheel, so the sedan and wagon cars have the front wheel The positional relationship between the antenna and the vehicle-mounted antenna 12 is different. Therefore, in order for the in-vehicle antenna 12 to enter the area of the roadside device antenna 4, it is necessary to change the position where the vehicle wheel stops depending on the vehicle type.
[0052]
As shown in FIGS. 12 and 13, the sedan car 8 is parked with the front wheels stopped in front of the wagon car 8. In this way, the on-vehicle antenna 12 in the vehicle 8 has the communication area of the roadside machine antenna 4, that is, the roadside machine antenna 4 at the top, in the case of a sedan car and a wagon car, and has a ground radius in front of the parking space. It enters a conical space region having a bottom surface of about 1 m.
[0053]
Thereby, the entrance processor 7 obtains information on the positional relationship of the in-vehicle antenna 12 of the short-range communication with respect to the entire vehicle, specifically, information on the positional relationship with the front wheels, that is, information on whether the vehicle is a sedan vehicle or a wagon vehicle, Further, based on the acquired information, the wheel stopper is arranged at a position where the vehicle can be stopped so that the vehicle-mounted antenna 12 enters the communication area of the roadside device antenna 4 for the short-range communication. By stopping the vehicle 8 by applying the front wheel of the vehicle 8 to the wheel stopper, the vehicle-mounted antenna 12 enters the communication area of the roadside unit antenna 4. Therefore, in the short-range communication between the road and the vehicle, the vehicle can be guided using the vehicle stop according to the mounting position of the vehicle-mounted antenna in the vehicle so that the vehicle-mounted antenna enters the communication area.
[0054]
FIG. 14 shows, as a flowchart, a process of the CPU 35 for leaving the vehicle 8 from the parking lot 1. This processing is based on a program executed by the CPU 35 immediately after the exit processing machine 2 is activated by turning on the power.
[0055]
The CPU 35 stores parking space information in the RAM 27, which is information on whether or not the vehicle is parked in each parking space. In parallel with the processing of the flowchart shown in FIG. 14, the CPU 35 receives a signal from the vehicle sensor 41 of each parking space via the management network 9 in the same manner as the CPU 25 of the entrance processing machine 7, and receives this signal. This parking space information is rewritten based on the signal that has been given. Hereinafter, the processing of FIG. 14 will be described. In step 205, the CPU 35 causes the screen display 20 to display the screen shown in FIG. Thus, the user of the vehicle 8 who wants to leave the parking lot 1 can be prompted to press any one of the parking space buttons 22.
[0056]
In step 210, it is determined whether or not the parking space button 22 has been pressed, that is, whether or not any of the parking space buttons 22 has been turned on. If not, the process returns to step 205.
[0057]
If it is on, the process proceeds to step 215, and requests the user of the vehicle 8 to press the exit button 23. Specifically, the screen shown in FIG. 15B is displayed on the screen display 20, a voice signal is output to the speaker 21, and a voice such as “press the exit button” is output.
[0058]
Next, in step 220, it is determined whether or not the exit button 23 has been pressed, that is, whether or not the exit button 23 has been turned on. If not, the process returns to step 215.
[0059]
If it is on, the process proceeds to step 225, and it is checked whether the parking space detected in step 210 is actually empty. Specifically, the display 20 displays the screen shown in FIG. 15C, and reads the vehicle space information described above.
[0060]
Then, in step 230, it is determined whether or not the parking space is empty based on the read parking space information. If not, the process returns to step 225. As described above, if the parking space is not actually vacant, the confirmation processing is repeated until the parking space becomes vacant.
[0061]
If the parking space is vacant, the process proceeds to step 235 and notifies the user of the vehicle 8 of leaving permission. Specifically, the screen shown in FIG. 15D is displayed on the display device 20, and the speaker 21 outputs a sound such as “the exit gate is open” to the effect that the vehicle can exit.
[0062]
Then, in step 240, a process of opening the exit gate 3 via the management network 9 is performed. Specifically, a control signal for opening the exit gate 3 is transmitted to the exit gate 3 via the driver 28 and the management network 9. The exit gate 3 receiving this control signal performs an operation of opening the gate.
[0063]
When the exit gate 3 opens, the user of the vehicle 8 causes the vehicle 8 to exit the parking lot 1.
[0064]
In step 245 following step 240, the CPU 35 determines whether or not the vehicle 8 has passed through the exit gate 3 and exited out of the parking lot 1. Specifically, it is determined whether or not a signal indicating that the vehicle is in front of the exit gate 3 is received from the vehicle sensor 31. Then, this determination processing is repeated until the vehicle 8 passes through the exit gate 3, that is, until the vehicle 8 is no longer in front of the exit gate 3.
[0065]
When the vehicle 8 has passed the exit gate 3, the process proceeds to step 250, where a control signal for closing the gate is transmitted to the exit gate 3, whereby the exit gate 3 closes the gate. Then, the process returns to step 205 to display a message prompting the next leaving vehicle to press the parking space button 22.
[0066]
In this way, the process of leaving the vehicle 8 from the parking lot 1 is performed.
[0067]
(2nd Embodiment)
FIG. 16 shows an overall view of a parking lot 51 according to the second embodiment of the present invention. This parking lot 51 is different from the parking lot 1 of the first embodiment in its configuration in that the wheel stopper raising / lowering device 5 is replaced by a wheel stopper device 13 and the entrance processing machine 7 is replaced by an entrance processing machine 57. It is a point. In this embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted.
[0068]
FIG. 17 is a perspective view of one of the parking spaces in the parking lot 51. The wheel stopper 13 includes a sedan wheel stopper 14 and a wagon wheel stopper 15. The sedan wheel chock 14 is a groove-shaped depression provided in front of the wagon wheel chock 15, that is, closer to the head of the vehicle that has entered the parking lot, and the wagon wheel chock 15 is provided behind the sedan wheel chock 14. It is a groove-shaped depression. The roadside machine antenna 4, the sedan wheelchair 14, and the wagon wheelchair 15 constitute a roadside-vehicle communication roadside system.
[0069]
FIG. 18 shows a cross-sectional view taken along the line DD of FIG. The wheel stopper 13 and the sedan wheel stopper 14 have such a depth that an occupant can feel a clear descent when the wheel enters this depression, and the vehicle can freely move back and forth without resistance when the wheel is inserted into the depression. It has a width that makes it impossible to move. For example, the depth is 10 cm and the width is 20 cm.
[0070]
FIG. 19 shows the configuration of the entrance processing machine 57. The entrance processor 57 differs from the entrance processor 7 of the first embodiment in that the entrance processor 7 has no sedan button 17 and wagon button 18.
[0071]
During the operation of the entrance processing machine 57, the CPU 45 stores parking space information, which is information as to whether or not a vehicle is parked in each parking space, in the RAM 27, similarly to the CPU 25 of the entrance processing machine 7, and stores each parking space. And receives the signal from the vehicle sensor 41 via the management network 9 and rewrites the parking space information based on the received signal.
[0072]
During operation, the CPU 45 performs the processing shown in FIG. 20 in addition to the above processing.

As a result, the sedan vehicle stops a specific part of the vehicle, that is, a front wheel with the sedan wheel stopper 14, so that the vehicle-mounted antenna 12 of the sedan vehicle enters the communication area of the roadside machine antenna 4, and the wagon vehicle does not. By stopping a specific part of the vehicle, that is, a front wheel, with the wagon wheel stopper 15, the vehicle-mounted antenna 12 of the wagon vehicle enters the communication area of the roadside machine antenna 4. Therefore, the roadside-vehicle communication roadside system can guide the vehicle using the bogie according to the mounting position of the vehicle-mounted antenna in the vehicle so that the vehicle-mounted antenna enters the communication area in the short-range communication between the roadside and the vehicle. .
[0079]
The operation of the exit processor 2 when the vehicle exits the parking lot 51 is the same as in the first embodiment.
[0080]
In the first and second embodiments of the present specification, the entrance processing machine 7 forms a parking management device.
[0081]
The first vehicle type is a sedan, and the second vehicle type is a wagon. The sedan wheel chocks 10, 14 are first wheel chocks, and the wagon wheel chocks 11, 15 are second wheel chocks. However, there is no need to use only two types of vehicles in this way, for example, there are three or more types such as sedans, wagons, and trucks. By stopping a specific part of the vehicle to which each type belongs at that position, Each of the bollards may be provided at a position where an on-board antenna for narrow-area road-to-vehicle communication mounted on a vehicle belonging to the vehicle type enters a communication area of a roadside machine antenna for narrow-area road-to-vehicle communication.
[0082]
Further, in the present embodiment, a specific part of the vehicle for stopping the vehicle 8 is used as a front wheel of the vehicle, and a wheel stop is used as a wheel stop. However, this means that the vehicle 8 is moved at a predetermined specific position of the vehicle. Anything that stops is sufficient, for example, a specific part may be the front end of the vehicle.
[0083]
In the first embodiment, the processing of steps 115 and 120 in FIG. 10 constitutes on-vehicle antenna position information acquisition means for acquiring information on the positional relationship of the on-vehicle antenna for short-range road-to-vehicle communication with respect to the entire vehicle.
[0084]
Further, the processing of step 135 is based on the information acquired by the position information acquisition means, and the vehicle stop is arranged at a position where the vehicle can be stopped so that the on-vehicle antenna enters the communication area of the narrow area road-to-vehicle communication. Constituting means.
