Abstract

(57) [Summary] [Problem] A vehicle waiting for an emergency vehicle to pass is
Actually, if a route search is performed in time to arrive at a desired arrival time using a car navigation system or the like, the arrival time originally scheduled is affected by the waiting time. In addition, even if the vehicle is stopped, it will hinder the operation of the emergency vehicle as long as the vehicle is on the route of the emergency vehicle. A general vehicle is identified as an emergency vehicle based on movement information (planned route, traveling direction, speed, position information, etc.) of a vehicle that preferentially occupies a road, such as an emergency vehicle, and information on a current position and a destination of a general vehicle. A route guidance device for searching for a route that does not pass in front of the vehicle or a route in which a general vehicle does not exist within a predetermined range centered on an emergency vehicle.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a technique for searching a route to a destination while avoiding a road occupant.

[0002]

2. Description of the Related Art Conventionally, it has been necessary to preferentially drive an emergency vehicle such as an ambulance in an emergency. Therefore, Japanese Unexamined Patent Publication No. 2000-331287 discloses a device that visually displays the positions of the own vehicle and the emergency vehicle and the planned route of the emergency vehicle on a map screen such as a car navigation system. Alternatively,
Japanese Unexamined Patent Publication No. 10-134299 discloses a road system in which a lamp for emergency display is provided on a center line of a road, and when the road becomes a route of an emergency vehicle, the lamp is turned on to inform a general vehicle. There is.

Then, the driver of the general vehicle can know the position of the emergency vehicle, the planned traveling route, and the like by using the vehicle-mounted terminal and the traffic infrastructure. As a result, the general vehicle was aware of the approach of the emergency vehicle and waited until the emergency vehicle passed, responding by cooperating with the priority running of the emergency vehicle.

[0004]

However, it is assumed that a vehicle waiting for an emergency vehicle to pass an actual route search using a car navigation system or the like so as to arrive at a desired arrival time. Then, the waiting time affects the originally scheduled arrival time. Moreover, even if the vehicle is stopped as long as it is on the route of the emergency vehicle (the more general vehicles are waiting), it will interfere with the operation of the emergency vehicle to some extent in the end, etc. There are challenges.

[0005]

In order to solve the above-mentioned problems, the present invention provides movement information (scheduled route, traveling direction, speed, position information, etc.) of a vehicle such as an emergency vehicle that preferentially occupies a road.
And from the information of the (general) vehicle's current position and destination,
(General) A route where the vehicle does not pass in front of an emergency vehicle or within a predetermined range centered on the emergency vehicle (General)
(EN) Provided is a route guidance device for searching a route in which no vehicle exists.

As described above, according to the present invention, a general vehicle can search and travel on a route that does not obstruct the planned route of the emergency vehicle, so that it is not necessary to wait for the emergency vehicle to pass through. In addition, according to the present invention, a general vehicle selects and runs a route avoiding a planned route in advance,
Emergency vehicles can arrive more quickly at their destination.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to FIGS. The present invention should not be narrowly interpreted by these embodiments.

<First Embodiment>

(Concept of Embodiment 1)

FIG. 1 is a diagram showing the concept of route guidance by the route guidance device of this embodiment. “●” (0101) in this figure indicates the current position of the user's own vehicle. In order to reach the destination "◎" (0102), the user uses the route guidance device to search for a route in the same way as a normal car navigation system, turn left at the five-way intersection and proceed west on the Chuo Expressway (see the solid line arrow in the figure). )). But at this time,
An accident occurred west of the Chuo Expressway, and an ambulance (0103) indicated by a "☆" passed on the dashed arrow on the Chuo Expressway.

By the way, when an emergency vehicle comes from the rear, it is usually necessary to stop at a shoulder or the like to make way for the emergency vehicle. Therefore, the vehicle of this user must also wait on the shoulder of the road, etc. until the emergency vehicle passes when he / she travels the route (central road) searched first. But that would be a loss of time. Therefore, the route guidance device of the present embodiment determines a detour route (“solid arrow” in the figure) that avoids the front of the planned route of the ambulance from the ambulance operation information, the current position of the own vehicle, and the destination information. The detour route is displayed on the display screen, and the user is instructed to follow the detour route. In this way, the user's vehicle can travel to its destination through a route that does not waste much time and does not prevent the ambulance from reaching the accident scene early.

(Structure of Embodiment 1)

FIG. 2 is a diagram showing an example of functional blocks of the route guidance device of this embodiment. As shown in this figure, the “route guidance device” (0200) of this embodiment
Has a "vehicle operation information acquisition unit" (0201), a "road occupant movement information acquisition unit" (0202), and a "front avoidance information acquisition unit" (0203).

However, the route guidance device according to the present embodiment is not limited to the embodiment that is installed in a vehicle like the conventional car navigation system as described in the above concept, but is a business that provides such a route guidance service. It may be a person's server device. In the following description of this embodiment, these two embodiments will be assumed and described.

The "vehicle operation information acquisition unit" (0201)
It has a function to acquire vehicle operation information. "Vehicle operation information" refers to information about the operation of a vehicle, such as current position information, speed information, destination and direction information of a vehicle targeted for route guidance, or planned route information that has already been searched. To be

Further, as described above, if this route guidance device is implemented in a vehicle, the "vehicle operation information acquisition unit" can be operated by an operator from an input device such as a keyboard or a touch panel. It suffices to acquire the vehicle operation information input by. Further, if this route guidance device is implemented in the form of a server device, the "vehicle operation information acquisition unit" may use the vehicle operation information transmitted from the terminal of each vehicle through the internet network or the wireless network, for example, as vehicle identification information. It may be received and acquired by the receiving unit in association with.

"Road occupant movement information acquisition unit" (020
2) has a function of acquiring road occupant movement information.
“Road occupant movement information” refers to information regarding movement of the road occupant. The "road occupant" means a moving body that preferentially occupies the road over general vehicles including large vehicles such as trucks and buses, and examples thereof include an ambulance, a fire engine, and a police car. In addition, "moving" includes staying on the spot. In other words, as a road occupant,
Other examples include construction sites and inspection sites by police. Therefore, as specific examples of road occupant movement information, ambulance operation information (current location information, speed information, destination and direction information, planned route information, etc.), construction site location information and scheduled end (removal) ) Examples include time information.

In addition, this "road occupant movement information acquisition unit" is provided for both the route guidance device and the server device mounted on the vehicle.
Receives the road occupant movement information transmitted from, for example, VICS (Road Traffic Information and Communication System) at the receiving unit,
Just get it.

Then, using the vehicle operation information and the road occupant movement information thus obtained, the route guidance device determines whether or not the vehicle and the ambulance meet each other after a predetermined time, and runs on the same route. You can judge whether it is supposed to be done.

The "forward avoidance information acquisition unit" (0203)
It has a function of acquiring forward avoidance information based on the vehicle operation information acquired by the vehicle operation information acquisition unit (0201) and the road occupant movement information acquired by the road occupant movement information acquisition unit (0202). The “forward avoidance information” refers to information for the vehicle to run while avoiding ahead of the route of the road occupant.
For example, map information or voice information indicating a route that can be operated while avoiding the route ahead of the road occupant, or "4
If you drive at 0 km, you will be able to follow the route just after the ambulance has passed. "

FIG. 3 is a schematic diagram for explaining an example of forward avoidance information. As shown in this figure, the vehicle "●" (0301) to be route-guided is traveling on the route indicated by the arrow toward the destination. However, at this time, the ambulance "☆" (0302) is also scheduled to pass through the four corners on the route (arrow) of the vehicle "●" to the accident site. At this time, the route guidance device uses the planned route information and speed information of the vehicle, and the planned route information and speed information of the ambulance, and when the vehicle "●" passes through these four corners, the ambulance "☆" is still on. Judges that the vehicle has not reached the four corners, that is, the vehicle “●” passes in front of the ambulance “☆”. Therefore, this route guidance device uses the current position information, destination information, speed information of the vehicle, and route information and speed information of the ambulance to allow the vehicle "●" to pass behind the ambulance "☆". Search for routes (arrows) to various destinations. The "forward avoidance information acquisition unit" acquires map information, voice information, and the like indicating the route searched in this way.

However, the front of the route of a road occupant that does not operate such as an inspection or a construction site is a space defined below. First, it is assumed that there is a road occupant such as a construction site on the route from the current position of the vehicle to the destination. At this time, when the vehicle travels along the route to reach the destination,
The vehicle will inevitably pass over the road occupant. Then, when passing through, the predetermined space on the route around the road occupant in the direction in which the vehicle enters the road occupant is the front of the route of the road occupant that does not operate such as inspection or construction site. .

FIG. 4 is a schematic diagram for explaining an example of the front of the route in this road occupant that is not in operation. According to the above definition, the space (0402) indicated by diagonal lines in the figure is shown.
However, this is the front of the route at this construction site. Therefore, the vehicle "●" (0401) does not have to bother to pass through the construction site if it avoids the front of the route (0402) and passes through the solid arrow ().

In the case of a route guidance device mounted on a vehicle, front avoidance information is output from a display or a speaker, which is an output unit, based on the front avoidance information acquired by the "front avoidance information acquisition unit". . Further, in the case of the server device, the front avoidance information acquired by the “front avoidance information acquisition unit” is transmitted from the transmission unit (for example, specified by the vehicle identification information described above) to each vehicle.

In this way, the driver of the vehicle can know the route avoiding the front of the road occupant, and the vehicle itself and the road occupant can smoothly operate and work. Also, in this way, if the number of vehicles that should be in the front passes through another route, the ambulance can speed up without worrying about the accident, and it is possible to express to the accident site. become.

(Processing flow of the first embodiment)

FIG. 5 is a flowchart showing an example of the processing flow of the route guidance device of this embodiment. As shown in this figure, first, vehicle operation information is acquired (step S0501). Also, the road occupant movement information is acquired (step S0502). Finally, the step S
The vehicle operation information acquired in 0501 and the step S0
Forward avoidance information is acquired based on the road occupant movement information acquired in 502 (step S0503).

The "process flow" described in this specification
An example of the procedure is a method, a program, a computer-readable recording medium recording the program,
Can be implemented as. In addition, the device described in the present specification includes a program for realizing this, or a computer-readable recording medium recording the program. (The same applies to the description in the following embodiments.)

(Simple description of the effect of the first embodiment)

As described above, the route guidance device according to the present embodiment can obtain information such as a route and an hour speed at which the vehicle can travel while avoiding the route ahead of the road occupant. By outputting the acquired forward avoidance information to the driver, the driver can head to the destination without making the vehicle stand by on the road shoulder. In addition, since there is no (general) vehicle in front of the road occupant, an ambulance can be rushed to the site, and if it is a construction site, the time and effort of traffic control can be reduced and the construction can be carried out smoothly. .

<Second Embodiment>

(Concept of Embodiment 2)

Similar to the first embodiment, the present embodiment is a route guidance device for determining, for example, a detour route that avoids a planned route for an ambulance and presenting the user to run on the detour route. The point different from the first embodiment is that a route for preventing (general) vehicles from entering a predetermined range of the ambulance is provided to the drivers of those vehicles instead of the route avoiding the forward course of the ambulance or the like. This is a point to be presented.

(Structure of Embodiment 2)

FIG. 6 is a diagram showing an example of functional blocks of the route guidance device of this embodiment. As shown in this figure, the “route guidance device” (0600) of this embodiment
Has a "vehicle operation information acquisition unit" (0601), a "road occupant movement information acquisition unit" (0602), and a "surrounding avoidance information acquisition unit" (0603).

However, the route guidance device of the present embodiment may also be an embodiment mounted on a vehicle or a server device, as in the first embodiment.

The description of the "vehicle operation information acquisition unit" and the "road occupant movement information acquisition unit" of the present embodiment is the same as that of the first embodiment, and will be omitted.

The "neighborhood avoidance information acquisition unit" (0603)
It has a function of acquiring the surrounding avoidance information based on the vehicle operation information acquired by the vehicle operation information acquisition unit (0601) and the road occupant movement information acquired by the road occupant movement information acquisition unit (0602). The “surrounding avoidance information” is information for operating the vehicle so that the vehicle does not enter the predetermined range of the road occupant, and examples thereof include map information indicating such a route and voice information. Alternatively, speed information for operating the vehicle without entering a predetermined range may be cited.

FIG. 7 is a schematic diagram for explaining the peripheral avoidance information. As shown in this figure, the vehicle "●" (0701) to be route-guided is traveling in the direction of the arrow toward the destination. However, at this time, the ambulance "☆" (0702) is passing through the four corners in the figure toward the accident site. At this time, the route guidance device uses the planned route information and speed information of the vehicle, and the planned route information and speed information of the ambulance to predict the expected position information of the vehicle "●" and the ambulance "☆" at each predetermined time. To get. Then, it was determined that, if the vehicle "●" continued to run, the vehicle "●" would enter the prescribed range of the ambulance "☆" after 5 minutes. Therefore, this route guidance device uses the position information of the ambulance at each predetermined time and the destination information and speed information of the vehicle so that the vehicle "●" does not enter the predetermined range of the ambulance "☆". Find a route (arrow or arrow) to a new destination.

In this way, the driver of the vehicle can know the route that avoids the vicinity of the road occupant. Therefore, unlike the route that avoids the front, the driver of this vehicle is
For example, it is possible to avoid a route that is congested because other vehicles waiting until now behind the passing ambulance are moving at once.

Further, the acquisition of the information for the operation that does not enter the vicinity of the road occupant is more than that of the general vehicle as compared with the case of acquiring the information for the operation that avoids the front as in the first embodiment. Accurate simulation results such as ambulance planned route are not required. Therefore, it is possible to carry out with a simpler algorithm.

(Processing flow of the second embodiment)

FIG. 8 is a flow chart showing an example of the processing flow of the route guidance device of this embodiment. As shown in this figure, first, vehicle operation information is acquired (step S0801). Further, the road occupant movement information is acquired (step S0802). Finally, the step S
0801 and the vehicle operation information obtained in step S0
The surrounding avoidance information is acquired based on the road occupant movement information acquired in 802 (step S0803).

(Simple explanation of the effect of the second embodiment)

As described above, the route guidance device of the present embodiment can also obtain information such as the route and the speed at which the vehicle can travel without entering the predetermined range of the road occupant. . As a result, the driver can reach the destination without causing the vehicle to wait on the shoulder of the road, or without hitting a traffic jam caused by another vehicle that is waiting. In addition, since the road occupant does not have (general) vehicles around itself, smooth operation and implementation can be achieved.

In addition, the first embodiment for acquiring the front avoidance information
It is possible to carry out with a simpler algorithm as compared with.

<Third Embodiment>

(Concept of Embodiment 3)

Similar to the first embodiment, the present embodiment is a route guidance device for determining a detour route that avoids the forward direction of a road occupant and instructing the user to follow the detour route. However, the route guidance device of the present embodiment is basically not a device mounted on a vehicle but a server device of a service provider or the like. This is because the feature of the route guidance device of the present embodiment is that the route guidance vehicle is
This is because the detour route of the vehicle is presented so that it does not overlap with the detour routes of other vehicles. That is, in this embodiment, a large number of vehicles are used to avoid an ambulance or the like.
It is a route guidance device that selects, acquires, and transmits forward avoidance information for each vehicle so that the vehicle is not concentrated on one detour route and congestion or congestion does not occur.

(Structure of Embodiment 3)

FIG. 9 is a diagram showing an example of functional blocks of the route guidance device of the present embodiment. As shown in this figure, the “route guidance device” of this embodiment (0900)
Is a “road occupant movement information acquisition unit” (0901),
It has a "peripheral vehicle operation information acquisition unit" (0902), a "front avoidance information acquisition unit" (0903), and a "front avoidance information transmission unit" (0905), and is a "front avoidance information acquisition unit".
Further has "congestion avoidance selection means" (0904).

The description of the "road occupant movement information acquisition unit" and the "forward avoidance information acquisition unit" of the present embodiment is the same as that of the first embodiment, and will be omitted. The "peripheral vehicle operation information acquisition unit" has a function of acquiring vehicle operation information of vehicles operating around the road occupant. Therefore, the basic description is the same as that of the “vehicle operation information acquisition unit”, and the description thereof is omitted.

The "congestion avoidance selecting means" (0904) has a function of selecting, from among the front avoidance information, one in which the concentration of traffic by the vehicle is below a predetermined amount. In order to avoid the concentration of vehicles, "the concentration of traffic is less than or equal to a predetermined amount" may be, for example, that the number of vehicles passing through a unit road is less than or equal to a predetermined amount. When there is only one vehicle, the congestion avoidance selection means does not concentrate the vehicle regardless of which route is selected. Therefore, the front avoidance information acquired by the front avoidance information acquisition is directly (without selecting) the vehicle. May be sent to. In addition, if the peripheral vehicle operation information acquired by the peripheral vehicle operation information acquisition unit is the operation information of a plurality of vehicles, the front avoidance information that causes the concentration of traffic by the plurality of vehicles to be a predetermined amount or less is provided for each vehicle. May be selected.

A case where the congestion avoidance selecting means guides the route to a plurality of vehicles will be described with reference to a concrete example.
When one vehicle (four-wheeled vehicle) is guided to the route A, five minutes after the speed information of each vehicle, within a range of “the width of the road × 10 meters” which is a unit road on the route A,
It was determined that seven vehicles would pass. This road becomes congested when six or more four-wheeled vehicles concentrate on the unit road. Therefore, the forward avoidance information that guides another route to two of the seven vehicles is acquired so that the traffic concentration is less than or equal to the predetermined amount of five vehicles.

FIG. 10 is a schematic diagram for explaining the congestion avoidance selecting means. As shown in this figure, three vehicles “●” (1001, 1002, 1003, but all three are four-wheel vehicles) are traveling in the direction A.
At this time, the ambulance "☆" (1004) is traveling on the main street. These three vehicles (1001, 1002, 1003) that know the approach of the ambulance by some means request the route guidance device of this embodiment to search for a route avoiding the front of the ambulance. Therefore, in the route guidance device of the present embodiment, the front avoidance information acquisition unit first acquires the route information, which is the front avoidance information, for each vehicle. However, when the "congestion avoidance selecting means" guides these three vehicles to the route or to the route, it is determined that the concentration of traffic as described above becomes a predetermined amount or more. Therefore, as a route that does not cause this concentration of traffic,
Route to vehicle "●" (1001) and next vehicle "●"
The route to (1002), the last vehicle "●" (100
In 3), the route is acquired as forward avoidance information and transmitted to each vehicle. Alternatively, from the speed information of "●" (1003) and the ambulance "☆" (1004), "●" (100
If it is determined that 3) will not meet the ambulance "☆" even if it goes straight ahead, the route guidance device acquires route information indicating that it will go straight and sends it to "●" (1003). May be.

In this way, it is possible to obtain information such as the route for each vehicle so that the vehicles are not concentrated in one place.

The route guidance device of this embodiment will be described again with reference to FIG.

The "forward avoidance information transmitter" (0905) is
The front avoidance information acquired by the front avoidance information acquisition unit (0903) is transmitted to the vehicle. Of course, the forward avoidance information finally acquired by the forward avoidance information acquisition unit is the forward avoidance information selected by the congestion avoidance selecting means (0904). Then, if the route avoidance information is used for route guidance to a plurality of vehicles, the vehicles are specified based on, for example, vehicle identification information, and the internet network or wireless communication network is used for each vehicle. And send it.

Since each vehicle is guided to a different route by the forward avoidance information thus transmitted, it is possible to avoid the forward direction of the road occupant without concentration of traffic.

(Processing flow of the third embodiment)

FIG. 11 is a flowchart showing an example of the processing flow of the route guidance device of this embodiment.
As shown in this figure, first, road occupant movement information is acquired (step S1101). In addition, peripheral vehicle operation information is acquired (step S1102). Subsequently, forward avoidance information is acquired based on the road occupant movement information acquired in step S1101 and the surrounding vehicle operation information acquired in step S1102 (step S110).
3). Further, the front avoidance information acquired in step S1103 is selected so that the concentration of traffic by the vehicle is a predetermined amount or less (step S1104). Finally, the front avoidance information selected in step S1104 is transmitted to the vehicle (step S1105).

(Simple explanation of the effect of the third embodiment)

As described above, the route guiding device of the present embodiment makes it possible to prevent the vehicle from traveling ahead of the road occupant without causing concentration of traffic such as congestion.

As described in the above concept, the description of the “road occupant movement information acquisition unit” and the “surrounding avoidance information acquisition unit” of this embodiment is the same as that of the second embodiment. The description of the “vehicle operation information acquisition unit” is the same as that of the third embodiment, and the description thereof is omitted.

Then, "congestion avoidance selection means" (120
In 4), the surrounding avoidance information is selected so that the traffic of the vehicle is not concentrated in the same manner as described in the third embodiment. Finally, in the "surrounding avoidance information transmitting unit" (1205), as in the case of the forward avoidance information transmitting unit of the third embodiment, the surrounding avoidance information selected by the congestion avoidance selecting unit (1204) of the surrounding avoidance information acquiring unit. To the vehicle.

In this way, the vicinity of the road occupant can be avoided without causing the concentration of traffic by a plurality of vehicles.

(Processing flow of the fourth embodiment)

FIG. 13 is a flow chart showing an example of the processing flow of the route guidance device of this embodiment.
As shown in this figure, first, road occupant movement information is acquired (step S1301). In addition, peripheral vehicle operation information is acquired (step S1302).
