Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guidance device for displaying a current position and a route to a destination, and more particularly to a guidance device suitable for wheelchairs and the like, and a wheelchair equipped with the guidance device.

[0002]

2. Description of the Related Art A movement support means such as a wheelchair or a three-wheeled cart for an elderly person or a physically handicapped person to board and move is affected by various factors such as steps, unevenness, inclination, presence of obstacles, traffic volume, etc. As a result, the routes that can be traveled are limited compared to general pedestrians. For this reason, a wheelchair, a three-wheeled cart, or the like may encounter a route that cannot be traveled or is difficult to travel before reaching the destination. In such cases,
Since it is necessary to find a new route to reach the destination, it has been proposed to provide a guiding device in a wheelchair, a three-wheel cart or the like.

The guide device displays the current position and the route to the destination so that the user does not get lost to the destination. The user travels while referring to the current position displayed on the guidance device and the route to the destination, that is, the planned travel route. When the user discovers a factor that obstructs travel such as an obstacle while traveling on the planned traveling route and determines that the route cannot be traveled, or when it is determined that it is better to bypass the route, the user Searches for a new route with the guidance device. As a result, the user travels on a travelable route by referring to the new scheduled travel route searched by the guidance device again.

As a guide device suitable for a wheelchair, a three-wheel cart, etc., there is one provided with a failure detection device as proposed in, for example, Japanese Patent Laid-Open No. 11-290390. When an obstacle detection device detects an obstacle on the route that prevents a wheelchair, a three-wheeled cart, or the like from traveling, the guidance device equipped with such an obstacle detection device re-searches the route to the destination, and creates another route. To select. As a result, the wheelchair and the three-wheel cart can travel on the newly selected travelable route.

[0005]

However, it is difficult for a user of a wheelchair or a three-wheel cart to recognize an obstacle such as a wheelchair or a three-wheel cart, that is, a factor that hinders the traveling of the wheelchair or the three-wheel cart. For example, it is difficult to determine what level of step or inclination will hinder the running of the wheelchair, and what kind of obstacle will hinder the running of the wheelchair. Further, factors that hinder the running of a wheelchair, a three-wheel cart, etc. differ depending on the function of the wheelchair, the three-wheel cart, etc., and the degree of the user's disability, and so on.
It is difficult for the obstacle detection means of the guidance device as proposed in Japanese Patent Publication No. 90 etc. to detect a factor that hinders traveling. In this way, if the user misrecognizes or cannot detect the factors that hinder driving, the wheelchair or the three-wheeled cart cannot climb the step that it thinks it can get over or the slope that it thinks it can go up. Depending on the case, it may get stuck. Therefore, there is a demand for a guidance device that can select a route that does not hinder traveling as much as possible as a planned traveling route.

An object of the present invention is to provide a guidance device capable of selecting a route that does not interfere with traveling as much as possible as a planned traveling route.

[0007]

The present invention solves the above problems by the following means. That is, the guiding device of the present invention is
A guidance device for displaying the route from the detected current position of the user to the input destination and the current position of the user, wherein a route used in the past is stored as a travel record route, Among the stored actual travel routes, the actual travel route corresponding to the current position of the user and the destination is displayed.

Further, in the guidance device of the present invention, one of a plurality of routes from the detected current position of the user to the input destination is set as the planned traveling route, and the planned traveling route and the use are used. Of the traveling history storage means for storing the route used in the past as the traveling history route and the traveling history route stored in the traveling history storage means. It is configured to include a selection unit that selects at least a part of the actual travel route displayed corresponding to the current position of the user and the destination as at least a part of the planned travel route.

In this way, the route used in the past is displayed as the actual traveling route, so that the user of the guidance device can confirm the actual route used in the past when setting the planned traveling route as the route to the destination. At least a part of a certain travel record route can be selected. Since the actual traveling route has a history of traveling in the past, it is less likely that the route has a factor that hinders traveling as compared with a route that has never traveled.
Therefore, the guiding device of the present invention has fewer factors that hinder traveling as compared with a case where the planned traveling route is configured only by a route that has not been traveled by configuring at least a part of the planned traveling route with the traveling actual route. The route can be selected as the planned traveling route.

[0010] Further, there is provided storage means for storing the number of times of use of the travel record route, and the display mode of the travel record route is changed and displayed according to the number of times of use of the travel record route stored in the storage means. It will be configured.

Further, it has a storage means for storing the use time of the travel record route, and the display mode of the travel record route is changed and displayed in accordance with the use time of the travel record route stored in the storage means. It will be configured.

As described above, by changing the display form of the actual travel route that has been used in the past according to the number of times and the time when the actual travel route is used, the user can use the actual travel route. It is possible to recognize the frequency and the time of use, and when setting the planned traveling route to the destination, it is possible to select a traveling record route that is frequently used or a recently used traveling record route. Therefore, the guidance device of the present invention can select a route having fewer factors that hinder the traveling as the planned traveling route, as compared with the case where the planned traveling route is configured only by a route that has never traveled.

Further, the wheelchair of the present invention comprises any one of the above guiding devices.

As described above, the wheelchair user is prevented from traveling by providing the guiding device for storing the route used in the past as the actual traveling route and using it for selecting the planned traveling route. It is possible to select at least a part of the actual travel route that is unlikely to have the factor as at least a part of the planned travel route.

An electric wheelchair according to the present invention comprises any one of the above guiding devices, a driving unit for driving wheels, and a control unit for controlling the driving unit, wherein the guiding device is the current user's vehicle. The position is collated with the displayed planned traveling route, and the control unit controls the drive unit based on the collation result of the guidance device.

As described above, the electric wheelchair is provided with a guide device capable of selecting at least a part of the actual travel route that is unlikely to have a factor that hinders the travel as the planned travel route, and the guidance device is collated. By controlling the electric wheelchair based on the results, the electric wheelchair travels on a planned route that is easy to drive, safe and convenient with low possibility of difficult or impossible routes. can do.

A collation unit 6 that collates the detected current position at any time, a route that the wheelchair has used in the past, that is, a route history storage unit 8 that stores the actual travel route that the wheelchair has traveled, and a map that stores map information. The information storage unit 9 and the like are included.

The guiding device 1a thus constructed can be mounted on the wheelchair body 10 as shown in FIG. In this case, the interface 2 of the guiding device 1a can be attached to the operation unit 11 of the wheelchair body 10, for example. The wheelchair body 10 is a chair equipped with wheels 12 that is devised for people with disabilities, such as the elderly and the physically handicapped. Used for moving.

The interface 2 of the guiding device 1a attached to the operating portion 11 of the wheelchair body 10 is, for example, as shown in FIG.
As shown in FIG. 3, the input unit 3 for inputting the destination and the route to the destination, the display unit 4 composed of a touch panel, and the speaker 14 used when performing guidance by voice are provided. Input unit 3 of interface 2 of guidance device 1a
Is composed of a touch pen 3a for operating a touch panel which is the display unit 4 to input a destination and a route to the destination, an operation switch 3b for scrolling and switching the screen of the display unit 4, and the like.

The operation of the guiding device 1a having such a structure and the characteristic part of the present invention will be described. The user uses the guidance device 1
The destination is input using the input unit 3 such as the touch pen 3a and the operation switch 3b provided in the interface 2 of a. The input destination is the position detection unit 7 such as GPS.
The map information displayed on the display unit 4 is displayed together with the current position detected by. After inputting the destination, the user selects a route from the current position to the destination and inputs it as the planned traveling route. The input destination and planned travel route are stored in the route storage unit 5. The stored planned traveling route and the current position detected by the position detection unit 7 are collated by the collation unit 6 at any time, and the collation result is displayed on the display unit 4 of the interface 2.

The user runs the wheelchair toward the destination along the input planned traveling route while referring to the map information and the collation result displayed on the display unit 4. The route traveled by the wheelchair is stored in the route history storage unit 8 that stores the current position detected by the position detection unit 7 as a route that has been used in the past, that is, a travel record route that has been traveled. . The route history storage unit 8 always stores the current position of the wheelchair detected by the position detection unit 7 in correspondence with the map information stored in the map information storage unit 9, and accumulates it as a wheelchair traveling history. The travel record route accumulated as the travel history in the route history storage unit 8 is saved even after the use of the guidance device 1 is finished. The stored travel record route can be displayed by being superimposed on the map information displayed on the display unit 4 and used when the planned travel route is selected by the guidance device 1a.

As shown in FIG. 4, the display unit 4 of the guidance device 1a, which has traveled many times along the route and accumulated the travel history, displays the map information 15 stored in the map information storage unit 9 and the touch pen 3 as shown in FIG.
It is possible to display the destination 21, the current position 23 detected by the position detection unit 7 such as GPS, and the actual travel route 25 stored in the route history storage unit 8 input by a. The black circles in FIG. 4 indicate the destinations 21 previously input by the touch pen 3a, and the white circles indicate the position detection unit 7.
The current position 23 of the user detected by the broken line is shown, and the broken line shows the travel record route 25 corresponding to the destination 21 and the current position 23 among the routes in which the wheelchair has traveled in the past. The solid line indicates that the wheelchair has never traveled in the past, that is, the route 30 that has no travel record.

In this way, on the display unit 4 of the guide device 1a displaying the actual travel route 25 where the wheelchair has traveled in the past, the user can, for example, select a section from one corner of the road to another on the map. By designating a part of this line segment as one line segment with the touch pen 3a or the like, the planned travel route to the destination 21 can be set and input. At this time, since the actual travel route 25 that has been used in the past is displayed on the map, the user can easily identify and select the actual travel route 25. That is, when inputting the planned travel route from the current position 23 to the destination 21, the current position 23 to the current position 23 on the map of the display unit 4 are input.
The actual travel route 25a to the next corner above is selected as the first section of the planned travel route, and similarly, the actual travel route 2 is selected.
By selecting the actual travel route 25k from 5b as the second to eleventh intervals of the planned travel route, avoiding the routes 30a and 30b having no actual travel, the planned travel route from the current position 23 to the destination 21. You can select and enter.

Since the selected actual traveling route 25a to the actual traveling route 25k are a part of the routes that have been used in the past, it is confirmed that each section of the previous traveling route can be traveled. Has been done. For this reason, it is less likely that the planned traveling route from the current position 23 to the destination 21 includes a route in which the wheelchair is difficult to drive or a route in which the wheelchair is incapable of traveling.

Thus, the guiding device 1a of this embodiment
The route history storage unit 8 always stores the current position 23 of the wheelchair detected by the position detection unit 7, and
5 can be accumulated as the traveling history of the wheelchair, and the accumulated traveling result route 25 can be displayed on the display unit 4 together with the map information 15. Therefore, when setting the planned travel route from the current position 23 to the destination 21 with the guidance device 1a according to the present embodiment, the user can easily identify the travel record route 25 that has been used in the past. You can Therefore, the user of the guidance device 1a of the present embodiment can select a part of the actual travel route that is unlikely to have a factor that hinders the travel as the scheduled travel route.

By the way, the guiding device 1a of this embodiment is
As shown in FIG. 5, when the current position 23 of the wheelchair deviates from the planned traveling route 22, an arrow 24 is displayed on the display unit 4. The arrow 24 indicates the current position 23 detected by the position detector 7.
Is a comparison result obtained by comparing the stored planned travel route 22 with the stored travel route 22 and indicates the direction in which the user should travel. in this case,
An arrow 24 indicating the direction in which the user should go is directed from the detected current position 23 to the planned travel route 22.

However, the planned traveling route 22 with a proven track record
In c, for example, when a new factor that makes it difficult for a wheelchair to run, such as road construction or a parked vehicle, the wheelchair has to run off the preset planned route 22. In this case, the user of the guiding device 1a needs to newly search for a route to the destination. JP 2000
The conventional guidance device as described in Japanese Unexamined Patent Publication No. -20874 does not take into consideration the point that the user changes the route to the destination while moving. It is necessary to re-enter the destination and the route to the destination.

Further, the guidance device as proposed in Japanese Patent Laid-Open No. 11-290390 or the like automatically re-searches for another new route at the time when the obstacle for running the wheelchair is detected. There is. However, Japanese Patent Laid-Open No. 11-2903
The guidance device as proposed in Japanese Patent Publication No. 90 does not consider whether or not the wheelchair can travel along the route when searching for the route. In other words, it is not taken into consideration whether or not the searched route is the factor that impedes the wheelchair running, and the newly searched route includes a route where the wheelchair is difficult or impossible to drive. There is.

As described above, since the conventional guiding device does not consider whether or not the searched route is a factor that impedes the running of the wheelchair, it is necessary to re-search the route each time there is a failure. It is inconvenient for people traveling in. For this reason, by displaying a travel route that has as few obstacles as possible, it is possible to provide a highly convenient guidance device that does not require repeated search of the travel route and does not need to change the travel route many times. Is desired.

On the other hand, the guiding device 1a of the present embodiment
Is, for example, the travel record routes 25l and 25 used in the past.
Since m, 25n and 25o are displayed on the display unit 4,
These running performance routes are 25l, 25m, 25n, 25o
By selecting, the user can set and input a new planned traveling route 26 as shown in FIG. The newly input planned travel route 26 is stored in the route storage unit 5. When the new planned travel route 26 is input, the guidance device 1a re-matches the current position 23 with the new planned travel route 26 by the verification unit 6, and the result of the verification is indicated by the arrow 2
7 is displayed.

As described above, the user selects the travel record routes 25l, 25m, 25n, 25o having the record of travel from the plurality of routes even during the movement to the destination 21, It is possible to input a new planned traveling route 26. Therefore, even when the guidance device 1a changes the planned travel route during the movement to the destination 21,
It is possible to easily change the planned travel route by selecting a previously traveled travel route that has been used in the past and is unlikely to have a factor that hinders travel.

In addition, the actual traveling route 25 used in the past
Since 1, 25m, 25n, and 25o are unlikely to have a factor that hinders traveling, there is a high possibility that the newly set planned traveling route has no factor that hinders traveling. For this reason,
Even if the planned travel route is changed in the middle, the changed planned travel route will not be able to travel more often, and the need to search the planned travel route again and again is reduced, thus improving the convenience of the guidance device. You can

(Second Embodiment) A second embodiment of the guiding device to which the present invention is applied will be described with reference to FIGS. 7 and 8. FIG. 7 is a block diagram showing a schematic configuration of the guidance device according to the second embodiment to which the present invention is applied. FIG. 8 shows a second guiding device to which the present invention is applied.
6 is a diagram showing a display example of a display unit of the interface in the embodiment of FIG. In the present embodiment, the same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.
The configuration, the characteristic part, and the like different from the embodiment will be described.

The present embodiment is different from the first embodiment in that the route record storage unit 8 has used the previously used travel route 2
5 is stored, and a travel count storage unit 28 that stores the number of travels along the route is provided, and the display mode of the travel history on the display unit 4 is changed stepwise according to the number of travels along the route. .

The display unit 4 of the guiding device 1b of this embodiment is
For example, as shown in FIG. 8, the track record route 31 that has traveled 10 times or more in the order of thick broken lines, and 5 times or more 10 times
A travel record route 32 that has been traveled less than once and a travel record route 33 that has been traveled once or more and less than 5 times are displayed.

In this way, by displaying the broken line thicker for a route with a larger number of times of travel, it is possible to easily identify the number of times of travel of that route, and the actual results of travel when selecting a planned route. It is possible to select a route having a large number of travels from among the routes having the above. Therefore, it is possible to further reduce the possibility that the planned traveling route 22 from the current position 23 to the destination 21 includes a route in which the wheelchair is difficult to drive or a route in which the wheelchair is incapable of traveling.

Furthermore, the user selects a traveling actual route 31 having a high traveling frequency from a plurality of routes to set a new scheduled traveling route even during the movement to the destination 21. be able to. Therefore, the guidance device 1b newly creates the travel record route 31 with a high frequency of use, which is less likely to have a factor that hinders the travel, even when the planned travel route is changed during the movement to the destination 21. It is possible to easily change the planned travel route by selecting it as a planned travel route.

(Third Embodiment) A third embodiment of the guiding device to which the present invention is applied will be described with reference to FIG. FIG. 9 is a block diagram showing a schematic configuration of the guidance device according to the third embodiment to which the present invention is applied. In addition, in this embodiment, the same components as those in the second embodiment will be denoted by the same reference numerals and the description thereof will be omitted, and a configuration, a characteristic portion, and the like different from those in the second embodiment will be described.

The present embodiment is different from the second embodiment in that the route history storage unit 8 stores a route 25 used in the past and a travel time storage unit 29 that stores the time when the route was traveled. The display mode of the traveling history on the display unit 4 is changed stepwise according to the traveling time. Similar to the display unit 4 of the second embodiment, the display unit 4 of the guidance device 1c of the present embodiment, for example, in the order of thick broken lines, is a route in which the time elapsed after the last run is within one week,
Displays the route that has passed since the last run for more than one week and less than one month, and the route that has passed since the last run for more than one month and less than half a year.

In this way, by displaying the broken line thicker for a route that has been traveled more recently, it is possible to easily identify the time when the route has been traveled, and when selecting a planned traveling route,
The route that has recently traveled can be selected from the routes with a track record of traveling. Therefore, from the current position 23 to the destination 2
It is possible to further reduce the possibility that the route up to 1 includes a route in which the wheelchair is difficult to drive or a route in which the wheelchair is incapable of traveling.

Further, even if the user is on the way to the destination 21, the user can select the latest traveled route from a plurality of routes and set a new scheduled route. it can. Therefore, the guidance device 1c determines that the destination 2
Even if the planned travel route is changed in the middle of the movement to 1, the travel record route that has been used recently, which is less likely to cause the obstacle to travel, is selected as the new planned travel route, and the travel is facilitated. You can change the planned route.

An embodiment of the electric wheelchair to which the present invention is applied will be described with reference to FIG. Figure 1
FIG. 0 is a block diagram showing a schematic configuration of an embodiment of an electric wheelchair to which the present invention is applied.

Has been done.

The collation unit 6 of the guiding device 1a collates the planned travel route that has been input and stored in advance with the current position detected by the position detection unit 7 as needed, and the result is interface 2
Is displayed on the display unit 4, which is a part of the above, and the verification result is transmitted to the electric wheelchair control unit 36. Electric wheelchair controller 3
6 calculates the traveling direction of the electric wheelchair main body 34 based on the verification result from the verification unit 6, converts it into the rotational speed of the wheels, and transmits it to the electric wheelchair drive unit 35. The electric wheelchair drive unit 35, based on a command from the electric wheelchair control unit 36,
The wheels of the electric wheelchair body 34 are driven. When changing the route on the way to the destination, the user operates the electric wheelchair main body 34 to drive a route different from the route input in advance, or ends the automatic traveling using the interface 2. At this time, the display unit 4 displays a travel record route with a record of past travels. The user selects and inputs a new planned travel route from the displayed actual travel routes.
The user uses the interface 2 of the guidance device 1a to
An instruction is given to restart the automatic running of the electric wheelchair body 34.

As described above, the electric wheelchair of this embodiment is
The route to the destination can be selected from the actual traveling routes having the actual traveling records, and the planned traveling route can be autonomously traveled. Also, when the user wants to change the input planned traveling route while autonomously traveling to the destination with the electric wheelchair, the user can display the traveling actual route with the actual traveling record and select the route with the actual traveling record. .

Further, although the position detecting section 7 of the guiding devices 1a, 1b, 1c of the first to third embodiments is composed of GPS, the position detecting unit of the guiding device of the present invention is GP.
The present invention is not limited to S, and various configurations such as recognizing the current position by detecting a point marker installed on the road can be adopted.

The guide devices 1a, 1b, 1c of the first to third embodiments are provided in a wheelchair or an electric wheelchair, but the guide device of the present invention is applied to a walking assist vehicle. Can also achieve the same effect. Here, the wheelchair is a chair equipped with a car, which is devised for a person with a disability, and the electric wheelchair has a driving means such as an electric motor among the wheelchairs. The electric wheelchair having the driving means includes, for example, a three-wheel cart. In addition, the walking assist vehicle includes a baby carriage for carrying infants and the like, and a wheelbarrow used by elderly people who have difficulty walking.

Although selection and setting are explained, when setting the planned traveling route, depending on the destination and the current position,
In some cases, the actual travel route does not exist continuously from the current position to the destination. For example, in the case where the destination is the first place to visit, it is unlikely that the actual travel route exists continuously from the current position to the destination. In such a case, the guidance device of the present invention can set the planned travel route including a route that has no travel record. In this case, the user of the guidance device of the present invention selects the planned traveling route so that the section with no traveling record is as small as possible. As a result, the number of routes that have not been traveled is reduced in the planned traveling route, and the possibility that a route in which the wheelchair is difficult to travel or a route in which the wheelchair cannot travel is included can be reduced.

Further, in the guiding devices 1a, 1b, 1c of the first to third embodiments, the user selects and instructs a route, but the guiding device of the present invention routes the route to the destination. You can search automatically. When automatically searching for a route, for example, by selecting a travel record route having a travel record from the travel history accumulated in the route history storage unit, the travel record route is included in at least a part of the searched planned travel route. Therefore, it is possible to reduce the possibility that the planned traveling route set by the automatic search includes a route in which the wheelchair is difficult to drive or a route in which the wheelchair cannot travel. Furthermore, the guidance device of the present invention automatically searches for a route to a destination based on the number of times of travel and the time of travel recorded in the number-of-runs storage unit and the time-of-run storage unit. It is possible to further reduce the possibility that the planned route includes a route in which the wheelchair is difficult to travel or a route in which the wheelchair cannot travel.

Further, in the guidance devices 1a, 1b, 1c of the first to third embodiments, the destination 21 and the current position 23.
The black circles and the white circles are respectively displayed, but various other shapes and colors can be displayed. For example, if the display of the current position is a triangle, the traveling direction of the wheelchair on the map can be identified. When the traveling direction of the wheelchair is displayed, the traveling direction of the wheelchair can be recognized and displayed on the display unit based on the deviation between the current position recognized by GPS or the like and the past position stored in the route history storage unit or the like. .

Further, the guidance devices 1a, 1b, 1c of the first to third embodiments have the operation switch 3b as an input means in the interface 2, but the operation switch of the guidance device of the present invention is a touch panel. It can be configured to be displayed inside and operated by a touch pen.

In addition, the first to third guidance devices 1a, 1
In b and 1c, the collation result is displayed on the display unit 4 by the arrows 24 and 27, but the collation result of the collation unit of the guiding device of the present invention is configured to indicate the direction by using a voice with a speaker. You can

The guiding device 1a according to the first to third embodiments,
The display unit 4 of 1b, 1c can also travel with the actual travel route displayed, or after selecting the planned travel route, the actual travel route is hidden and the actual travel route is not displayed. You can also In addition, when traveling without displaying the actual travel route, when the actual travel route needs to be displayed, for example, when the new planned travel route is deviated from the input planned travel route, it is automatically performed. It is possible to display the travel record history.

The guiding device 1b of the second and third embodiments,
In the display mode of the actual traveling route of 1c, the thickness of the broken line is changed stepwise according to the number of traveling times and the traveling time. Can be recognized, various display modes such as changing the color of the route stepwise or changing the line type of the route stepwise can be adopted.

Furthermore, the display mode of the actual travel route of the guidance device of the present invention is switched between display and non-display according to the number of travels and the traveling time, and the number of travels and the traveling time of each actual travel route are identified. be able to. When changing the display mode according to the number of times of travel, for example, the actual number of times of travel is once or twice,
When the display switch of the actual traveling route is pressed once in three stages from 3 times to 5 times and 6 times or more, a broken line indicating the traveling actual route where the number of times of traveling is 6 times or more is displayed, and then it is pressed once more. In addition to the broken line indicating the route where the number of times of travel is 6 times or more, the broken line indicating the actual travel route where the number of times of travel is 3 to 5 times is displayed. In addition to the broken line indicating the actual traveling route and the broken line indicating the actual traveling route where the number of times of traveling is 3 to 5, it is possible to display a broken line indicating the actual traveling route where the number of times of traveling is 1 to 2. Also, when the display mode is changed according to the traveling time, as in the case where the display mode is changed according to the number of times of traveling, for example, there are three stages, that is, when the traveling time is within one week, within one month, and over one month. The display can be switched according to the number of times the display switch of the travel record route is pressed.

In this way, when the display and non-display of the traveling result route are switched according to the number of times of traveling and the traveling time of the traveling result route, the accumulated traveling result route increases and the display is difficult to see. Moreover, only the necessary information can be displayed on the display unit.

According to the present invention, it is possible to provide a guidance device capable of selecting a route that does not interfere with traveling as much as possible as a planned traveling route.
