Abstract

PROBLEM TO BE SOLVED: To make a search along a route, which is effective for reducing the time of stay.SOLUTION: A navigation device sets a first search region 63 in a range of a first distance from a driving route 62 and a second search region 64 in a range of a second distance larger than the first distance, along the driving route 62 from a current position 61. The navigation device makes a search within the first search region 63 with respect to facilities without drive through services (DTS) and makes a search within the second search region 64 with respect to facilities with DTS. Results of these searches are integrated and presented to a user. Therefore, the user can make a search for even facilities with DTS somewhat distant from the driving route 62. Though it takes some time to stop at a facility with DTS somewhat distant from the driving route 62, the time required for his or her entire trip can be considerably reduced because of a short time of stay there.SELECTED DRAWING: Figure 2

Description

  The present invention relates to a navigation device, for example, a search for facilities existing along a travel route.

Driving assistance using navigation devices is widely performed.
The navigation device searches and sets the travel route to the destination and provides guidance such as "I'm about to turn right soon" to reduce the user's driving load and provides various services such as a search function along the route. ing.
This search along the route searches for various facilities that may stop along the route you searched for, such as restaurants, convenience stores, gas stations, parking lots, and the location and distance of those facilities. It is a function that displays information on the screen and provides it, and is also called search along the route.

By the way, some facilities that are subject to a search along a route provide a so-called drive-through service that allows a user to receive a service while riding.
Therefore, in the technology described in Patent Document 1, the presence / absence information of the drive-through service is stored, and when the result of the search along the route is displayed on the screen, whether the facility is provided or not is clearly indicated. It makes it possible to shorten the stay time.

In the search along the route, the facility existing within a certain distance (for example, 500 m) from the travel route including the technique described in Patent Document 1 is a search target. For this reason, even if it is a facility that provides a drive-through service, it is not searched if it exists outside the search range.
However, facilities that provide drive-through services are required to stop by even if they are located slightly outside the search range compared to using facilities that do not provide the service within the search range. In some cases.

(1) Outline of Embodiment As shown in FIG. 2, the navigation device has a first distance (for example, 50 m) in the direction perpendicular to the travel route 62 along the travel route 62 from the current position 61 of the vehicle. The first search area 63 is set, and a second distance area (for example, 100 m) larger than the first distance is set in the second search area 64.
The navigation device performs a search along a route in the second search area 64 for a facility where information indicating that a drive-through service (hereinafter referred to as DTS) is provided (hereinafter referred to as a facility with DTS). .
On the other hand, a route in the first search area 63 for a facility that does not have information indicating that a DTS is provided (a facility that does not provide a DTS and a facility that is not provided. Search along.
The navigation device integrates both search results and provides them to the user together with the presence or absence of DTS.

In this way, by changing the facility search range depending on the presence or absence of DTS, it is also possible to search for a facility with DTS that is located a little away from the travel route 62.
The facility with DTS that is a little away from the travel route 62 requires a little time to stop, but because the stay time is short, the stay time required for the entire process can be shortened, and more information on the presence or absence of DTS can be obtained. It can be used effectively.

  By setting the second distance on the opposite lane side to be shorter than the second distance on the traveling lane side, it is possible to avoid an increase in the staying time when using the facility as a result.

The road map is composed of roads such as main trunk roads, expressways, narrow streets, and ground targets (facility, etc.). The house map is a city map on which a figure representing an outer shape of a ground building, a road name, and the like are displayed. The narrow street is, for example, a relatively narrow road having a road width equal to or less than a predetermined value below a national road or prefectural road.

As for the map data, a map of a predetermined range including a current vehicle position and a point designated by the user is displayed on the display 42 at a predetermined scale. On this map, the current position of the vehicle and the designated point are displayed.
The road data is data relating to roads such as the position and type of each road, the number of lanes, and the connection relationship between the roads, and is composed of node information and link information. The road data is used for route search and map matching, and is also used when the searched travel route is displayed over the map data.

The facility information file 52 stores facility information related to facilities providing various services.
The facility information is information for searching according to a request from the user and presenting it as a guidance target. For each facility, for example, business type (retail store, government office, hospital, etc.), business type (if a retail store, a restaurant) , Convenience store, department store, etc.), name, location information of location, telephone number, presence / absence of DTS provision, etc. Whether or not DTS is provided is set by flag information, for example.
These facilities are called POI (Point of Interest) and are searched by the user.
Of the facility information, the position information is used to determine whether the facility is in the search area, and the business type and name are used to search the business type and name, respectively.

Examples of facilities that provide DTS include restaurants (including fast food restaurants), pharmacies, banks, and coffee shops.
In addition, since the clerk at the gas station where the clerk refuels performs the refueling while the user gets on, the stay time can be expected to be shortened compared to the self-service gas station. Therefore, in this embodiment, a refueling service performed by a store clerk at a gas station may be included in the DTS (Drive Through Service). In this case, the gas station where the clerk refuels is the facility with DTS, and the self-service gas station where the user himself refuels is the facility without DTS.

  The navigation device 1 configured in this manner sets a search area along a travel route when a search term such as “restaurant” is selected by a user after that, and a search region is set along the travel route. Among the facilities to be searched, those corresponding to the search word are searched based on the facility information file 52 and displayed on the display 42.

  As will be described later, the navigation apparatus 1 sets a threshold value that defines the search area for the facility with DTS larger than the threshold value for the search area for the facility without DTS (that is, the former search area is wider than the latter search area). For a facility with DTS, the effect of shortening the stay time can be expected even if it is slightly away from the travel route, so this is displayed as a search target facility.

Hereinafter, search along a route in the present embodiment will be described.
FIG. 2A is a diagram for explaining a range in which the navigation device 1 performs a search along a route.
In the map 60, the CPU 21 develops a map defined by map data, the current position of the vehicle, the vehicle travel route, and facilities based on the facility information on the RAM 24 and logically expands it in a virtual space on the data. It is the figure which represented what was formed typically visible.
Each rectangle shown in the figure represents a block (block), and an interval between the blocks represents a roadway.
It is assumed that the vehicle is present at the current position 61 represented by a triangle and a circle indicating the traveling direction, and is traveling in the direction of the arrow indicated by the traveling route 62 on the traveling route 62 obtained by the route search.

The current position 61 is a position specified by the CPU 21 based on the detection value from the current position detection device 10.
The travel route 62 is calculated by the CPU 21 using the information in the map data file 51 from the predetermined departure point to the destination input by the input device 41, and stored in the RAM 24. It is what. However, as described above, the travel route to the destination searched by the navigation server or the personal computer may be acquired from the communication interface 25 and stored in the RAM 24. Here, the predetermined departure point corresponds to the current position of the vehicle at the time of route search or the departure point input by the user.
Thus, the navigation device 1 includes route acquisition means for acquiring a travel route to the destination.

In the block defined by the map data, various facilities defined by the location information of the facility information in the facility information file 52 are distributed at the locations.
In FIG. 2, as an example, the search target facility designated by the user is a restaurant, and the facility symbol indicating the restaurant is shown. In FIG. 2, the display of facilities such as gas stations and banks that are not classified as search targets is omitted.
A facility with DTS is indicated by attaching a “D” symbol to the facility symbol, and a facility without DTS is not attached with a “D” symbol. The navigation device 1 determines the presence / absence of the DTS based on the flag information set in the facility information.
Thus, the navigation apparatus 1 includes facility information acquisition means for acquiring facility information including the presence or absence of DTS.

When the user designates a search along the route from the input device 41 and selects a search word such as “restaurant” at the current position 61 of the vehicle shown in the map 60, the navigation device 1 searches along the route as described later. To search for target facilities along the route.
Thus, the navigation apparatus 1 includes a search request acquisition unit that acquires a facility search request (search word).

When the search along the route and the selection of the search word are performed, the navigation device 1 searches the facility without DTS in the same range as the first search area 63 as before, and wider for the facility with DTS. The search is performed within the range of the second search area 64.
Here, as shown in FIG. 2 (a), the first search area 63 has a first distance (for example, 50 m on one side) in a direction away from the current travel route 62 and a predetermined distance in the traveling direction (for example, 50 m on one side). 5 km).
The second search area 64 is a range surrounded by a predetermined distance (for example, 5 km) in the traveling direction at a second distance (for example, 100 m on one side) having a large first distance.
The predetermined distance in the traveling direction is the same distance in both the first search area 63 and the second search area 64, but different distances may be set.
Further, the predetermined distance in the traveling direction with respect to the first search area 63 and the second search area 64 is not set to a constant value, and the DTS-free facility within the first distance from the current position 61 of the vehicle along the travel route 62 and the second distance The facilities with DTS within may be searched, and the search may be terminated when the total of both reaches a predetermined number N. In this case, the distance to the point where the number of search objects is the predetermined number N is the predetermined distance in the traveling direction. The predetermined number N is set to N = n × m = 50 in consideration of the list display number n (for example, 10) and the scroll count m (for example, 5 times) when displaying the search result.

As a result of the search along the route in this way, each facility (facility classified as a search word) surrounded by a dotted line in FIG. 2A is searched.
That is, from the first search area 63 (= the overlapping area of the second search areas 64), the facilities having no DTS 70b and 70d and the facilities having a DTS 70a and 70c are searched. This search result is the same as when a certain distance defining the search range is 500 m in the conventional search along the route.
In contrast, in the present embodiment, the DTS-equipped facilities 72b and 72e are further retrieved from the second search area 64 that does not overlap with the first search area 63 (hereinafter referred to as the third search area), and the DTS-free facilities. The facilities 72a, 72c, 72d, and 72f that are are not searched.

When the navigation device 1 performs the search along the route in this way, the search result (information of the searched facility) is stored in the RAM 24 and displayed on the display 42 together with the presence / absence of DTS provision.
As described above, the navigation device 1 includes a presentation unit that presents the facility searched by the facility search unit together with the presence or absence of the DTS.

In addition, since the 1st search area | region 63 and the 2nd search area | region 64 overlap, it is necessary to avoid the duplication search of a facility. Therefore, when performing a search along a route with the selected search word, duplication is avoided by one of the following methods.
(A) First method The first search area 63 is set to perform a search limited to facilities without DTS (search by a search term; the same applies hereinafter), and the second search area 64 is set to limit to facilities with a DTS. Search and integrate both search results.
In this case, the navigation device 1 sets an area setting for setting a first search area at a first distance from the travel path and a second search area at a second distance greater than the first distance from the travel path along the travel path. The facility search unit searches for a facility in the first search region with a facility having no DTS as a search target, and searches for a facility in the second search region with a facility having the DTS as a search target.

(B) Second method The first search area 63 is set to perform a search for all facilities regardless of the presence or absence of the DTS, and the third search area (the first search area of the second search areas 64) And a search that is limited to the facility with DTS is performed, and both search results are integrated.
In this case, the navigation device 1 sets the first search area 63 at the first distance from the travel route along the travel route and the third search area at the second distance outside the first search region 63 along the travel route. The facility search means searches for facilities in the first search region using all facility information as search targets, and searches for facilities in the third search region using facilities having DTS as search targets. ing.

(C) Third method The first search area 63 is set to perform a search for all facilities regardless of the presence or absence of DTS, and the second search area 64 is set to limit the search to facilities with DTS. I do. Then, after deleting one of the overlapping facilities (facility with DTS existing in the first search area), both search results are integrated. In addition, when integrating both search results, it can also comprise so that it may store in RAM24 by overwrite preservation | save.
(D) Fourth Method The second search area 64 is set to search for all facilities, and the DTS-free facility in the third search area is searched and deleted from the search results.

  In this way, the navigation device 1 uses the first distance as a threshold for searching for facilities without DTS, and the second distance larger than the first distance as a threshold for searching for facilities with DTS. It is possible to search for facilities with DTS that do not hit in the search.

By the way, although the facilities with DTS to be searched increase as the second distance increases, the travel time away from the travel route 62 to the facility with DTS increases, and the time reduction effect by using the DTS is offset. It will be.
Therefore, the magnitude of the second distance is determined within a range in which the time reduction effect can be expected based on the average time of the loss time based on the distance from the travel route 62.

In addition, the second distance of the second search area in which only the facility with DTS is searched can be a variable instead of a fixed value.
For example, the second distance is dynamically changed depending on the type of the travel route 62, road conditions such as the presence or absence of traffic congestion on the travel route 62, the time zone, and the like. In other words, the second distance is set to be large for main trunk lines such as national roads, and small for small roads such as prefectural roads and city roads. Further, when there is a traffic jam on the travel route 62, the second distance is set to be larger than that in the case where the traffic has not occurred. Also, for crowded time zones such as work hours and return time zones, the second distance is set to be larger than other time zones.

FIG. 2B is a diagram for explaining a modification of the range in which the search along the route is performed.
When there is a facility with DTS on the opposite lane side, it is necessary to make a right turn at least twice in order to stop by and return to the original travel route.
Therefore, in this modification, by setting the second distance on the opposite lane side to be smaller than the second distance on the traveling lane side, the oncoming lane side is limited to facilities with DTS closer to the traveling route 62. It is made to do.
However, also in this modification, the second distance on the opposite lane side is set to be equal to or greater than the first distance.

FIG. 2B shows the case of left-hand traffic, and the navigation device 1 sets the second distance on the travel lane side of the second search area 64 to 100 m, and sets the second distance on the opposite lane side to the travel lane side. Shorter than the first distance (for example, 70 m).
Thereby, as shown in FIG. 2A, the facility 72e on the opposite lane side searched in the first embodiment is not searched in the present modification.
As described above, according to the present modification, the travel time to the facility is set by setting the second distance in consideration of the convenience when traveling to the facility among the facilities with DTS existing in the vicinity of the travel route 62. And the load of movement can be reduced.

Furthermore, as in the case where the second distance is not a fixed value but a variable, for example, there are many lanes and traffic on the main road, and it is difficult to turn to the opposite lane side, while prefectural roads and city roads. In the case of a living road, the number of lanes and the amount of traffic are small, and there is less difficulty in turning to the opposite lane. Therefore, when the travel route 62 is a main road, the second on the opposite lane side compared to other cases. The distance may be reduced.
Similarly, the second distance on the opposite lane side may be dynamically changed according to road conditions such as the presence or absence of traffic congestion on the travel route 62, time zone, and the like.

Next, presentation of the search result by the route search to the user will be described.
FIG. 3A is a diagram illustrating an example of a search result screen obtained by searching along a route.
The search result screen 80 is formed on the display 42 by the CPU 21 (FIG. 1) based on the search result stored in the RAM 24 by the route search.
On the search result screen 80, information on the searched facilities is displayed in a list from the top in the order from the current position 61 along the travel route 62.
As shown in the search result screen 80, the navigation device 1 distinguishes the facility from the DTS-free facility by clearly indicating the name of the retrieved facility and the facility having the DTS. In FIG. 3A, the facility with DTS is clearly indicated by attaching a symbol “D”.

Furthermore, the navigation device 1 explicitly presents that the facility that is included in the second distance range and is not included in the first distance range is outside the first distance range.
That is, the navigation device 1 distinguishes it from the facility with DTS existing in the first search region 63 by clearly indicating that the facility has the DTS present in the third search region. In FIG. 3A, for a facility with a DTS in the third search area, for example, a symbol (double circle in the figure) indicating that is attached to “× Δ lunch box” of the facility 82 is displayed. Yes. By this indication, the user can recognize that the moving distance is slightly longer in a facility with a DTS with a double circle symbol.
Note that the travel distance from the current position of the vehicle to each facility may be obtained and displayed on the search result screen 80.

FIG. 3B is a diagram showing another example of the search result screen.
The search result screen 85 includes a positional relationship with the current position 61 by displaying a facility symbol at the position where the facility is located on the road map displaying the current position 61 and the travel route 62. It is an explicit one.
According to FIG. 3B, facilities 87 and 89 (hamburger shop) are displayed. Depending on the presence or absence of the explicit symbol “D”, the user has moved the facility 87 without DTS, and the facility 89 is DTS. You can understand that it is a facility.
By displaying each facility symbol at a corresponding position on the road map, the user can intuitively know the distance to each facility. However, the distance may be displayed on the map.
The user can determine whether to use the facility 87 without DTS existing along the travel route 62 or to use the facility 89 of the facility with DTS that deviates from the travel route 62.

In addition, when the user selects each facility displayed on the search result screen 85 by a screen touch or the like, the navigation device 1 causes the route to move as the transit facility to the selected facility and the route to return to the travel route 62 from the facility ( It is also possible to search for (route) and display it on the screen.
In FIG. 3B, when the user selects the facility with DTS 89, a waypoint search is performed and the route 65 is displayed on the screen. As a result, the user can safely drop in at the DTS facility and return to the original travel route 62.
In addition, although not explicitly shown in FIG. 3B, a message to that effect may be displayed for a facility with DTS that exists in the third search area, for example, the facility 89.

Further, as a modification when displaying the search results on the search result screens 80 and 85 shown in FIGS. 3A and 3A, the waiting time when the DTS of the facility is used as the facility information of the facility with the DTS is increased. If it can be acquired, the waiting time can be used as follows.
For example, in a facility whose waiting time is equal to or greater than a predetermined threshold (for example, waiting time of 5 minutes or longer), the staying time becomes long after all, so that is indicated on the search result screen 80. For example, a message indicating that the waiting time is long or a waiting time is displayed.
Alternatively, a facility with DTS whose waiting time is equal to or greater than a predetermined threshold may be searched along a route as a facility without DTS.

As for the waiting time of the facility with DTS, for example, the crowded time zone is heard in advance from the facility with DTS and registered in the facility information file 52.
Or you may make it upload to a server apparatus from a facility with DTS, and the navigation apparatus 1 may communicate with the said server and obtain this.
As described above, the navigation apparatus 1 includes a waiting time acquisition unit that acquires the waiting time of a facility with a DTS, and the presenting unit selects a facility with a DTS whose acquired waiting time is equal to or greater than a predetermined threshold. Presented separately from facilities with DTS that are less than the threshold.

When the user selects a specific facility from the search results shown in FIGS. 3A and 3B, the navigation apparatus 1 provides information for the user to use the facility.
For example, the navigation device 1 displays detailed information of the facility on the display 42 and outputs sound from the speaker 43. In addition, by displaying on the display 42 a via route 65 having the selected facility as a transit point, guidance to the facility is performed.

Next, details of the route search processing will be described.
FIG. 4 is a flowchart for explaining search along a route performed by the navigation device 1.
The search along the route is performed by the CPU 21 (FIG. 1) executing the navigation program or the search program along the route stored in the ROM 22 or the information storage device 50.
The search along the route is based on the premise that the CPU 21 acquires the travel route 62 of the vehicle and stores it in the RAM 24. The travel route 62 is acquired by the CPU 21 searching for the travel route from the current position of the vehicle or the start point designated by the user to the destination using the navigation program in the own device, and stored in the RAM 24. Alternatively, the travel route searched for by the external device may be acquired via the communication interface 25 and stored in the RAM 24.
In accordance with the navigation program, the CPU 21 performs various guidance of the travel route 62 by screen display or voice output while detecting the current position by the current position detection device 10.

In parallel with the guidance of the travel route 62, the CPU 21 monitors whether or not there is a search request along the route from the user (step 5).
This request for search along route is determined to have been requested when the user selects search along route on the menu screen displayed on the display 42. More specifically, the CPU 21 determines that there is a request when the facility search is selected on the menu screen and the search along the route is selected on the facility search screen. However, various settings can be made for the user interface for selecting the search along the route.

If there is no request for searching along the route (step 5; N), the CPU 21 continues monitoring whether there is a request for searching along the route from the user in step 5.
When there is a search request along the route (step 5; Y), the CPU 21 receives an input of a search word from the user (step 10).
That is, the CPU 21 displays a list of search terms such as “restaurant”, “convenience store”, and “gas station” that can be selected by the user on the display 42 based on the search request along the route, and inputs the search term selected by the user. Accept as.

When receiving the input of the search term, the CPU 21 determines whether or not there is a facility without DTS in the first search area 63 (step 15).
That is, as shown in FIG. 2A, the CPU 21 sets the first search area 63 along the travel route 62 with the current position 61 on the map 60 as a starting point. The CPU 21 expands the map based on the map data, the current position 61, and the travel route 62 in the virtual space on the RAM 24 and logically performs this setting on the expanded data.
Then, the CPU 21 searches the first search area 63 using the facility information developed in the RAM 24 to determine whether there is a DTS-free facility corresponding to the search word.

  When there is a facility without DTS in the first search area 63 (step 15; Y), the CPU 21 stores the facility without DTS in the first search area 63 in the RAM 24 as a search result (step 20). On the other hand, when there is no facility without DTS (step 15; N), the CPU 21 proceeds to step 25.

Next, the CPU 21 similarly sets the second search area 64 in the map 60, and determines whether or not there is a facility with DTS corresponding to the search word in the second search area 64 (step 25).
When there is a facility with DTS in the second search area 64 (step 25; Y), the CPU 21 stores the facility with DTS in the second search area 64 in the RAM 24 as a search result (step 30). On the other hand, when there is no facility with DTS (step 25; N), the CPU 21 proceeds to step 35.

  As a result of the above processing, the RAM 24 has a DTS-free facility located in the first search area 63 and a DTS-equipped facility located in the second search area 64 that are targeted for search by the search word entered by the user. Facility information is stored.

Next, the CPU 21 uses the facility information of the retrieved facilities, and the search result screen data to be displayed on the search result screen 80 (FIG. 3A) or the search result screen 85 (the same (b)). Is stored in the RAM 24 (step 35).
Next, the CPU 21 displays the search result screen 80 or the search result screen 85 on the display 42 using the search result screen data stored in the RAM 24 (step 40).
Note that the CPU 21 may create both the search result screens 80 and 85 in step 35 so that both the screens 80 and 85 can be switched and displayed by the user's selection. In this case, the first screen to be displayed may be determined in advance as one of the screens, or the screen on the most recently displayed side may be displayed.
After displaying the search result screen 80, the CPU 21 returns to another routine based on a user request such as detailed display of facility information or route guidance.

FIG. 5 is a flowchart for explaining a modified example of the search along the route performed by the navigation device 1. The same steps as those in FIG. 4 are denoted by the same step numbers, and description thereof will be simplified or omitted.
When the CPU 21 accepts the input of the search word in step 10, the CPU 21 searches all facilities existing in the first search area 63 for the facility corresponding to the search word (step 50). That is, the CPU 21 searches for all facilities that exist in the first search area 63 regardless of whether or not DTS is provided and correspond to the search word.
And CPU21 memorize | stores these in RAM24 as a search result (step 20).

Further, the CPU 21 sets the third search area as an area that does not overlap the first search area 63 in the second search area 64, and corresponds to the search word in the facility with DTS existing in the first search area. A thing is searched (step 55).
And CPU21 memorize | stores these in RAM24 as a search result (step 30).
The following is the same as FIG.

  4 or 5 described above, the navigation device 1 can search for a facility without a DTS in the first distance range from the travel route 62 and a facility with a DTS in the second distance range along the route. Can be proposed to the user.

According to the embodiment described above, the following effects can be obtained.
(1) In general, for example, a fast food restaurant with DTS has a drop-in time of only a few minutes, but it takes about one hour to eat at a restaurant. Therefore, more available facilities with DTS are searched. The effect is great. Therefore, searching for facilities with DTS that could not be searched conventionally can greatly contribute to user time management. Therefore, it is also possible to statistically obtain the stop time (average value) of the facility corresponding to each search term, and to increase the second distance as the facility has a longer stop time.
(2) Since the threshold of the search range for the facility with DTS (range of the second distance) is set larger than the threshold of the search range without the DTS (range of the first distance), the facility that can be expected to shorten the staying time You can search more.
(3) The second distance can be determined by comparing and considering the time saving effect due to the DTS-equipped facility and the time required for a stop, which is a factor that offsets this time saving effect.
(4) Since the facility without DTS existing between the outside of the first distance and the second distance is not searched, it is possible to exclude the facility that cannot expect the effect of shortening the staying time from the search.
