  The present invention relates to a travel route setting system, a travel route setting method, and a travel route setting program.

  2. Description of the Related Art Conventionally, a navigation device has been proposed in which a user can trace a road on a map displayed on a display with a finger so that a route along which the vehicle travels can be set based on the traced road (for example, a patent). Reference 1).

  In this conventional navigation device, when a user designates a road by tracing with a finger, when a plurality of roads are designated at the same time, a road with a higher grade is given priority among the designated roads. And set it as the driving route. Therefore, the user displayed a map of a scale (usually a large scale in which only high-grade roads such as highways and national roads are mainly displayed) when simply browsing the course during travel, etc., on the display. By tracing the road with a finger, the travel route can be roughly set.

FIG. 3 is a flowchart of the travel route setting process continued from FIG. FIG. 4 is a flowchart of the travel route setting process continued from FIG. FIG. 5 is a diagram illustrating a map showing the recommended route CR. FIG. 6 is a diagram showing a state where a part of the river R is instructed by the user's finger, and FIG. 6A is a diagram showing a state in which the river R is being instructed. b) is a diagram showing a state in which the instruction has been completed. FIG. 7 is a diagram illustrating a map showing a travel route. Here, in FIGS. 5, 6, and 7, the roads r <b> 1 to r <b> 6 are indicated by solid lines, but these roads are simply referred to as “roads” unless they are described separately. . 5 and 6, the recommended route CR is indicated by a dotted line. Note that the “recommended route” CR is a route searched using a known route search method such as the Dijkstra method. For example, a route with the shortest distance, a general road priority route, a high speed or a road priority route, etc. The route searched based on the travel cost corresponds to the above. Further, the number of searches for the recommended route CR is arbitrary, but it may be singular or plural. In FIG. 6, the locus L of the movement of the user's finger is indicated by a bold line, and the start point Ls of the locus L and the end point Lg of the locus L are indicated by a perfect circle. In addition, the travel route setting process is a process of setting a route from the departure point S to the destination G as a travel route, and is started after the travel route setting device 20 is powered on, for example.

  When the travel route setting process is activated, as shown in FIG. 2, in order to search for a route from the departure point S to the destination G, the control unit 26 performs a process from SA1 to SA3.

  First, the route search unit 26a waits until the departure point S and the destination G are set by accepting a user's predetermined operation through the touch panel 24 (SA1, No). Note that the setting of the departure place S is not limited to being set when a user's predetermined operation is received by the touch panel 24. For example, the current position acquired by the current position acquisition unit 21 is set as the departure place S. Also good. As for the setting of the destination G, an address input by the user or a facility specified by facility search may be set as the destination G.

  Here, when the departure point S and the destination G are set (SA1, Yes), the route search unit 26a is based on the set departure point S and the destination G and the map information acquired from the map information DB 27a. Then, the recommended route CR is searched, and as shown in FIG. 5, the searched recommended route CR is superimposed on the map displayed on the display 23 (SA2).

  Returning to FIG. 2, after the process of SA2, the route search unit 26a determines whether or not to accept a change in the recommended route CR searched in SA2 by receiving a user's predetermined operation through the touch panel 24 ( SA3). Specifically, after the processing in SA2, the display 23 is searched for in the selection area (for example, a pop-up image) for instructing the display 23 to maintain the recommended route CR searched in SA2. A selection area for instructing to change the recommended route CR is displayed. Then, when the selection area for changing the recommended route CR is selected via the touch panel 24 and the change operation of the recommended route CR is received, the route search unit 26a changes the recommended route CR searched in SA2. Determine to accept. On the other hand, when the selection area for maintaining the recommended route CR is selected via the touch panel 24 and the maintenance operation for the recommended route CR is received, the route search unit 26a changes the recommended route CR searched in SA2. It is determined not to accept.

  If it is determined that the change of the recommended route CR searched in SA2 is not accepted (SA3, No), it is not necessary to change the route set in SA2, and therefore, from SA4, as shown in FIG. Without performing the process of SA20, the travel route setting unit 26f sets the recommended route CR searched in SA2 as the travel route, and displays the set travel route superimposed on the map displayed on the display 23. (SA21). Thus, the travel route setting process is terminated, and the guide unit 26g outputs guidance information based on the travel route set in this way.

  On the other hand, in FIG. 2, when it is determined that the change of the recommended route CR searched in SA2 is accepted (SA3, Yes), the route set in SA2 is changed based on the locus L of the movement of the user's finger. In order to do this, the control unit 26 performs processing from SA4 to SA21.

  First, the detection unit 26b waits until the position of the user's finger on the map displayed on the display 23 is detected when the touch panel 24 is pressed by the user's finger (SA4, No).

  When the position of the user's finger is detected (SA4, Yes), the movement trajectory specifying unit 26c determines the map information stored in the map information DB 27a and the position of the user's finger detected in SA4. Based on the map, the locus L of the movement of the user's finger relative to the map displayed on the display 23 is specified (SA5). For example, as shown in FIG. 6, when the user's finger moves so as to trace a portion from the start point Ls to the end point Lg, a line segment in which each position from the start point Ls to the end point Lg is successively continued is known. The locus L is specified by specifying by this method.

  Returning to FIG. 2, the object determination unit 26e determines whether or not the user's finger movement locus L specified in SA5 and the object overlap based on the position coordinates of the object acquired from the map information DB 27a. (SA6). Specifically, in the determination area based on the center line of the object (for example, an area within 10 m on both sides of the center line in the actual size, etc. Specifically, it is set on both sides of the center line in parallel with the center line. Each line from the start point Ls to the end point Lg of the locus L in the area between the center line and an area located between the center line and the center line. It is determined whether or not the position coordinates are included. Here, the “center line of the object” is a line passing through the center of the line width of the object formed in a substantially linear shape as described above. For example, when the object is the river R, the river R It is a line passing through the center in the width direction. When the position coordinates of each position from the start point Ls to the end point Lg of the locus L are included in the determination area, it is determined that the locus L and the object overlap, and the end point from the start point Ls to the end point of the locus L is included in the determination area. When the position coordinates of each position reaching Lg are not included, it is determined that the locus L and the object do not overlap.

  Here, the number of objects overlapping the locus L is not limited to one. For example, in the present embodiment, as shown in FIG. 6, when the river R and the track T intersect at the intersection P, the user traces the river R with his / her finger so as to pass through the intersection P. Both the determination area based on the center line of the river R and the determination area based on the center line of the track T include any position coordinate of each position from the start point Ls to the end point Lg of the trajectory L. . Therefore, in such a case, the object determination unit 26e determines that the trajectory L overlaps both the river R and the track T objects.

  Then, returning to FIG. 2, when it is determined that the object and the trajectory L do not overlap (SA6, No), it is not necessary to specify the travel route based on the object. As shown, a normal travel route search based on the user's finger movement locus L specified in SA5 is performed (SA20), the route searched in SA20 is set as a travel route, and the set travel route is set. The map displayed on the display 23 is displayed so as to overlap (SA21). Here, a specific method of “ordinary travel route search based on the user's finger movement locus L” is arbitrary. For example, referring to the map information stored in the map information DB 27a, the display A road included in the map displayed at 23 is specified. Then, among the identified roads, a road corresponding at least partially to the locus L identified in SA5 (overlapping on the map) is identified, and the identified road is designated by the user's finger. The road indicated by In addition, the specific method of specifying the traveling direction on the road is arbitrary. For example, referring to the map information stored in the map information DB 27a for the road specified by the specified user's finger, Identify the direction of the road. Then, a direction that matches the moving direction of the position of the user's finger detected in SA4 in FIG. 2 is specified from the specified road direction, and the specified direction is specified as a traveling direction on the road. . When the road designated by the user's finger is specified in this way, the display 23 is displayed so that the user can recognize that the road has been selected in the portion overlapping the locus L on the road. To display. Although the specific method of this display is arbitrary, for example, it is a line that is slightly narrower than the road width of the road at a portion overlapping with the locus L on the road, and has a color different from the display color of the road. Superimpose lines. Thus, the travel route setting process is terminated, and the guide unit 26g outputs guidance information based on the travel route set in this way.

  On the other hand, when it is determined that the object and the trajectory L overlap (SA6, Yes), the road identifying unit 26d selects a candidate object (SA7). Specifically, when there are a plurality of objects determined to overlap with the locus L at SA6, all of the plurality of objects are selected as candidate objects, and the objects determined to overlap with the locus L at SA6. If only one exists, the one object is selected as a candidate object. In the following, the object specified by the user is selected in two stages, steps SA8 to SA10 and steps SA11 to SA13 shown in FIG. Here, an object selected as a candidate at each stage is referred to as a “candidate object”, and an object finally selected is referred to as a “target object”.

  Here, in describing the process of selecting the target object in this way, in the present embodiment, as shown in FIG. 5, the river R is actually a river Ra and a river Rb (both not shown). (The river Ra and the river Rb are not displayed separately, but are displayed as an integral river R, because a map example of a large scale is shown in FIG. 5), and the river Assume that R and the line T intersect at an intersection P. Therefore, in the present embodiment, river Ra, river Rb, and track T are selected as candidate objects in SA7.

  Next, as shown in FIG. 3, the road specifying unit 26d determines whether or not a plurality of candidate objects are running side by side in all candidate objects selected in SA7 (SA8). That is, even when a plurality of rivers are actually running side by side, when a large scale map is displayed on the display 23, the plurality of rivers are displayed as a single river as a unit. There is a case. In such a case, by automatically selecting which of the plurality of rivers is the object designated by the user, the user can select a specific object from the plurality of parallel running objects. It is possible to eliminate the trouble of performing the operation of designating the user, and it is possible to further improve the convenience for the user.

  Here, a specific determination method for determining whether or not a plurality of candidate objects are running side by side is arbitrary. For example, when there are two or more candidate objects determined to overlap with the trajectory L in SA6, and a section that overlaps with the trajectory L of these two or more candidate objects (for example, from the start point Ls to the end point Lg in FIG. 6). ), It is determined whether or not a section in which the distance between the center lines of each candidate object is within a predetermined distance (for example, 50 m in actual size) exceeds a predetermined distance (for example, 100 m in actual size). When it is determined that a plurality of candidate objects are running in parallel when it is determined that they are continuous over a predetermined distance, a plurality of candidates are determined when it is determined that the plurality of candidate objects are running side by side, and are not continuous over a predetermined distance. It is determined that the objects are not running side by side.

  When it is determined that a plurality of candidate objects are running side by side (SA8, Yes), the road specifying unit 26d obtains grade information of the plurality of candidate objects running side by side from the map information DB 27a. The grade of the candidate object is specified (SA9). Then, candidate objects are selected based on the grade information of each candidate object specified in SA9 (SA10). Specifically, for example, when the river R is actually composed of the river Ra and the river Rb as in the present embodiment, the grade information of the river Ra and the river Rb is acquired from the map information DB 27a, and the river Ra Is identified as “first-class river” and river Rb is “second-class river”, river Rb, which is a low-grade river, is excluded from candidate objects, and river Ra and track T, which are objects other than river Rb Are selected as candidate objects. When the grades of the plurality of candidate objects running in parallel are the same, for example, the distance between the center line of each candidate object and the trajectory L is calculated, and the candidate object whose distance is longer is selected as a candidate. It may be excluded from the object.

  On the other hand, when it is determined that the plurality of candidate objects are not running side by side (SA8, No), the road specifying unit 26d does not need to select a candidate object from among the plurality of candidate objects running in parallel. In selecting a candidate object in SA10 without performing the process in SA9, the candidate object selected in SA7 in FIG. 2 is continuously selected as a candidate object.

  Subsequently, the road specifying unit 26d determines whether or not a plurality of candidate objects intersect each other in the candidate objects selected in SA10 in FIG. 3 (SA11). That is, for example, as shown in FIG. 6, there is a situation where a plurality of candidate objects intersect (in FIG. 6, the river R and the track T intersect at the intersection P). In this case, it is not clear which object is designated by the user at the intersection P. However, in actuality, when the user's finger traces the river R, the river R and the track T intersect each other at the intersection P, and therefore, the user has traced the track T unintentionally. Is not considered the specified object. Therefore, by automatically excluding objects that have been unintentionally traced as a result of the intersection of multiple objects from the candidate objects and selecting an appropriate object, the user can select these multiple intersecting objects. It is possible to omit the trouble of performing an operation of designating a specific object from among the items, and it is possible to further improve the convenience for the user.

  Here, as a specific determination method of whether or not a plurality of candidate objects intersect with each other, for example, based on the intersection coordinates of candidate objects acquired from the map information DB 27a, a target based on the intersection coordinates It is determined whether or not the locus L is included in the area (for example, within a radius of 10 m in actual size). When it is determined that the trajectory L is included, it is determined that a plurality of candidate objects intersect, and when it is determined that the trajectory L is not included, the plurality of candidate objects do not intersect with each other. judge.

  If it is determined that a plurality of candidate objects intersect (SA11, Yes), the degree of overlap with the locus L of each candidate object is specified (SA12). Here, the “overlap degree” is a value serving as an index for selecting an appropriate object as a candidate object, and is a value indicating the degree of overlap between the locus L and the object. Specifically, the degree of overlap is the ratio of the length of the trajectory L included in the determination area (same as above) with respect to the center line of the object in the length from the start point Ls to the end point Lg of the trajectory L. And expressed as a percentage. For example, in the present embodiment, as shown in FIG. 6B, in the section from the start point Ls to the end point Lg of the trajectory L, the trajectory L is consistent within the determination area based on the center line of the river Ra. Therefore, the degree of overlap of the river Ra in the trajectory L is high, for example, 100% is specified. On the other hand, since the trajectory L is included only in the vicinity of the intersection point P in the determination area based on the center line of the track T, the degree of overlap of the track T in the trajectory L is low, for example, specified as 5%.

  Next, candidate objects are selected based on the degree of duplication specified in SA12 in FIG. 3 (SA13). Specifically, the duplication rates of the objects specified in SA12 are compared, an object with a lower duplication degree is excluded from candidate objects, and an object with a higher duplication rate is selected as a candidate object. For example, in the present embodiment, since the degree of overlap of river Ra (100%) is higher than the degree of overlap of track T (5%), river Ra is specified as a candidate object.

  On the other hand, when it is determined that the plurality of candidate objects do not intersect with each other (SA11, No), the road specifying unit 26d does not need to select a candidate object from among the plurality of intersecting candidate objects. In selecting a candidate object in SA13 without performing the above process, the candidate object selected in SA10 is continuously selected as a candidate object.

  Next, the road specifying unit 26d specifies the object finally selected as the candidate object in SA13 through the processing from SA7 in FIG. 2 to SA13 in FIG. 3 as the target object. For example, in the present embodiment, river Ra, river Rb, and track T are selected as candidate objects in SA7, river Rb is excluded from candidate objects in SA10, and track T is excluded from candidate objects in SA13. Specifically, the river Ra selected as a candidate object in SA13 is specified as a target object.

  Next, as shown in FIG. 4, the road specifying unit 26d searches for a road located in the vicinity of an overlapping portion with at least a part of the locus L in the target object (SA15). Here, “neighboring” indicates that the object is located within a predetermined distance, and one index indicates, for example, a distance between which the user can recognize the target object. In the present embodiment, the road specifying unit 26d searches for a road included in a determination area based on the center line of the target object (for example, an area within 50 m on both sides of the center line in the actual size). By doing so, a road located in the vicinity is searched.

  Next, the road specifying unit 26d determines whether or not there are a plurality of roads searched in SA15 (SA16). Here, “there are a plurality of roads” means that the route that can travel in the vicinity of the target object is not limited to one, for example, not only when two roads actually run in parallel, This includes the case where one road is bifurcated on the way. Here, as a specific method for making such a determination, based on the link data acquired from the map information DB 27a, an overlapping portion of the target object with the locus L (from the start point Ls to the end point Lg in the present embodiment). In the vicinity of (part), it is determined whether or not there are two roads running in parallel or a road that branches.

  If it is determined that there are a plurality of searched roads (SA16, Yes), the road specifying unit 26d specifies the grade of each road by acquiring the grade information of the plurality of roads from the map information DB 27a ( SA17). Next, the road specifying unit 26d specifies the distance from each road to the target object (SA18). Here, as the “distance to the target object”, for example, an average distance from the center line of each road to the center line of the target object or the shortest distance may be used.

  Then, the road specifying unit 26d specifies only one target road that is a target road for guidance based on the grade of each road specified in SA17 and the distance from each road specified in SA18 to the target object ( SA19). Note that the specific specifying method is arbitrary, for example, from a road located in the vicinity of the target object searched in SA15 to a low-grade road specified in SA17 or a target object specified in SA18. A road with a large distance is excluded, and the remaining road is specified as a target road. In addition, roads that cannot pass (for example, one-way roads) and roads that are difficult to pass (for example, roads in a traffic jam) may be excluded from the target roads. In addition, when it is not determined that there are a plurality of searched roads (when it is determined that only one searched road exists) (SA16, No), the road specifying unit 26d determines that only one road exists. Specify the target road.

  When there is no road that can be specified as the target road in the process of SA19, the object excluded from the candidate objects in the process of SA10 shown in FIG. 3 is specified as the target object (SA14), and the target object is shown in FIG. The processing from SA15 to SA19 may be executed again. Even when the processing from SA15 to SA19 is executed again in this way, if there is no road that can be identified as the target road in the processing of SA19, it is excluded from the candidate objects in the processing of SA13 shown in FIG. The object may be specified as a target object (SA14), and the processes from SA15 to SA19 shown in FIG. 4 may be executed again for the target object.

  Next, the route search unit 26a searches for a travel route including the target road identified in SA19 (SA20). Specifically, as shown in FIG. 7, the first route C1 from the departure point S to the target road start point Cs that is the start point of the target road, and the target road end point Cg that is the end point of the target road to the destination G. The second route C2 is searched using a known route search method such as Dijkstra method. Then, a route from the departure point S to the destination G via the first route C1, the target road, and the second route C2 is set as a travel route, and the travel route thus set is displayed on the display 23. Is overlaid on the map displayed at (SA21). At this time, the display of the recommended route CR displayed on the display 23 in SA2 is canceled. Thus, the travel route setting process is terminated, and the guide unit 26g outputs guidance information based on the travel route set in this way.

(effect)
As described above, according to the present embodiment, a road located in the vicinity of an overlapping portion with at least a part of the movement locus L of the user's finger or instruction means in a predetermined type of object is specified, and the specified road is Since the route including the road is set as the travel route, even when a large scale map is displayed on the display 23, the route including the road located in the vicinity of the predetermined type of object designated by the user is set as the travel route by a simple operation. It becomes possible to set, and the convenience of the user can be improved.

  In addition, when there are a plurality of roads located in the vicinity of the overlapping portion with at least a part of the locus L in the predetermined type of object, the road having the highest road grade is identified from the plurality of roads. Since a route including a road is set as a travel route, even when there are a plurality of roads located in the vicinity of the overlapping portion, an operation for designating a specific road from the plurality of roads is not performed. It is possible to set a travel route, and it is possible to further improve user convenience.

  Further, when there are a plurality of roads located in the vicinity of an overlapping portion with at least a part of the locus L in the predetermined type of object, the road closest to the predetermined type of object is specified and specified. Since the route including the selected road is set as the travel route, even when there are a plurality of roads located near the overlapping portion, an operation for designating a specific road from the plurality of roads is performed. Therefore, it is possible to set the travel route without any further improvement in user convenience.

  In addition, when a plurality of predetermined types of objects are running in parallel, a predetermined type of object having the highest class of the object among the plurality of predetermined types of objects is identified, and a trajectory in the specified predetermined type of objects Since a route including a road located in the vicinity of an overlapping portion with at least a part of L is set as a traveling route, even when a plurality of predetermined types of objects are running in parallel, the plurality of predetermined types It is possible to set a travel route without performing an operation for designating a specific predetermined type of object from among the objects, and it is possible to further improve user convenience.

  In addition, when a plurality of predetermined types of objects intersect, the predetermined type of object having the largest number of overlapping portions with the locus L among the plurality of predetermined types of objects is specified, and the specified predetermined type of objects Since a route including a road located in the vicinity of an overlapping portion with at least a part of the locus L in the object is set as a travel route, even if a plurality of predetermined types of objects intersect, It is possible to set a travel route without performing an operation for designating a specific predetermined type of object from predetermined types of objects, and it is possible to further improve user convenience.

  In addition, since the predetermined types of objects include the track T and the river, even when a large scale map is displayed on the display 23, the destination G can be reached from the departure point S along the track T or the river by a simple operation. It is possible to set a travel route that leads to, and to improve user convenience.
