[0011] An embodiment of the present invention will be described with reference to FIG.

[0012] As shown in FIG. 1, the display control device 1 includes a classification means 111A and a display control means 111B, and is connected to a display unit 2.

[0013] The classification means 111A classifies a plurality of points into groups based on their respective positions.

[0014] The display control means 111B causes the display unit 2 to display guidance information that indicates a group including a location as a guidance target. A group does not necessarily have to include multiple locations, and a group including only one location is also called a group. As a result, guidance information is displayed with multiple locations as one guidance target, so that the user can quickly grasp the guidance target.

[0015] The display control means 111B displays information representing at least one location included in the group as at least a part of the guidance information. The information representing the location is, for example, a name representing the location (facility name, etc.), an administrative notation representing the location (for example, 1-1-1 XX town, XX city, XX prefecture), an icon representing the location, etc. As a result, since the information representing at least one location is displayed as the guidance information, the user can guess other locations included in the group (guidance target).

[0016] The display control device 1 may further include a current position acquisition means 111C that acquires information indicating the current position of the display control device 1. The information indicating the current position is, for example, information indicating latitude and longitude.

[0017] The display control means 111B may display guidance information based on the current position, based on the positional relationship between the current position and the guidance target. For example, when displaying information indicating the current position and guidance information, if the position of the group (guidance target) is northeast of the current position, the display control means 111B displays a map that displays guidance information at a position northeast of the information indicating the current position. This allows the user to know at a glance in which direction the group (guidance target) is located.

[0018] The classification means 111A may classify a plurality of points into groups according to the distance or travel time from the current position. The distance may be a straight-line distance or a travel distance. For example, the points may be grouped into points less than 5 km from the current position and points 5 km or more away, or points may be grouped into points less than 15 minutes away from the current position and points 15 minutes or more away.

[0019] Furthermore, the display control means 111B may display information representing at least one of the points included in the group, the point farthest from the current position or the point closest to the current position, as at least a part of the guidance information, which allows the user to roughly grasp the geographical range of the group (guidance target).

[0020] The display control device 1 may further include a selection means 111D for selecting a destination candidate point according to historical information related to the point. The historical information related to the point may be, for example, information indicating a history of a user's search for a point, information indicating a history of the user's visit to or passing through the point, etc.

[0021] The sorting means 111A may sort the destination candidate points selected by the selection means 111D into groups, thereby making it possible to display destination candidate points that are highly likely to be selected as the user's destination.

[0022] Furthermore, the display control means 111B may display information representing the most recently visited or searched destination candidate points among the destination candidate points included in the group as at least a part of the guidance information based on the history information, thereby allowing the user to roughly grasp the location of the group (guidance target).

[0023] Furthermore, the selection means 111D calculates an evaluation value for the location based on the historical information and selects the location whose evaluation value meets a predetermined criterion as a candidate destination location, and the display control means 111B displays information representing the location with the highest evaluation value among the locations included in the group as at least a part of the guidance information.

[0024] The display control device 1 may further include a branch point acquisition means 111E that acquires information indicating the position of a branch point in the traveling direction of the display control device 1.

[0025] The classification means 111A may classify the multiple locations into groups according to the direction from the branch point. In this way, even if there are multiple locations in either direction from the branch point, the guidance information is displayed for each location as a single guidance target, so that the user can quickly understand these locations.

[0026] The display control means 111B displays guidance information only for groups that include a number of locations equal to or greater than a threshold, and the threshold may be set based on at least one of the size of the display unit 2, the character size of characters displayed on the display unit 2, or a value set by the user. For example, when the size of the display unit 2 (screen) is small or the character size is large, it is difficult to simultaneously display information representing multiple locations. Therefore, by setting the threshold to a small value, guidance information can be displayed as a single guidance target instead of simultaneously displaying multiple locations, making it easier for the user to view.

[0027] The sorting means 111A may sort a plurality of points into groups based on their respective positions, and further sort the groups containing the points into sub-groups that are further subdivided in accordance with predetermined criteria, and the display control means 111B may display guidance information that represents the groups as guidance targets, including at least information representing the points included in each sub-group. EXAMPLES

[0028] Next, a specific example corresponding to the above-described embodiment will be described.

[0029] The following embodiment will be described with reference to Figures 2 to 6. Note that the following embodiment is an embodiment in which the present invention is applied to a navigation device mounted on a vehicle.

[0030] [1. Overview of navigation device] First, an overview of the destination suggestion function of the navigation device in this embodiment will be described. The destination suggestion function is a function that, when the user is driving without setting a destination, estimates destination candidate points from points that the user has visited or searched for in the past and displays them on a directional sign on the screen.

[0031] For the purpose of the destination presentation function, the navigation device routinely records history information indicating destination search history, visit (via) history, etc. (regardless of whether the destination presentation function is in operation or not).

[0032] The navigation device calculates a score (one example of an "evaluation value") for each point based on history information using a conventionally known method, as shown in Fig. 2, for estimating a candidate destination point for the user. If there are many points for which scores are to be calculated, the scores may be calculated excluding points that are outside a predetermined range in distance or travel time from the current position of the vehicle (navigation device) and points that have been searched for or visited (passed by) for a predetermined period of time or more. Fig. 2 shows an example in which scores are calculated for a total of nine points, points A to I.

[0033] Fig. 3 is a diagram showing the positional relationship of the points for which the scores were calculated, and the vehicle's position is represented by vehicle mark C. The navigation device selects points with a score of 15 or more (an example of a "point that satisfies a predetermined criterion") as destination candidate points. That is, in the example of Fig. 2, points A to G are selected as destination candidate points, and points H and I are not selected.

[0034] The navigation device divides (groups) the destination candidate points A to G into groups according to the location of each point. Specifically, information indicating the location of branch point F1 in the traveling direction of the vehicle (navigation device) is acquired, and the destination candidate points are divided into groups according to the direction from branch point F1. In the example of FIG. 3, points A and B, which are located in the direction of turning left from branch point F1, are grouped into group G1. Similarly, points C to G, which are located in the direction of turning right from branch point F1, are grouped into group G2. Note that points H and I, which are located in the direction going straight from branch point F1, are not destination candidate points because their scores are less than 15 points, and are therefore not included in the grouping.

[0035] The navigation device judges whether the number of destination candidate points included in groups G1 and G2 is three or more (an example of a "threshold value"). For group G1, which does not include three or more destination candidate points, a directional sign screen 500 is displayed that displays the names of the destination candidate points as is, as shown in FIG. 4. On the other hand, for group G2, which includes three or more destination candidate points, a directional sign screen 500 is displayed that displays guidance information indicating the group as a guidance target ("towards point C / point G"). At this time, the navigation device displays guidance information including the names of point C, which is the closest point from the current position, and point G, which is the farthest point, from the destination candidate points included in group G2.

[0036] This allows the user to know the direction from the current location to the destination candidate points even when the user is driving without setting a destination. Also, for the destination candidate points included in group G2, not all of them are displayed, but guidance information showing group G2 as a guidance target is displayed, so the user can quickly understand the guidance target.

[0037] [2. Configuration of navigation device] Next, the configuration of the navigation device NV according to this embodiment will be described with reference to Fig. 5. As shown in Fig. 5, the navigation device NV includes a control unit 211, a storage device 212 including a HDD or the like, an input device 213 including a keyboard or a remote controller, a touch panel or the like, a display unit 214, a bus line 215, an input / output interface unit 220, a vehicle speed sensor 221, an angular velocity sensor 222, an acceleration sensor 223, a steering angle sensor 224, a GPS receiving unit 225, a data transmitting / receiving unit 226, and a wireless communication unit 227.

[0038] The vehicle speed sensor 221 detects the current speed of the vehicle by using a speed detection process using a vehicle speed pulse obtained from the vehicle equipped with the navigation device NV, and outputs the speed data. The angular velocity sensor 222 detects the angular velocity of the vehicle, for example, a change in direction, and outputs the angular velocity data and the relative direction data per unit time. The acceleration sensor 223 detects the acceleration of the vehicle, for example, in the forward and backward directions, and outputs the acceleration data per unit time. The steering angle sensor 224 detects the steering angle of the vehicle, and outputs the steering angle data. The GPS receiving unit 225 receives navigation radio waves from a GPS satellite, and outputs the latitude, longitude, and altitude data, which are the vehicle position information (current position information), absolute direction data in the traveling direction of the vehicle, GPS speed data, and the like, as GPS positioning data. The data transmitting / receiving unit 226 performs processing related to the transmission and reception of data to and from a server device via a network. The wireless communication unit 227 performs processing related to wireless road-to-vehicle communication and vehicle-to-vehicle communication.

[0039] The storage device 212 stores various programs such as an operating system and application programs (including a program for implementing a destination presentation function). Note that the various programs may be acquired, for example, from a server device or the like via a network, or may be read and executed from a recording medium such as a CD, DVD, or USB memory.

[0040] The storage device 212 also stores map image data for displaying a map on the display unit 214, map information used when searching for a route, road link information, and the like.

[0041] Furthermore, the storage device 212 stores information necessary for realizing the destination presentation function, such as history information indicating the user's destination search history and point visit history (route history), and branch point information (information indicating the position of the branch point).

[0042] The input device 213 is configured with a touch panel, a keyboard, a mouse, other controllers, etc., and receives input operations from a user and transmits operation signals indicating the contents of the operation to the control unit 211.

[0043] The display unit 214 displays various display data under the control of the control unit 211. The display unit 214 is configured with a graphics controller 214a, a buffer memory 214b consisting of a memory such as a VRAM (Video RAM), a display 214c consisting of a liquid crystal display, etc. In this configuration, the graphics controller 214a controls the entire display unit 214 based on control data sent from the control unit 211 via a bus line 215. The buffer memory 214b also temporarily stores image information that can be displayed immediately. Then, an image is displayed on the display 214c based on the image data output from the graphics controller 214a. The display 214c displays a directional sign screen 500 (see FIG. 4, etc.).

[0044] The control unit 211 is composed of a CPU 211a for controlling the entire control unit 211, a ROM 211b in which a control program for controlling the control unit 211 and the like are stored in advance, and a RAM 211c for temporarily storing various data. The control unit 211 is connected to a vehicle speed sensor 221, an angular velocity sensor 222, an acceleration sensor 223, a steering angle sensor 224, and a GPS receiving unit 225 via a bus line 215 and an input / output interface unit 220, and controls the entire navigation device based on speed data, angular velocity data, relative direction data, steering angle data, GPS positioning data, absolute direction data of the vehicle's traveling direction, acceleration data, and the like outputted from each of them, and also controls the operation of each of the various components such as a display unit 214.

[0045] [3. Example of operation of navigation device NV] Next, an example of the operation of the navigation device NV during the operation of the destination presentation function will be described with reference to the flowchart of FIG.

[0046] First, the control unit 211 of the navigation device NV calculates the score of a location based on the history information recorded in the storage device 212 (step S11). The control unit 211 may calculate the score by narrowing down the locations to the current location of the vehicle and the location in the traveling direction of the vehicle. A conventionally known method may be used to calculate the score.

[0047] Next, the control unit 211 selects points with a score of 15 or more as destination candidate points (step S12). Although not shown, if there is no point with a score of 15 or more, the flow chart ends.

[0048] Next, the control unit 211 identifies the next junction to be reached from the junction information recorded in the storage device 212, the current position of the vehicle, and the traveling direction of the vehicle (step S13).

[0049] Next, the control unit 211 groups the destination candidate points selected in the process of step S12 based on the branch point identified in the process of step S13 (step S14). At this time, the control unit 211 groups the destination candidate points for each direction branching at the branch point.

[0050] Next, the control unit 211 selects one group from among the groups grouped in the process of step S14 (step S15).

[0051] Next, the control unit 211 determines whether the group selected in the process of step S15 includes three or more locations (one example of a "threshold value") (step S16). At this time, if the control unit 211 determines that the group selected in the process of step S15 includes three or more locations (step S16: YES), it determines a display mode of guidance information including the names of the locations closest and farthest from the current position of the vehicle among the destination candidate locations included in the group selected in the process of step S15 (step S17). On the other hand, if the control unit 211 determines that the group selected in the process of step S15 does not include three or more locations (step S16: NO), it determines a display mode in which the destination candidate locations included in the group selected in the process of step S15 are displayed as they are (step S18).

[0052] Next, the control unit 211 judges whether or not there is a group that has not been selected in the process of step S15 among the groups grouped in the process of step S14 (step S19). At this time, if the control unit 211 judges that there is a group that has not been selected (step S19: YES), the control unit 211 proceeds to the process of step S15. On the other hand, if the control unit 211 judges that there is no group that has not been selected (step S19: NO), the control unit 211 then displays the direction sign screen 500 that displays the points and groups in the display mode determined in the process of step S17 or step S18, and ends the process shown in the flowchart. That is, for the group whose display mode has been determined in the process of step S17, guidance information including the points that are closest to the current position of the vehicle and the points that are farthest from the current position of the vehicle are displayed (for example, "towards point C / point G" in FIG. 4), and for the group whose display mode has been determined in the process of step S18, the names of the points included in the group are displayed as they are (for example, "point A" and "point B" in FIG. 4) on the screen of the display 214c (an example of a "display unit").

[0053] As described above, according to the navigation device NV of this embodiment, the control unit 211 (an example of a "classifying means" and "display control means") classifies a plurality of destination candidate points (an example of a "point") into groups based on their respective positions, and displays guidance information representing the group including the destination candidate points as guidance targets on the screen of the display 214c (an example of a "display unit"). As a result, guidance information is displayed with a plurality of destination candidate points as one guidance target, so that even if the guidance target is a plurality of destination candidate points, the user can quickly grasp the guidance target.

[0054] Furthermore, the control unit 211 of the navigation device NV according to this embodiment displays information representing at least one of the destination candidate points included in the group ("Point C", "Point G") as at least a part of the guidance information ("Towards Point C / Point G"). This allows the user to guess the other destination candidate points included in the group.

[0055] Furthermore, the control unit 211 (an example of a "current position acquisition means") of the navigation device NV according to this embodiment acquires information indicating the current position, and displays guidance information based on the positional relationship between the current position and the guidance target, with the current position as a reference. This allows the user to know at a glance in which direction the group (guidance target) is located.

[0056] Furthermore, the control unit 211 of the navigation device NV according to this embodiment displays, as at least a part of the guidance information, names of the destination candidate point farthest from the current location and the destination candidate point closest to the current location among the destination candidate points included in the group. This allows the user to roughly grasp the geographical range of the group (guidance target). Note that information representing at least one of the destination candidate points farthest from the current location or the destination candidate point closest to the current location may be displayed as at least a part of the guidance information.

[0057] Furthermore, the control unit 211 (an example of a "selection means") of the navigation device NV according to this embodiment selects destination candidate points according to historical information about the points, and classifies the destination candidate points as points into groups. This makes it possible to display destination candidate points that are likely to be selected as the user's destination.

[0058] Furthermore, the control unit 211 (an example of "branch point acquisition means 111E") of the navigation device NV according to this embodiment acquires information indicating the position of a branch point in the traveling direction of the vehicle (navigation device NV), and separates multiple destination candidate points into groups depending on which direction they are located from the branch point. As a result, when there are three or more destination candidate points located in any direction from the branch point, guidance information is displayed as one guidance target, so that the user can quickly grasp these destination candidate points.

[0059] In this embodiment, the present invention is described as being applied to an in-vehicle navigation device NV, but it can also be applied to portable navigation devices, smartphones, tablet terminals, PCs, etc. on which a navigation application program is installed.

[0060] [4. Modifications] Next, modified examples of the above embodiment will be described. Note that the modified examples described below can be combined as appropriate.

[0061] [4.1. Variation 1] In the above embodiment, the control unit 211 displays guidance information including the names of the points closest and farthest from the current location for a group including three or more candidate destination points. Alternatively or in addition to this, after selecting points with a score of 15 points or more as candidate destination points, information (e.g., the name) representing the point with the highest score (see FIG. 2) among the points included in the group may be displayed as at least part of the guidance information, as shown in FIG. 7.

[0062] Also, as shown in Fig. 2, the number of days since the user visited (passed by) or searched for each location may be stored in the storage device 212, and the control unit 211 may display information (for example, name) representing the most recently visited or searched destination candidate location (see Fig. 2) among the destination candidate locations included in the group as at least a part of the guidance information, as shown in Fig. 8. This allows the user to roughly grasp the location of the group (guidance target).

[0063] [4.2. Variation 2] In the above embodiment, the control unit 211 groups the destination candidate points for each direction branching at the branch point in the process of step S14, but instead, the control unit 211 may divide the multiple destination candidate points into groups according to the distance from the current position or the travel time from the current position. For example, as shown in Fig. 9, when a vehicle represented by a vehicle mark C travels on a single road, if 5 km is set as the threshold indicating the boundary B1, the destination candidate points are divided into group G3 including points R and Q that are destination candidate points less than 5 km from the current position, and group G4 including points S, T, and U that are destination candidate points 5 km or more away, and if 15 minutes is set as the threshold indicating the boundary B1, the destination candidate points are divided into group G3 including points R and Q that are destination candidate points less than 15 minutes away from the current position, and group G4 including points S, T, and U that are destination candidate points 15 minutes or more away. Then, as shown in FIG. 10, the control unit 211 displays information representing the locations for group G3 (a group not including three or more locations) as is, and displays guidance information including information representing any of the locations included in group G4 (for example, the location with the highest score, the location closest to the current location, the location farthest from the current location, or the location most recently visited or searched for) for group G4 (a group including three or more locations). This allows information on both the location closest to the current location and the location farthest from the current location to be displayed on the directional signboard even if there are multiple destination candidate locations in the same travel direction, thereby preventing only one of the locations from being displayed. Note that this modified example can be applied when, as a result of grouping destination candidate locations for each direction branching at a branch point in the process of step S14 in FIG. 6, only one group for one direction is generated (for example, when all destination candidate locations are located in a straight line).

[0064] Furthermore, as shown in FIG. 11, the control unit 211 groups the locations into group G5 including points K and J, which are candidate destination points in the direction of a left turn at branch point F2, and group G6 including points L, M, N, O, and P, which are candidate destination points in the direction of a right turn at branch point F2. As a result, if the maximum distance between points included in the same group (the distance between the point closest to the current position and the point farthest from the current position) is equal to or greater than a threshold value (e.g., 20 km), the group may be further divided to create smaller groups. For example, in the example of Figure 11, if group G6 is further subdivided because the distance between points L and P included in group G6 is more than 20 km, if the threshold indicating boundary B2 is set to 5 km from branch point F2 (the distance from the current position may be set), the control unit 211 will divide the grouping into group G7 (an example of a "subdivision group") including points L and M, which are candidate destination points less than 5 km from branch point F2, and group G8 (an example of a "subdivision group") including points N, O, and P, which are candidate destination points more than 5 km away. 12, the control unit 211 displays information representing points for group G5 (a group not including three or more points) as is, and displays guidance information including at least information representing any point (e.g., the point with the highest score, the point closest to the current position, the point farthest from the current position, the point most recently visited or searched) of points included in group 7, which is further subdivided, and information representing any point (e.g., the point with the highest score, the point closest to the current position, the point farthest from the current position, the point most recently visited or searched) of points included in group 8. As a result, even if there are multiple destination candidate points in the same traveling direction after turning right at branch point F2, information on both points close to and far from the current position is displayed on the directional sign, so that it is possible to avoid displaying only one of them.

[0065] [4.4. Variation 4] In the above embodiment, the control unit 211 displays guidance information only for groups that include a number of destination candidate points equal to or greater than the threshold value of 3 in the process of step S16 in Fig. 6, but the threshold value may be set based on at least one of the size of the display unit 2 (screen), the character size of characters displayed on the display unit 2, or a value set by the user, provided that the threshold value is 2 or greater. For example, when the size of the display unit 2 (screen) is small or the character size is large, it is difficult for the control unit 211 to simultaneously display information representing multiple points, so the threshold value may be set small, or a value may be set so that the user can easily see. This improves visibility for the user.

[0066] [4.5. Variation 5] In the above embodiment, guidance information including at least the location name is displayed as information representing the location, but instead of or in addition to this, a symbol indicating the genre to which the location belongs (such as restaurant, convenience store, parking lot, etc.) or an icon showing a logo or mark representing a particular chain store, etc. may be displayed.

[0067] [4.6. Variation 6] As shown in FIG. 3, when turning right at the branch point F1 and there is a further branch point F3 beyond that, as shown in FIG. 13, the group G2 is further grouped depending on whether the branch point F3 is turned left or right, and information (e.g., the location name) representing one of the locations included in each group (e.g., the location with the highest score, the location closest to the current location, the location farthest from the current location, the location most recently visited or searched for) and guidance information including images P1 and P2 indicating which direction to turn at the branch point F3 to reach the location are displayed. This allows the user to know that there is another branch point F3 beyond the branch point F1 and which destination candidate location is located if the user turns at the branch point F3 in which direction.
