Abstract

PROBLEM TO BE SOLVED: To satisfy a need to visit again a previously visited location.SOLUTION: A travel history generating section generates a piece of information on travel history along a route where a vehicle passes. When a content reproducing section reproduces a piece of content during travelling, a storage medium stores the content information while coupling with the piece of information on travel history. After that, when the content information stored in the storage medium is designated through a touch panel, a route search section sets, based on the control of a search control section, a destination using the piece of information on travel history coupled with the designated piece of content information, and searches the route to the set destination. A guiding section guides a vehicle along the searched route.

Specifically, the GPS 4 has a function of, for example, measuring pseudo distances to four satellites observed at the same time and positioning the current location based on a difference in pseudo distances to these four satellites. The geomagnetic sensor 11 is a kind of azimuth detecting device that detects an angle representing the absolute azimuth of a vehicle based on geomagnetism. Examples of such an angle include an azimuth angle.

  The storage device 18 includes a ROM 8, a RAM 9, and a storage medium 16. The ROM 8 is an information storage medium in which various processing programs described later and other necessary information are written in advance. The RAM 9 is an information storage medium on which information necessary for executing the various programs is written and read. The RAM 9 is a memory capable of storing programs, tables, and data described later in a volatile manner.

  The storage medium 16 corresponds to first storage means, and is an information storage medium such as a CD, an HDD, or a flash memory as described above. The storage medium 16 stores rewritable content data, identification information of the content data (hereinafter appropriately referred to as content information) and map data. At this time, as a feature of the present embodiment, travel history information (corresponding to user movement history information) of the vehicle 1 is stored in the storage medium 16 in association with the content information (details will be described later).

  The arithmetic unit 20 includes a CPU 7 and a graphic controller 13. The CPU 7 has a function of performing various calculations and controls according to the various programs.

  The graphic controller 13 acquires image data, content data, and the like from a video RAM (not shown) and the storage medium 16 under the control of the CPU 7, and causes the display control circuit 14 to display on the display 15 based on these data. Have Specifically, the graphic controller 13 can cause the display 15 to display an image, a video, a moving image, or the like based on the content data under the control of the CPU 7.

It also has a function of mapping and displaying.

  The speaker 17 has a function of outputting sound of content reproduced under the control of the CPU 7, that is, sound based on the content data.

  The touch panel 21 constitutes an operating means, and is a transparent switch provided along the surface of the display area of the display 15, for example. That is, the touch panel 21 is realized by an area on the display 15. The touch panel 21 can also display spot information and route information included in the travel history information as position display means and route display means (details will be described later). And when this touch panel 21 contacts by the user who is the passenger | crew of the vehicle 1, or a passenger according to the display thing of the display area of the display 15, for example, the switch of the contact location will be turned on. .

  In the navigation device 100 configured as described above, a user (corresponding to a user) operates the touch panel 21 and designates content information related to the content stored in the content database 40 (described later), thereby driving corresponding to the content. Navigation can be executed by specifying a destination based on history information. Details of the function will be described below with reference to FIGS.

  FIG. 2 is a functional block diagram showing a software configuration example of a navigation program that operates in the navigation device 100 shown in FIG. In FIG. 2, the navigation program functions as a guidance unit 31, a spot information acquisition unit 32, a route search unit 33, a search control unit 34, a travel history generation unit 35, a content playback unit 36, a content It has the selection part 37, the map database 38 which stored the said map data, the driving | running | working history database 39, and the content database 40 which stored the said content information. The navigation program causes the navigation device 100 to perform these functions and functions described later.

  The point information acquisition unit 32 (corresponding to the point information acquisition unit) acquires point information corresponding to the current location of the vehicle 1 (corresponding to the user's movement position) based on the detection result of the current location detection sensor 22.

  The travel history generating unit 35 (corresponding to the travel history generating unit) generates travel history information including at least the spot information acquired by the spot information acquiring unit 32 when the vehicle 1 travels (corresponding to the movement of the user). To do. The generated travel history information is stored in the travel history database 39.

  The route search unit 32 (corresponding to route search means) searches for a route from the current location detected by the current location detection unit 31 to the destination set by the user based on the map data in the map database 38.

  The guide unit 31 guides the vehicle 1 while superimposing the route from the current location searched for by the route search unit 32 to the destination on the map based on the map data acquired from the map database 38 and displaying the route on the display 15. . In addition, since the user guides the vehicle 1 on which the user is aboard, the guide unit 31 substantially functions as a guide unit that guides the user who is a user.

  The search control unit (corresponding to the first search control means) 34 controls the route search unit 32 to perform navigation when the user specifies the content information in the content database 40 by the touch panel 21 as described above. Set the destination. At that time, the search control unit 34 controls the route search unit 32 to set the destination using the travel history information associated with the content information designated by the user.

  FIG. 3 is an explanatory diagram showing an example of the data structure of the travel history information and the content information associated with each other.

  In FIG. 3A, the content information includes content data that is the main body of the content, for example, the song title, artist name, album name, song genre, movie title, director name, leading actor name, TV / radio It is a file composed of tag information (corresponding to content identification information) such as the program name, broadcast station, and broadcast time of the program. In the example shown in FIG. 3A, unlike the later-described FIGS. 3B and 3C, the travel history information is created as a dedicated management file different from the content information. In this management file, in addition to the travel history information such as the point information, at least a part of the corresponding tag information is stored. That is, in this example, at least a part of the tag information is shared by both files, thereby associating the content information with the travel history information. In the present embodiment, the content information and the travel history information in the form shown in FIG. 3A are stored in the content database 40 and the travel history information database 39, respectively.

  In addition to the above, the modes shown in FIGS. 3B and 3C are also conceivable. In the example shown in FIG. 3B, the travel history information is embedded in the content information file. As the embedded location, a location that does not depend on the file format of the content (for example, MP3 or AAC) is selected. As a result, the reproduction of the content file is not necessarily guaranteed except for a device that supports this function, but there is an advantage that individual processing depending on each file format is not necessary and processing can be shared. In this case, since the travel history information is integrated with the content information, the travel history database 39 is functionally integrated with the content database 40.

  In the example shown in FIG. 3C, the driving history information is embedded in the content information file, as in FIG. However, unlike the case of FIG. 3C, it is embedded as information in accordance with the file format of the content (MP3, AAC, etc.). By conforming to the file format, there is an advantage that even if the device does not have a function using the travel history information, it is guaranteed that the content data is normally reproduced. In this case as well, the traveling history database 39 is integrated with the content database 40 in terms of function.

  Returning to FIG. 2, the content selection unit 37 reads content data of content designated by the user from the content database 40 to the content reproduction unit 36 using the touch panel 21 or the like. The content playback unit 39 (corresponding to the content playback unit) plays back the content read by the content selection unit 37.

  The map data, the travel history information, and the content information constituting the map database 38, the travel history database 39, and the content database 40 are stored in the storage medium 16 as described above. It should be noted that at least one of the map database 38, the travel history database 39, and the content database 40 is configured in a server or the like outside the vehicle 11, and data is acquired or stored from these databases via wireless communication or the like. It may be.

  Next, an example of a navigation method performed by the navigation device 100 having the above-described configuration example will be described with reference to the flowchart of FIG. This navigation method is configured by each step executed by the navigation program in the CPU 7, and includes the following processing.

  In FIG. 4, first, in step S <b> 5, for example, a display prompting the user to select a mode is performed on the touch panel 21. That is, in the navigation apparatus 100 of this embodiment, as described above, navigation is performed from the travel history by designating content. The user then selects a mode for executing such a navigation mode (hereinafter referred to as “content navigation mode” as appropriate) and a mode for executing a normal navigation mode (hereinafter referred to as “normal mode” as appropriate), for example, a touch panel. 21 is selectable. In step S5, a display prompting which one of the two modes is selected is performed, and it is determined whether or not the content navigation mode is selected in step S10.

  If the user selects the normal mode, the determination in step S10 is not satisfied, and the routine goes to step S11. In step S11, it is determined whether or not the destination has been set by the touch panel 21 corresponding to the normal navigation function. If the user sets the destination, the determination is satisfied, and the routine goes to Step S147 described later, where a normal route search is executed. In the content navigation mode of the present embodiment, the travel history is accumulated as described above. However, if such history accumulation is performed all the time when the vehicle 1 is traveling, the amount of data becomes enormous. By selecting the normal mode for daily use, such a data amount problem can be avoided. Alternatively, the upper limit of the accumulated amount of travel history or the storage period is determined, and means for determining when the upper limit of the accumulated amount is exceeded or when the storage period is exceeded is provided, and the determination of this determination means is satisfied Sometimes, means for automatically erasing old data or means for transmitting old data to an external device such as a server may be provided.

  On the other hand, if the user selects the content navigation mode in step S10, the determination is satisfied, and the routine goes to step S13. In step S13, it is determined whether to reproduce the content. For example, a display asking whether to perform content reproduction may be displayed on the touch panel 21, and the user may perform a confirmation operation through an appropriate operation on the touch panel 21. When this confirmation operation is performed, the determination at Step S10 is satisfied, and the routine goes to Step S32. Alternatively, the determination in step S10 may be satisfied by operating a button on the touch panel 21 that shifts from a navigation function to a content reproduction function (so-called AV function). Alternatively, the determination in step S10 may be satisfied by operating a button that shifts from an initial screen (not shown) of the touch panel 21 to a content playback function (so-called AV function).

  In step S32, the content identification information written in the storage medium 16 is displayed as a list. Thereafter, the process proceeds to step S35, and it is determined whether or not content is selected on the touch panel 21 in the state where the list is displayed. When the user selects any content on the touch panel 21, the determination in step S35 is satisfied, and the process proceeds to step S40. If the user does not select content, the determination is not satisfied, and the routine goes to Step S55 described later.

  In step S40, the content data of the content selected by the user in step S35 is acquired from the content database 40, and the content is reproduced. Thereafter, the process proceeds to step S45.

  In step S45, as in step S12, the current location of the vehicle 1 is acquired as the point information based on the detection result of the current location detection sensor 22. Thereafter, the process proceeds to step S50.

  In step S50 (corresponding to the storage step), the point information acquired in step S45 is used as the travel history of the vehicle 1 for the content information (content data and content data identification information) reproduced in step S40. Correlate as information. This association is executed by, for example, any one of the methods shown in FIGS. Then, the associated content information and travel history information are stored in the travel history database 39 and the content data 40 (or any one of them), and the process proceeds to step S55.

  In step S55, it is determined whether or not the vehicle 1 has arrived at the destination. Specifically, it is sufficient to determine whether or not the engine of the vehicle 1 has stopped or whether or not the stop time of the vehicle 1 has exceeded a predetermined threshold value. In addition, when driving | running | working by guidance by navigation, you may determine by whether it reached | attained the destination set in navigation, but this case is mentioned later (refer modification (4)). Until the arrival at the destination, the determination in step S55 is not satisfied, and the process returns to step S32 and the same procedure is repeated. When the vehicle arrives at the destination, the determination in step S55 is satisfied, and the process returns to step S5.

  On the other hand, if the user does not perform an operation for reproducing the content in step S13, the determination is not satisfied, and the routine goes to step S105. In step S105, as in step S32, the content identification information written in the storage medium 16 is displayed as a list. Thereafter, the process proceeds to step S110, and similarly to step S35, it is determined whether or not content is selected on the touch panel 21 in a state where the list is displayed. Until the user selects any content on the touch panel 21, the determination in step S110 is not satisfied, and the process returns to step S105 and the same procedure is repeated. When the user selects any content on the touch panel 21, the determination in step S110 is satisfied, and the process proceeds to step S115.

  In step S115, whether the travel history information is associated with the content information of the content selected by the user in step S110 in the above-described steps S40 to S50 by the method described in FIGS. Whether or not is determined. If the travel history information is not associated with the content information, the determination in step S115 is not satisfied, and the process returns to step S5 after an appropriate error display is performed on the touch panel 21 by moving to step S120. If the travel history information is associated with the content information, the determination at Step S115 is satisfied, and the routine goes to Step S130.

  In step S130, according to the determination result in step S115, the content is reproduced using the travel history information associated with the content information of the content selected in step S110, that is, the point information in this example. The playback location is displayed on the touch panel 21 (see FIG. 5B described later).

  In step S135, it is determined whether or not a confirmation operation by the user has been performed on the playback location of the content displayed in step S130. When the user performs an appropriate confirmation operation using the touch panel 21, for example, the determination in step S135 is satisfied, and the process proceeds to step S147.

  In step S147, the current location of the vehicle 1 is acquired based on the detection result of the current location detection sensor 22. Thereafter, the process proceeds to step S150.

  In step S150, a route from the current location of the vehicle 1 acquired in step S147 to the destination is searched based on the map data. If the process proceeds from step S135 to step S147, the content playback location displayed in step S130 is automatically set as the destination (corresponding to the destination setting step). As a result, a route search from the current location of the vehicle 1 to the playback location of the content is executed (corresponding to a route search step). On the other hand, if the process proceeds from step S11 to step S147, a route search from the current location of the vehicle 1 to the destination set by the user in step S11 is executed. Thereafter, the process proceeds to step S155.

  In step S155, the route to the searched destination is displayed on the touch panel 21 based on the search result in step S150. Thereafter, the process proceeds to step S160.

  In step S160, it is determined whether or not an editing operation has been performed on the route displayed in step S155 by the user. For example, when the user performs editing operations such as destination correction, stop-by location setting, and alternative route request for the route using the touch panel 21, the determination in step S160 is satisfied, and the process returns to step S150. The route search corresponding to the editing operation is performed again. When the editing operation is not performed, the determination in step S160 is not satisfied, and the process proceeds to step S165.

  In connection with the editing operation, for example, in step S160, the content playback location itself is not automatically set as the destination, but an appropriate location within the predetermined range in the vicinity of the content playback location is set as the destination. You may make it set. That is, for example, landmarks, historic sites, restaurants, dealers, gas stations, parking lots, toll booths, intersections, interchanges, and other various facilities, buildings, and characteristic terrain within a predetermined range near the reclaimed land For example, a destination satisfying a predetermined condition (or satisfying a condition set by the user as appropriate) may be automatically set as the destination. Alternatively, destination candidates that satisfy such conditions may be displayed as a list, and may be set as a confirmed destination by the user performing a selection operation on the touch panel 21.

  Thereafter, in step S165, it is determined whether guidance can be started in the destination setting and route setting at this time. For example, when the user operates a guidance start button (see FIG. 5 (3) described later) with the touch panel 21, the determination in step S165 is satisfied, and the process proceeds to step S170 (corresponding to a guidance process) to start navigation. Until the guidance start button is operated, the determination in step S165 is not satisfied, and the process returns to step S155 to repeat the same procedure.

  FIGS. 5A to 5D are explanatory diagrams illustrating transition of the display screen on the touch panel 21 in the present embodiment. In this example, music is taken as an example of content. On the screen G1 shown in FIG. 5A, buttons “Song A”, “Song B”, “Song C”, and “Song D” corresponding to four songs included in the album “Album A” of an appropriate artist are displayed (FIG. 4). Step S105). In this screen G1, when the user operates the “SongA” button, the screen moves to the screen G2 in FIG. 5B and the playback point of the music is displayed (see step S130 in FIG. 4). In the example shown in the figure, “XX prefecture XX city △△ town XX address” is displayed as a button along the administrative division, but this is not a limitation, and other indications that can be recognized by the user (a mark or a guide) It may be a name display of various facilities / buildings / characteristic terrain, a longitude / latitude display, etc.) (see FIG. 5 (d) described later).

  When the user confirms the above-mentioned display contents on the screen G2 and operates the “XXX prefecture XX city ΔΔ town XX address” button, the screen shifts to the screen G3 in FIG. On the screen G3, a route search from the current location is performed with the displayed reproduction point as a destination (indicated by ♪ in the figure), and the search result is displayed on the map (step S155 in FIG. 4). reference). Then, when the user operates the “guidance start button” on the screen G3, guidance by the route is started (see step S165 and step S170 in FIG. 4). The screen G4 in FIG. 5D will be described later.

  The navigation method (corresponding to the guidance route search method) in the above embodiment is a navigation method used in the navigation device 100 (corresponding to the guidance route search device) that guides and guides the user (corresponding to the user) to the destination. The travel history information (corresponding to the travel history information) generated according to the travel of the vehicle 1 (corresponding to the movement of the user) and the content information related to the content reproduced when the vehicle 1 travels are associated with each other. Step S50 (corresponding to the storage step) and the operation for designating the content information stored in step S50, the travel history information associated with the designated content information is used. Step S150 for setting the destination (corresponding to the destination setting step) and step S150 A step S150 of searching for the route to a destination (equivalent to the route searching step), the.

  That is, when the vehicle 1 travels, travel history information is generated. When content such as a music, a movie, a movie, or a program is reproduced during the travel, content information such as content data or identification information of the content and the generated travel history information are mutually connected in step S50. Correspondingly stored. Thereafter, when the user designates the content stored in step S50, a destination for navigation is set in step S150 using the travel history information associated with the designated content information. Then, a route to the set destination is searched, and the vehicle 1 is guided in step S170 according to the searched route.

  In the navigation device 100 (corresponding to the guidance route searching device) in the above-described embodiment, the content reproduction unit 39 (corresponding to the content reproduction unit) that reproduces content and the travel history that generates travel history information when the vehicle 1 travels. A generation unit 35 (corresponding to a movement history generation unit), the travel history information generated by the travel history generation unit 35 when the content reproduction unit 39 reproduces the content, and content information related to the reproduced content Are stored in association with each other, a storage medium 16 (corresponding to the first storage means), a route search unit 32 (corresponding to the route search means) for searching for a route from the departure place to the destination, and a user (user) Corresponds to the touch panel 21 for performing an operation (hereinafter referred to as a specifying operation) for specifying the content. And the destination information is set using the travel history information associated with the designated content information when the operation for designating the content information stored in the storage medium 16 is performed on the touch panel 21. The search controller 34 (corresponding to the first search control means) that controls the route search unit 32 so as to search for the route to the set destination, and the destination searched by the route search unit 32 And a guiding unit 31 (corresponding to guiding means) for guiding the vehicle 1 (corresponding to guiding the user) according to the route up to.

  That is, when the vehicle 1 travels, travel history information is generated by the travel history generation unit 35. When content such as a song, a movie, a movie, or a program is reproduced by the content reproduction unit 39 during the travel, the storage medium 16 is generated with content information such as content data and identification information of the content, for example, The travel history information is stored in association with each other. Thereafter, when the user specifies content information stored in the storage medium 16 using the touch panel 21, the route search unit 32 is associated with the specified content information based on the control of the search control unit 34. The destination is set using the travel history information, and the route to the set destination is searched. Then, the guiding unit 31 guides the vehicle 1 according to the searched route.

  As described above, when the user wants to go again to a specific place related to the travel history when the vehicle 1 has traveled in the past, even if the exact position or name of the place is not known, The vehicle 1 can be smoothly guided to the place simply by remembering and specifying the content that was being played. In particular, in general, a voice memory recognized by auditory sense has a stronger impression and is superior in sustainability and accuracy than a memory of text / image information recognized visually. Therefore, even if the user does not clearly remember the scenery, the location of the building, the name of the store, etc. that were viewed casually while the vehicle was running, the audio contained in the content being played at that time is in the user's head. There is a high possibility that it remains clearly. As a result, according to the present embodiment, the user can surely revisit the place as described above, which has been difficult to visit once again, and the convenience can be improved.

  There is also another effect. That is, when the user tries to drive, the destination corresponding to the content is automatically set only by specifying the appropriate content that has been conceived. The screen G4 in FIG. 5 (d) shows such an example of use. When the user operates the “SongB” button on the screen G1 in FIG. 5 (a), the screen G4 in FIG. 5 (d) is displayed. , “The vicinity of the XX valley Δ △ bridge”, which is the playback point of the music, is displayed. As a result, this XX valley can be automatically set as the navigation destination, so that the user can save time and effort to select the destination by operating the touch panel 21 in various ways. This effect of reducing the operation burden can be obtained even when the user has memorized the location of the destination. That is, even if the user remembers that he / she went to the XX valley, the effect of reducing the operation burden can be obtained. As a result, the user can easily enjoy driving without having to think deeply about where to go, so convenience in this sense can also be improved.

  As described above, in this embodiment, user convenience can be improved by a new method of setting a navigation destination by designating content.

  In the navigation device 100 in the above embodiment, in addition to the above-described configuration, the spot information acquisition unit 32 (spot information acquisition means) that acquires spot information corresponding to the travel position of the vehicle 1 (corresponding to the user's travel time). The travel history generation unit 35 generates the travel history information including the spot information acquired by the spot information acquisition unit 32 when the vehicle 1 travels, and the storage medium 16 When the content is reproduced by the content reproduction unit 36, at least one piece of the spot information generated by the travel history generation unit 35 is stored in association with the content information, and the search control unit 34 is specified. A destination is set using the at least one point information included in the travel history information associated with the content information, To perform a search of the constant route to the destination, and controls the route search unit 33.

  If it does in this way, the destination will be set using the point information of the place where the vehicle 1 has traveled in the past. Then, by guiding the destination, the user can surely revisit a place that was difficult to revisit in the past.

  In the navigation device 100 in the embodiment, in addition to the above-described configuration, the search control unit 34 sets any one of the at least one point information included in the travel history information as a destination, and the setting. The route search unit 33 is controlled to search for a route to the destination.

  In this way, the user can reliably revisit the place where the vehicle 1 was traveling when the content was reproduced in the past.

(1) When there are a plurality of playback locations In the above-described embodiment, the case where one piece of point information is associated with one piece of content has been described as an example. However, the present invention is not limited to this. That is, when a plurality of pieces of point information are associated with one content, the user may select one of them.

  FIG. 6 shows a control procedure related to the navigation method executed in this modification. In the flowchart of FIG. 6, steps S125, S140, and S145 are newly added to the flowchart of FIG. 4 of the above embodiment. That is, when the travel history information is associated with the content information, the determination at step S115 is satisfied, and the process proceeds to the newly provided step S125.

  In step S125, it is determined whether or not there is a plurality of the travel history information (point information in this example) associated with the content information of the content selected by the user in step S110. If there are a plurality of points where the content has been reproduced in the past and a plurality of pieces of traveling history information are associated with the content information, the determination in step S125 is satisfied, and the process proceeds to step S140.

  In step S140, in accordance with the determination result in step S125, a plurality of reproduction locations where the content is reproduced using a plurality of pieces of point information associated with the content information of the content selected in step S110. A list is displayed on the touch panel 21 (see FIG. 7B and FIG. 7C described later). This prompts the user to select one of the plurality of playback locations.

  In step S145, it is determined whether or not a selection operation by the user has been performed on any one of a plurality of content playback locations displayed in the list in step S140. For example, when the user performs an operation of selecting one appropriate playback location using the touch panel 21, the determination in step S145 is satisfied, and the process proceeds to step S147 described above.

  On the other hand, in step S125, when there is only one point where the content has been reproduced in the past and only one traveling history information is associated with the content information, the determination in step S125 is not satisfied, and the same as in the above embodiment. After step S130 and step S135, the process proceeds to step S147.

  Since the procedure other than the above is the same as that of the above embodiment, the description is omitted.

  FIGS. 7A to 7E are explanatory diagrams showing the transition of the display screen on the touch panel 21 in this modification. This example also uses music as an example of content, as described above. In FIG. 7A, as in FIG. 5A of the above embodiment, on the screen G1, the buttons “Song A”, “Song B”, “Song C” corresponding to the four songs included in the album “Album A” of the appropriate artist are displayed. "SongD" is displayed. In this screen G1, when the user operates the “SongA” button, the screen moves to screen G5 in FIG. 7B. In this example, a plurality of (three in this example) playback points where the music is played back are Each is displayed as a button (see step S140 in FIG. 6). In this example, three of “XX prefecture XX city △ Δ town XX address”, “XX prefecture XX city XX neighborhood”, and “XX prefecture XX town △ Δ intersection” are displayed. At this time, when the user performs an appropriate operation on the touch panel 21, the screen shifts to a screen G6 shown in FIG. 7B (or may be automatically switched over time). On the screen G6, the three playback locations are displayed as marks “S1 ♪”, “S2 ♪”, and “S3 ♪” on the map.

  When the user confirms the above-mentioned display content on the screen G6 and operates the “S3 ♪” mark with the intention of selecting the reproduction place “near the XX prefecture ×× town Δ △ intersection”, FIG. Move to screen G7. On the screen G7, a route search from the present location is performed with the selected reproduction point, that is, “Near XX prefecture ×× town Δ △ intersection” of the “S3 ♪” mark, and the search result is displayed on the map. Is displayed (see step S155 in FIG. 6). Then, when the user operates the “guidance start button” on the screen G7, guidance by the route is started (see step S165 and step S170 in FIG. 6). The screen G8 in FIG. 7D will be described later.

  In the navigation device 100 according to the modified example, in addition to the above-described configuration, the storage medium 16 further includes a plurality of pieces generated by the travel history generation unit 35 when the content reproduction unit 36 reproduces the content. A touch panel 21 (corresponding to position display means) is provided that stores the spot information in association with the content information and displays a list of the spot information stored in the storage medium 16 so that the user can select it. The search control unit 34 sets a destination using the point information selected by the user among the plurality of point information displayed in a list on the touch panel 21 and searches for a route to the set destination. The route search unit 33 is controlled to perform this.

  That is, when a user reproduces content, the reproduction is often performed not only once but multiple times. In this modification, corresponding to this, a plurality of pieces of point information (for example, pieces of point information that are different from one another) that the vehicle 1 was traveling at each of the plurality of times of reproduction are stored in the storage medium 16 (steps). (See S50). Then, the touch panel 21 displays a list of the plurality of pieces of point information by the user's operation (see step S140 and screens G5 and G6), so that the user can surely find a place according to his / her intention from the list display. It can be found and selected (see step S145). Thereby, since the place which a user intends can be set as a destination reliably from a plurality of destination candidates, the user can surely revisit the place as in the above embodiment.

  In addition, the present modification also has an effect different from the above as in the above embodiment. In other words, when a user tries to drive, simply specifying an appropriate content that has been conceived, the destination candidates corresponding to the content are automatically displayed in a list. The screen G8 in FIG. 7 (e) shows such an example of use. When the user operates the “SongB” button on the screen G1 in FIG. 8 (a), the screen G8 in FIG. 8 (e) is displayed. , “XX valley Δ △ bridge vicinity”, “xx amusement park”, and “ΔΔ mountain 8th parking lot”, which are a plurality of reproduction points of the music, are displayed. As a result, the navigation destination can be automatically set by simply selecting one desired location from these, so that the user can save the trouble of selecting the destination by performing various operations on the touch panel 21. As a result, as described above, the user can easily enjoy driving without having to think deeply about where the destination is, so convenience can be improved in this sense.

  In this modification, there is another way for the user to enjoy. That is, as described above, a plurality of disjoint pieces of spot information that the vehicle 1 was traveling at each of a plurality of times of reproduction are displayed in a list by the user's operation, and the user reproduces the content by viewing the list display. You can remember the places and memories you visited. Moreover, the contents displayed in the list can be a topic when there are passengers, and the enjoyment and satisfaction in the vehicle increases. This effect can also be obtained even when the user stores the list-displayed location, as described above.

  As another case, for example, even when playing back one piece of content, if the playback time is relatively long, a plurality of pieces of point information may be acquired during playback. Is stored in the storage medium 16. FIG. 8A shows the transition of the display screen on the touch panel 21 in such an example. In FIG. 8A, as in FIG. 7A, the buttons “Song A”, “Song B”, “Song C”, and “Song D” corresponding to the four songs included in the album “Album A” of the appropriate artist are displayed on the screen G1. Is displayed. In this screen G1, when the user operates the “SongC” button, the screen moves to screen G9 in FIG. 8B, and in this example, a plurality of (three in this example) playback points where the music is played back are Each is displayed as a button (see step S140 in FIG. 6). In this example, three areas are displayed, “near the XX toll road XX lamp”, “xxx toll road △△ near the lamp”, and “xxx toll road xx near the lamp”. In other words, in this case, one piece of music is played while running on the XX toll road, and three pieces of lamps are passed while the piece of music is being played, and point information is acquired in each of them. At this time, when the user performs an appropriate operation on the touch panel 21, the screen moves to a screen G10 shown in FIG. 8C (or may be automatically switched over time).

  On the screen G10, the three playback locations are displayed on the map as marks “S1 ♪”, “S2 ♪”, and “S3 ♪”, respectively, in a straight line along the traveling direction. Therefore, the user can display the list according to whether the portion remaining in his / her head in correspondence with the place he / she wants to visit is the first half, the second half, or the middle of the music. You can reliably find and select a place that will meet your intentions. In the example shown in the figure, the user operates the “S3 ♪” mark on the screen G10 based on the memory that the place he / she wants to find is the latter half of the music piece, and as a result, the result shown in FIG. Moved to screen G11. As a result, the destination is set to the point information corresponding to the selected “S3 ♪” mark, that is, “XX toll road XX near the ramp”, and guidance is performed. As a result, the user can surely revisit a place where revisiting was difficult in the past.

  In the navigation device 100 according to the modified example, in addition to the above-described configuration, the search control unit 34 sets the point information selected by the user as a destination, and searches for a route to the set destination. The route search unit 33 is controlled to perform the following.

  As a result, the location selected by the user from among a plurality of destination candidates is set as the destination, so that the intention of the user among the plurality of locations where the vehicle 1 was traveling when the content was reproduced in the past. The user can reliably revisit the place to do.

(3) When using route information In the above, the spot information acquired based on the detection result of the current location detection sensor 22 is used as the travel history information, but the present invention is not limited to this. That is, route information may be generated using a plurality of pieces of point information, and the route information may be associated with content information as travel history information and used.

  FIG. 6 shows a control procedure related to the navigation method executed in this modification. In the flowchart of FIG. 9, steps S50A and S130A are newly provided in place of steps S50 and S130 in the flowchart of FIG. 4 of the above embodiment. That is, in step S50A, route information based on the spot information acquired in step S45 is generated, and the route information is associated with content information as travel history information of the vehicle 1. As the route information used at that time, based on the point information acquired in step S45, for example, route information may be generated based on a route name or the like predetermined for the point. Point information may be acquired and route information including the plurality of points may be generated. Further, the association between the route information and the content information is performed by, for example, any one of the methods shown in FIGS. Then, the associated content information and travel history information (route information) are stored in the travel history database 39 and the content data 40 (or any one of them), and the process proceeds to step S55.

  In step S115, when the travel history information (route information) is associated with the content information and the determination is satisfied, the process proceeds to step S130A. In step S130A, according to the determination result in step S115, the content is reproduced using the travel history information associated with the content information of the content selected in step S110, that is, the route information in this example. The playback path is displayed on the touch panel 21 together with the playback location (see FIG. 10B described later).

  Thereafter, when the user performs the confirmation operation, the process proceeds to step S147 through step S135. After the current location of the vehicle 1 is acquired, the process proceeds to step S150. In step S150, the reproduction destination included in the reproduction path of the content displayed in step S130A is automatically set as the destination. As a result, a route search from the current location of the vehicle 1 to the playback location of the content is executed (see FIG. 10C described later).

  Since the procedure other than the above is the same as that of the above embodiment, the description is omitted.

  FIGS. 10A to 10E are explanatory diagrams showing transition of the display screen on the touch panel 21 in the present modification. When the user operates the “SongA” button on the screen G1 in FIG. 10A, the screen shifts to the screen G12 in FIG. In this example, a route including a playback point (represented by a “♪” mark) where the music is played is displayed on the map as a straight line.

  When the user confirms the above-mentioned display contents on the screen G12 and operates the “♪” mark to select the playback location on the displayed route, the screen moves to the screen G13 in FIG. On the screen G13, a route search from the present location is performed with the selected reproduction point, that is, the “♪” mark as the destination, and the search result is displayed on the map (see step S155 in FIG. 9). Then, when the user operates the “guidance start button” on the screen G13, guidance by the route is started (see step S165 and step S170 in FIG. 9).

  In addition to the above-described configuration, the navigation device 100 according to the modification further includes a spot information acquisition unit 32 that acquires spot information corresponding to the travel position of the vehicle 1 (corresponding to the user's travel time), The travel history generation unit 35 generates the travel history information including route information based on the spot information acquired by the spot information acquisition unit 32 when the vehicle 1 is traveling (corresponding to a user's movement), and the storage The medium 16 stores at least one route information generated by the travel history generation unit 35 when the content is reproduced by the content reproduction unit 36 in association with the content information, and the search control unit 34 Uses the at least one route information included in the travel history information associated with the designated content information to determine a destination. Constant, and to perform a search for a route to the destination that the set, controls the route search unit 33.

  In this modification, a destination is set using route information that the vehicle 1 has traveled in the past. Then, by guiding the destination, the user can surely revisit a place where it was difficult to revisit in the past, as in the above-described embodiment and the modified examples of (1) and (2). . At this time, as described above, an appropriate location within the predetermined range in the vicinity of the content playback location may be set as the destination. Further, a predetermined location on both sides of the route included in the route information, a starting point or an ending point of the route, or an extension line of the route may be set as the destination.

  Further, this modification also has another effect. That is, when a plurality of contents are reproduced when the vehicle 1 travels along one route, a plurality of pieces of content information can be associated with one route information generated during the travel (step S50A). reference). In this case, when one piece of route information that has traveled in the past for destination setting is used according to one piece of content information designated by the user, other content information associated with the route information is stored in the storage medium 16. It can also be acquired from the content database 40. In that case, when the vehicle 1 travels by setting the destination using the route information, the content information specified by the user is displayed together with the content information specified by the user as a so-called playlist, or specified by the user. The other content can be reproduced together with the content. In other words, it is possible to reproduce and display a play list of a plurality of contents reproduced at the time of generation of a past travel history, and to replay a plurality of contents of the play list.

  Also in this modification, a plurality of route information can be associated with one content and used as travel history information as in the modification (1). In the navigation device 100 in that case, in addition to the above-described configuration, the search control unit 34 further sets the point information included in any of the at least one route information included in the travel history information as a destination. The route search unit 33 is controlled to search for a route to the set destination.

  In this way, the user can reliably revisit the place where the vehicle was traveling, which is included in the route that the vehicle 1 was traveling when the content was reproduced in the past.

  In the navigation device 100, in addition to the above-described configuration, the storage medium 16 further includes a plurality of the routes generated by the travel history generation unit 35 when the content reproduction unit 36 reproduces the content. Information is stored in association with the content information, and a touch panel 21 (corresponding to route display means) is provided for displaying a list of the plurality of route information stored in the storage medium 16 so that a user can select the information. The search control unit 34 sets a destination using the route information selected by the user among the plurality of route information displayed as a list on the touch panel 21 and searches for a route to the set destination. The route search unit 33 is controlled.

  In this way, the user can surely find and select a route according to his / her intention from the list display. Thereby, a place included in the route intended by the user can be reliably set as the destination from among a plurality of destination candidates, and the user can surely revisit the place. Further, as described above, since different route information on which the vehicle 1 was traveling at each time of a plurality of reproductions is displayed in a list by the user's operation, the user travels while viewing the list display and reproducing the content. You can remember the places and memories you have visited.

(4) When using a travel history at the time of past navigation travel In other words, when using travel history information at the time of travel using the navigation function, the display of the playback location of the content is displayed for the search route at the time of the past navigation. You may make it carry out with a display.

  FIG. 6 shows a control procedure related to the navigation method executed in this modification. In the flowchart of FIG. 6, Step S15, Step S20, Step S25, and Step S30 are newly added to the flowchart of FIG. 6 of the modified example (1). Further, step S55A is provided instead of step S55, and step S50 is added. Furthermore, instead of step S130 and step S140, step S130B and step S140B are provided.

  That is, when the content reproduction confirmation operation is performed and the determination in step S13 is satisfied, the process proceeds to newly provided step S15.

  In step S15, as in step S11, it is determined whether or not the destination is set by the touch panel 21. If the user performs destination setting, the determination is satisfied, and the routine goes to Step S20.

  In step S20, the current location of the vehicle 1 is acquired based on the detection result of the current location detection sensor 22, as in step S147. Thereafter, the process proceeds to step S25.

  In step S25, a route from the current location of the vehicle 1 acquired in step S20 to the destination set by the user in step S15 is searched based on the map data. Then, it moves to step S30 and navigation is started.

  After step S30, step S32, step S35, step S40, step S45, and step S50 are the same as described above, and a description thereof is omitted. When step S50 ends, the process proceeds to newly provided step S55A.

  In step S55A, it is determined whether or not the vehicle 1 has arrived at the navigation destination (in other words, the destination input in step S15) searched in step S25. Until the destination is reached, the determination in step S55A is not satisfied, and the process returns to step S32 and the same procedure is repeated. When the vehicle arrives at the destination, the determination at Step S55A is satisfied, and the routine goes to Step S60. In step S60, the route guidance started in step S30 is terminated, and the process returns to step S5.

  On the other hand, in step S125, it is determined whether or not there are a plurality of pieces of travel history information (point information in this example) associated with the content information, as in the modified example (1). If there are more than one, the determination in step S125 is satisfied, and the flow proceeds to newly provided step S140B.

  In step S140B, a plurality of the above-mentioned navigation times each including a reproduction place where the content is reproduced one by one using a plurality of pieces of point information associated with the content information of the content selected in step S110. Are displayed in a list on the touch panel 21 (see FIG. 12B described later). This prompts the user to select one of the plurality of playback locations. The subsequent steps S145 and thereafter are the same as described above.

  On the other hand, if there is only one piece of point information in step S125, the determination is not satisfied and the process proceeds to newly provided step S130B. In step S130B, using the single point information associated with the content information of the content selected in step S110, one search route at the time of the navigation including the one reproduction place where the content is reproduced is obtained. Is displayed on the touch panel 21. The subsequent steps S135 and thereafter are the same as described above.

  FIGS. 12A to 12E are explanatory diagrams showing transition of the display screen on the touch panel 21 in the present modification. When the user operates the “SongA” button on the same screen G1 as described above shown in FIG. 12A, the screen shifts to the screen G14 in FIG.

  On the screen G14, a plurality of (three in this example) reproduction points when the music is reproduced are displayed as search routes for guidance when traveling through the reproduction points (step S25 in FIG. 11). , (See step S30), and each is displayed as a “♪” mark (see step S140B in FIG. 11). That is, in this example, the reproduction place on the G1 route from the departure place “START” to the arrival place (= the destination at the time of guided movement, the same applies hereinafter) “G1”, and the departure place “START” to the arrival place “G2”. Three playback locations are displayed: a playback location on the G2 route up to and a playback location on the G3 route from the start location “START” to the arrival location “G3”.

  When the user confirms the display content on the screen G14 and operates an appropriate point on the G2 route with the intention of selecting the playback location on the G2 route, the screen shifts to the screen G15 in FIG.

  On the screen G15, the departure point of the G2 route, the arrival point (= the destination at the time of guided movement), and the reproduction point where the music is reproduced are displayed. In this example, it is displayed that the music has been played in the vicinity of “XX street XX intersection” on the route on the route starting from “Home” and arriving at “XX Amusement Park”. . Thereafter, when the user performs an appropriate operation on the touch panel 21, the screen shifts to a screen G16 shown in FIG. 12 (d) (or may be automatically switched over time).

  On the screen G16, a route search from the present location is performed with “XX street XX near the intersection” corresponding to the reproduction point on the selected G2 route, that is, the “♪” mark, and the search result is a map. It is displayed above (see step S155 in FIG. 11). Then, when the user operates the “guidance start button” on the screen G16, guidance by the route is started (see step S165 and step S170 in FIG. 11).

  In the navigation apparatus 100 according to the present modification, in addition to the above-described configuration, the travel history generation unit 35 is guided by the guidance unit according to the route searched by the route search unit 33 (corresponding to movement). ) (Hereinafter referred to as “guided movement”), the travel history information is generated, and the search control unit 34 uses the travel history information generated by the travel history generation unit 35 during the guided movement. The route search unit 33 is controlled to set a destination and to search for a route to the set destination.

  In the present modification, the user first causes the vehicle 1 to travel according to the guidance of the guidance unit 31 by the route searched by the route search unit 33 (see step S30 in FIG. 11). Then, travel history information is generated by the travel history generation unit 35 during the guided movement (see step S50 in FIG. 11). Then, the storage medium 16 stores the content information reproduced by the content reproduction unit 36 during the guided movement and the travel history information in association with each other (see step S50 in FIG. 11). Thereafter, the user designates the stored content information using the touch panel 21 (see step S110 in FIG. 11), so that the route search unit 33 is designated based on the control of the search control unit 34. A destination is set using the travel history information associated with the content information, and a route to the destination is searched (see step S150 in FIG. 11). And the guidance part 31 guides the vehicle 1 according to the searched path | route (refer step S170 of FIG. 11).

  Usually, the user travels the vehicle 1 by the guidance of the guidance unit 31 when the traveling place is a land that is unknown or unfamiliar to the user and the user is not familiar with the nearby geography. There are many. In this case, there is a particularly high possibility that the user does not remember (or cannot remember) the scenery, the location of the building, the name of the store, and the like as described above. Accordingly, in response to this, in the present modification, the storage medium 16 stores content information in association with the travel history information during the guided movement. As a result, the user can surely revisit a place that has been very likely to be difficult to revisit. At that time, as described above, an appropriate location within the predetermined range in the vicinity of the content playback location may be set as the destination. In addition, as in the modification (3) above, a predetermined neighborhood range on both sides of the searched route (G2 route in the above example), a destination, an arrival point, a stopover point, and an appropriate place on an extension line of the route May be set as the destination.

  Although the above modification has been described by taking as an example the case where one piece of content information is associated with one piece of content as travel history information, the present invention is not limited to this, and the modification of (3) above. As described above, one or a plurality of route information may be associated with each other.

(5) When using navigation history during past navigation travel In the modified example of (4) above, navigation is performed based on the specification of subsequent content using actual travel history information during past navigation travel. It was. However, at the time of guided movement in which navigation is performed, the actually traveled points and routes are completely the same as or almost the same as the points and routes searched by the navigation function. Therefore, instead of the travel history information, search history information including the searched search route or a point on the way may be used.

  FIG. 13 is a functional block diagram illustrating a software configuration example of a navigation program that operates in the navigation device 100 of the present modification. 13, in this modification, a search history generation unit 41 is provided instead of the travel history generation unit 35 in the function shown in FIG. 2, and a search history database 42 is provided instead of the travel history database 39. . Further, a search control unit 34 (corresponding to the second search control means) similar to FIG. 2 is provided.

  The search history generation unit 41 (corresponding to search history generation means) generates search history information including route information, departure point information, and destination information searched by the search control unit 34 when the vehicle 1 travels. The generated search history information is stored in the search history database 42 of the storage medium 16 (corresponding to the second storage means).

  FIG. 14 shows a control procedure related to the navigation method executed by the navigation device 100 of the present modification. In the flowchart of FIG. 14, steps S50A and S115A are provided in place of steps S50 and S115 in the flowchart of FIG. 4 of the above embodiment.

  That is, when the acquisition of the current location of the vehicle 1 is completed in step S45, the process proceeds to newly provided step S50A. In step S50A, for the content information (content data and content data identification information) reproduced in step S40, the route, departure point, destination, etc. acquired from the search result in step S25 are changed to the vehicle. 1 is associated as search history information. This association can be executed, for example, by any method in which “travel history information” is replaced with “search history information” in FIGS. Then, the associated content information and search history information are stored in the search history database 42 and the content data 40 (or any one of them), and the process proceeds to step S55A. The same applies thereafter.

  If the user selects any content on the touch panel 21, the determination in step S110 is satisfied, and the process proceeds to newly provided step S115A. In step S115A, whether the search history information is associated with the content information of the content selected by the user in step S110 by the method described in FIGS. 3A to 3C in steps S40 to S50A described above. Whether or not is determined. If the search history information is not associated with the content information, the determination in step S115A is not satisfied, the process proceeds to step S120, an appropriate error display is performed on the touch panel 21, and the process returns to step S5. If the search history information is associated with the content information, the determination at Step S115A is satisfied, and the routine goes to Step S125. The same applies thereafter.

  The procedures other than those described above may be applied by replacing “travel history information” in each procedure shown in FIG. 11 with “search history information”, and thus detailed description thereof is omitted.

  The navigation device 100 according to the present modification includes a route search unit 33 that searches for a route from a departure point to a destination, and guides the vehicle 1 according to the route to the destination searched by the route search unit 33 (the user's A navigation device having a guidance unit 31 (corresponding to guidance), the content reproduction unit 36 for reproducing the content, and the route search unit 33 when the vehicle 1 travels (corresponds to the movement of the user). A search history generation unit 41 (corresponding to a search history generation unit) that generates search history information including searched route information, departure point information, and destination information, and the search history when the content reproduction unit 36 reproduces the content. A storage for storing the search history information generated by the generation unit 41 and the content information related to the reproduced content in association with each other A body 16 (corresponding to the second storage means), a touch panel 21 for a user (corresponding to the user) to specify the content, and the content information stored in the storage medium 16 in the touch panel 21 When a designation operation is performed, a destination is set using at least one of the route information, the departure point information, and the destination information included in the search history information associated with the designated content information And a search control unit 34 (corresponding to second search control means) for controlling the route search unit 33 so as to search for a route to the set destination.

  In the navigation device 100 according to the present modification, the user first causes the vehicle 1 to travel according to the guidance of the guidance unit 31 by the route searched by the route search unit 33. During this guided movement, the search history generation unit 41 generates search history information (including route information, departure point information, destination information, etc.). When the content reproduction unit 36 reproduces content such as a song, a movie, a movie, or a program during this guided movement, the storage medium 16 generates content information such as content data or identification information of the content, and the like. The search history information is stored in association with each other (see step S50A in FIG. 14). Thereafter, when the user specifies content information stored in the storage medium 16 using the touch panel 21, the route search unit 33 is associated with the specified content information based on the control of the search control unit 34. The destination is set using the search history information, and the route to the set destination is searched (see step S150 in FIG. 14). Then, the guiding unit 31 guides the vehicle 1 according to the searched route (see step S170).

  Thereby, when the user wants to go again to a specific place related to the search history when the vehicle 1 has traveled in the past while guiding the guide unit 31, the exact position and name of the place are known. Even if it is not, the vehicle 1 can be smoothly guided to the place again simply by remembering and specifying the content being played back at that time. In particular, in general, a voice memory recognized by auditory sense has a stronger impression and is superior in sustainability and accuracy than a memory of text / image information recognized visually. Therefore, even if the user does not clearly remember the scenery, the location of the building, the name of the store, etc. that were viewed casually while the vehicle was running, the audio contained in the content being played at that time is in the user's head. There is a high possibility that it remains clearly. As a result, according to this modification, the user can surely revisit the place as described above, which has been difficult to visit once again, and convenience can be improved.

  In particular, the user travels the vehicle 1 by the guidance of the guidance unit 31 when the traveling place is an unknown land or an unguided land for the user and the user is not familiar with the nearby geography. There are many. In this case, there is a particularly high possibility that the user does not remember (or cannot remember) the scenery, the location of the building, the name of the store, and the like as described above. In this modified example, as a result of the storage medium 16 storing the content information in association with the search history information at the time of the guided movement, the user can surely go to a place where the possibility of revisiting was very high in the past. Can revisit.

  Note that the above is an appropriate user from the initial screen (not shown) of the content playback function (so-called AV function) provided in the navigation device 100 as shown in FIGS. The case where the screen G1 is displayed based on the above-described operation and the screen G1 is further displayed by the appropriate user operation in the state in which the screen G1 is displayed has been described as an example, but is not limited thereto. . That is, the screen G1 or a screen equivalent thereto is displayed by an appropriate button or the like provided on the navigation function screen provided in the navigation device 100, and further by an appropriate user operation while the screen G1 is displayed. You may make it transfer to each screen G2-G16 after that.
