Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an in-vehicle navigation device, and in particular, adds a location (POI) for providing advertisement information related to content including POI (Point of Interest) information when providing route guidance to a destination. In this case, the present invention relates to an in-vehicle navigation device adapted to automatically register the POI in the most efficient order.
[0002]
[Prior art]
In a typical vehicle-mounted navigation device that is generally known, a CPU that controls all processes related to navigation, a storage device such as a CD-ROM or a DVD-ROM that stores map data, a display device, and a current device of the vehicle. A GPS (Global Positioning System) for detecting a position, a gyro and a vehicle speed sensor for detecting a traveling direction and a traveling speed of the own vehicle, and a VICS (Vehicle Information and Communication) for receiving traffic information. System) A receiver and the like are provided. The CPU reads out the map data including the current position of the vehicle from the storage device, draws a map image around the position of the vehicle on the display screen based on the map data, and indicates the current position of the vehicle. The vehicle position mark is superimposed and displayed on the display screen, the map image is scrolled according to the movement of the vehicle, or the vehicle position mark is moved while the map image is fixed on the screen. At a glance where they are currently driving.
[0003]
In addition, the in-vehicle navigation device is usually provided with a function (route guidance function) for guiding a user to easily travel on a road to a destination without making a mistake. According to the route guidance function, the CPU calculates the optimal route from the starting point (typically, the current position of the vehicle) to the destination using the map data by simulation such as a horizontal search method or a Dijkstra method. Is performed, and the searched route is stored as a guide route, and the guide route can be distinguished from other roads on the map image during traveling (for example, by changing the color or increasing the line width). Display), and when the vehicle approaches the intersection to change course on the guidance route within a predetermined distance, an enlarged view of the intersection is displayed on the map image, so that the destination can be displayed. The user can grasp the optimal route for the route.
[0004]
In a conventional in-vehicle navigation device, an optimal guidance route determined based on the above route search is displayed on a map screen of a display, and various facilities and properties (convenience stores) existing around the guidance route are marked. , Gas stations, super discount shops, etc.) are displayed on the map screen. Then, when the route is guided to the destination, the user can easily check the route by using the POI information as a mark. Such POI information is basically included in a map database mounted on a vehicle, but can also be obtained from outside via the Internet or the like.
[0005]
On the other hand, in recent years, services for distributing information of various contents via the Internet have been provided on many websites, and push-type distribution has been increasing as a method of distributing the contents. This is a form in which content is unilaterally distributed from a service provider (also simply referred to as a “server”) to a terminal (a personal computer, a PDA, a mobile phone, or the like). Specifically, a so-called hot spot is used. This is a form of distributing information limited to an area, and distributes special sale information of a shop, time service information, coupons, and the like to terminals that can communicate in a specific area at once. For example, when a shop (various facilities or properties) that wants to provide advertisement information requests a nearby push-type distribution service company (server) and designates a region (a plurality of regions) to distribute, the hotspot of each region is designated. The content including the advertisement information is distributed from the spot, and the advertisement information is provided to all terminals within the area at that time. When the push-type content is distributed from the server to the terminal, the content is usually immediately displayed on a screen such as a monitor.
[0006]
Such push-type content includes, in addition to the original advertisement information, information (POI information) indicating the location of a facility or property that provides the advertisement information, and further includes advertisement information related to the time service. In the case of (1), information (hereinafter, referred to as “time information”) specified about a time zone, a period, a date, and the like in which the service related to the advertisement information can be enjoyed is also included. Therefore, the terminal (in-vehicle navigation device) obtains the POI information included in the push-type content via the Internet and adds the POI information to the route guidance on the map screen, thereby confirming the guidance route to the destination. Easier to do.
[0007]
In the related art, when POI information is added to route guidance via a plurality of passing points (stop points) to a destination (destination), the POI information is included in an on-vehicle map database. Whether or not it is included in the push-type content distributed via the Internet, the user decides on the basis of the guidance order of each guide destination (passing point, destination, POI). The determined contents are input by operating a remote control transmitter or the like and registered in an internal memory or the like, and the CPU performs necessary route search and route guidance based on the registered contents.
[0008]
As a technology related to the above-described conventional technology, for example, there is a technology in which a new destination can be added after the guidance of a guidance route to an initially set destination is started (for example, Patent Document 1). reference). In addition, in performing an automatic route search, there is a configuration in which, when there are a plurality of passing points that pass through to a destination, the order of those passing points can be changed according to the user's intention (for example, Patent Document 2). reference).

[Problems to be solved by the invention]
As described above, in the conventional technology, when adding POI information to route guidance, the user considers the guidance order (the order of POIs on the guidance route) and operates a remote control transmitter or the like to register the information in the device. Therefore, there is a problem that the operation is troublesome, a considerable time is required for the operation, and the convenience for the user is poor.
[0011]
In the case of push-type content including POI information, if there is distribution from the server as described above, the content is immediately displayed on a screen of a monitor or the like. If you pay close attention to the contents, there is a problem in terms of safety. Therefore, when the push-type content is distributed, the content is temporarily stored in an internal memory or the like, and based on the operation of the remote control transmitter or the like as described above when the vehicle is stopped such as waiting for a signal. It is assumed that POI registration is performed. In this case, since the vehicle cannot stay at the place forever, it is desirable that the POI be automatically registered without taking time.
[0012]
Furthermore, even if POI registration is performed automatically, a simple method such as registration at the beginning or end may take a detour to get to the original destination, or may be a push type content including time information. In such a case, there is an inconvenience that the time of the time service is not taken into account (that is, there is a possibility that the user cannot arrive in time to provide the advertisement information related to the content).
[0013]
The present invention has been created in view of the problems in the related art, and when adding POI information to route guidance, it is possible to automatically register the POI information in the most efficient order, and as a result, An object of the present invention is to provide an in-vehicle navigation device that can improve convenience.
[0014]
[Means for Solving the Problems]
In order to solve the above-mentioned problems of the prior art, a vehicle-mounted navigation device according to the present invention provides a display unit for providing guide information to a user, an information input unit for inputting information specified by the user, and advertisement information. Content storage means for storing content including POI information indicating the location of a facility or property; and when a destination and a waypoint on the way are set via the information input means, Guide destination registering means for registering each passing point as a guide destination, and control means operably connected to the display means, information input means, content storage means and guide destination registering means, the control means, When the information of the content is displayed on the screen of the display unit, instruction information for selecting a provision location of the advertisement information related to the content as a guide destination is input. When the destination is registered, the POI information of the content is provided to the destination registering means so that the search route to the destination is in the optimal guide order without changing the guide order of the currently registered destination. It is characterized by registering.
[0015]
ADVANTAGE OF THE INVENTION According to the vehicle-mounted navigation device which concerns on this invention, when the information of the content containing the POI information which points out the location of the facility or article which provides advertisement information is displayed on the screen of a display means, via an information input means When the user inputs instruction information to select the location where the advertisement information related to the content is provided as the guide destination, the control means thereafter controls the guide destination (destination, passage, etc.) currently registered in the guide destination registration means. The POI information of the content is automatically registered so that the search route to the destination becomes the optimal guidance order without changing the guidance order of (point).
[0016]
That is, when adding the POI information of the content to the route guidance, the POI information is automatically registered in the most efficient order without changing the guidance order of the currently registered guide destination. As described above, the user does not need to consider the guidance order by himself or perform an operation for registration, and the time for the registration is not required, so that the user's convenience can be improved.
[0017]
In addition, from the user's point of view, when the user checks the information of the content on the screen of the display unit and inputs an instruction as to whether or not to go to a place where the advertisement information related to the content is provided, the user can concentrate on driving afterward. Therefore, it is possible to reduce the risk of an accident due to extra findings.

[0030]
FIG. 2 shows an example of a screen display when route guidance is provided to a destination via a passing point, and a display example before registration of POI information of push-type content (FIG. 2A). And a display example ((b) in the same figure) after registration. In the illustrated example, the vehicle position mark CM indicating the current position of the vehicle is displayed on the map image displayed on the display screen 40 of the display device 6 via the image combining unit 22 under the control of the control unit 17. An example is shown in which guidance routes GR, GR1 from the vehicle position (CM) to the destination G are displayed together with the destination (destination) G and the passing points (stop points) P1, P2 on the way. The guidance routes GR and GR1 are displayed in a display mode different from that of other roads (for example, the line width is widened or displayed in a conspicuous color) so that the user can easily identify them. Further, in FIG. 2B, POI information of the push-type content registered in the guide destination registration unit 25 based on the control from the control unit 17 (providing location AP of the advertisement information related to the content) is added as described later. Is displayed.
[0031]
As can be seen by comparing the display examples of (a) and (b) of FIG. 2, the guidance order of the guidance destination initially registered in the guidance destination registration unit 25: (CM) → P1 → P2 → G is not changed. Is maintained as it is. In other words, the vehicle-mounted navigation device 30 according to the present embodiment, when adding the provision location AP of the advertisement information relating to the content including the POI information to the route guidance, the guidance order of the currently registered guidance destination: (CM) → Without changing P1 → P2 → G, the POI information is registered at the most efficient and optimal order and route guidance to the destination G ((CM) in the example shown → P1 → AP → P2 → G) is performed. In the embodiment to be described later, the POI information is registered so that the guidance order in which the distance of the search route to the destination G is the shortest is registered. Other conditions can be used, such as in order.
[0032]
Hereinafter, the route guidance process related to the registration of the POI information of the push-type content performed by the vehicle-mounted navigation device 30 according to the present embodiment will be supplementarily described with reference to FIGS. 3 to 5 illustrating an example of the process flow. This will be described with reference to FIGS.
[0033]
First, as an initial state, it is assumed that the own vehicle is in a stopped state, and the content information storage unit 24 is in a state where content information has not been stored yet.
[0034]
Referring to FIG. 3, in the first step S <b> 1, the control unit 17 has performed an operation of setting a guide destination (a destination and a passing point on the way) by the user via the operation unit 2 (remote control transmitter) ( YES) or not (NO). If the determination result is YES, the process proceeds to step S2, and if the determination result is NO, the determination process is repeated until there is a guide destination setting operation. Each data such as the set destination is registered in the guide destination registration unit 25 via the interface 12 and the control unit 17.
[0035]
In the next step S2, based on the route guidance function, the vehicle searches for a guidance route to the destination to which the vehicle should travel, and displays the searched guidance route on the map screen of the display device 6 (route guidance start). .
[0036]
That is, the map data reading control unit is controlled by the control unit 17 based on the data of the destination registered in the guide destination registration unit 25 and the data of the current position of the vehicle detected based on the output signal of the GPS receiver 4. 11 to read the map data in the range from the departure place (own vehicle position) to the destination from the disk 1a to the buffer memory 16 via the HDD 1 and further to read the data stored in the guidance route storage unit 20. With reference to the navigation route, the navigation route connecting the departure point and the destination at the shortest distance is searched by a horizontal search method or the like, and the searched guidance route is displayed by being superimposed on the map image displayed on the screen of the display device 6. Then, route guidance is started (see FIG. 2A). At this time, passing points (stop points) P1 and P2 on the way to the destination (destination) G are also displayed on the map image. The guidance route GR is displayed in a display mode different from other roads as described above. Thereby, the user can grasp the guidance route GR through which the vehicle (CM) is to be guided to the destination G through the display screen 40 of the display device 6.
[0037]
In the next step S3, the control unit 17 determines whether or not the push-type content including the POI information has been delivered from the server 50 via the communication device (eg, mobile phone) 3 (YES) or not (NO). . If the determination result is YES, the process proceeds to step S4, and if the determination result is NO, the determination process is repeated until the push-type content is distributed.
[0038]
In the next step S4, the control unit 17 temporarily stores the information of the content received via the communication device 3 in the content information storage unit 24.
[0039]
In the next step S5, the control unit 17 determines whether or not the own vehicle has stopped (stopped) (YES) or not (NO). This determination is made based on the traveling speed of the vehicle detected based on the output signal of the self-contained navigation sensor 5, or based on the presence or absence of a parking brake signal. If the result of the determination is YES (for example, when waiting for a traffic light at an intersection, when stopping at one of the passing points, etc.), the process proceeds to step S6, and when the result of the determination is NO, the process returns to step S3. The above process is repeated.
[0040]
In the next step S6, the control unit 17 determines whether or not the vehicle has traveled a predetermined distance or more from the providing location of the advertisement information related to the content (the position indicated by AP in FIG. 2B) as the own vehicle travels (YES). (NO) is determined. If the determination is YES, the process proceeds to step S7, and if the determination is NO, the process proceeds to step S8 (FIG. 4).
[0041]
In step S7 (that is, when the position of the advertisement information has become far from the provision location of the advertisement information due to the movement of the vehicle position), the control unit 17 deletes the information of the content once stored in the content information storage unit 24. Thereafter, the process returns to step S3 to repeat the above processing.
[0042]
Next, referring to FIG. 4, in step S <b> 8 (the host vehicle is in a stopped state), the control unit 17 transmits the information of the content once stored in the content information storage unit 24 via the image synthesis unit 22 to the display device. 6 is displayed on the screen. At this time, although not specifically shown, three parts of “go”, “hold”, and “delete” are provided on a part of the display screen to allow the user to select how to respond to the information of the content. Two choices are displayed.
[0043]
In the next step S9, the control unit 17 provides a place where the advertisement information related to the content is provided (see FIG. 2B) by the user operating the operation unit 2 (remote control transmitter) or touching the display screen. It is determined whether or not instruction information for selecting (the position indicated by the AP) as the guide destination has been input, that is, whether or not “go” has been selected (YES) or not (NO). If the determination is YES, the process proceeds to step S10, and if the determination is NO, the process proceeds to step S13.
[0044]
In step S10, the control unit 17 determines whether the advertisement information included in the content is related to a time service, that is, whether the content includes time information (YES) or not (NO). judge. When the result of the determination is YES, the process proceeds to step S21 (FIG. 5), and when the result of the determination is NO, the process proceeds to step S11.
[0045]
In step S11 (that is, in the case of normal advertisement information that does not include the time information specified for the time zone in which the service related to the advertisement information can be enjoyed), the control unit 17 registers the information currently registered in the guide destination registration unit 25. Without changing the guidance order of the guidance destination ((CM) → P1 → P2 → G in the example of FIG. 2), the content of the content is set so that the distance of the search route to the destination G becomes the shortest. The POI information is registered in the destination registration unit 25.
[0046]
Specifically, as shown as an example in FIG. 6, the current guidance order: (CM) → P1 → P2 → G is maintained without change, and the POI information of the content (the relevant The case where the advertisement information providing location AP relating to the content is added first (FIG. (A)), the case where it is added second (FIG. (B)), and the case where it is added third (FIG. (C)) ) And the case of the last addition ((d) in FIG. 6), a route search is performed, and based on the search results, a search route having the shortest total distance among the search routes SR1 to SR4 (in this case, FIG. b) SR2) is determined, and the POI information (the advertisement information providing location AP) is added second on the determined search route SR2. That is, the new guidance order: (CM) → P1 → AP → P2 → G is registered in the guidance destination registration unit 25. The determined search route SR2 is guided as a new guidance route (GR1 in FIG. 2B).
[0047]
In the next step S12, the guidance destination currently registered in the guidance destination registration unit 25 and the POI information newly registered are displayed on the screen of the display device 6 via the image synthesizing unit 22 under the control of the control unit 17. Is displayed together with the guidance route to the destination searched based on the map data (see FIG. 2B). At this time, in order to make it easy for the user to recognize, the registered POI information may be displayed in a display mode different from other display information (for example, blinking mode). Then, this processing flow is “end”.
[0048]
On the other hand, in step S13, the control unit 17 determines whether “hold” or “delete” is selected by a remote control operation or a screen touch operation by the user. If “hold” is selected, the process proceeds to step S14, where the control unit 17 stores the POI information of the content as a user registration POI, and returns to step S3 (FIG. 3) to repeat the above processing. On the other hand, if "Erase" is selected, the process proceeds to step S15, where the control unit 17 deletes the information of the content stored in the content information storage unit 24, and returns to step S3 to repeat the above processing.
[0049]
Next, referring to FIG. 5, in step S21 (that is, when the advertisement information included in the content is related to the time service), the control unit 17 causes the guide destination currently registered in the guide destination registration unit 25 to be registered. Without changing the guidance order (P1 → P2 → G in the example of FIG. 2), the estimated time of arrival at the location where the advertisement information related to the content is provided is calculated for the shortest search route to the destination. Details of the processing performed in this step will be described later.
[0050]
In the next step S22, the control unit 17 determines whether or not the own vehicle can arrive in time for providing the advertisement information (YES) or not (NO). When the result of the determination is YES, the process proceeds to step S23, and when the result of the determination is NO, the process proceeds to step S24. Details of this processing will also be described later.
[0051]
In step S23, the control unit 17 registers the POI information of the content in the guidance order in the guidance destination registration unit 25 (that is, the guidance order in which the distance of the search route to the destination is the shortest). Details of this processing will also be described later. Thereafter, the process proceeds to step S12 (FIG. 4), and as described above, the registered POI information is maintained without changing the guide order ((CM) → P1 → P2 → G in the example of FIG. 2A). Is additionally displayed to continue the route guidance.
[0052]
On the other hand, in step S24, the control unit 17 determines whether there is another route to be searched for to the destination without changing the guidance order of the currently registered guide destination (YES) or not (NO). If the result of the determination is YES, the process returns to step S21 to repeat the above processing, and if the result of the determination is NO, the process proceeds to step S25.
[0053]
In step S25 (that is, when the time service cannot be enjoyed due to the time being taken for any search route to the destination), the control unit 17 deletes the information of the content stored in the content information storage unit 24. . Thereafter, the process returns to step S3 (FIG. 3) to repeat the above processing.
[0054]
The processing performed in steps S21 to S23 and S24 (in the case of YES) determines the guidance order of the POI information (the provision location of the advertisement information related to the time service) to be registered in the guidance destination registration unit 25 as a whole. . A method of determining the guidance order for registering the POI information will be described with reference to FIG.
[0055]
Basically, in the same manner as in the case of normal advertisement information (the processing performed in step S11), the current guidance order: (CM) → P1 → P2 → G POI information of the content is added to the place where the distance of the search route to the destination is the shortest (providing the advertisement information providing location AP of the content). Calculate the time and check if you can arrive within the time service time. If it is not likely to be in time, the place to be added is adjusted back and forth as appropriate.
[0056]
More specifically (see FIG. 7), the POI information (the position of the advertisement information providing location AP) and the GPS receiver are searched for the search route having the shortest distance (in this case, SR2 in FIG. 7B). 4, the current position (CM) of the vehicle detected based on the output signal, the traveling speed of the vehicle detected based on the output signal of the self-contained navigation sensor 5, and the current time at the vehicle position (15 in this case). : 30), an estimated time of arrival at the provision location AP of the advertisement information (in this case, 16:10) is calculated, and the calculated expected time of arrival and time information included in the content (in this case, 15:00). １６16: 00), it is checked whether it is possible to arrive within the time of the time service. In this case, since the time is not enough in time, a search route (in this case, SR1 in FIG. 7A) in which the distance to the destination is the next shortest is similarly estimated arrival time (in this case, 15:40), and based on comparison with the time information, it is checked whether or not it is in time. In this case, since it is possible to arrive within the time of the time service, the POI information (AP) is added first on the search route SR1. That is, the new guidance order: (CM) → AP → P1 → P2 → G is registered in the guidance destination registration unit 25.
[0057]
As described above, according to the in-vehicle navigation device 30 according to the present embodiment, as shown in the processing flow of FIGS. 3 to 5, the POI information is included while the route guidance is being performed toward the destination. When the push type content is distributed (S1 to S3), the information of the content is temporarily stored in the content information storage unit 24, and when the own vehicle is stopped, for example, at a traffic intersection at an intersection. (S5), the information of the content is displayed on the screen of the display device 6 (S8), and for the displayed information of the content, the user selects a providing location AP of the advertisement information related to the content as a guide destination. When an operation of “go” is performed (S9), the control unit 17 thereafter guides the guidance destinations currently registered in the guidance destination registration unit 25: (CM) → P1 → The POI information is automatically registered so that the guide order in which the distance of the search route to the destination is the shortest without changing 2 → G (S11, FIG. 6). The currently registered guidance destination and the newly registered POI information are displayed together with a new guidance route (GR1 in FIG. 2B) according to a new guidance order: (CM) → P1 → AP → P2 → G. It is displayed on the screen of the device 6.
[0058]
Further, when the advertisement information included in the content is related to the time service, the guide destination registration unit is configured based on the estimated arrival time at the providing location AP of the advertisement information and the time information included in the content. The guidance order of the POI information to be registered in the P.25 is determined (S21 to S23 and S24, FIG. 7).
[0059]
As described above, according to the present embodiment, when adding the POI information of the content to the route guidance, the POI information is stored in the most efficient order without changing the guidance order of the currently registered guide destination. Since the automatic registration is performed, the user does not need to consider the guidance order by himself or perform an operation for registration as in the related art, and the time for the registration is not required. This greatly improves user convenience.
[0060]
Further, when the user confirms the information of the content on the screen of the display device 6, if the user inputs an instruction as to whether or not to go to the provision location AP of the advertisement information related to the content, the control unit 17 It is possible to concentrate on driving and concentrate on driving, so that it is possible to reduce the risk of causing an accident due to extra observations.
[0061]
In the embodiment described above, when the push-type content is delivered while route guidance is being performed to the destination, the POI information (the place where the advertisement information is provided) included in the content is added to the new guide destination. Although the case of registering as PO has been described as an example, the form of registering POI information as a guide destination is of course not limited to this. For example, when the push-type content is delivered without the route guidance being provided, the location (POI information) where the advertisement information related to the content is provided is registered as the destination (destination), and the advertisement is directed to the destination. Route guidance may be started. FIG. 8 shows an example of the processing flow in that case.
[0062]
Similarly, in this processing flow (FIG. 8), it is assumed that, as an initial state, the own vehicle is in a stopped state, and the content information storage unit 24 is in a state where the content information has not been stored yet.
[0063]
Referring to FIG. 8, in first step S31, control unit 17 determines whether push type content including POI information has been delivered from server 50 via communication device (such as a mobile phone) 3 (YES) (step S31). NO). When the result of the determination is YES, the process proceeds to step S32, and when the result of the determination is NO, the determination process is repeated until the push-type content is delivered.
[0064]
In the next step S32, the control unit 17 temporarily stores the information of the content received via the communication device 3 in the content information storage unit 24.
[0065]
In the next step S33 (the host vehicle is in a stopped state), the control unit 17 displays the information of the content once stored in the content information storage unit 24 on the screen of the display device 6 via the image synthesis unit 22. . In this case, similarly, a selection item for allowing the user to select how to respond to the information of the content is displayed on a part of the display screen.
[0066]
In the next step S34, there has been an operation in the control unit 17 to set the provision location of the advertisement information related to the content as the destination by the operation of the user via the operation unit 2 (remote control transmitter) (YES). ) Or not (NO). If the determination result is YES, the process proceeds to step S35, and if the determination result is NO, the determination process is repeated until there is a guide destination setting operation. The data of the set destination (destination) is registered in the destination registration unit 25 via the interface 12 and the control unit 17.
[0067]
In the next step S35, similarly to the processing performed in step S2 (FIG. 3), a guidance route to the destination is searched for, and the searched guidance route is displayed on the map screen of the display device 6 (route guidance). start). Then, this processing flow is “end”.
[0068]
【The invention's effect】
As described above, according to the present invention, when adding POI information (a place where advertisement information is provided) to route guidance as a guide destination, the POI information can be automatically registered in the most efficient order. This eliminates the need for the user to consider the guidance order by himself or to perform an operation for registration as in the related art, thereby improving user convenience.
