Here, in particular, the vehicle speed sensor 22 is a sensor for detecting a moving distance and a vehicle speed of the vehicle, generates a pulse according to the rotation of the driving wheel of the vehicle, and outputs a pulse signal to the navigation ECU 13. And navigation ECU13 calculates the rotational speed and moving distance of a driving wheel by counting the generated pulse. Note that the navigation device 1 does not have to include all of the above five types of sensors, and the navigation device 1 may include only one or more of these types of sensors.

  Further, the data recording unit 12 reads an external storage device and a hard disk (not shown) as a recording medium, a map information DB 31, a stay history DB 32, a scheduled stay time setting data 33, a predetermined program, and the like recorded on the hard disk. A recording head (not shown) as a driver for writing predetermined data to the hard disk is also provided.

  Here, the map information DB 31 includes, for example, link data 34 relating to roads (links), node data 35 relating to node points, facility data 36 relating to facilities, map display data for displaying maps, intersection data relating to each intersection, and routes. It is a storage means in which search data for searching, search data for searching for points, and the like are stored.

Further, as the facility data 36, information related to a facility that is a departure point, a destination, a guidance target, and the like in the navigation device 1 is stored. For example, accommodation facilities such as hotels and inns, refueling facilities such as gas stations, commercial facilities such as shopping malls, supermarkets, shopping centers, entertainment facilities such as theme parks and game centers, dining facilities such as restaurants, bars and taverns, and public facilities Information on parking facilities such as parking lots, transportation facilities, religious facilities such as temples and churches, public facilities such as museums and museums, and the like.
The facility data 36 includes, for each facility, a facility number that is an identifier of the facility, a facility name that indicates the name of the facility, and a facility genre that indicates the genre of the facility (such as “parking lot”, “post office”, and “restaurant”). It is composed of position coordinates indicating the position of the facility. Further, the facility data 36 also stores dependency relationships between facilities. For example, if the facility is a parking lot and the parking lot belongs to another nearby facility (for example, a parking lot for users of theme parks or shopping malls), The facility data of the subordinate is also stored as facility data of the car park.

Here, FIG. 2 is a diagram showing an example of the facility data 36.
For example, the example of the facility data 36 shown in FIG. 2 indicates that “XX land” (genre: amusement park) corresponding to the facility number: “10001” is installed at the point of coordinates (x1, y1). ing. In addition, it is shown that “◯ × parking lot” (genre: parking lot) corresponding to the facility number: “10002” is installed at the point of coordinates (x2, y2). Furthermore, XX parking lot indicates that it is a parking lot belonging to XX land. Similarly, information on other facilities is also stored.

  When the navigation device 1 performs the facility search process, the facility device 36 searches the facility corresponding to the genre selected by the user using the facility data 36, and stores the facility information related to the facility that meets the search condition in the map information DB 31. Get from. Then, by displaying a landmark for the corresponding position of the map image displayed on the liquid crystal display 15, or by displaying a list of facility names, distances from the current position, required time, etc. that meet the search conditions. Information on facilities is guided to the user. In addition, when the user performs an operation of setting a facility to which the user is guided or a facility located in the vicinity thereof as a destination or a waypoint, a guidance route is set with the facility set as a destination or a waypoint.

  The stay history DB 32 is a DB that accumulates and stores the history of the time that the user stayed at the facility in the past. Specifically, the ignition is turned off when the vehicle reaches a predetermined distance (for example, within 100 m) of the destination with the destination set in the navigation apparatus 1 and the ignition is turned off and then turned on. The period from when it is turned on until it is turned on is stored as the time spent at the facility set as the destination. However, a facility (for example, a parking lot belonging to a theme park or a shopping mall) set as a destination as described later is set as a destination via a facility (for example, a theme park or a shopping mall) other than the facility. If it is, it is stored as the time spent at a facility (for example, a theme park or a shopping mall) other than the facility.

Here, FIG. 3 is a diagram showing an example of the storage area of the stay history DB 32.
As shown in FIG. 3, the stay history DB 32 stores the date and time of staying at the facility, the staying time of the facility, and the staying facility (that is, the facility set as the destination) in association with each other. For example, in the example shown in FIG. 3, the user stayed at “XX department store” for 1 hour and 45 minutes at 17:45 on July 25, 2010 (that is, belongs to “XX department store” or “XX department store”). The vehicle arrives within a predetermined distance of the destination with other facilities (such as a parking lot) set as the destination, and the ignition is turned off and turned on after 1 hour 45 minutes). Similarly, other stay histories are also stored.
Then, the navigation ECU 13 sets a planned stay time for each facility or each genre of the facility as described later, based on the stay history of the user's facility stored in the stay history DB 32.

  Further, the planned stay time setting data 33 is data for specifying a time during which the user is expected to stay for each facility (hereinafter referred to as a planned stay time). In the present embodiment, the scheduled stay time is calculated based on the stay history stored in the stay history DB 32 as an average of the time that the user stayed in the facility in the past. In addition, you may set the scheduled stay time for every genre instead of every facility.

Here, FIG. 4 is a diagram showing an example of the planned stay time setting data 33.
As shown in FIG. 4, the planned stay time setting data 33 stores a facility and the planned stay time that the user is expected to stay at the facility in association with each other. For example, in the example shown in FIG. 4, the planned stay time of “XX Land” is set to 5 hours and 50 minutes. Similarly, for other facilities, the planned stay time is set for each facility.
Then, the navigation ECU 13 cancels the destination setting based on the setting of the planned stay time stored in the planned stay time setting data 33 as described later.

For example, a mobile phone or DCM.

  Next, a destination setting processing program executed by the CPU 51 in the navigation device 1 having the above-described configuration will be described with reference to FIG. FIG. 6 is a flowchart of the destination setting processing program according to the present embodiment. Here, the destination setting processing program is executed after the ACC of the vehicle is turned on, searches for facilities that satisfy the input conditions, and searches for the searched facilities or other facilities located around the searched facilities. It is a program to set to. The programs shown in the flowcharts of FIGS. 6, 10, and 11 below are stored in the RAM 52 and the ROM 53 provided in the navigation device 1 and are executed by the CPU 51.

  First, in step (hereinafter abbreviated as S) 1 in the destination setting processing program, the CPU 51 performs facility search processing. In the facility search process, based on the facility data 36 stored in the map information DB 31, a facility that matches the search conditions such as the facility name, address, and genre input by the user is searched.

  Next, in S2, the CPU 51 determines whether or not at least one facility that matches the search condition has been searched as a result of the facility search process in S1. If it is determined that at least one facility that matches the search condition has been searched (S2: YES), the process proceeds to S3. On the other hand, if it is determined that the facility that matches the search condition cannot be searched (S2: NO), the destination setting processing program is terminated.

  In S3, the CPU 51 extracts the facility data 36 (facility name, position coordinates, etc.) of the facility determined to meet the search condition from the map information DB 31 based on the result of the search processing in S1. Based on the extracted facility data 36, a list of facilities determined to meet the search conditions is displayed on the liquid crystal display 15.

  FIG. 7 is a diagram showing an example of the facility guidance screen 61 displayed on the liquid crystal display 15 in S3. As shown in FIG. 7, on the facility guidance screen 61, information about facilities that meet the search condition (genre “theme park” in the example shown in FIG. 7) is displayed in the information window 62 in the order from the current position of the vehicle. In addition, as information on the facility, a facility name, a distance from the current position, a required time, and the like are displayed. Then, the user can acquire information on the facility that meets the search condition by viewing the facility guidance screen 61. Further, by selecting the information window 62, it is possible to display a map around the corresponding facility or set it as a destination as will be described later.

  Subsequently, in S4, the CPU 51 determines whether or not a facility has been selected based on a user operation from the list of facilities displayed on the liquid crystal display 15 in S3. Specifically, when the information window 62 displayed on the facility guidance screen 61 shown in FIG. 7 is selected, it is determined that the facility indicated by the information window 62 has been selected.

  If it is determined that the facility has been selected from the facility list (S4: YES), the process proceeds to S5. On the other hand, if it is determined that the facility is not selected from the facility list (S4: NO), the process waits until it is selected.

  In S <b> 5, the CPU 51 displays a map around the facility selected from the facility list on the liquid crystal display 15.

  Here, FIG. 8 is a diagram showing an example of the surrounding map guidance screen 71 displayed on the liquid crystal display 15 in S5. As shown in FIG. 8, in the surrounding map guidance screen 71, the facility 72 selected from the facility list (that is, the facility searched by the user, “XX Land” in the example shown in FIG. 8) and its facility A map around is displayed. In addition, on the surrounding map guidance screen 71, a cursor 73 displayed in the center of the screen, a movement arrow 74 arranged in eight directions around the cursor 73, a partner parking lot button 75, a destination setting button 76, and the like are arranged. When the movement arrow 74 is pressed, the map moves in the direction indicated by the pressed arrow. When the partner parking lot button 75 is pressed, a parking lot belonging to the facility selected from the facility list (so-called partner parking lot) is searched, and a list of searched partner parking lots is displayed. When the destination setting button 76 is pressed, the point or facility indicated by the cursor 73 at the time of pressing is set as the destination.

  Accordingly, in the surrounding map guidance screen 71, the searched facility 72 can be set as the destination by pressing the destination setting button 76 in the initial state where the surrounding map guidance screen 71 is displayed. By operating the moving arrow 74, it is possible to set another facility or point as the destination. For example, in a large facility such as a theme park or a shopping mall, the location of the facility and the parking lot may be separated. In that case, it is better to set the parking lot instead of the facility as the destination and search for a suitable guidance route It becomes possible. Therefore, as shown in FIGS. 8 and 9, when three parking lots 77 to 79 belonging to “XX land” are arranged around “XX land” which is the searched facility 72, By pressing the movement arrow 74, the cursor 73 is moved to one of the parking lots 77 to 79, and by pressing the destination setting button 76, any one of the parking lots 77 to 79 is selected instead of the searched facility 72. It becomes possible to set the destination. Further, a list of parking lots 77 to 79 belonging to the found facility 72 is displayed by pressing the partner parking lot button 75, and a selection is made by selecting a parking lot from the displayed parking lots 77 to 79. It is also possible to set the reserved parking lot as the destination. And in this embodiment, after displaying the surrounding map of the facility (henceforth a search facility) searched by the facility search process as mentioned above, facilities other than a search facility are made into the destination on the displayed surrounding map. When set, or when a list of partner parking lots is displayed and a destination is set from the displayed list of partner parking lots, the facility set as the destination is designated as a destination via a facility other than the facility. It is considered to have been set on the ground.

  Next, in S6, the CPU 51 determines whether or not the user has performed a destination setting operation on the surrounding map displayed on the liquid crystal display 15 in S5. Specifically, it is determined whether or not the destination setting button 76 is pressed while the surrounding map guidance screen 71 is displayed.

  When it is determined that the destination setting operation has been performed (S6: YES), the process proceeds to S7. On the other hand, when it is determined that the destination setting operation has not been performed (S6: NO), the destination setting process is terminated without setting the destination.

  In S <b> 7, the CPU 51 sets the point or facility selected by the cursor 73 on the surrounding map guidance screen 71 as the destination of the navigation device 1. In addition, the CPU 51 searches for a guidance route to the set destination. After that, traveling guidance is performed according to the searched guidance route. The mark displayed to indicate the position of the destination on the map during driving guidance is displayed when the facility set as the destination is set as the destination through a search facility other than the facility. It may be displayed on the facility set on the ground or may be displayed on the search facility. In addition, it may be displayed on the facility set as the destination and on the search facility, respectively, or each display mode may be changed. For example, either one may be displayed with a tone down

  Next, the planned stay time setting processing program executed by the CPU 51 in the navigation device 1 will be described with reference to FIG. FIG. 10 is a flowchart of the scheduled stay time setting processing program according to the present embodiment. Here, the planned stay time setting processing program is a program that is executed after the ACC of the vehicle is turned on and sets the planned stay time for each facility from the history of the stay time in the facility.

  First, in S11 in the planned stay time setting processing program, the CPU 51 determines whether or not the ignition of the vehicle is turned on.

  If it is determined that the ignition is turned on (S11: YES), the process proceeds to S12. On the other hand, when it is determined that the ignition is not turned on (S11: NO), the scheduled stay time setting processing program is terminated.

  Next, in S12, the CPU 51 determines whether or not the destination is set in the navigation device 1 when the immediately preceding ignition is turned off and the vehicle is located within a predetermined distance (for example, within 100 m) of the destination. .

  If the destination is set when the immediately preceding ignition is turned off and it is determined that the vehicle is located within a predetermined distance from the destination (S12: YES), the process proceeds to S13. On the other hand, when it is determined that the destination is not set at the time when the immediately preceding ignition is turned off or when it is determined that the vehicle is not located within the predetermined distance of the destination (S12: NO), The scheduled stay time setting processing program is terminated.

  In S13, the CPU 51 calculates the staying time at the user's facility. More specifically, the period from when the ignition is turned off immediately before it is turned on is calculated as the time spent at the facility.

  Next, in S14, the CPU 51 determines whether or not the destination set at the time when the immediately preceding ignition is turned off is a facility and set as a destination via a search facility other than the facility. In the present embodiment, as described above, after displaying the surrounding map of the search facility searched by the facility search processing (S1), the facility other than the search facility is set as the destination on the displayed peripheral map. Or if you display a list of partner parking lots and set the destination from the displayed list of partner parking lots, the facility set as the destination is set as the destination via a facility other than the facility (See FIGS. 8 and 9).

  If it is determined that the destination set at the time when the immediately preceding ignition is turned off is a facility and set as the destination via a search facility other than the facility (S14: YES) To S16. On the other hand, when the destination set at the time when the immediately preceding ignition is turned off is not a facility or when the destination is not set through a search facility other than the facility (S14: NO), The process proceeds to S15.

  In S15, the CPU 51 stores the stay time calculated in S13 in the stay history DB 32 (FIG. 3) as the stay time of the facility set as the destination (hereinafter referred to as the destination facility). Thereafter, the process proceeds to S17.

  On the other hand, in S16, the CPU 51 stores the stay time calculated in S13 in the stay history DB 32 (FIG. 3) as the stay time of the search facility. For example, as shown in FIG. 8 and FIG. 9, when the parking lots 77 to 79 belonging to “XX land” are selected after displaying the surrounding map of “XX land” which is the facility 72 searched, “ “○ land” is the search facility.

  Next, in S <b> 17, the CPU 51 reads the planned stay time setting data 33 (FIG. 4) stored in the data recording unit 12 and updates the planned stay time of the corresponding facility. That is, when the stay history of the destination facility is stored in S15, the planned stay time of the destination facility is updated. When the stay history of the search facility is stored in S16, the search facility is updated. Update planned stay time for. In the present embodiment, the planned stay time is an average of the time that the user has stayed in the facility in the past, and is calculated based on the stay time history of the facility to be updated.

  Next, the destination cancellation processing program executed by the CPU 51 in the navigation device 1 will be described with reference to FIG. FIG. 11 is a flowchart of the destination cancellation processing program according to this embodiment. Here, the destination cancellation processing program is a program that is executed after the ACC of the vehicle is turned on and cancels the destination setting when a predetermined condition is satisfied.

  First, in the destination cancellation processing program, in S21, the CPU 51 determines whether or not a destination is set in the navigation device 1. The destination setting of the navigation device 1 is performed in the above-described destination setting processing program (FIG. 10).

  And when it determines with the destination being set to the navigation apparatus 1 (S21: YES), it transfers to S22. On the other hand, when it is determined that the destination is not set (S21: NO), the destination cancellation processing program is terminated.

  In S22, the CPU 51 determines whether or not the vehicle has stopped.

  And when it determines with the vehicle having stopped (S22: YES), it transfers to S23. On the other hand, when it is determined that the vehicle is not stopped (S22: NO), the destination cancellation processing program is terminated.

  In S <b> 23, the CPU 51 acquires the current position of the vehicle from the current position detection unit 11, and acquires information regarding the position coordinates of the destination set in the navigation device 1 from the map information DB 31.

  Subsequently, in S24, the CPU 51 determines whether or not the current position of the vehicle is located within a predetermined distance (for example, within 100 m) from the destination set in the navigation device 1 based on the information acquired in S23. .

  When it is determined that the vehicle is located within a predetermined distance from the destination (S24: YES), the process proceeds to S25. On the other hand, when it is determined that the vehicle is not located within the predetermined distance from the destination (S24: NO), the destination cancellation processing program is terminated.

  In S25, the CPU 51 determines whether or not the destination set in the navigation device 1 is a facility and is set as a destination via a search facility other than the facility. In the present embodiment, as described above, after displaying the surrounding map of the search facility searched by the facility search processing (S1), the facility other than the search facility is set as the destination on the displayed peripheral map. Or if you display a list of partner parking lots and set the destination from the displayed list of partner parking lots, the facility set as the destination is set as the destination via a facility other than the facility (See FIGS. 8 and 9).

  If it is determined that the destination set in the navigation device 1 is a facility and set as a destination via a search facility other than the facility (S25: YES), the process proceeds to S27. . On the other hand, when the destination set in the navigation apparatus 1 is not a facility or when the destination is not set through a search facility other than the facility (S25: NO), the process proceeds to S26.

  In S <b> 26, the CPU 51 reads the planned stay time of the destination facility set as the destination in the navigation device 1 from the planned stay time setting data 33. Thereafter, the process proceeds to S28.

  On the other hand, in S <b> 27, the CPU 51 reads the planned stay time of the search facility from the planned stay time setting data 33. For example, as shown in FIG. 8 and FIG. 9, when the parking lots 77 to 79 belonging to “XX land” are selected after displaying the surrounding map of “XX land” which is the facility 72 searched, “ The planned stay time of “XX Land” is read out.

  Next, in S28, the CPU 51 determines whether or not the planned stay time read in S26 or S27 has elapsed since the vehicle stopped within a predetermined distance from the destination.

  When it is determined that the planned stay time or more read in S26 or S27 has elapsed since the vehicle stopped within a predetermined distance from the destination (S28: YES), the destination facility is set to the destination. The setting is canceled (S29). Along with that, the guide route is also deleted, and the travel guidance is also stopped. Also, the mark displayed to indicate the position of the destination on the map is deleted.

  On the other hand, if it is determined that the planned stay time read in S25 or S26 has not elapsed since the vehicle stopped within a predetermined distance from the destination (S28: NO), the destination setting is canceled. The destination cancellation processing program is terminated without doing so.

As described in detail above, the navigation device 1 according to the present embodiment, the travel guidance method using the navigation device 1 and the computer program executed by the navigation device 1 search for facilities based on the search conditions input by the user ( S1) A surrounding map of the found facility is displayed on the liquid crystal display 15 (S5), and a point or facility selected on the displayed surrounding map is set as the destination (S7). When the vehicle stops within a predetermined distance from the destination and the destination is set through a search facility other than the destination facility, the vehicle stops within the predetermined distance of the destination. It is determined whether or not the estimated stay time of the search facility has elapsed (S28), and if it is determined that the estimated stay time has elapsed, the destination setting is canceled (S29), so that the vehicle is set as the destination. It is possible to cancel the destination setting at a timing when an appropriate time has passed while the vehicle is located within a predetermined distance from the facility. As a result, it is possible to prevent the setting of the destination from being canceled even if the destination has not been reached, or the setting of the destination from being canceled even when the destination has been reached.
Also, in the destination setting process, after a map of the searched facility is displayed, if a facility other than the searched facility is set as the destination on the displayed map, a list of partner parking lots is displayed. When the destination is set from the displayed list of partner parking lots, the user predicts that he / she will stay at the searched facility instead of the facility set as the destination, and the facility set as the destination The destination setting is canceled based on the estimated staying time of the searched facility. Therefore, the destination setting can be canceled at an appropriate time when the vehicle is located within a predetermined distance from the facility set as the destination.

Note that the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the scope of the present invention.
For example, in this embodiment, in the planned stay time setting data 33, the planned stay time is set for each facility, but may be set for each genre of the facility. In this case, the average stay time of facilities belonging to the same genre is set as the planned stay time of the genre. In S26, it is desirable to read the planned stay time corresponding to the genre to which the destination facility belongs, and in S27 to read the planned stay time corresponding to the genre to which the search facility belongs.

  In this embodiment, the destination is canceled when the vehicle stops within the predetermined distance within the predetermined distance from the destination. However, regardless of whether the vehicle is stopped, the vehicle is removed from the destination. It is good also as a structure which cancels | releases a destination, when staying within the predetermined distance more than the applicable scheduled stay time. The predetermined distance may be changed for each destination facility and each destination facility genre.

  Moreover, in this embodiment, after displaying the surrounding map of the search facility searched by the facility search process (S1), when a facility other than the search facility is set as the destination on the displayed peripheral map, It is considered that the facility set in is set as the destination via a facility other than the facility (see FIGS. 8 and 9), but the destination facility belongs to the search facility (in particular, the parking lot belonging to the search facility) ) May be added as a condition.
