Description

  The present invention relates to a navigation apparatus, and more particularly to a technique for automatically displaying peripheral facilities by predicting a user's movement after arrival at a destination.

  Currently, a navigation system that searches for a route to a destination and guides the route is developed and used in a vehicle, a portable terminal, or the like. The scale (scale) of the map displayed on the display of the navigation device can be changed according to a user instruction. In the case of a wide area map, a main road or a main road that can be a route search target is displayed at the center. On the other hand, a detailed map (city map) displays a POI (Point of Interest) icon indicating a narrow street, the type and location of a facility, and the like. It is also possible to display the facility as a three-dimensional image at an intersection or the like.

  In Patent Document 1, a narrow street map of a scale capable of displaying both the current position and the destination point is displayed on the display at a point just before arrival at the guidance end point. Then, as the vehicle approaches the destination, it switches to a large scale narrow street map.

  In Patent Document 2, when the destination is searched for the original destination after arriving at the set destination, the set destination is displayed at the center of the map screen and the angle of the map screen is fixed by arriving at the destination. It is intended to clarify the relative positional relationship between the current location and the set destination.

  When performing a route guidance to a destination in a conventional navigation device, the function mainly focuses on how to ensure that the user arrives at the destination. For this reason, for example, immediately before reaching the destination, a process of automatically switching the road map to a detailed scale as in Patent Document 1 is performed. However, if the scale of the road map suddenly changes before arriving at the destination, the user may feel uncomfortable or uncomfortable, and it may be annoying if the road is relatively well known.

  On the other hand, for the user, arrival at the destination is not the final goal but may take the next move afterwards. For example, if you arrive at your destination but the parking lot at your destination is full or there is no parking at your destination, you need to move your car to a parking lot around your destination. In addition, after checking in at a hotel that is the destination and depositing luggage, the user may go out again for shopping, sightseeing, refueling, etc. in the vicinity. Or you may stay at a hotel and shop and refuel the next day. In such a case, in the conventional navigation apparatus, the user has to perform operations such as a peripheral facility search and a destination search, and lacks in operability and convenience.

  An object of the present invention is to solve the above-described conventional problems and to provide a navigation device that automatically displays facilities around the vehicle position by predicting the movement of the user after arriving at the destination.

  The navigation apparatus according to the present invention includes a host vehicle position detection unit that detects the host vehicle position, a route guide unit that guides a route to a set destination, the host vehicle position detection unit, and the route guide unit. Determining means for determining whether or not the vehicle has arrived at the destination; prediction means for predicting whether or not the next movement will be performed after arrival at the destination; and determining means determining that the vehicle has arrived at the destination; and When it is predicted that the next movement will be performed by the predicting means, it has a display means for displaying a road map of a certain scale including the vicinity of the own vehicle position and a facility mark indicating the position of the facility on the road map on the display. .

  Preferably, the predicting means includes restarting the navigation device, scrolling the road map displayed on the display, elapse of a certain time from arrival at the destination, opening / closing of the door of the own vehicle, attachment / detachment of the seat belt, and combinations thereof. When either is present, it is predicted that the next move will take place.

  The navigation device further includes a prediction cancellation unit that cancels the prediction of the next movement by the prediction unit, and when the prediction is canceled, the display unit displays the road map on the display at the original scale. Preferably, the prediction cancellation means cancels the prediction when the road map displayed on the display is scrolled for a predetermined distance or a predetermined time.

  The program according to the present invention displays facility data around the position of the vehicle in the navigation device, the step of determining whether the vehicle has arrived at the set destination, and after the arrival at the destination A step of predicting whether or not the next movement will be performed, and when it is determined that the vehicle will arrive at the destination and the next movement is predicted to be performed, a road map of a certain scale including the vicinity of the vehicle position and the road And displaying a facility mark indicating the location of the facility on the map.

  According to the present invention, when it is predicted that the next movement will be performed after arriving at the destination, a road map of a certain scale including the vicinity of the own vehicle position and a facility mark indicating the location of the facility are automatically displayed. Thus, the user can confirm the position of the next facility to be viewed by looking at the facility mark displayed on the display without searching for neighboring facilities or searching for the next destination after arrival at the destination.

  The best mode for carrying out the present invention will be described in detail with reference to the drawings.

  The storage device 30 stores a program and a database for executing various navigation functions. The database includes map data, facility data, and the like, and the map data includes road (link) data and intersection data related to roads. Link data is data related to the road connecting the intersections, node data indicating the longitude and latitude of the start and end points of the road, data indicating the type of road (national road, general road, prefectural road, etc.), width, regulation ( For example, it includes data such as one-way traffic) and the number of lanes.

  Facility data includes parking lots, convenience stores, hotels, restaurants, gas stations, sightseeing spots, and the like. These facility data include icon display and position data indicating the type or category. For example, if it is a parking lot, the icon display which shows a parking lot is included, and if it is a convenience store, the icon display which shows it is included. The icon display may be a mark that identifies the type of facility, or a mark that can identify an individual specific facility. Further, the facility data may include characters such as the name and type of the facility in addition to the icon display. Such facility data can be displayed on the display as a POI.

  The program memory 60 loads a program stored in the storage device 30. For example, the vehicle position detection program 62 that detects the vehicle position based on position information from the sensor unit 2 or the GPS receiver 12, the route search program 64 that searches for the optimum route to the destination, and the next after arrival at the destination A movement prediction program 66 for predicting whether or not a movement will be performed, and a facility mark automatically displayed on a road map of a certain scale when it is predicted that the next movement will be performed after arrival at the destination It has a facility automatic display program 68 and the like. The control unit 80 controls the operation of each unit according to these programs.

  The data memory 70 includes data 72 from the bus communication control unit 4 that detects the vehicle state, map data 74 that corresponds to the vehicle position read from the storage device 30, facility data 76 that is displayed after arrival at the destination, and the like. Remember.

  Next, the peripheral facility display operation after arrival at the destination in the navigation apparatus of the present embodiment will be described with reference to the flowchart of FIG. The navigation device 6 of this embodiment automatically sets facility data around the vehicle position on a road map of a certain scale when movement to a facility around the destination is predicted after arrival at the set destination. It has a display function.

  First, when a destination is set via the user input interface 20 (step S101), the control unit 80 searches for an optimum route to the destination (step S102). And the control part 80 starts the route guidance to the destination with the start of driving | running | working of the own vehicle (step S103). The control unit 80 detects the vehicle position based on the outputs of the bus interface 10 and the GPS receiver 12, displays a road map around the detected vehicle position on the display, and guides for searching for the vehicle position mark. Display on the route. In addition to the display on the display, the route guidance is also performed by voice guidance by the speaker 42.

  The control unit 80 calculates the distance between the detected vehicle position and the set destination, and determines whether the vehicle has arrived at the destination based on whether the distance is equal to or less than a predetermined value. (Step S104). If it is determined that the host vehicle has arrived at the destination, then the control unit 80 predicts whether or not the next movement will be performed after arrival at the destination (step S105). The control unit 80 monitors the output of the sensor unit 2 and the state of the navigation device. For example, whether the navigation device has been restarted, whether the road map has been scrolled after arriving at the destination, or arrived at the destination. Then, it is determined whether a certain time has passed without the vehicle position being moved, whether the door of the vehicle is opened, whether the seat belt is attached and detached, and whether there is a combination thereof, When these actions are performed, it is predicted that the next movement will be performed.

  When it is predicted that the next movement will be performed after arriving at the destination, the control unit 80 changes the road map around the vehicle position to a certain detailed scale according to the surrounding facility automatic display program 68 and displays it on the road map. A facility mark indicating the type and location of the facility is displayed (step S106). However, if the scale of the road map is a detailed scale, there is no need to change the scale. Further, when the user setting is set not to display the facility mark, the facility mark is forcibly displayed. However, the facility mark may be forcibly not displayed by the user setting.

  FIG. 4 is a display example of a road map when the own vehicle arrives at the destination, and is an example of a wide-scale that displays a range of 500 meters. On the screen, a vehicle position mark M indicating the vehicle position is shown on the guide route 100, and a destination mark 102 indicating the destination is displayed in the vicinity thereof. A large main road is displayed at a wide scale of about 500 meters, but facility marks, narrow streets, and the like indicating facilities around the vehicle position are not displayed.

  As described above, when it is predicted that the vehicle will arrive at the destination and the next movement will be performed, the control unit 80 automatically switches from the map display of FIG. 4 to the road map of the detailed scale as shown in FIG. . As shown in FIG. 5, for example, when a detailed scale for displaying a 25 meter range is reached, various facility marks are displayed together therewith. On the screen, the vehicle position mark M is displayed on the guidance route 100, and facility marks such as a parking lot P, a convenience store C, a restaurant R, a gas stunt G, a hotel H, and other sightseeing spots in the vicinity thereof are displayed. Is displayed.

  By automatically displaying the facility mark on such a detailed scale, the user does not need to newly perform a peripheral facility search or a destination search operation after arriving at the destination, and various types of images displayed on the display are displayed. You can easily check the next destination by looking at the facility mark. In this case, the next destination may be easily set by clicking the displayed facility mark.

  In the above embodiment, 500 meters as the wide scale and 25 meters as the detailed scale are exemplified, but this is an example and the present invention is not limited to this. In short, any map scale that can easily display a POI such as a facility mark can be used. When there are a plurality of detailed scale levels, the user may be able to select an arbitrary detailed scale. Furthermore, the facility mark may be an icon display using a two-dimensional or three-dimensional figure or a photograph, and may further include characters, figures, symbols, and the like.

  Returning to FIG. 3 again, the control unit 80 displays the facility data around the vehicle position on the detailed scale as shown in FIG. 5, and then cancels the display under certain conditions (step S107). For example, when the user sets the facility data as the destination, or when the road map is scrolled for a certain distance or more than a certain time (because it is assumed that there is no user's destination in the display screen), the user instructs the end If there is, return to the original map screen (for example, the wide scale of FIG. 4) (step S108).

  The facility mark displayed after arrival at the destination does not necessarily display all the facility marks, but may display the selected facility mark. For example, only the facility mark set by the user may be displayed. Alternatively, the facility mark may be selected according to the set destination. For example, when a destination is set from a genre, a facility mark corresponding to the genre may be associated in advance, and only the facility mark corresponding to the genre may be displayed. For example, when a destination is set from the genre of tourist destination, the genre of tourist destination is associated with a parking lot and a gas station, and only the facility marks of the parking lot P and the gas station G are displayed as shown in FIG. It may be done.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific embodiments according to the present invention, and various modifications can be made within the scope of the gist of the present invention described in the claims.
