Description

  The present invention relates to a navigation device that is mounted on a vehicle and provides vehicle travel guidance by displaying a map image or the like.

  2. Description of the Related Art Conventionally, there is known a navigation device that stores return points other than home and automatically sets a return point as a destination for route search and guidance (see, for example, Patent Document 1). ). In this navigation device, a return point is selected from the points registered as points.

Japanese Patent No. 3769867

  By the way, in the navigation device disclosed in Patent Document 1 described above, the setting of the return point needs to be performed by selecting from the points that have already been registered, so that an operation for that is necessary and complicated. There was a problem of being. For example, as described in Patent Document 1, when a hotel stays at a hotel for several days on a trip, considering the case where the hotel's parking lot is set as a return point, an operation for preregistering the parking lot of this hotel in advance Then, an operation for selecting the registered point as the return point is required. In addition, when the return point set in this way is no longer necessary (for example, when returning from a trip), this unnecessary return point or registered point is deleted due to the limited number of points registered. If it tries to do so, an operation for that will be required, and the operation will become more complicated when considering from return point registration to deletion.

  The present invention was created in view of the above points, and an object of the present invention is to provide a navigation device that can reduce the complexity of operations when adding or deleting a return point. .

  In order to solve the above-described problem, the navigation device according to the present invention includes a regression point candidate extraction unit that extracts a facility that satisfies a predetermined extraction condition as a regression point candidate from facilities where a vehicle actually stops, and a regression point candidate. Return point candidate storage means for storing the return point candidates extracted by the extraction means, and return point candidate presentation means for reading the return point candidates stored by the return point candidate storage means at a predetermined timing and presenting them to the user. I have. Since the return point candidates are automatically set from the facilities actually visited, it is possible to eliminate troublesome work such as registering the facilities to add the return points.

Further, the return point candidate extracting means described above determines whether or not the facility is to be a return point candidate based on the type of the facility visited and the staying time of the vehicle . Thereby, when staying in a specific facility for a long time, the suitability of the return point can be determined in consideration of the use situation of the facility.

  In addition, the return point candidate extraction means described above determines whether the facility is a return point candidate based on the staying time of the vehicle at the facility when the facility visited is an accommodation facility or a parking lot related to the accommodation facility. It is desirable to determine whether or not. Alternatively, the return point candidate extracting means described above, when the staying time of a vehicle included in a predetermined time frame for a facility that has stopped by exceeds a reference time, sets the facility as a return point candidate based on the type of the facility. It is desirable to determine whether or not to do so. In addition, it is desirable that the above-described return point candidate extracting means sets the stay time as the time during which the power supply of its own device is turned off. Thereby, when staying at an accommodation facility, it becomes possible to set this facility as a return point without performing a special operation.

  Moreover, it is desirable that the above-described return point candidate storage means deletes the stored return point candidate after a predetermined time has elapsed. Thereby, since the return point candidate can be automatically deleted, it is possible to eliminate troublesome work such as performing some operation to delete the unnecessary return point candidate.

Also, route search means for setting the travel route of the vehicle to the destination set by the user by route search processing, and a route for guiding the vehicle travel to the destination along the travel route set by the route search means And a return point candidate presenting means after the vehicle has started traveling from the facility as the return point candidate and after the vehicle has reached the destination, the next destination is not set. In this case, it is desirable to present the return point candidate to the user. As a result, it is possible to specify the original facility again without performing a complicated facility search or the like after leaving the facility where the user visited and using another facility in the vicinity.

Further, the return point candidate presenting means described above is after the vehicle starts running from the facility as the return point candidate , and when the vehicle leaves the facility as the return point candidate for a predetermined time or a predetermined distance. It is desirable to present the return point candidate to the user. As a result, after leaving the facility that has stopped by and leaving the facility, it is possible to identify the facility that has left again without performing a complicated facility search operation or the like.

  Moreover, it is desirable that the return point candidate presenting means described above presents the return point candidate to the user when a presentation instruction is given by the user. Thereby, it is possible to present a return point candidate only when the user desires, and it is possible to prevent useless information presentation to a user who does not desire to present the return point candidate.

  In addition, it is desirable to further include destination setting means for setting the return point candidate presented by the return point candidate presenting means as the destination of the route search process in accordance with a user instruction. Thereby, operation at the time of performing a route search process by using the facility that has stopped by as a destination can be simplified.

  Hereinafter, a navigation device according to an embodiment to which the present invention is applied will be described with reference to the drawings.

  FIG. 1 is a diagram illustrating a configuration of a navigation device according to an embodiment. The navigation device shown in FIG. 1 includes a navigation controller 1, a map data storage device 3, an operation unit 4, a vehicle position detection unit 5, a display device 6, and an audio unit 7. This navigation device is mounted on a vehicle.

  The navigation controller 1 implements various functions such as a map image display operation around the own vehicle position, a facility search operation, and a route search / guidance operation by executing a predetermined operation program using a CPU, ROM, RAM, and the like. . The detailed configuration of the navigation controller 1 will be described later.

  The map data storage device 3 is a storage medium that stores map data necessary for map display, facility search, route search, and the like and a reading device thereof. The map data storage device 3 stores map data in units of rectangular figure leaves divided into appropriate sizes by longitude and latitude. The map data of each leaf can be specified and read by designating the leaf number. The map data storage device 3 is realized by a hard disk device or a semiconductor memory, or by a DVD and its reading device. Further, the map data storage device 3 may be replaced with a communication device to acquire map data from an external map distribution server (not shown).

  The operation unit 4 is for receiving user instructions (operations), and includes various operation buttons and operation knobs. In addition, the operation unit 4 includes a touch panel attached to the screen of the display device 6, and the user can directly perform an operation instruction by pointing a part on the screen with a finger or the like. Yes. The vehicle position detection unit 5 includes, for example, a GPS receiver, an orientation sensor, a distance sensor, and the like, detects the vehicle position (longitude, latitude) at a predetermined timing, and outputs a detection result.

  The display device 6 is composed of, for example, an LCD (liquid crystal display device), and is obtained by a map image around the vehicle position, an intersection guide image, or a facility search based on the video signal output from the navigation controller 1. A search result image including the facility and the surrounding parking lot is displayed. The audio unit 7 outputs a guidance voice or the like generated based on the voice signal input from the navigation controller 1 into the vehicle interior.

  Next, a detailed configuration of the navigation controller 1 will be described. A navigation controller 1 shown in FIG. 1 includes a map buffer 10, a map readout control unit 12, a map drawing unit 14, a vehicle position calculation unit 20, a route search processing unit 22, a route guidance processing unit 24, a facility search unit 30, and a destination setting. The unit 32 includes a return point candidate extraction unit 40, a return point candidate storage unit 44, a point storage unit 46, a return point candidate presentation unit 48, an input processing unit 50, and a display processing unit 60.

  The map buffer 10 temporarily stores map data read from the map data storage device 3. The map reading control unit 12 sends a request for reading a predetermined range of map data in accordance with the vehicle position calculated by the vehicle position calculating unit 20 and the position designated by the user by operating the operation unit 4. Output to. Based on the map data stored in the map buffer 10, the map drawing unit 14 performs drawing processing necessary for displaying a map image on the display device 6 to create map image drawing data.

  The vehicle position calculation unit 20 calculates the vehicle position based on the detection data output from the vehicle position detection unit 5, and if the calculated vehicle position is not on the road of the map data, the vehicle position is calculated. Perform map matching processing to correct.

  The route search processing unit 22 performs route search processing to search for a travel route (guidance route) that connects the departure point and the destination according to a predetermined search condition. The route guidance processing unit 24 displays the guidance route obtained by the route search processing by the route search processing unit 22 so as to be superimposed on the map, and creates guidance route drawing data for displaying an enlarged view of the right / left turn intersection. At the same time, an audio signal such as intersection guidance necessary for guiding the vehicle along the guidance route is generated.

  The facility search unit 30 searches for a facility that satisfies the search conditions set using the operation unit 4. For example, as a search condition, there are a case where a facility genre is specified and candidate facilities are narrowed down, or a case where a telephone number or an address is specified to narrow down facilities. After a specific facility is extracted in this way, a route search process using this facility as a destination, a display of a map around the facility and detailed information, and the like are performed.

  The destination setting unit 32 sets a destination necessary for the route search processing performed by the route search processing unit 22. For example, when setting the facility extracted by the search by the facility search unit 30 as the destination, or when setting the point on the map image directly designated by the user by operating the operation unit 4 as the destination, For example, a specific facility as a return point candidate that is automatically set may be set as a destination. Details of the automatic setting of the return point candidate will be described later.

  The return point candidate extraction unit 40 extracts, as a return point candidate, a facility that satisfies a predetermined extraction condition from the facilities where the vehicle actually stops. Specifically, it is conceivable to consider “type of facility visited” and “time spent on vehicle” as extraction conditions. For example, in the case where the visited facility is an accommodation facility or a surrounding parking lot corresponding to the accommodation facility, it is determined whether or not the facility is a return point candidate based on the staying time of the vehicle at the facility. Alternatively, when the staying time of a vehicle included in a predetermined time frame for a facility that has stopped by exceeds a reference time, whether or not the facility is a candidate for a return point is determined based on the type of the facility.

  In order to make these determinations, the regression point candidate extraction unit 40 includes a facility identification unit 41 and a stay time calculation unit 42. The facility specifying unit 41 specifies a facility corresponding to the vehicle position when the navigation apparatus is powered on. This facility is specified using the map data read from the map data storage device 3 and stored in the map buffer 10. The stay time calculation unit 42 calculates the stay time of the vehicle at the vehicle position based on the power-off / turn-on time when the navigation device is turned on. For example, in the time frame from 7:00 pm on the previous day to 10:00 am on the following day, the time from when the power is turned off until the next time the power is turned on is calculated as the vehicle stay time. As a premise of this calculation, it is assumed that the time when the power of the navigation device is turned off (the time when the accessory switch of the vehicle is turned off) is recorded and held in a nonvolatile memory or the like when the power is turned off.

  The return point candidate storage unit 44 stores the return point candidates extracted by the return point candidate extraction unit 40 by storing them in the point storage unit 46. The return point candidate storage unit 44 deletes the return point candidate stored in the point storage unit 46 after a predetermined time has elapsed. For example, it is possible to delete when a certain time has elapsed after storage, or when deleting at a certain time such as the storage date or the next day.

  The point storage unit 46 stores the return point candidate extracted by the return point candidate extraction unit 40, the home point specified by the user through a predetermined operation, and the like.

  The return point candidate presenting unit 48 reads out the return point candidates stored in the point storage unit 46 at a predetermined timing after the vehicle starts running from the facility where the stop is made, and presents it to the user.

  The input processing unit 50 outputs commands for performing operations corresponding to various operation instructions input from the operation unit 4 to each unit in the navigation controller 1.

  The display processing unit 60 receives the map image drawing data created by the map drawing unit 14 and displays a predetermined range of map images on the screen of the display device 6 based on the drawing data. In addition, when the travel route set by the route search processing unit 22, the facility obtained by the search by the facility search unit 30, or the drawing data indicating the content presented by the return point candidate presentation unit 48 are input, the display processing unit 60 displays these drawing data on the screen of the display device 6 so as to overlap the map image.

  The above described return point candidate extraction unit 40 is a return point candidate extraction unit, the return point storage unit 44, the point storage unit 46 is a return point candidate storage unit, and the return point candidate presentation unit 48 is a return point candidate presentation unit. The processing unit 22 corresponds to the route searching unit, the route guidance processing unit 24 corresponds to the route guiding unit, and the destination setting unit 32 corresponds to the destination setting unit.

  The navigation device of the present embodiment has such a configuration, and next, an operation relating to a return point candidate will be described. 2 and 3 are flowcharts showing an operation procedure for automatically storing and using the return point candidates.

  When the navigation apparatus is powered on, the facility identification unit 41 identifies a facility corresponding to the vehicle position at the time of power activation (step 100). Next, the regression point candidate extraction unit 40 determines whether or not the identified facility corresponds to a facility that is an extraction target as a regression point candidate (step 102). In the present embodiment, “accommodation facilities” such as inns and hotels or “peripheral parking lots corresponding to accommodation facilities” are assumed as the facilities to be extracted, and whether or not the facilities identified in step 100 correspond to these facilities. Is determined. If the identified facility does not correspond to the extraction target facility, a negative determination is made in the determination of step 102, and a series of processing relating to the regression point candidate is terminated.

  If the identified facility corresponds to the extraction target facility, an affirmative determination is made in the determination of step 102. Next, the stay time calculation unit 42 calculates the stay time of the vehicle included in the predetermined time frame based on the power off / on time (step 104). As described above, for example, in the time frame from 7:00 pm on the previous day to 10:00 am on the next day, the time from when the power is turned off until the next time the power is turned on is calculated as the vehicle stay time. The Next, the regression point candidate extraction unit 40 determines whether or not the calculated stay time is equal to or longer than a reference time (step 106). For example, “6 hours” is set as the reference time, and it is determined whether or not the power of the navigation apparatus has been turned off for 6 hours or more between 7 pm on the previous day and 10:00 am on the next day. If the staying time is less than the reference time, a negative determination is made in the determination in step 106, and the series of processing relating to the return point candidate is terminated.

  If the staying time is equal to or longer than the reference time, an affirmative determination is made in step 106. In the above description, the facility determination (step 102) is performed first, and the stay time determination (steps 104 and 106) is performed later. However, the order may be changed.

  Next, the regression point candidate extraction unit 40 extracts the facility identified in Step 100 as a regression point candidate (Step 108). The return point candidate storage unit 44 stores the extracted return point candidate by storing it in the point storage unit 46 (step 110).

  Next, the return point candidate presentation unit 48 determines whether or not the destination is set after leaving the return point candidate facility (step 112). In this embodiment, when staying overnight at a tourist inn or the like, it is assumed that the travel route from the inn to the surrounding tourist facility is determined by route search processing. When you stop by one or more tourist facilities in this way, each tourist facility is set as a destination and the route search process is performed, but when you leave the last visited tourist facility Next, it is assumed that the destination is not set. In the determination in step 112, it is determined whether or not the next destination is set when the facility set as the destination for route search departs. If the next destination is set, an affirmative determination is made in the determination of step 112, and this determination is repeated.

  On the other hand, if the next destination is not set, a negative determination is made in step 112. Next, the return point candidate presentation unit 48 performs a predetermined guidance display for calling and using the return point candidate stored in step 110 (step 114). For example, as shown in FIG. 4, a “return setting” button is displayed at the upper right of the screen.

  Next, the return point candidate presentation unit 48 determines whether or not the “return setting” button used for the guidance display has been indicated by the user (step 116). If not, a negative determination is made, and the process returns to step 114 and the guidance display is repeated.

  In addition, when the “return setting” button is indicated by the user, an affirmative determination is made in the determination of step 116. Next, the return point candidate presentation unit 48 displays the return point candidates (step 118). For example, as shown in FIG. 5, two character strings of “home” as a return place and “Shinagawa xx hotel” as a return point candidate read from the point storage unit 46 are included in the upper right of the screen. A button is displayed.

  Next, the destination setting unit 32 determines whether or not the “Shinagawa xx hotel” button is pointed and selected by the user (step 120). If the “Shinagawa xx hotel” button is selected, an affirmative determination is made, and “Shinagawa xx hotel” as a return point candidate is set as the destination in the route search process (step 122). Thereafter, route search processing by the route search processing unit 22 with “Shinagawa xx hotel” as the destination, and route guidance processing by the route guidance processing unit 24 that guides the driving of the vehicle to “Shinagawa xx hotel” are performed.

  If the “Shinagawa xx hotel” button is not selected by the user, a negative determination is made in the determination of step 120. Next, the destination setting unit 32 determines whether or not the “home” button is pointed and selected by the user (step 124). If the “home” button is not selected, a negative determination is made, and the process returns to step 118 to continue displaying the “Shinagawa xx hotel” button and the like. If the “home” button is selected, an affirmative determination is made in the determination in step 124, and “home” is set as the destination in the route search process (step 126). Thereafter, route search processing by the route search processing unit 22 with “home” as the destination, and route guidance processing by the route guidance processing unit 24 that guides driving of the vehicle to “home” are performed.

  As described above, in the navigation device of the present embodiment, the return point candidates are automatically set from the facilities actually visited, so there is no troublesome task such as registering the facilities to add the return points. can do.

  Also, based on the type of facility you visited and the duration of the vehicle, you can determine whether the facility is a candidate for a return point. Thus, the suitability of the return point can be determined. In addition, when the facility visited is an accommodation facility or a parking lot related to the accommodation facility, it is determined whether or not the facility is a return point candidate based on the staying time of the vehicle at the facility. Alternatively, when the staying time of a vehicle included in a predetermined time frame exceeds the reference time for the facility that visited, it is determined whether or not the facility is a return point candidate based on the type of the facility. . In particular, the staying time is the time during which the power supply of the own device is turned off. Thereby, when staying at an accommodation facility, it becomes possible to set this facility as a return point without performing a special operation.

  In addition, by automatically deleting the return point candidates after a predetermined time has elapsed, it is possible to eliminate troublesome work such as performing some operation to delete unnecessary return point candidates.

  In addition, by presenting the return point candidate to the user at a predetermined timing after the vehicle has started running from the facility where the stop was started, this facility should be set as the return point candidate after leaving the actually stopped facility Is possible. In particular, after the vehicle has arrived at the destination and the next destination has not been set, by presenting the return point candidate to the user, it is possible to leave the facility where the stop was placed and After the facility is used, the original facility can be identified again without performing a complicated facility search operation or the like.

  In addition, according to the user's instruction, the proposed return point candidate can be set as the destination of the route search processing, so that the operation when performing the route search processing with the facility where you stopped is simplified. It becomes possible.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, in the above-described embodiment, the staying time is from when the power of the navigation device is turned off to when it is turned on, but the vehicle is continuously stopped or parked at the same position regardless of whether the power is turned off or on. The staying time may be the staying time.

  In the above-described embodiment, the extraction condition for extracting the return point candidate is “accommodation facility” or “peripheral parking lot corresponding to the accommodation facility” from 7 pm on the previous day to 10 am on the next day. In the time frame, the time from when the power is turned off until the next time when the power is turned on is 6 hours or more. However, this extraction condition can be changed as appropriate. For example, a parking lot other than “a surrounding parking lot corresponding to the accommodation facility” may be included. Alternatively, the stay time may be calculated without considering the “time frame” from 7:00 pm on the previous day to 10:00 am on the next day.

  Further, in the above-described embodiment, the “return setting” button shown in FIG. 4 is displayed when the destination is not set after leaving the return point candidate facility. When the predetermined time has elapsed or the vehicle has traveled a predetermined distance after the departure, this “return setting” button may be displayed. As a result, after leaving the facility that has stopped by and leaving the facility, it is possible to identify the facility that has left again without performing a complicated facility search operation or the like.

  Or you may make it display this "return setting" button at the timing when the presentation instruction | indication by the user was performed. Thereby, it is possible to present a return point candidate only when the user desires, and it is possible to prevent useless information presentation to a user who does not desire to present the return point candidate.

  Further, in the above-described embodiment, the “return setting” button shown in FIG. 4 is displayed, and after this is pointed by the user, “Shinagawa xx hotel” and “home” as return point candidates shown in FIG. However, without displaying the “return setting” button shown in FIG. 4, “Shinagawa xx hotel” as a return point candidate shown in FIG. 5 is immediately displayed. You may do it.

  Further, the “return setting” button shown in FIG. 4 may be displayed, and after this is pointed by the user, the “return place selection” screen shown in FIG. 6 may be displayed. This screen includes two options of “Shinagawa xx hotel” and “home” as return point candidates, and the user can point to one of the options and set the destination. If this selection operation is not performed within a predetermined time, the display shown in FIG. 5 may be performed.

  Further, in the above-described embodiment, when “Shinagawa xx hotel” as the return point candidate shown in FIG. 5 is indicated by the user, this “Shinagawa xx hotel” is set as the destination of the route search process. However, the “Shinagawa xx hotel” may be optionally registered as a spot.

  As described above, according to the present invention, the return point candidate is automatically set from the facilities actually visited, so that the troublesome task of registering the facility to add the return point is eliminated. be able to.
