Description

  The present invention relates to a navigation device and a navigation device program for guiding a route to a parking lot or a boarding / alighting point associated with a facility.

Conventionally, when a vast station is designated as a destination facility, a technology is known in which a user selects a main getting-on / off point such as the north exit or the south exit and guides a route to the selected getting-on / off point (for example, Patent Document) 1).
JP 2002-298296 A

  However, for some reason (for example, the point is crowded or the point has passed the point), it may be necessary to make another boarding / exiting point as the destination. In such a case, according to the technique as described above, it is necessary for the user to determine and specify the getting-on / off point again. It is complicated for the user that such a determination and designation work burden occurs after the destination needs to be changed. If the user is driving the vehicle, the concentration on the driving operation may be hindered.

  In view of the above points, an object of the present invention is to reduce a user's work burden caused when a destination is changed in the technology of a navigation apparatus that guides a user using a boarding / alighting point associated with a facility or a parking lot as a destination.

In order to achieve the above object, the present invention is characterized in that a navigation device having a route guidance function for guiding a route to a predetermined destination comprises a parking lot or a boarding / alighting point attached to a facility designated by a user. The group is displayed so that a plurality of points in the group can be designated as destination candidates by the user, and the plurality of points designated by the user are recorded as destination candidates on the storage medium. Guidance using the route guidance function with one of the destination candidates as a destination, and displaying a point other than the destination among the plurality of destination candidates during the route guidance. When there is an instruction of the destination user changes, followed destination automatically changes the destination other than the current destination among the plurality of potential destination, and the change The target area is that the guide to using the route guidance function.

Here, the group consisting of parking lot points or getting-on / off points is a group consisting of N parking lots and M parking lots. Here, the values of N and M are each an integer equal to or greater than zero, and any combination may be used as long as N + M is equal to or greater than 2.
When the navigation apparatus that records a plurality of destination candidates associated with the designated facility is operated, when the user gives an instruction to change when the destination is changed, the navigation apparatus substitutes an alternative destination. Select from the destination candidates that recorded the location. Therefore, it is not necessary for the user to re-select the destination from points that can be all destinations, and as a result, the work burden on the user that occurs when the destination is changed is reduced.

  Further, the navigation device changes the destination to a destination other than the current destination among the plurality of destination candidates based on the fact that the current position of the navigation device has passed the current destination. The destination may be guided using the route guidance function. In this way, when the user passes the current destination, the navigation device automatically selects the alternative destination recorded from the destination candidates, so when the destination is changed The resulting work burden on the user is further reduced.

  The features of the present invention can be understood not only as a navigation device but also as a program for the navigation device.

(First embodiment)
Hereinafter, an embodiment of the present invention will be described. FIG. 1 shows a hardware configuration of a vehicle navigation apparatus 1 according to this embodiment. The vehicle navigation device 1 includes a position detector 11, an image display device 12, an operation switch group 13, a speaker 14, a traffic information receiver 15, a map data acquisition unit 16, and a control circuit 17.

The current position and direction of the vehicle based on the characteristics of each of these sensors. , And information for specifying the speed is output to the control circuit 17.

  The image display device 12 displays a video based on the video signal output from the control circuit 17 to the user. Examples of the display image include a map centering on the current location.

  The operation switch group 13 includes a plurality of mechanical switches provided in the vehicle navigation device 1 and an input device such as a touch panel provided so as to overlap the display surface of the image display device 12. A signal based on the touch is output to the control circuit 17.

  The traffic information receiver 15 receives information such as traffic congestion information on roads, traffic regulation information, parking lot congestion, waiting time for entrance to the parking lot, etc. wirelessly transmitted from FM radio stations or roadside equipment installed along the road. It is a wireless receiver that receives and outputs to the control circuit 17.

  The map data acquisition unit 16 includes a nonvolatile storage medium such as a DVD, a CD, and an HDD, and a device that reads data (and writes data if possible) to the storage medium. The storage medium stores a program executed by the control circuit 17, map data for route guidance, and the like.

  The map data has road data and facility data. The road data includes link position information, type information, node position information, type information, information on connection relations between nodes and links, and the like. The facility data has a plurality of records for each facility, and each record has data indicating name information, location information, facility type information, associated point information, and the like of the target facility.

  The accompanying point information includes information such as a point type, a location, and a name for each of one or a plurality of parking lots and one or a plurality of getting-on / off points associated with the corresponding facility.

  A control circuit (corresponding to a computer) 17 is a microcomputer having a CPU, RAM, ROM, I / O and the like. The CPU executes a program for the operation of the vehicle navigation device 1 read from the ROM or the map data acquisition unit 16, reads information from the RAM, the ROM, and the map data acquisition unit 16 when executing the program. Information is written to the storage medium of the map data acquisition unit 16 (if possible), and signals are exchanged with the position detector 11, the image display device 12, the operation switch group 13, and the speaker 14.

  Specific processing performed by the control circuit 17 executing the program includes current position specifying processing, destination setting processing, guidance route calculation processing, route guidance processing, and the like. The current position specifying process is a process for specifying the current position and direction of the vehicle based on a signal from the position detector 11 using a known technique such as map matching.

  The destination setting process is a process of determining a destination for the guidance route calculation process and the route guidance process based on the designation by the user. Details of the destination setting process will be described later. The guide route calculation process is a process for calculating an optimum guide route to the destination determined by the destination setting process.

  In the route guidance process, map data is read from the map data acquisition unit 16 and an image in which the calculated guidance route, destination, current position, etc. are overlaid on the map indicated by the map data is output to the image display device 12. This is a process in which the speaker 14 outputs a guidance voice signal instructing a right turn, a left turn, etc., when necessary, such as when the host vehicle reaches before the guidance intersection.

  Hereinafter, the operation of the vehicle navigation device 1 having the above-described configuration will be described. For this explanation, a situation as shown in FIG. 2 is assumed. In FIG. 2, the vehicle on which the vehicle navigation device 1 is mounted is at a position 21 near the home 22, and the driver is going to drive to the shopping center 23 by driving the vehicle. The shopping center 23 is laid with three dedicated parking lots P1, P2, and P3.

  At this time, the driver inputs the shopping center 23 as a target facility by executing a predetermined operation on the operation switch group 13 of the vehicle navigation apparatus 1. The control circuit 17 starts executing the detailed setting process for the destination based on the input of the target facility during the execution of the destination setting process. First, as illustrated in FIG. The image display device 12 is caused to display the display 30 that prompts the user to select a plurality of parking lots associated with the target facility, and then the execution of the program 100 shown in FIG. 4 is started. The screen display 30 includes switch images 31 to 36 that can be activated by the user using the operation switch group 13.

  In the execution of the program 100, the control circuit 17 waits until either the return switch 36 (step 110) or the setting completion switch 35 (step 120) is activated by the user. While waiting, either one of the switches 31 to 33 for designating the parking lots P1, P2, and P3 and the switch 34 for designating all the parking lots P1, P2, and P3 are activated. Each time an interrupt processing program 200 as shown in FIG. 5 is executed, a point corresponding to the activated button (that is, a parking lot in this embodiment) is additionally stored in a storage medium such as a RAM. For example, when the parking lot P1 designation switch 31 is activated, the parking lot P1 is recorded, and when the parking lot P2 designation switch 32 is subsequently activated, the parking lot P2 is additionally recorded. At this time, as shown in FIG. 6, the control circuit 17 may control the image display device 12 so as to highlight all the switches activated during standby among the switches 31 to 34.

  When the switch 36 that returns to standby is activated (step 110), the control circuit 17 discards the record of the point and ends the execution of the program 100, and displays the display content of the image display device 12 before the screen display 30. Return to the screen display (for example, a display prompting the user to select a target facility).

  Further, when the setting completion switch 35 is activated during standby (step 120), the control circuit 17 determines whether or not a point has been recorded (step 130). Is set as a destination candidate (step 140). When the point is not recorded and after step 140, the execution of the program 100 is terminated and the display content of the image display device 12 is returned to the screen display displayed before the screen display 30.

  By the operation of the control circuit 17 as described above, the vehicle navigation device 1 stores a plurality of points designated by the user as destination candidates among a group of parking lots attached to the facility designated by the user. Can be recorded.

  When the destination candidates are set, the control circuit 17 subsequently executes the destination control program 300 as shown in FIG. 7. In the execution, first, is there a plurality of set destination candidates? It is determined whether or not (step 310), and if it is not plural but one, the point is determined as the destination (step 320), and then the execution of the program 300 is terminated. When the destination is determined, guidance route calculation processing and route guidance processing for the destination are executed.

  If it is determined that there are a plurality of set destination candidates (step 310), then the nearest destination among the plurality of destination candidates (ie, the closest to the current position of the host vehicle) is selected. The destination is determined (step 330).

  When the destination is determined, the control circuit 17 executes a guidance route calculation process and a route guidance process for the destination in parallel with the processing of the program 300. An example of a display screen displayed by the image display device 12 during execution of the route guidance process is shown in FIG. As described above, the control circuit 17 controls the image display device 12 to highlight the current position 21, the destination (the parking lot P2 in the example of FIG. 8), the guide route 24 to the destination, and the like on the map image. To do. At this time, following step 330, the control circuit 17 controls the image display device 12 so as to highlight a point of a destination candidate (parking lot P1 in the example of FIG. 8) other than the point determined as the destination. (Step 340). The expression form of highlighting of the current destination and the expression form of highlighting of other destination candidates may be different so that they can be distinguished from each other. As a method of changing the expression form of the highlight display, there is a method of making the color scheme, tone, presence / absence of blinking, etc. different. In step 340, the image display device 12 is further controlled so that switches 25 and 26 that can be selected by the user as shown in FIG. 8 are superimposed on the map image.

  Thereafter, the control circuit 17 suspends the processing of the program 300 until the user activates the destination change switch 25 (step 350) or the guidance end switch 26 (step 370).

  For example, the driver may recognize that the destination parking lot is full based on the information received by the traffic information receiver 15 as a situation where the destination change switch 25 is activated. is there. However, even if there is a situation where it is difficult to use the parking lot, such as when the driver is full, the driver must activate the destination change switch 25 if he / she wants to use the parking lot even after the difficulty is resolved. That's fine. In such a case, route guidance to the current destination continues. In order to support such a driver's judgment, the control circuit 17 may acquire the entrance waiting time of the destination parking lot from the traffic information receiver 15 and display it on the image display device 12. .

  When the destination change switch 25 is activated (step 350), one of the set destination candidates that is not the current destination is selected and the selected destination is selected. The destination is determined to replace the previous destination (step 360). The destination candidate to be selected is the destination candidate closest to the current position among the destination candidates that are not the current destination. When the destination is determined, the control circuit 17 executes guide route calculation processing and route guidance processing for the destination in parallel with the processing of the program 300. Further, step 340 is executed again, and the destination candidate points other than the point determined as the new destination are highlighted.

  When the guidance end switch 26 is activated by the user (step 370), the control circuit 17 ends the execution of the program 100. Further, the control circuit 17 ends the route guidance process.

  By the operation as described above, when the target navigation facility is input, the vehicular navigation device 1 is routed to a point selected by the user among the facilities such as a parking lot associated with the target facility. Since the guidance is performed, the driver's intention is more reflected in the route guidance function of the vehicle navigation device 1.

  In addition, the vehicle navigation apparatus 1 records a plurality of points designated by the user as destination candidates among a group of parking lots attached to the facility designated by the user (see programs 100 and 200), and The route guidance function is used to guide one of the plurality of recorded destination candidates as a destination (see step 330), and based on the instruction to change the destination by the user (step 350). The destination is changed to a destination other than the current destination among the plurality of destination candidates (see step 360), and the changed destination is guided using the route guidance function.

  By operating the vehicular navigation apparatus 1 that records a plurality of destination candidates associated with the designated facility, the user simply gives an instruction to change when changing the destination. Choose from destination candidates that record alternative destinations. Therefore, it is not necessary for the user to re-select the destination from points that can be all destinations, and as a result, the work burden on the user that occurs when the destination is changed is reduced. That is, by storing a plurality of points as destination candidates, it is possible to change from the initial destination to another destination by a simple operation according to the driver's intention. For example, if the driver wants to change the destination when the host vehicle reaches the vicinity of the target facility, the driver only has to activate the destination change switch 25 in FIG. Can be changed.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. The present embodiment is different from the first embodiment in that the control circuit 17 of the present embodiment executes a program 300 ′ shown in FIG. 9 instead of the program 300 shown in FIG. Note that steps denoted by the same reference numerals in FIGS. 7 and 9 perform the same processing.

  In the following, the different parts of the processing by the program 300 and the processing by the program 300 ′ will be mainly described. In the execution of the program 300 ′, after step 340, the control circuit 17 causes the vehicle to pass the current destination (step 345), the destination change switch 25 is activated (step 350), and guidance. Until the end switch 26 is activated (step 370), the processing of the program 300 'is suspended.

  In addition, as a method for determining that the host vehicle has passed the current destination, for example, a linear distance between the current position of the host vehicle and the current position of the current destination is a predetermined proximity reference distance (for example, 10 meters). It may be determined that the vehicle has passed the destination only when the linear distance exceeds the predetermined proximity reference distance. Further, for example, the linear distance between the current position of the host vehicle and the current position of the current destination is less than a predetermined proximity reference distance, and thereafter, the linear distance is longer than a predetermined deviation reference distance (longer than the proximity reference distance: For example, it may be determined that the vehicle has passed the destination only when the distance exceeds 30 meters.

  When the host vehicle passes the current destination (step 345), the control circuit 17 subsequently selects one of the set destination candidates from the destination candidates that are not the current destination, and the selected The destination is determined as a destination to replace the previous destination (step 360), then route guidance for the destination is started, and step 340 is executed again.

  When the destination change switch 25 is pressed, the control circuit 17 causes the user to select one of the set destination candidates that are not the current destination and the selected destination candidate. The destination candidate is determined as a new destination (step 365), then route guidance for the destination is started, and step 340 is executed again. At this time, in order to prompt the user to select, a plurality of switch images that can select each of the destination candidates may be displayed on the image display device 12.

  Thus, if the user gives an instruction to change when the destination is changed (see step 350), the vehicle navigation device 1 selects an alternative destination from the recorded destination candidates. (See step 365), route guidance to the selected destination is performed. Therefore, it is not necessary for the user to re-select the destination from points that can be all destinations, and as a result, the work burden on the user that occurs when the destination is changed is reduced.

  Further, the vehicle navigation device 1 determines that the destination is a destination other than the current destination among a plurality of destination candidates based on the current position of the host vehicle passing the current destination (see step 345). The destination is changed automatically (see step 360), and the changed destination is guided using the route guidance function. In this way, when the user has passed the current destination, the vehicle navigation device 1 automatically selects the destination from the alternative destination recorded. The work burden on the user that occurs when the change is made is further reduced.

In a memory card attached by the user, facility data including an accompanying facility information setting updated in advance by a dedicated tool is stored in a predetermined format.

  In executing the program 400, the control circuit 17 first determines whether or not to update the facility data (step 410), and continues the processing of the program 400 only when it is determined to update. This determination may be made according to whether or not the facility data is included in the inserted memory card, or may be made according to the user's update permission or non-permission operation.

  If it is determined that the update is to be performed, the image display device 12 is then caused to display a warning not to remove the memory card during the update (step 420). Then, the contents of the new facility data in the memory card are reflected in the facility data in the map data acquisition unit 16 (step 430). When the update is completed, the image display device 12 is displayed that the memory card can be removed (step 440). In addition, since the memory card is not used only for updating the facility information, it is natural that the memory card is operated according to other procedures corresponding to other uses of the memory card.
