Description

  The present invention relates to a navigation device and a destination list presenting method, and more particularly, navigation having a history search function that makes it possible to search for a facility that has been set as a destination in the past and set it as the current destination. It is suitable for use in an apparatus.

  In general, a navigation device is equipped with a route guidance function for setting a desired destination, searching for a guidance route, and performing travel guidance according to the searched guidance route. Usually, various search functions such as a facility name search, an address search, a telephone number search, and a genre search are prepared as a function for searching for a desired facility as a destination. One of the search functions is a history search function. The history search function allows you to select a desired facility from the list and set it as the current destination by searching for facilities that have been set as destinations in the past and displaying them in a list. It is.

  Conventionally, a technique using this history search function has been proposed. For example, a destination history is stored in the navigation device in association with a toll gate on a toll road used in the past. When the navigation device reads the usage history information (tollgate information, usage details information) of the toll road from the ETC card through the ETC in-vehicle device, the destination history associated with the toll booth of this usage history information is obtained as the destination candidate. (See, for example, paragraph 0060 of Patent Document 1).

  According to the technique described in Patent Document 1, when an ETC card is inserted in an ETC vehicle-mounted device, the destination of a guidance route via a toll road is based on usage history information stored in the ETC card. Facilities that have been set as are presented as destination candidates. In other words, since facilities that have been set as destinations in the past, such as those that are premised on the use of ETC cards (that is, use of toll roads), are presented as candidate destinations at this time. The convenience of the user when setting the destination can be improved.

JP 2007-285552 A

  However, the technique described in Patent Document 1 presents a destination candidate using the use history information stored in the ETC card, and the case where the ETC card is not inserted into the ETC in-vehicle device. No consideration is given.

  That is, when the ETC card is not inserted in the ETC on-board device, when the destination setting menu screen is opened and the history search function is selected, all facilities that have been set as destinations in the past are displayed in a list in that setting order. Is done. For this reason, since a facility in the distance and a facility in the vicinity are displayed together, there is a problem that it takes time to search for and select a desired facility from the list.

  The present invention has been made to solve such problems, and even when a remote facility that assumes the use of an ETC card is set as a destination, the use of the ETC card is not predicated. Even when a relatively nearby facility is set as a destination, the object is to make it easier to find and select a desired facility from a list presented as a destination candidate.

  In order to solve the above-described problems, in the present invention, toll information indicating a facility that has been set as a destination in the past includes a toll road in a guide route set as a route to the destination. Together with identification information indicating whether or not there is a history information storage unit. If it is detected that an ETC card is inserted in the ETC vehicle-mounted device, the facility whose toll road is included in the guidance route according to the identification information is listed at the top of the list. At the same time, a list of candidate destinations in which the facilities indicated that the toll road does not include the toll road in the guide route is generated and presented at the lower part of the list is generated and presented. On the other hand, if the insertion of an ETC card is not detected, the facilities indicated that the toll road is not included in the guide route are listed at the top of the list, and the toll road is included in the guide route. A list of candidate destinations in which the facilities indicated to be present are listed at the bottom of the list is generated and presented.

  According to the present invention configured as described above, when it is desired to set a remote facility assuming the use of an ETC card as a destination, if the ETC card is inserted in the ETC on-board device, the toll road Distant facilities set in the past as destinations for the included guidance route are displayed with higher priority in the destination candidate list. On the other hand, if you want to set a relatively nearby facility that does not assume the use of an ETC card as the destination, if the ETC card is not inserted in the ETC on-board device, The relatively nearby facilities set to are displayed with higher priority in the destination candidate list. This makes it possible to set a far-off facility that presupposes the use of an ETC card as a destination, or to set a relatively close facility that does not presuppose the use of an ETC card as a destination. It is possible to easily find and select a desired facility from the list presented as.

  The timing when the ETC card detection unit 21 notifies the navigation device 100 of the detection signal is the timing when the power of the ETC in-vehicle device 200 is turned on (that is, the timing when the accessory switch (ACC) of the vehicle is switched from OFF to ON), The timing when the ETC card is inserted or removed when the power of the ETC in-vehicle device 200 is on.

  The card insertion detection unit 12 of the navigation device 100 detects whether or not an ETC card is inserted in the ETC in-vehicle device 200 based on the detection signal notified from the ETC card detection unit 21. Then, the history detection unit 10 is notified of the detection result.

  The map data storage unit 1 stores road data representing roads and map data including facility information representing various facilities facing the roads, and is configured by a recording medium such as a hard disk. Although a hard disk is used here as a recording medium for storing map data, other recording media such as a DVD-ROM, a CD-ROM, and a semiconductor memory may be used.

  The road data is data necessary for various processes such as map matching and route search. This road data includes link information related to road links corresponding to individual vectors when the road is divided into a plurality of vectors and node information related to nodes corresponding to both end points of each road link. Contains. Facility information is data including location information and facility name information of various facilities. The facility indicated by this facility information can be set as the destination of the guidance route.

  The current location detection unit 2 detects the current location of the vehicle at predetermined intervals, and includes a self-contained navigation sensor, a GPS receiver, a position calculation CPU, and the like. The self-contained navigation sensor includes a vehicle speed sensor (distance sensor) that outputs a single pulse for each predetermined travel distance to detect the moving distance of the vehicle, and an angular velocity sensor (relative bearing sensor) such as a vibration gyro that detects the rotation angle of the vehicle ). The self-contained navigation sensor detects the relative position and direction of the vehicle using these vehicle speed sensor and angular velocity sensor.

  The position calculation CPU calculates an absolute own vehicle device (estimated vehicle position) and a vehicle direction based on relative position and direction data output from the self-contained navigation sensor. The GPS receiver receives radio waves transmitted from a plurality of GPS satellites by a GPS antenna and performs a three-dimensional positioning process or a two-dimensional positioning process to calculate the absolute position and direction of the vehicle (the vehicle direction is The calculation is based on the current vehicle position and the current vehicle position one sampling time ΔT before).

  The destination setting unit 3 sets, as a destination, a point specified through an operation of the operation unit 110 by the user on the destination setting operation screen displayed on the display unit 120. This destination setting is performed using facility information stored in the map data storage unit 1 or facility information retrieved from the history information storage unit 6 by the history retrieval unit 10 as will be described later.

  The route search unit 4 uses the map data stored in the map data storage unit 1 and has the lowest cost connecting the current location detected by the current location detection unit 2 to the destination set by the destination setting unit 3. Search for a small path. The guide route storage unit 5 temporarily stores the data of the guide route searched by the route search unit 4.

  The history information storage unit 6 identifies facility information representing facilities that have been set as destinations in the past, and indicates whether or not a toll road is included in the guide route set as a route to the destination The information is stored together with the information, and is constituted by a recording medium such as a hard disk. Note that another recording medium such as a semiconductor memory may be used instead of the hard disk. Hereinafter, the facility information and identification information stored in the history information storage unit 6 are collectively referred to as history information.

  FIG. 2 is a diagram illustrating an example of history information stored in the history information storage unit 6. As shown in FIG. 2, the history information of the present embodiment includes facility information indicating facilities that have been set as destinations in the past, and a toll road in the guide route set as a route to the destination. And identification information indicating whether or not The facility information includes, for example, facility name information and position information. The identification information is binary flag information such as “1” when a toll road is included in the guide route, and “0” when the toll road is not included. The history information shown in FIG. 2 is stored in order from the top in the time series of the date and time set as the destination.

  The history recording unit 7 performs a history information recording process on the history information storage unit 6. That is, the history recording unit 7 acquires facility information representing a facility set as a destination from the destination setting unit 3. The history recording unit 7 determines whether or not a toll road is included in the guidance route searched by the route search unit 4 and stored in the guidance route storage unit 5, and identification information is determined according to the determination result. Generate. The history recording unit 7 records the facility information acquired from the destination setting unit 3 and the identification information generated with reference to the guidance route storage unit 5 as a set in the history information storage unit 6.

  The operation reception unit 8 receives various operations on the operation unit 110 by the user. For example, the operation reception unit 8 receives an operation for opening a destination setting menu screen. The operation accepting unit 8 accepts an operation for selecting a history search function from a destination setting menu screen. Furthermore, the operation reception unit 8 receives an operation for setting a specific facility as a destination.

  The menu screen generation unit 9 generates the menu screen and supplies it to the display control unit 11 when the operation reception unit 8 receives an operation for opening the destination setting menu screen. In this case, the display control unit 11 controls the display unit 120 to display the menu screen generated by the menu screen generation unit 9.

  The history search unit 10 is a card when the operation receiving unit 8 receives an operation for selecting the history search function from the destination setting menu screen, or when an ETC card is inserted in the ETC in-vehicle device 200. When it is detected by the insertion detection unit 12, a facility in which facility information is stored in the history information storage unit 6 is searched to generate a list of destination candidates, and the list is supplied to the display control unit 11. In this case, the display control unit 11 controls the display unit 120 to display a list of destination candidates generated by the history search unit 10.

  Specifically, the history search unit 10 operates the operation of the operation unit 110 by the user (the history search function from the destination setting menu screen when the insertion of the ETC card is not detected by the card insertion detection unit 12. The history information storage unit 6 is searched to generate a list of destination candidates.

  At this time, the history search unit 10 places a facility whose toll road does not include a toll road in the guide route according to the identification information stored in the history information storage unit 6, and identifies the facility. A list of destination candidates is generated in which facilities whose toll roads are included in the guidance route are listed below the list. For example, if the history information stored in the history information storage unit 6 is as shown in FIG. 2, the history search unit 10 displays the destination candidates that list each facility in the order shown in FIG. Generate a list.

  Further, the history search unit 10 is notified of the ETC card insertion detection signal from the ETC card detection unit 21 to the card insertion detection unit 12 when the card insertion detection unit 12 detects the insertion of the ETC card. The history information storage unit 6 is searched to generate a list of destination candidates.

  At this time, the history search unit 10 places a facility whose toll road is included in the guide route by the identification information stored in the history information storage unit 6 at the top of the list and identifies the facility. A list of candidate destinations is generated in which the facilities indicated by the information that the toll road does not include a toll road are listed below the list. For example, if the history information stored in the history information storage unit 6 is as shown in FIG. 2, the history search unit 10 displays the destination candidates that list each facility in the order shown in FIG. Generate a list.

  When the operation receiving unit 8 receives an operation for setting a specific facility as a destination from the list of destination candidates, the destination setting unit 3 sets the received facility as a destination. .

  FIG. 4 is a flowchart showing an operation example of the navigation device 100 according to the present embodiment configured as described above. The flowchart shown in FIG. 4 starts when the accessory switch of the vehicle is turned on.

  First, the card insertion detection unit 12 detects whether or not an ETC card is inserted in the ETC in-vehicle device 200 based on the detection signal notified from the ETC card detection unit 21 (step S1). Here, when the insertion of the ETC card is detected, the history search unit 10 searches the history information storage unit 6 and finds a facility whose toll road is included in the guidance route by the identification information. A list of destination candidates preferentially posted at the top of the list is generated (step S2). Then, the display control unit 11 controls the display unit 120 to display the list of destination candidates generated by the history search unit 10 (step S3). Thereafter, the process proceeds to step S9.

  On the other hand, when insertion of an ETC card is not detected in step S1, the operation reception unit 8 determines whether a menu operation of the operation unit 110 related to destination setting has been received (step S4). If the menu operation is not accepted, the process returns to step S1. On the other hand, when a menu operation is accepted, the menu screen generation unit 9 generates a menu screen and supplies it to the display control unit 11. The display control unit 11 controls the display unit 120 to display the menu screen generated by the menu screen generation unit 9 (step S5).

  Subsequently, the operation reception unit 8 determines whether or not the history search function has been selected as a function for searching for a desired facility as a destination from the menu screen displayed on the display unit 120 (step S6). ). When the history search function is selected, the history search unit 10 searches the history information storage unit 6, and places the facilities indicated by the identification information that no toll road is included in the guide route at the top of the list. A list of preferential destinations is generated (step S7). Then, the display control unit 11 controls the display unit 120 to display the list of destination candidates generated by the history search unit 10 (step S8).

  Thereafter, the operation receiving unit 8 determines whether or not an operation for selecting a specific facility has been received from the list of destination candidates displayed on the display unit 120 in Step S3 or Step S8 (Step S9). ). If the operation has not been accepted, the process waits in step S9. On the other hand, when the operation receiving unit 8 receives an operation for selecting a specific facility, the destination setting unit 3 sets the selected specific facility as the purpose (step S10).

  In step S6, the history search function is not selected from the menu screen displayed on the display unit 120, that is, other search functions such as facility name search, address search, telephone number search, and genre search are selected. If it is determined that the destination has been set, the destination setting unit 3 performs destination setting processing according to the search function selected among them (step S11).

  When the destination is set in step S10 or step S11, the route search unit 4 uses the map data stored in the map data storage unit 1 to set the destination from the current location detected by the current location detection unit 2. The route with the lowest cost connecting to the destination set by the unit 3 is searched (step S12). The route search unit 4 stores the searched guide route data in the guide route storage unit 5.

  Finally, the history recording unit 7 includes whether or not a toll road is included in the facility information indicating the facility set as the destination and the guidance route searched by the route search unit 4 and stored in the guidance route storage unit 5. The identification information indicating the set is stored in the history information storage unit 6 (step S13). If the facility to be recorded is already stored in the history information storage unit 6, nothing is recorded.

  As described in detail above, in the present embodiment, whether the toll road is included in the guidance route set as the route to the destination of the facility information representing the facility that has been set as the destination in the past. It is stored in the history information storage unit 6 together with identification information indicating whether or not. If it is detected that an ETC card is inserted in the ETC in-vehicle device 200, the facility whose toll road is included in the guidance route by the identification information is listed at the top of the list. At the same time, a list of destination candidates in which the facilities indicated that the toll road does not include the toll road in the guidance route is listed at the bottom of the list is generated and presented. On the other hand, when insertion of an ETC card is not detected in the ETC in-vehicle device 200, the facility indicating that the toll road is not included in the guide route is posted at the top of the list, and the guide route includes A list of candidate destinations in which facilities indicated to include toll roads are listed at the bottom of the list is generated and presented.

  According to the present embodiment configured as described above, when it is desired to set a remote facility assuming the use of an ETC card as a destination, if the ETC card is inserted in the ETC in-vehicle device 200, a toll road A distant facility set in the past as a destination of a guidance route including is displayed with higher priority in the destination candidate list. On the other hand, when it is desired to set a relatively nearby facility that does not assume the use of an ETC card as a destination, if the ETC card is not inserted into the ETC on-board device 200, the destination of a guidance route that does not include a toll road A relatively nearby facility set in the past is displayed with higher priority in the destination candidate list. This makes it possible to set a far-off facility that presupposes the use of an ETC card as a destination, or to set a relatively close facility that does not presuppose the use of an ETC card as a destination. It is possible to easily find and select a desired facility from the list presented as.

  In the above embodiment, the history search unit 10 immediately searches the history information storage unit 6 to generate a list of candidate destinations when the insertion of the ETC card is detected by the card insertion detection unit 12. However, the present invention is not limited to this. For example, when an operation for selecting a history search function is performed from the destination setting menu screen in a state where an ETC card is inserted in the ETC in-vehicle device 200, the history information storage unit 6 is searched. A list of destination candidates may be generated.

  However, if the destination candidate list is generated immediately when insertion of an ETC card is detected as in the above embodiment, the operation for opening the menu screen and selecting the history search function can be omitted. The destination setting operation can be simplified.

  Note that just because an ETC card is inserted into the ETC in-vehicle device 200, the user does not always search for a destination using the history search function. For example, there are not a few users who always have an ETC card inserted into the ETC in-vehicle device 200 whether the ETC in-vehicle device 200 is turned on or off. In that case, whenever the accessory switch is turned on, the history search function is automatically activated and a list of destination candidates is displayed on the display unit 120, which may be bothersome.

  FIG. 5 is a block diagram showing a modified example of the navigation apparatus according to the present embodiment, and has a function for eliminating the above-described troublesomeness. In FIG. 5, those given the same reference numerals as those shown in FIG. 1 have the same functions, and therefore redundant description is omitted here.

  A navigation device 100 shown in FIG. 5 includes a setting determination unit 13 and a control unit 14 in addition to the functional configuration shown in FIG. The setting determination unit 13 determines whether or not a destination has been set based on a list of destination candidates generated by the history search unit 10 and displayed on the screen by the display control unit 11. For example, when the operation receiving unit 8 receives an operation for setting a specific facility as a destination from the list of destination candidates, the setting determination unit 13 selects the destination based on the list of destination candidates. It is determined that the setting has been made.

  If the setting determination unit 13 determines that the destination setting is not performed from the destination candidate list for a predetermined number of times in spite of the display of the destination candidate list, Thereafter, even when the insertion of the ETC card is detected by the card insertion detection unit 12, the history search unit 10 is controlled so as not to generate a list of destination candidates.

  For example, a cancel button for allowing the user to instruct not to set the destination is added to the list of destination candidates generated by the history search unit 10. Then, when the ETC card is inserted into the ETC in-vehicle device 200, the history search function is automatically activated and the list of destination candidates is displayed on the display unit 120. The determination unit 13 determines that the destination has not been set, and notifies the control unit 14 to that effect. On the other hand, when the destination is set from the list of destination candidates, the control unit 14 is notified accordingly.

  Each time the control unit 14 receives a notification that the cancel button has been operated from the setting determination unit 13, the control unit 14 increases the count value of the number of times the destination is not set based on the destination candidate list by one. To go. On the other hand, when the destination is set from the list of destination candidates, the count value is reset to zero.

  When the count value reaches a predetermined value, the control unit 14 does not generate a list of destination candidates after that even when the insertion of the ETC card is detected by the card insertion detection unit 12. The history search unit 10 is controlled. When an operation for selecting the history search function is performed from the destination setting menu screen, the history search unit 10 is operated as usual.

  In this way, it is possible to simplify the user operation for setting the destination by automatically displaying the list of destination candidates when the insertion of the ETC card is detected. By learning the user operation of the cancel button when displayed, the list of destination candidates can be displayed only when the user desires.

  In addition, each of the above-described embodiments is merely an example of implementation in carrying out the present invention, and the technical scope of the present invention should not be construed in a limited manner. That is, the present invention can be implemented in various forms without departing from the gist or the main features thereof.
