When the display position of the azimuth magnetic needle icon is touched, the control unit 13 changes the display mode of the map to north-up (a display mode in which the upper direction of the display unit 4 is displayed as north) and the heading-up (up to the top of the display unit 4). (A display mode in which the direction is displayed as the traveling direction).

  The map scale display section 32 displays the scale of the displayed map. Each time the display position of the map scale display section is touched, the scale of the map is sequentially switched. The preset call button 33 is a button for displaying a preset button 43 described later. The preset call button 33 may be always displayed on the navigation screen, or may be displayed only when the guidance function is used. The own vehicle speed display unit 34 displays the traveling speed of the vehicle.

  The vehicle position mark 35 is displayed at a position corresponding to the current position (own vehicle position) on the map. The vehicle position mark 35 may be, for example, an icon of an isosceles triangle. The display position of the icon may indicate the current position, and the traveling direction may be indicated by the direction of the apex angle of the isosceles triangle. At the lower end of the navigation screen, a menu bar 36 is displayed. The menu bar 36 displays, for example, the address of the vehicle position, the road name, the latitude and longitude, and the like. When the display position of the menu bar 36 is touched, a navigation menu screen shown in FIG. 6 is displayed. The navigation menu screen is a screen for selecting and activating various sub functions in the navigation function. On the navigation menu screen, sub-functions such as “search”, “edit route”, “switch to general road”, “go home”, “register / edit”, “start / stop GPS reception”, “setting”, And an icon for selecting “stop guidance” is displayed, and a current position button 37 for returning to the navigation screen, an end button 38 for returning to the main menu screen, and a Back button 39 for returning to the previous screen are displayed. Is displayed. Then, when the user touches the display position of the icon corresponding to each sub-function, the corresponding sub-function is activated.

  “Search” is a sub-function for searching for and setting a destination. "Route editing" is a sub-function for editing the route set by the guidance function when the guidance function is used. If the guidance function is not used, “edit route” is not selectable. “Switch to general road” is a sub-function for switching the current position from on the expressway to a general road, and is used as necessary when the expressway and the general road are provided side by side. "Return to home" is a sub-function for setting the destination of the guidance function to a home registered in advance. “Registration / editing” is a sub-function for registering a home or other desired point in the database 14 or editing an existing registered point. “GPS reception start / stop” is a sub-function for starting or stopping GPS signal reception by the GPS receiver 11. “Setting” is a sub-function for performing various settings. “Guidance cancellation” is a sub-function for canceling the guidance function. If the guidance function is not used, “cancel guidance” cannot be selected.

  Next, an example of a procedure for setting a destination when the navigation function is activated and using the guidance function will be described. When "search" is selected on the navigation menu screen, the control unit 13 displays the search menu screen shown in FIG. On the search menu screen, a destination search method provided in the navigation device 1 is presented in a selectable manner. On the search menu screen, for example, an icon indicating a search method such as a free word search, an address search, a facility search, a telephone number search, a peripheral facility search, a current location button 37 for returning to the navigation screen, and for returning to the previous screen. Back button 39 is displayed.

  When the user touches the icon, the destination can be searched by the search method corresponding to the touched icon. For example, in a free word search, a destination can be searched using an arbitrary keyword. In the address search, the telephone number search, and the facility search, the destination can be searched by the address, telephone number, and name of the facility to be set as the destination. In the peripheral facility search, a destination can be searched from facilities located around the current position. This peripheral facility search will be described later in detail. In order to realize a search based on these various types of information, the database 14 of the present embodiment stores the names of facilities such as houses, companies, stores, etc., telephone numbers of the facilities, addresses, location information of the addresses, and classifications of the facilities. And related information is stored.

  In addition, besides setting the destination from the "search" sub-function, scroll the map on the navigation screen to display the destination in the map, and display the displayed position in the guide function destination (end point of search) Can also be set as

  When the destination is set, the control unit 13 acquires the position information corresponding to the destination from the database 14. Then, the obtained position information is set as the position information of the destination, and the recommended route from the current position to the destination is obtained based on the road network information stored in the database 14. As a method of calculating the recommended route, a known method such as the Dijkstra method can be used.

  The control unit 13 displays the calculated recommended route together with the surrounding map and displays the route from the current position to the destination as a recommended route in a predetermined color (for example, red).

  The navigation device 1 according to the present embodiment performs a normal peripheral facility search for searching for a destination from facilities near the current position, and a peripheral facility search based on predetermined search conditions when the preset button 43 is operated. It has a preset search function.

  In the peripheral facility search, the control unit 13 extracts facilities that match the designated conditions and is close to the current position, and draws the extracted result on the display unit 4. Then, the user can select any of the candidates drawn on the display unit 4 and confirm the selection to designate the destination (including a stopover).

  In order to implement the peripheral facility search, the database 14 stores information on each facility by classifying the information with a plurality of classification axes. The classification axis is, for example, the type of facility (eg, restaurant, supermarket, gas station, etc.), the purpose of use of the facility (eg, eating, playing, shopping, etc.), the permissible payment method (eg, cash, credit card, prepaid card, etc.). It may be determined whether or not there is a toilet, whether or not it is a chain store, whether or not a public wireless LAN is provided, the type of reward card that can be used, and the like. The control unit 13 acquires information about the facility from the database 14 in a state where the facilities are classified by the plurality of classification axes.

  Further, the information on the classification of the facilities can be efficiently specified by classifying the classification axes in stages and hierarchies such as large items, medium items, and small items. That is, one or more middle items belong to the large item, and one or more small items belong to each middle item. In the case where only one item belongs, it is actually equivalent to an item having no item at that level. That is, when there is only one small item belonging to a certain middle item, it may be determined that there is no small item up to the middle item.

  Examples of major items include “traffic”, “shopping”, “restaurants”, “leisure / sightseeing”, “stay / hot spring”, “living / life”, and the like. Examples of middle items belonging to “traffic” include “road”, “railroad”, “airport”, “ferry landing”, “roadside station / drive-in”, and the like. Examples of small items belonging to “road” include “interchange”, “smart IC”, “SA / PA / highway oasis”, and “intersection”. There is no sub-item belonging to "Airport" or "Ferry Terminal". The sub-items belonging to “shopping” include “convenience store”, “supermarket / department store / shopping street”, “food / liquor”, and “automobile-related”. The small items belonging to the “convenience store” include each chain store. The classification of the middle items belonging to the large item “restaurants” includes “family restaurant”, “fast food”, “ramen”, “Japanese food”, “Western food”, “Asian / Chinese / ethnic food”, and the like. The sub-items belonging to “Asian / Chinese / Ethnic cuisine” include “Chinese cuisine”, “Dim Sum”, “Korean cuisine”, “Yakiniku” and the like. The small items belonging to “fast food” include “hamburger”, “gyudon”, “other fast food”, and the like, which may be further divided into each chain store.

  When a large item is specified, all the middle items belonging to it are specified. When a certain middle item is specified, all the small items belonging to the middle item are specified. The control unit 13 performs the processing.

  When the peripheral facility search is selected on the search menu screen, the control unit 13 draws a classification information selection menu on the display unit 4. In the present embodiment, the facilities are classified into three levels, large, medium, and small. Therefore, a menu for selecting a large item is drawn first. The user touches or selects a desired item for specifying the facility to be searched from the menu list of the large items. When receiving the instruction from the user, the control unit 13 recognizes the selected large item, and reversely displays the menu area of the selected large item, draws a check mark in a check box, and so on to the user. Notify the selected / recognized item. When the selected large item has a lower middle item, the control unit 13 displays a list of middle items in a selectable manner below the display of the selected large item. When the already selected menu area is specified again by touching or the like, the control unit 13 determines that the selection is released and returns to the initial display state.

  To select a lower middle item of the selected large item, a desired item is selected from the list of middle items displayed below the selected large item by touching or the like. The selected middle item is drawn in a recognizable manner as in the case of the large item, and if there is a lower-order small item, the list is displayed below the selected middle item.

  The user touches the search button 40 displayed on the display unit 4 when the user can search the peripheral facility search with the selected item. In response to the user's instruction, the control unit 13 acquires the facility corresponding to the selected item from the database 14, and displays the facilities in order from the facility which is easy to go from the current position. The facilities that are easy to access from the current position are, for example, in the order of the shortest linear distance from the current position, in the order of the distance from the current position, in the order of the expected arrival time, in the order of the deviation from the route being guided, etc. Good. Subsequently, the user touches and selects a facility to be set as a destination from the displayed facilities. The selected facility is drawn in such a manner that the selection can be recognized by reverse display or a check mark, similarly to the selection of the item. Then, when the user touches the guidance start button displayed on the display unit 4, the position information of the selected facility is set as the search end position in the guidance function, and the recommended route is searched.

  In the navigation device 1 according to the present embodiment, the control unit 13 is configured to be able to execute a peripheral facility search based on search conditions extending over a plurality of classification axes. The “search condition over a plurality of classification axes” means that, for example, a logical operation (for example, a logical sum, a logical product, a logical negation, etc.) of the search condition by a plurality of classification axes is set as the search condition. As a specific example of a method of setting a search condition based on a plurality of classification axes, in the navigation device 1 of the present embodiment, as shown in FIG. 41 is displayed on the display unit 4. Then, when the user touches the AND search button 41, the classification information selection menu is displayed again in order to select the second item to be searched by logical AND with the selected item. The user selects the second item in the same procedure as when selecting the first item. When the search button 40 is touched in a state where the second item is selected, the control unit 13 acquires from the database 14 facilities belonging to both the first item and the second item, and They are displayed side by side in the order from the closest position.

  As a specific application example, if you select “convenience store” as the first item and select “with toilet” as the second item and search for peripheral facilities by logical product, there is a convenience store with a toilet. Stores can be searched around the current location. The control unit 13 can also perform a search by a logical sum of more items in the same procedure as described above. In addition to an AND search button 41, an OR search button for performing a search by a logical sum and a logical NOT (exclusion condition) are set in addition to the AND search button 41 to enable a search by a logical sum or a logical negation other than the logical product. A NOT search button may be displayed.

  As described above, in the peripheral facility search, the classification is hierarchically structured, and a search across a plurality of classification axes is permitted. Operation is required. For this reason, in order to perform a peripheral facility search, it is necessary to stop driving once and watch the screen carefully. In order to solve this problem, the navigation device 1 according to the present embodiment sets a search condition of the database 14 in advance in association with a standard input operation to the input receiving unit, and performs a search based on the condition set by the standard input operation. It has a preset search function that enables Since a peripheral facility search can be performed according to preset search conditions by a standard input operation, it is possible to easily perform a peripheral facility search without having to stop once and watch the screen. Hereinafter, the preset search will be described.

  In the navigation device 1 of the present embodiment, the input receiving means for setting search conditions is the preset button 43 displayed on the display unit 4, and touching the preset button 43 is a standard input operation. Although the preset button 43 is not displayed on the navigation screen normally displayed during traveling of the vehicle shown in FIG. 5, when a touch on the preset call button 33 is detected, the screen transits to the screen shown in FIG. , Two preset buttons 43 are displayed at the left end of the display unit 4. When a touch on the displayed preset button 43 is detected, a peripheral facility search is executed based on preset search conditions. More than two preset buttons 43 may be provided. In the example shown in FIG. 9, the two preset buttons 43 are displayed so as to be superimposed on a part of the own vehicle speed display section 34 and a part of the menu bar 36, but other display areas such as the current time display section 30 and the menu bar The preset buttons may be displayed in more parts of the 36 and the area where the map is displayed. When the touch on the preset call button 33 is detected, the display is made before the touch on the preset call button 33 is detected, as particularly shown as a transition from the display of FIG. 5 to the display of FIG. A part of the preset button is displayed by hiding a part of the button and displaying the area including the button, or by overlapping the button displayed before the touch on the preset call button 33 is detected. 43 may be displayed. By doing so, the preset button 43 can be more easily touched, and the preset search can be performed more easily.

  The input receiving means is not limited to this, and various forms of realization are possible. For example, the preset button 43 may be displayed on a navigation screen normally displayed while the vehicle is running. In this case, the preset search can be executed by one operation. Further, instead of the button displayed on the display unit having the touch panel, a mechanical switch such as the operation button 6 may be used as the input receiving unit. Further, in the navigation device 1 that enables voice input, a microphone may be used as input receiving means, and voice input of a predetermined command word such as “preset search execution” may be a standard input operation. In any case, it is preferable that the input receiving means be configured to be able to receive an input operation while the vehicle is traveling, and it is preferable to receive the input operation while a map including the current position is displayed. With such a configuration, a standard input operation can be performed immediately from the state where the map is displayed. In particular, if the input receiving means is configured so as not to disturb the map display, it is possible to receive the presentation of the facility corresponding to the search condition associated with the standard input operation without disturbing the map display while the vehicle is running. Can be. In the present embodiment, the preset call button 33 and the preset button 43 are configured to be able to receive an input operation during traveling.

  Further, it is preferable that the input receiving means is arranged at a fixed position where the driver can input an operation instruction. With such a configuration, an input operation can be performed without having to search for an input receiving unit. For example, even when the user is driving the vehicle, he / she can smoothly perform the standard input operation without worrying about searching for the input receiving means. In the present embodiment in which the preset button 43 displayed on the display unit having the touch panel is used as an input receiving unit, the preset button 43 is displayed at a predetermined fixed position in the display unit 4. The standard input operation is preferably an input operation performed by the driver within two times. In this embodiment, the input operation is a touch operation on the preset call button 33 and a touch operation on the preset button 43 twice.

  The search condition that is executed when the preset button 43 is touched is set in advance by the following procedure in a state where the traveling of the vehicle is stopped. First, an item is selected in the same manner as in the case of performing a peripheral facility search, and if necessary, an item is selected across a plurality of classification axes by an AND search. Then, in a state where the item shown in FIG. 8 is selected, the user touches the preset setting button 42 displayed together with the search button 40 and the AND button. When the touch on the preset setting button 42 is detected, the control unit 13 displays a selection button on the display unit 4 for accepting selection of which of the two preset buttons 43 to set the search condition. Then, the control unit 13 stores the number of the selected preset button 43 and the search condition based on the selected item in the EEPROM in association with the operation of the selection button by the user.

  When a touch on the display position of the preset button 43 is detected by the touch panel, the control unit 13 reads a search condition corresponding to the number of the preset button 43 at the touched position from the EEPROM, and stores a facility corresponding to the read search condition in a database. 14 and are displayed in order from the facility that is easy to access from the current position. The user touches and selects the facility to be set as the destination from the displayed facilities, and touches the guidance start button, so that the position information of the selected facility is displayed at the end position of the search in the guidance function (for example, the destination ). As described above, by simply touching any one of the preset buttons 43, the peripheral facility search is performed according to the search condition set in the preset button 43, so that the user can continue traveling toward the target place while You can know the facilities that you can stop by in the order of easy access.

  The navigation device 1 according to the present embodiment enables the preset search as described above. However, when the number of facilities displayed as the search result is large, the user gazes at the display unit 4 to set a destination. May require. Therefore, the navigation device 1 of the present embodiment has a facility presentation function of presenting to the user a facility extracted by the preset search without setting the facility for the purpose. When a touch on the preset button 43 is detected, it is determined in advance whether to perform a search for setting the search end position in the guide function or to present a facility by the facility presentation function in the same manner as a normal peripheral facility search. It shall be set.

  When the facility presentation function is executed, the control unit 13 performs a peripheral facility search according to a preset search condition, acquires a facility corresponding to the search condition from the database 14, and recognizes the order of facilities that are easy to go from the current position. In a possible manner, control is performed so as to present the predetermined N facilities to the user. Specifically, for example, the facility to be presented may be displayed as an icon at a position corresponding to the facility in a map including the current position. The location of the presented facility can be confirmed on the map, and the user can be provided with information for determining whether to stop by the presented facility. A facility other than the facility to be presented may be displayed on the map, but the facility to be presented is preferably displayed so as to be more prominent than the facilities other than the facility to be presented. Thus, the facility presented on the map can be found at a glance without watching the screen. For example, an arrow may be displayed on a map starting from the current location and ending at the location of the facility to be presented. Such a display allows the user to intuitively recognize the direction and distance from the current position. In addition, the icon may be displayed blinking or enlarged at the position on the map of the facility to be presented. It is further preferable that the icon of the facility to be presented is set so that it can be set as a destination used for the guidance function.

  At this time, the scale of the map is adjusted by the auto scale so that the current position and the N facilities can be displayed, and control is performed so that icons of the N facilities are drawn on the screen. The N number may be a fixed number. However, it is preferable that the number is selected for each preset button on the setting screen, and the number of the preset button and the number are stored in association with each other. In the case of this configuration, when any one of the preset buttons is touched, the control is performed such that the facility icons corresponding to the number stored in association with the touched preset button are drawn. Further, for example, the control unit 13 sets the scale of the map to the maximum scale that can simultaneously display the current position and the facility to be presented. Further, information indicating the scale is drawn on the map scale display section 32. Thereby, the user can easily recognize the distance to the facility to be presented. Presentation by the facility presentation function may be performed by a predetermined number, regardless of how far the facility to be presented is from the current position.

  In the navigation device 1 according to the present embodiment, in the facility presentation function, the control unit 13 performs control so as to perform the facility located in the traveling direction of the vehicle. The traveling direction is set in advance as, for example, a range of a predetermined angle of less than 90 degrees left and right in front of the vehicle. The “traveling direction” is not limited to the above. For example, for a range relatively close to the current position (for example, less than 1 km), a relatively wide predetermined angle range in front of the vehicle (for example, within 60 degrees left and right) is set as the traveling direction, and a range relatively far from the current position (for example, 1 km or more). As for the traveling direction, a relatively narrow angle range in front of the vehicle (for example, within 30 degrees left and right) may be used as the traveling direction.

  Then, when the facility presenting deviates from the traveling direction of the vehicle, the control unit 13 stops the presentation of the facility deviating from the traveling direction and performs control to present a new candidate in the traveling direction. By such control, for example, facilities that deviate from the traveling direction by passing or changing the traveling direction by continuing traveling are excluded from the targets of presentation, and it becomes easier to find a new candidate in the traveling direction. In order to effectively realize the change of the presentation according to the change of the traveling direction, it is preferable to periodically update the facility to be presented. Here, “periodically” may be defined as every predetermined time, every predetermined time interval, every predetermined moving distance, or the like. The predetermined may be constant or variable.

  In the navigation device 1 of the present embodiment, the facility presentation function may be executed simultaneously with the guidance function. When the facility presentation function is executed at the same time as the guidance function, the facility presented by the facility presentation function and the search end position in the guidance function may be displayed in different modes. As a result, it is possible to prevent erroneous recognition or confusion between the end position of the search by the guidance function and the facility presented. The presentation in the facility presentation function may be performed for facilities located around the recommended route searched by the guidance function. The periphery of the route may be, for example, an area in which the shortest distance to the route is within a predetermined range. Specifically, for example, when a visit to the facility is made, it is preferable to display the facilities in order from the facility with the smallest deviation from the recommended route. With such a configuration, it is possible to know the facilities that can be dropped in while traveling along the route being guided, in the order of easy access.

Further, the following configuration may be provided.
The search condition assigned to the preset button 43 may be set, for example, for each time zone. For example, the time is divided into three time zones such as morning, daytime, and night, search conditions are set for each time zone, and the current time acquired from the GPS receiver 11 when the preset button 43 is operated is included. It is good to search according to the search condition of the time zone to be performed. In this way, different needs can be answered with a small number of buttons depending on the time zone.

  Further, at least one of the preset buttons 43 may be assigned to a function other than the preset search function. For example, a television receiving function is further provided, and a received video of a television broadcast is displayed on a map in PinP (Picture in Picture). For example, a function to preset a favorite broadcast station (Fuji TV or NHK) to any of the preset buttons 43 is provided. For example, when a morning continuous TV novel (program name: Amachan) starts, it is switched with a single button. It may be. For example, at 7:00 in the morning, the user wants to watch Fuji TV's alarm TV (program name) as much as possible. If there are too many, the merit will be diminished, so a few) If you preset, there is a great merit that you can watch the current program to the last minute. Also, in the morning, the two stations may be preset for each time zone, such as two stations in the evening and another two stations in the evening, and the channel assigned to the preset button 43 may be switched according to the time zone. In this way, an operation that meets the needs can be performed in a timely and easy manner. In particular, since it is not possible for the driver to change the program while watching the video on the program guide, it is more pleasing to the user that the driver can easily switch with the preset button 43 which is a small number of buttons displayed on the map.
