  Due to the development of information technology, information processing apparatuses mounted on vehicles and performing various information processing have been steadily becoming more sophisticated. One means for reducing the burden of user operations that increase as the information processing apparatus becomes more sophisticated is a GUI (Graphical User Interface) using a touch panel or the like. Similarly, when providing the above-described peripheral facility search function to the user, the GUI on the touch panel is useful for searching and displaying the peripheral facilities.

  Here, it should be noted that when searching for peripheral facilities and displaying them, the operability of the user is still important. By using the GUI, it is possible to allow the user to make various operational selections, but on the other hand, if too much GUI is used, the display becomes complicated and the operability can be avoided. Absent. In particular, in an information processing apparatus that performs vehicle navigation, a navigation map is indispensable. However, when a GUI for a search for nearby facilities and operations related thereto is performed based on the navigation map, the user can The navigation of the vehicle and the search for surrounding facilities are confused, and a comfortable operating environment for the device cannot be provided.

  The present invention has been made in view of such problems, and in an information processing apparatus that performs vehicle navigation, in providing the user with a search facility for surrounding facilities, avoids confusion in the operation of the user, The purpose is to improve the performance.

In order to solve the above-described problems, the present invention separates a map for vehicle navigation and a map for searching for and displaying surrounding facilities, and performs user operations related to searching for surrounding facilities. The button on the touch panel by the GUI for accepting is displayed together with a map for displaying the surrounding facilities. By doing in this way, since the user will recognize different display maps at the time of normal vehicle navigation and at the time of searching surrounding facilities, it becomes possible to improve the operability of the information processing apparatus.

  Specifically, the present invention is an information processing apparatus mounted on a vehicle and capable of processing navigation information of the vehicle, and includes a touch panel that can display an image and accept a touch operation by a vehicle occupant, and the vehicle itself. Based on the vehicle position information, a navigation unit for displaying the vehicle position on a navigation map set on the touch panel, and a peripheral facility existing around a predetermined reference point appearing on the touch panel are searched for on the touch panel. A peripheral facility search unit that displays the searched peripheral facility on a map set as a peripheral display map different from the navigation map, and a search for peripheral facilities by the peripheral facility search unit, In a predetermined display area defined on the touch panel, together with the peripheral display map and the searched peripheral facility, the peripheral application is displayed. And a least one displaying the search result display unit operating buttons for accepting an operation related to the surrounding facilities performed by the user based on the search result by the search unit.

  The information processing apparatus is an apparatus that is mounted on a vehicle and provides various information to the user including vehicle navigation information. Here, the user gives an instruction to the information processing apparatus through a GUI such as a button shown on the touch panel, but it is not necessarily limited to the touch panel alone, and other interfaces, for example, hard switches provided in the apparatus Or via a physical interface such as a dial.

  Here, in the information processing apparatus, the navigation of the vehicle is performed by the navigation unit. At this time, a navigation map is displayed on the touch panel to indicate the vehicle position to the user. The user can preferably perform operations related to navigation such as changing the display state of the map by touching the navigation map. Further, the information processing apparatus searches and displays surrounding facilities as one of high-functional information provisions to the user. This peripheral facility search is performed by searching for a specific facility existing around a predetermined reference point (for example, the vehicle position) serving as a reference on the map displayed on the touch panel, preferably a facility that the user wants to know about the location. To do. The surrounding facilities will eventually be displayed on the navigation map and used to provide useful information to the user, such as navigating the vehicle, etc. The user's operation related to the search for surrounding facilities such as display is not necessarily performed based on the navigation map. On the contrary, there is a possibility that the user's operation may be confused.

  Therefore, in the information processing apparatus, when the peripheral facility search unit searches for the peripheral facility, the searched peripheral facility is displayed on the peripheral display map set as a map different from the navigation map on the touch panel, and the search is performed. Accordingly, the result display unit displays operation buttons for accepting operations related to surrounding facilities in one predetermined display area. As a result, the user can perform operations related to surrounding facilities on a map different from the map on which navigation is performed, so that the user can be prevented from being confused on the operation of the device. This leads to improved operability of the apparatus.

  Here, in the information processing apparatus, the map for peripheral display is set so that a change in the position of the vehicle is not reflected in the map for peripheral display even when the navigation unit performs navigation of the vehicle. You may comprise so that it may become independent from the map for navigation. Even when the vehicle is being navigated, the map for the peripheral display is displayed in a functionally independent manner from the map for navigation display, so the user navigates the map shown when searching for nearby facilities. It is not confused with the work map, and operations related to surrounding facilities can be performed with a sense of security.

  Here, in the information processing apparatus described above, the search result display unit displays the peripheral facility on the peripheral display map regardless of the scale state of the navigation map displayed by the navigation unit. The scale of the map for peripheral display may be adjusted based on the distance between the searched peripheral facility and the predetermined reference point. Again, because the map for surrounding display is set as a map different from the map for navigation on the touch panel, it is not necessary to restrict the display to the navigation conditions of the vehicle, and conversely for effective display of surrounding facilities. It is possible to adjust the display state appropriately. The present applicant pays attention to this point and decides to set a map scale so that the user can easily grasp the peripheral facilities based on the distance between the peripheral facilities and the vehicle searched as described above. As a result, for example, because the scale of the navigation map is in an expanded state, the searched surrounding facilities cannot be displayed on the map, or the searched surrounding facilities are too dense. A state in which the user cannot grasp can be avoided.

  Preferably, when the search result display unit displays the peripheral display map to the user, at least the nearest peripheral facility closest to the predetermined reference point among the searched peripheral facilities is the peripheral display map. The scale of the map for peripheral display is adjusted so that it appears inside. By doing so, the latest peripheral facilities are always displayed on the peripheral display map, so that it is possible to respond to the user's search request for the peripheral facilities.

  Here, in the information processing apparatus described above, the search result display unit serves as the operation button to the user according to a display order based on at least a distance between the searched peripheral facility and the predetermined reference point. A distance reference display button for displaying the searched peripheral facilities may be displayed on the touch panel together with the peripheral display map.

  When the user searches for a nearby facility, there may be a request to know the distance between the vehicle position and the searched nearby facility. Therefore, by displaying the distance reference display button in the predetermined display area on the touch panel together with the peripheral display map, the user's operation can be met without confusion. When the distance reference display button on the touch panel is pressed by the user, peripheral facilities searched in a list state are provided on the touch panel.

  Here, the user may want to extract a peripheral facility that satisfies a certain condition according to his / her wish from the peripheral facilities displayed in the list state. One of the cases is when the navigation of the vehicle is performed by the navigation unit. In other words, since the user would normally want to avoid an unfavorable influence such as greatly deviating from the navigation route at the time of navigation, the navigation route should be increased in that way from the surrounding facilities initially searched. There is a great demand for extracting a peripheral facility that satisfies the predetermined condition of not falling off. Therefore, when the peripheral facility is displayed as a list by pressing the distance reference display button by the user, it is determined that the peripheral facility along the navigation route indicated by the navigation unit is displayed together with the peripheral facility in the list display state. A route along facility extraction button for extracting a facility along the route that satisfies the predetermined condition from the searched surrounding facilities may be displayed.

As for the facility extraction button along the route, when the vehicle is being navigated by the navigation unit, the facility extraction button along the route can accept an input from the user in an emphasized state on the touch panel. When the vehicle is not being navigated by the navigation unit, the facility extraction button along the route is in a non-emphasized state and cannot accept input from the user on the touch panel. It may be displayed. The facility extraction button along the route is a button that does not function unless the navigation of the vehicle is performed by the navigation unit, but even if the navigation is not performed, the button itself is not stopped and is not highlighted. By displaying in a state where the appeal power is weaker than the user's visual perception, the user can be informed of the presence of the button itself. As a result, if the user wants to use the facility extraction button along the route, the user can intuitively feel that the vehicle should be navigated by the navigation unit, which improves the operability of the information processing apparatus. To contribute.

  Here, in the information processing apparatus up to the above, when the peripheral facility is searched for by the peripheral search unit, the search result display unit sets the navigation map on the touch panel in a state of being covered with the predetermined display area. Also good. By hiding the navigation map, the possibility of user confusion is extremely low.

  Further, the present invention can also be grasped from the side of a control device that has a touch panel that can display an image and accept a touch operation by a vehicle occupant and that process navigation information of the vehicle. That is, the control device includes a navigation unit that displays the vehicle position on a navigation map set on the touch panel based on the vehicle position information of the vehicle, and a predetermined reference point that appears on the touch panel. A peripheral facility search unit that searches for existing peripheral facilities and displays the searched peripheral facilities on a map that is set as a peripheral display map different from the navigation map on the touch panel, and the peripheral facility search unit When the peripheral facility search is performed, the user is based on the search result by the peripheral facility search unit together with the peripheral display map and the searched peripheral facility in one predetermined display area defined on the touch panel. A search result display unit for displaying at least one operation button for receiving an operation related to the surrounding facility performed by Configured so that.

  Further, the technical features disclosed in the information processing apparatus described above can be similarly applied to the control apparatus.

  In an information processing apparatus that performs vehicle navigation, it is possible to avoid user confusion and improve operability when providing a user with a search function for peripheral facilities.

As shown in FIG. 9, the video processing function unit 57 includes “radio”, “CD”, “one segment”, “iPod”, “external input”, “OFF”, and a source selection area in the AV area. Display the “AV” button. When any source button is touched, that source is selected. In the example of FIG. 9, “radio” is selected, and operation buttons and information related to the selected source, such as a reception frequency, an AM / FM switching button, and a channel selection button, are displayed in the source operation area. The state is illustrated. Therefore, at this time, the audio processing function unit 56 outputs the audio signal of AM broadcast received by the broadcast wave receiving unit 7 from the speaker via the amplifier 12. On the other hand, in addition to the map drawn on the navigation area based on the map data read by the map data processing function unit 54, the video processing function unit 57 “menu”, “destination”, “periphery”, “home” , “Navi”, “map enlargement”, and “map reduction” buttons are displayed. In the multi-screen (D102), there are two AV areas and a navigation area, so the AV area is narrower than that of the AV full-screen (D104). Therefore, only the basic operation buttons and information related to the source are displayed in the source operation area of the multi-screen (D102).

  When the operation processing function unit 51 detects that the “AV” button is pressed in this state, the video processing function unit 57 transitions to the screen display state of the AV full screen (D104). The case where other buttons are pressed will be described in detail after explanation of the navigation full screen (D103) and the AV full screen (D104).

  (D103) Next, the entire navigation screen (D103) will be described. When the operation processing function unit 51 detects that the “navi” button displayed on the multi-screen (D102) has been pressed, the video processing function unit 57 gradually hides the AV area and displays the navigation area on the entire screen. To do. FIG. 10 is a diagram of a full navigation screen. As shown in FIG. 10, the video processing function unit 57 deletes the AV area and displays the navigation area on the touch panel 21 in full screen.

  As shown in FIG. 10, a map and operation buttons such as “Menu” and “Destination” are displayed in the navigation area, as in the multi-screen (D102). Here, the video processing function unit 57 displays the screen so that the icon of the vehicle position displayed on the entire navigation screen is positioned at the center of the navigation area. For this reason, when the display screen of the touch panel 21 transitions from the multi-screen (D102) to the full navigation screen (D103), the icon of the vehicle position and the display of the map are slightly scrolled within the screen. On the other hand, the video processing function unit 57 displays the screen so that operation buttons such as “menu” and “destination” are at the same position on the display screen of the touch panel 21. For this reason, even if the display screen of the touch panel 21 transitions from the multi-screen (D102) to the navigation full screen (D103), the navigation operation buttons do not scroll on the screen of the touch panel 21 and continue to be displayed at the same position. However, only the “navigation” button is switched to the “AV + navigation” button. When the “AV + Navi” button is pressed, the video processing function unit 57 switches the display from the full navigation screen (D103) to the multi-screen (D102).

  (D104) Next, the AV full screen (D104) will be described. When the operation processing function unit 51 detects that the “AV” button displayed on the multi-screen (D102) is pressed, the video processing function unit 57 gradually hides the navigation area and displays the AV area on the entire screen. To do. FIG. 11 is a diagram of an AV full screen. As shown in FIG. 11, the video processing function unit 57 erases the navigation area and displays the AV area on the touch panel 21 in full screen.

As shown in FIG. 11, the AV area has “radio”, “CD”, “one-segment”, “iPod”, “external input”, and “OFF” buttons as in the multi-screen (D102). Is displayed. Also, in the AV area, the source operation area is enlarged, and the names of broadcast stations, preset channel selection buttons, channel setting buttons, and sound setting buttons that have not been displayed on the multi-screen (D102) are displayed. Further, “CDIN” indicating that a CD is inserted in the CD drive 16 is displayed. Here, in the AV area, operation buttons such as “radio” displayed on the multi-screen (D102) are displayed at the same position. However, only the “navigation” button is switched to the “AV + navigation” button. Hereinafter, an area displayed on both the multi-screen and the AV full screen is referred to as an “AV normal area”, and an area displayed only on the AV full screen is referred to as an “AV extension area”. When the “AV + Navi” button is pressed, the video processing function unit 57 switches the display from the AV full screen (D104) to the multi-screen (D102). In the AV full screen (D104), since there is no navigation area, the AV area is wider than that in the multi-screen (D102). Therefore, all operation buttons and information related to the source are displayed in the source operation area of the AV full screen (D104). As described above, the source operation button and information display area displayed only in the case of the AV full screen (D104) are the “AV extension area”, and constitute a part of the source operation area. On the other hand, the source operation button and information display area displayed on both the multi-screen (D102) and the AV full-screen (D104) are “AV normal area”, and a part of the source operation area and the source selection area And make up.

  The screen transition (FIG. 6) of the main screen of the navigation device 1 is as described above. Hereinafter, how the navigation area and the AV area move on the screen when the screen changes from the multi-screen (D102) to the navigation full screen (D103) or the AV full screen (D104) will be described in detail. FIG. 12 is a diagram showing how the AV area disappears when transitioning from the multi-screen (D102) to the full navigation screen (D103). FIG. 13 is a diagram showing how the navigation area disappears when transitioning from the multi-screen (D103) to the AV full-screen (D104). The video processing function unit 57 displays the screen so that the navigation area and the AV area are scrolled when the display is switched from the multi-screen to the navigation or the AV full screen. That is, when the video processing function unit 57 switches the display from the multi-screen to the entire navigation screen, the AV area gradually exits to the left side, in other words, the display area of the AV area gradually decreases. And the screen is displayed so that the display area of the navigation area is gradually increased. Further, when switching the display from the multi-screen to the AV full screen, the video processing function unit 57 displays the screen so that the AV area gradually enters the right side. Thereby, the user can feel as if the AV screen is inserted and removed on the navigation screen. Therefore, if you want to see the navigation screen, you can easily understand visually that the transition to the full navigation screen (D103) is made by pressing the “navigation” button displayed on the right side of the multi-screen (D102). If the user wants to see the AV screen, the user can easily understand that the AV screen is inserted and removed by pressing the “AV” button displayed on the left side of the multi-screen (D102). FIG. 14 is a conceptual diagram showing a state of screen transition of the main screen. As shown in FIG. 14, the user has a left side (corresponding to an AV screen in this embodiment) on a right side (corresponding to a navigation screen in the present embodiment) that can be seen through a display window. ) Can be operated on the main screen of the navigation device 1 with an image that is inserted and removed from the left side. Therefore, it is easy to understand where you are now and you can operate with confidence.

  (D201) Next, a screen related to navigation of the navigation device 1 will be described. First, the menu screen (D201) will be described. When the operation processing function unit 51 detects that the “menu” button displayed in the navigation area of the multi-screen (D102) or the entire navigation screen (D103) is pressed, the video processing function unit 57 displays the menu screen (D201). ) Is displayed on the touch panel 21. FIG. 15 is a diagram of the menu screen (D201). As shown in FIG. 15, the video processing function unit 57 displays a menu pop-up so as to start up from the “menu” button in the navigation area. Here, the video processing function unit 57 displays an animation so that the menu pop-up gradually rises from the “menu” button, and further allows the multi-screen (D102) to be seen below the pop-up. Note that a pop-up is an area displayed so as to rise from the button when a button displayed on the screen is pressed, for example, an area where menu items and the like are displayed. FIG. 16 is a diagram showing an animation when transitioning from the multi-screen (D102) to the menu screen (D201). When the “Menu” button on the multi-screen (D102) is pressed, a menu pop-up is displayed so as to start up from the “Menu” button. Therefore, the user can easily understand visually that the menu screen has been shifted from the multi-screen, and the previous display screen is located below the pop-up display screen. Can be operated with peace of mind. The menu screen (D201) displays user setting buttons such as icons and facility display, and favorite point editing buttons. The point information registered by the user is stored in the RAM in the control unit 20 by the user data processing function unit 55.

  (D202) Next, the destination setting screen (D202) will be described. When the operation processing function unit 51 detects that the “destination” button displayed in the navigation area of the multi-screen (D102) or the entire navigation screen (D103) is pressed, the video processing function unit 57 sets the destination. The screen (D202) is displayed on the touch panel 21. That is, as shown in FIG. 17, the video processing function unit 57 displays a pop-up in which a destination setting button is arranged so as to stand up from the “destination” button in the navigation area. When the operation processing function unit 51 detects that any of the destination setting buttons has been pressed, the video processing function unit 57 displays a screen corresponding thereto. For example, the video processing function unit 57 displays a screen for inputting characters when the “Search by 50 sounds” button is pressed, and displays a screen for selecting a prefecture or the like when the “Search by address” button is pressed. If the “Search by mobile phone link” button is pressed, a screen prompting the user to bring the mobile phone closer to the infrared receiver / light emitting unit 25 is displayed. If the “Search by history” button is pressed, the user has searched in the past. Display destinations with The communication data provided from the mobile phone by the infrared receiving / emitting unit 25 includes position information such as the latitude and longitude of the destination, or an address and a telephone number. When the destination is set by the screen displayed when the “50-sound search”, “search by address”, “search by mobile link”, or “search by history” button is pressed, the route guidance function unit 53 performs positioning. The function unit 52 searches for the shortest route to the vehicle position and destination measured by the function unit 52, and starts route guidance. Note that conventional techniques can be applied to the route guide, and a detailed description thereof is omitted.

  (D203) Next, the peripheral facility search screen (D203) will be described. When the operation processing function unit 51 detects that the “periphery” button displayed in the navigation area of the multi-screen (D102) or the entire navigation screen (D103) is pressed, the video processing function unit 57 (D203) is displayed on the touch panel 21. That is, as shown in FIG. 18, the video processing function unit 57 displays an animation of a popup in which buttons for searching for nearby facilities are arranged so as to rise from the “periphery” button in the navigation area. Then, as in D203 described above, if any button is pressed, a corresponding screen is displayed. That is, when the “periphery” button is pressed, the video processing function unit 57 displays a button that allows the user to select the category of the facility to be searched, and when the search target category is designated, The nearby facilities corresponding to the specified category, such as gas stations and convenience stores in the area, are displayed in order of proximity to the vehicle. Note that specific peripheral facility search processing will be described later.

  (D204) Next, the intersection enlargement screen (D204) will be described. The destination is set on the destination setting screen (D202) or the peripheral search screen (D203) described above, or the “Home” button displayed on the multi-screen (D102) or the entire navigation screen (D103) is displayed. When the destination is set by being pushed, route guidance by the route guidance function unit 53 is started. The route guidance function unit 53 performs route guidance based on the vehicle position measured by the positioning function unit 52 and the map data read from the card memory by the map data processing function unit 54. The route guidance function unit 53 displays an enlarged intersection screen (D204) and passes voice data for route guidance to the voice processing function unit 56 when the vehicle approaches an intersection that makes a right turn or a left turn. FIG. 19 is a diagram showing an intersection enlarged screen (D204). As shown in FIG. 19, an enlarged view of an intersection is displayed in the navigation area, and the route that the vehicle should travel is indicated by an arrow. At this time, audio / visual operation buttons are displayed in the AV area.

Next, an AV screen display mode of the navigation device 1 will be described. As shown in FIG. 8, the AV screen of the navigation device 1 is prepared with six screens of a radio mode, a CD mode, a one-segment mode, an iPod mode, an external input mode, and an off mode. When one of the source selection buttons or the “OFF” button prepared on the left side of the AV area is pressed, the video processing function unit 57 displays an AV operation screen of a mode corresponding to the button. For example, when the “radio” button is pressed, the video processing function unit 57 displays a radio frequency and a channel selection button as shown in FIG. The same applies to the CD and iPod buttons. In addition, when the “One Seg” button or the “External Input” button is pressed, the video processing function unit 57 displays a channel selection button or the like in the AV area and displays the navigation area from the video from the broadcast wave receiving unit 7. And switching to the video of the external audio / video input unit 8. However, when the brake detection unit 4 detects the release of the parking brake signal, the video processing function unit 57 stops the video display from the broadcast wave receiving unit 7 and the external audio / video input unit 8.

  The operation of the navigation device 1 has been described above. The navigation apparatus 1 according to the present embodiment divides the screen display into two areas of AV and navigation in order to improve the operability of both AV and navigation. The operation buttons for performing AV and navigation operations are displayed at the same position on the screen, thereby facilitating the screen operation using the touch panel 21. In the above-described embodiment, the description has been given for in-vehicle use. However, the present invention can be applied to any apparatus that can be used for in-vehicle use. For example, the present invention can be applied to an electronic device having a portable navigation function.

<About peripheral facility search>
As described above, the navigation apparatus 1 can search for nearby facilities. The details will be described below. This search for nearby facilities is performed not only when the navigation route is being guided by the route guidance function unit 53 but also by the functions of the map data processing function unit 54 and the video processing function unit 57 on the touch panel 21. It can also be executed when map information such as the current vehicle position of the vehicle is displayed. That is, based on the information displayed on the touch panel 21, the peripheral facility search process is performed in response to a request that the user wants to acquire information on a facility around a predetermined reference point such as the vehicle position. . Accordingly, the navigation unit according to the present invention includes the route guidance function unit 53 as a part thereof, and further includes a function unit that indicates the current position of the vehicle on the navigation map without guiding the navigation route that the vehicle should travel. Is included.

  Here, FIG. 20 shows a detailed configuration of the peripheral facility processing function unit 58 for searching for peripheral facilities. FIG. 20 is also a functional block diagram realized by execution of a computer program as in FIG. Specifically, the peripheral facility processing function unit 58 mainly includes a search request reception unit 58a, a peripheral facility search unit 58b, a scale determination unit 58c, a map display unit 58d, a list display reception unit 58e, a list display unit 58f, along a route. A facility extraction button display portion 58g, a route along facility extraction reception portion 58h, and a route along facility display portion 58i are included.

  The search request receiving unit 58a receives a search request for peripheral facilities from the user, and the peripheral facility search unit 58b searches for peripheral facilities according to the request. In the navigation apparatus 1 according to the present embodiment, as a reference point for searching for nearby facilities, the vehicle position of the vehicle shown on the touch panel 21 or the center of the map displayed on the touch panel by the user When the vehicle is not located in the position, the map center position is adopted. Therefore, the peripheral facility search unit 58b searches for facilities that are within a certain distance from the reference point as peripheral facilities. Further, the scale determining unit 58c determines the scale of the map when displaying the searched peripheral facility on the display map, and the map display unit 58d displays the peripheral facility on the map. At this time, in addition to the peripheral facilities, operation buttons for accepting operations related to the peripheral facilities are also displayed. Details will be described later.

The list display receiving unit 58e receives a list display request from the user via the button of the list display unit as the operation button, and the list display unit 58f performs list display according to the request. The route along facility extraction button display unit 58g is an operation for extracting a specific peripheral facility based on the positional relationship between the navigation route and the peripheral facility when the route guidance function unit 53 performs the route guidance. It adjusts how the button is displayed on the touch panel 21. Then, the facility extraction receiving unit 58h along the route receives a user facility extraction request obtained via the route along facility extraction button displayed by the route along facility extraction button display unit 58g. After that, the route facility display unit 58i displays the route facility extracted according to the user's request on the map.

  Here, the processing flow of the peripheral facility in the navigation device 1 by the peripheral facility processing function unit 58 having such a function unit will be described with reference to FIGS. 21 and 22 are flowcharts of the peripheral facility search process and the option process executed by the peripheral facility processing function unit 58. The former process is a process for searching for facilities existing around a predetermined reference point and displaying the peripheral facilities on a map for peripheral display set on the touch panel 21 for displaying the peripheral facilities. The latter process is a process for extracting and displaying a facility that satisfies a predetermined condition along the navigation route from the peripheral facilities searched in the former process.

  First, the peripheral facility search process will be described. In S101, a search request for peripheral facilities from the user is accepted. The processing is executed by the search request receiving unit 58a. Specifically, as shown in FIG. 18, the search request receiving unit indicates that the user has pressed the “peripheral” button displayed on the touch panel 21. By detecting 58a, a user's search request is accepted. Thereafter, in S102, the genre of the facility searched for as a peripheral facility is received. Specifically, as shown in FIG. 18, the user is prompted to select from “gas station”, “convenience store”, “parking lot”, and “family restaurant”, and the user's selection is set as facility genre information as S101. The search request receiving unit 58a receives the same as in the above. Thus, the information regarding the search request received in S101 and S102 is handed over to the surrounding facility search unit 58b, and the processes after S103 are performed. In addition, although the said four were mentioned as an example as a facility genre, you may accept selection of genres other than these naturally. Moreover, you may make it search by the subsequent process for all the surrounding facilities which do not ask | require a genre, without making a user select a genre.

  In S103, it is determined whether the display on the touch panel 21 is displaying the current location of the vehicle. When the current position display of the vehicle is performed in the navigation device 1, the vehicle marker is set to be positioned at the center of the navigation map. In other words, the navigation map displayed on the touch panel 21 in FIG. 9 (see FIG. 10, etc.), it is determined whether or not a marker indicating the vehicle is located. If the determination is affirmative, the process proceeds to S104. If the determination is negative, the process proceeds to S105. In S104, the current position of the vehicle, that is, the own vehicle position is set as a reference point for searching for surrounding facilities. On the other hand, in S105, the center position of the navigation map is set as a reference point for search. The reason why the center position of the navigation map is set as the reference point in this way is that the user may want to search for a nearby facility in a specific place regardless of the vehicle position. In this case, the user can scroll and change the display on the navigation map to display the specific place, and accept a search request for surrounding facilities at that time, so that it is possible to accurately respond to the user's request. When the process of S104 or S105 ends, the process proceeds to S106.

In S106, based on the reference point set in S104 or S105, the surrounding facilities are searched as surrounding facilities. Specifically, the location information (latitude and longitude information) of the facility that satisfies the genre information received in S102 and stored together with the map data in the memory card inserted in the card memory interface 17, Up to 200 facilities with short distances between the two points calculated from the latitude and longitude information of the reference point (hereinafter referred to as “facility distance”), from an area within a radius of 10 km centering on the reference point Search for. As described above, the processing related to the peripheral facility search in S104 to S106 is performed by the peripheral facility search unit 58.
executed by b.

  Next, after the process of S106, the process of S107 is performed. In S107, the scale of the map for peripheral display, which is a map set separately from the navigation map for the vehicle, is determined on the touch panel 21 in order to display the result of the peripheral facility. Here, an example of a map for peripheral display is shown in FIGS. 23A and 23B. Although these maps seem to be similar to the navigation map at first glance, they are separated from the navigation map in terms of map display control. Therefore, even if the position of the vehicle changes while the peripheral display map is displayed, the display change of the vehicle position is not performed following the change. In addition, the scale of the map for peripheral display is adjusted to a scale suitable for displaying the peripheral facilities and a scale suitable for performing operations related to the peripheral facilities described later, and is not restricted by the scale of the navigation map. . The determination of the scale is executed by the scale determination unit 58c, and specifically, a suitable scale is determined based on the distance between the reference point and the nearest neighboring facility. For example, as shown in FIG. 23A, when a nearby facility is located in a range relatively close to the position of the vehicle that is the reference point, the scale of the map for peripheral display is set to “400 m” as an example. As shown in FIG. 23B, when the neighboring facility is not located within a relatively close range from the reference point, the map scale shown in FIG. 23B is set larger than the map scale shown in FIG. It is adjusted so that one recent neighboring facility is displayed on the map. Therefore, the scale of the map shown in FIG. 23B is “1 km”. As described above, in S107, an appropriate scale of the map for peripheral display is determined based on the facility distance regarding the searched peripheral facility. When the process of S107 ends, the process proceeds to S108.

  In S108, the peripheral facilities are displayed, and the processing is performed by the map display unit. As described above, the peripheral facilities are displayed on the peripheral display map. For example, as shown in FIG. 23A, peripheral facilities from A to E are displayed on the map for peripheral display. Furthermore, it can be seen that operation buttons for accepting operations from the user regarding the searched peripheral facilities are displayed in places other than the peripheral display map on the touch panel. In FIG. 23A, two operation buttons of “close order” and “go here” are displayed. The description of these operation buttons will be described later. Further, as shown in FIG. 23A and the like, the display area on the touch panel is completely filled by displaying the operation buttons together with the peripheral display map. That is, on the touch panel 21, the navigation map is covered with the peripheral display map.

  As described above, when the peripheral facility is displayed, the peripheral display map and the operation buttons related thereto are displayed together, thereby making it easy for the user to perform operations related to the peripheral facility. In particular, since the map for surrounding display is separated from the map for navigation, the user can perform operations related to the surrounding facilities according to the display of the map without being affected by the navigation state of the vehicle. Remarkable.

Next, the option process shown in FIG. 22 will be described. This process is executed when the “close order” button, which is an operation button, is pressed when a map for peripheral display such as FIG. 23A is displayed on the screen of the touch panel 21. In S201, the list display accepting unit 58e accepts a request from the user for displaying a list of surrounding facilities. Specifically, when the “close order” button shown in FIG. 23A is pressed by the user, the request is processed. Here, the two operation buttons will be described. The operation button of “close order” is a button for displaying a list of peripheral facilities searched in the process of S106 in order from the reference point. An example of a screen displaying a list of searched peripheral facilities is shown in FIGS. 24A and 24B. As shown in these, details (facility name, direction from the reference point, distance from the reference point) of the peripheral facilities from A to E (peripheral facilities whose genre is bank in this embodiment) are displayed in a list. Since this list display screen is displayed in a pop-up manner from the “close order” button, the user can easily visually understand what operation he / she is currently performing. In addition, the “go here” button allows the user to select a peripheral facility displayed on the map for peripheral display by touching the button, and by pressing the “go here” button, It is set as a destination for navigation of the vehicle in the navigation device 1. After that, it is left to the processing by the route guidance function unit 53, and the display on the touch panel 21 shifts from the peripheral display map to the navigation map.

  Returning to the explanation of the option processing again. When the processing of S201 ends, in S202, it is determined whether or not the navigation device 1 is guiding the navigation route of the vehicle by the route guidance function unit 53. That is, it is determined whether or not the route on which the vehicle should travel is indicated on the navigation map. If a positive determination is made here, the process proceeds to S203, and if a negative determination is made, the process proceeds to S204. In S203, the “extract facility along route” button that is an operation button for extracting the peripheral facilities along the route from the peripheral facilities searched by the previous peripheral search process when the navigation route is set. Is set to be highlighted, and in S204, the “extract facility along route” button is set to be non-highlighted. When the process of S203 or S204 ends, the process proceeds to S205.

  In S205, as shown in FIG. 24A and FIG. 24B described above, the peripheral facilities are displayed in a list in ascending order of distance from the reference point. At this time, when the process of S205 is performed after the process of S203, the “extract facility along route” button is displayed in a highlighted state (emphasized state) as shown in FIG. 24A. At this time, the user can extract facilities along the route by pressing this button. Details of this extraction process will be described later. When the process of S205 is performed after the process of S204, the “extract facility along route” button is displayed in black (non-emphasized state) as shown in FIG. 24B. At this time, even if the user presses this button, the facility along the route cannot be extracted. Of the processes of S202 to S205, the list display portion 58f executes the list display portion, and the “route along facility extraction” button display is executed by the route along facility extraction button display portion 58g. When the processing of S205 ends, the process proceeds to S206.

  In S206, it is determined whether or not there is a user's request to extract facilities along the route. Specifically, it is determined whether or not the highlighted route extraction facility extraction button shown in FIG. 24A is pressed by the user, and the processing is executed by the route alignment facility extraction receiving unit 58h. If an affirmative determination is made here, the process proceeds to S207, and if a negative determination is made, the option process is terminated.

In S207, a process for extracting a facility along the navigation route set by the route guidance function unit 53 from the peripheral facilities searched in the previous peripheral facility search process is performed. The processing will be described with reference to the model shown in FIG. In FIG. 25, the set navigation route R1 is displayed. Here, the vehicle position is indicated by a triangle on the route R1. Here, the conditions for the searched peripheral facility to be recognized as a peripheral facility existing along the route are determined with a width of 50 m on each side from the route of the portion extending in the traveling direction from the own vehicle position. It belongs to one of the regions (regions indicated by L50 in the figure) defined by a circular arc having a radius of 50 m in the direction opposite to the traveling direction (reverse direction) from the vehicle position. . However, even if the facility belongs to L50, there is a peripheral facility in the portion where the route that the vehicle has already passed and the region L50 interfere with each other as in the region indicated by R2 in FIG. Even if it is, it shall not be recognized as a peripheral facility along the route. Note that the criteria for recognizing the facilities along the route are merely examples, and facilities along the route may be extracted according to criteria other than the above. When the process of S207 is completed, the process proceeds to S208, and the extracted facility along the route is displayed on the peripheral display map. For example, when the facilities along the route are extracted in the state where five peripheral facilities A to E are shown in the peripheral display map as shown in FIG. 23A, only the peripheral facilities B and C are extracted. As a result, only the peripheral facilities B and C are displayed on the peripheral display map. The processing in S207 and S208 is executed by the facility display unit 58i along the route.

  In this way, the facility along the route is extracted via the list display screen with the peripheral display map as a base point, so that the user's operation is easy. Further, since the peripheral facilities along the extracted route are displayed on the map for peripheral display, the user is not confused with the map for navigation, and the operations related to the peripheral facilities can be facilitated. Furthermore, as shown in FIGS. 24A and 24B, the “extract facility along route” button is displayed in either an emphasized or non-emphasized state, so that the user can be directed regardless of whether route guidance function unit 53 provides route guidance or not. Can tell the presence of the button.
