  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, in the case of providing the user with the search function for the peripheral facilities described above in relation to the vehicle navigation information, the GUI on the touch panel is useful for searching for and displaying the peripheral facilities.

  On the other hand, in many cases, a navigation apparatus can provide not only vehicle navigation information but also information by radio broadcasting and television broadcasting (hereinafter referred to as “broadcast information”) to a user. Is progressing. This is a more prominent trend as the navigation device becomes more sophisticated. However, the vehicle itself equipped with the navigation device is not always used by the same user, and the owner may change. In such a case, as long as it is a navigation device, it may be necessary to provide navigation information, but depending on the user, not all broadcast information is necessarily required. Further, depending on the user, the display specifications of navigation information using a required GUI or the like are not necessarily the same.

  The present invention has been made in view of such problems, and an object thereof is to provide information according to a user's request as much as possible in an information processing apparatus that performs vehicle navigation.

  In order to solve the above problems, in the present invention, the information processing apparatus is configured so that an information providing mode for providing broadcast information received together with navigation information via a receiving antenna to a user can be switched. By doing in this way, since an information provision mode is switched according to the kind of broadcast information which a user requires, provision of suitable broadcast information with respect to a user is attained.

  Note that the type of broadcast information provided differs between the one information provision mode and the other information provision mode, but the navigation information may be the same or different. In addition, the number of types of broadcast information provided in both information providing modes may be increased or decreased before and after switching, but the important point as the information processing apparatus according to the present invention is that both modes are connected to the information processing apparatus. Although there is no change in the hardware form of the receiving antenna, the type of broadcast information actually provided to the user is different. That is, it is important that the same information processing apparatus as hardware changes so as to provide different broadcast information according to a user's request by the mode switching unit.

  Here, in the information processing device, when the type of the broadcast information is changed by the mode switching unit, the display related to the navigation information on the display device according to the other information provision mode after the change. It is preferable to further include a display specification updating unit for updating the specification. From the viewpoint of providing information to the user, it is preferable that navigation information is appropriately matched to the user's request as the type of broadcast information is switched. Here, since the navigation information is related to the navigation of the vehicle, it is preferable that the basic part is common regardless of the user's request, but there is room to reflect the user's intention regarding the display of the navigation information. Seem. Therefore, updating the display specification of the navigation information in accordance with the switching of the information provision mode contributes to the convenience of the user.

The broadcast wave provided to the user in the other information provision mode may be received by all of the plurality of reception antennas. That is, by switching to another information provision mode, all broadcast information that can be received by the antenna connected to the information processing apparatus can be provided to the user.

  Further, in the information processing apparatus up to the above, in the case where the information processing device further includes a card slot portion into which a memory card storing a program for switching the information providing mode is inserted, the mode switching request portion is provided in the card slot portion. It may be determined whether or not a memory card is inserted, and an information provision mode switching request may be accepted according to the determination result. That is, the insertion of the memory card into the card slot portion is used as a trigger for switching the information providing mode. When such a trigger mode is adopted, the mode switching request unit may determine whether or not the memory card is inserted in the card slot unit when the information processing apparatus is activated. Good. Note that switching of the information provision mode triggered by the insertion of a memory card is merely an example, and does not preclude adoption of other types of triggers.

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.

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 region and displays the navigation region 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 mode switching>
In the navigation device 1, it is possible to switch the mode of providing information to the user via the navigation device 1, and the mode switching is performed mainly by the mode switching function unit 59 shown in FIG. Here, switching of the information provision mode in the navigation device 1 will be described with reference to FIG.

In the navigation apparatus according to the present embodiment, it is possible to switch between two information providing modes of “mass sale mode” and “renta mode”. These modes are information providing modes that are adopted in consideration of the form in which the vehicle on which the navigation device 1 is mounted is used. The “mass sales mode” is an information providing mode that is taken into consideration that a general individual user owns and uses the vehicle. In such a case, as a request of the individual user, the television is used as broadcast information. There is a tendency to request information by John broadcast waves. Further, it may be requested that the display specification of the navigation information displayed on the navigation device 1 can be arbitrarily set according to the preference of the individual user. On the other hand, the “renta mode” is an information providing mode that is taken into consideration that the vehicle is owned by a rental company and is provided to a borrower as a so-called rental car. In such cases, at the request of the owner, the rental car company,
There is a tendency that information by television broadcast waves as broadcast information is not desired for safer driving. Furthermore, it is preferable that the display specification of the navigation information displayed on the navigation device 1 is a fixed display specification in accordance with the intention of the rental company.

  In this way, there is an advantage that the type of information provided to the user of the vehicle is different depending on the usage form of the user, while the vehicle is used in a specific usage form (for example, as a rental car) for a certain period of time like the above-mentioned rental car Then, when it is desired to sell it as a used car to a general user, if the information providing mode by the navigation device 1 remains in the rental car mode, it cannot be said that the value as a used car is necessarily high. That is, since it is considered that the appropriate information provision mode provided to the user differs depending on the use form of the vehicle, at least the provision of the vehicle navigation information, which is a basic function as a navigation device, is maintained while providing the broadcast information Applicants have found a potential user's request to switch between.

  Therefore, the mode switching function unit 59 is formed in the control unit 20 in the navigation device 1 in order to meet this user request. The mode switching function unit 59 switches the information providing mode (for example, switching from the rental car mode to the mass sales mode) based on the presence of a memory card that can be accessed with the control unit 20 via the card memory interface 17. Here, FIG. 21 shows a detailed functional block diagram of the mode switching function unit 59. The mode switching function unit 59 includes a mode switching receiving unit 59a, a broadcast wave driver rewriting unit 59b, a display specification updating unit 59c, and a mode switching completion notification unit 59d.

  The mode switching accepting unit 59a is a functional unit that accepts an information provision mode switching request from a user. When the switching request is received by the function unit, switching of the information providing mode in the navigation device 1 is executed. The broadcast wave driver rewriting unit 59b is a functional unit that rewrites a driver program for processing the broadcast wave received via the antenna in the navigation device 1. As described above, in the navigation apparatus 1, an antenna corresponding to each broadcast wave as a hardware configuration and each broadcast wave so that three types of broadcast waves of AM broadcast, FM broadcast, and television broadcast can be received. A broadcast wave receiving unit 7 is provided for processing the received signal. The driver rewritten by the broadcast wave driver rewriting unit 59b is a driver program for controlling the broadcast wave receiving unit 7. The broadcast wave processing function unit 60 is formed in the control unit 20 by these driver programs (see FIG. 5), and the broadcast wave processing function unit 60 further includes the above-described broadcast waves (AM broadcast wave, FM broadcast). And an AM wave control unit 60a, an FM wave control unit 60b, and a television wave control unit 60c formed by a driver program corresponding to (waves, television broadcast waves) (see FIG. 23 described later).

  The display specification updating unit 59c is a functional unit that updates display specifications such as symbols and symbols displayed on the touch panel 21 of the navigation device 1 in accordance with the switching of the information provision mode. The display specification is updated in consideration of the usage pattern of the vehicle by the user who is the target when the information provision mode is switched. The mode switching completion notification unit 59d is a functional unit that notifies the user that the switching of the information provision mode in the navigation device 1 has been completed.

Here, the information providing mode switching processing (hereinafter simply referred to as “mode switching processing”) in the navigation device 1 executed by the mode switching function unit 59 formed in this way will be described with reference to FIG. To do. This mode switching process is executed when the navigation device 1 is activated. Therefore, in S101, the navigation device 1 is activated. Thereafter, in S102, it is determined whether or not a memory card is inserted into the card insertion slot 28. If a positive determination is made here, the process proceeds to S103, and if a negative determination is made, the process proceeds to S109. Further, in S103, it is determined whether or not the memory card inserted into the card insertion slot 28 is a mode switching card. Specifically, a program recorded in the memory card is searched to determine whether or not a predetermined installer for mode switching exists. Here, if a positive determination is made, the process proceeds to S104, and if a negative determination is made, the process proceeds to S107.

  In S107, it is determined whether or not the memory card is determined to be a navigation memory card for a memory card determined not to be a mode switching card. Specifically, it is determined whether or not navigation map data necessary for navigation of the vehicle by the navigation device 1 exists. If an affirmative determination is made here, the process proceeds to S108, and the normal vehicle navigation described above is started. On the other hand, if a negative determination is made in S107, the process proceeds to S109. In S109, an alarm notification is given to the user via the screen and sound of the touch panel 21. Specifically, when the process proceeds from S102 to S109, an alarm that a memory card necessary for starting the navigation device 1 is not inserted is issued, and when the process proceeds from S107 to S109, an official memory is issued. An alarm that a card other than the card is inserted is issued.

  As described above, when the navigation device 1 is activated by the processing described above, the determination result of whether or not the memory card storing the program necessary for switching the information providing mode is inserted into the card insertion slot 28. Based on the above, the information provision mode switching request from the user is accepted. Therefore, these processes are executed by the mode switching accepting unit 59a.

  Then, after an affirmative determination is made in S103, the driver program for the broadcast wave receiving unit 7 for processing the broadcast wave received in the navigation device 1 is rewritten in S104. This rewriting of the driver program is executed by the broadcast wave driver rewriting unit 59b, and the information providing mode of the navigation device 1 is substantially switched by the rewriting. Here, specific rewriting will be described with reference to FIG. FIG. 23 shows the configurations of the broadcast wave processing function unit 60 in the mass sales mode and the broadcast wave processing function unit 60 in the rental car mode side by side. The broadcast wave processing function unit 60 in the mass sales mode includes an AM wave control unit 60a, an FM wave control unit 60b, and a television wave control unit 60c. The broadcast wave processing function unit 60 in the rental car mode includes the AM wave control unit 60a, It consists only of the FM wave control part 60b. Therefore, when the mode switching from the rental car mode to the mass sales mode is performed, the television set is processed with respect to the broadcast wave processing function unit 60 in which only the driver program for AM wave and FM wave is recorded by the process of S104. Three types of driver programs including a wave driver program are recorded.

  As a result, in the rental car mode, information by television broadcasting that could not be provided to the user can be provided by switching to the mass sales mode. Specifically, in the rental car mode, since there is no television wave driver program, the television wave control unit 60c is not formed (see FIG. 23). Therefore, as shown in FIG. The “one segment” button is not displayed in the source selection area in the AV area displayed in FIG. When the rental car mode is switched to the mass sales mode by switching the information providing mode, a television wave control unit 60c is formed (see FIG. 23), and as shown in FIG. Thus, the user can obtain information via the television broadcast via the button. When the process of S104 ends, the process proceeds to S105.

In S105, the display specification in the navigation device 1 is updated in accordance with the switching of the information providing mode of the navigation device 1. Specifically, the display specification update unit 59c updates the appropriate display specification according to the new information provision mode switched in the process of S104. For example, in the rental car mode, as shown in FIG. 24, a “business office” button is provided in the navigation area of the touch panel 21 so that the borrower of the vehicle can immediately set the sales office of the rental car company that returns the vehicle for navigation purposes. It is displayed. In this state, when the information provision mode is switched by the process of S104, as shown in FIG. 9, the navigation of the touch panel 21 can be set so that the user can set the personal home immediately for navigation purposes. The “Home” button is updated and displayed in the area. As described above, the display related to navigation is also updated to an appropriate display in accordance with the switching of the information providing mode by the process of S105.

  Another example of such display specification update is shown in FIG. FIG. 25 shows a destination setting screen for vehicle navigation, as in FIG. This is a destination setting screen that is displayed when the navigation apparatus 1 adopts the rental car mode. On the other hand, the navigation apparatus 1 adopts the mass sales mode for the screen shown in FIG. This is a screen for setting a destination that is displayed when One of the differences between the two is that on the destination setting screen in the rental car mode (FIG. 25), a button for searching for a destination by “phone number” is displayed in the top row and large. In the destination setting screen (FIG. 17) in the mass sales mode, a button for searching for a destination by “address” is displayed in the top row and large. This is because a rental car borrower often uses a vehicle in a region away from a familiar area such as his / her own residential area or commuting area. Therefore, in the Lentaca mode, instead of making the “address” button stand out and displayed as in the mass sales mode, the “phone number” button is made prominent and displayed so that the borrower can easily find the destination. . That is, the display specifications related to navigation are different in consideration of the usage pattern of the vehicle in each mode.

  Therefore, by updating the display specifications in the navigation device 1 in S105, the destination screen shown in FIG. 25 and the destination screen shown in FIG. 17 are updated according to the switched new information provision mode. Also good. Thereby, the navigation information which is the original function of the navigation apparatus 1 can be provided to the user more smoothly. When the process of S105 ends, the process proceeds to S106.

  In S106, when the processes in S104 and S105 are completed, the user is notified on the touch panel that the switching of the information providing mode in the navigation device 1 has been completed. This notification is performed by the mode switching completion notification unit 59d.

  As described above, by switching the mode of providing information to the user by the broadcast wave in the navigation device 1 by the mode switching process, it is possible to provide appropriate information according to the purpose of use of the vehicle on which the navigation device 1 is mounted. At this time, the navigation device 1 has no change in the hardware configuration (receiving antenna). Further, by updating the display specifications related to navigation in accordance with the switching of the information providing mode, navigation display suitable for the usage mode of the vehicle of the user can be performed. This is extremely useful in the sense that the navigation apparatus 1 that can provide vehicle navigation information and broadcast information by broadcast waves can provide appropriate information to the user in each of various usage forms.
