JP 2003-137005 A

  By the way, the above-mentioned Patent Document 1 does not disclose any information display device for a vehicle provided with a navigation device, only that it can display different information images according to the angle of the line of sight with respect to one screen.

  In a conventional general navigation apparatus, when there are a plurality of destinations, waypoints, etc., a plurality of destinations and waypoints are sequentially set by one input means for one input screen. Therefore, when there are multiple occupants, each occupant will set their destinations in order, and when other occupants are too far away from the desired destination, etc. There are also situations in which it is difficult to set a desired destination or the like due to concern about the vehicle or interference from other passengers. Further, when a plurality of destinations are sequentially set, the setting time becomes longer according to the number of destinations to be set.

  The present invention has been made in view of such a point, and the object of the present invention is to provide a route reflecting a destination or waypoint desired by each occupant even when there are a plurality of destinations or waypoints. The object is to provide a vehicle information display device that can be set.

  In the present invention, each of a plurality of occupants can simultaneously set a destination for one display means without worrying about the intentions of other occupants.

  1st invention is provided in the position which can be visually recognized from several seats in a vehicle interior, The display means which can display a different information image in the some display direction corresponding to this seat, Controlling the display of the said display means And a control means for calculating a route to the destination set by the occupant and the information image displayed for each of the plurality of display directions, and the occupant performs an input operation on each information image. A vehicle information display device including a plurality of input means for storing and a storage means for storing various information is an object.

  The control means causes the display means to display the information image relating to the destination setting that prompts the occupant to set the destination in the plurality of display directions simultaneously and independently, and also relates to the plurality of destination settings. With respect to the information image, each of the input signals output from the plurality of input means corresponding to the information image is independently received, and a plurality of destinations are stored in the storage means based on the input signal. The route is calculated based on the destination, and the route is displayed on the display means.

  In the case of the above configuration, the information image related to the destination setting displayed in each display direction by the control unit via the display unit is the same as the operation performed by the occupant of destination setting, but for each display direction. When setting the destination, the display means simultaneously displays information images related to the independent destination setting in each display direction, and the destination displayed in each display direction. By providing the input means for performing the input operation independently on the information image related to the ground setting, the passengers positioned in the respective display directions can perform the destination input operation independently and simultaneously. At this time, since the information images related to the destination setting displayed in each display direction are independent from each other, an occupant located in each display direction sees only the information image related to the destination setting displayed in the display direction. The destination can be set while the destination is set, and each occupant can set the destination without being interfered by other occupants or interfering with other occupants. As a result, the occupant can set his / her desired destination without considering the destination set by other occupants. Further, even when a plurality of destinations are set, a plurality of passengers can set the destinations at the same time, so that the destination setting time can be shortened. Here, “simultaneously” means that each occupant performs the task of setting the destination in parallel, and the information images in each display direction are not switched at the same time, but the destination setting for each occupant. The display and input operation of the information image regarding are processed independently between the display directions.

  In a second aspect based on the first aspect, when the control means receives an input signal from the input means, the control means corresponds to the display means a destination based on the input signal. The information image is displayed in a display direction different from the display direction.

  In the case of the above configuration, when setting the destination, the destination is set independently of other display directions, but an input signal is input from the input means to the information image related to the destination setting. In other words, when the occupant sets the destination by the input means, the set destination is displayed in a display direction different from the display direction of the information image corresponding to the input signal. Other passengers can confirm the destination set. In other words, when setting the destination, it can be set without worrying about the intentions of other occupants, but when deciding the route finally, it is possible to consult with the occupants for consideration.

  In a third aspect based on the first aspect, the control means causes the display means to display the same information image including information on all the destinations stored in the storage means in the display directions. Shall.

  In the case of the above configuration, since one information image including information on all the set destinations is displayed in each display direction, each occupant can make a destination without worrying about the intentions of other occupants. After setting, the opportunity to confirm and examine all the destinations between the passengers can be secured, and a better route can be determined. At this time, since all the set destinations are represented on one information image, all the destinations can be grasped at a glance, and it is possible to easily make a determination for determining a route. Here, the “information about the destination” includes the name of the destination, the position of the destination, the distance to the destination, the required time to the destination, and the like. At least one of these is displayed on the information image.

  In a fourth aspect based on any one of the first to third aspects, the control means calculates one route based on a destination stored in the storage means.

  In the case of the above configuration, it is not necessary for the occupant to examine and set one route based on a plurality of destinations set by the input means and stored in the storage means, and one route is set by the control means. It can be set automatically.

  In a fifth aspect based on the fourth aspect, the control means calculates one route that passes through all destinations stored in the storage means.

  In the case of the above configuration, since one route is calculated using all the destinations stored in the storage means, one route reflecting the intentions of all the occupants who set the destination can be calculated. it can.

  In a sixth aspect based on the fourth aspect, the control means causes the display means to display an information image related to condition setting that prompts an occupant to set a condition for calculating the route, and an information image related to the condition setting. On the basis of the condition determined by the input signal output from the input means, one or more destinations including at least the final destination are selected from the destinations stored in the storage means, It is assumed that one route passing through the selected destination is calculated.

  In the case of the above configuration, by setting a condition when selecting a destination to be used for calculating one route from the destinations stored in the storage means, each occupant can select another occupant. Even if you set your destination freely without worrying about your intentions, because there are certain restrictions imposed by the conditions, unreasonable destinations that do not meet the conditions will be excluded, leading to the final destination. One more rational route can be determined. Here, “selecting a plurality of destinations” includes not only selecting some destinations from all destinations stored in the storage means but also selecting all destinations. . That is, as long as the conditions are met, all destinations stored in the storage means may be selected.

  In a seventh aspect based on the sixth aspect, the condition is related to a required time to the final destination.

  In the case of the above configuration, the destination used when calculating one route is selected from the destinations stored in the storage means based on the required time to the final destination set as a condition. . For example, a destination whose required time to the final destination exceeds the required time set as a condition is excluded when calculating the route. As another example, the destination is selected from the destinations stored in the storage means so that the required time to the final destination approaches the required time set as a condition, and the route is calculated. In this way, it is possible to cause the control means to calculate a route in which the required time to the final destination is a desired time.

  In an eighth aspect based on the sixth aspect, the condition relates to a degree of detouring with respect to the shortest route to the final destination.

  Here, “the degree of detour for the shortest route to the final destination” means the difference in the distance of the detour route to the distance of the shortest route to the final destination, the requirement of the detour route to the time required for the shortest route to the final destination Detours for the shortest route to the final destination, such as time differences, ratio of the distance of the detour route to the distance of the shortest route to the final destination, ratio of the time required for the detour route to the time required for the shortest route to the final destination Means the degree of In the case of the above configuration, a destination to be used when calculating one route is selected from each set destination based on the degree of detour with respect to the final destination set as a condition. For example, a destination whose degree of detour with respect to the final destination exceeds the degree of detour set as a condition is excluded when calculating a route. In this way, it is possible to cause the control means to calculate a route passing the destination where the degree of detour on the way to the final destination is a desired degree.

  In a ninth aspect based on the sixth aspect, the control means includes the final destination and the waypoint from the destinations stored in the storage means based on the condition determined by the input signal. Two or more destinations are selected, and one route passing through the selected destinations is calculated.

  In the case of the above configuration, a route point is set in addition to the final destination, and the route is set so as to surely pass through the route in the middle of the route to the final destination. In other words, by combining with other conditions, destinations other than the final destination and waypoints may be excluded when calculating one route from the set destinations. Only the route and the transit point are not excluded and are always included in the calculated route. Therefore, it is possible to cause the control means to calculate a route that always passes through the waypoint until the final destination is reached.

  According to the present invention, the display means and the control means display information images related to the destination setting for each display direction simultaneously and independently, and the input means allows the destination image to be displayed independently from each display direction. Therefore, each occupant can set a destination without worrying about the intentions of other occupants and without being interfered by other occupants. As a result, a situation in which any of the passengers cannot even set the destination is avoided, and a route reflecting the destination desired by each passenger can be set. In addition, since a plurality of destinations can be set simultaneously from each display direction by the input means, the destination setting time can be shortened.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(Overall configuration of information display device)

Thus, it is possible to determine execution of the button or the like selected by the cursor.

  In this way, the occupant operates the input switch 4 to perform input operations such as setting operations and selection operations in various information images to be described later. The driver seat side and passenger seat side input switches 41, 42 constitutes interface means together with the monitor 6. Here, in this information display device 1, since the monitor 6 can individually display different information images on the driver seat side and the passenger seat side, the monitor 6 is seated on the driver seat and the passenger seat. There will be two independent interface means for the occupant (see FIG. 3).

  The ROM 38 stores various programs executed by the CPU 2 and data of information images (see FIG. 7 and the like) displayed on the monitor 6. The RAM 39 temporarily stores various information, and the database 5 Stores various setting information for each passenger, as will be described later.

  Here, the RAM 39 and the database 5 may be configured by known information storage devices such as an HDD (Hard Disk Drive) and a flash memory. Further, these storage means 39, 5 may be configured by separate HDDs, flash memories, or the like. For example, the RAM 39 and the database 5 may be configured by the same single HDD, flash memory, or the like. The database 5 includes two types of display information registration DB 51 and display form registration DB 52 as will be described later. These two databases 51 and 52 are configured by the same single HDD, flash memory, or the like. Alternatively, it may be constituted by another HDD or flash memory.

  As shown in FIGS. 2 and 3, the monitor 6 is disposed at the center position in the vehicle width direction of the instrument panel 81 provided in the front of the vehicle interior, thereby occupant and passenger seat 92 seated in the driver seat 91. Each of the passengers seated on the screen can see the screen.

  Then, the CPU 2 of the information display device 1 receives an input signal from the input switch 4, reads a necessary program from the ROM 38, and performs various controls according to the program, that is, displays various information images on the monitor 6. Display control to be performed, interface control for receiving an input signal from the input switch 4 together with display of an information image, control for executing processing according to the received input signal, and the like.

  When executing the control, the CPU 2 stores the input information from the input switch 4 and the information acquired from the server 71 in the RAM 39 and the database 5 as necessary, or is stored in the ROM 38, the RAM 39 and the database 5. Control to read information, send / receive information via road-to-vehicle communication means 35, send / receive information via short-range communication means 36, and send / receive signals by ID transceiver 37 Do.

  Specifically, the CPU 2 executes display control for displaying on the monitor 6 a television image received by the tuner 34 as a television function, for example.

  In addition, the CPU 2 displays an e-mail acquired from the mobile phone 73 by short-distance wireless communication on the monitor 6 or vehicle failure information (diagnosis result of remote failure diagnosis) transmitted from the server 71 by road-to-vehicle communication. Display control for displaying on the monitor 6 is executed.

  Further, as a function of the navigation unit 32, the CPU 2 displays on the monitor 6 a display control for displaying a map around the current location on the monitor 6, and displays a destination setting screen for setting a destination for route guidance on the monitor 6. On the other hand, the interface control for prompting the destination setting input by the input switch 4 and the route setting control for setting the route based on the set destination are executed.

  In addition, as a browser function of the information display device 1, the CPU 2 displays various information acquired from the server 71 by road-to-vehicle communication, for example, a menu selection screen of a restaurant as will be described later, on the monitor 6 to the passenger. On the other hand, interface control for prompting selection input by the input switch 4 and processing according to the input content (in the case of a menu selection screen, order processing, etc.) are executed.

  Here, in the present embodiment, the monitor 6 is configured to be able to display different information images depending on the angle of the line of sight with respect to the screen. In the present embodiment, in particular, an occupant seated in the driver's seat 91 and a passenger seat Different information images are displayed in the display directions corresponding to the occupants seated in 92.

  That is, the monitor 6 includes a liquid crystal panel 60 as shown in FIG. 4, and the display surface of the monitor 6 has a fixed width and extends in the vertical direction (vertical direction in FIG. 4). And a second strip 62. These first and second belt-like portions 61 and 62 are alternately arranged in the vehicle width direction.

  In addition, a transparent cover 63 is disposed on the front surface side (vehicle interior side) of the liquid crystal panel 60. A first light shielding band 64 is provided on the surface of the transparent cover 63, and a second light shielding band 64 is provided on the back surface thereof. A light shielding band 65 is provided.

  The widths of the light shielding bands 64 and 65 are the same as the widths of the belt-like portions 61 and 62, and the first and second light shielding bands 64 and 65 are separated from each other by the same width as the vehicle width. It is formed at equal pitches in the direction. In addition, the first light shielding band 64 and the second light shielding band 65 are shifted in the left-right direction by a 1/2 pitch, whereby the light passage slits 66, 65 are arranged between the light shielding bands 64, 65. 67.

  Then, the CPU 2 displays an information image for the driver's seat on the first belt-shaped portion 61 and displays an information image for the passenger's seat on the second belt-shaped portion 62. The driver seat image is selectively viewed by the passenger 91a seated in the driver seat 91, and the passenger seat information image is selectively viewed by the passenger 92a seated in the passenger seat 92.

  With this configuration, for example, a map related to route guidance performed by the navigation unit 32 is displayed for the occupant 91a seated in the driver's seat 91, while a television program is displayed for the occupant 92a seated in the passenger seat 92. Can be displayed. In addition to displaying images of different information sources on the driver's seat side and the passenger seat side, that is, images related to different information, for example, images related to the same information source, that is, images related to a single information. However, it is possible to make the display form of the information image different between the driver's seat side and the passenger's seat side, or to display an interrupt only for a specific passenger, for example, the driver's seat side.

  In addition, if the same information image is displayed on the first and second belt-like portions 61 and 62, the information image visually recognized by the occupant 91a seated in the driver seat 91 and the information visually recognized by the occupant 92a seated in the passenger seat 92 are displayed. The images are the same. Therefore, the CPU 2 performs individual display control for individually controlling the driver seat side information image and the passenger seat side information image, and general display control for controlling the driver seat side information image and the passenger seat side information image in the same manner. It is supposed to switch.

(Modification regarding the configuration of the information display device)
In the monitor 6, if the first shading zone and the second shading zone provided on the transparent cover 63 are composed of liquid crystal and the shading zone can be made to appear and disappear by control, the shading zone is made to appear and operated. It is possible to switch between a state in which the information image is displayed only in the respective angular directions (display directions) of the seat direction and the passenger seat direction, and a state in which the information image is displayed regardless of the angular direction by eliminating the shading band. It becomes possible. That is, in the individual display control, the angle direction in which the information image is visually recognized is limited, and in the general display control, the angle direction in which the information image is visually recognized is not limited.

  Further, for example, the first light shielding band and the second light shielding band provided on the transparent cover 63 are configured by liquid crystal, and the position of the light shielding band can be changed by control, in other words, the position of the light passage slit can be changed. For example, the direction in which the information image is visually recognized can be changed.

  Further, depending on the configuration of the liquid crystal panel and the light passage slit, the angle direction in which the information image is visually recognized can be not only two directions of the driver seat side and the passenger seat side, but also three directions or more. . As a result, it is possible to display different information images for each of the passenger seated in the driver's seat, the passenger seated in the passenger seat, and the passenger seated in the rear seat.

  Furthermore, a monitor is arranged on the instrument panel for the front seat, and a monitor is arranged on the roof for the rear seat, and each monitor has different information images in the right direction and the left direction as described above. May be displayed. In this case, different information images can be displayed for each of the passenger seated in the driver's seat, the passenger seated in the passenger seat, the passenger seated in the right rear seat, and the passenger seated in the left rear seat.

  In addition, the monitor configured to be able to display different information images according to the angle of the line of sight with respect to the screen is not limited to the one using the light passage slit. For example, a configuration in which a deflecting element that deflects light from the liquid crystal panel in a plurality of directions may be provided on the surface side of the liquid crystal panel.

(Personal conformity display control)
As described above, the information display device 1 can display different information images on the driver seat side and the passenger seat side in the individual display control. By utilizing this fact, the information display device 1 according to the present embodiment changes the display form of the information image on the driver's seat side according to the occupant seated in the driver's seat, while the information image on the passenger seat side Control is performed to change the display mode according to the passenger sitting in the passenger seat. That is, the display form is changed by changing the size of characters in the information image or changing the color of the characters, thereby adapting the display form of the information image to a specific occupant (individual).

  The information display device 1 changes the information included in the information image on the driver's seat according to the passenger seated in the driver's seat, while the passenger's seat side changes according to the passenger seated in the passenger seat. Control to change information included in the information image is performed. That is, for example, control is performed such that an e-mail acquired from the mobile phone 73 is displayed only to the owner of the mobile phone 73 (the occupant who is the destination of the mail) and not displayed to other occupants.

  Thus, although there is one monitor 6, control (personal adaptation display control) is performed that is equivalent to a state in which a plurality of monitors are provided for each occupant and each monitor display is optimized for the occupant. .

  In order to perform such personal adaptation display control, it is necessary to specify which occupant is seated in which seat. In the information display device 1, the ID transmitter / receiver 37 described above and the ID transmission carried by the occupant are provided. The identification is performed by the machine 72.

  Hereinafter, personal adaptation display control in the information display apparatus 1 will be described with reference to the drawings. This control includes three controls including registration control, occupant position detection control, and individual display control, and each control will be described in turn.

(Registration control)
The registration control is control for previously registering the display form and display information of each occupant in the database 5, and this registration control is performed according to the flowchart shown in FIG. That is, FIG. 6 shows a flowchart of the registration control executed by the CPU 2. When the registration control is selected by the operation of the input switch 4 by the occupant, the CPU 2 reads out the ID corresponding registration screen from the ROM 38 and displays it as information. An image is displayed on the monitor 6 (step SA1). Each information image (FIGS. 7, 8, and 9) displayed on the monitor 6 in the registration control may be displayed in the same way on the driver seat side and the passenger seat side as the display in the general display control, or may be displayed individually. As a display in the control, it may be displayed only for the seat on the input switch 4 side where the input operation is performed.

  As shown in FIG. 7, this ID correspondence registration screen has buttons (ID1, ID2) for selecting IDs to be registered, buttons for selecting whether to set display information or display form (display information). Setting, display mode setting).

  It is determined which of the display information setting and the display form setting is selected by the operation of the input switch 4 by the occupant (step SA2). When the display information setting is selected, the process proceeds to step SA3, and the display form setting is selected. Sometimes the process proceeds to step SA6.

  In step SA3, the display information setting screen read from the ROM 38 is displayed on the monitor 6 to allow the occupant to make settings / inputs on this setting screen (see FIG. 8). The example of FIG. 8 shows a setting screen relating to “ID1”, and this setting screen includes three items of “mobile transfer mail information display setting”, “vehicle malfunction information display setting”, and “program reservation information display setting”. Is included.

  The mobile transfer mail information display setting is an item for setting whether or not the information of the mail received by the mobile phone 73 carried by the passenger is transferred to the information display device 1 and displayed on the monitor 6. That is, the information set here is unexpected information transmitted to a specific occupant.

  This mobile forwarding mail information display setting item includes a button for setting whether to display the forwarded mail information on the monitor 6 (transfer mail information display), and when displaying on the monitor 6 (when set to ON). A field (identification ID) for inputting an identification ID for identifying the mobile phone 73 for communication by the short-range communication means 36 and whether or not to display the mail information only for a specific occupant, in other words, mail And a button (displaying only ID1) for setting whether to display information by individual display control or general display control. In the illustrated example, the forwarded mail information is displayed on the monitor 6, the identification ID is input as “◯ × Δ”, and the mail information is set to be displayed only to the passenger of ID 1.

  Whether the vehicle failure information display setting displays on the monitor 6 information on an e-mail transmitted to the vehicle (information display device 1) when a failure is detected in the remote failure diagnosis executed by the server 71. This item sets whether or not. That is, the information set here is unexpected information transmitted to the vehicle.

  This vehicle failure information display setting item includes a button (vehicle failure information display) for setting whether or not to display mail information on the monitor 6, and whether or not to display the mail information only for a specific passenger. For example, a button for setting whether to display the mail information by individual display control or general display control (displaying only ID1) is included. In the example shown in the figure, the mail information is displayed on the monitor 6 and the mail information is displayed only to the passenger of ID1.

  The program reservation information display setting is an item for setting whether to display on the monitor 6 that a specific television or radio program starts. That is, the information set here is schedule information related to the occupant.

  This program reservation information display setting item includes a button (program information display) for setting whether or not to display program information on the monitor 6 and a program to be displayed on the monitor 6 (when set to ON). Input field for specifying (CH (for TV) / Hz (for radio), time, only once, every day or every day of the week) and whether to show program information only to specific passengers In other words, a button for setting whether to display program information by individual display control or general display control (displaying only ID1) is included. In the illustrated example, program information is displayed on the monitor 6, and a program of ○ CH (or Hz) starting at 12:00 every Friday is registered, and the program information is set to be displayed only to the passenger of ID1. Yes.

  The display information setting screen has “OK” and “RETURN” buttons. When the “OK” button is operated, the selection / input contents of each item performed on this display information setting screen are displayed. When it is confirmed and the “return” button is operated, the screen returns to the ID correspondence registration screen without confirming.

  Then, in step SA4, it is determined whether or not setting / input has been performed on the display information setting screen. If YES in step SA4, the setting / input content is registered as display information in step SA5. Register in DB51.

  In the following description, information related to the display information setting (transfer mail information, vehicle failure information, and program information) is collectively referred to as specific information.

  On the other hand, in step SA6, the display form setting screen read from the ROM 38 is displayed on the monitor 6, and the occupant performs setting / input on this setting screen (see FIG. 9). The example of FIG. 9 shows a setting screen related to “ID1”, and this setting screen includes five items of “font”, “font size”, “color”, “language”, and “screen”. Here, “font” is an item for setting the font of the character in the information image. Here, “square” and “round” are selectively set. Similarly, “font size” is an item for setting the size of characters in the information image, and here, one of “10”, “12”, “14”, and “16” is selectively set. ing. “Color” is an item for setting the color of characters in the information image, and here, “black” and “red” are selectively set. “Language” is an item for setting the language in the information image. Here, “Japanese” and “English” are selectively set. “Screen” is an item for setting a wallpaper in an information image, and is configured to selectively set “standard” and “floral pattern” here.

  As described above, the display form setting optimizes the form of the information image displayed on the monitor 6 to the visual characteristics (sight, color vision, etc.) of each occupant, or adapts the form of the information image to each occupant's preference. It is possible to

  In addition, the display mode setting screen is provided with buttons for “decision”, “return”, and “return to standard”. When the “decision” button is operated, each item performed on the display mode setting screen is displayed. When the selection / input contents are confirmed and the “return” button is operated, the screen returns to the ID registration screen without confirmation, and when the “return to standard” button is operated, each item is set to a predetermined content (default). Is done.

  Then, in step SA7, it is determined whether or not setting / input has been made on the display form setting screen. If YES in step SA8, the setting / input content is registered in display form in step SA8. Register in DB52.

  The ID correspondence registration screen (see FIG. 7) also includes an item for setting a condition for applying the contents set on the display information setting screen as a setting item related to display information setting. That is, an item for setting whether or not the contents set on the display information setting screen are applied only when seated in the driver's seat is provided. When “Yes”, the passenger (here, the passenger of ID1) The information set on the display information setting screen is applied only when is seated in the driver's seat, and the content set on the display information setting screen is not applied when the passenger is seated in a seat other than the driver's seat become. On the other hand, if “No”, the content set on the display information setting screen is applied regardless of which seat the occupant (ID1 occupant here) is seated. In this way, setting the conditions for applying the contents set on the display information setting screen is desirable to display information on the monitor 6 when the occupant is seated in the driver's seat, while the occupant is in the passenger seat. This is because the necessity of displaying information on the monitor 6 is scarce when sitting on the screen. In other words, when sitting in the passenger seat, information such as e-mail may be acquired through a mobile phone carried by the user, so that the conditions for applying the contents set on the display information setting screen can be set As a result, usability can be improved.

  In addition, the ID correspondence registration screen includes an item for setting whether to perform the mobile transfer function when the contents set on the display information setting screen are applied only when seated in the driver's seat, There is provided a column for inputting an address of the mobile phone 73 required for performing the transfer function (an address for sending an e-mail from the server 71 to the mobile phone 73). When the occupant is seated in a seat other than the driver's seat, the mobile transfer function does not display the transfer mail information, the vehicle malfunction information, and the program information on the monitor 6, and the mobile phone 73 that the occupant carries. It is a function to transfer to. In the example shown in the figure, ON is set and a mobile address is input. Note that the mobile transfer function here transmits an e-mail from the server 71 to the mobile phone 73, but unlike this, the e-mail information is sent from the information display device 1 to the mobile phone 73 by short-range wireless communication. May be.

  FIG. 10 shows the configuration of the display information registration DB 51 (FIG. 10 (a)) and the configuration of the display form registration DB 52 (FIG. 10 (b)). The contents set and input on each of the display information setting screen and the display form setting screen are stored in association with the target ID as key information.

(Occupant position detection control)
The occupant position detection control is control for identifying which occupant is seated in which seat by detecting the ID transmitter 72 at a predetermined timing. In other words, the occupant position detection control is control for associating the occupant ID, which is key information of the database 5, with the position (seat). This control is performed according to the flowchart shown in FIG.

  Here, as shown in FIGS. 1 and 3, the CPU 2 of the information display device 1 includes a wheel speed sensor 83 for detecting the vehicle speed based on the wheel speeds of the left and right front wheels, and doors on the driver side and the passenger side. Door sensors 84 that detect opening and closing are connected to each other so that signals can be exchanged, and detection signals from these sensors are input to the CPU 2. The detection signal of the wheel speed sensor 83 and the detection signal of the door sensor 84 are used to determine the detection timing of the ID transmitter 72 in the occupant position detection control.

  This occupant position detection control is the individual display control described later from when the door is unlocked, that is, immediately before the occupant gets on board, to when the door is locked when the vehicle is stopped, that is, when the occupant gets off. Performed independently.

  In FIG. 11, in step SB1, it is determined whether or not the door has been opened / closed based on the detection of the door sensor 84. If the door has been opened / closed, the process proceeds to step SB4. If the door has not been opened / closed, step SB2 is performed. Migrate to

  In step SB2, it is determined whether or not the vehicle is stopped based on the detection result of the wheel speed sensor 83. If the vehicle is in a stopped state, the process proceeds to step SB4. If the vehicle is not in a stopped state, the process proceeds to step SB2. The process proceeds to SB3.

  In step SB3, it is determined whether or not there is a manual operation, that is, whether or not an occupant position detection request has been made by operating the input switch 4. If YES, the process proceeds to step SB4, and there is no operation. If NO, return.

  In step SB4, a request signal is transmitted from the ID transmitter / receiver 37, and it is determined whether or not the ID transmitter 72 has responded to the signal (step SB5). Then, when the response is YES (ID information is detected), the process proceeds to step SB6, while when the response is not received (ID information is not detected), the process proceeds to step SB8.

  In step SB6, it is determined whether or not the detected position of the ID transmitter 72 corresponds to the seat. If YES, the process proceeds to step SB7, where the ID position information is stored in the RAM 39. If the answer is NO, the process proceeds to step SB8 where the ID position information is erased (not stored). Here, “the position of the ID transmitter 72 corresponds to the seat” refers to a case where it can be determined that the occupant is seated in the driver seat or the passenger seat.

  When the position of the ID transmitter 72 corresponds to the seat, the occupant ID and the seat are stored in the RAM 39 in association with each other. For example, information that ID1 is a driver seat and ID2 is a passenger seat is stored in the RAM 39.

  As described above, since the occupant position detection control is performed when the door is opened and closed, the occupant position detection is performed when the occupant gets on and when the occupant gets off. Considering that the passenger may move the seat in the passenger compartment when the vehicle is stopped, the passenger position detection control is also performed when the vehicle is stopped. This makes it possible to more accurately identify which occupant is seated where. Further, when the occupant and the display of the information image visually recognized by the occupant are not suitable due to a detection error or the like by the ID transceiver 37, the ID transceiver 37 is made to detect again by manual operation. Is possible.

(Individual display control)
The individual display control is based on the detection result of the occupant position detection control described above, and adjusts the display form of the driver seat side information image and the passenger seat side information image to the occupant according to the contents registered in the database 5 in the registration control. The information is individually changed and the information included in each information image is changed according to the occupant.

  This individual display control is performed according to the flowchart shown in FIG. The flowchart of FIG. 12 shows the main flow of the individual display control. Various data are read in step SC1, and display information determination control is performed in step SC2. In subsequent step SC3, display timing setting control is performed. In step SC4, display control of monitor 6 is performed based on the contents set in steps SC2 and SC3. Hereinafter, the control in each step of SC2, 3, 4 will be described with reference to the flowcharts shown in FIGS.

  FIG. 13 shows a flowchart of the display information determination control in step SC2. In this display information determination control, it is determined whether or not the specific information has been acquired.

  First, in step SD1, it is determined whether or not transfer mail information has been acquired. When the mail information received by the cellular phone 73 is acquired by short-range communication, the process proceeds to step SD4. When the mail information is not acquired, the process proceeds to step SD2.

  In step SD2, it is determined whether or not vehicle failure information has been acquired. If the vehicle failure information has been received from the server 71 by road-to-vehicle communication, the process proceeds to step SD4. If not, the process proceeds to step SD3. Migrate to

  In step SD3, based on the information registered in the display information registration DB 51 and the time information detected by the clock 33, it is determined whether or not the program information notification time has come, and the notification time has come. YES In the case of, the process proceeds to step SD4, and in the case of NO when the notification time is not reached, the process returns.

  In step SD4, the information is temporarily stored in the RAM 39 as specific information, and the process returns. At this time, in the RAM 39, which occupant is associated with the specific information (whether the passenger is ID1 or ID2) is also stored.

  FIG. 14 shows a flowchart of the display timing setting control in step SC3 of FIG. 12. In this display timing setting control, the timing for displaying the acquired specific information on the monitor 6 is optimally set according to various situations. .

  First, in step SE1, it is determined whether or not specific information is stored in the RAM 39. When YES is stored, the process proceeds to step SE2. On the other hand, when NO is stored, the process directly returns.

  In step SE2, it is determined whether or not the specific information is information for a driver (occupant seated in the driver's seat). If YES, the process proceeds to step SE3. If NO, the process proceeds to step SE4.

  In step SE3, it is determined based on the detection result of the wheel speed sensor 83 whether or not the vehicle is traveling. Thus, when the vehicle is traveling, the process proceeds to step SE5, while when the vehicle is not traveling, the process proceeds to step SE4.

  In step SE4, it is determined whether or not the information currently displayed on the monitor 6 (information displayed on the occupant side related to the specific information) is mail information. The process shifts to step SE6, and when the mail information is YES, the process shifts to step SE7. Similarly, in step SE5, it is determined whether or not the information currently displayed on the monitor 6 is mail information. If the information is not mail information, the process proceeds to step SE8. If the information is YES, step SE9 is performed. Migrate to

  In step SE6, the display timing is set when information is acquired. In step SE7, the display timing is set when the currently displayed information (that is, mail information) is changed. In step SE8, the display timing is stopped. In step SE9, the display timing is set when the currently displayed information is changed and the vehicle stops.

  That is, when displaying information to the driver, it is desirable that the vehicle is stopped, so the display timing of the specific information is set at least when the vehicle is stopped. Further, when the mail information is displayed on the monitor 6, it is considered that the occupant is reading the mail. Therefore, it is not preferable to display another specific information there (interrupt display). Therefore, when the information currently displayed on the monitor is a mail, the display timing is set when the mail display state is changed. Thus, the timing is set so that the specific information is waited to be displayed in steps SE7, SE8, and SE9, while the specific information is displayed on the monitor 6 without waiting in step SE6.

  FIG. 15 shows a flowchart of the display control in step SC4 of FIG. 12. In step SF1, it is determined whether or not the ID position information is stored in the RAM 39. When it is stored, that is, when each occupant and its seating position are specified, the process proceeds to step SF2, and when not stored, that is, when each occupant and its seating position are not specified, the process proceeds to step SF3.

  In step SF2, it is determined by referring to the display form registration DB 52 whether or not the display form setting corresponding to the occupant is registered. If the display form setting is registered, the process proceeds to step SF4. On the other hand, if NO is registered, the process proceeds to step SF5.

  In step SF4, the display form on the driver's seat side and / or on the passenger seat side is changed based on the information registered in the display form registration DB 52, and the process proceeds to step SF5. Therefore, when the display mode setting is not registered, the display mode of the monitor 6 is not changed.

  In step SF5, it is determined whether or not there is specific information in the RAM 39. If the specific information does not exist, the process proceeds to step SF14 to display normal information other than the specific information. The normal information includes, for example, a map around the current location as a screen displayed on the navigation unit 32, a television program, and the like.

  On the other hand, if YES in step SF5, the process proceeds to step SF6. In step SF6, it is determined with reference to the display information registration DB 51 whether or not the specific information is an object of individual display control. In other words, it is determined whether or not “individual display” is ON in the display information registration DB 51 (see FIG. 10). (Step SF12). Therefore, specific information is displayed on both the driver's seat side and the passenger seat side. On the other hand, when “individual display” is ON, it is determined that the target is a specific display and the process proceeds to step SF7.

  In step SF7, whether the occupant who is the object of the specific information is seated in the driver's seat, or if the occupant is not seated in the driver's seat, whether the occupant applies the individual display even when seated in the passenger seat (In the display information registration DB 51, NO is determined only when the driver's seat is seated). If YES in step SF7, the process proceeds to step SF8, whereas if NO, the process proceeds to step SF10.

  In step SF8, the display direction is set to the driver seat side or the passenger seat side in accordance with the registration contents of the display information registration DB 51, and in the subsequent step SF9, specific information is displayed at the timing set in the display timing setting control. (Specific display control).

  On the other hand, in step SF10, it is determined whether or not the mobile transfer function is ON. If it is ON, the process proceeds to step SF11. On the other hand, when it is OFF, the process proceeds to step SF13. In step SF11, the specific information is transmitted to the registered mobile address by e-mail. This electronic mail is transmitted to the mobile phone 73 via the server 71 by the road-to-vehicle communication means 35 as described above. Thus, the occupant can confirm the content of the specific information on the mobile phone 73.

  In SF3, it is determined whether or not there is specific information in the RAM 39. If NO in the absence of specific information, the process proceeds to step SF14 to display normal information other than the specific information, while there is specific information YES In step S13, the process proceeds to step SF13. .

  In step SF13, even if specific information exists, it is prohibited to display the specific information on the monitor 6. That is, when the ID position information does not exist (when it is not possible to specify which seat the occupant is seated on), it is prohibited to display the specific information on the monitor 6. This considers the function of not showing specific information to other passengers. Further, according to the contents registered in the display information registration DB 51, when the specific information is not displayed on the monitor 6 (not displayed even by individual display control), the specific information is naturally not displayed on the monitor 6.

  Next, what kind of information image is displayed on the monitor 6 by the above personal adaptation display control will be described with reference to the drawings.

  FIG. 16 shows an example in which the restaurant menu sent from the server 71 is displayed on the monitor 6. The upper diagram of FIG. 16 shows a state in which the information image is displayed on the monitor 6 by the general display control. In this case, the same information image is displayed on both the driver seat side and the passenger seat side. become.

  Here, when the display form setting exists in the display form registration DB 52 (YES in step SF2), the display form is changed, but in order to reduce the discomfort of the occupant due to the change of the display form, FIG. As shown in the upper diagram, the CPU 2 may interrupt and display a confirmation message on the monitor 6 and allow the occupant to selectively input whether or not to change the display form.

  If the change of the display form is selected by the operation of the input switch 4, the general display control is switched to the individual display control, thereby changing the display form (step SF4). As a result, as shown in the lower diagram of FIG. 16, the information image visually recognized from the driver's seat side and the information image visually recognized from the passenger seat side are different from each other. That is, although the information included in the information image is the same (here, a single information called a restaurant menu), the character size (font size) in the information image is mutually different according to the contents registered in the DB 52. To be different. In the illustrated example, the information image on the passenger seat side has a relatively small font size, whereas the information image on the driver seat side has a relatively large font size.

  By changing the display form in this way, various types of information can be provided in a form that is easy for the passenger to see. At this time, if the display form is changed in the information image visually recognized by the occupant seated in the driver's seat and the occupant seated in the passenger seat, even if the display form is easy for a certain occupant, May be difficult to see, in which case it will force other occupants to be hard to see. On the other hand, since the information display device 1 can display different information images for each of the passenger seated in the driver's seat and the passenger seated on the passenger seat side, the information display device 1 displays the information individually for each passenger. The form can be changed. As a result, the display form can be optimized for each occupant.

  In the lower diagram of FIG. 16, the information image on the driver's seat side and the information image on the passenger seat side are drawn side by side for easy understanding. The information image on the driver's seat side and the information image on the passenger seat side are visually recognized due to the difference in the direction of the line of sight, and the screen of the monitor 6 is not divided and displayed on the left and right. That is, the information display device 1 displays a plurality of information images at the same time, but the area of each information image is not reduced.

  FIG. 17 shows an example in which a map around the current location in the navigation unit 32 is displayed on each of the driver seat side and the passenger seat side.

  Here, when mail information is transferred from the mobile phone 73 carried by the passenger seated in the driver's seat to the information display device 1 (YES in step SF5 and YES in step SF6), the registered contents of the DB 51 are displayed. Correspondingly, an interrupt display for notifying the arrival of mail is performed only on the information image on the driver's seat side. At this time, no interruption display is performed on the information image on the passenger seat side. As a result, the occupant seated in the driver's seat can confirm the incoming mail and the content of the mail without being known by the occupant seated in the passenger seat. On the other hand, the passenger sitting in the passenger seat does not display information unrelated to himself / herself on the screen of the monitor 6.

  Thus, by changing the display information between the driver seat side and the passenger seat side, the occupant can acquire personal information without causing trouble to other occupants.

  Here, the interrupt display related to the incoming mail shown in the right diagram of FIG. 17 includes three buttons of “view full text”, “delete”, and “share”. It is possible to choose.

  When “view full text” is selected, the full text of the mail is displayed on the monitor 6 as an information image on the driver's seat side. When “erase” is selected, the interrupt display is erased.

  When “Share” is selected, the CPU 2 switches from the individual display control to the general display control, and displays the mail information on both the driver seat side and the passenger seat side. That is, the information display device 1 is configured to cancel individual display control in response to a passenger's request and display information displayed only to a specific passenger to other passengers. Thus, as in the above example, it is possible to satisfy the request to show the contents of the mail to other passengers, which is useful.

  Thus, according to the information display device 1 described above, it is possible to make the information image visually recognized by the occupant seated in the driver's seat different from the information image visually recognized by the occupant seated in the passenger seat. By setting the display form of the information image for each occupant, it is possible to visually recognize the information image in a form that is easy to see for each occupant and to provide a user-friendly interface to the occupant.

  In addition, according to the information display device 1 described above, since information to be displayed for each occupant can be set and information can be displayed only to a specific occupant, each occupant can receive information without causing trouble to other occupants. Can be acquired.

  Further, the display information and the display form are registered in the database 5 in advance, and the ID transceiver 37 and the ID transmitter 72 automatically detect which occupant is seated in which seat. Accordingly, since the personal adaptation display control is performed, it is not necessary to perform the settings for the personal adaptation display control every time the user gets on, for example, and the troublesomeness of such settings is eliminated.

  In addition, since the above-described personal adaptation display control is performed by one monitor 6, for example, unlike the case where a monitor is provided for each occupant, it is particularly effective in a vehicle interior that is a limited space. In addition, in the configuration in which the screen of the monitor 6 is divided and different information images are displayed on each of the divided screens, the size of each information image is reduced. On the other hand, the information display device 1 has the size of the screen (information image). This is also useful in that a plurality of information images can be displayed without being reduced.

  In addition, as a method of associating the occupant ID with the seat, the occupant operates the input switch 4 in addition to the method of detecting the ID signal of the ID transmitter 72 and its position by the ID transmitter / receiver 37 as described above. Thus, a method of inputting the correspondence between the occupant ID and the seat may be adopted. For example, the content “the passenger of ID1 is seated in the driver's seat” may be input by operating the input switch 4, and the CPU 2 may store the input content in the RAM 39.

(Modifications related to personal display control)
In the above embodiment, the display information setting and the display mode setting are registered in the database 5 in association with the occupant ID, and the ID signal and the position of the ID transmitter 72 are detected by the ID transmitter / receiver 37 as the ID detecting means. Thus, the occupant ID and the seat are associated with each other, but instead of this, the display information setting and the display form setting may be associated with the seat and registered in the database 5. This is particularly effective when the occupant seated in the driver's seat and the occupant seated in the passenger seat are determined.

  In this modification, the ID transmitter / receiver 37 can be omitted because it is not necessary to detect the ID.

  Next, an embodiment in which display information setting and display form setting are registered in association with a seat will be described with reference to FIGS.

  FIG. 18 shows a seat correspondence registration screen displayed on the monitor 6 in the registration control. A button for selecting a seat to be registered (driver's seat, front passenger seat), display information is set, or display mode is set. And a button for selecting whether to perform (display information setting, display form setting).

  When the display information setting is selected on the seat correspondence registration screen by the operation of the input switch 4 by the occupant, the display information setting screen is displayed on the monitor 6, and when the display configuration setting is selected, the display configuration setting screen is displayed on the monitor 6. Is displayed. Since the display information setting screen and the display form setting screen are almost the same as those in FIGS. 8 and 9, description thereof will be omitted.

  The seat correspondence registration screen includes an item “set to a pause state?”. This item is an item for setting whether to temporarily stop the setting registered in the database 5. In other words, this item is set when the person seated in the normal driver's seat sits in the passenger seat, or vice versa. When “Yes” is selected, the registered settings are temporarily stopped and “No” When is selected, the personal conformity display control is performed according to the registered settings without being stopped. The occupant manually sets this item when getting on or moving the seat.

  Further, in the modification, when the setting is paused, the specific information can be transferred to the mobile phone 73, and the item “mobile address” in the seat correspondence registration screen displays the mobile phone 73 of the transfer destination. It is an item to specify.

  In this modified example, as shown in FIG. 19, the contents set / input on the seat correspondence registration screen, the display information setting screen, and the display form setting screen are associated with the seat as the key information. Will be registered. 19A shows the configuration of the display information registration DB 51, and FIG. 19B shows the configuration of the display form registration DB 52.

  Further, in this modified example, since the key information is a seat, the key information includes position information. Therefore, occupant position detection control for associating key information with a position (seat) is unnecessary.

  Furthermore, in this modification, the main flow of the individual display control is the same as that in the above embodiment (see FIG. 12). Further, steps SC1, SC2, and SC3 in the main flow are the same as those in the above embodiment (see FIGS. 13 and 14), but the display control is different from that in the above embodiment.

  FIG. 20 shows a flowchart of display control according to the modification. In this flow, first, in step SG1, it is determined by referring to the display form registration DB 52 whether or not the display form setting corresponding to the driver seat and / or the passenger seat is registered. If NO, the process proceeds to step SG2, while if NO, the process proceeds to step SG3.

  In step SG2, the display form on the driver seat side and / or on the passenger seat side is changed based on the information registered in the display form registration DB 52, and the process proceeds to step SG3. Therefore, when the display mode setting is not registered, the display mode is not changed.

  In step SG3, it is determined whether or not there is specific information. When the specific information does not exist, the process proceeds to step SG10, and general information other than the specific information is displayed.

  On the other hand, if YES in step SG3, the process proceeds to step SG4. In step SG4, with reference to the display information registration DB 51, it is determined whether or not the specific information is an object of individual display control. When NO, which is not the target of specific display, the specific information is displayed by general display control (step SG9). Therefore, specific information is displayed on both the driver's seat side and the passenger seat side. On the other hand, when the answer is YES, the process proceeds to step SG5.

  In step SG5, it is determined whether or not the vehicle is temporarily stopped. If YES in step SG5, the process proceeds to step SG8. If NO in step ST5, the process proceeds to step SG6.

  In step SG6, the display direction is set to the driver seat side or the passenger seat side in accordance with the registered contents of the database 5, and in the subsequent step SG7, the specific information is displayed at the timing set in the display timing setting control (specific specification). Display control).

  On the other hand, in step SG8, the specific information is transmitted to the registered mobile address by e-mail. This e-mail is transmitted to the mobile phone 73 via the server 71. Thus, the occupant can confirm the content of the specific information on the mobile phone 73.

  As described above, the control according to this modification is particularly effective when the occupant seated in the driver's seat and the passenger seat is determined to be a specific person, and in that case, the same effects as those of the above-described embodiment are achieved.

  Further, in the modified example, it is not detected which occupant is seated in which seat, but is controlled uniformly in the direction of the seat (driver's seat and front passenger seat). Since display control can be temporarily stopped, inconvenience due to uniform control, for example, incompatibility between an occupant and a display form is solved.

  Furthermore, when the personal suitability display control is temporarily stopped, the specific information can be transferred to the mobile phone 73, so that the occupant can acquire the specific information without being known to other occupants, for example.

  Next, as described above, as an example of an application in the information display device 1 configured to be able to display different information images on the driver seat side and the passenger seat side, destination setting control which is a function of the navigation unit 32 The restaurant menu selection control that is a browser function will be described.

(Destination setting control)
The destination setting control is control for the occupant to set a destination related to route guidance performed by the navigation unit 32. In normal destination setting control, a single occupant operates the input switch 4 in an information image displayed on one monitor 6 to set a destination. For example, when setting a plurality of destinations (route points), the destinations are sequentially set.

  On the other hand, in the destination setting control according to the present embodiment, the information display device 1 can display a plurality (two) of information images on the driver seat side and the passenger seat side, and the input switch 4 can be operated. In view of the points provided on the seat side and the passenger seat side, it is possible for each of a plurality of passengers to set a destination at the same time and independently. That is, the CPU 2 displays an information image related to a single piece of information (the same information source) on the driver seat side and the passenger seat side simultaneously and independently on the monitor 6 and on the driver seat side and the passenger seat side. In response to the input information image, the input signals output from the driver side and passenger side input switches 41 and 42 are independently received, and the processing based on the input signals is executed independently (individual interface control). (First mode)). On the other hand, the CPU 2 displays the same information image relating to a single information (information source) on the monitor 6 regardless of the driver seat side and the passenger seat side, and also displays the same information on the driver seat side and the passenger seat side. It is also possible to receive an input signal output from the driver side or passenger side input switches 41 and 42 with respect to the information image, and execute processing based on the input signal (normal interface control (second mode)). In this normal interface control, an information image displayed on the driver's seat side and the passenger's seat side is displayed by one of the input switches regardless of the driver's seat side input switch 41 and the passenger seat side input switch 42. Perform input operations.

  FIG. 21 shows the main flow of destination setting control. First, when destination setting control is selected by operating the input switch 4, in step SH1, the destination setting screen is read from the ROM 38 and is displayed as an information image. Is displayed on the monitor 6. As shown in the upper diagram of FIG. 23, the destination setting screen includes three items “set by name”, “set by map”, and “set by phone number”. This is the same as a general destination setting screen. In the destination setting screen according to the present embodiment, the point different from the normal one is that an “individual destination setting” button is included, and when this button is selected, the passenger seated in the driver's seat and the passenger seat are displayed. Each seated passenger can individually set a destination on the destination setting screen. That is, in step SH2 of the flow shown in FIG. 21, it is determined whether or not the individual destination setting button has been pressed. If YES, the process proceeds to step SH3, whereas if NO, it is not pressed. Shifts to step SH4.

  In step SH3, individual browsing setting control (individual interface control) described later is executed, and in step SH4, normal setting control (normal interface control) is executed. Since this normal destination setting control is a general control, its description is omitted here.

  FIG. 22 shows a flow of individual browsing setting control (individual interface control). In step SI1, a destination setting screen is simultaneously displayed for each of the driver seat side and the passenger seat side. That is, the information included in the information image is the same as a single piece of information called destination setting, but displays a destination setting screen independent of each other. Then, in step SI2, processing corresponding to the switch operation is performed independently on each of the driver seat side and the passenger seat side. As a result, for example, as shown in the lower diagram of FIG. 23, an occupant seated in the driver's seat sets a destination on the map, while an occupant seated in the passenger seat sets a destination by name. .

  Then, if a destination is set in the driver side information image and the passenger side information image by operating the driver side and passenger side input switches 41 and 42, the CPU 2 switches from the input switches 41 and 42. Each destination setting signal as an input signal to be output is received independently, and destination information based on the destination setting signal is stored in the RAM 39.

  In step SI3, it is determined whether or not the destination has been set. When YES is set, the process proceeds to step SI4. When NO is set, the process returns to step SI2.

  In step SI4, the CPU 2 reads the destination information stored from the RAM 39, and calculates and sets a route to the destination set on each of the driver seat and the passenger seat based on the destination information. . Accordingly, as shown in the upper diagram of FIG. 24, a route to the destination (A stadium) set by the occupant (occupant 1) seated in the driver's seat is set, and the route is used as the driver's seat side information image. On the other hand, a route to the destination (C park) set by the occupant (passenger 2) seated in the passenger seat is set, and the route is displayed as a passenger seat side information image. At this time, each information image includes destination information set by other occupants. In other words, the information on the destination set by the occupant 2 (passenger 2 destination: C park) on the driver's seat side, and the information on the destination set by the occupant 1 (passenger 1 destination: A stadium) on the passenger seat side Is displayed (mutual display). By this mutual display, the destination set by the other occupants can be confirmed after setting the destination separately from the other occupants, and the opportunity to consider between the occupants is ensured when setting the route.

  The driver seat side information image is also provided with a “shared display” button. When this button is selected, the driver seat side information image and the passenger seat side information image are displayed from the individual display control. Switch to the same general display control. That is, when YES is determined in step SI5 in the flow of FIG. 22, shared display is performed in step SI6. As shown in the middle diagram of FIG. 24, the route to the destination set by each of the occupant 1 and the occupant 2 is superimposed on the monitor 6 and displayed on the map. Information on the route to the ground and the information on the route to the destination set by the occupant 2 are displayed. Thus, in the shared display, all the destinations stored in the RAM 39 in step SI2 and the route information to the destination are displayed on the same information image, and the information image is displayed on the driver seat side of the monitor 6 and Display the same on the passenger side. As a result, it is possible to ensure an opportunity for passengers to confirm and review information about all destinations and routes to the destinations. Furthermore, since all the destinations can be grasped at a glance, it is easier to make a determination for route setting than in the mutual display.

  This shared display information image is provided with a “composite setting” button and a “decision” button. When the “OK” button is selected, the process proceeds from step SI7 to SI8 (NO in step SI7). On the other hand, when the “composite setting” button is selected, the process proceeds from step SI7 to SI9 (in step SI7). YES). The “OK” button is a selection operation when selecting either one of the route information to the destination set by the occupant 1 and the route to the destination set by the occupant 2 and using it as the route guidance route It is a button to do. Therefore, in step SI8, the selected route is set as a route for route guidance by the navigation unit 32. Thus, the CPU 2 calculates one route based on the destination stored in the RAM 39. Then, route guidance by the navigation unit 32 is started.

  On the other hand, in step SI9, a composite route setting process is executed. The composite route setting process is a process of calculating a route including all the destinations set by the occupant 1 and the occupant 2. Such a process, that is, a process of setting a route including a plurality of destinations (route points) can employ various known methods, and thus description thereof is omitted here.

  When the composite route is set, an information image indicating the route is displayed on the monitor 6 (see the lower diagram of FIG. 24). By selecting and operating the “decision” button included in the information image, Route guidance by the navigation unit 32 is started. As described above, the CPU 2 can also calculate one route including all the destinations set by all the occupants (occupant 1 and occupant 2) stored in the RAM 39. Further, since the CPU 2 automatically sets one route based on a plurality of destinations, it is not necessary for the occupant to consider and set one route based on the plurality of destinations.

  In this way, the driver seat side information image and the passenger seat side information image can be individually controlled, and the input switch 4 (driver seat side) that can be operated on the information image corresponding to each information image. The information display device 1 having the passenger seat side input switches 41 and 42) can provide the occupant with a new destination setting method in which a plurality of occupants simultaneously and individually set destinations. .

  In addition, since multiple occupants can set destinations simultaneously and individually, each occupant does not care about the intentions of other occupants (without being interfered by other occupants or other occupants) ), You can set your desired destination. Thus, since a route including all of the plurality of destinations can be set based on the destination set by each occupant, a route reflecting the intention of each occupant can be set. Further, even when each occupant sets a destination, it is possible to set a route by selecting one of the destinations (step SI8), thereby increasing the degree of freedom of route setting. Furthermore, since a plurality of passengers can set the destination at the same time, the time for setting the destination can be shortened.

(Variation related to destination setting control)
In the above example, the two passengers, the occupant seated in the driver's seat (passenger 1) and the occupant seated in the passenger seat (passenger 2), each set a destination and combined the two destinations. However, as described above, the monitor 6 of the information display device 1 is configured to be able to display different information images for each of the passenger seated in the driver's seat, the passenger seated in the passenger seat, and the passenger seated in the rear seat. In addition, by providing the input switch 4 corresponding to each occupant, three or more occupants may set three or more destinations, and combine them to set a route.

  For example, the upper diagram of FIG. 25 shows a shared display information image when each of four occupants 1 to 4 sets a destination. In other words, occupant 1 sets A stadium as the destination, occupant 2 sets C park as the destination, occupant 3 sets D temple as the destination, and occupant 4 sets B skyscraper as the destination. ing. Thus, even when four occupants set the destination, in the shared display, the destination information of all four people stored in the RAM 39 and the route information to the destination are displayed on the same information image. The information image is displayed in the same manner regardless of the display direction of the monitor 6. In the individual browsing setting control in which each occupant sets a destination, when the occupant's destination is set, the information image of each occupant is displayed in the other three images as in the case of two occupants. Information on destinations set by human occupants will be included (mutual display).

  When the “composite setting” button is selected in this information image, a route passing through the four destinations is set as described above.

  Here, when a large number of destinations are set, an appropriate route may not be set if a route including all of them is set. Therefore, when setting a composite route, a passenger may be able to set conditions, and a route that satisfies the conditions may be set. That is, as shown in the upper diagram of FIG. 25, the CPU 2 displays a field for setting the complex condition on the monitor 6 (that is, displays an information image related to the condition setting), to the passenger. While prompting the setting of the composite condition and operating the input switch 4, based on the input signal output from the input switch 4, the composite condition (the final destination, the main destination, the main route, the required time or the detour described later) The degree may be stored in the RAM 39, and the route may be set so as to satisfy the composite condition read from the RAM 39 when the composite route is set.

  Here, the compound conditions include things related to destination selection, things related to time, things related to distance, and the like. Specifically, as a composite condition, a final destination is set in advance from a plurality of destinations (other destinations are used as transit points), and a main destination and / or a main route is selected from a plurality of destinations. Set the location (allowing other destinations to be excluded when setting the route), and set the required time in advance (if the route through all destinations exceeds the required time, one or Some destinations are excluded when setting the route), and an acceptable degree of detouring is preset (one or several destinations of the destinations are other destinations (final destination, main destination) And the like (excluding destinations and main waypoints), the destinations that are far away are excluded when setting the route). By combining these complex conditions, conditions based on the time required to reach the final destination, conditions based on the degree of detouring to the shortest route to the final destination, and detours for the shortest route to the final destination via the main route More detailed composite conditions such as conditions based on the degree can be set. The condition based on the time required to reach the final destination is that the time required to reach the final destination is shorter than the set time required or the time required to reach the final destination is close to the set time required. The conditions for selecting the ground are listed. As a condition based on the degree of detour for the shortest route to the final destination (or the shortest route to the final destination via the main route), the distance of the detour route and the shortest route to the final destination (or the main route) The shortest route to the final destination via the route, the required time of the detour route and the shortest route to the final destination (or the shortest route to the final destination via the main route) The difference in time, the ratio of the distance of the detour route to the distance of the shortest route to the final destination (or the shortest route to the final destination via the main route), the shortest route to the final destination (or the main route) For example, a condition for selecting a destination so that the ratio of the required time of the detour route to the required time of the shortest route to the final destination via the ground becomes smaller than the set difference or ratio. Such conditions are set by the operation of the input switch 4 by the passenger.

  In the example of FIG. 25, as the composite condition, the final destination is set to “C Park”, the required time is set to “within 60 minutes”, and the degree of detour is set to “medium”. When the compound route is set under this condition, the route to C park via D temple and B skyscraper is set, and A stadium has a large degree of detour when setting the route. Excluded examples are shown (see the lower figure of the figure). At this time, it is also possible to set “A Stadium” as the main route and set a route to C Park via A Stadium. The final destination and the main waypoint may be set by selecting a corresponding destination from the destinations set by each occupant and stored in the RAM 39, or the destinations stored in the RAM 39. In addition to the ground, it may be set separately as the final destination or the main route.

  As described above, when one route is set based on a plurality of destinations set by a plurality of passengers, an appropriate route can be set by enabling the setting of conditions.

(Restaurant menu selection control)
Next, restaurant menu selection control will be described. This control is, for example, a control related to a pre-reservation system that enables an order (including so-called drive-through) in a restaurant to be approached in advance in a vehicle.

  The configuration of the advance reservation system will be briefly described. The system includes an information display device 1 and a server 71. The server 71 has a function of distributing restaurant menu information and a function of receiving an order signal. . Further, the information display device 1 displays restaurant menu information on the monitor 6 by the browser function, and transmits an order signal to the server 71 according to the operation of the input switch 4.

  With this configuration, the advance reservation system places an advance order for the restaurant as follows. That is, when a restaurant menu browsing request is transmitted from the information display device 1 to the server 71 via the road-to-vehicle communication, the restaurant menu information is distributed from the server 71 to the information display device 1.

  In the information display device 1, the received restaurant menu is displayed on the monitor 6 using the browser function. The occupant operates the input switch 4 while looking at the restaurant menu displayed on the monitor 6 to select a desired dish and order the selected dish from the server 71.

  Based on the input signal from the input switch 4, the information display device 1 includes at least information on the selected dish and information for identifying the vehicle (or occupant) (vehicle ID, occupant ID in the case of an occupant). The order signal (transmission signal) that is included is transmitted to the server 71. The server 71 transfers the received order signal to the restaurant. Thus, it is possible to place an order before arriving at the restaurant, and it is not necessary to place an order after actually arriving at the restaurant.

  It should be noted that if the vehicle location information is included in the order signal, it will be possible to predict the time when the vehicle will arrive at the restaurant. Therefore, if the cooking is performed in accordance with the prediction, the arrival will occur. It is also possible to provide products (dishes) without having to wait for a long time later.

  Here, since the information display device 1 can perform switching between normal interface control and individual interface control, when the restaurant menu is displayed on the monitor 6, the normal interface control is performed. The same information image is displayed on the driver's seat side and the passenger's seat side, and dishes are selected and ordered according to the operation by the driver's seat or passenger's seat side input switches 41 and 42. On the other hand, when performing individual interface control, different information images are displayed on the driver's seat side and the passenger's seat side, and cooking is performed independently according to the operation by the input switches 4 on the driver's seat side and the passenger seat side. Can be selected. That is, with individual interface control, each occupant can select a dish while looking at the restaurant menu individually.

  Next, the restaurant menu selection control will be specifically described with reference to the flow shown in FIG. First, as described above, if display of a restaurant menu is requested by an operation of the input switch 4, a restaurant menu main screen is displayed on the monitor 6 in step SJ1. The restaurant menu main screen is configured, for example, as shown in the upper diagram of FIG. 27, and is provided with buttons for selecting “Western food”, “Japanese food”, and “Drink” and an “Individual browsing setting” button.

  In the following step SJ2, it is determined whether or not the above-described individual browsing setting button has been selected. If YES, the process proceeds to step SJ9. If NO, the process proceeds to step SJ3.

  Steps SJ3 to SJ8 are restaurant menu selection control by normal interface control, and in step SJ3, a restaurant menu screen is displayed on the monitor 6 (in this case, the same restaurant menu screen is displayed on the driver side and the passenger side). In step SJ4, processing corresponding to the switch operation of the input switch 4 (which may be either the driver seat side input switch 41 or the passenger seat side input switch 42) is executed. That is, on the restaurant menu screen, a process of downloading an information image of the next page from the server 71 in response to the selection operation of the “next” button, or information in response to the selection of a dish. The processing of updating the display of “order status” in the image is performed (see the middle diagram of FIG. 27. However, the middle diagram is a screen at the time of individual browsing setting, and “ID1 (ID2) in the normal browsing setting” There is no display such as "special menu").

  In step SJ5, it is determined whether or not the “end setting” button that has been operated when all settings (selection of dishes) have been completed. If NO, the process returns to step SJ3, while operating. If YES, the process proceeds to step SJ6.

  In step SJ6, a confirmation screen for confirming the selected content is displayed on the monitor 6 (see the right figure at the bottom of FIG. 27), and whether or not the “order” button provided on the confirmation screen has been operated. Is determined (step SJ7). If NO, the process returns to step SJ6. If YES, the process returns to step SJ8. In step SJ8, an order signal including information identifying the selected dish and the vehicle ID is used as a transmission means. The order process transmitted to the server 71 by means 35 is executed.

  In contrast to the normal restaurant menu selection control by interface control, steps SJ9 to SJ18 are restaurant menu selection control by individual interface control, among which steps SJ9 to SJ12 are steps related to driver side interface control. Steps SJ13 to SJ16 are steps relating to the interface control on the passenger seat side.

  Here, the driver side interface control in steps SJ9 and SJ10 is the same as the restaurant menu selection control by normal interface control in steps SJ3 and SJ4. That is, the restaurant menu screen is displayed on the monitor 6 as a driver's seat side information image (see step SJ9, the diagram on the right side of the center of FIG. 27), and processing corresponding to the switch operation of the input switch 4 is executed (step SJ10). Here, the information image relating to the restaurant menu transmitted from the server 71 in the driver side interface control is stored (cached) in the RAM 39 of the information display device 1.

  On the other hand, also in the interface control on the passenger seat side, the restaurant menu screen is displayed on the monitor 6 as the passenger seat side information image (see step SJ13, the diagram on the left side in the center of FIG. 27), and the process according to the switch operation of the input switch 4 Is executed (step SJ14). Here, the interface control on the passenger seat side is different from the interface control on the driver seat side, and the restaurant menu screen etc. is stored in the RAM 39 and the process of downloading the information image from the server 71 is performed. Absent. That is, the exchange of information with respect to the server 71 is performed according to the operation of the driver's seat side input switch 41, and is not performed even when the passenger's seat side input switch 42 is operated. Note that all information on the restaurant menu may be downloaded in advance and stored in the RAM 39 in accordance with the operation of the driver's seat side input switch 41. By doing so, the restaurant menu screen can be freely displayed in accordance with the operation of the passenger seat side input switch 41.

  The driver seat side information image and the passenger seat side information image during the selection control each include the selection status (order status) of other passengers (in the middle diagram of FIG. 27, the driver seat side information image (ID1 only) Menu) “ID2 order status” and information image on the passenger seat side (ID2 dedicated menu) “ID1 order status”).

  Then, in each interface control on the driver's seat side and the passenger seat side, it is determined whether or not the “end setting” button has been operated (steps SJ11 and SJ15). If NO, step SJ9 or Return to SJ13.

  Here, in the information display device 1, as will be described later, since the order process is configured to be performed according to the operation of the driver seat side input switch 41, in the driver seat side information image, the passenger seat side information image is displayed. The setting end button cannot be operated unless setting is completed in the interface control. Thus, when the “end setting” button is operated in the interface control on the passenger side, information for specifying the selected dish is stored in the RAM 39.

  If the “end of setting” button is operated in the interface control on the passenger side, “end of setting” is displayed in the column of “ID2 order status” in the information image on the driver side, so that the occupant seated in the driver's seat It becomes possible to recognize that the passenger seated in the passenger seat has completed the selection. In this state, the “end setting” button in the driver side information image can be operated. When the button is operated, the process proceeds from step SJ11 to SJ12, and the confirmation screen is displayed on the monitor 6 as the driver side information image. To do. At the same time, the confirmation screen is also displayed on the monitor 6 as a passenger side information image (see steps SJ12 and SJ16, the lower diagram of FIG. 27). Note that since the driver side information image includes the order status of the passenger in the passenger seat, the driver side passenger is waiting for the “end setting” button in the driver side information image to be operable. Meanwhile, it is possible to check the order status of passengers on the passenger side.

  Of these two confirmation screens, the confirmation screen on the driver's seat side is provided with an “order” button, whereas the confirmation screen on the passenger seat side is not provided with an “order” button. Therefore, only the driver on the driver's seat side can perform the order processing.

  Then, in the interface control on the driver's seat side, it is determined whether or not the “order” button has been operated (step SJ17), and if it is not operated, the process returns to step SJ12 and is operated. In this case, in step SJ18, an ordering process is executed in which the road-to-vehicle transmission means 35 transmits a batch of order signals including information specifying the selected dish and the vehicle ID to the server 71 in a batch. As a result, the information on the dishes selected by each of the two passengers is collectively transmitted to the server 71.

  In this way, by separately performing interface control on the driver's seat side and the passenger seat side, each occupant can freely browse the menu and select dishes at their own pace, as described above. .

  In addition, although each occupant individually browses the menu and selects a dish, each occupant goes to the restaurant together, so it is reasonable to perform the order processing collectively. Furthermore, when the restaurant adopts a drive-through configuration, it is possible to prepare goods for each vehicle and perform accounting. For this reason, the exchange between the restaurant and the vehicle can be simplified.

  Furthermore, in the case where the server 71 has a plurality of restaurant menus and when it is determined in the vehicle which restaurant menu browsing request is to be transmitted to the server 71, the information display device 1 is a normal one. The interface control allows all passengers to select a restaurant while looking at the same information image (for example, a list of restaurants or map information displaying restaurants around the vehicle). After the distribution, the information display device 1 allows each occupant to select a desired dish while looking at an independent information image (restaurant menu) by individual interface control. As described above, the normal interface control and the individual interface control can be switched according to the content and situation of the input operation, so that the convenience during the input operation can be improved.

(Variation regarding restaurant menu selection control)
In the above embodiment, in the individual interface control, the processing on the driver's seat side is the main, the processing on the passenger's seat side is the slave, and the exchange of information to the server 71 is performed only in accordance with the operation of the driver seat side input switch 41. For example, the processing on the driver's seat side and the processing on the passenger seat side may be performed independently. That is, the exchange of information with respect to the server 71 may be performed in accordance with any operation of the driver seat side input switch 41 and the passenger seat side input switch 42.

  FIG. 28 shows a flow of restaurant menu selection control according to a modification. This control is different from the flow shown in FIG. 26 in that information is exchanged with the server 71 individually in each of the driver side interface control and the passenger side interface control.

  First, the restaurant menu main screen (see FIG. 27) is displayed on the monitor 6 in step SK1, and it is determined in step SK2 whether the individual browsing setting button has been selected. When YES is selected, the process proceeds to Steps SK4 and SK10. When NO is selected, the process proceeds to Step SK3. In step SK3, restaurant menu selection control is performed by normal interface control. This corresponds to steps SJ3 to SJ8 in the flow of FIG. 26, and detailed description thereof is omitted here.

  On the other hand, steps SK4 to SK9 are driver side interface controls, and steps SK10 to SK15 are front passenger side interface controls. That is, steps SK10 to SK15, which are interface controls on the passenger seat side, are the same as steps SK4 to SK9, which are interface controls on the driver seat side. In steps SK4 and SK10, the restaurant menu screen is displayed on the driver seat side and the passenger seat. A side information image is displayed on the monitor 6, and in steps SK5 and SK11, processing corresponding to the switch operation of the input switch 4 is executed. Here, information is exchanged with the server 71 in each of the driver side interface control and the passenger side interface control.

  Then, in each interface control on the driver side and the passenger side, it is determined whether or not the “end setting” button has been operated (steps SK6 and SK12). Returning to SK10, if the operation is YES, the process proceeds to steps SK7 and SK13, respectively.

  Here, in the modified example, since the driver side interface control and the passenger side interface control are performed independently of each other, the setting end button can be operated independently in each information image. Yes. However, also in the modification, the driver seat side information image and the passenger seat side information image that are being subjected to selection control may each include the selection status (order status) of other passengers (see the middle diagram of FIG. 27).

  Then, in steps SK7 and SK13, confirmation screens are displayed on the monitor 6 as driver side images and passenger side information images, respectively.

  Here, although not shown, an “order” button is provided on each of the confirmation screens on the driver seat side and the passenger seat side, and “order” is provided in each of the interface control on the driver seat side and the interface control on the passenger seat side. ”Button is operated (steps SK8, SK14), and when NO is not operated, the process returns to step SK7 or SK13, and when operated is YES, in each of steps SK9, SK15. Then, the order processing including transmitting the order signal including the information for identifying the selected dish and the vehicle ID (may be the occupant ID) to the server 71 by the road-to-vehicle transmission means 35 is executed. As described above, in the modified example, information on the dishes selected by the two passengers is individually transmitted to the server 71. Performing order processing individually in this way is useful when it is desired to communicate with the outside as an individual occupant rather than as a vehicle, for example, when each occupant accounts individually.

  In the flow of FIG. 26, two modes of a batch order mode in which information on dishes selected by each occupant is ordered at once and an individual order mode in which each occupant orders individually may be provided. That is, as in the modification, the order process may be executed in the interface control on the driver side and the passenger side.

  Conversely, also in the flow of FIG. 28, two modes of a batch order mode and an individual order mode may be provided.

  In addition, although the structure which performs interface control separately on the driver's seat side and the passenger seat side using the browser function of the information display apparatus 1 was described as an example of the selection of the restaurant menu, this is the selection of the restaurant menu Needless to say, the present invention can be applied to other cases. For example, the present invention can be applied to an order for a rental video store.

  In the registration control as well, the ID corresponding registration screens are displayed simultaneously and independently on the driver seat side and the passenger seat side of the monitor 6 by the individual interface control, respectively, and the driver seat side and passenger seat side input switches 41 are displayed. , 42 may be used for independent input operations.

  Furthermore, as described above, the monitor 6 of the information display device 1 is configured so that different information images can be displayed for each of the passenger seated in the driver's seat, the passenger seated in the passenger seat, and the passenger seated in the rear seat. In addition, by providing the input switch 4 corresponding to each occupant, the above-described interface control may be performed individually for each of three or more occupants.

  In addition, this invention is not limited to the said embodiment, You may make it as follows. That is, in the said embodiment, although the input means is the input switch 4 which a passenger | crew operates by hand, it is good also as an input means by voice input, for example.

  As described above, the present invention can be provided in the passenger compartment because a route reflecting the destination or waypoint desired by each occupant can be set even when there are a plurality of destinations or waypoints. It is useful for a vehicle information display device.
