[Communications system]
Next, a communication system 100 to which the navigation device 1 described above is applied will be described with reference to FIG. FIG. 2 shows a schematic configuration of the communication system 100.

  The communication system 100 mainly includes a DSRC roadside device 91a, a DSSS roadside device 91b, a beacon roadside device 91c, a DSRC onboard device 92a, a DSSS onboard device 92b, a beacon onboard device 92c, and the navigation device 1. . FIG. 2 shows only the minimum components of the navigation device 1 when performing road-to-vehicle communication.

  The communication system 100 is a road-vehicle communication system that performs predetermined communication between the roadside devices 91a to 91c and the vehicle-mounted devices 92a to 92c. The DSRC roadside device 91a, the DSSS roadside device 91b, and the beacon roadside device 91c are each installed on a road or the like, and transmit information acquired from the outside to the DSRC onboard device 92a, the DSSS onboard device 92b, and the beacon onboard device 92c. .

  “DSRC” means Dedicated Short Range Communication, and “DSSS” means a driving safety support system (Driving Safety Support Systems). Hereinafter, information used in DSRC, information used in DSSS, and information used in beacon are referred to as “DSRC information”, “DSSS information”, and “beacon information”, respectively. Note that DSRC information, DSSS information, and beacon information do not indicate specific one information, but each include a plurality of types of information. For example, the DSRC information includes electronic signs and warning / warning information.

  The DSRC on-board unit 92a, the DSSS on-board unit 92b, and the beacon on-board unit 92c are mounted on the vehicle, respectively, and receive and receive information transmitted from the DSRC roadside unit 91a, the DSSS roadside unit 91b, and the beacon roadside unit 91c.

  Here, specific examples of DSRC information, DSSS information, and beacon information will be described with reference to FIG. The beacon information includes, for example, beacon emergency information and beacon immediate information. The beacon emergency information is emergency information, and the priority is “high”. The beacon immediate information is general information, and the priority is “low”. The DSRC information includes, for example, DSRC electronic signs, DSRC safe driving support information, and DSRC caution warning information. The DSRC electronic sign is general information, and the priority is “low”. The DSRC safe driving support information is the highest priority information, and the priority is “high”. The DSRC attention warning information is priority information, and the priority is “medium”. The DSSS information is priority information, and the priority is “medium”.

  Note that the above-mentioned beacon emergency information, beacon immediate information, DSRC electronic sign, DSRC safe driving support information, and DSRC caution warning information do not indicate specific one information, but each includes a plurality of types of information. .

  In addition, although the example which represents a priority with "high", "medium", and "low" was shown in FIG. 3, it is not limited to using such a priority. In another example, numerical priorities can be used. For example, “100”, “70”, “0” can be used as the priority. Moreover, it is not limited to using the priority prescribed | regulated in three steps, You may use the priority prescribed | regulated in four or more steps.

[Display control method]
Next, a display control method executed by the system controller 20 in the present embodiment will be described.

  In this embodiment, when two or more pieces of information to be displayed (DSRC information, DSSS information, beacon information, etc.) are acquired, the system controller 20 is acquired based on the priority and preference described above. The information to be preferentially displayed is determined from the information, and the screen corresponding to the determined information is preferentially displayed. Specifically, when the priorities of two or more pieces of information are different, the system controller 20 preferentially displays information having a high priority, whereas the priorities of the two or more pieces of information are the same. In some cases, information with high palatability is preferentially displayed.

  The reason why such a display control method is performed will be described with reference to FIG. FIG. 4 is a diagram for explaining a problem when the display control method according to the comparative example is performed.

  In the display control method according to the comparative example, information to be preferentially displayed is determined based only on the priority set for the DSRC information, the DSSS information, and the beacon information, and a screen corresponding to the determined information is displayed. Control to display with priority. Specifically, in the display control method according to the comparative example, when information having a lower priority than the information is interrupted while a screen corresponding to certain information is displayed, the current display screen is continued and interrupted. No information is displayed. On the other hand, when information having a higher priority than the currently displayed information is interrupted, the current display screen is switched to a screen corresponding to the interrupted information. In the display control method according to the comparative example, when information having the same priority as the information being displayed is interrupted, the current display screen is switched to a screen corresponding to the interrupted information.

  FIGS. 4A to 4D show screens displayed by the display control method according to the comparative example when information different from the information is interrupted during display of a screen corresponding to certain information. Specifically, FIGS. 4A and 4B show examples when information different in priority from the information being displayed is interrupted, and FIGS. 4C and 4D show the information being displayed. This example shows an example in which information having the same priority as that of the information is interrupted. 4A to 4D each show time in the horizontal direction.

  FIG. 4A shows an example when the DSRC electronic sign is interrupted while displaying the beacon emergency information. The interrupted DSRC electronic sign has a lower priority than the displayed beacon emergency information. Therefore, according to the display control method according to the comparative example, even if the DSRC electronic sign is interrupted, the beacon emergency information is displayed as it is, and the DSRC electronic sign is not displayed. In this case, basically, the DSRC electronic sign cannot be displayed. It should be noted that the display of the beacon emergency information itself is a result of preferential display of information with a high priority, so there is no particular problem.

  FIG. 4B shows an example in which beacon emergency information is interrupted when a DSRC electronic sign is displayed. The interrupted beacon emergency information has a higher priority than the displayed DSRC electronic sign. Therefore, according to the display control method according to the comparative example, when the beacon emergency information is interrupted, the display screen is switched from the DSRC electronic sign to the beacon emergency information. In this case, basically, after the display screen is switched, the DSRC electronic sign cannot be displayed. Note that the switching of the display screen itself is a result of preferentially displaying information with high priority, and thus there is no particular problem.

  FIG.4 (c) has shown the example when a DSRC electronic sign interrupts when displaying beacon immediate information. The interrupted DSRC electronic sign has the same priority as the displayed beacon immediate information. Therefore, according to the display control method according to the comparative example, when the DSRC electronic sign is interrupted, the display screen is switched from the beacon immediate information to the DSRC electronic sign. In this case, basically, the beacon immediate information cannot be displayed after the display screen is switched.

  FIG. 4D shows an example in which the beacon immediate information is interrupted when the DSRC electronic sign is displayed. The interrupted beacon immediate information has the same priority as the displayed DSRC electronic sign. Therefore, according to the display control method according to the comparative example, when the beacon immediate information is interrupted, the display screen is switched from the DSRC electronic sign to the beacon immediate information. In this case, basically, after the display screen is switched, the DSRC electronic sign cannot be displayed.

  Here, when information with the same priority as the information being displayed is interrupted, it is not tied to the priority when deciding which information to display, so it depends on the preference and necessity of the user. It is thought that the opportunity to see information freely should be given accordingly. However, in the display control method according to the comparative example, as shown in FIGS. 4C and 4D, the screen is forcibly switched to a screen corresponding to information (interrupted information) acquired later. Therefore, for example, the screen on which information that matches the user's preference or information necessary for the user is forcibly erased, and information that does not match the user's preference or information that is not necessary for the user may be displayed. It can be said that there is.

  In addition, there is a display control method that continues the current display screen and does not display the interrupted information when the information having the same priority as the information being displayed interrupts, but this method also relates to the comparative example. Problems similar to the display control method tend to occur. For example, in this method, information that does not match the user's preference or information that is not necessary for the user may continue to be displayed, and information that matches the user's preference or information that is necessary for the user may not be displayed.

  From the above, in this embodiment, when two or more pieces of information to be displayed at the same time are acquired, not only the priority but also the user's preference is taken into consideration, and the information is displayed with priority. Decide what information you want. Specifically, when the priorities of two or more pieces of acquired information are different, the system controller 20 preferentially displays information having a high priority, and on the other hand, priority is given to the two or more pieces of information. When the degrees are the same, information with high user preference is preferentially displayed. In this case, the system controller 20 displays a screen showing the contents of the information determined to be displayed preferentially. On the other hand, for information that has not been determined to be displayed preferentially, the system controller 20 displays an icon corresponding to the information without displaying a screen indicating the content of the information.

  Specifically, the system controller 20 performs the following display control when information different from the information is interrupted during display of a screen corresponding to certain information. In the following, a screen that is already displayed is referred to as an “existing screen”, and information used for the existing screen is referred to as “existing information”. Information interrupted during display of an existing screen (that is, received information) is called “interrupt information”, and a screen corresponding to the content of the interrupt information is called “interrupt screen”.

  When the interrupt information having a lower priority than the existing information is interrupted while displaying the existing screen, the system controller 20 continues to display the existing screen and does not display the interrupt screen. In this case, the system controller 20 displays an icon corresponding to the interrupt information. In other words, the system controller 20 notifies the user with an icon that another information has been interrupted. On the other hand, when the interrupt information having a higher priority than the existing information is interrupted while displaying the existing screen, the system controller 20 switches the display screen from the existing screen to the interrupt screen. In this case, the system controller 20 minimizes the existing screen and displays an icon corresponding to the existing information.

  On the other hand, when the interrupt information having the same priority as the existing information is interrupted while displaying the existing screen, the system controller 20 displays information having high user preference among the existing information and the interrupt information. Specifically, when the existing information has higher palatability than the interrupt information, the system controller 20 continuously displays the existing screen and displays an icon corresponding to the interrupt information. On the other hand, when the interrupt information has higher palatability than the existing information, the system controller 20 switches the display screen from the existing screen to the interrupt screen and minimizes the existing screen to cope with the existing information. Display icon.

  In the present embodiment, when the icon as described above is operated by the user, the system controller 20 displays a screen indicating the content of information corresponding to the icon. That is, the display screen is switched. In this case, the system controller 20 minimizes the existing screen and displays an icon corresponding to the existing information.

  Furthermore, in the present embodiment, when the user switches the display screen by operating the icon, the system controller 20 has a preference for information corresponding to the screen after switching (that is, information corresponding to the icon). Set high. This is because when the user performs an operation to switch the display screen, the information corresponding to the screen after the switching can be said to be information that meets the user's preference or that the user feels necessary. It is. Specifically, the system controller 20 uses a digitized point (hereinafter referred to as “switching point”) as the user's preference. In this case, the system controller 20 adds switching points each time the user performs an operation of switching the display screen. Therefore, the switching point set for one piece of information indicates the number of times the user has switched to the display screen corresponding to the information.

  According to the display control method according to the present embodiment described above, it is possible to appropriately determine information to be displayed preferentially from the acquired information based on the priority and the user's preference regarding a plurality of information. it can. In particular, when the priority of the acquired information is the same, it is possible to appropriately display information that suits the user's preference and information necessary for the user.

  Further, in the display control method according to the present embodiment, for information whose contents are not displayed among the acquired information, an icon corresponding to the information is displayed. Therefore, it is possible to give the user an opportunity to display all the acquired information. In this case, the user can switch the display screen by a simple operation such as pressing an icon.

(Display screen example)
Next, a display screen example according to the display control method according to the present embodiment will be described with reference to FIGS.

  FIG. 5 shows an example of a display screen displayed by the display control method according to the present embodiment when information having a lower priority than existing information is interrupted. In FIG. 5, beacon emergency information is illustrated as existing information, and a DSRC electronic sign is illustrated as interrupt information. In FIG. 5, the difference in the display screen is expressed by the difference in hatching.

  FIG. 5A shows a display screen A1 on which a screen A1a corresponding to beacon emergency information is displayed. FIG. 5B shows a display screen A2 that is displayed when a DSRC electronic sign is interrupted during display of the display screen A1 shown in FIG. As shown in FIG. 5 (b), since the interrupted DSRC electronic sign has a lower priority than the displayed beacon emergency information, the screen A2a corresponding to the beacon emergency information is continuously displayed and corresponds to the DSRC electronic sign. The screen to be displayed is not displayed. In this case, the icon A2b corresponding to the interrupted DSRC electronic sign is displayed. Such an icon A2b notifies the user that the DSRC electronic sign has been received.

  FIG. 5C shows a display screen A3 displayed when the icon A2b in FIG. 5B is operated by the user. As shown in FIG. 5C, when the user presses the icon A2b, a screen A3a indicating a DSRC electronic sign corresponding to the icon A2b is displayed. That is, the display screen is switched from the screen A2a corresponding to the beacon emergency information to the screen A3a corresponding to the DSRC electronic sign. In this case, the screen A2a corresponding to the beacon emergency information is minimized, and the icon A3b corresponding to the beacon emergency information is displayed. When the display screen is switched in this way, the switching point of the DSRC electronic sign is added.

  FIG. 6 shows an example of a display screen displayed by the display control method according to the present embodiment when information having the same priority as the existing information is interrupted. In FIG. 6, DSRC electronic signs are exemplified as existing information, and beacon immediate information is exemplified as interrupt information. Here, a case is considered where the DSRC electronic sign has a higher switching point than the beacon immediate information. This means that the number of times of switching the display screen to the DSRC electronic sign is greater than the number of times of switching the display screen to the beacon immediate information. In FIG. 6, the difference in the display screen is expressed by the difference in hatching.

  FIG. 6A shows a display screen B1 on which a screen B1a corresponding to the DSRC electronic sign is displayed. FIG. 6B shows a display screen B2 displayed when the beacon immediate information is interrupted during the display of the display screen B1 shown in FIG. As shown in FIG. 6B, since the interrupted beacon immediate information has a lower switching point than the currently displayed DSRC electronic sign, the screen B2a corresponding to the DSRC electronic sign is continuously displayed and corresponds to the beacon immediate information. The screen to be displayed is not displayed. In this case, an icon B2b corresponding to the interrupted beacon immediate information is displayed. Such an icon B2b notifies the user that beacon immediate information has been received.

  FIG. 6C shows a display screen B3 displayed when the icon B2b in FIG. 6B is operated by the user. As shown in FIG. 6C, when the user presses the icon B2b, a screen B3a indicating the beacon immediate information corresponding to the icon B2b is displayed. That is, the display screen is switched from the screen B2a corresponding to the DSRC electronic sign to the screen B3a corresponding to the beacon immediate information. In this case, the screen B2a corresponding to the DSRC electronic sign is minimized, and the icon B3b corresponding to the DSRC electronic sign is displayed. When the display screen is switched in this way, a switching point of beacon immediate information is added.

(Display control flow)
Next, a display control flow in the present embodiment will be described with reference to FIG. In this flow, when information different from the information is interrupted while the screen corresponding to certain information is displayed, it is determined which information is to be displayed preferentially, and the determined information is handled. A process for preferentially displaying the screen to be performed is performed. The flow is repeatedly executed by the system controller 20.

  First, in step S101, the system controller 20 determines whether information to be displayed has interrupted. Specifically, the system controller 20 determines whether at least one of DSRC information, DSSS information, and beacon information has been received. If the information is interrupted (step S101; Yes), the process proceeds to step S102. If the information is not interrupted (step S101; No), the process returns to step S101.

  In step S102, the system controller 20 determines whether a screen corresponding to the information is currently displayed. That is, it is determined whether there is an existing display. If there is an existing display (step S102; Yes), the process proceeds to step S104. On the other hand, when there is no existing display (step S102; No), the process proceeds to step S103. In this case, the system controller 20 displays a screen corresponding to the information interrupted in step S101, that is, displays an interrupt screen (step S103). Then, the process ends.

  In step S104, the system controller 20 determines whether the priority of the existing information is higher than the priority of the interrupt information. If the priority of the existing information is higher than the priority of the interrupt information (step S104; Yes), the process proceeds to step S105. In this case, the system controller 20 continues to display the existing screen and also displays an icon corresponding to the interrupt information, that is, notifies that another information has been interrupted with an icon (step S105). Then, the process ends.

  On the other hand, when the priority of the existing information is not higher than the priority of the interrupt information (step S104; No), that is, the priority of the existing information is lower than the priority of the interrupt information, or the priority of the existing information and the interrupt information. If the degrees are the same, the process proceeds to step S106.

  In step S106, the system controller 20 determines whether the priorities of the existing information and the interrupt information are the same. If the priorities are the same (step S106; Yes), the process proceeds to step S107. On the other hand, when the priorities are not the same (step S106; No), that is, when the priority of the existing information is lower than the priority of the interrupt information, the process proceeds to step S108. In this case, the system controller 20 switches the display screen from the existing screen to the interrupt screen, minimizes the existing screen, and displays an icon corresponding to the existing information (step S108). Then, the process ends.

  In step S107, the system controller 20 determines whether or not the interrupt information switching point is higher than the existing information switching point. Here, since the priorities are the same, the determination is performed using a switching point indicating the user's preference. When the interrupt information switching point is higher than the existing information switching point (step S107; Yes), the process proceeds to step S108. In this case, the system controller 20 switches the display screen from the existing screen to the interrupt screen, minimizes the existing screen, and displays an icon corresponding to the existing information (step S108). Then, the process ends.

  In contrast, if the interrupt information switching point is not higher than the existing information switching point (step S107; No), that is, if the existing information has a higher switching point than the interrupt information, the process proceeds to step S105. In this case, the system controller 20 continues to display the existing screen and also displays an icon corresponding to the interrupt information, that is, notifies that another information has been interrupted with an icon (step S105). Then, the process ends.

  According to the display control flow described above, it is possible to appropriately determine information to be preferentially displayed from the acquired information, based on the priority regarding the plurality of information and the user's preference. In particular, when the priority of the acquired information is the same, it is possible to appropriately display information that suits the user's preference and information necessary for the user.

  Next, a switching point setting flow will be described with reference to FIG. This flow is executed by the system controller 20 during or after execution of the above-described display control flow.

  First, in step S201, the system controller 20 determines whether or not an operation for switching the display screen has been performed by the user. Specifically, the system controller 20 determines whether or not an icon is pressed by the user in order to switch the display screen. If an operation for switching the display screen is performed (step S201; Yes), the process proceeds to step S202. If an operation for switching the display screen is not performed (step S201; No), the process returns to step S201.

  In step S202, the system controller 20 performs a process of adding switching points. Specifically, the system controller 20 performs a process of adding information switching points corresponding to the icon operated by the user. Then, the process ends.

  According to such a switching point setting flow, the user preference can be appropriately set for each piece of information.

[Modification]
In the above, when the priorities of two or more pieces of acquired information are different, information having a high preset priority is preferentially displayed, but the user's preference is given to the preset priorities. Information to be preferentially displayed may be determined by the added comprehensive evaluation. In this case, the preset priority may be digitized (pointed) as described above, and a switching point corresponding to the switching operation of the display screen may be added thereto to determine the priority in total. Conceivable. In addition to limiting the switching points to be added to the predetermined number of times immediately before or the predetermined period immediately before, setting a high point in the emergency information or the like that does not reach even if all the switching points in the limitation are added It is possible to prevent information that must be displayed with the highest priority, such as emergency information (for example, information that is defined in the standard) from being displayed.

  In the above, the display control method performed when one piece of information different from the information being displayed is interrupted has been described, but the same display control is also performed when two or more pieces of information different from the information being displayed are interrupted. The method can be done. In this case, information to be displayed preferentially is determined based on priority and preference from among three or more pieces of information including the information being displayed, and the screen corresponding to the determined information is prioritized. Can be displayed. For two or more pieces of information that have not been determined to be displayed preferentially, icons corresponding to the respective pieces of information can be displayed.

  In the above, DSRC information, DSSS information, and beacon information are shown as a plurality of pieces of information used for display. However, the use of these pieces of information is not limited. In another example, DSRC information, DSSS information, and beacon information may be used as information used for display, or navigation information may be used instead of using these information. In other words, regarding navigation information, when two or more pieces of information to be displayed are acquired, information to be preferentially displayed is determined based on priority and preference, and a screen corresponding to the determined information Can be controlled with priority. For example, information relating to a guide map is used as navigation information. As an example, there is information on a screen displayed at a branch point.

  In the above, the configuration including the vehicle-mounted device and the navigation device is shown as the vehicle-side device, but the application of the present invention is not limited to this. The present invention can also be applied to a configuration in which the vehicle-mounted device and the navigation device are integrated.

  In the above description, the configuration is shown in which information is input by the user operating the display unit 40 configured in a touch panel system, but the application of the present invention is not limited to this. The present invention can also be applied to a configuration in which a user inputs information using a key, a switch, a button, a remote controller, voice, or the like.

  The application of the present invention is not limited to navigation devices. In addition, the application of the present invention is not limited to the vehicle-mounted device. The present invention can also be applied to a terminal device such as a mobile phone.
