Description

  The present invention relates to an information display control device that controls the operation of an information display device, and more particularly to an information display control device having a cooperation (link) function with an external communication terminal.

  In recent years, information display devices having a communication function with communication terminals such as smartphones and mobile phones have been put into practical use. As such an information display device, an image or sound output by an application program (hereinafter simply referred to as “application”) running on a communication terminal is acquired and output from its own display unit or speaker, Some have a link function (for example, MirrorLink (registered trademark) function) that enables a cooperative operation with a communication terminal, such as receiving a user operation based on voice and controlling the communication terminal.

  In general, when an event such as an incoming call occurs during execution of an application in a communication terminal, the execution of the application is interrupted. At this time, the screen display of the communication terminal is usually switched from an image (application image) output by the application to an image notifying the occurrence of an event. Therefore, even if the information display device is linked to the communication terminal and displays an application image acquired from the communication terminal, when an event occurs in the communication terminal, transmission of the application image from the communication terminal is interrupted. In this case, the display on the information display device is also switched to an image that notifies the occurrence of an event at the communication terminal.

  For example, when an in-vehicle information display device is displaying a map output by a navigation application operating on a communication terminal, and there is an incoming call to the communication terminal, the display on the information display device is Switch to the incoming call screen. Then, the driver cannot see the map until the call is finished, and convenience is lowered.

  For example, in Patent Document 1 below, when an in-vehicle information display device displays a map of a navigation application of a communication terminal, the map is stored as needed, and when an event occurs in the communication terminal, the information display device Techniques have been proposed for continuing to display the map stored immediately before. According to this technique, even if there is an incoming call to the communication terminal, the map remains displayed on the information display device, so that the driver can continue to view the map.

JP 2011-254299 A

  The information display system as in Patent Document 1 is based on the premise that one communication terminal is linked to one information display device having one display unit (screen). For example, one information display device No consideration is given to the case where a plurality of display units are provided or the case where one communication terminal is linked to a plurality of information display devices. In consideration of such a case, it is considered that the display content desired for the information display device is different for each display unit.

  For example, consider a state where a driver's communication terminal is linked to an in-vehicle information display device having a display unit for a driver's seat and a display unit for a passenger's seat. In this state, when the screen of the communication terminal is displayed using the display unit for the driver's seat, the driver desires to display an image (event image) for notifying an event that has occurred in his / her communication terminal. However, when displaying the screen of the communication terminal using the display unit for the passenger seat, the driver may not want to display the event image of his / her communication terminal. In particular, if the event image contains personal information (for example, the name and phone number of the caller on the incoming call screen), the event image of the communication terminal can be seen by others from the viewpoint of privacy protection. Not desirable.

  SUMMARY An advantage of some aspects of the invention is to improve the convenience of an information display system having a plurality of display units.

An information display control device according to the present invention acquires a communication unit that communicates with a communication terminal, an image of an application running on the communication terminal, and event occurrence information on the communication terminal via the communication unit, For each display device, an image processing unit capable of displaying an application image and an event image indicating the occurrence of the event on the display device, a communication unit with which the communication unit communicates according to a setting by the user, and A restriction information storage unit that stores a restriction information table in which communication terminals that permit display of event images are registered, and the control unit is a communication terminal that is not registered in the restriction information table based on the restriction information table Table of events to limit the display to the image display device, the control unit further includes, according to a predetermined condition, the application of the image Limitations and performs a operation limitation for the application of the image.

  According to the present invention, a user can select which of a plurality of display devices displays an application image and an event image of a communication terminal according to the purpose. For example, in the in-vehicle information display control device, the event image of the driver's communication terminal is displayed on the display device for the driver's seat, the event image of the passenger in the passenger seat is displayed on the display device for the passenger seat, etc. A display in consideration of the privacy protection of the owner of the communication terminal becomes possible, and convenience is improved.

The operation unit 32 is a user interface of the communication terminal 30, and the user can perform operations on applications and events using the operation unit 32. The control unit 33 executes a control program for the communication terminal 30 to control basic functions (communication function, call function, etc.) of the communication terminal 30, and executes various applications to Various functions can be performed on the communication terminal 30.

  The information display control device 10 according to the first embodiment displays an event image on the first image display device 21a or the second image display device 21b when an event occurs in a specific communication terminal 30. When an event occurs in the communication terminal 30, display of the event image is restricted.

  In the storage unit 18 of the information display control device 10, the display contents of the first and second image display devices 21a and 21b are restricted (display restriction), and the operations of the first and second operation input devices 23a and 23b are restricted (display restriction). A restriction information table 184 in which conditions for performing (operation restriction) are registered is stored. In the restriction information table 184 of the first embodiment, a list of communication terminals (event image permission terminals) that permit display of event images is registered for each image display device connected to the information display control device 10. FIG. 2 is a diagram illustrating an example of the restriction information table 184 according to the first embodiment. FIG. 2 shows an example in which the communication terminal A is registered as the event image permission terminal of the first image display device, and the communication terminals B and C are registered as the event image permission terminal of the second image display device.

  The control unit 11 permits display of an event image when an event occurs in the communication terminal 30 registered as the event image permission terminal, but if an event occurs in other communication terminals 30, Limit the display. The event image permission terminal is set for each image display device connected to the information display control device 10. Therefore, the communication terminal 30 that is permitted to display the event image differs depending on which image display device is selected.

  The user of the information display control device 10 registers in advance in the restriction information table 184 the communication terminal 30 that permits the display of the event image for each image display device. The information on the communication terminal 30 registered in the restriction information table 184 may be any information as long as it is information (identifier) that can identify each communication terminal 30. Examples of such an identifier include an IMEI (International Mobile Equipment Identity) number, a MAC address (Media Access Control address), a telephone number, and the like of the communication terminal.

  Next, the operation of the information display system according to Embodiment 1 will be described. In the following description, the information display control device 10, the first image display device 21a, the second image display device 21b, the audio output device 22, the first operation input device 23a, and the second operation input device 23b are all in-vehicle devices. The communication terminal 30 is assumed to be a smartphone.

  The first image display device 21a and the first operation input device 23a are configured as one touch panel ("first touch panel device 212a" described later), and the second image display device 21b and the second operation input device 23b are also one. It is assumed that the touch panel is configured as a touch panel ("second touch panel device 212b" described later). Similarly, the display unit 31 and the operation unit 32 of the communication terminal 30 are also configured as one touch panel (touch panel unit 312).

  Further, a navigation application that performs route guidance is illustrated as an application that operates on the communication terminal 30, and an incoming call is illustrated as an event that occurs in the communication terminal 30. However, the application of the present invention is not limited to the combination of the application and the event. For example, the communication terminal 30 application may be a browser, an image viewer, a moving image reproduction application, or the like, and an event that occurs in the communication terminal 30 may be an incoming e-mail or the like.

  First, an outline of the cooperation (link) function between the information display control device 10 and the communication terminal 30 will be described. Here, it is assumed that the first image display device 21a is selected from the first and second image display devices 21a and 21b according to user settings.

  When the information display control device 10 and the communication terminal 30 are physically connected by wire or wireless and a link is established by both communication, the first image display device 21a (first touch panel) selected by the user as shown in FIG. The same image as the display unit 31 (touch panel unit 312) of the communication terminal 30 is displayed on the device 212a). The unselected second image display device 21b (second touch panel device 212b) is in a non-display state.

  While the information display control device 10 and the communication terminal 30 are linked, contents such as images and sounds output from the communication terminal 30 are transmitted to the information display control device 10, and the information display control device 10 transmits the contents to the first content. The image can be output using the image display device 21a and the audio output device 22.

  Further, the user operates the first operation input device 23a (first touch panel device 212a) while the information display control device 10 and the communication terminal 30 are linked, thereby operating the operation unit 32 (touch panel) of the communication terminal 30. The communication terminal 30 can be remotely operated with the same feeling as operating the unit 312). The operation unit 32 of the communication terminal 30 can be operated even while the link is established, and the communication terminal 30 can be operated from the operation unit 32 and the first operation input device 23a.

  For example, when the user touches the “navigation” icon displayed on the first touch panel device 212a from the state illustrated in FIG. 3, the communication terminal 30 performs the same operation as when the touch panel unit 312 of the communication terminal 30 is operated. The navigation application starts. Then, as shown in FIG. 4, the image (here, a map) of the application is displayed on the touch panel unit 312 of the communication terminal 30, and at the same time, the same image as the touch panel unit 312 of the communication terminal 30 is also displayed on the first touch panel device 212a. Is displayed. For example, when the application outputs a voice for route guidance, the voice is output from the voice output device 22 connected to the information display control device 10.

  In this way, in a state where the information display control device 10 and the communication terminal 30 are linked, the information display control device 10 and the communication terminal 30 perform an operation in cooperation with each other.

  Next, the operation of the information display control device 10 when a predetermined event occurs in the communication terminal 30 during the link with the communication terminal 30 will be described.

  FIG. 5 is a flowchart showing a display control operation of the information display control apparatus 10 according to the first embodiment when an event occurs in the communication terminal 30 being linked.

  For example, when an incoming call event occurs in the communication terminal 30 from the state shown in FIG. 4, the information display control device 10 refers to the restriction information table 184 to determine the first image display device 21a that is selected by the communication terminal 30. It is confirmed whether it is an event image permission terminal (step S11).

  When the communication terminal 30 is the event image permission terminal of the first image display device 21a (YES in step S11), the information display control device 10 displays the event image on the first image display device 21a as shown in FIG. (Step S12).

  Here, as an event image, an example is shown in which an image of an incoming call screen composed of characters representing the name and telephone number of a caller and operation buttons (icons) of “call start” and “hold” is displayed. . The event image also functions as a user interface, and the user can start a hands-free call using the communication terminal 30 by touching the “call start” button of the event image.

  When the communication terminal 30 is not the event image permission terminal of the first image display device 21a (NO in step S11), the information display control device 10 maintains the display of the application image on the first image display device 21a as shown in FIG. (Step S13). However, since the transmission of the application image from the communication terminal 30 is interrupted during the event occurrence, the application image (stored application image) immediately before the event occurrence stored in the image storage unit 14 is stored in the first image display device 21a. Display.

  Even if the display of the event image of the communication terminal 30 is restricted by the first and second image display devices 21a and 21b, the owner of the communication terminal 30 sees the event image on the display unit 31 of the communication terminal 30. In addition, since the communication terminal 30 can be operated using the operation unit 32, there is no problem in using the communication terminal 30.

  On the other hand, when the second image display device 21b is selected by the user setting, when the link between the information display control device 10 and the communication terminal 30 is established, the application image output by the communication terminal 30 as shown in FIG. Is displayed on the second image display device 21b (second touch panel device 212b). In this case, by operating the second operation input device 23b (second touch panel device 212b), the user operates the communication terminal 30 with the same feeling as operating the operation unit 32 (touch panel unit 312) of the communication terminal 30. Can be operated remotely. At this time, the communication terminal 30 can be operated from either the operation unit 32 or the second operation input device 23b.

  For example, when an incoming call event occurs in the communication terminal 30 from the state shown in FIG. 8, the information display control device 10 refers to the restriction information table 184 to determine the second image display device 21b currently selected by the communication terminal 30. It is confirmed whether it is an event image permission terminal (step S11 in FIG. 5).

  When the communication terminal 30 is the event image permission terminal of the second image display device 21b (YES in step S11), the information display control device 10 displays the event image on the second image display device 21b as shown in FIG. (Step S12).

  When the communication terminal 30 is not the event image permission terminal of the second image display device 21b (NO in step S11), the information display control device 10 maintains the display of the application image on the second image display device 21b as shown in FIG. (Step S13). Also at this time, since the transmission of the application image from the communication terminal 30 is interrupted during the occurrence of the event, the stored application image is displayed on the second image display device 21b.

  In the information display system of the present embodiment, the communication terminal 30 that is different for each image display device in the restriction information table 184 can be registered as an event image permission terminal. That is, the communication terminal 30 that permits the display of the event image can be changed for each image display device.

  When the information display control device 10 of Embodiment 1 is mounted on a vehicle and the first image display device 21a is arranged on the driver's seat side and the second image display device 21b is arranged on the passenger seat side, the communication terminal 30 of the driver is set. It is effective to use the event image permission terminal of the first image display device 21a and the passenger communication terminal 30 in the passenger seat as the event image permission terminal of the second image display device 21b.

  For example, consider a case where the driver's communication terminal 30 is linked to the information display control device 10. In that case, when an application image of the driver's communication terminal 30 is displayed on the first image display device 21a on the driver's seat side as shown in FIG. 4, when an event occurs in the communication terminal 30, FIG. Event images are displayed as follows. Thereby, high convenience for the driver is obtained.

  However, when the application image of the driver's communication terminal 30 is displayed on the second image display device 21b on the passenger seat side as shown in FIG. 8, even if an event occurs in the communication terminal 30, FIG. Event images are not displayed. Thereby, the privacy of the driver can be protected.

  Conversely, consider a case where the passenger's communication terminal 30 in the passenger seat is linked to the information display control device 10. In that case, when the application image of the communication terminal 30 of the passenger in the passenger seat is displayed on the first image display device 21a on the driver's seat side as shown in FIG. 4, an event occurs in the communication terminal 30. However, the event image is not displayed as shown in FIG. Thereby, the privacy of the passenger in the passenger seat can be protected.

  However, when the application image of the passenger's communication terminal 30 in the passenger seat is displayed on the second image display device 21b on the passenger seat side as shown in FIG. 8, when an event occurs in the communication terminal 30, An event image is displayed as shown in FIG. Thereby, high convenience is obtained for the passenger in the passenger seat.

  In the above description, the first and second image display devices 21a and 21b have been described as separate display devices. However, the first and second image display devices 21a and 21b use two images using one screen. May be realized by a split view monitor that displays in different directions (for example, the driver seat side and the passenger seat side).

  Further, although the first and second operation input devices 23a and 23b are shown as individual devices, they may be configured as a single operation input device. That is, the single operation input device may be switched to an operation mode that functions as the first operation input device 23a or an operation mode that functions as the second operation input device 23b. For example, when the first image display device 21a is selected, the operation mode functions as the first operation input device 23a, and when the second image display device 21b is selected, the operation mode functions as the second operation input device 23b. It is good to be.

  In the above description, an example is shown in which the confirmation whether or not the communication terminal 30 is the event image permission terminal of the selected image display device is performed at the time of the event occurrence, but before the occurrence of the event (for example, when the link is established, The confirmation may be completed when the image display device is selected.

<Embodiment 2>
In the second embodiment, an information display system is proposed in which display restrictions on application images and operation restrictions on application images can be performed by different control methods for each image display device. The configuration of the information display system according to Embodiment 2 is the same as that shown in FIG. Moreover, in Embodiment 2, the information display control apparatus 10 shall be mounted in a vehicle.

  However, attribute information of each image display device connected to the information display control device 10 is registered in the restriction information table 184 stored in the storage unit 18. FIG. 11 is a diagram illustrating an example of the restriction information table 184 according to the second embodiment. In the restriction information table 184, attribute information indicating the installation location in the vehicle (driver's seat, passenger seat, rear seat, etc.) is registered for each image display device. The number of image display devices connected to the information display control device 10 may be arbitrary, but in FIG. 11, three image display devices (first to third image display devices) are connected to the information display control device 10. An example is shown.

  The information display control device 10 changes the degree of application image display restriction and operation restriction according to the attribute of the application running on the communication terminal 30. The degree of display restriction and operation restriction is expressed by restriction levels 1 to 3, and the value of the restriction level is defined for each attribute of the application. FIG. 12 shows an example of the restriction levels of applications that run on the communication terminal 30.

  Assume that the relationship between the application restriction level, the application image display restriction, and the operation restriction is defined as shown in FIG. In other words, the application with the restriction level “1” is not subjected to display restriction or operation restriction of the application image regardless of which image display device in the vehicle is selected. An application with a restriction level of “2” restricts the operation of the application image while the vehicle is running when the driver's seat image display device is selected (display of the application image is permitted). An application with a restriction level of 3 performs both display restriction and operation restriction of the application image while the vehicle is running when the driver's seat image display device is selected.

  For example, in a navigation application that supports driving of a vehicle, the restriction level is set to “1”. An application such as an image viewer that is displayed on the image display device in the driver's seat and does not hinder concentration on driving is set to a restriction level of “2”. In addition, the limit level is set to “3” for a game application that, when displayed, draws the driver's eyes and hinders concentration on driving.

  FIG. 14 is a flowchart showing operations of application image display restriction and operation restriction of the communication terminal 30 in the information display control apparatus 10 according to the second embodiment. The information display control device 10 mounted on the vehicle repeatedly executes the process of FIG. 14 while the link with the communication terminal 30 is established.

  First, the information display control device 10 checks whether or not the vehicle on which the information display control device 10 is mounted is traveling (step S21). If the vehicle is traveling (YES in step S21), referring to restriction information table 184, it is determined whether the selected image display device is for the driver's seat (whether the attribute is “driver's seat”). Confirm (step S22). If it is an image display device for the driver's seat (YES in step S22), the attribute of the application being executed on the communication terminal 30 is further confirmed, and the restriction level is confirmed (step S23).

  In step S23, when the restriction level of the application being executed on the communication terminal 30 is “1”, both display and operation of the application image are permitted (if display restriction and operation restriction have already been executed, they are released. (Step S24). When the restriction level of the application is “2”, only the application image operation restriction is performed (display of the application image is permitted) (step S25). If the restriction level of the application is “3”, both display restriction and operation restriction of the application image are performed (step S26).

  When the vehicle is stopped (NO in step S21), or when the selected image display device is other than the driver's seat (NO in step S22), application image display restriction and operation restriction are performed. No (step S24).

  With the above processing, display restriction and operation restriction of application images are performed on the driver seat image display device shown in FIG.

  According to the present embodiment, in the information display control device 10 to which a plurality of image display devices are connected, the application image display restriction and operation restriction control methods can be changed for each image display device, which is highly convenient. can get.

  FIG. 11 shows an example in which the installation location in the vehicle as attribute information is subdivided into “driver's seat”, “passenger seat”, “rear seat”, and the like, but as shown in FIG. When the application image display restriction and the operation restriction are performed only by the image display device for use, the attribute information may be “driver's seat” and “other than the driver's seat”.

  Further, in the example shown in FIG. 13, it is defined that application image display restriction and operation restriction are not performed when the vehicle is stopped. However, display restriction or operation restriction is also performed depending on conditions when the vehicle is stopped. May be defined to be performed. Thereby, the control method of the display restriction of the application image and the operation restriction is switched between when the vehicle is running and when it is stopped, which can contribute to further improvement of convenience.

  The application image display restriction and operation restriction in the second embodiment may be executed in combination with the event image in the first embodiment.

<Embodiment 3>
FIG. 15 is a configuration diagram of an information display system according to the third embodiment. The information display system includes a plurality of information display control devices 10. Since the internal configuration of each information display control device 10 shown in FIG. 15 is the same as that of FIG. 1, the illustration is omitted here. Each information display control device 10 is connected to one image display device 21, one audio output device 22, and one operation input device 23.

  To which information display control device 10 the communication terminal 30 is linked (which information display control device 10 communicates with the communication unit 12), and to which communication terminal 30 the information display control device 10 is linked (information display) Which communication terminal 30 the communication unit 12 of the control device 10 communicates with is selected according to the setting by the user. The setting by the user may be performed on either side of the information display control device 10 and the communication terminal 30 to be linked.

  For example, when the user operates the communication terminal 30 and designates the information display control device 10 to be linked, the designated information display control device 10 automatically performs the process of designating the communication terminal 30 as the link subject. Is called. On the contrary, when the user operates the information display control device 10 and designates the communication terminal 30 to be linked, the designated communication terminal 30 automatically designates the information display control device 10 as the link subject. Done. Alternatively, from the viewpoint of privacy protection, a method may be adopted in which both the information display control device 10 and the communication terminal 30 specify a link target.

  In the third embodiment, it is assumed that the plurality of information display control devices 10 are mounted on a vehicle. In addition, in the restriction information table 184, as shown in FIG. 16, the communication terminal 30 (event image permission terminal) that allows the information display control device 10 to display an event image and the information display control device 10 are installed. Attribute information indicating a place (driver's seat, passenger seat, rear seat, etc.) is registered.

  Based on the restriction information table 184, each of the information display control devices 10 performs event image display restriction similar to that of the first embodiment, and application image display restriction and operation restriction similar to those of the second embodiment.

  The event image display restriction is performed by the processing of FIG. FIG. 17 is substantially the same as FIG. 5 except that the content to be confirmed for the communication terminal 30 being linked in step S11 is “event image permission terminal of selected image display device” to “event image of information display control device”. It is changed to "Permitted terminal".

  In other words, the information display control device 10, if the communication terminal 30 being linked is registered in the restriction information table 184 as its own event image permission terminal (YES in step S 11), the information display control device 10 stores the communication terminal 30 in the image display device 21. If the event image is displayed (step S12) and not registered (NO in step S12), the event image is not displayed on the image display device 21, and the display of the application image is maintained (step S13).

  The application image display restriction and operation restriction are performed by the processing of FIG. FIG. 18 is substantially the same as FIG. 14, but the object for confirming the installation location (attribute) in step S <b> 22 is changed from “image display device” to “information display control device”.

  That is, the information display control device 10 is in a state where the vehicle on which it is mounted is traveling (YES in step S21), and if it is for the driver's seat (if its own attribute is “driver's seat”) ( In step S22, YES, the application image display restriction and operation restriction are performed according to the restriction level of the application being executed on the communication terminal 30 (steps S24 to S26). In other cases (NO in step S21 or NO in step S22), display restriction and operation restriction of the application image are not performed (step S24).

  In the present embodiment, it is possible to change the communication terminal 30 that permits the display of an event image for each information display control device 10, or change the display control method for application images and the control method for operation restriction for each information display control device 10. Thereby, the same effect as in the first and second embodiments can be obtained.

  In the present embodiment, the event image display restriction process, the application image display restriction process, and the operation restriction process have been described as being performed by the information display control device 10, but these processes are performed on the communication terminal 30 side. It may be done at.

  That is, when the display restriction of the event image is performed, if the communication terminal 30 refers to the restriction information table 184 of the linked information display control device 10 and the communication terminal 30 is registered as the event image permission terminal, You may make it permit display of an event image with respect to the information display control apparatus 10. FIG.

  When performing application image display restriction and operation restriction, the communication terminal is used to confirm whether the vehicle on which the information display control device 10 is mounted is traveling and whether the information display control device 10 is for a driver's seat. 30 may be performed. Furthermore, if the vehicle is running and the information display control device 10 is for a driver's seat, the communication terminal 30 causes the information display control device 10 to display the application image according to the application restriction level and Operation restriction may be performed.

  In the above description, the communication terminal 30 selects one information display control device 10 to be linked. However, the communication terminal 30 may be capable of linking simultaneously with a plurality of information display control devices 10. In that case, the above-described event image display restriction, application image display restriction, and operation restriction are implemented in each information display control device 10 or communication terminal 30.

<Embodiment 4>
In the third embodiment, the configuration in which the event image permission terminal is registered in the restriction information table 184 of the information display control device 10 has been described. However, in the fourth embodiment, the user ID (owned) of the information display control device 10 is used instead. Is registered. The configuration of the information display system may be the same as that in the third embodiment.

  FIG. 19 shows the restriction information table 184 in the fourth embodiment. The user ID is information that can specify the owner of the information display control device 10, and the same user ID as the user ID of the communication terminal 30 is used. That is, the same user ID is assigned to the information display control device 10 and the communication terminal 30 having the same owner.

  The information display control device 10 according to the fourth embodiment permits the display of the event image only when the owner of the communication terminal 30 being linked is determined to be the same as the owner of the information display control device 10. . Since the information display control device 10 that allows the display of the event image of the communication terminal 30 is limited to that of the owner of the communication terminal 30, the privacy of the owner is protected.

  FIG. 20 is a flowchart showing the display control operation of the information display control apparatus 10 according to the fourth embodiment when an event occurs in the communication terminal.

  The information display control device 10 confirms whether or not the user ID of the linked communication terminal 30 is the same as the user ID registered in the restriction information table 184 (step S31). If both are the same (YES in step S31), the event image of the communication terminal 30 is displayed on the image display device 21 (step S32), and if not the same (NO in step S31), the application is displayed on the image display device 21. The display of the image is maintained (step S33).

  The application image display restriction and operation restriction may be the same as those in the third embodiment, and thus description thereof is omitted.

  Also in the present embodiment, the event image display restriction process may be performed on the communication terminal 30 side. That is, if the communication terminal 30 refers to the restriction information table 184 of the linked information display control apparatus 10 and the user ID registered in the restriction information table 184 is the same as its own user ID, information display control is performed. You may make it permit the display of an event image with respect to the apparatus 10. FIG.

<Embodiment 5>
In the fifth embodiment, in the information display system of the third or fourth embodiment, when the communication terminal 30 is linked to the information display control device 10 for the driver's seat, the screen of the display unit 31 of the communication terminal 30 is displayed in the power saving mode. (For example, a low luminance mode or a non-display mode).

  FIG. 21 is a flowchart showing the operation of the information display control apparatus 10 according to the fifth embodiment. When the link with the communication terminal 30 is established, the information display control device 10 refers to the restriction information table 184 and confirms whether or not it is for the driver's seat (step S41). If the information display control device 10 is for the driver's seat (YES in step S41), the image of the communication terminal 30 is shifted to the power saving mode (step S42). If the information display control device 10 is not for the driver's seat (NO in step S41), nothing is done (the image of the communication terminal 30 continues the operation mode so far).

  Usually, since the driver looks at the screen of the image display device 21 of the information display control device 10 linked to the screen without viewing the screen of the communication terminal 30, even if the screen of the communication terminal 30 is shifted to the power saving mode, Convenience is not impaired. Rather, since the power consumption of the communication terminal 30 can be suppressed, the continuous usable time of the communication terminal 30 becomes longer, and an improvement in convenience can be expected.

  21 may be performed on the communication terminal 30 side. That is, if the communication terminal 30 refers to the restriction information table 184 of the linked information display control device 10 and the information display control device 10 is for a driver's seat, the screen of its own display unit 31 is displayed in the power saving mode. You may make it transfer to.

  It should be noted that the present invention can be freely combined with each other within the scope of the invention, and each embodiment can be appropriately modified or omitted.

  Although the present invention has been described in detail, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
