Description

Information display control device

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.

Generally, 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

In an information display device mounted on a vehicle, when the vehicle is traveling, an event occurs in the linked communication terminal, and the information display device displays an image for notifying the occurrence of the event (image of the incoming call screen) Etc.), the driver may be distracted and the attention to driving may be distracted. Even in the information display device of Patent Document 1, when an event occurs in the communication terminal, information indicating the occurrence of the event is displayed together with the map, and the same problem occurs.

The present invention has been made to solve the above problems, and provides an information display control device capable of preventing the driver's attention from being distracted by an event occurring at a communication terminal. For the purpose.

An information display control device according to the present invention is an information display control device that can be mounted on a vehicle, and acquires a communication unit that communicates with a communication terminal, and event occurrence information in the communication terminal via the communication unit, When an event occurs in the communication terminal, an image processing unit that displays an event image indicating the occurrence of the event on the display device, and a moving speed of the vehicle are acquired, and display of the event image is limited according to the moving speed. And a control unit.

According to the present invention, it is possible to limit the display of an image (event image) for notifying an event that has occurred in a communication terminal according to the moving speed of the vehicle. For example, by limiting the display of the event image while the vehicle is stopped, it is possible to prevent the driver from paying attention to the event image while the vehicle is traveling and distracting attention.

The communication unit 12 has a function of performing communication necessary for the information display control device 10 to link with the communication terminal 30, and transmits various information such as image data, audio data, and control commands to and from the communication terminal 30. Communicate. The communication method between the communication unit 12 and the communication terminal 30 may be wired communication using, for example, a USB (Universal Serial Bus) cable or a LAN (Local Area Network) cable, or may be a wireless LAN or Bluetooth (registered trademark). Wireless communication may be used.

The image processing unit 13 has a function of generating an image signal for causing the image display device 21 to display an image. In particular, in a state where the information display control device 10 is linked to the communication terminal 30, the image processing unit 13 acquires an image (application image) output by an application running on the communication terminal 30 via the communication unit 12. Can be displayed on the image display device 21.

The image storage unit 14 has a function of storing application images (screen shots) acquired from the communication terminal 30 as needed while the information display control device 10 is linked to the communication terminal 30.

When a predetermined event occurs in the communication terminal 30 when the image processing unit 13 displays an image (application image) of an application running on the communication terminal 30 on the image display device 21, the image processing unit 13 An image (event image) indicating the occurrence of an event is acquired from the communication terminal 30 via the communication unit 12 and displayed on the image display device 21. At this time, the image processing unit 13 maintains the display of the application image. However, during the event occurrence, the transmission of the application image from the communication terminal 30 is interrupted, and the application image cannot be acquired from the communication terminal 30. In that case, the image processing unit 13 displays the application image immediately before the occurrence of the event stored in the image storage unit 14 instead of the application image from the communication terminal 30.

The sound processing unit 15 has a function of generating a sound signal for causing the sound output device 22 to output sound. In particular, in a state where the information display control device 10 is linked to the communication terminal 30, the voice processing unit 15 acquires the voice output by the application running on the communication terminal 30 via the communication unit 12, and the voice output device 22 can be output. Furthermore, when a predetermined event occurs in the communication terminal 30, the sound processing unit 15 can also output a sound for notifying the user of the occurrence of the event from the sound output device 22.

The communication terminal information analysis unit 16 performs identification and state determination of the communication terminal 30 based on information (data) acquired from the communication terminal 30 via the communication unit 12. Information acquired by the communication terminal information analysis unit 16 from the communication terminal 30 includes, for example, attribute information of the application being executed on the communication terminal 30 (application type and the like), and attribute information of the communication terminal 30 (model name, function, Phone number, owner name, etc.), occurrence information of each event (incoming phone call, incoming mail, battery exhausted, communication disabled, etc.).

The communication terminal control unit 17 has a function of controlling the communication terminal 30 by transmitting various control commands and data to the communication terminal 30 via the communication unit 12. In a state where the information display control device 10 is linked to the communication terminal 30, the user uses the operation input device 23 to display the operation screen of the communication terminal 30 displayed on the image display device 21 (the application operating on the communication terminal 30. And an operation screen based on an image of an operation screen corresponding to an event that has occurred in the communication terminal 30 can be performed. The user's operation content is transmitted to the communication terminal 30 by the communication terminal control unit 17, and the communication terminal 30 performs an operation corresponding to the operation content. As a result, remote operation of the communication terminal 30 using the operation input device 23 is realized.

The communication terminal 30 is a smartphone or a mobile phone, and links to the information display control device 10 in addition to the communication function with the far-end communication device 42 via the communication network 41 (network in which the communication terminal 30 is located). Communication function. Further, the communication terminal 30 executes an application for the communication terminal 30 to provide a telephone function, an e-mail (e-mail) transmission / reception function, an Internet browsing function (browser function), and a GPS (Global Positioning System) 43. Various functions such as a navigation function for performing route guidance by using it can be exhibited.

Since the configuration of the communication terminal 30 may be the same as that of a general smartphone, for example, detailed description thereof is omitted, but FIG. 1 illustrates a display unit 31, an operation unit 32, and a control unit 33 particularly related to the present invention. Yes.

The display unit 31 displays an image of an application being executed on the communication terminal 30, or displays an event notification screen or an operation screen image when an event occurs. 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.

Next, the operation of the information display system according to Embodiment 1 will be described. In the following description, it is assumed that the information display control device 10, the image display device 21, the audio output device 22, the operation input device 23, and the moving speed detection device 24 are all in-vehicle devices, and the communication terminal 30 is a smartphone. In addition, the image display device 21 and the operation input device 23 are configured as one touch panel (a “touch panel device 212” described later). Similarly, the display unit 31 and the operation unit 32 of the communication terminal 30 are also configured as one touch panel (a “touch panel unit 312” described later).

In the following description, 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.

First, an overview of the cooperation (link) function between the information display control device 10 and the communication terminal 30 will be described. 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, as shown in FIG. 2, a touch panel device 212 (image display device) connected to the information display control device 10 is provided. 21), the same image as the touch panel unit 312 (display unit 31) of the communication terminal 30 is displayed.

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 touch panel device. 212 and the audio output device 22 can be used for output.

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

For example, when the user touches the “navigation” icon displayed on the touch panel device 212 from the state shown in FIG. 2, the navigation terminal 30 uses the navigation terminal 30 for navigation as when the touch panel unit 312 of the communication terminal 30 is operated. The application starts. Then, as shown in FIG. 3, 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 displayed on the touch panel device 212. The 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.

Thus, 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. The information display control device 10 acquires the moving speed of the vehicle on which it is mounted from the moving speed detection device 24, and changes the content displayed on the image display device 21 (touch panel device 212) according to the moving speed. In the first embodiment, the information display control device 10 displays images having different contents on the image display device 21 depending on whether the vehicle is stopped or running.

When the vehicle is stopped, when a predetermined event occurs in the linked communication terminal 30, the information display control device 10 generates the event while continuing to display the application image of the communication terminal 30 on the image display device 21. An image (event image) showing is displayed. That is, the information display control device 10 causes the image display device 21 to display a composite image obtained by combining the application image of the communication terminal 30 and the event image. The event image is not limited to an image intended only for notification of the occurrence of an event, but may be an image that also functions as an event operation screen (user interface).

For example, the information display control device 10 and the communication terminal 30 are linked, and the image display device 21 (touch panel device 212) and the display unit 31 (touch panel unit 312) of the communication terminal 30 communicate with each other as shown in FIG. Assume that the application image (map) of the terminal 30 is displayed.

When the vehicle is stopped and a call incoming event occurs in the communication terminal 30 from the state of FIG. 3, a screen (incoming call notification) is displayed on the touch panel unit 312 of the communication terminal 30 as shown in FIG. Image) is displayed. Here, as an image of the incoming call screen, an image made up of characters representing the name and telephone number of the caller and operation buttons (icons) of “call start” and “hold” is illustrated.

When there is an incoming call to the communication terminal 30, the information display control device 10 acquires an event image (image of the incoming call screen) from the communication terminal 30, and combines the application image and the event image as shown in FIG. It is displayed on the touch panel device 212. However, since the transmission of the application image from the communication terminal 30 is interrupted by the incoming call, the application image (screen shot) stored in the image storage unit 14 immediately before the incoming call is included in the application image included in the composite image. Use. FIG. 4 illustrates an example in which an event image (image of an incoming call screen) is displayed on a part of an application image (map) on the screen of the touch panel device 212.

The user can remotely operate the communication terminal 30 by touching the event image displayed on the touch panel device 212. For example, in the state of FIG. 4, when the user touches the “call start” button of the event image displayed on the touch panel device 212, a hands-free call using the communication terminal 30 can be started.

On the other hand, when the vehicle is traveling, the information display control device 10 restricts the display of the event image on the image display device 21. That is, even if a predetermined event occurs in the linked communication terminal 30, the application image is continuously displayed on the image display device 21 without displaying the event image.

When the vehicle is traveling, for example, when an incoming call event occurs in the communication terminal 30 from the state shown in FIG. 3, the display unit 31 (touch panel unit 312) of the communication terminal 30 displays a telephone call as shown in FIG. An incoming screen image (event image) is displayed, but an application image that does not include the event image is displayed on the image display device 21 (touch panel device 212). Also at this time, since transmission of the application image from the communication terminal 30 is interrupted by the incoming call, the information display control device 10 displays the application image stored in the image storage unit 14 on the touch panel device 212 immediately before the incoming call. Let

Thus, the information display control device 10 restricts the event image from being displayed on the touch panel device 212 while the vehicle is traveling. Thereby, even if an event occurs in the communication terminal 30, the driver can concentrate on driving without being distracted by the screen of the touch panel device 212.

By the way, some events that occur in the communication terminal 30 do not require notification to the user. For example, it is less necessary to notify the user of information that is less urgent, such as reception of application update information. In addition, among incoming call events, it is conceivable that the user wishes to refuse notification of incoming calls from a specific caller or incoming calls without caller ID.

Therefore, in the information display system of the first embodiment, whether or not to limit the display of the event image is also determined based on the content of the event. Specifically, when a specific event that is determined in advance as not requiring notification to the user occurs, the display of the event image is limited even when the vehicle is stopped.

For example, when a specific event that does not require notification to the user (in this case, an incoming call without caller ID notification) occurs from the state of FIG. 3, the information display control device 10 displays the touch panel device 212 as shown in FIG. Displays an application image that does not include an event image (incoming screen image). Also in this case, since the transmission of the application image from the communication terminal 30 is interrupted by the incoming call, the touch panel device 212 displays the application image (map) stored in the image storage unit 14 immediately before the incoming call.

Note that it is preferable that the user can arbitrarily set which event is notified (or which event is not notified).

FIG. 7 is a flowchart showing an image display operation of the information display control apparatus 10 according to the first embodiment during the link with the communication terminal 30.

When the link between the information display control device 10 and the communication terminal 30 is established, the image processing unit 13 of the information display control device 10 can communicate with the communication terminal as shown in FIG. The application image received from 30 (hereinafter “received application image”) is displayed on the image display device 21 (touch panel device 212) (steps S1 and S2).

When an event occurs in the communication terminal 30, the control unit 11 of the information display control device 10 checks whether or not the event is an event to be notified to the user (step S3). If the event is an event to notify the user (YES in step S3), the control unit 11 acquires the moving speed of the vehicle from the moving speed detection device 24 (step S4), and whether or not the vehicle is stopped. Judgment is made (step S5).

When the vehicle is stopped (YES in step S5), as shown in FIG. 4, the image processing unit 13 compares the event image and the application image stored in the image storage unit 14 (hereinafter referred to as “stored application image”). The composite image is displayed on the image display device 21 (touch panel device 212) (step S6).

When the vehicle is running (NO in step S5), the image processing unit 13 displays the stored application image on the image display device 21 (touch panel device 212) without displaying the event image, as shown in FIG. (Step S7).

When the event that occurred in the communication terminal 30 is an event that is not notified to the user (NO in step S3), the image processing unit 13 stores the event image without displaying it as shown in FIG. The application image is displayed on the image display device 21 (touch panel device 212) (step S7).

The above steps S3 to S7 are repeatedly executed until the event of the communication terminal 30 is completed (step S8). Every time step S5 is executed, it is determined whether or not the vehicle is stopped, and an event image is displayed on the image display device 21. Whether or not to display is determined. Therefore, for example, when the vehicle shifts from the stopped state to the traveling state during the occurrence of the event, the event image displayed on the image display device 21 disappears. Conversely, when the vehicle shifts from the running state to the stopped state during the occurrence of the event, the event image appears on the screen of the image display device 21 at that time.

After that, when the event ends (YES in step S8), the process returns to step S1, and the information display control device 10 causes the image display device 21 to display the received application image until the next event occurs.

Thus, the information display control device 10 according to the first embodiment restricts the display of the event image on the image display device 21 while the vehicle is traveling. Even if an event occurs, the event image is not displayed on the image display device 21 and the display of the application image is continued, so that the driver is distracted by the screen of the image display device 21 and the attention is distracted. Can be suppressed.

When the display of the event image is restricted (NO in step S3 or NO in step S5), the information display control device 10 outputs a sound indicating the occurrence of the event from the sound output device 22. May also be restricted. Since the driver is prevented from paying attention to the sound indicating the occurrence of the event, the effect of the present invention that the driver's attention can be prevented from being distracted can be further enhanced.

At this time, nothing is displayed on the second image display device 21b (second touch panel device 212b).

When the vehicle is stopped, if a predetermined event occurs in the linked communication terminal 30, the information display control device 10 continues to display the application image on the first image display device 21a, and the second image display device. An event image is displayed on 21b.

When the vehicle is stopped, for example, when an incoming call event occurs in the communication terminal 30 from the state of FIG. 9, the information display control device 10 displays the event image (incoming call) acquired from the communication terminal 30 as shown in FIG. Screen image) is displayed on the second image display device 21b (second touch panel device 212b). At this time, the information display control device 10 maintains the display of the application image on the first image display device 21a (first touch panel device 212a). However, since the transmission of the application image from the communication terminal 30 is interrupted, The application image (stored application image) stored in the image storage unit 14 immediately before is displayed. By displaying the event image on a screen different from the application image, it is possible to obtain the effect of ensuring the visibility of the application image even when the event occurs.

On the other hand, when the vehicle is traveling, the information display control device 10 restricts the display of the event image. That is, even if a predetermined event occurs in the linked communication terminal 30, the event image is not displayed on the second image display device 21b, and the display of the application image on the first image display device 21a is continued.

When the vehicle is traveling, for example, when an incoming call event occurs in the communication terminal 30 from the state of FIG. 9, the information display control device 10 displays an event image (incoming screen on the incoming call screen) as shown in FIG. Image) is not displayed on the second image display device 21b (second touch panel device 212b). At this time, the information display control device 10 maintains the display of the application image on the first image display device 21a (first touch panel device 212a). However, since the transmission of the application image from the communication terminal 30 is interrupted, The stored application image stored in the image storage unit 14 immediately before is displayed.

Thus, by restricting the display of the event image on the second image display device 21b while the vehicle is traveling, the driver's attention is prevented from being distracted by the occurrence of the event of the communication terminal 30.

Even in the information display system according to the second embodiment, when a specific event that is determined in advance as not requiring notification to the user occurs, the information display control device 10 does not stop even if the vehicle is stopped. The display of event images shall be restricted.

For example, when a specific event that does not require notification to the user (in this case, an incoming call without caller ID notification) occurs from the state of FIG. 9, the information display control device 10 displays the communication terminal 30 as shown in FIG. The event image (the incoming screen image) is not displayed on the second image display device 21b (second touch panel device 212b), and the application image is continuously displayed on the first image display device 21a (first touch panel device 212a). Let Also in this case, since the transmission of the application image from the communication terminal 30 is interrupted by the incoming call, the application image (map) stored in the image storage unit 14 immediately before the incoming call is stored in the first touch panel device 212a. Display.

FIG. 13 is a flowchart showing an image display operation of the information display control apparatus 10 according to the second embodiment during a link with the communication terminal 30.

When the link between the information display control device 10 and the communication terminal 30 is established, the image processing unit 13 of the information display control device 10 can communicate with the communication terminal as shown in FIG. The application image (received application image) received from 30 is displayed on the first image display device 21a (first touch panel device 212a) (steps S1 and S2). At this time, nothing is displayed on the second image display device 21b (second touch panel device 212b).

When an event occurs in the communication terminal 30, the control unit 11 of the information display control device 10 checks whether or not the event is an event to be notified to the user (step S3). If the event is an event to notify the user (YES in step S3), the control unit 11 acquires the moving speed of the vehicle from the moving speed detection device 24 (step S4), and whether or not the vehicle is stopped. Judgment is made (step S5).

When the vehicle is stopped (YES in step S5), the image processing unit 13 uses the application stored in the image storage unit 14 in the first image display device 21a (first touch panel device 212a) as shown in FIG. An image (stored application image) is displayed (step S16a), and an event image is displayed on the second image display device 21b (second touch panel device 212b) (step S16b).

When the vehicle is running (NO in step S5), the image processing unit 13 displays the stored application image on the first image display device 21a (first touch panel device 212a) as shown in FIG. 11 (step S17a). ), The second image display device 21b (second touch panel device 212b) is not displayed (step S17b).

When the event that occurred in the communication terminal 30 is an event that is not notified to the user (NO in step S3), the image processing unit 13 displays the stored application image as the first image display device as shown in FIG. 21a is displayed (step S17a), and the second image display device 21b is not displayed (step S17b).

The above steps S3 to S5, S16a, S16b, S17a, and S17b are repeatedly executed until the event of the communication terminal 30 ends (step S8), and each time step S5 is executed, it is determined whether or not the vehicle is stopped. Whether to display the event image on the second image display device 21b is determined. Therefore, for example, when the vehicle shifts from the stopped state to the traveling state during the occurrence of the event, the event image displayed on the second image display device 21b disappears. Conversely, when the vehicle shifts from the running state to the stopped state during the occurrence of the event, the event image appears on the screen of the second image display device 21b at that time.

After that, when the event ends (YES in step S8), the process returns to step S1, and the information display control device 10 displays the received application image on the first image display device 21a until the next event occurs.

As described above, the information display control device 10 according to the second embodiment restricts the event image from being displayed on the second image display device 21b while the vehicle is traveling. Thereby, when an event occurs, it is possible to prevent the driver from paying attention to the screen of the second image display device 21b and distracting attention. Moreover, the visibility of the application image in the 1st image display apparatus 21a is securable by displaying an event image on the screen different from an application image.

When restricting the display of the event image (NO in step S3 or NO in step S5), outputting the sound indicating the occurrence of the event from the sound output device 22 may be restricted. When the display of the event image is restricted, the second image display device 21b is in a non-display state. Therefore, the second image display device 21b is set in a power saving mode (for example, a power down mode, a sleep mode, a low luminance mode, etc.). ).

In the above description, the first and second image display devices 21a and 21b have been described as individual display devices. However, the first and second image display devices 21a and 21b can be divided into two units using one screen, for example. It may be realized by a split view monitor that displays images in different directions.

Further, the first and second operation input devices 23a and 23b may be realized by a single operation input device. That is, a 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 as necessary. The switching of the operation mode may be performed by a user operation, or may be automatically performed by the control unit 11. As a method of automatically switching the operation mode, for example, the second operation input device is set to an operation mode that normally functions as the first operation input device 23a and the event image is displayed on the second image display device 21b. A method of switching to an operation mode that functions as 23b is conceivable.

FIG. 8 shows an example in which one audio output device 22 is connected to the information display control device 10, but the audio output device 22 also corresponds to each of the first and second image display devices 21a and 21b. One may be provided.

Further, the number of image display devices, sound output devices, and operation input devices connected to the information display control device 10 may be three or more.
