Description

  The present invention relates to an electronic device that can be connected to an external device, and more particularly, to an electronic device that executes an application of a connected external device on the electronic device.

  In recent years, external devices such as multi-function information terminals such as smartphones and portable music players, and electronic devices mounted on vehicles (hereinafter referred to as in-vehicle devices) are connected and linked together. Can be executed by the in-vehicle device. For example, when the external device cooperates with the in-vehicle device by connection, the image data of the icon displayed on the screen of the information terminal is transferred to the in-vehicle device, and the same icon is displayed on the in-vehicle device. The user can start and operate the application of the information terminal by selecting and operating an icon on the interface of the in-vehicle device.

  As a technology related to cooperation between in-vehicle devices and external devices, for example, obtain application information stored in an information terminal, and automatically select one of the multiple applications to start the application selected on the information terminal In some cases, the user does not need to manually select an application (Patent Document 1).

  FIG. 5 is a block diagram showing a functional configuration of an application activation program installed on the information terminal side according to the first embodiment of the present invention. The application activation program 400 includes a connection detection unit 410, an application activation request reception unit 420, an application activation control unit 430, and an application activation information transmission unit 440.

  The connection detection unit 410 detects whether or not it is connected to the in-vehicle device 10 via the connection unit 340. The application activation request receiving unit 420 receives an application activation request transmitted from the in-vehicle device 10 via the connection unit 340. It is also possible to receive various types of information such as application identification information transmitted together with the activation request. The application activation control unit 430 performs control so that the application received by the application activation request reception unit 420 and received from the in-vehicle device 10 is activated. Further, when there is a request to stop the application, the start of the target application is stopped. The application activation information transmitting unit 440 connects various information including various media data generated by executing the application activated by the application activation control unit 430 and identification information of the application being executed to the in-vehicle device 10. To send through.

  Next, the control operation of the application activation program according to the first embodiment of the present invention will be described with reference to the flowchart of FIG. First, an application to be used is selected on the in-vehicle device 10 (S500). In response to the selection of the application, the connection detection unit 210 detects whether the in-vehicle device 10 is in a connection state via the information terminal 30 and the connection unit 140 (S502). When the connection detection unit 210 detects a connection with the information terminal 30, the application activation request unit 220 transmits an activation request to the information terminal 30 so as to activate the selected application (S504). At this time, the identification information of the selected application is transmitted together. Preferably, as shown in FIG. 10, in response to tapping an icon displayed on the screen of the in-vehicle device 10, the activation request for the selected application information is transmitted. In FIG. 10, the applications are displayed by genre classification on the in-vehicle device side, but may be displayed without genre classification.

  Then, the corresponding application is activated based on the activation request on the information terminal side, and the activation information of the application activated via the connection unit 340 is transmitted to the in-vehicle device 10. The in-vehicle device 10 receives the activation information via the connection unit 140 (S506). Here, even if the activation information is transmitted only with identification information indicating that the application has been activated, the application is activated, and audio data and video data associated with the execution of the application are transmitted together with the identification information of the application. It may be a thing. The activation information needs to include identification information for determination by the application identification information determination unit 230. For example, in FIG. 10B, the ID of the application AA selected by the in-vehicle device 10 is “ID”. : AA ”, and when the application executed on the information terminal 30 is the application AA,“ ID: AA ”is transmitted as the activation information to the in-vehicle device 10, and the application executed on the information terminal 30 is the application BB. In this case, “ID: BB” is transmitted to the in-vehicle device 10 as the activation information.

  Then, the application identification information determination unit 230 compares the identification information of the application that issued the activation request with the identification information of the application included in the received activation information, and the application that issued the activation request is the information terminal 30. It is determined whether or not it is normally activated (S508). For example, in FIG. 10B, when the activation request “ID: AA” is output from the in-vehicle device side and the identification information in the activation information received by the activation of the application AA on the information terminal side is “ID: AA”. It is determined that they are the same. On the other hand, when the identification information in the activation information received by the activation of the application BB on the information terminal side is “ID: BB”, it is determined that an application different from the activation request is activated on the information terminal side.

  The timing at which the application identification information determination unit 230 performs the determination is preferably the timing at which the identification information of the application started on the information terminal 30 is transmitted. Depending on the embodiment, the application identification information determination unit 230 executes an application in response to the normal determination that the same application has been started, or the started application is executed for the time being and the information determination unit is executed during execution. The determination by 230 may be performed.

  Next, the number of times the activation request is transmitted to the information terminal 30 by the re-requesting unit 240 is counted, and it is determined whether or not the number of activation requests is a predetermined number or more (S510). If the number is less than the predetermined number, the activation request for the application that has not been activated by the re-request unit 240 is transmitted again (S512). Note that when an application that has been erroneously started is being executed, the re-request unit 240 also transmits a stop request for the application that has been erroneously started. Then, the information terminal device 30 activates the application based on the re-requested activation request, and repeats steps S506 and S508.

  When the number of re-requests by the re-request unit 240 exceeds a predetermined number by this cycle, a notification that the desired application could not be activated is made via the audio output unit 150 or the display unit 160 (S514). On the other hand, if the application identification information determination unit 230 determines in step S508 that the same application has started normally, the process ends.

  FIG. 7 is a sequence diagram of the in-vehicle device and the information terminal according to the first embodiment of the present invention. First, the in-vehicle device 10 and the information terminal 30 are connected by the connecting means 50. When the user selects an application linked to the information terminal 30 in the in-vehicle device 10 with this connection being made, identification information such as an ID that can identify the application to the information terminal by the application activation request unit 220 is provided. The included activation request is transmitted via the connection unit 140 (S550). The information terminal 30 receives the activation request transmitted from the in-vehicle device 10 from the application activation request receiving unit 420 and analyzes the received activation request. Then, the application identified by the analysis is activated by the application activation control unit 430 (S552). And the application starting information transmission part 440 produces | generates the information regarding the started application as starting information, and transmits to the vehicle-mounted apparatus 10. FIG. The generated activation information includes identification information.

  Next, in the in-vehicle device 10, based on the received application activation information, the application identification information determination unit 230 determines whether the selected application has been normally activated on the information terminal side (S554). Preferably, the determination is made from unique unique ID information included in each application such as an ID. Here, when it is determined that the application is normally started with the same ID, the in-vehicle device 10 and the information terminal 30 start the cooperative operation of the application via the connection unit 50. As a result, audio data and video data generated by the application of the information terminal 30 can be output by the in-vehicle device 10.

  If the application identification information determination unit 230 determines that the IDs are different, the re-request unit 240 transmits the activation request to the information terminal 30 again (S556). Identification information such as ID is also transmitted together with the first activation request. In some embodiments, the linkage operation with the in-vehicle device 10 is started based on an application that has been started in error. In this case, the re-request unit 240 requests to stop the application that is being started simultaneously with the start request. Send.

  In the information terminal 30, the application activation control unit 430 activates the corresponding application based on the activation request transmitted again by the application activation request receiving unit 420 (S558). If there is a request to stop an application that has been started accidentally, the application is stopped based on the request. Then, the activation information of the activated application is generated by the application activation information transmitting unit 440 and transmitted.

  Then, the processes in S554 to S558 are repeated until it is determined that the application is normally started with the same ID. Depending on the embodiment, there may be a limit on the number of transmissions of the activation request, and if the application is not normally activated on the information terminal side even if the activation request is transmitted more than a predetermined number of times, the fact is notified to the user. May be. When it is determined by the application identification information determination unit 230 after the re-request that the application has started normally, the in-vehicle device 10 and the information terminal 30 start the cooperative operation of the application via the connection unit 50. .

  According to the first embodiment described above, when an application different from the request is activated on the information terminal side, the malfunction is detected by comparing the identification information of the application, and the activation request is automatically issued again. Since the transmission is made, the user does not need to manually operate, and convenience can be improved. It is also possible to prevent different applications from being executed.

  Next, the second embodiment of the present invention will be described. FIG. 8 is a diagram illustrating a functional configuration of the application activation program 400A of the information terminal 30 according to the second embodiment of the present invention. In addition to the configuration of the application activation program 400 installed on the information terminal side according to the first embodiment of the present invention, the application activation program 400A sets the priority for executing the application, and the application activation control unit 440 A priority order setting unit 430 that activates an application based on the priority order is included.

  The priority order setting unit 430 may be set by initial setting or user setting. For example, the priority order setting unit 430 automatically changes the priority order in response to the connection of the information terminal 30 to the in-vehicle device 10. A function may also be provided. Furthermore, the priority order setting unit 430 can set a priority order for each genre of application. For example, when there are a plurality of audio playback applications, the priority order of only the audio playback application is set when an activation request for the audio playback application from the in-vehicle device 10 is received. As a result, the application that needs to be given the highest priority can be automatically started.

  The application activation operation of the second embodiment according to the present invention will be described with reference to the sequence diagram of the in-vehicle device and the information terminal in FIG. In the following description, it is assumed that the user has selected an audio playback application on the in-vehicle device 10.

  First, the in-vehicle device 10 and the information terminal 30 are connected by the connecting means 50. When the user selects an audio playback application that is linked to the information terminal 30 in the in-vehicle device 10 with this connection being made, the application activation request unit 220 can identify an application ID that can identify the application to the information terminal. An activation request including identification information is transmitted via the connection unit 140 (S600). The information terminal 30 receives the activation request transmitted from the in-vehicle device 10 from the application activation request receiving unit 420, and in response thereto, the application activation control unit 440 receives the audio reproduction application set in the priority order setting unit 430. Based on the priority order, the audio playback application with the highest priority order is activated (S602). Then, the application activation information transmission unit 440 generates activation information including identification information of the activated application and transmits it to the in-vehicle device 10.

  Next, as in S554 of FIG. 7, it is determined whether the selected application has been normally activated on the information terminal side (S604). When it is determined that the ID of the application that is the identification information is the same and the application has started normally, the in-vehicle device 10 and the information terminal 30 start the cooperative operation of the application via the connection unit 50. However, if it is determined that the IDs are different, the re-request unit 240 transmits the activation request again including the ID and the activation stop request to the information terminal 30 as in S556 of FIG. 7 (S606). .

  Based on the activation request received again by the application activation request receiving unit 420, the information terminal 30 changes the priority of the audio playback application by the priority setting unit 430 (S608). Specifically, the priority order is changed so that the priority order of the application requested to start becomes the highest. For example, when the priority is determined by the likelihood, the priority is increased by incrementing the likelihood value of the application requested to be activated. Preferably, the setting is changed so that the priority of the corresponding application becomes the highest at the time of the first restart request. However, in some embodiments, the priority is gradually incremented each time there is a restart request. It may be raised. Then, the application activation control unit 440 activates the application with the highest priority in the audio playback application (S610), and the application activation information transmission unit 440 generates activation information including identification information of the activated application. Send to device 10.

  Then, the processes of S604 to S610 are repeated until it is determined that the application is normally started with the same ID. As in the first embodiment, if the application is not activated normally on the information terminal side even if the activation request is limited to a limited number of transmissions and the activation request is transmitted more than a predetermined number of times, this is indicated. The user may be notified.

  The timing for changing the priority order by the priority order setting unit 430 is preferably set when a request for starting the same application is received continuously for a certain period of time. For example, when the information terminal 30 records information related to the application activated by the activation request at any time, and it is detected from the identification information when the activation request is received that the activation request for the same application is continuously received in a short time , To change the priority. Alternatively, in the in-vehicle device 10, when the activation request is made again, a priority change request for urging the priority change is output, and the setting is changed in response to the reception of the priority change request on the information terminal side. May be.

  In one embodiment, when the activation request received on the information terminal side is detected as the activation request again, the application activation control unit 440 activates the application that has received the activation request again regardless of the priority order. You may make it do.

  According to the second embodiment described above, when a different application is started based on the priority set on the information terminal side, the malfunction is detected by comparing the identification information of the application, By automatically sending the activation request again, the priority order is changed so that the application that requested the activation is activated, so that it is not necessary for the user to manually operate it, and convenience can be improved. It becomes like this. In addition, it is possible to prevent different applications from being executed.

  Although the preferred embodiment of the present invention has been described in detail, the present invention is not limited to the specific embodiment, and various modifications and changes can be made within the scope of the gist of the invention described in the claims. Is possible.
