Send via.

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

Then, the information terminal side starts the corresponding application based on the start request, and transmits the start information of the started application to the in-vehicle device 10 via the connection unit 340. The in-vehicle device 10 receives the activation information via the connection unit 140 (S506). Here, even if the startup information is to send information only that the application has been started together with the identification information, the audio data and video data associated with the execution of the application by starting 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 making a 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 by the information terminal 30 is the application AA,“ ID: AA ”is transmitted to the in-vehicle device 10 as activation information, and the application executed by the information terminal 30 is the application BB. In the case of, "ID: BB" is transmitted to the in-vehicle device 10 as activation information.

Then, the application identification information determination unit 230 collates 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 issues the activation request is the information terminal 30. It is determined whether the startup is normal (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". Judge 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 the application different from the activation request is started on the information terminal side.

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

Next, the re-request unit 240 counts the number of times the activation request is transmitted to the information terminal 30, and determines whether or not the number of activation requests is equal to or greater than the predetermined number (S510). If the number of times is less than the predetermined number, the re-request unit 240 retransmits the start request of the application that has not been started (S512). If the application that was started by mistake is being executed, the re-request unit 240 also sends a request to stop the application that was started by mistake at the same time. Then, the information terminal device 30 starts the application based on the re-requested start request, and repeats the steps S506 and S508.

When the number of re-requests by the re-request unit 240 exceeds a predetermined number by this cycle, the voice output unit 150 and the display unit 160 notify that the desired application could not be started (S514). On the other hand, in S508, when it is determined by the application identification information determination unit 230 that the same application has been normally started, the process is terminated.

FIG. 7 is a sequence diagram of an in-vehicle device and an information terminal according to the first embodiment of the present invention. First, the vehicle-mounted 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 on the in-vehicle device 10 while this connection is being made, the application activation requesting unit 220 outputs identification information such as an ID that can identify the application to the information terminal. The included start request is transmitted via the connection unit 140 (S550). The information terminal 30 receives the activation request transmitted from the vehicle-mounted device 10 from the application activation request receiving unit 420, and analyzes the received activation request. Then, the application specified by the analysis is started by the application start control unit 430 (S552). Then, the application activation information transmission unit 440 generates information about the activated application as activation information and transmits the information to the in-vehicle device 10. The generated startup information also 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 or not the selected application has been normally activated on the information terminal side (S554). Preferably, the determination is made from the unique and unique ID information provided in each application such as 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 application cooperation operation via the connection means 50. As a result, the audio data and video data generated by the application of the information terminal 30 can be output by the in-vehicle device 10.

Further, when 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). Similar to the first activation request, identification information such as ID is also transmitted. Depending on the embodiment, the operation linked with the in-vehicle device 10 may be started based on the application that has been started by mistake. In that case, the re-request unit 240 requests to stop the running application at the same time as the start request. To 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 the application that was started by mistake, the start of the application is stopped based on the request. Then, the start information of the started application is generated by the application start information transmission unit 440 and transmitted.

Then, the processes of S554 to S558 are repeated until it is determined that the application is normally started with the same ID. Depending on the embodiment, the number of times of sending the start request is limited, and if the application is not normally started on the information terminal side even if the start request is sent more than a predetermined number of times, the user is notified to that effect. You may. If 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 application cooperation operation via the connection means 50. ..

According to the first embodiment described above, when an application different from the request is started on the information terminal side, the identification information of the application is compared to detect a malfunction, and the start request is automatically made again. Since it is sent, it is not necessary for the user to manually operate it, and the convenience can be improved. It also makes it possible to prevent different applications from running.

Next, a second embodiment of the present invention will be described. FIG. 8 is a diagram showing a functional configuration of the application activation program 400A of the information terminal 30 according to the second embodiment of the present invention. The application start program 400A sets a priority for executing the application in addition to the configuration of the application start program 400 mounted on the information terminal side according to the first embodiment of the present invention, and causes the application start control unit 440 to perform the application start program 400A. It includes a priority setting unit 430 that activates an application based on the priority.

The priority setting unit 430 may be set by initial setting or user setting. For example, the priority setting unit 430 automatically changes the priority in response to the connection of the information terminal 30 to the in-vehicle device 10. It may also have a function. The priority setting unit 430 can further set the priority for each genre of the application. For example, when a plurality of audio reproduction applications exist, the priority of only the audio reproduction application is set when the activation request of the audio reproduction application is received from the in-vehicle device 10. This makes it possible to automatically launch the application that needs the highest priority.

The activation operation of the application 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 of FIG. In the following description, it is assumed that the user has selected the audio reproduction application on the in-vehicle device 10.

First, the vehicle-mounted device 10 and the information terminal 30 are connected by the connecting means 50. When the user selects an audio playback application linked to the information terminal 30 on the in-vehicle device 10 while this connection is being made, the application activation requesting unit 220 provides an ID or the like that can identify the application to the information terminal. The activation request including the 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 to the activation request, the application activation control unit 440 receives the audio playback application set in the priority setting unit 430. Based on the priority, the audio playback application having the highest priority is started (S602). Then, the application activation information transmission unit 440 generates activation information including the identification information of the activated application, and transmits the activation information to the in-vehicle device 10.

Next, as in S554 of FIG. 7, it is determined whether or not the selected application has been normally started on the information terminal side (S604). When it is determined that the ID of the application, which is the identification information, is the same and the application is normally started, the vehicle-mounted device 10 and the information terminal 30 start the application cooperation operation via the connection means 50. However, if it is determined that the IDs are different, the re-request unit 240 transmits a re-start request including an ID and a start / stop request to the information terminal 30 as in S556 of FIG. 7 (S606). ..

The information terminal 30 changes the priority of the audio reproduction application by the priority setting unit 430 based on the restart request received by the application activation request receiving unit 420 (S608). Specifically, the priority is changed so that the priority of the application requested to be started is the highest. For example, when the priority is determined by the likelihood, the value of the likelihood of the application requested to be started is incremented to raise the priority. Preferably, the setting is changed so that the priority of the corresponding application is the highest at the time of the first restart request, but depending on the embodiment, the priority is gradually incremented each time there is a restart request. It may be raised to the target. Then, the application activation control unit 440 activates the application having the highest priority in the audio playback application (S610), and the application activation information transmission unit 440 generates activation information including the identification information of the activated application, and is mounted on the vehicle. Transmission is performed to the 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 start request is transmitted with a limit on the number of times, and the application is not normally started on the information terminal side even if the start request is sent more than a predetermined number of times, that fact is notified. You may want to notify the user.

Further, the timing for changing the priority by the priority setting unit 430 is preferably performed when the start request of the same application is continuously received within a certain period of time. For example, when the information terminal 30 is made to record information about the application started by the start request at any time, and it is detected from the identification information at the time of receiving the start request that the start request of the same application is continuously received in a short time. , Let's change the priority. Alternatively, when the in-vehicle device 10 is requested to start again, a priority change request for prompting the change of priority is output, and the setting is changed in response to the reception of the priority change request on the information terminal side. You may.

Further, in one embodiment, when it is detected that the activation request received on the information terminal side is the activation request again, the application activation control unit 440 activates the application that has received the activation request again regardless of the priority. You may try to do it.

According to the second embodiment described above, when different applications are started based on the priority set on the information terminal side, the identification information of the applications is compared to detect the malfunction. By automatically sending the start request again, the priority is changed so that the application for which the start request is started is started, so the user does not have to manually operate it and the convenience can be improved. It will be like. It also makes it possible to prevent different applications from running.

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