Description

  The present invention relates to an in-vehicle device, an in-vehicle system, and a display control method, and more particularly to an in-vehicle device, an in-vehicle system, and a display control method that are suitable for displaying a screen based on an application on a terminal device side on the in-vehicle device side.

  Conventionally, various techniques for improving convenience by cooperation with other devices have been introduced into an in-vehicle device (head unit) (for example, see Patent Document 1).

  Recently, the Car Connectivity Consortium, an organization that promotes innovation of telephone-centric in-vehicle connection solutions on a global scale, has established “Mirror Link ( MirrorLink: registered trademark) ”was announced.

  According to this mirror link, an image based on the application on the mobile terminal side can be displayed on the display unit of the in-vehicle device, and the application can be operated by the operation unit (touch panel or the like) of the in-vehicle device.

  In such a mirror link, there are multiple application categories that can be specified from the in-vehicle device side, such as home / startup (initial screen), menu, music, navigation, etc. Basically, only one application is started. I can't.

  In order to achieve full control of the mirror link, a full control entrance (such as operation buttons on the screen) was prepared on the in-vehicle device side, and when this entrance was selected, the home / startup was activated. . In other words, this home / startup has a screen on which all applications on the portable terminal side (applications corresponding to mirror links) can be operated from the in-vehicle device side.

  Here, FIG. 13 shows a transition example of the screen displayed on the vehicle-mounted device 1 and the portable terminal 2 by the mirror link as a conventional example.

  That is, first, in a state where a mirror link is established between the in-vehicle device 1 and the portable terminal 2, when the full control entrance is selected in the in-vehicle device 1, based on the application stored in the portable terminal 2, A home / startup screen is displayed (STEP 131).

  Next, when a menu is designated on the home / startup screen, the menu screen is displayed (STEP 132).

  Next, when the display (location) of the map around the vehicle position as the navigation function is designated on the menu screen, the map is displayed (STEP 133).

  Next, when Acc of the vehicle is turned off (STEP 134) and then Acc is turned on (STEP 135), a home / startup screen is displayed (STEP 136).

  This STEP 136 is because the start of the home / start-up screen is automatically instructed from the vehicle-mounted device 1 to the portable terminal 2 by using Acc OFF and STEP ON in STEP 134 and STEP 135 as triggers.

  Next, on the home / startup screen of STEP 136, the menu is again designated and the menu screen is displayed (STEP 137). When the display of the map is designated again on this menu screen, the menu is displayed immediately before the Acc is turned off in STEP 134 The map is displayed again (STEP 138).

(Display control method)
Next, an example of the first embodiment of the display control method according to the present invention to which the above-described first embodiment of the in-vehicle device 1 and the in-vehicle system 3 is applied will be described with reference to FIG.

  For convenience, it is assumed that a mirror link has already been established between the in-vehicle device 1 and the portable terminal 2 by the in-vehicle device side cooperation unit 11 and the portable terminal side cooperation unit 21 in the initial state of FIG. In the initial state, the application in the cooperation compatible application storage unit 23 is executed by the mobile terminal side cooperation unit 21 under such a mirror link establishment state, and the screen based on this application is mounted on the vehicle. It is assumed that it is displayed on the machine side display unit 12. Furthermore, in an initial state, it is assumed that a screen based on such an application is stored in the form of identification information by the execution application storage processing unit 14.

  From such an initial state, first, in step 31 (ST31) of FIG. 3, the first detector 15 determines whether or not Acc is turned off. If a positive determination result is obtained in step 31 (ST31), the process proceeds to step 32 (ST32). If a negative determination result is obtained, step 31 (ST31) is repeated. . Here, when a positive determination result is obtained, the first display control unit 16 or the second display control unit 17 starts measuring the elapsed time from turning off Acc.

  Next, in step 32 (ST32), the first detector 15 determines whether or not Acc is turned on. If a positive determination result is obtained in step 32 (ST32), the process proceeds to step 33 (ST33). If a negative determination result is obtained, step 32 (ST32) is repeated. . Here, when a positive determination result is obtained, the above-described measurement of the elapsed time from turning off Acc is terminated.

  Next, in step 33 (ST33), is the first display control unit 16 or the second display control unit 17 based on the elapsed time measurement result described above, whether the time from Acc off to on is within a predetermined time? Determine whether or not. If a positive determination result is obtained in step 33 (ST33), the process proceeds to step 34 (ST34), and if a negative determination result is obtained, the process proceeds to step 35 (ST35).

  When the process proceeds to step 34 (ST34), the first display control unit 16 designates the mobile terminal 2 to start the same application as the application stored by the execution application storage processing unit 14. By performing the control, the in-vehicle device side display unit 12 displays the execution application screen immediately before termination.

  On the other hand, when the process proceeds to step 35 (ST35), the second display control unit 17 controls the portable terminal 2 to specify the start of the home / startup screen, so that the home / startup screen is mounted on the vehicle. It is displayed on the machine side display unit 12.

  Note that the following modifications may be applied to the present embodiment.

(First modification)
For example, in addition to the temporal condition that the time from the mirror link end detection to the resumption detection is within a predetermined time as described above, there is a place condition that the point where the end detection is performed is a predetermined point. In consideration of the above, the predetermined condition may be that either one of the time condition and the place condition is satisfied. In this case, the predetermined point may be a store such as a department store, a convenience store, or a gas station. Further, the fact that the end of the mirror link is detected is a predetermined point on the map data by positioning means such as satellite navigation means (GPS, etc.) or autonomous navigation means (gyro sensor, vehicle speed pulse, etc.). You may detect by specifying a present location.

  As an example of the display control method in this modification, as shown in FIG. 4, step 41 (ST41) is executed between step 32 (ST32) and step 33 (ST33) shown in FIG. .

  That is, in step 41 (ST41), the first display control unit 16 or the second display control unit 17 determines whether or not the point where Acc is turned off is a predetermined point. If a positive determination result is obtained in step 41 (ST41), the process proceeds to step 34 (ST34), and if a negative determination result is obtained, the process proceeds to step 33 (ST33).

  According to this modification, when the point where the mirror link ends is a predetermined point, the execution application screen immediately before the end can be displayed, and when the point where the mirror link ends is not a predetermined point (for example, In the case of home), the home / startup screen can be displayed in consideration of time conditions.

(Second modification)
