JP 2010-239283 A (page 5-11, FIG. 1-4)

  Recently, an interface standard called a terminal mode that enables operation of a mobile device from the screen of an in-vehicle device is in a practical stage. In this terminal mode, by displaying the same content as the display content of the touch panel provided in the mobile device on the screen of the in-vehicle device, various operations on the mobile device can be performed using the touch panel of the in-vehicle device. In this way, the operation details using the touch panel of the portable device can be reproduced when using the touch panel of the in-vehicle device, and the operability is improved by the fact that the operation using the familiar operation screen becomes possible. Is possible. Moreover, there is also an advantage that on the in-vehicle device side, it is not necessary to prepare an operation screen unique to the in-vehicle device for the portable device.

  By the way, if the operation content using the touch panel of the mobile device is the same as the operation content using the touch panel of the in-vehicle device and the operation can be performed using either device, there is a risk of erroneous operation by the mobile device. There was a problem. For example, if the mobile device is installed at a predetermined position such as a holder and the operation is performed only by the in-vehicle device, such an erroneous operation will not occur. However, if the mobile device is put in a pocket of clothes, a seat or a baggage If the driver or the passenger accidentally touches the touch panel of the mobile device, the operation corresponding to the operation icon may occur if the operation icon is placed at the contact location. Will be started.

  Such an erroneous operation can be avoided by using the technique disclosed in Patent Document 1 described above. However, if this method is used, all operations including operations using the touch panel of the mobile device cannot be performed when connected to the vehicle-mounted device, so it is necessary to prevent erroneous operations that occur when the touch panel is touched by mistake. There has been a problem that the operation is restricted as described above. In addition, when the operation details of the touch panel (operation icons, etc.) are displayed as they are when the operation of the mobile device is restricted, the same operation content is displayed for the user (especially a passenger who is not the owner of the mobile device or the vehicle-mounted device) I do not know which of the mobile device and the in-vehicle device should be operated, but I know that the operation is restricted only after actually operating the touch panel of the mobile device. There is a problem that the operability is poor because the touch panel is operated.

  The present invention has been created in view of the above points, and its purpose is to reduce the range for limiting the operation in order to prevent erroneous operation of the touch panel, and to limit the operation on the portable device side. Accordingly, it is an object of the present invention to provide an in-vehicle system that can improve operability.

  In order to solve the above-described problems, an in-vehicle system according to the present invention is configured such that an in-vehicle device and a portable device are connected to each other, an operation screen displayed on the portable device is displayed on the in-vehicle device, and an operation on the portable device is performed on the in-vehicle device side. In the in-vehicle system in which the mobile device is operated, the mobile device indicates the first display processing means for displaying the operation screen on the first display means and a part of the operation screen displayed on the first display means by the user. A first touch panel for detecting the indicated position when the operation is performed, a first input processing means for determining operation instruction content according to the position on the operation screen detected by the first touch panel, Touch panel invalidation processing means for invalidating operation using the first touch panel when the device is connected to the vehicle-mounted device, and no operation using the first touch panel by the touch panel invalidation processing means. When it is in, and a disabling message display processing means for displaying overlapping a message indicating an invalid operation on the operation screen. The in-vehicle device includes a second display processing unit that displays an operation screen of a portable device that does not include an invalid message on the second display unit, and a part of the operation screen displayed on the second display unit is indicated by the user. A second touch panel for detecting the indicated position when indicated, second input processing means for determining operation instruction contents according to the position on the operation screen detected by the second touch panel, Instruction content transmitting means for transmitting the operation instruction content determined by the second input processing means to the portable device.

  When the mobile device and the vehicle-mounted device are connected, the operation using the touch panel of the mobile device becomes invalid, so that an erroneous operation of the touch panel can be prevented. Further, by limiting the range in which the operation is invalidated to the operation using the touch panel, it is possible to reduce the range in which the operation is restricted in order to prevent an erroneous operation. Further, by displaying a message indicating operation invalidity on the portable device at that time, it is possible to improve the operability by making it possible for the user to know that the operation on the portable device side is restricted.

Further, the operation screen displayed on the first display processing means described above includes an operation icon to be operated by the user, and the invalid message processing means is located at a position that does not overlap with the display position of the operation icon. It is desirable to display a message indicating that the operation is invalid. Thereby, it is possible to prevent the visibility of the operation screen from being deteriorated due to the display of the message, and it becomes easy to grasp the operation icon to be operated.

  In addition, the above-described portable device further includes an operation unit that receives a user's operation instruction without using the first touch panel, and the operation using the first touch panel is invalidated by the touch panel invalidation processing unit. Even so, it is desirable that an operation instruction using the operation means is possible. As a result, only erroneous operation of the touch panel in the mobile device can be prevented, and operability can be improved by enabling the operation using other operation means and using each operation of the mobile device and the in-vehicle device together. It becomes.

The portable device described above further includes a lock state detection unit that detects a lock state of the operation, and a lock release unit that releases the lock state when the lock state detection unit detects that the lock state is detected. After the lock state is released by the lock release means, the operation using the first touch panel is invalidated by the touch panel invalidation processing means . Thereby, when the operation of the portable device is locked, the locked state can be released and only the operation of the touch panel can be invalidated.

The portable device described above further includes connection monitoring means for monitoring the presence / absence of a connection with the in- vehicle device, and when the disconnection of the connection is detected by the connection monitoring means, the touch panel invalidation processing means It is desirable that the operation invalidation using the touch panel is canceled, and the first display processing unit terminates the display of the message indicating the operation invalidation. Thereby, when the connection between the portable device and the vehicle-mounted device is released, the operation using the touch panel can be restarted quickly, and the operability can be further improved.

The input processing unit 56 monitors the operation content of the operation unit 55A and the touch panel 55B, and detects the operation content by the user. The display unit 58 is configured by an LCD or the like. The display processing unit 59 displays an operation screen including a plurality of operation icons and a screen created by the control unit 60 on the display unit 58.

  The control unit 60 is for controlling the entire vehicle-mounted device 50 and includes a CPU. By executing a control program stored in a memory (not shown), operations of the connection monitoring unit 62 and other components (not shown) are realized. The connection monitoring unit 62 monitors whether or not the portable device 10 is connected via the communication interface 52. The in-vehicle device 50 is realized as a navigation device, an audio device, a head unit having these functions, or the like. However, the configuration peculiar to these devices is not directly related to the description of the present invention. It is omitted in the configuration shown in FIG.

  The display processing unit 17 described above is the first display processing unit, the touch panel 13B is the first touch panel, the input processing unit 14 is the first input processing unit, the operation unit 13A is the operation unit, and the touch panel invalidation processing unit 12C. Corresponds to the invalid touch panel processing unit, the invalid message display processing unit 12D corresponds to the invalid message display processing unit, the lock state detection unit 12A corresponds to the lock state detection unit, and the lock release unit 12B corresponds to the lock release unit. In addition, the display processing unit 59 described above serves as the second display processing unit, the touch panel 55B serves as the second touch panel, the input processing unit 56 serves as the second input processing unit, and the terminal mode processing unit 54 serves as the instruction content transmission unit. The connection monitoring unit 62 corresponds to the connection monitoring unit.

  The in-vehicle system of the present embodiment has such a configuration, and the operation will be described next. FIG. 4 is a flowchart showing an operation procedure of the in-vehicle device 50. The terminal mode operation is detected by detecting the connection with the mobile device 10, and then the terminal mode operation is terminated by detecting the disconnection. The operating procedure is shown.

  When the in-vehicle device 50 is activated, the connection monitoring unit 62 determines whether or not the portable device 10 is connected via the communication interface unit 52 (step 100). If it is not connected, a negative determination is made, and this determination is repeated. If the mobile device 10 is connected, an affirmative determination is made in the determination of step 100. When the mobile device 10 is connected for the first time, it is necessary to perform pairing with the in-vehicle device 50. In this case, an affirmative determination is made in step 100 after pairing, and the second and subsequent times. The connection with the portable device 10 is automatically established at the time of connection.

  Next, the connection monitoring unit 62 transmits a command to the mobile device 10 (step 102). By sending this command, activation of the application 22 stored in the memory 20 of the mobile device 10 is instructed.

  The terminal mode processing unit 54 performs a terminal mode operation (step 104). Note that the general terminal mode operation is to display a screen having the same content as the display screen of the mobile device 10 on the display unit 58 of the in-vehicle device 50. However, in this embodiment, the screen is changed to a part of the display content. (The presence or absence of an invalid message indicating invalid operation) is added. This change will be described later. In addition, when an operation screen is displayed on the display unit 58 of the in-vehicle device 50 in the operation of the terminal mode, and one of the operation icons included in the operation screen is selected, a predetermined process corresponding to the selected icon ( The execution of the application 21A of the mobile device 10 is performed, but the description of these operations is omitted.

  In parallel with the operation in the terminal mode, the connection monitoring unit 62 determines whether or not the connection is released (step 106). When the connection is released, for example, when the mobile device 10 leaves the in-vehicle device 50 and is out of the communication range, or when the connection release operation is performed in the in-vehicle device 50 or the mobile device 10, A case where the power is cut off is considered. If the connection is continued, a negative determination is made in the determination in step 106, and the operation returns to step 104 to repeat the terminal mode operation. When the connection is released, an affirmative determination is made in the determination of step 106. In this case, the terminal mode processing unit 54 ends the series of terminal mode operations.

  FIG. 5 is a flowchart showing an operation procedure of the mobile device 10. The operation procedure starts the terminal mode operation when connected to the vehicle-mounted device 50, and then detects the disconnection and ends the operation of the terminal mode. It is shown. FIG. 5 shows an operation procedure after a command for instructing activation of the application 22 is transmitted from the in-vehicle device 50 (step 102 in FIG. 4).

  When the application 22 is executed by the control unit 12 of the mobile device 10 in accordance with a command sent from the in-vehicle device 50, the operation by the operation lock state detection unit 12A shown in FIG. First, the operation lock state detection unit 12A detects the operation lock state of the mobile device 10 (step 200). There may be a case where a user enters a locked state in which a user's operation is not accepted automatically by a manual operation by a user or when a predetermined condition is satisfied (for example, when a predetermined time has passed in a no-operation state). It is done. When the mobile device 10 is in such a locked state, an affirmative determination is made in the determination of step 200, and the lock release unit 12B releases the locked state of the mobile device 10 (step 204).

  After the lock state is released or when the lock state is not established, a negative determination is made in the determination of step 202, and then the touch panel invalidation processing unit 12C invalidates the operation using the touch panel 13B (step 206). For example, the touch panel invalidation processing unit 12C sends an instruction to the input processing unit 14 to invalidate only the operation using the touch panel 13B. In the present embodiment, only the touch panel 13B is subject to operation invalidation, and various operations using the operation unit 13A can be performed.

  Further, the invalid message display processing unit 12D determines a display area for an invalid message indicating that the operation using the touch panel 13B is invalid (step 208). For example, in an operation screen including a plurality of operation icons, the invalid message display processing unit 12D determines a position within a predetermined range that does not overlap with the display positions of the plurality of operation icons as a display area for invalid messages.

  FIG. 6 is a diagram illustrating a specific example of the invalid message display area on the operation screen. The operation screen shown in FIG. 6 includes a plurality of operation icons S. When the user points to each of these operation icons S with a finger or the like, the operation icon is selected, and an operation corresponding to the selected operation icon (such as activation of the application 21A) is started. In the present embodiment, an area D where the operation icon S is not displayed is included in the lower part of the operation screen, and the invalid message display processing unit 12D determines this area as the invalid message display area.

  Next, the display processing unit 17 displays an operation screen including an invalid message (step 210). The operation screen itself is created by an operating system (OS) installed in the mobile device 10 and displayed on the display unit 16 through the display processing unit 17. The display processing unit 17 displays the invalid message in a superimposed manner at a predetermined position (display area determined by the invalid message display processing unit 12D) on the operation screen created by the operating system.

  FIG. 7 is a diagram illustrating a display example of an invalid message. In the operation screen illustrated in FIG. 7, an invalid message “touch operation is invalid” is superimposed and displayed in a region D in the operation screen illustrated in FIG. 6.

  Next, the operation screen transfer area setting unit 12E determines an area (display area) to be displayed on the in-vehicle device 50 on the operation screen shown in FIG. 6 (step 212). In the example shown in FIG. 6, an area excluding the area D in the operation screen is set as a display area in the in-vehicle device 50. The terminal mode processing unit 24 performs a terminal mode operation on the operation screen corresponding to the display area. Thereafter, an operation screen corresponding to this display area is displayed on the display unit 58 of the in-vehicle device 50.

  FIG. 8 is a diagram illustrating a display example of the operation screen in the in-vehicle device 50. The display screen shown in FIG. 8 is an example of split display divided into left and right parts. In the left area, a map image around the vehicle position is displayed. In the right area, an operation screen corresponding to an area (display area set by the operation screen transfer area setting unit 12E) excluding the invalid message in the operation screen (FIG. 7) displayed on the mobile device 10 is displayed. Has been. In the in-vehicle device 50, since the operation using the touch panel 55B is not invalidated, the user directly touches each operation icon included in the operation screen displayed in the right area of the screen shown in FIG. 8 with a finger or the like. By selecting, it is possible to give various instructions to the mobile device 10 such as activation of an application.

  Further, the connection monitoring unit 12F determines whether or not the connection between the mobile device 10 and the in-vehicle device 50 has been released (step 214). If the connection is ongoing, a negative determination is made and this determination is repeated. When the connection is released, an affirmative determination is made in the determination in step 214. Next, the display processing unit 17 displays an operation screen that does not include an invalid message (the entire operation screen shown in FIG. 6) (step 216). The touch panel invalidation processing unit 12C cancels the invalidation of the operation using the touch panel 13B (step 218). Thereafter, the user can perform various operations using the touch panel 13B.

  As described above, in the in-vehicle system of the present embodiment, when the mobile device 10 and the in-vehicle device 50 are connected, the operation using the touch panel 13B of the mobile device 10 becomes invalid, and thus an erroneous operation of the touch panel 13B is prevented. be able to.

  Further, by limiting the range in which the operation is invalid to the operation using the touch panel 13B, it is possible to reduce the range in which the operation is limited to prevent an erroneous operation. In particular, only an erroneous operation of the touch panel 13B in the mobile device 10 can be prevented, and the operability can be achieved by using the operations of the mobile device 10 and the vehicle-mounted device 50 together by enabling the operation using the other operation unit 13A. Can be improved.

  Further, by displaying an invalid message indicating invalid operation on the mobile device 10 at that time, it is possible to improve the operability so that the user can know that the operation on the mobile device 10 side is restricted. it can. In particular, by displaying an invalid message at a position that does not overlap the display position of the operation icon, it is possible to prevent the visibility of the operation screen from deteriorating due to the display of the invalid message, and the operation to be operated The icon can be easily grasped.

  In addition, since the operation using the touch panel 13B is invalidated after the lock state is released when the mobile device 10 is in the locked state, this operation is performed even when the entire operation of the mobile device 10 is locked. Only the operation of the touch panel 13B can be invalidated by releasing the lock state.

  Further, the connection state between the mobile device 10 and the in-vehicle device 50 is monitored in the mobile device 10, and the operation using the touch panel 13 </ b> B of the mobile device 10 is performed when the connection between the mobile device 10 and the in-vehicle device 50 is released. It can be restarted quickly, and the operability can be further improved.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, in the above-described embodiment, when an invalid message is displayed over a part of the operation screen (FIG. 7), a part of the operation screen below the predetermined range including the invalid message is displayed. Although hidden, as shown in FIG. 9, only the character string as the invalid message may be superimposed on the operation screen and displayed so as not to overlap the operation icon.

  In the above-described embodiment, the mobile device 10 having the telephone function has been described. However, the present invention can also be applied to a case where a mobile device having no telephone function is used. For example, a case where the present invention is applied to a case where a tablet terminal that is one size larger than a portable terminal device called a smartphone is connected to the in-vehicle device 50 can be considered.

  Moreover, in embodiment mentioned above, when the connection with the portable apparatus 10 is detected in the vehicle equipment 50, a command is transmitted toward the portable apparatus 10, and the application 22 is executed in the portable apparatus 10 that has received the command. Although the operation procedure shown in FIG. 5 is implemented, the mobile device 10 itself may detect the connection with the in-vehicle device 50 and implement the operation procedure shown in FIG.

  As described above, according to the present invention, when the mobile device 10 and the vehicle-mounted device 50 are connected, the operation using the touch panel 13B of the mobile device 10 becomes invalid, and thus an erroneous operation of the touch panel 13B is prevented. Can do.
