Description

  The present invention relates to a technique for remotely operating a mobile device with an in-vehicle device.

  As represented by smartphones (multifunctional mobile phones), recent portable devices have various functions, and for example, devices having a navigation function equivalent to that of an in-vehicle navigation device are also known. However, the display screen of such a portable device is usually smaller in size than the display screen of the display device mounted on the vehicle, and it is difficult to visually recognize and operate the vehicle as compared with the in-vehicle device.

  From such a background, a technology has been proposed in which the functions of the mobile device can be used by the in-vehicle device by configuring the in-vehicle device and the mobile device to be communicable and linked. In this technique, an image displayed on the display unit of the mobile device is displayed on the in-vehicle display device, and an operation performed on the in-vehicle device is reflected on the mobile device. That is, by remotely operating the mobile device with the in-vehicle device, the functions of the mobile device can be used with the in-vehicle device.

  By the way, in order to remotely control the portable device with the in-vehicle device, it is preferable that operations that can be performed with the portable device can be performed with the in-vehicle device. Here, the operation buttons (software buttons) displayed on the display screen of the mobile device are also displayed on the display screen of the in-vehicle device, but the hardware buttons (mechanical buttons) of the mobile device are displayed on the mobile device. Since it is not displayed on the screen, it is not displayed on the display screen of the in-vehicle device. Therefore, a technique has been proposed in which hardware buttons of a portable device are displayed as software buttons on the display screen of the in-vehicle device (see Patent Document 1).

  Specifically, in the information display system described in Patent Document 1, operation command data corresponding to the hardware button of the mobile phone is supplied to the in-vehicle device separately from the information displayed on the display screen of the mobile phone. Is done. The information displayed on the display screen of the mobile phone (for example, map data) is displayed on the display screen of the in-vehicle device, and the operation command (alphanumeric key or function key) of the mobile phone is displayed next to the mobile phone. It is displayed as a software button with a layout almost identical to the telephone operation key layout. When the software button displayed on the vehicle-mounted device side is operated by the user, the corresponding operation command is supplied to the mobile phone. In the mobile phone, the supplied operation command is interpreted as its own operation command, and processing corresponding to the operation command is executed.

JP 2003-244343 A

  The hardware buttons of the portable device have different types, numbers, designs, arrangements, and the like depending on the model of the portable device, but the configuration described in Patent Document 1 does not take into account differences in the model of the portable device. If the type, number, design, arrangement, etc. of the hardware buttons displayed on the display screen of the in-vehicle device are significantly different from the hardware buttons of the mobile device, there is a problem that the operability is deteriorated.

  The present invention has been made in view of these problems, and an object thereof is to provide a technique for improving the operability of hardware buttons displayed on a display screen of an in-vehicle device.

The control device of the present invention is a remote operation for remotely operating a mobile device in an in-vehicle device including a communication means for communicating with the mobile device, a display means for displaying an image, and an input means for inputting an operation. The process is executed. And the execution means with which this control apparatus is provided is an image display process which inputs the image displayed on the display part of a portable apparatus via a communication means, and displays it on a display means, The operation input by the input means is a communication means And an operation output process for outputting to the portable device via a remote control process. The execution means includes an input processing means and a display processing means. The input processing means inputs model specifying information for specifying the model of the portable device via the communication means. Then, the display processing unit causes the display unit to display an operation image corresponding to the hardware button of the portable device together with the image displayed on the display unit of the portable device based on the model specifying information.

  According to such a configuration, different operation images can be displayed on the display unit depending on the model of the portable device. Therefore, compared with a configuration in which a common operation image is displayed regardless of the model of the portable device, it is possible to make the operation image easier to operate (improve operability).

  However, when the operation image is displayed on the display unit, it is necessary to reduce the display area for the image displayed on the display unit of the portable device as compared with the case where the operation image is not displayed on the display unit. Therefore, the operation image may not be displayed depending on the degree to which the operation image is required.

For example, the display processing unit, when no portable device touch panel type identified based on the model identification information, to display the operation image on the display unit together with the image displayed on the display unit of the portable device, the model When the portable device of the model specified based on the specific information has a touch panel, the operation image may not be displayed on the display means. That is, in a portable device having a touch panel, software buttons are displayed on an image displayed on the display unit, and therefore, the degree of need for hardware buttons is low compared to a portable device not having a touch panel. For this reason, in the case of a portable device having a touch panel, the display area for an image displayed on the display unit of the portable device can be enlarged by preventing the operation image from being displayed.

Also, For example, the display processing means is displayed in the case the number of hardware buttons included in the portable device models that are specified based on the model identification information is equal to or greater than a predetermined threshold value, the mobile device display unit The operation image is displayed on the display means together with the image, and the operation image is displayed on the display means when the number of hardware buttons of the portable device of the model specified based on the model specifying information is less than the threshold value. It may not be allowed to. In other words, the smaller the number of hardware buttons, the lower the degree of need for hardware buttons. Therefore, when the number of hardware buttons is less than the threshold value, the operation image is not displayed. The display area for an image displayed on the display unit of the portable device can be enlarged.

However, if the operation image is not displayed at all, an inconvenient situation may occur. Therefore, the display processing means, a display mode for displaying an operation image on the display unit, and a display mode that does not display the operation image on the display means, be switched in response to the operation input by the input means Good. According to such a configuration, the operation image can be displayed as necessary.

By the way, the image for operation can be made into the image according to the kind, number, design, arrangement | positioning, etc. of the hardware button which a portable apparatus has, for example. Such operation images may be stored in advance according to a plurality of types of models, but may be as follows , for example. That, the display processing means, the operation image corresponding to the model identified based on the model identification information, obtained from an external device. According to such a configuration, even when an operation image corresponding to the model of the portable device is not stored, it can be acquired from the external device.

On the other hand, there may be a case where the model of the portable device cannot be specified. In such a case, For example, the display processing means, an image for the default operation, together with the image displayed on the display unit of the portable device may be displayed on the display means. In this way, even when the model of the portable device cannot be specified, standard hardware buttons and the like can be displayed as operation images.

Further, the model specifying information may itself represent the model, but is not limited to this, and any information for specifying the model may be used. For example, the display processing means in association with the unique information and the model of the mobile device, based on the unique information of the mobile device acquired as model identification information by the input processing means, to identify the model of the portable device Also good . According to such a configuration, even when the model identification information does not represent the model itself, the model can be identified based on the model identification information.

[2. Overview of processing]
Next, an outline of processing executed in the wireless communication system of the present embodiment will be described. In this wireless communication system, the in-vehicle device 1 performs VNC (Virtual Network Computing) connection with a smartphone 2 possessed by a user who has boarded the vehicle, and executes remote operation processing for remotely operating the smartphone 2 with the in-vehicle device 1. Specifically, the control unit 16 of the in-vehicle device 1 inputs an image signal representing an image displayed on the display unit 23 of the smartphone 2 via the Wi-Fi communication unit 12, and represents the input image signal. An image display process for displaying an image on the touch panel display unit 13 is executed. In addition, the control unit 16 inputs an audio signal representing the sound output from the sound output unit 25 of the smartphone 2 via the BT communication unit 11, and also outputs the sound represented by the input audio signal from the sound output unit 14. The sound output process to be output is executed. Further, the control unit 16 outputs an operation signal representing an operation input by the touch panel display unit 13 to the smartphone 2 via the BT communication unit 11, and an operation represented by the output operation signal is input by the operation unit 24 of the smartphone 2. The operation output process which makes the smart phone 2 perform the process at the time of being performed is performed. By such remote operation processing (image display processing, sound output processing, and operation output processing), the smartphone 2 can be remotely operated by the in-vehicle device 1 while the VNC is connected. It can be used in the device 1.

  In addition, the control unit 16 displays an operation image (an image representing a software button) corresponding to a hardware button (button command) included in the smartphone 2 in an image display process together with an image displayed on the display unit 23 of the smartphone 2. And displayed on the touch panel display unit 13.

  For example, as shown in FIG. 2A, when a VNC connection is made with a smartphone A having a touch panel display screen A1 and one hardware button A2, the display screen A1 of the smartphone A is displayed on the display screen of the in-vehicle device 1. And an operation image representing the hardware button A2 are displayed. In this example, standard function buttons N1 and N2 are added to the operation image. The standard function buttons are buttons associated with functions used regardless of the model of the smartphone 2, for example, a call start / stop button, a hands-free call / independent call switching button, a volume adjustment button, a numeric keypad button , Up / down / left / right buttons, and a menu return button. Thus, in addition to the button command of the smartphone 2, the unique command on the in-vehicle device 1 side may be displayed as a software button.

  In addition, as shown in FIG. 2B, when a VNC connection is made with a smartphone B having a non-touch panel display screen B1 and a number of hardware buttons B2, B3, B4,. An image displayed on the display screen B1 of the smartphone B and an operation image representing the hardware buttons B2, B3, and B4 are displayed. In this example, all hardware buttons of the smartphone B are not displayed in the operation image, but some hardware buttons are displayed.

  In addition, as shown in FIG. 2C, when a VNC connection is made with a smartphone C having a touch panel display screen C1 and three hardware buttons C2, C3, C4, the display screen of the in-vehicle device 1 includes the smartphone C The image displayed on the display screen C1 and the operation image representing the hardware buttons C2, C3, and C4 are displayed.

  Thus, according to the model of the smart phone 2, the operation image corresponding to the hardware button of the smart phone 2 of the model is displayed. Specifically, the user can operate intuitively by displaying an operation image corresponding to the type, number, design, arrangement, and the like of the hardware buttons of the smartphone 2. Then, in the operation output process, the control unit 16 outputs an operation signal representing an operation on the operation image to the smartphone 2 via the BT communication unit 11, and the operation represented by the output operation signal is performed by the operation unit 24 of the smartphone 2. The process when input is executed by the smartphone 2. In addition, a design here is a color, a shape, arrangement | positioning, and an operation method, for example. As an example of the operation method, for example, there are a smartphone of a type that operates a receiving operation with a push button, and a smartphone of a type that operates with a slide button. Therefore, if the operation method can be matched between the in-vehicle device 1 and the smartphone 2, the operability can be further improved.

  The VNC connection is started on the condition that the in-vehicle device 1 is connected to the smartphone 2 registered as a target for remote operation processing (candidate for VNC connection) by BT wireless communication. . That is, the user registers the smartphone 2 used for remote operation in the in-vehicle device 1 in advance. By performing the pairing setting for BT wireless communication at the time of this registration, the smartphone 2 can be in BT wireless communication thereafter (for example, the power supply and BT wireless communication settings are turned on) ), The in-vehicle device 1 and the smartphone 2 are automatically connected for communication by BT wireless communication. When the communication connection is established by the BT wireless communication, a VNC request is transmitted from the smartphone 2 to the in-vehicle device 1 to establish a VNC connection.

[3. Processing procedure]
Next, a specific processing procedure executed by the in-vehicle device 1 will be described. FIG. 3 is a flowchart of connection processing executed by the control unit 16 of the in-vehicle device 1. When the connection process of FIG. 3 is started, the control unit 16 first determines in S101 whether or not a VNC request has been received from the smartphone 2 via the BT communication unit 11 (in other words, monitors whether there is a VNC request) Monitoring) until a VNC request is received. When determining that the VNC request has been received in S101, the control unit 16 proceeds to S102 and starts the VNC connection with the smartphone 2 that is the transmission source of the VNC request.

  Subsequently, in S103, the control unit 16 acquires model specifying information for specifying the model of the smartphone 2 from the smartphone 2 as a target of VNC connection. The model specifying information may be information representing the model itself, or may be information (for example, manufacturer, carrier, serial number, IP address, etc.) that serves as a clue for specifying the model. . For example, if the manufacturer's smartphone 2 has only one model, the model can be specified from the manufacturer. In some cases, a model can be specified by a combination of a manufacturer and a carrier. Further, by storing the unique information (for example, serial number or IP address) of the smartphone 2 and the model in association with each other at the time of registration in the in-vehicle device 1, the model can be specified from the unique information. In addition, the acquisition procedure of model specific information is not specifically limited, For example, it is comprised so that the request | requirement of model specific information may be transmitted via the BT communication part 11 to the request origin smart phone 2 after reception of a VNC request. Alternatively, the smartphone 2 may be configured to transmit the model specifying information together with the VNC request in advance.

  Subsequently, in S104, the control unit 16 determines whether or not the model of the smartphone 2 that is the target of VNC connection can be specified based on the model specifying information. If the control unit 16 determines in S104 that the model has been specified, the control unit 16 proceeds to S105, and determines whether or not an operation image corresponding to the specified model is stored.

  If it is determined in S105 that the operation image corresponding to the model is not stored, the process proceeds to S106, and after obtaining the operation image from the center 3, the process proceeds to S107. Specifically, information representing the model is transmitted to the center 3 via the wide area communication unit 15. The center 3 includes a data holding unit 31 that stores operation images corresponding to a plurality of types of models. When information representing a model is received from the in-vehicle device 1, the center 3 returns an operation image corresponding to the model. On the other hand, if it is determined in S105 that the operation image corresponding to the model is stored, the process proceeds to S107 as it is.

  In S107, the control unit 16 causes the touch panel display unit 13 to display an operation image corresponding to the model of the smartphone 2 that is a target of VNC connection, and then proceeds to S109. On the other hand, if it is determined in S104 described above that the model could not be specified, the process proceeds to S108, and a default operation image (for example, standard buttons arranged) prepared in advance is displayed on the touch panel. After displaying on the display unit 13, the process proceeds to S109.

  In S109, the control unit 16 determines whether or not the model of the smartphone 2 that is the target of VNC connection is a model that includes a touch panel. If it is determined in S109 that the model is equipped with a touch panel, the process proceeds to S110, the operation image is hidden, and the image displayed on the display screen of the smartphone 2 is displayed larger accordingly. . For example, if it is the display screen of FIG. 2 (A) mentioned above, as shown in FIG. 4, the image currently displayed on the display screen A1 of the smart phone A will be displayed in the whole region of the display screen of the vehicle-mounted apparatus 1. FIG. However, a switching button S for switching between display / non-display of the operation image is displayed on a part of the display screen, the operation image is displayed according to the user's operation, and an operation for hiding it again is possible. And On the other hand, if it is determined in S109 that the model does not include a touch panel, the operation image is not hidden. Thereafter, when the VNC connection is terminated, the connection process of FIG. 3 is terminated.

[4. effect]

Therefore, compared to a configuration in which a common operation image is displayed regardless of the model of the smartphone 2, it is possible to easily perform an operation on the operation image (improve operability).

  Further, the in-vehicle device 1 of the present embodiment displays an operation image when the smartphone 2 that is a target of VNC connection does not have a touch panel, and hides the operation image when it has a touch panel (S109, S110). In this manner, in the case of the smartphone 2 that requires a low degree of hardware buttons, the display area for the image displayed on the display unit 23 of the smartphone 2 is prevented by not displaying the operation image. Can be increased. In addition, the switching button S for switching between display / non-display of the operation image is displayed (S110), and the display mode for displaying the operation image and the display mode for not displaying the operation image are operated with respect to the switch button S. Therefore, the operation image can be displayed as necessary.

  Moreover, since the vehicle-mounted apparatus 1 of this embodiment is acquiring the operation image which is not memorize | stored from the center 3 (S105, S106), it is for operation corresponding to the model of the smart phone 2 used as the object of VNC connection. Even when no image is stored, an operation image corresponding to the model can be displayed.

  Moreover, since the vehicle-mounted apparatus 1 of this embodiment displays the default operation image when the model of the smartphone 2 cannot be specified (S104, S108), the smartphone 2 that is the target of VNC connection. Even when the model cannot be specified, a standard hardware button or the like can be displayed as an operation image.

  Moreover, the vehicle-mounted apparatus 1 of this embodiment can associate and memorize | store the specific information and model of the smart phone 2, and can specify a model based on the specific information acquired as model specific information (S103, S104). Thus, even when the model specifying information does not represent the model itself, the model can be specified based on the model specifying information.
