  The graphic controller 55 performs a drawing process according to the control data from the meter controller 51. The graphic controller 55 causes the instrument display 20 to display a required image by outputting image data to the instrument display 20 through a drawing process.

  FIG. 3 is an explanatory diagram showing a display state of the instrument display 20. In the instrument display 20, the time information held by the vehicle is displayed in the time area 20a, the outside air temperature information around the vehicle is displayed in the outside air temperature area 20b, and the shift POS. Shift position information is displayed in the area 20c. In addition, section travel distance information is displayed in the TRIP area 20d, and total travel distance information is displayed in the ODO area 20e. Further, various types of warning information are displayed in the icon area 20f by icons indicating the display menu, and other vehicle information contents are displayed in the vehicle information content area 20g. For example, in the vehicle information content area 20g, instantaneous fuel consumption, average fuel consumption, boost pressure, and the like are graphically displayed together with a predetermined scale. The vehicle information to be displayed on the instrument display 20 is determined by the manufacturer's initial setting or by an arbitrary setting by the vehicle occupant.

  The graphic controller 55 is connected to a communication interface 56 that connects the portable terminal 100 to the vehicular instrument device 1 in a communicable manner. The communication interface 56 is a wired communication interface, for example, and USB (Universal Serial Bus) is used, for example. Of course, a wireless communication interface can also be used as the communication interface 56, and short-range wireless communication such as Bluetooth (registered trademark) or wireless LAN is also applicable.

  Here, the mobile terminal 100 is a smartphone as an example, but other mobile terminals such as a mobile phone and a PDA (Personal Digital Assistance) can be used. The mobile terminal 100 includes a mobile display unit 101 that displays an image corresponding to the content processed by the mobile terminal 100. After the portable terminal 100 is connected to the communication interface 56 of the vehicular instrument device 1, when a predetermined menu item is selected by the operation unit 70, portable image data is input from the portable terminal 100 to the graphic controller 55. .

  Here, the portable image data is image data indicating a display image displayed on the portable display unit 101, and is output from the portable terminal 100 in response to a request from the graphic controller 55. This portable image data is generated through a predetermined process by the portable terminal 100, and the display image (hereinafter referred to as “portable display image”) displayed on the portable display unit 101 is converted into the resolution of the instrument display 20 and the portable display image area 20h. The image processing is performed so as to correspond to the screen size.

  When portable image data is input from the portable terminal 100, the graphic controller 55 performs a drawing process according to this data. The graphic controller 55 outputs required image data to the instrument display 20 through a drawing process, thereby displaying a portable display image on the instrument display 20.

  FIG. 4 is an explanatory diagram showing another display state of the instrument display 20. The instrument display 20 displays not only vehicle information but also a portable display image. In the instrument display 20, a mobile display image area 20h is set instead of the vehicle information content area 20g shown in FIG. 3, and the mobile display image is displayed in the mobile display image area 20h. Thus, the instrument display 20 simultaneously displays the vehicle information display area for displaying vehicle information (including the display areas 20a to 20f) and the mobile display image area 20h for displaying mobile display images. In addition, the mobile display image area 20h is set separately from the vehicle information display area, and the two are separated.

  The instrument display 20 displays a cursor 20i that moves on the display screen in response to an operation instruction input from the operation unit 70, which will be described later, in accordance with the display of the mobile display image.

  Note that the mobile display image area 20h does not need to be set to the same size and layout as the vehicle information content area 20g, and can have any size and layout. However, the mobile display image area 20 h is preferably set to a size larger than the screen size of the mobile display unit 101 of the mobile terminal 100. Thereby, the vehicle occupant can visually recognize the mobile display image in the vehicle information content area 20g having a screen size larger than that of the mobile display unit 101 of the mobile terminal 100. Further, since the mobile display image area 20h corresponds to a large size, it is possible to display all of the mobile display images displayed on the mobile display unit 101 without cutting them out.

  FIG. 5 is an explanatory diagram for explaining a drawing process by the graphic controller 55. The images displayed on the instrument display 20 are hierarchized. That is, the graphic controller 55 draws an image on each layer (layer) based on the control data output from the meter controller 51 and the portable image data output from the mobile terminal 100, and superimposes one or more layers. Image data is created, and this image data is output to the instrument display 20.

  In the present embodiment, the layer is composed of four layers, and an image formed by superposing four layers L1 to L4 from the upper layer to the lower layer is displayed in the mobile display image area 20h. The cursor 20i is drawn in the uppermost layer L1, the vehicle information is drawn in the second upper layer L2, the portable display image is drawn in the third upper layer L3, and the lower layer L2 Other information (for example, a captured image when a camera is connected) is drawn on the layer L4. As described above, the graphic controller 55 provides the dedicated layer L3 for drawing the mobile display image, and draws the vehicle information on the layer L2 different from the layer L3. In the present embodiment, the cursor 20i is drawn on a layer L1 different from the layer L3 on which the mobile display image is drawn.

  As shown in FIG. 4, the screen displayed on the instrument display 20 is a portion where an image in the upper layer is displayed in a portion where the image is in the upper layer, and there is no image in the upper layer. Then, the image of the lower layer is displayed. That is, the image drawn on the upper layer is preferentially displayed. In addition to the display method in which the lower layer image is not displayed by the upper layer image, a display mode in which the transmittance is set and the lower layer image is transmitted may be adopted. Good.

  The number of layers depends on the specifications of the graphic controller 55 and is not limited to four layers. In relation to the present embodiment, the graphic controller 55 only needs to have at least two layers, and can draw vehicle information on the first layer and draw a portable display image on the second layer. That's fine. The graphic controller 55 controls the display of the instrument display 20 based on an image obtained by superimposing the layer (first layer) on which the vehicle information is drawn and the layer (second layer) on which the mobile display image is drawn. I do. In this case, the cursor 20i is drawn on a layer (first layer) for drawing vehicle information, and thereby the cursor 20i is placed on a layer different from the layer (second layer) on which the mobile display image is drawn. draw.

  Further, as one of the features of this embodiment, the graphic controller 55 limits the drawing range (movement range) of the cursor 20i within the drawing area of the portable display image, that is, within the portable display image area 20h. The cursor 20i is displayed only in the mobile display image area 20h, and its control specifications are set so that the cursor 20i is not displayed beyond this range.

  For example, it is assumed that an operation instruction for continuously moving the cursor 20i in a certain direction (for example, the left direction) is input. In this case, the cursor 20i moves in response to the operation instruction in the mobile display image area 20h. On the other hand, when the outer edge (left outer edge) of the cursor 20i reaches the outer edge (left outer edge) of the mobile display image area 20h, the cursor 20i is displayed in the mobile display image area 20h even when an operation instruction is continuously input. It does not move beyond the outer edge of the, and is maintained at that position.

  FIG. 6 is an explanatory diagram schematically showing the configuration of the operation unit 70. An operation unit 70 is connected to the graphic controller 55. The operation unit 70 is for inputting an operation instruction according to the operation of the vehicle occupant, and is a steering switch (STRSW) provided on the steering wheel 2, for example.

  The operation unit 70 includes four direction switches 70a, 70b, 70c, and 70d that are up, down, left, and right, a confirmation switch 70e, a mode switch 70f, and a back switch 70g. Each switch 70a-70g is comprised by the vehicle passenger | crew so that pressing operation is possible.

  The four direction switches 70a, 70b, 70c, and 70d input operation instructions regarding the moving direction of the cursor 20i in the portable display image area 20h and the moving direction of the portable display image displayed in the portable display image area 20h. Is for. The confirmation switch 70e is used to input an operation instruction related to a vehicle occupant's intention to confirm. The mode switch 70f is used to input operation instructions relating to switching of various modes, and the back switch 70g returns the transition of the mobile display image displayed in the mobile display image area 20h to the previous state. Operation instructions are input.

  The vehicle occupant can switch the type of vehicle information displayed in the vehicle information content area 20g by operating the operation unit 70 in a state where the mobile terminal 100 is not connected to the communication interface 56. In addition, the vehicle occupant operates the operation unit 70 in a state where the mobile terminal 100 is connected to the communication interface 56 and displays predetermined menu items (for example, “display mobile display screen” menu) displayed on the instrument display 20. The portable display image can be displayed on the instrument display 20 by selecting.

  Similarly, the vehicle occupant can operate the operation unit 70 to execute an application installed in the mobile terminal 100. For example, the vehicle occupant operates the direction switches 70a, 70b, 70c, and 70d while viewing the screen display shown in FIG. 4 to move the cursor 20i in the mobile display image area 20h. Then, the vehicle occupant operates the confirmation switch 70d when the desired application and the cursor 20i are superimposed on the portable display image displayed on the instrument display 20. Thereby, the desired application installed in the portable terminal 100 can be executed.

  As described above, the drawing range of the cursor 20i is limited within the mobile display image area 20h, and thus the movement range of the cursor 20i is also limited within the mobile display image area 20h. In the cursor operation through the operation unit 70, the operation position is recognized with reference to the position of the cursor 20i in the mobile display image area 20h, particularly the center position thereof. For this reason, as shown in FIG. 7, the operation unit 70 sets a predetermined inner area CA of the mobile display image area 20h as an operable range by the cursor 20i. Here, the inner area CA is an area defined by a distance from the outer edge of the mobile display image area 20h to the center point 20ia from the outer edge of the cursor 20i (the center distance of the cursor 20i).
