The front view which shows the display image by the display apparatus for vehicles of the embodiment. The front view which shows transition of the analog type instrument image by the same embodiment. The front view which shows transition of the analog type instrument image used as a modification.

  Hereinafter, an embodiment to which the present invention is applied will be described with reference to the accompanying drawings.

In FIG. 1, a vehicle display device according to an embodiment of the present invention mainly includes an image display device 1, an input unit 2, and a control unit 3.

  As shown in FIGS. 2 and 3, the image display device 1 is composed of a flat panel display such as a liquid crystal display (LCD) panel, an EL panel, or a plasma display. In the present embodiment, the image display device 1 can display an analog instrument image, which will be described later, and a graphic display image as other vehicle information different from the analog instrument image.

  The input unit 2 includes vehicle information detection unit that detects a vehicle state and outputs a state signal to the control unit. In this embodiment, the input unit 2 includes, for example, various sensors that detect vehicle information and a vehicle-side ECU.

  The control means 3 is composed of a microcomputer equipped with a CPU, ROM, RAM, an input / output interface and the like. The control means 3 inputs a status signal from the input means 2 and displays the analog instrument image and the graphic display image. Further, the control means 3 determines whether or not a predetermined switching condition is established based on a status signal from the input means 2 or a user's switch operation, and if the switching condition is established, the analog instrument image and It has a function of changing each image size and display layout of the graphic display image.

  Next, the analog instrument image 10a will be described with reference to FIGS.

The analog instrument image 10 a includes an index part 11, a pointer part 12, and a background part 13.

  The indicator portion 11 is an image imitating an indicator portion such as a scale, letters, numbers, etc. of a real dial provided by, for example, screen printing on a plastic plate. The background portion 13 is an image simulating the background color portion (background portion) of the entity dial.

  The pointer portion 12 is also an image that imitates an actual pointer formed by, for example, forming a colored film on a plastic material. The pointer portion 12 rotates according to the change in the vehicle speed and indicates the vehicle speed by indicating the indicator portion 11.

  The graphic display image 10b displays vehicle information other than the analog instrument image 10a, and displays, for example, warning information and navigation information. In the present embodiment, the image is displayed almost at the center of the flat panel display 1 so as to be sandwiched between two analog instrument images 10a (see a in FIG. 2).

  When the control means 3 determines that the switching condition is satisfied, the graphic display image 10b is enlarged and displayed on the left and right. Accordingly, the horizontal width of the analog instrument image 10a displayed on both sides is reduced and displayed as an elliptical analog instrument image 10a (see b and c in FIG. 2).

As the analog image display unit 10a shrinks, the indicator unit 11 changes its shape so that the pointer unit 12 and the indicator unit 11 overlap even if the length of the pointer unit 12 changes (FIG. 2 b and c).

  At this time, as shown in FIGS. 3A to 3D, the length of the pointer portion 12 changes from a long one to a short one and from a short one to a long one as shown in FIGS. To do.

  Further, as the length of the pointer portion 12 changes, the pointer portion 12 becomes thicker so that the lateral width (width in the direction orthogonal to the longitudinal direction) of the pointer portion 12 is inversely proportional to the length of the pointer portion 12. By changing, the pointer portion 12 is thin when the pointer portion 12 is displayed long, and is thick when the pointer portion 12 is displayed short.

  Further, as shown in FIG. 4, the shape of the analog instrument image 10a is not limited to a circle, and for example, a square or the like may be used. In this case, the shape of the pointer portion 12 is a pointer as in the first embodiment. The tip of the portion 12 overlaps with the indicator portion 11, and the lateral width of the pointer portion 12 is changed to be thick so as to be inversely proportional to the length of the pointer portion 12.

As described above, in the present embodiment, the image display device 1 that displays vehicle information and the control unit 3 that controls the display image displayed on the image display device 1 are provided. The image display device 1 includes at least a display image. As an analog instrument image 10a composed of an indicator portion 11 having a scale portion and a pointer portion 12 that points to the indicator portion 11, the control means 3 displays the length of the pointer portion 12 along with its rotational movement. In the vehicular display device that displays a deformed image obtained by deforming the analog instrument image 10a so that the pointer portion 12 and the indicator portion 11 overlap with each other even if the length of the pointer portion 12 changes, the control means No. 3 makes it easy to display the information indicated by the pointer unit 12 by emphasizing the pointer unit 12 by changing the width of the pointer unit 12 so as to be inversely proportional to the length of the pointer unit 12 when displaying a deformed image. Recognition It is possible to become.

  Further, as a modification of the present invention, a method of providing a hollow in the pointer portion 12 or providing the pointer portion 12 from the outer peripheral edge of the analog instrument image 10a toward the center is conceivable. Similar to the first embodiment, the shape of the portion 12 may be changed so that the lateral width of the pointer portion 12 is increased in inverse proportion to the length of the pointer portion 12.
