  Hereinafter, the present invention will be described according to a preferred embodiment, but the present invention is not limited to the embodiment shown below, and can be appropriately changed without departing from the gist of the present invention.

  FIG. 1 is a block diagram showing a vehicle display device according to an embodiment of the present invention. A vehicle display device 1 shown in FIG. 1 is a so-called graphic meter that is mounted on a vehicle and includes a TFT-LCD (Thin Film Transistor Liquid Crystal Display) as a display 30. The information is provided to the vehicle occupant by the image display.

  The display device 30 is a display means capable of displaying a color image. In the present embodiment, the display device 30 is a speed meter that indicates the engine speed, a speed meter that indicates the running speed of the vehicle, a water temperature meter that indicates the temperature of the cooling water, and An instrument such as a fuel gauge indicating the remaining amount of fuel is displayed as an image.

  The vehicle display device 1 includes a main CPU (Central Processing Unit) 10, a sub CPU 20 (display control means), and a plurality of ROMs 41 and 42 in addition to the display 30.

  The main CPU 10 receives various vehicle state signals by CAN communication using CAN (Controller Area Network) as a communication protocol. The vehicle state signal is a signal (for example, a vehicle speed pulse) for calculating a state quantity to be displayed on the display device 30 such as an engine speed, a vehicle speed, a coolant temperature, and a fuel remaining amount.

  For example, when the main CPU 10 receives a vehicle speed pulse by CAN communication, the main CPU 10 calculates the vehicle speed from the pulse and transmits a signal of the calculated vehicle speed to the sub CPU 20. The same applies to other engine speeds, cooling water temperatures, remaining fuel amounts, and the like.

  The sub CPU 20 transmits an instruction code to the graphic controller 20a in order to perform display based on the signal input from the main CPU 10. The graphic controller 20a performs a drawing process according to this instruction code. As a result, an image is displayed on the display 30.

  More specifically, the sub CPU 20 is connected to a plurality of ROMs 41 and 42. The first ROM 41 stores a program executed by the sub CPU 20, and the graphic controller 20a functions by executing this program. The second ROM 42 stores various image data necessary for the drawing process, and stores image data necessary for display of instruments such as a speedometer, a water temperature gauge, and a fuel gauge.

  The graphic controller 20a executes a drawing process according to an instruction code from the sub CPU 20 by executing a program stored in the first ROM 41, and performs the drawing process based on the image data stored in the second ROM 42. Will be done. Note that the image data stored in the second ROM 42 is read into the sub CPU 20 when the ignition switch is turned on, for example, and the graphic controller 20a thereafter performs drawing processing using the read image data.

  The rotation switch 50 is a switch that can be rotated by a vehicle driver or the like. FIG. 2 is a front view showing details of the rotary switch 50 shown in FIG. As shown in FIG. 2, the rotary switch 50 is a switch that can be operated counterclockwise (A direction) and clockwise (B direction). In the present embodiment, when the rotary switch 50 is operated in the A direction, the main CPU 10 determines that the ECO mode is designated, and outputs a signal to that effect to the sub CPU 20. Thereby, the sub CPU 20 displays an image for the ECO mode via the graphic controller 20a.

  In the present embodiment, when the rotary switch 50 is operated in the B direction, the main CPU 10 determines that the SPORTS mode is designated, and outputs a signal to that effect to the sub CPU 20. As a result, the sub CPU 20 displays an image for the SPORTS mode via the graphic controller 20a.

  In addition, the rotary switch 50 according to the present embodiment can be pressed. In the present embodiment, when the rotary switch 50 is pressed, the main CPU 10 determines that the NORMAL mode is designated, and outputs a signal to that effect to the sub CPU 20. As a result, the sub CPU 20 displays an image for the NORMAL mode via the graphic controller 20a.

  Here, the vehicular display device 1 according to the present embodiment displays the eco degree display meter 60 when the rotation switch 50 is operated in the A direction, that is, when the ECO mode designation operation is performed. FIG. 3 is a diagram illustrating an example of the eco degree display instrument.

  As shown in FIG. 3, the eco degree display meter 60 displays an eco degree image (swirl image) 61 indicating the eco degree during driving of the vehicle. A circular display area 62 is set in the eco degree display meter 60. The eco degree image 61 includes a plurality of cusp-shaped images 61 a that are inclined with respect to the diameter direction of the circular display region 62 and taper from the outer side to the inner side in a circumferential shape with respect to the circular display region 62. It is an image formed by arranging. In each of the cusp images 61a, the front side of the image is inclined in the B direction. That is, the spiral direction is the B direction. The eco degree display meter 60 displays a larger number of cusp images 61a as the eco degree is higher, and displays a smaller number of cusp images 61a as the eco degree is lower. In this way, the eco degree display meter 60 displays the eco degree by changing the display area of the eco degree image 61 in the circular display region 62. The eco degree is calculated from, for example, the engine speed and the vehicle speed.

  Here, the vehicular display device 1 according to the present embodiment performs an initial display process at the initial display of the eco degree display meter 60 to display an animation.

  FIG. 4 is a diagram showing an animation display according to a comparative example. (A) shows a first animation image, (b) shows a second animation image, and (c) shows a third animation image. (D) shows an image when the animation display is completed, and (e) shows an outline of the animation display.

  First, when the rotation switch is rotated in the A direction, the sub CPU 20 displays the images shown in FIGS. 4A, 4B, 4C, and 4D in this order. The initial display process is executed so that it is displayed.

As is clear from FIGS. 4A to 4D, the plurality of pointed images 61a move from the outer side of the circle toward the inner side of the circle while rotating in the B direction. For example, taking the first 22 pointed image 61a ₂₂ as an example, the first 22 pointed image 61a ₂₂ is seen to move gradually toward the B direction and the circle inside (see the arrow in the figure). The same applies to the other cusp images 61a. That is, as shown in FIG. 4E, the plurality of cusp images 61a are moved toward the B direction and the inner side of the circle.

  However, in such a case, although the driver operates the rotary switch 50 in the A direction, the impression that the plurality of cusp images 61a are moving in the B direction at the initial display of the eco degree display instrument 60. And feel uncomfortable due to the discrepancy with the operation direction.

  This uncomfortable feeling is further felt by performing the animation display described above, but is felt even when the animation display is not performed. In other words, since the plurality of cusp images 61a have tips that taper toward the inside of the circle incline in the B direction, even if they are simply displayed without animation display, the plurality of cusp images 61a are B. The user may receive an impression of moving in the direction, and may feel uncomfortable due to the disagreement with the operation direction.

  FIG. 5 is a diagram showing animation display of the vehicle display device 1 according to the present embodiment, in which (a) shows a first animation image, (b) shows a second animation image, and (c). Shows a third animation image, (d) shows an image when the animation display is completed, and (e) shows an outline of the animation display.

  First, when the rotation switch is rotated in the A direction, the sub CPU 20 displays the images shown in FIGS. 5A, 5B, 5C, and 5D in this order. The initial display process is executed so that it is displayed.

As is clear from FIGS. 5A to 5D, the plurality of pointed images 61a move from the outer side of the circle toward the inner side of the circle while rotating in the A direction. For example, taking the first 22 pointed image 61a ₂₂ as an example, the first 22 pointed image 61a ₂₂ it can be seen that moving the people divided toward the direction A and inner circle (see the arrow in the figure). The same applies to the other cusp images 61a. That is, as shown in FIG. 5E, the plurality of cusp images 61a are moved in the direction A and toward the inner side of the circle.

In addition, the plurality of cusp images 61a are sequentially displayed from the start point S to the end point E in the A direction. Here, in the first embodiment, since the arc is drawn by the plurality of cusp images 61a, the start point S is the side on which the 22nd cusp image 61a ₂₂ is displayed, and the end point E is the first cusp image 61a _1. Will be displayed. Further, the plurality of cusp images 61a can be visually recognized only about 1/3 of the whole on the start point S side in the image shown in FIG. 5A, and also on the start point S side in the image shown in FIG. 5B. Only about 3/5 of the whole is visible.

  As described above, since the sub CPU 20 executes the above-described initial display process, an impression as shown in FIG. 5E is given to the vehicle driver. That is, the vehicle driver feels that the plurality of cuspid images 61a are moving in the A direction and toward the inside of the circle, and the front side of the plurality of cuspid images 61a is directed in the B direction. Even if it is, it becomes difficult to give a sense of incongruity.

  Thus, according to the vehicle display device 1 according to the present embodiment, when the rotation switch 50 is operated in the direction opposite to the inclination direction of the cusp image 61a, a plurality of stigma images 61a are rotated. An initial display process is executed in which the image is moved and displayed from the outer side to the inner side while rotating in the direction, and a plurality of cusp images 61a are sequentially displayed from the start point S to the end point E in the rotation operation direction. . For this reason, even if the inclination direction of the cusp image 61a is opposite to the rotation operation direction, a process of moving and displaying from the outer side of the circle to the inner side while rotating in the rotation operation direction of the plurality of cusp images 61a. As a result of the process of sequentially displaying the plurality of cusp images 61a from the start point S to the end point E in the rotation operation direction, it is as if the plurality of cusp images 61a are moving in the tilt direction. It is difficult to receive an uncomfortable impression, and display with an uncomfortable feeling can be prevented.

  Moreover, since it is used for the eco-degree display meter 60 that indicates the eco-degree during driving of the vehicle, it is possible to prevent a display with a sense of discomfort from a new meter that expresses the eco-state by the cusp image 61a.

  Next, a second embodiment of the present invention will be described. The vehicle display device 1 according to the second embodiment is the same as that of the first embodiment, but the contents of the initial display process are partially different. Hereinafter, differences from the first embodiment will be described.

  6A and 6B are diagrams illustrating animation display of the vehicle display device 1 according to the second embodiment, in which FIG. 6A illustrates a first animation image, FIG. 6B illustrates a second animation image, and FIG. ) Shows a third animation image, (d) shows an image when the animation display is completed, and (e) shows an outline of the animation display.

  First, when the rotation switch is rotated in the A direction, the sub CPU 20 displays the images shown in FIGS. 6A, 6B, 6C, and 6D in this order. The initial display process is executed so that it is displayed.

  As is clear from FIGS. 6A to 6D, each of the plurality of pointed images 61a is gradually displayed from the inner side of the circle toward the outer side of the circle. That is, as shown in FIG. 6E, the plurality of cusp images 61a gradually appear in the A direction.

  In this way, since the sub CPU 20 executes the initial display process, the vehicle driver is given an impression as shown in FIG. That is, the vehicle driver feels that the plurality of cusp images 61a are moving in the A direction, even if the front side of the plurality of cusp images 61a is directed in the B direction. However, it becomes difficult to give a sense of incongruity.

  Thus, according to the vehicle display device 1 according to the second embodiment, when the rotary switch 50 is operated in a direction opposite to the inclination direction of the cusp image 61a, each of the plurality of cusp images 61a is circular. An initial display process of gradually displaying from the inside toward the outside of the circle is executed. For this reason, even if the inclination direction of the cusp image 61a is opposite to the rotation operation direction, the individual cusp images 61a are gradually displayed in the same direction as the rotation operation direction. Thereby, it becomes difficult to receive an impression as if the plurality of cusp images 61a are moving in the tilt direction, and display with an uncomfortable feeling can be prevented.

  Further, as in the first embodiment, since it is used for the eco degree display meter 60 that indicates the eco degree during driving of the vehicle, a display with a sense of incongruity is displayed for a new meter that expresses the eco state by the cusp image 61a. Can be prevented.

  As described above, the present invention has been described based on the embodiment, but the present invention is not limited to the above embodiment, and may be modified without departing from the gist of the present invention.

  For example, the vehicle display device 1 according to the present embodiment is not limited to the eco degree display meter 60, and the above embodiment may be applied to other image displays such as a navigation.

  In the first embodiment, the plurality of cusp images 61a are sequentially displayed from the start point S to the end point E in the A direction. Here, in the first embodiment, since the arc is drawn by the plurality of cusp images 61a, it is clear that the A-direction root side of the arc is the start point S and the A-direction tip side of the arc is the end point E. When a circle is drawn with a plurality of cusp images 61a, since there is no root or tip of the arc, the start point S and the end point E can be set at arbitrary positions.
