  The vehicle display device A is configured by the above-described units. Next, the effect animation function in the vehicle display device A will be described with reference to FIGS. 5 and 6.

  FIG. 5 is a timing chart showing a control method of the display device 100 and the head-up display device 200 in the effect animation function, and FIG. 6 shows a display example of the display device 100 and the head-up display device 200 in the effect animation. Is. The first image display region R1 of the display device 100 and the second image display region R2 of the head-up display device 200 are juxtaposed in the vertical direction as viewed from the driver D. Note that the first and second image display regions R1 and R2 may be juxtaposed in the left-right or oblique direction when viewed from the driver D.

  When the ON signal of the IGN switch 600 from the IGN detection unit 400 is input, the control unit 500 outputs a drive signal to the stepping motor 230 of the head-up display device 200 and starts the origin detection operation G. In this embodiment, the stepping motor 230 directs the reflecting mirror 220 to an angle at which sunlight is not reflected toward the liquid crystal display 210 when the IGN switch 600 is turned off, that is, when the power is turned off. An angle that is rotated to an angular position (hereinafter also referred to as a power-off position) and directs the reflecting mirror 220 from the power-off position to the reference angle at which the display light L2 can be reflected toward the eye box of the driver D as an origin detection operation G It is rotationally driven so as to return to the original position which is the position. Note that the rotation drive when the power is off may not be performed.

  The control unit 500 causes the projector 110 of the display device 100 to start the first effect animation at the same time when the stepping motor 230 of the head-up display device 200 starts the origin detection operation G. The first effect animation may be started before the stepping motor 230 performs the origin detection operation G. The first effect animation includes at least one or more events including drawing of predetermined characters and marks, and includes first and third events E1 and E3 described later in the present embodiment. In the present embodiment, the time when the drawing of characters or the like in the first event is started is “start of the production animation”, and the time when characters drawn in the last event are erased is “end of the production animation”. To do. In the first effect animation, the projector 110 first starts drawing the first event E1 (start of the first effect animation). In the first event E1, the projector 110 draws the symbol mark S1 composed of the characters “NS” so as to be gradually reduced to a predetermined size (FIGS. 6A to 6B), and then the image area R1. The image is erased by instantaneously sliding out in the upward direction, that is, the image region R2 direction of the head-up display device 200 (FIGS. 6B to 6C). When the symbol mark S1 is erased, the first event E1 ends. The symbol mark S1 is a manufacturer's mark.

  Returning to FIG. 5, the control unit 500 performs the head-up display after the stepping motor 230 of the head-up display device 200 has completed the origin detection operation G and after the time T1 has elapsed from the end of the first event E1. The second effect animation is started on the liquid crystal display 210 of the display device 200. The start of the second effect animation may be after the end of the first effect animation. The second effect animation is an effect animation having relevance to the first effect animation, and includes at least one event including drawing of a predetermined character or mark, and will be described later in this embodiment. Including two events E2. The liquid crystal display 210 starts drawing the second event E2 in the second effect animation (start of the second effect animation). In the second event, the liquid crystal display 210 draws the symbol mark S1 made up of the characters “NS” that are drawn as the first event on the projector 110 so as to gradually expand (FIG. 6D). To (e)) and then gradually erased (FIG. 6 (e) to (f)). When the symbol mark S1 is deleted, the second event E2 ends (end of the second effect animation). The symbol mark S1 drawn in the first image display region R1 of the display device 100 is erased from the first image display region R1 toward the second image display region R2, and the head-up display device after a predetermined time T1 has elapsed. By displaying in the second image display area R2 of 200, the novel such as the instantaneous movement of the symbol mark S1 from the first display area R1 to the second image display area R2 juxtaposed across the space can be expressed. can get. Note that the “production animation having relevance to the first production animation” is one that the driver D feels as one unified expression when viewed together with the first production animation. Specifically, it includes an event for drawing the same symbol mark as the symbol mark S1 in the first event E1 drawn earlier in the first effect animation or other related symbol marks. In the present embodiment, the second effect animation is related to the first effect animation by drawing the same symbol mark S1 as the first event E1 in the second event E2. . The “same symbol mark” includes a symbol mark having a size or a color that is different or a symbol mark that has been partially modified to the extent that it can be recognized as the same. The “other symbol mark related to the symbol mark” constitutes one expression together with the previously drawn symbol mark. For example, “Welcome” is used as the previously drawn symbol mark. The symbol mark which constitutes one expression (greeting) such as the character “Today is Your Birthday!” Corresponds to this. In addition, if the symbol mark that is drawn earlier is a mark that represents the manufacturer or vehicle type, the symbol mark that constitutes one expression (brand image) such as characters that represent the brand concept or corporate philosophy of the manufacturer. Applicable.

  Returning to FIG. 5, the projector 110 of the display device 100 receives the third event E3 in the first effect animation after the time T2 (T2> T1) has elapsed since the end of the first event E1. Start drawing. At the third event E3, the projector 110 gradually draws the symbol mark S2 composed of the characters “Your safety, Our delight”, and then gradually erases it (FIG. 6 (e) to (f)). When the symbol mark S2 is deleted, the third event E3 ends (end of the first effect animation). The end of the third event E3 (end of the first effect animation) is simultaneous with the end of the second event E2. It is assumed that the symbol mark S2 is a manufacturer's corporate philosophy. By rendering the same symbol mark S1 or the related symbol mark S2 alternately on the display device 100 and the head-up display device 200, the sense of unity can be further increased. Further, by synchronizing the end of the first and second effect animations, it is possible to further increase the sense of unity of the effects.

  When the first and second effect animations are finished, the control unit 500 causes the projector 110 of the display device 100 and the liquid crystal display 210 of the head-up display device 200 to display the vehicle information that is a normal operation.

  The vehicle display device A and the display method thereof include a display device 100 and a head-up display device 200 as a plurality of display means capable of displaying a predetermined image including at least the vehicle information, and according to an input of a predetermined start signal. The display device 100 and the head-up display device 200 display the first and second effect animations each composed of at least one event so as to be linked to each other. By displaying each event of production animation that has been performed individually in the past, it is possible to realize production expression with a sense of unity using a plurality of image display areas R1, R2, and innovative production expression. It is possible to improve the merchantability and design.

  Further, in the vehicle display device A and the display method thereof, the display device 100 is configured so that the first stepping motor 230 of the head-up display device 200 performs the first detection operation G before or during the origin detection operation G. The effect animation is started, and the head-up display device 200 is related to the first effect animation after the origin detection operation G is finished and during or after the execution of the first effect animation. This will start the production animation. The first effect animation that is displayed first on the head-up display device 200 that causes the display device 100 with the earlier displayable time to start the first effect animation first and then has the displayable time later by the origin detection operation G; By starting the relevant second production animation, a unified production expression using a plurality of image display areas R1, R2 is realized, and a difference in displayable time is produced with a unified production expression. It is possible to improve the merchantability and design.

  Further, the first effect animation includes at least a first event E1 for drawing a predetermined symbol mark S1, and the second effect animation includes a symbol mark after a lapse of a predetermined time T1 after the first event E1 ends. It includes at least a second event for drawing S1 or another symbol mark related to the symbol mark S1. As a result, the first effect animation and the second effect animation can be related by drawing the same or related symbol marks in chronological order, and the driver feels uncomfortable with the effect. This makes it possible to improve the merchantability and design.

  In addition, the first image display region R1 of the display device 100 and the second image display region R2 of the head-up display device 200 are juxtaposed in the vertical, horizontal, or diagonal directions as viewed from the driver D. As a result, the driver D can fully recognize the unified performance operation by simultaneously viewing the first and second image display areas R1 and R2 that perform the first and second production animations linked to each other. It is possible to improve merchantability and design.

  It should be noted that the present invention is not limited to this embodiment, and it goes without saying that various modifications are possible within the technical scope thereof. For example, the display means includes the rear projection type display device 100 and the head-up display. The display device is not limited to the device 200, and a direct-view display device such as a liquid crystal display device or an organic EL display device is also applicable. Three or more display means may be provided. Further, the second display means including the driving member that performs the origin detection operation after inputting the start signal is not limited to the head-up display device 200, and includes a driving member that slides the display up and down.
