The image display device 3 in the embodiment displays a new image from the edge of the ring 4 in a slide-in manner when displaying the new image in a surrounding of the ring 4. The following describes an image display method with reference to
When an alarm is emitted, the image display device 3 displays an alarm image 70 from the edge of the ring 4 in a slide-in manner as illustrated in
The shape of the side border 72c matches with the arc shape of the outer circumference of the ring 4. In the embodiment, the radius of the arc shape of the side border 72c is equal to the radius of the arc shape of the outer circumference of the left end portion 41 of the ring 4. The radius of the arc shape of the side border 72c is, thus, also equal to the radius of the arc shape of the border line BL at the left end.
The image display device 3 displays the alarm image 70 in a slide-in manner such that the alarm image 70 overlays the traveling information image 65. The slide-in direction, which is indicated with arrow Y1, is from the outer circumference of the left end portion 41 of the ring 4 to the outside of the ring 4 along a radius direction thereof. In other words, the image display device 3 displays the alarm image 70 in a slide-in manner from the edge of the ring 4 toward the left side LS in the vehicle width direction W.
When performing the interruption display in accordance with operation input, the image display device 3 displays an image in the same slide-in manner as the alarm display. As illustrated in
The shape of the side border 82c matches with the arc shape of the outer circumference of the ring 4. In the embodiment, the radius of the arc shape of the side border 82c is equal to the radius of the arc shape of the outer circumference of the left end portion 41 of the ring 4. The radius of the arc shape of the side border 82c is, thus, also equal to the radius of the arc shape of the border line BL at the left end.
The image display device 3 displays the interruption image 80 in a slide-in manner such that the interruption image 80 overlays the traveling information image 65. The image display device 3 ends the slide-in display when the side border 82c reaches the border line BL at the left end.
The image display device 3 in the embodiment performs animation display in an inverse manner to that at the start of the interruption display when ending the interruption display. For example, when ending the display of the alarm image 70, the image display device 3 slides the alarm image 70 toward the left end portion 41 of the ring 4. In other words, the alarm image 70 is moved in a slide-out manner. The disappearance of the image of the interruption display in an inverse manner to that at the start of the interruption display allows a user to easily recognize the end of the interruption display. For example, the disappearance of the alarm image 70 in a slide-out manner makes it possible to convey, to the user (typically, the driver), that the state of the vehicle is transited from an alarm state to a normal state in a comprehensible way.
The following describes displaying of a new image with a change of a display mode according to operation input with reference to
As illustrated in
Once completing the slide-out movement of the traveling information image 65, the image display device 3 displays the second information image 83 in a slide-in manner. The second information image 83 includes an information content image 84 and a frame image 85. The information content image 84 is an image of characters and graphics that indicate information provided in the display mode after the change. The frame image 85 has the same structure as the frame images 72 and 82. The frame image 85 has an upper border 85a, a lower border 85b, and a side border 85c. The image display device 3 displays the second information image 83 in a slide-in manner from the edge of the ring 4 as illustrated with arrow Y1.
The timing at which the slide-in display of the second information image 83 starts may be after the completion of the slide-out movement of the traveling information image 65, at the same time when the slide-out movement is completed, during the slide-out movement, or at the start of the slide-out movement. When the traveling information image 65 and the second information image 83 overlap with each other in any of the cases described above, the second information image 83 is displayed in the overlapping region.
As illustrated in
The tire information image 86 is displayed in an information area 87 that has been set preliminarily. The tire information image 86 includes a pressure information image 88. The pressure information image 88, which has a rectangular shape, includes characters indicating the air pressure of each tire of the vehicle. The information area 87 in the embodiment is a region having a rectangular shape. The information area 87 is set in the information display region 31c, for example. The tire information image 86 may be displayed by the interruption display in accordance with operation input or in accordance with a change of the display mode. As illustrated in
When an abnormality is present in any of the air pressure values, the image display device 3 displays, in the information area 87, an alarm image 89 in addition to the pressure information image 88. The alarm image 89 is displayed on the lower side of the pressure information image 88. When displaying the alarm image 89, the image display device 3 performs animation display in which the pressure information image 88 is moved toward the upper side of the image as illustrated with arrow Y3 in
The pressure information image 88 is moved in the information area 87 when an alarm is emitted as described above, thereby making a balanced display of the pressure information image 88 and the alarm image 89 possible. For example, when the pressure information image 88 is displayed by being moved to the upper side while the space for displaying the alarm image 89 is maintained in a normal state, the arrangement of the images is unbalanced. As a result, the user may feel uncomfortable. The embodiment can change the position of the pressure information image 88 in accordance with the presence or absence of the alarm display, thereby making a balanced arrangement of the images in the information area 87 possible. The vehicle display device 1 in the embodiment prevents the layout design of the pressure information image 88 in the information area 87, the space of which is limited, from being unnatural, thereby making it possible to convey necessary information correctly to the user (drive) in a comprehensive manner.
As illustrated in
As described above, the vehicle display device 1 in the embodiment includes the image display device 3, and the ring 4 serving as the frame member. The image display device 3 is disposed in front of the vehicle's driver and displays images. The ring 4 is disposed on the driver side of the image display device 3 and surrounds a part of the image display region 31a in the image display device 3. When displaying a new image in the surrounding of the ring 4, the image display device 3 displays the new image from the edge of the ring 4 in a slide-in manner.
The ring 4, which is the frame member (decorative member) different from the image display device 3, easily attracts the user's eye. A new image is displayed from the ring 4 in a slide-in manner, thereby causing the user to easily be aware of the start of displaying the new image. The vehicle display device 1 in the embodiment can, thus, facilitate the user to recognize the new image. As a result, the vehicle display device 1 in the embodiment can convey the vehicle's state to the user (driver) more reliably. The new image is displayed from the edge of the ring 4 in a slide-in manner, thereby providing a visual effect that causes the user to view the display such that the display hidden behind the ring 4 seems to appear as being slid.
The inside region 31b surrounded by the ring 4 may be a main display region in the image display device 3. In the main display region, information having high priority in the image display device 3 is displayed. The information having high priority is at least one of the physical amount corresponding to the output speed of the engine, the vehicle speed, and the shift position, for example. In the main display region, the indicator image 62, which indicates an operation state of the vehicle's drive system, may be displayed. When the inside region 31b serves as the main display region, the driver particularly pays attention to the inside region 31b in the image display region 31a. The slide-in display of a new image from the ring 4 surrounding the inside region 31b allows the driver to easily be aware of the appearance of the new image.
When displaying a new image with a change of the display mode according to operation input, the image display device 3 in the embodiment moves the image already being displayed toward the edge of the ring 4 in a slide-out manner, and displays the new image from the edge of the ring 4 in a slide-in manner. The slide-out movement of the image being displayed allows the user to easily understand that a change operation of the display mode is being performed.
When displaying a new image by the interruption display, the image display device 3 in the embodiment displays the new image from the edge of the ring 4 in a slide-in manner without moving the image already being displayed in a slide-out manner. The no slide-out movement of the image being displayed allows the user to easily understand that an interruption display is being performed.
In the embodiment, the ring 4 has the arc portion having an arc shape. In the ring 4 in the embodiment, at least the left end portion 41 is the arc portion having an arc shape. The image display device 3 displays, as respective new images, the alarm image 70 including the frame image 72, the image 80 including the frame image 82, and the second information image 83 including the frame image 85 from the edge of the left end portion 41 in a slide-in manner. The shape of the head of each of the frame images 72, 82, and 85 in the slide-in direction (arrow Y1) matches with the shape of the left end portion 41. The matching between the shape of the head of each of the frame images 72, 82, and 85 and the shape of the left end portion 41 can enhance a stage effect when respective new images are displayed in a slide-in manner.
In the embodiment, the new image displayed in a slide-in manner is the alarm image 70 serving as an alarm display. The slide-in display of the alarm image 70 allows the user to easily be aware of the alarm display. The vehicle display device 1 in the embodiment can, thus, facilitate the user (driver) to recognize that the vehicle's state proceeds to an alarm state. In the interruption display, the alarm image 70 and other images may be displayed in different slide-in manners. For example, images other than the alarm image 70 may be displayed in a fade-in manner in addition to the slide-in display while the alarm image 70 may be displayed in a slide-in manner without being displayed in a fade-in manner.
A display method of the vehicle display device in the embodiment includes a display step. At the display step, the image display device 3 included in the vehicle display device 1 displays a new image in the surrounding of the ring 4. The display step is illustrated in

For example, the frame image 72 may have the side border 72c but may not have at least one of the upper border 72a and the lower border 72b, the frame image 82 may have the side border 82c but may not have at least one of the upper border 82a and the lower border 82b, and the frame image 85 may have the side border 85c but may not have at least one of the upper border 85a and the lower border 85b.
The images displayed in the information display region 31c in a slide-in manner may have no frame images. For example, the alarm image 70 may not have the frame image 72. The new image displayed in a slide-in manner may be recognized by at least the border with the image having been displayed. For example, the alarm image 70 may be structured such that the border with the traveling information image 65 can be recognized when displayed in a slide-in manner. For example, a background of the alarm content image 71 in the alarm image 70 has a color or a luminance different from that of the traveling information image 65. The color or luminance of the background of the alarm content image 71 may be appropriately determined such that the outer shape of the alarm image 70 can be recognized. The shape of the background of the alarm content image 71 is the shape of the region surrounded by the frame image 72, for example.
The direction of the slide-in display of the new image is not limited to those exemplarily illustrated. The direction of the slide-in display may be the direction toward the right side RS in the vehicle width direction W or the vehicle up-down direction H, for example. When the direction of the slide-in display is the direction toward the right side RS, the new image can be displayed from the edge of the right end portion 42 of the ring 4. When the direction of the slide-in display is vehicle up-down direction H, the new image can be displayed from the upper edge or the lower edge of the ring 4 in a slide-in manner.
The frame member disposed on the driver side of the image display device 3 is not limited to the ring 4 exemplarily illustrated. The frame member, which surrounds the image display region 31a, can be formed in various shapes. The frame member is not limited to have a closed shape, for example.
