Summary of the Invention

Problems to be Solved by the Invention

[0004] In a vehicle display device, when displaying an image with a sense of depth, it is desirable to suppress a decrease in the visibility of the image. For example, when the image is displayed on the back side in the depth direction, the size of the image may become small and the visibility may decrease. For example, when expressing a sense of depth in an image, the interval between a plurality of contents may be compressed and the visibility may decrease.

[0005] An object of the present invention is to provide a vehicle display device that can display an image with a sense of depth while suppressing a decrease in visibility. [[ID=​​​​​The present invention provides a vehicle display device comprising a display device that displays an image to the driver of a vehicle, and a control unit that controls the display device, wherein the image displayed by the display device includes a first image and a second image, the first image being an image that mimics the scenery in front of the vehicle and expresses depth based on a first vanishing point, and the second image being an information-providing image displayed within the same area as the display area of ​​the first image and expressing depth based on a vanishing point different from the first vanishing point. [Effects of the Invention]

[0007] The vehicle display device according to the present invention comprises a display device that displays an image to the driver of a vehicle, and a control unit that controls the display device, wherein the image displayed by the display device includes a first image and a second image.

[0009] A vehicle display device according to an embodiment of the present invention will be described in detail below with reference to the drawings. However, this embodiment does not limit the present invention. Furthermore, the components in the following embodiments include those that are easily conceivable by those skilled in the art or that are substantially identical.

[0010] [Embodiment] Embodiments will be described with reference to FIGS. 1 to 14. This embodiment relates to a vehicle display device. FIG. 1 is a view of a vehicle equipped with the vehicle display device of the embodiment, FIG. 2 is a configuration diagram of the vehicle display device according to the embodiment, FIG. 3 is a view showing a first image and a second image according to the embodiment, FIG. 4 is a view for explaining the size of an image based on a first vanishing point, FIG. 5 is a view showing a scenery in front of the vehicle and a virtual image, FIGS. 6 and 7 are views showing an example of the first image and the second image, FIG. 8 is a view showing a scenery in front of the vehicle and a virtual image, FIGS. 9 to 11 are views showing other examples of the first image and the second image, FIG. 12 is a view showing a content image displayed together with a guidance image, FIG. 13 is a view showing an example of a third vanishing point, and FIG. 14 is a view showing a virtual image displayed in an inclined manner.

[0011] An example of the vehicle display device 1 according to this embodiment is shown in FIGS. 1 and 2. The vehicle display device 1 of this embodiment has a display device 3 that displays an image to the driver 200. The display device 3 may be a meter device, a head-up display device, or other image display devices.

[0012] As will be described below, the illustrated display device 3 displays a virtual image Vi to the driver 200. As shown in FIG. 2, the vehicle display device 1 displays the virtual image Vi to the driver 200 by projecting display light Lt of an image onto a reflection surface 110a in front of the driver 200 in the vehicle 100. The reflection surface 110a of this embodiment is the inner surface of the windshield 110 on the vehicle interior side. The reflection surface 110a may be provided with a coating for reflection.

[0013] As shown in FIG. 2, the vehicle display device 1 has a housing 2, a display device 3, and a control unit 10. The housing 2 is disposed below the windshield 110 of the vehicle 100. The housing 2 is, for example, housed below the dashboard 120. The display device 3 and the control unit 10 are housed in the housing 2.

[0014] The display device 3 includes an image display unit 4, a first mirror 5, and a second mirror 6. The image display unit 4 has, for example, a liquid crystal display device such as a TFT-LCD (Thin Film Transistor-Liquid Crystal Display). The image display unit 4 has a display surface 4a for displaying an image. The display light Lt of the image is emitted from the display surface 4a. The image display unit 4 has, for example, a backlight unit disposed on the back side with respect to the display surface 4a. In this case, the display light Lt is generated by the light of the backlight unit.

[0015] The first mirror 5 reflects the display light Lt output from the image display unit 4 toward the second mirror 6. The first mirror 5 has a reflection surface 5r for reflecting light. The illustrated shape of the reflection surface 5r is a convex aspherical surface. The shape of the reflection surface 5r is a shape that corrects the distortion of the image generated in the second mirror 6 and the windshield 110.

[0016] The second mirror 6 reflects the display light Lt incident from the side of the first mirror 5 toward the windshield 110. The housing 2 has a transparent cover 2a. The cover 2a faces the opening of the dashboard 120. The display light Lt passes through the cover 2a from the side of the second mirror 6 toward the side of the windshield 110. The reflection surface 110a of the windshield 110 reflects the display light Lt toward the eye point EP of the vehicle 100. The driver 200 visually recognizes the virtual image Vi by the display light Lt. The position of the virtual image Vi as seen from the driver 200 is in front of the windshield 110 in the vehicle longitudinal direction X.

[0017] The second mirror 6 of the present embodiment has a concave reflection surface 6r. The shape of the reflection surface 6r is an aspherical curved shape and is a shape that enlarges the image. The virtual image Vi has an image vertical direction Gv when seen from the driver 200.

[0018] The control unit 10 shown in Figure 2 controls the display device 3. More specifically, the control unit 10 commands the image display unit 4 to display an image on the display surface 4a. The control unit 10 may also generate the image to be displayed and output this image to the image display unit 4. The control unit 10 controls the image display unit 4 based on a program stored, for example, in the memory of the display device 3.

[0019] The control unit 10 acquires various information about the vehicle 100 from the vehicle ECU or the like that controls the vehicle 100. The information acquired by the control unit 10 includes, for example, the vehicle 100's driving speed, the vehicle 100's shift position, route guidance information from the navigation system, the vehicle 100's location information, information about the vehicle 100's battery, and information about driving control such as ACC (Adaptive Cruise Control).

[0020] As described below, the image displayed by the display device 3 includes a first image G1 and a second image G2. Figure 3 shows an example of the first image G1 and the second image G2. In this embodiment, both the first image G1 and the second image G2 are displayed in the same display area GR. The shape of the display area GR is, for example, a rectangle.

[0021] The first image G1 is an image that simulates the view in front of vehicle 100. The first image G1 is an image that expresses depth based on the first vanishing point Vp1. The exemplified first vanishing point Vp1 is located above the vertical direction Gv of the image relative to the display area GR. However, the first vanishing point Vp1 may be set inside the display area GR.

[0022] The first image G1 includes, for example, the line image 30 shown in Figure 3. The line image 30 is an image that represents the boundary of the lane on which the vehicle 100 travels. The line image 30 is a linear image that extends toward the first vanishing point Vp1.

[0023] Line image 30 has a left line image 30L and a right line image 30R. The left line image 30L is an image that represents the left boundary of the lane in which the vehicle 100 is traveling. The left line image 30L is displayed to the left of the image in the horizontal direction Gh relative to the vehicle image 20, which is an image representing the vehicle 100. The right line image 30R is an image that represents the right boundary of the lane in the same way. The right line image 30R is displayed to the right of the image in the horizontal direction Gh relative to the vehicle image 20. The distance between the two line images 30L and 30R narrows as you move towards the upper side in the vertical direction Gv of the image.

[0024] The second image G2 is an informational image displayed within the same area GR as the display area GR of the first image G1. The second image G2 is an image that represents depth based on the second vanishing point Vp2. The second vanishing point Vp2 is a different point from the first vanishing point Vp1. The second image G2 includes, for example, an object image 70 which is an image showing a detected forward object.

[0025] The object in front is, for example, a preceding vehicle 400 detected in ACC control. In this case, the position and size of the object image 70 change according to the distance to the preceding vehicle 400. When the distance increases, the object image 70 moves towards the back in the depth direction based on the second vanishing point Vp2, as indicated by arrow AR1. Conversely, when the distance decreases, the object image 70 moves towards the front in the depth direction based on the second vanishing point Vp2, as indicated by arrow AR2.

[0026] The second vanishing point Vp2 is located above the first vanishing point Vp1 in the vertical direction Gv of the image. In the vehicle display device 1 of this embodiment, the size of the object image 70 changes based on the second vanishing point Vp2. This makes it possible to display the object image 70 at an appropriate size. In Figure 4, the object image 70 generated based on the first vanishing point Vp1 is shown by a dashed line. The object image 70 in Figure 4 is smaller than the object image 70 shown in Figure 3. Also, the object image 70 generated based on the first vanishing point Vp1 becomes too small when it moves towards the back of the first vanishing point Vp1.

[0027] In contrast, the object image 70 generated based on the second vanishing point Vp2 can be displayed at an appropriate size in the display area GR. The position of the second vanishing point Vp2 is determined so as to ensure the visibility of the object image 70. In the object image 70 generated based on the second vanishing point Vp2, the change in the size of the object image 70 as it moves along the depth direction is gradual. Therefore, the vehicle display device 1 of this embodiment can display information with a sense of depth while ensuring the visibility of the object image 70.

[0028] Furthermore, the distance between the left line image 30L and the right line image 30R is widened so that the user does not feel any discomfort with the object image 70. As shown in Figure 3, the left line image 30L and the right line image 30R are positioned so as not to intersect with the trajectory L70 of the object image 70. The trajectory L70 is a straight line in the depth direction based on the second vanishing point Vp2, and is the trajectory of the lower end of the object image 70.

[0029] Because the line image 30 does not intersect with the trajectory L70, the user is less likely to feel any discomfort with the display size of the object image 70. Therefore, the vehicle display device 1 of this embodiment can create a natural sense of depth while allowing two images G1 and G2 with different vanishing points to coexist in the same display area GR.

[0030] Figures 5 and 6 show a virtual image Vi as vehicle 100 is catching up to a preceding vehicle 400. As shown in Figure 5, the virtual image Vi is superimposed on the view Sc in front of vehicle 100. As shown in Figure 6, the first image G1 of the virtual image Vi includes a left line image 30L and a right line image 30R. The second image G2 of the virtual image Vi includes a vehicle image 20 and an object image 70. The virtual image Vi further includes a speed image 21, a set value image 22, and multiple graphic images 60.

[0031] Speed ​​image 21 is an image showing the driving speed of vehicle 100, for example, an image of characters indicating the speed. Speed ​​image 21 is always displayed, for example, when vehicle 100 is in driving mode. Object image 70 is an image showing the preceding vehicle 400, an image that mimics the shape of the vehicle. Object image 70 showing the preceding vehicle 400 is displayed, for example, when ACC control is being performed. Object image 70 is, for example, an image of the vehicle viewed from behind.

[0032] As shown in Figure 6, the vehicle image 20 and the object image 70 are drawn in perspective based on the second vanishing point Vp2. During ACC control, a set value image 22 and a graphic image 60 are also displayed. The set value image 22 is the set value of the driving speed in ACC control. In the following description, the set value of the driving speed in ACC control will be simply referred to as the set speed. The set value image 22 is positioned above the speed image 21 in the vertical direction Gv. The set value image 22 is displayed in smaller characters than the speed image 21. The speed image 21 and the set value image 22 may be displayed side by side in the depth direction based on the first vanishing point Vp1, or side by side in the depth direction based on the second vanishing point Vp2.

[0033] Graphic image 60 is an image that three-dimensionally represents changes in the inter-vehicle distance during ACC control. The shape of graphic image 60 in this embodiment is rectangular. Graphic image 60 in Figure 6 has images 61, 62, and 63. The three graphic images 60 are displayed partially overlapping. The relative positions of the three graphic images 60 change according to the target value of the inter-vehicle distance, etc.

[0034] The three graphic images 60 are arranged, for example, along a line leading to the first vanishing point Vp1. The graphic images 60 may also be arranged along a line leading to the second vanishing point Vp2. The graphic images 60 are displayed between the vehicle image 20 and the object image 70. Image 61 is positioned at the closest position among the three graphic images 60. Image 63 is positioned at the furthest position among the three graphic images 60. The three graphic images 60 are arranged at equal intervals along the depth direction based on the vanishing points Vp1 and Vp2.

[0035] Of the multiple graphic images 60, the graphic image 60 displayed closest to the viewer is larger than the other graphic images 60. Of the multiple graphic images 60, the graphic image 60 displayed furthest from the viewer is smaller than the other graphic images 60. Furthermore, when three or more graphic images 60 are displayed, the graphic images 60 become smaller as they move from the foreground towards the vanishing points Vp1 and Vp2.

[0036] In this embodiment, image 61 is displayed such that a portion of image 61 is superimposed on the vehicle image 20. In other words, a portion of image 61 is hidden by the vehicle image 20. This display makes it easy for the driver 200 to understand that the multiple graphic images 60 represent virtual objects or segments in front of the vehicle 100.

[0037] In ACC control, if the preceding vehicle 400 is not detected, or if there is a sufficient distance between the preceding vehicle 400 and vehicle 100, control is executed to drive vehicle 100 at the set speed. In this case, the target speed is equal to the set speed. The vehicle ECU installed in vehicle 100 executes driving control to drive vehicle 100 at the target speed.

[0038] The vehicle ECU performs deceleration control when the distance between vehicle 100 and the preceding vehicle 400 decreases. The vehicle ECU decelerates vehicle 100 to maintain the necessary distance between vehicle 100 and the preceding vehicle 400, causing vehicle 100 to follow the preceding vehicle 400.

[0039] Figure 7 shows the virtual image Vi when the distance to the preceding vehicle 400 decreases compared to Figure 6. The object image 70 is closer to the vehicle image 20 along the depth direction based on the second vanishing point Vp2 than it was in Figure 6. Also, the multiple graphic images 60 are closer to each other along the depth direction compared to the state in Figure 6. By changing the position and size of the object image 70 based on the second vanishing point Vp2, it is possible to display the object image 70 at an appropriate size while providing the driver 200 with information about the change in the distance between vehicles.

[0040] Next, other examples of the second image G2 will be described with reference to Figures 8 to 12. Figure 8 shows the virtual image Vi when route guidance is provided to the driver 200. As shown in Figure 8, the virtual image Vi is displayed superimposed on the view Sc in front of the vehicle 100. The illustrated virtual image Vi is displayed superimposed on the road surface in front of the vehicle 100. In this case, the display device 3 projects the image onto the lower part of the windshield 110.

[0041] As shown in Figure 9, the virtual image Vi includes a first image G1 and a second image G2. The first image G1 has at least one guide image 50. The guide image 50 is an image in which depth is represented based on a third vanishing point Vp3 that is different from the first vanishing point Vp1. The third vanishing point Vp3 is shifted in the lateral direction Gh of the image relative to the first vanishing point Vp1.

[0042] The guidance image 50 in Figure 9 is displayed along the left line image 30L. When the guidance image 50 is displayed along the left line image 30L, the third vanishing point Vp3 is located to the left of the first vanishing point Vp1 in the horizontal direction Gh of the image. This improves the visibility of the guidance image 50, as will be explained below.

[0043] When the virtual image Vi includes multiple guidance images 50, the multiple guidance images 50 are displayed partially overlapping. The virtual image Vi in Figure 9 includes images 51, 52, and 53 as guidance images 50. The three images 51, 52, and 53 are displayed aligned in the depth direction based on the third vanishing point Vp3 and partially overlapping. The illustrated guidance image 50 is an image that guides the direction of travel at a fork in the road ahead. The guidance image 50 in Figure 9 is an image that guides the driver 200 to turn left at the third fork in the road from the current position.

[0044] Image 51 is positioned at the foreground of the three guide images 50, along the left line image 30L. Image 53 is positioned at the farthest point of the three guide images 50, along the left line image 30L. The three guide images 50 are, for example, arranged at equal intervals along the left line image 30L.

[0045] The three images 51, 52, and 53 each have a lower left corner 51c, 52c, and 53c, respectively. The corner 52c of image 52 and the corner 53c of image 53 are aligned along a virtual line L1. The virtual line L1 is a line segment connecting the corner 51c of image 51 to the third vanishing point Vp3. The virtual line L1 connecting the three corners 51c, 52c, and 53c extends in a direction that intersects with the left line image 30L. The guide image 50 in this embodiment is displayed in such a way that the alignment direction of the corners 51c, 52c, and 53c is difficult for the user to recognize.

[0046] As shown in Figure 10, Image 51 is positioned so that its lower left corner 51c aligns with the right edge 30a of the left line image 30L. Image 51 overlaps Image 52 so as to hide its lower left corner 52c. Image 51 overlaps corner 52c and the left line image 30L near corner 52c so that the positional relationship between corner 52c and the left line image 30L is difficult to perceive. As shown in Figure 11, the position of corner 52c in Image 52 is shifted to the left relative to the right edge 30a of the left line image 30L. However, because corner 52c is hidden by Image 51, this shift is not noticeable and is difficult for the user to perceive.

[0047] Similarly, image 52 overlaps image 53 in such a way that it obscures the lower left corner 53c of image 53. Image 52 overlaps corner 53c and the left line image 30L in the vicinity of corner 53c so that the positional relationship between corner 53c and the left line image 30L is difficult to perceive. As shown in Figure 11, the position of corner 53c in image 53 is shifted to the left relative to the left line image 30L. However, because corner 53c is obscured by image 52, this shift is not noticeable and is difficult for the user to perceive. According to the guide image 50 of this embodiment, the three images 51, 52, and 53 cover the left line image 30L, making it difficult for the user to notice the existence of the third vanishing point Vp3.

[0048] The visibility of the guide image 50 is improved when it is generated based on the third vanishing point Vp3. For example, if the guide image 50 is generated based on the first vanishing point Vp1, images 52 and 53 will move closer to the center of the horizontal Gh of the image, narrowing the space in the central part. In contrast, by positioning the guide image 50 based on the third vanishing point Vp3, the space in the central part is made more effective use of.

[0049] For example, as shown in Figure 12, in addition to the guidance image 50, other content images 80 may be displayed. The content image 80 is an image that provides information. The content image 80 may be a route guidance image, an object image 70, a warning or attention-grabbing image, or any other image. The content image 80 is positioned, for example, in the center of the horizontal Gh of the image. By positioning the guidance image 50 based on a third vanishing point Vp3, an appropriate gap is formed between the guidance image 50 and the content image 80. This improves the visibility of both the guidance image 50 and the content image 80.

[0050] Furthermore, the third vanishing point Vp3 may be shifted not only in the horizontal direction Gh relative to the first vanishing point Vp1, but also above the vertical direction Gv. Figure 13 shows a third vanishing point Vp3 located to the left of the first vanishing point Vp1 in the horizontal direction Gh, and above the first vanishing point Vp1 in the vertical direction Gv. In this case, it is possible to increase the display size of the guide image 50 displayed on the far side in the depth direction.

[0051] As described above, the vehicle display device 1 of this embodiment includes a display device 3 and a control unit 10 that controls the display device 3. The display device 3 displays an image to the driver 200 of the vehicle 100. The image displayed by the display device 3 includes a first image G1 and a second image G2. The first image G1 is an image that simulates the scenery in front of the vehicle 100 and expresses depth based on a first vanishing point Vp1. The second image G2 is an information-providing image that is displayed in the same area GR as the display area GR of the first image G1. The second image G2 is an image that expresses depth based on vanishing points Vp2 and Vp3, which are different from the first vanishing point Vp1.

[0052] According to the vehicle display device 1 of this embodiment, the depth of the second image G2 is represented based on vanishing points Vp2 and Vp3, which are different from the first vanishing point Vp1. By shifting the vanishing points Vp2 and Vp3 of the second image G2 relative to the first vanishing point Vp1, it is possible to improve the visibility of the image.

[0053] The second image G2 includes, for example, an object image 70 showing a forward object, which is an object detected in front of the vehicle 100. The object image 70 is an image in which depth is represented based on the second vanishing point Vp2. The second vanishing point Vp2 is located above the vertical direction Gv of the image relative to the first vanishing point Vp1. In this case, the display size of the second image G2 is prevented from becoming too small.

[0054] The first image G1 includes, for example, a line image 30 which represents the boundary of the lane on which the vehicle 100 travels. The second image G2 may include a guidance image 50 displayed along the line image 30. The guidance image 50 is an image in which depth is represented based on a third vanishing point Vp3 which is different from the first vanishing point Vp1. The third vanishing point Vp3 is shifted in the horizontal direction Gh relative to the first vanishing point Vp1. This makes it possible to provide an appropriate spacing between the multiple images that are displayed.

[0055] The line image 30 may have a left line image 30L and a right line image 30R. The left line image 30L is a line image 30 that represents the left boundary of the lane. The right line image 30R is a line image 30 that represents the right boundary of the lane. When the guide image 50 is displayed along the left line image 30L, the third vanishing point Vp3 is located to the left of the first vanishing point Vp1 in the horizontal direction Gh of the image. When the guide image 50 is displayed along the right line image 30R, the third vanishing point Vp3 is located to the right of the first vanishing point Vp1 in the horizontal direction Gh of the image. This display prevents the guide image 50 from being too close to the center of the image.

[0056] [Modified examples of embodiments] The vehicle display device 1 may be configured to display the virtual image Vi at an angle. For example, the vehicle display device 1 may be configured to display an angled virtual image Vi, as shown in Figure 14. In the virtual image Vi of Figure 14, the upper part Vu is imaged at a position far from the driver 200 relative to the lower part Vd in the vertical direction Gv of the image. This angled virtual image Vi may be realized by the optical system of the display device 3. The angled virtual image Vi may be realized by tilting the display surface 4a of the image display unit 4, or by other means.

[0057] The content displayed in the guidance image 50 is not limited to route guidance arrows. The guidance image 50 may also include text information. The shape of the object image 70 is not limited to a shape that imitates a vehicle, but may be a cube, for example. The display position of the virtual image Vi is not limited to the position exemplified in the embodiment. For example, the virtual image Vi may be displayed superimposed on a point of attention in front of the vehicle 100. The point of attention may be, for example, another vehicle such as the preceding vehicle 400 or a pedestrian, or any other object. The reflective surface that reflects the display light Lt toward the driver 200 is not limited to the surface of the windshield 110. The reflective surface may be, for example, the reflective surface of a combiner, or the surface of any other reflective member.

[0058] The first image G1 is not limited to the line image 30. The image simulating the scenery in front of the vehicle 100 may be a building or other structure, a guardrail or road shoulder or other structure, or any other image.

[0059] The guide image 50 may be displayed along the right line image 30R. When the guide image 50 is displayed along the right line image 30R, the third vanishing point Vp3 is located to the right of the first vanishing point Vp1 in the horizontal direction Gh of the image.

[0060] The display device 3 may be a device that displays the real images of the first image G1 and the second image G2 to the driver. In this case, the display device 3 may be, for example, a meter device.
