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 capable of displaying an image with a sense of depth while suppressing a decrease in visibility.

Means for Solving the Problems

[0006] The display device for a vehicle according to the present invention includes a display device that displays an image for a driver of the vehicle, and a control unit that controls the display device. The image displayed by the display device includes a first image and a second image. The first image is an image imitating the scenery in front of the vehicle and having a depth represented based on a first vanishing point. The second image is an information-providing image displayed within the same area as the display area of the first image and having a depth represented based on a vanishing point different from the first vanishing point.

[0009] Hereinafter, a vehicle display device according to an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to this embodiment. Also, the components in the following embodiments include those that can be easily assumed by those skilled in the art or those that are substantially the same.

[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 scene 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 scene 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] In FIGS. 1 and 2, an example of the vehicle display device 1 according to this embodiment is shown. The vehicle display device 1 of this embodiment has a display device 3 that displays an image for 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 for the driver 200. As shown in FIG. 2, the vehicle display device 1 displays the virtual image Vi for 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 accommodated, for example, below the dashboard 120. The display device 3 and the control unit 10 are accommodated 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 viewed from the driver 200.

[0018] The control unit 10 shown in FIG. 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 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, for example, a program stored in the memory or the like of the display device 3.

[0019] The control unit 10 acquires various information regarding the vehicle 100 from a vehicle ECU or the like that controls the vehicle 100. The information acquired by the control unit 10 includes, for example, the traveling speed of the vehicle 100, the shift position of the vehicle 100, route guidance information by a navigation system, the position information of the vehicle 100, information regarding the battery of the vehicle 100, and information regarding 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. FIG. 3 shows an example of the first image G1 and the second image G2. Both the first image G1 and the second image G2 of the present embodiment are displayed in the same display area GR. The shape of the display area GR is, for example, rectangular.

[0021] The first image G1 is an image imitating the scenery in front of the vehicle 100. The first image G1 is an image in which the depth based on the first vanishing point Vp1 is expressed. The exemplified first vanishing point Vp1 is arranged above the image vertical direction Gv with respect 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 FIG. 3. The line image 30 is an image representing the boundary of the lane in which the vehicle 100 travels. The line image 30 is a linear image extending toward the first vanishing point Vp1.

[0023] The line image 30 has a left line image 30L and a right line image 30R. The left line image 30L is an image representing the left boundary in the lane in which the vehicle 100 travels. The left line image 30L is displayed on the left side of the vehicle image 20, which is an image showing the vehicle 100, in the horizontal image direction Gh. The right line image 30R is an image representing the right boundary in the above lane. The right line image 30R is displayed on the right side of the vehicle image 20 in the horizontal image direction Gh. The interval between the two line images 30L and 30R becomes narrower as it goes upward in the vertical image direction Gv.

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

[0025] The front object 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 inter-vehicle distance to the preceding vehicle 400. When the inter-vehicle distance increases, the object image 70 moves to the back side in the depth direction based on the second vanishing point Vp2 as indicated by the arrow AR1. Conversely, when the inter-vehicle distance decreases, the object image 70 moves to the front side in the depth direction based on the second vanishing point Vp2 as indicated by the arrow AR2.

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

[0027] On the other hand, the object image 70 generated based on the second vanishing point Vp2 can be displayed in 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 when the object image 70 moves along the depth direction becomes gentle. Therefore, the vehicle display device 1 of the present embodiment can perform information display with a sense of depth while ensuring the visibility of the object image 70.

[0028] Also, the distance between the left line image 30L and the right line image 30R is widened so that the user hardly feels a sense of discomfort with respect to the object image 70. As shown in FIG. 3, the left line image 30L and the right line image 30R are arranged so as not to intersect 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] Since the line image 30 does not intersect the trajectory L70, the user hardly feels a sense of discomfort with respect to the display size of the object image 70. Therefore, the vehicle display device 1 of the present embodiment can produce a natural sense of depth while making two images G1 and G2 with different vanishing points coexist in the same display area GR.

[0030] FIGS. 5 and 6 show a virtual image Vi when the vehicle 100 is trying to catch up with the preceding vehicle 400. As shown in FIG. 5, the virtual image Vi is displayed superimposed on the scenery Sc in front of the vehicle 100. As shown in FIG. 6, the first image G1 of the virtual image Vi includes the left line image 30L and the right line image 30R. The second image G2 of the virtual image Vi includes the vehicle image 20 and the object image 70. The virtual image Vi further includes a speed image 21, a set value image 22, and a plurality of graphic images 60.

[0031] The speed image 21 is an image showing the traveling speed of the vehicle 100, for example, an image of characters indicating the speed. The speed image 21 is always displayed, for example, when the vehicle 100 is in the driving mode. The object image 70 is an image showing the preceding vehicle 400 and is an image imitating the shape of a vehicle. The object image 70 showing the preceding vehicle 400 is displayed, for example, during the execution of ACC control. The object image 70 is, for example, an image of a bird's-eye view of the vehicle from behind the vehicle.

[0032] As shown in FIG. 6, the vehicle image 20 and the object image 70 are drawn in a perspective based on the second vanishing point Vp2. During the execution of ACC control, further, the set value image 22 and the graphic image 60 are displayed. The set value image 22 is the set value of the traveling speed in ACC control. In the following description, the set value of the traveling speed in ACC control is simply referred to as the set speed. The set value image 22 is arranged above the speed image 21 in the image 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 arranged side by side in the depth direction based on the first vanishing point Vp1, or may be arranged side by side in the depth direction based on the second vanishing point Vp2.

[0033] The graphic image 60 is an image that three-dimensionally represents changes in the inter-vehicle distance and the like in ACC control. The shape of the graphic image 60 in the present embodiment is a rectangle. The graphic image 60 in FIG. 6 has the image 61, the image 62, and the image 63. The three graphic images 60 are displayed with partial overlap. The relative positions of the three graphic images 60 change according to the target value of the inter-vehicle distance and the like.

[0034] The three graphic images 60 are arranged side by side, for example, along a line heading toward the first vanishing point Vp1. The graphic image 60 may be arranged along a line heading toward the second vanishing point Vp2. The graphic image 60 is displayed between the vehicle image 20 and the object image 70. The image 61 is arranged at the most front position among the three graphic images 60. The image 63 is arranged at the most rear position among the three graphic images 60. The three graphic images 60 are arranged at equal intervals, for example, along the depth direction based on the vanishing points Vp1 and Vp2.

[0035] Among the plurality of graphic images 60, the graphic image 60 displayed closest to the front is larger than the other graphic images 60. Among the plurality of graphic images 60, the graphic image 60 displayed farthest to the back is smaller than the other graphic images 60. Further, when three or more graphic images 60 are displayed, the graphic images 60 become smaller as they go from the front side toward the vanishing points Vp1 and Vp2 on the back side.

[0036] The image 61 of the present embodiment is displayed such that a vehicle image 20 overlaps a part of the image 61. That is, a part of the image 61 is hidden by the vehicle image 20. With such a display, it is easy for the driver 200 to understand that the plurality of graphic images 60 indicate virtual objects or segments in front of the vehicle 100.

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

[0038] When the vehicle ECU detects that the distance between the vehicle 100 and the preceding vehicle 400 has decreased, it performs deceleration control. The vehicle ECU decelerates the vehicle 100 so as to ensure a necessary distance between the vehicle 100 and the preceding vehicle 400, and causes the vehicle 100 to follow the preceding vehicle 400.

[0039] FIG. 7 shows a virtual image Vi when the distance to the preceding vehicle 400 has decreased with respect to FIG. 6. The object image 70 has approached the vehicle image 20 from the position in FIG. 6 along the depth direction based on the second vanishing point Vp2. Further, the plurality of graphic images 60 have approached each other along the depth direction as compared with the state in FIG. 6. By changing the position and size of the object image 70 based on the second vanishing point Vp2, it is possible to provide information about the change in the inter-vehicle distance to the driver 200 while displaying the object image 70 in an appropriate size.

[0040] Next, with reference to FIGS. 8 to 12, another example of the second image G2 will be described. FIG. 8 shows a virtual image Vi when route guidance is provided for the driver 200. As shown in FIG. 8, the virtual image Vi is displayed superimposed on the scenery Sc in front of the vehicle 100. The illustrated virtual image Vi is displayed so as to overlap the road surface in front of the vehicle 100. In this case, the display device 3 projects an image at the lower part of the windshield 110.

[0041] As shown in FIG. 9, the virtual image Vi includes the first image G1 and the second image G2. The first image G1 has at least one guidance image 50. The guidance image 50 is an image in which the depth based on a third vanishing point Vp3 different from the first vanishing point Vp1 is expressed. The third vanishing point Vp3 is shifted in the image horizontal direction Gh with respect to the first vanishing point Vp1.

[0042] The guidance image 50 in FIG. 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 on the left side of the image horizontal direction Gh with respect to the first vanishing point Vp1. Thereby, as will be described below, the visibility of the guidance image 50 is improved.

[0043] When the virtual image Vi includes a plurality of guidance images 50, the plurality of guidance images 50 are displayed partially overlapping. The virtual image Vi in FIG. 9 includes an image 51, an image 52, and an image 53 as the guidance image 50. The three images 51, 52, and 53 are arranged in the depth direction based on the third vanishing point Vp3 and are displayed partially overlapping. The illustrated guidance image 50 is an image for guiding the traveling direction at a forward branch point. The guidance image 50 in FIG. 9 is an image for guiding the driver 200 to turn left at the third branch point from the current position.

[0044] Image 51 is arranged at the most front position along the left line image 30L among the three guide images 50. Image 53 is arranged at the most rear position along the left line image 30L among the three guide images 50. The three guide images 50 are arranged, for example, at equal intervals along the left line image 30L.

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

[0046] As shown in FIG. 10, image 51 is arranged such that the lower left corner 51c is along the right edge 30a in the left line image 30L. Image 51 overlaps image 52 so as to hide the lower left corner 52c of image 52. Image 51 overlaps the corner 52c and the left line image 30L near the corner 52c so that the positional relationship between the corner 52c and the left line image 30L is difficult to recognize. As shown in FIG. 11, the position of the corner 52c of image 52 is shifted to the left with respect to the right edge 30a of the left line image 30L. However, since the corner 52c is hidden by image 51, this shift is not conspicuous and is difficult for the user to recognize.

[0047] Similarly, image 52 overlaps image 53 so as to hide the lower left corner 53c of image 53. Image 52 overlaps the corner 53c and the left line image 30L near the corner 53c so that the positional relationship between the corner 53c and the left line image 30L is difficult to recognize. As shown in FIG. 11, the position of the corner 53c of image 53 is shifted to the left with respect to the left line image 30L. However, since the corner 53c is hidden by image 52, this shift is not conspicuous and is difficult for the user to recognize. According to the guide image 50 of the present embodiment, since the three images 51, 52, and 53 cover the left line image 30L, the presence of the third vanishing point Vp3 is difficult for the user to notice.

[0048] By generating the guidance image 50 based on the third vanishing point Vp3, the visibility of the guidance image 50 is improved. For example, when the guidance image 50 is generated based on the first vanishing point Vp1, the images 52 and 53 approach the center in the image horizontal direction Gh, narrowing the space in the central part. In contrast, by arranging the guidance image 50 based on the third vanishing point Vp3, the space in the central part is effectively utilized.

[0049] For example, as shown in FIG. 12, in addition to the guidance image 50, other content images 80 may be displayed. The content image 80 is an image for providing information. The content image 80 may be an image for route guidance, an object image 70, an image for attracting attention or warning, or other images. The content image 80 is arranged, for example, in the central part of the image horizontal direction Gh. By arranging the guidance image 50 based on the third vanishing point Vp3, an appropriate gap is formed between the guidance image 50 and the content image 80. Thereby, the visibility of the guidance image 50 and the content image 80 is improved respectively.

[0050] Note that the third vanishing point Vp3 may be shifted not only in the image horizontal direction Gh with respect to the first vanishing point Vp1 but also upward in the image vertical direction Gv. FIG. 13 shows a third vanishing point Vp3 that is located on the left side of the image horizontal direction Gh with respect to the first vanishing point Vp1 and on the upper side of the image vertical direction Gv with respect to the first vanishing point Vp1. In this case, it is possible to increase the display size of the guidance image 50 displayed on the back side in the depth direction.

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

[0052] According to the vehicle display device 1 of the present embodiment, the second image G2 expresses the depth based on vanishing points Vp2 and Vp3 different from the first vanishing point Vp1. By shifting the vanishing points Vp2 and Vp3 of the second image G2 with respect to the first vanishing point Vp1, it becomes possible to improve the visibility of the image.

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

[0054] The first image G1 includes, for example, a line image 30 that is an image expressing the boundary of the lane in 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 expressing the depth based on a third vanishing point Vp3 different from the first vanishing point Vp1. The third vanishing point Vp3 is shifted in the image horizontal direction Gh with respect to the first vanishing point Vp1. Thereby, it becomes possible to provide an appropriate interval between the plurality of displayed images.

[0055] The lane image 30 may have a left lane image 30L and a right lane image 30R. The left lane image 30L is a lane image 30 representing the left boundary in the lane. The right lane image 30R is a lane image 30 representing the right boundary in the lane. When the guidance image 50 is displayed along the left lane image 30L, the third vanishing point Vp3 is located on the left side of the image horizontal direction Gh with respect to the first vanishing point Vp1. When the guidance image 50 is displayed along the right lane image 30R, the third vanishing point Vp3 is located on the right side of the image horizontal direction Gh with respect to the first vanishing point Vp1. By such a display, it is suppressed that the guidance image 50 gets too close to the center of the image.

[0056] [Modification of the Embodiment] Note that the vehicle display device 1 may be configured to display the virtual image Vi in an inclined manner. For example, as shown in FIG. 14, the vehicle display device 1 may be configured to display an inclined virtual image Vi. In the virtual image Vi of FIG. 14, the upper part Vu forms an image at a position farther from the driver 200 with respect to the lower part Vd in the image vertical direction Gv. Such an inclined virtual image Vi may be realized by the optical system of the display device 3. The inclined virtual image Vi may be realized by inclining the display surface 4a of the image display unit 4, or may be realized by other means.

[0057] The content displayed on the guidance image 50 is not limited to the arrow for route guidance. The guidance image 50 may include character information. The shape of the object image 70 is not limited to the shape imitating a vehicle, and may be, for example, a cube. 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 an object to be noted in front of the vehicle 100. The object to be noted may be, for example, another vehicle such as the preceding vehicle 400 or a pedestrian, or may be other objects. The reflecting surface that reflects the display light Lt toward the driver 200 is not limited to the surface of the windshield 110. The reflecting surface may be, for example, the reflecting surface of a combiner, or may be the surface of other reflecting members.

[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 such as a building, an image simulating a structure such as a guardrail or a road shoulder, or other images.

[0059] The guidance image 50 may be displayed along the right line image 30R. When the guidance image 50 is displayed along the right line image 30R, the third vanishing point Vp3 is arranged on the right side 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 image of the first image G1 and the real image of the second image G2 to the driver. In this case, the display device 3 may be, for example, a meter device. The display device 3 that displays the real image is arranged in front of the driver 200 so that the display surface 4a is visible to the driver, for example.
