Before describing the present invention specifically, an outline will be given first. Example 1 of this invention is related with the display apparatus for vehicles which displays information as an instrument panel of a vehicle. The vehicle display device includes two types of display panels having different display directions on the display surface. The two types of display panels use display panels having different display areas, and either one of the two types of display panels is used facing the user in accordance with the display purpose. In the first embodiment, a display panel having a larger display surface area is referred to as a first display panel, and a display panel having a smaller display surface area is described as a second display panel. The vehicle display device displays information on one of the first display panel and the second display panel facing the driver in accordance with the traveling state of the vehicle. Here, the vehicle display device has the first display panel opposed to the windshield when the second display panel is opposed to the driver, and the image displayed on the first display panel is the windshield. Reflected and used as a head-up display.

FIG. 1 is an external view of a vehicle interior in which a vehicle display device 100 according to a first embodiment of the present invention is mounted as viewed from the rear. As shown in FIG. 1, a rectangular coordinate system composed of an x-axis, a y-axis, and a z-axis is defined. The x-axis extends in the vehicle length direction, the y-axis extends in the vehicle width direction, and the z-axis extends in the vehicle height direction. Further, the positive directions of the x-axis, y-axis, and z-axis are each defined in the direction of the arrow in FIG. 1, and the negative direction is defined in the direction opposite to the arrow. Here, the positive direction of the x-axis is the direction from the steering wheel 206 in FIG. 1 toward the driver's seat, sometimes referred to as “front side”, and the negative direction of the x-axis is from the steering wheel 206 in FIG. It is the direction to go, sometimes called the “back side”. Further, the positive direction of the z-axis may be referred to as “upper surface side”, and the negative direction of the z-axis may be referred to as “lower surface side”.

Since the description of the present embodiment will be described as an example of a vehicle in which the steering wheel 206 is arranged on the right side of the vehicle, the steering wheel 206 is arranged on the positive direction side of the y-axis in front of the vehicle interior. Therefore, a driver's seat (not shown) is also arranged on the positive direction side of the y axis, and the passenger seat is arranged on the negative direction side of the y axis. The steering wheel 206 and the driver's seat may be arranged on the negative direction side of the y axis. Further, the vehicle display device 100 is disposed on the x-axis negative direction side of the steering wheel 206, and the vehicle display device 100 is attached to the dashboard 204. The vehicle display device 100 has a function of an instrument panel.

The windshield 202 is disposed on the negative side of the dashboard 204 in the x-axis direction, and the rear view mirror 200 is disposed on the positive side of the windshield 202 in the z-axis direction. Furthermore, a navigation screen 210 is installed on the negative side of the steering wheel 206 in the y-axis direction, for example, on the center console 208. The navigation screen 210 is a screen of a vehicle-mounted navigation terminal device, and displays an image of a car navigation system.

FIG. 2 is another external view of the interior of the vehicle in which the vehicle display device 100 is mounted as viewed from the rear. 2 is configured in the same manner as FIG. 1, but the shape of the vehicle display device 100 is different from that in FIG. 1. Although the shape of the vehicle display device 100 in FIGS. 1 and 2 will be described later, the vehicle display device 100 changes the shape when the vehicle interior is viewed from the rear as shown in FIGS. 1 and 2. In addition, the HUD region 220 is displayed on the positive side of the z-axis of the vehicle display device 100 and on the windshield 202. The HUD area 220 is a display area in the head-up display, and is formed by the vehicle display device 100.

FIG. 3 shows a configuration of the vehicle display device 100. The vehicle display device 100 includes a changing unit 10, a first display panel 16, and a second display panel 18. The change unit 10 includes a drive control unit 24, a drive unit 26, and a display control unit 28. The control unit 14 includes a drive control unit 24 and a display control unit 28.

The first display panel 16 is configured using a display element such as an LCD (Liquid Crystal Display), for example, a TFT (Thin Film Transistor) liquid crystal. In this embodiment, a combination in which the area of the display surface of the first display panel 16 is larger than the area of the display surface of the second display panel 18 is used. The 1st display panel 16 has a function of an instrument panel, and displays it centering on information about operation of vehicles. The information related to the operation of the vehicle includes a traveling speed indicating the traveling state of the vehicle, an engine speed, shift position information, and navigation information indicating a traveling direction. Hereinafter, a form in which the first display panel 16 is used to display the instrument panel is referred to as a “first display form”. FIG. 4 is a front view showing a first display form by the vehicle display device 100. This corresponds to an enlarged view of the vicinity of the vehicle display device 100 in FIG. The 1st display panel 16 is arrange | positioned so that the user who is seated in the driver's seat can see visually. As described above, the first display panel 16 displays information in a state where the display surface is opposed to the user in the first display form, that is, in a state of being not stored in the dashboard 204 of the vehicle. The periphery of the first display panel 16 is fixed to the frame part 300.

FIG. 5 shows an example of a screen displayed on the first display panel 16. A circular rotation speed display unit 406 is disposed at the center portion of the first display panel 16, and a speed display unit 408 is disposed at the circular center portion of the rotation speed display unit 406. An oil temperature display unit 400, a fuel display unit 402, and a water temperature display unit 404 are arranged on the left side of the rotation speed display unit 406. Furthermore, a shift position display unit 410 and other information display unit 412 are arranged on the right side of the rotation speed display unit 406. The other information display unit 412 shows, for example, a clock and a thermometer. Since the content displayed on each display is a known technique, the description is omitted here. Returning to FIG.

The display control unit 28 generates the content to be displayed on the first display panel 16, that is, an image in which the other information display unit 412 is displayed from the oil temperature display unit 400 (hereinafter referred to as “first display form image”). The generated first display form image is displayed on the first display panel 16. The first display form image is displayed when the driver is facing the driver, such as a state where the first display panel 16 is exposed, during normal driving. The first display form image generated by the display control unit 28 includes travel distance, turn-by-turn, map in the navigation system, video camera video (each azimuth camera, camera composite video, infrared camera). May be included.

As with the first display panel 16, the second display panel 18 is configured using a display element such as an LCD, and is configured by, for example, a TFT liquid crystal. In the present embodiment, the area of the display surface of the second display panel 18 is smaller than the area of the display surface of the first display panel 16. Similarly to the first display panel 16, the second display panel 18 has the function of an instrument panel and displays information related to the operation of the vehicle. However, since the display area of the second display panel 18 is smaller than the display area of the first display panel 16, the minimum necessary information is displayed among the information related to the operation of the vehicle. Here, the display surface of the second display panel 18 faces the user when the first display panel 16 is not facing the user, such as when the first display panel 16 is stored in the dashboard 204 of the vehicle. At that time, the display surface of the first display panel 16 is directed upward, which is the positive direction side of the z-axis. On the other hand, the display surface of the second display panel 18 does not face the user when the first display panel 16 is not stored in the dashboard 204 of the vehicle. That is, the second display panel 18 and the first display panel 16 are arranged in different directions, and only one of them faces the user.

Hereinafter, a form in which the second display panel 18 functions as an instrument panel is referred to as a “second display form”. The second display form is a display form that is simpler than the first display form and does not require time for visual observation, or enables visual observation of information without gazing. This will be described later.

FIG. 6 is a front view showing a second display form by the vehicle display device 100. This corresponds to an enlarged view of the vicinity of the vehicle display device 100 in FIG. The 2nd display panel 18 is arrange | positioned so that the user who is seated in the driver's seat can see visually. The periphery of the second display panel 18 is fixed to the frame part 300. Here, the display area of the second display panel 18 is smaller than the display area of the first display panel 16. As described above, the HUD region 220 generated by the vehicle display device 100 is displayed on the windshield 202. The generation of the HUD area 220 will be described later.

FIG. 7 shows an example of a screen displayed on the second display panel 18. A rotation speed display section 422 is arranged at the center of the second display panel 18, a speed display section 420 is arranged on the left side of the rotation speed display section 422, and a shift position display section 424 is placed on the right side of the rotation speed display section 422. Is placed. Since the content displayed on each display is a known technique, the description is omitted here. Returning to FIG.

The display control unit 28 generates contents to be displayed on the second display panel 18, that is, an image (hereinafter referred to as “second display form image”) in which the shift position display unit 424 is displayed from the speed display unit 420, The generated second display form image is displayed on the second display panel 18. As described above, since the display area of the second display panel 18 is smaller than the display area of the first display panel 16, the amount of information displayed on the second display form image is the same as that of the first display form image. Less than the amount of information displayed. The second display form image is displayed when the second display panel 18 is exposed except during normal driving. The second display form image generated by the display control unit 28 may include a shift change indicator, as long as it includes at least the traveling speed of the vehicle.

Thus, the display control unit 28 causes the second display panel 18 to display the second display form image, and causes the first display panel 16 to display information such that the display content is reflected upward. Information such that the display content is reflected upward is information to be displayed in the above-described HUD region 220 and information to be displayed as a head-up display. Since it is displayed as a head-up display, the display control unit 28 displays information as a mirror image on the first display panel 16 in the second display mode. Further, the display control unit 28 makes the luminance of the first display panel 16 in the second display mode higher than the luminance of the first display panel 16 in the first display mode.

The drive control unit 24 controls the operation of the drive unit 26 in order to change the display form so that one of the first display panel 16 and the second display panel 18 faces the user. To explain a specific example, the drive control unit 24 receives engine information from an ECU (Electronic Control Unit) that controls the operation of the engine. When the engine information indicates engine stop, the drive control unit 24 realizes the second display mode. On the other hand, when any of the following conditions is met, the drive control unit 24 realizes the first display mode. The conditions are (1) when the door on the driver's seat side is opened, (2) when the user is seated on the driver's seat, (3) when the user sits on the driver's seat and fastens the seat belt, and (4) engine These states are detected by a sensor (not shown) and input to the drive control unit 24. Furthermore, the drive control part 24 may implement | achieve a 2nd display form, when the driving speed becomes higher than a threshold value in the condition where the 1st display form is implement | achieved. Note that either the first display mode or the second display mode may be selected by the user operating a switch (not shown).

When realizing the first display mode, the drive control unit 24 causes the first display panel 16 to face the user and the second display panel 18 to face the user in order to use the first display panel 16. On the other hand, when the second display mode is realized, the drive control unit 24 uses the second display panel 18 so that the second display panel 18 faces the user and the first display panel 16 does not face the user. Let More specifically, the drive control unit 24 turns the first display panel 16 upward. Therefore, when the display mode should be changed, the drive control unit 24 executes a change from the first display mode to the second display mode, or executes a change from the second display mode to the first display mode. .

The drive unit 26 is connected to the drive control unit 24 and receives an instruction from the drive control unit 24. The drive unit 26 executes a change between the first display form and the second display form in accordance with the received instruction. The arrangement relationship between the first display panel 16 and the second display panel 18 and the change mechanism between the first display form and the second display form are arbitrary, but here, in order to explain the operation of the drive unit 26 8 (a)-(e) are used. FIGS. 8A to 8E are side views showing the state of change of the display form by the vehicle display device 100. FIG. FIG. 8A is a side view of the vehicle display device 100 in the first display mode. The vehicle display device 100 includes a frame portion 300, a first shaft 302, a second shaft 304, a drive portion 26, a slide slide shaft 310, and a display panel storage portion 312. Further, the first display panel 16 and the second display panel 18 are attached to the frame part 300.

The display panel storage 312 is arranged on the negative side of the x axis, that is, on the back side. A rod-like slide sliding shaft 310 extending in the x-axis direction is fixed to the positive side of the z-axis of the display panel storage unit 312, that is, the upper surface side. A rack gear (not shown) provided in parallel with the slide sliding shaft 310 is provided. The drive unit 26 is attached to the slide slide shaft 310. The drive unit 26 includes a motor (not shown) and a pinion gear of the motor. When a rotational force is applied to the pinion gear by the rotation of the motor of the drive unit 26, the rack gear moves in the x-axis direction along the slide slide shaft 310 in the drive unit 26. Therefore, the drive unit 26 slides in the x-axis direction along the slide slide shaft 310.

The drive unit 26 is also provided with a first shaft 302, and the frame unit 300 is rotatably attached via the first shaft 302. The drive unit 26 includes a motor (not shown), and rotates the frame unit 300 about the first shaft 302 as a rotation axis by the motor and a gear mechanism. The frame part 300 arranges the first display panel 16 and the second display panel 18 on different surfaces. In FIG. 8A, the first display panel 16 is disposed on the front side of the frame part 300, and the second display panel 18 is disposed on the lower surface side of the frame part 300. Therefore, at least a part of the first display panel 16 is interposed between the user and the vehicle front view in the first display form, and the second display panel 18 is provided between the user and the vehicle dashboard 204 in the first display form. It intervenes between. The frame 300 is also provided with a second shaft 304 along with the first shaft 302.

8 (b) to 8 (d), when the drive unit 26 is driven, the frame unit 300 is rotated about the first shaft 302. At that time, the drive unit 26 moves to the negative direction side of the x axis. When the rotation of the frame part 300 started from FIG. 8A is completed, the state shown in FIG. In FIG. 8D, the frame part 300 is arranged so that the second display panel 18 faces the front side and the first display panel 16 faces the upper side.

8 (d) to 8 (e), the drive unit 26 does not rotate the frame unit 300 and moves the slide slide shaft 310 in the negative direction of the x-axis. As the drive unit 26 moves, the frame unit 300 also moves in the negative direction of the x-axis and enters the display panel storage unit 312. Note that the upper side surface of the display panel storage unit 312 is open. FIG. 8E is a side view of the vehicle display device 100 in the second display mode. Thus, when the change from the first display form to the second display form is executed, the vehicle display device 100 operates in the order from FIG. 8A to FIG. 8E. On the other hand, when the change from the second display mode to the first display mode is executed, the vehicular display device 100 operates in the order from FIG. 8 (e) to FIG. 8 (a). With the operation from FIG. 8A to FIG. 8E, the first shaft 302 and the second shaft 304 are grooves corresponding to the trajectories of the respective shafts provided inside the side wall of the display panel storage unit 312. Engage and move.

FIGS. 9A to 9B are side views showing a second display form by the vehicle display device 100. FIG. Here, in order to clarify the configuration as a head-up display, a windshield 202, a dashboard 204, and a frame 300 are shown. The dashboard 204 is provided with a transmission part 222. The transmission unit 222 transmits the image from the first display panel 16 in order to realize a head-up display. The transmission unit 222 includes an opening, a transmission plate, an electronic shutter, and the like. When an electronic shutter is used, light is transmitted when performing the function as a head-up display, and light is not transmitted in other cases.

FIG. 9A corresponds to the case of the configuration of FIG. An image from the first display panel 16 is transmitted through the transmission unit 222 and reflected by the windshield 202. A HUD region 220 is formed at a position reflected by the windshield 202. Here, the HUD region 220 is positioned at the center in the vertical direction of the windshield 202, and a reflected image is displayed in the HUD region 220. The user can view the reflected image displayed in the HUD area 220. In this case, the display control unit 28 temporarily displays necessary information, for example, a warning, instead of displaying information necessary for driving the vehicle. The warning may be a text telop. The reflection for the head-up display is not limited to the windshield 202, and may be reflection by a combiner. In FIG. 9A, the first display panel 16 faces the positive direction of the z-axis due to the arrangement of the frame part 300. However, when the image from the first display panel 16 is used as a head-up display, the first display is displayed. It is preferable to arrange the frame portion 300 at an angle at which the image of the panel 16 is reflected by the windshield 202 and is visible to the user. Such an angle varies depending on the inclination angle of the windshield 202. Further, since adjustment is also required depending on the viewpoint position of the user, it is preferable that the angle of the frame 300 can be finely adjusted.

FIG. 9B shows the second display form, but the angle at which the frame part 300 is arranged is different from FIG. 9A. Here, the HUD area 220 is located below the windshield 202, and a reflected image is displayed in the HUD area 220. In this case, the display control unit 28 performs the minimum display necessary for the operation of the vehicle, such as speed display by numbers and simple navigation information (direction arrow). The display control unit 28 may always display such information.

9 (a) and 9 (b) may be switched according to information displayed in the HUD area 220. For example, in the state shown in FIG. 9B, the HUD area 220 is set at a position where the windshield is low when viewed from the user, so that a simple map such as turn-by-turn is displayed. When it is necessary to present a warning to the user, the warning is displayed at a position where the windshield is high as viewed from the user as shown in FIG.

This configuration can be realized in terms of hardware by a CPU, memory, or other LSI of any computer, and in terms of software, it can be realized by a program loaded in the memory, but here it is realized by their cooperation. Draw functional blocks. Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

According to the embodiment of the present invention, since the first display mode is changed between the first display mode in which the first display panel faces the user and the second display mode in which the second display panel faces the user, the information suitable for the driving situation. Can be displayed. Further, in the second display mode, information is displayed on the second display panel, and information on which the display content is reflected is displayed on the first display panel, so that a head-up display can be realized. In addition, the first display panel displays information facing the user in the first display form and realizes a head-up display in the second display form, thereby suppressing an increase in the scale of the apparatus for realizing the head-up display. it can.

Also, since the warning is displayed by the head-up display, it is possible to prompt attention by the warning. In addition, since the information is displayed as a mirror image on the first display panel in the second display mode, a head-up display can be realized. Moreover, since the brightness | luminance of the 1st display panel in a 2nd display form is made higher than the brightness | luminance of the 1st display panel in a 1st display form, the visibility in the case of a head-up display can be improved.

(Example 2)
Next, Example 2 will be described. As in the first embodiment, the second embodiment also relates to a vehicle display device that displays information as a vehicle instrument panel. In Example 2, a display panel having a smaller display surface area is referred to as a first display panel, and a display panel having a larger display surface area is referred to as a second display panel. In Example 2, in the first display mode, the display surface of the first display panel faces the user and the display surface of the second display panel does not face the user. In the second display mode, the display surface of the second display panel faces the user and the display surface of the first display panel faces upward to display the head-up display. Here, it demonstrates centering on the difference with Example 1. FIG.

FIG. 10 is an external view of a vehicle interior in which the vehicle display device 100 according to the second embodiment of the present invention is mounted as viewed from the rear. FIG. 10 is configured in the same manner as FIG. 1, but the HUD region 220 is displayed on the windshield 202 on the positive side of the z-axis of the vehicle display device 100. As described above, the HUD region 220 is a display region in the head-up display and is formed by the vehicle display device 100. FIG. 11 is another external view of a vehicle interior in which the vehicle display device 100 is mounted as viewed from the rear. FIG. 11 is configured in the same manner as FIG. 2, but the HUD area 220 is not displayed.

12 (a) to 12 (b) are side views showing a second display form by the vehicle display device 100 according to the second embodiment of the present invention. FIG. 12A shows a configuration corresponding to FIG. Here, it arrange | positions so that the 2nd display panel 181 may face the front side, and the 1st display panel 161 may face the upper surface side. The image from the first display panel 161 is transmitted through the transmission unit 222 and reflected by the windshield 202 (not shown). A HUD region 220 is formed at a position reflected by the windshield 202. Even in this case, the HUD region 220 is located above the windshield 202, and the reflected image is displayed in the HUD region 220. FIG. 12B is a configuration corresponding to FIG. 9B, and the angle at which the frame portion 300 is disposed is different from that in FIG. Even in this case, the HUD region 220 is located below the windshield 202, and the reflected image is displayed in the HUD region 220.

FIG. 13 is a side view showing a first display form by the vehicle display device 100 according to the second embodiment of the present invention. Here, it arrange | positions so that the 1st display panel 161 may face the front side, and the 2nd display panel 181 may face the lower surface side.

According to the embodiment of the present invention, since the head-up display is realized by the display image of the first display panel 161 in the second display mode, when performing display as the head-up display, as an instrument panel facing the user The amount of information that can be displayed can be increased. In addition, since the head-up display is realized in the second display mode, the degree of freedom in configuration can be improved.

In the second embodiment, the first display panel 161 is used for HUD display. Since the first display panel 161 has a smaller area than the first display panel 16 described in the first embodiment, warnings, text telops, and the like are appropriate for the contents displayed in the HUD region 220. That is, in the second embodiment, the first display panel 161 plays the role of the first display panel 16 of the first embodiment, and the second display panel 181 plays the role of the second display panel 18 of the first embodiment. In the second embodiment, the display form corresponding to the first display form of the first embodiment is such that the first display panel 161 faces the user, and the display form corresponding to the second display form of the first embodiment is The second display panel 181 faces the user, and information is displayed on the first display panel 161 so that the display content is reflected upward.

12 (a) and 12 (b) may be switched according to information displayed in the HUD area 220. For example, in the state of FIG. 12B, since the HUD area 220 is set at a position where the windshield is low as viewed from the user, text such as e-mail received text and road traffic information is displayed as a telop.
