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.

  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, a second display panel 18, a GPS receiving unit 30, navigation data 32, an information acquiring unit 36, and a determining unit 38. The change unit 10 includes a drive control unit 24, a drive unit 26, and a display control unit 28, and the information acquisition unit 36 includes a navigation information acquisition control unit 42 and a current position acquisition control unit 44. The control unit 14 includes a drive control unit 24, a display control unit 28, an information acquisition unit 36, and a determination unit 38.

  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. The 1st display panel 16 has the function of an instrument panel, and displays the information used for driving | running | working of a vehicle. 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. 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 first display panel 16 is exposed during normal running. 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.

  Similar to the first display panel 16, the second display panel 18 is configured using a display element such as an LCD. For example, the second display panel 18 is composed of a TFT liquid crystal and has a function of an instrument panel. Displays information used. Here, the display surface of the second display panel 18 faces the user when the first display panel 16 is stored in the dashboard 204 of the vehicle. On the other hand, when the first display panel 16 is not stored in the dashboard 204 of the vehicle, the display surface of the second display panel 18 does not face the user. 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.

  Below, the form which uses the 2nd display panel 18 in order to display an instrument panel is called "2nd 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.

  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.

  The information acquisition unit 36 acquires travel information of a vehicle on which the vehicle display device 100 is mounted. Further, the information acquisition unit 36 outputs the travel information to the determination unit 38. The travel information includes a plurality of types of information, and will be specifically described below. The GPS receiving unit 30 measures the current position of the vehicle by receiving a signal from the GPS. The current position is indicated by, for example, latitude and longitude. Since a known technique may be used for positioning the current position, description thereof is omitted here. The GPS receiver 30 outputs current position information to the current position acquisition controller 44. The current position acquisition control unit 44 inputs information on the current position from the GPS receiving unit 30. The current position acquisition control unit 44 outputs current position information to the determination unit 38.

  The navigation data 32 stores map data in advance. Road information is attached to the map data. An example of road information is information related to the width of the road. In addition, facility information is attached to the map data. An example of the facility information is information regarding a parking lot, and position information regarding a parking lot area. Another example of facility information is information relating to a shopping street, and is location information relating to a shopping street area. The navigation information acquisition control unit 42 acquires road information corresponding to the current position from the navigation data 32 based on the current position acquired by the current position acquisition control unit 44. The navigation information acquisition control unit 42 outputs road information corresponding to the current position to the determination unit 38. The navigation information acquisition control unit 42 acquires facility information from the navigation data 32 based on the current position acquired by the current position acquisition control unit 44. The navigation information acquisition control unit 42 outputs facility information corresponding to the current position to the determination unit 38.

  The determination unit 38 inputs the travel information from the information acquisition unit 36, and determines whether or not the situation of the vicinity of the vehicle needs to be determined based on the travel information. Here, three examples of determination in the determination unit 38 will be described.

  (1) The determination unit 38 determines whether or not the vehicle is traveling in the parking lot based on the travel information. Specifically, it is determined whether or not the vehicle is traveling in the parking lot based on the current position information by GPS and the facility information based on the current position information. In addition to outdoor plane parking lots that can receive GPS radio waves, vehicles run in the parking lots even in multi-story parking lots, indoor and underground parking lots due to vehicle acceleration and travel information, or indoor GPS alternative radio waves. Judgment is made. Furthermore, it may be determined that the vehicle is traveling in the parking lot even when the vehicle enters the parking lot or before the predetermined distance (eg, 10 m before) entering the parking lot. The determination part 38 determines with it being "1st condition", if it is not drive | working the inside of a parking lot. On the other hand, if the determination part 38 is drive | working in the parking lot, it will determine with it being a "2nd condition." It can be said that the second situation is a situation requiring judgment of the situation in the vicinity of the vehicle.

  (2) The determination unit 38 determines whether or not the vehicle is traveling on a road having a width less than a predetermined width based on the travel information. The width less than the predetermined is, for example, less than 8 m. The determination unit 38 determines that it is the “first situation” when the vehicle is not traveling on a road having a width less than a predetermined width. On the other hand, the determination unit 38 determines that it is the “second situation” when traveling on a road having a width less than a predetermined width. Again, the second situation can be said to be a situation that requires judgment of the situation in the vicinity of the vehicle.

  (3) The determination unit 38 determines whether or not the vehicle is traveling in the shopping street based on the travel information. In addition to being a shopping street, it may be added on condition that the width of the road is, for example, less than 8 m. The determination unit 38 determines that it is the “first situation” if the vehicle is not traveling in the shopping street. On the other hand, if the determination part 38 is drive | working in a shopping street, it will determine with it being a "2nd condition." Again, the second situation can be said to be a situation that requires judgment of the situation in the vicinity of the vehicle.

  The drive control unit 24 receives the determination result from the determination unit 38. The drive control unit 24 controls the operation of the drive unit 26 according to the determination result. More specifically, when the determination result is “first situation”, the drive control unit 24 controls the drive unit 26 to realize the first display mode. That is, in order to use the first display panel 16, the drive control unit 24 causes the first display panel 16 to face the user and causes the second display panel 18 to face the user. On the other hand, when the determination result is “second situation”, the drive control unit 24 controls the drive unit 26 to realize the second display mode. That is, in order to use the second display panel 18, the drive control unit 24 makes the second display panel 18 face the user and makes the first display panel 16 not face the user. Therefore, when the determination result changes from the “first situation” to the “second situation”, the drive control unit 24 executes the change from the first display form to the second display form. When the state is changed to the “first situation”, the second display form is changed to the first display form.

  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 8A to 8G are used. FIGS. 8A to 8G are side views showing the state of change of the display form by the vehicle display device 100. 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 300, a first shaft 302, a second shaft 304, a rotation drive unit 306, a slide drive unit 308, a slide slide shaft 310, and a display panel storage unit 312. Further, the first display panel 16 and the second display panel 18 are attached to the frame part 300. The rotation driving unit 306 and the slide driving unit 308 correspond to the driving unit 26.

  The display panel storage unit 312 is disposed on the negative direction side of the x axis, that is, on the back side. A slide drive unit 308 is fixed to the positive side of the z-axis of the display panel storage unit 312, that is, the upper surface side. The slide drive unit 308 supports a rod-shaped slide slide shaft 310 extending in the x-axis direction. The slide drive unit 308 includes a motor (not shown) and a pinion gear of the motor, and includes a rack gear (not shown) provided in parallel with the slide slide shaft 310. When the rotational force is applied to the pinion gear by the rotation of the motor of the slide drive unit 308, the rack gear moves in the x-axis direction. Therefore, the slide slide shaft 310 slides in the x-axis direction by driving the slide drive unit 308.

  A frame portion 300 is rotatably attached to the positive end of the x-axis of the slide sliding shaft 310 via the first shaft 302. The first shaft 302 extends in the y-axis direction and is supported by the rotation drive unit 306. The rotation drive unit 306 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 upper 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. A second shaft 304 is provided at the end of the frame 300 opposite to the end where the second display panel 18 is disposed. The second shaft 304 engages and moves with a groove of a slide member provided with a groove along the movement locus of the second shaft 304 inside the side wall of the display panel storage unit 312.

  In FIG. 8B to FIG. 8F, the frame unit 300 rotates around the first shaft 302 when the rotation driving unit 306 is driven. At this time, the slide drive unit 308 may not be driven, and may be driven so as to gradually move the frame unit 300 in the negative direction 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. 8F, 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 lower side. In FIG. 8F to FIG. 8G, the slide slide shaft 310 moves in the negative direction of the x axis when the rotation drive unit 306 is not driven and the slide drive unit 308 is driven. As the slide slide shaft 310 moves, the frame 300 also moves in the negative direction of the x-axis and enters the display panel storage unit 312. FIG. 8G 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. 8G. On the other hand, when the change from the second display mode to the first display mode is executed, the vehicle display device 100 operates in the order from FIG. 8 (g) to FIG. 8 (a).

  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.

  The operation of the vehicle display device 100 having the above configuration will be described. FIG. 9 is a flowchart showing a procedure for changing the display form by the vehicle display device 100. The information acquisition unit 36 acquires vehicle travel information (S10). If it is a situation that requires continuous judgment of the situation in the vicinity of the vehicle (Y in S12), the changing unit 10 changes to the second display mode (S14). If the situation in the vicinity of the vehicle is not continuously required (N in S12) and the display mode is the second display mode (Y in S16), the changing unit 10 changes to the first display mode (S18). If it is not the second display mode (N in S16), step 18 is skipped.

  According to the embodiment of the present invention, when the situation in the vicinity of the vehicle needs to be judged, the change from the first display form to the second display form is executed, so that the field of view immediately before the front is secured according to the driving situation. it can. In addition, since the first display panel is used as the first display form and the second display panel is used as the second display form, the two display forms can be reliably changed. Further, since the display area of the second display panel is made smaller than the display area of the first display panel, two types of display areas with different visibility can be realized. Further, since the second display panel displays at least the traveling speed of the vehicle, it is possible to provide necessary indispensable information even when the display area is small.

  In addition, since the change from the first display form to the second display form is executed when traveling in a parking lot, it is possible to easily confirm information even in a situation that requires situation determination in the vicinity of the vehicle. . In addition, since the change from the first display form to the second display form is executed when traveling on a road with a width less than a predetermined width, it is possible to easily confirm information even in a situation that requires a situation determination in the vicinity of the vehicle. be able to. In addition, when traveling in a shopping street, the change from the first display form to the second display form is executed, so that it is possible to easily confirm information even in a situation that requires a situation determination near the vehicle. it can.

(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. Also in the second embodiment, the vehicular display device causes one of the first display panel and the second display panel to face the user in accordance with the traveling state of the vehicle and the like. In Example 1, two display panels having different display areas are provided in order to realize the first display mode and the second display mode. On the other hand, in the second embodiment, only one display panel is provided, and the first display form and the second display form are realized by changing the exposed area of the display panel. Therefore, in the second embodiment, the first display form is a display form with a large display area, and the second display form is a display form with a small display area. Here, it demonstrates centering on the difference with Example 1. FIG.

  FIGS. 10A to 10B are side views showing the configuration of the vehicle display device 100 according to the second embodiment of the present invention. FIG. 10A is a side view of the vehicle display device 100 in the first display mode. The vehicle display device 100 includes a display panel 500, a frame part 502, a slide drive part 504, and a cover part 506. A display panel 500 is attached to the frame portion 502. The display panel 500 corresponds to the first display panel 16 and the second display panel 18 so far, and particularly corresponds to the first display panel 16 in FIG. The display panel 500 is an LCD or the like, and is composed of, for example, a TFT liquid crystal and has an instrument panel function, and displays information used for driving the vehicle. FIGS. 11A to 11B show screens displayed on the display panel 500. FIG. FIG. 11A shows a screen in the case of the first display form, which corresponds to the image for the first display form described above. This is the same as FIG. FIG. 11B will be described later, and the processing returns to FIG.

  The slide drive unit 504 corresponds to the drive unit 26 described above. The slide drive unit 504 is fixed to the front side of the dashboard 204 and supports the frame unit 502. The slide drive unit 504 includes a motor (not shown) and a pinion gear of the motor, and the side surface of the frame unit 502 includes a rack gear extending in the z-axis direction. When a rotational force is applied to the pinion gear by the rotation of the motor of the slide drive unit 504, the rack gear moves in the z-axis direction. Therefore, the frame unit 502 slides in the z-axis direction by driving the slide drive unit 504.

  A cover portion 506 is provided on the front side of the dashboard 204 and on the negative side of the z-axis of the frame portion 502. The cover unit 506 may be configured integrally with the dashboard 204 or may be configured separately from the dashboard 204. In addition, a hole portion through which the frame portion 502 can enter is provided on the upper surface side of the cover portion 506.

  FIG. 10B is a side view of the vehicle display device 100 in the second display mode. In FIG. 10A to FIG. 10B, the frame drive unit 504 is driven to move the frame unit 502 in the negative direction of the z axis. By this movement, a part of the negative side of the z-axis of the frame part 502 enters the cover part 506. In FIG. 10B, the exposed portion of the display panel 500 that is on the positive side of the z-axis is indicated as a first display area 508. A portion on the negative direction side of the z axis and stored in the cover portion 506 is indicated as a second display area 510. Here, the first display area 508 corresponds to the second display panel 18. That is, the drive control unit 24 (not shown) exposes the entire display panel 500 as the first display form, and exposes the first display region 508 that is a part of the display panel 500 as the second display form. As described above, the display area of the first display region 508 is smaller than the display area of the display panel 500.

  FIG. 11B is a screen in the case of the second display form, and corresponds to the above-described image for the second display form. This is the same as FIG. As described above, the information amount of information displayed on the second display form image is smaller than the information amount of information displayed on the first display form image. Further, the second display form image generated by the display control unit 28 may include a shift change indicator, and it is sufficient that at least the traveling speed of the vehicle is included.

  According to the embodiment of the present invention, the display panel is exposed as the first display form, and a part of the display panel is exposed as the second display form. Therefore, the first display form and the second display form can be combined with one display panel. realizable. Moreover, since the first display mode and the second display mode are realized by one display panel, an increase in cost can be suppressed. Moreover, since the display area of the first display area is smaller than the display area of the display panel, two types of display areas with different visibility can be realized. Further, since the first display area displays at least the traveling speed of the vehicle, it is possible to provide necessary indispensable information even when the display area is small.

  In the above, this invention was demonstrated based on the Example.
