Description

  The present invention relates to a vehicle display device mounted on a vehicle.

  Conventionally, for example, Patent Literature 1 discloses a vehicle display device that displays information on a half mirror disposed in an instrument panel and a combiner installed on a front windshield. In this vehicle display device, the half mirror and the combiner function as display areas for displaying information. Therefore, the amount of information that can be provided to the viewer can be increased.

JP 2006-103589 A

  Now, in the form of displaying information in a plurality of display areas as in the vehicle display device of Patent Document 1, various information can be displayed simultaneously. Therefore, the viewer cannot find the desired information at first glance, but seeks the desired information and makes his gaze look. As a result, the movement of the line of sight from the foreground of the vehicle to the half mirror and the combiner and the movement of the line of sight between the half mirror and the combiner are repeated, and the load of the line of sight movement of the viewer can be very large.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a vehicle display device that can reduce the load of visual line movement of a viewer while ensuring the amount of information that can be provided to the viewer. Is to provide.

  In order to achieve the above object, a first invention is a vehicle display device mounted on a vehicle, the display means (13) displaying an image (32) in the first display area (11), and the vehicle Projecting means (60) for displaying a virtual image (35) of the display image on the second display area by projecting the display image onto the second display area (111) defined by the projection unit (110) that transmits the foreground of ), And the first display part (32a, 32c, 32d) rendered in the first display area and the second display part (35c, 35h, 35t, 35j) projected in the second display area, It is characterized by displaying information related to each other, and an information amount of information displayed on the second display unit is smaller than an information amount of information displayed on the first display unit.

  In this invention, since the information display of the 1st display part of a 1st display area and the 2nd display part of a 2nd display area is mutually related, the 2nd display part with less information amount than a 1st display part is provided. Even if it is visually recognized, the outline of information displayed on the two display units can be grasped. For this reason, the viewer's line of sight is first directed to the second display unit having a small amount of information among the two display units. In this way, the viewer's line of sight is first directed to the second display unit displayed as a virtual image, so that acquisition of desired information can be completed by a small line of sight movement from the foreground to the virtual image under many circumstances.

  In addition, only when the desired information cannot be obtained from the second display unit, the viewer only needs to look at the first display unit that displays detailed information as necessary. For this reason, implementation of line-of-sight movement with a heavy load from the foreground to the first display area can be limited to a few situations that require detailed information. Therefore, the vehicular display device can reduce the load of the viewer's line of sight movement while securing the amount of information that can be provided to the viewer.

The liquid crystal display 13 has a plurality of pixels arranged two-dimensionally along the display screen 12. The liquid crystal display 13 is connected to the control unit 20 and drives each pixel based on a control signal output from the control unit 20. Various images that are displayed in color in the multi-display area 11 are formed on the display screen 12 of the liquid crystal display 13. The backlight 14 illuminates the image on the display screen 12 with a light source such as a plurality of light emitting diodes (hereinafter referred to as LEDs). The backlight 14 is connected to the control unit 20, and the luminance of the illumination is controlled by a control signal output from the control unit 20.

  The stepper motor 17 is an electric motor that drives the hands 16. The stepper motor 17 is connected to the control unit 20, and forms a pointer display in the pointer display region 15 by rotating the pointer 16 based on a control signal output from the control unit 20. The indicator light source 19 is, for example, an LED. Each indicator light source 19 is connected to the control unit 20 and emits light for causing each indicator 18 to emit light based on a control signal output from the control unit 20.

  The control unit 20 includes a microcomputer that operates according to a program, an interface that communicates with an in-car local area network (LAN) 140, and a drive circuit that drives the liquid crystal display 13, the stepper motor 17, each light source, and the like. It is configured. In addition to a plurality of in-vehicle devices 150 mounted on the vehicle, a steering switch 130 and the like are connected to the in-vehicle LAN 140. The control unit 20 acquires vehicle information output to the in-vehicle LAN 140, and outputs a control signal based on the acquired information to the liquid crystal display 13, the stepper motor 17, and each light source.

  The projector 61 of the HUD 60 has a liquid crystal display 62 and a projection light source 63. The liquid crystal display 62 is a TFT display, for example. The liquid crystal display 62 is connected to the control unit 20 and drives each pixel based on a control signal output from the control unit 20. Various images that are displayed in color in the virtual image display area 111 (see FIG. 1) are formed on the liquid crystal display 62. The projection light source 63 has, for example, a plurality of high-brightness LEDs. The projection light source 63 is connected to the control unit 20, and emits light formed as a virtual image 35 (see FIG. 1) toward the liquid crystal display 62 based on a control signal output from the control unit 20. .

  In the display device 100 described above, the display modes of the two display areas 11 and 111 arranged vertically in the appearance of the viewer can be switched among a plurality of display modes. Such a display mode switching operation can be performed by an input to the steering switch 130 provided in the steering of the vehicle. Hereinafter, the configuration of each display in the multi display area 11 and the virtual image display area 111 in each display mode will be described in order based on FIGS. 4 to 7.

  FIG. 4 shows each display of the display areas 11 and 111 in the fuel consumption display mode. In the fuel consumption display mode, the fuel consumption graph 32a drawn in the multi display area 11 and the instantaneous fuel consumption meter 35c displayed in the virtual image display area 111 display information related to each other. The amount of information displayed on the instantaneous fuel consumption meter 35c is smaller than the amount of information displayed on the fuel consumption graph 32a. Details will be described below.

  The image 32 drawn in the multi display area 11 includes a vehicle model 42 and a background image 32f in addition to the fuel consumption graph 32a described above. The fuel consumption graph 32a displays vehicle information output from the in-vehicle device 150 (see FIG. 3), specifically, past history values of the fuel consumption information. The fuel consumption graph 32a has a plurality of bar elements 32b extending in a strip shape along the width direction WD. The length of each bar element 32b corresponds to the fuel consumption of the vehicle every predetermined time. The plurality of bar elements 32b are arranged in the downward direction DD from the upper edge of the multi display area 11, and move in the downward direction DD with the passage of time. Therefore, the bar element 32b indicating new fuel efficiency information is positioned in the upward direction UD. With such a bar graph-like display, the fuel consumption graph 32a shows a change in fuel consumption every predetermined time.

  The vehicle model 42 is created by imitating the external shape of a vehicle on which the display device 100 (see FIG. 1) is mounted. In the multi-display area 11, an image obtained by bird's-eye view of the vehicle model 42 from behind is displayed. The front-rear direction of the vehicle model 42 is defined along the front-rear direction of the actual vehicle. The vehicle model 42 is arranged in the center of the multi display area 11 and is superimposed on the fuel consumption graph 32a and the background image 32f.

  The background image 32 f is an image that becomes the background of the fuel consumption graph 32 a and the vehicle model 42 in the multi-display area 11. The background image 32f has a road surface image portion 32w extending in a strip shape along the vertical direction. The road surface image portion 32w is an image portion that imitates a roadway on which the vehicle model 42 travels. A pair of boundary lines 32r is formed on both sides of the road surface image portion 32w in the width direction WD, and the vehicle model 42 is disposed between these two boundary lines 32r.

  The virtual image 35 displayed in the virtual image display area 111 includes a shift indicator 35a and a digital speedometer 35b in addition to the above instantaneous fuel consumption meter 35c. The shift indicator 35a indicates the current position of the shift lever provided in the vehicle. The digital speedometer 35b indicates the current traveling speed of the vehicle. The digital speedometer 35b is arranged with the shift indicator 35a in the width direction WD.

  The instantaneous fuel consumption meter 35c displays the latest value of the fuel consumption information currently acquired by the control unit 20 (see FIG. 3). The instantaneous fuel consumption meter 35c has a bar element 35g substantially the same as the bar element 32b of the fuel consumption graph 32a. The bar element 35g expands and contracts in the width direction WD corresponding to the latest fuel efficiency of the vehicle, and becomes longer in the width direction WD as the fuel efficiency is improved. As a predetermined time elapses, the bar element 35g displayed on the instantaneous fuel consumption meter 35c moves to the multi-display area 11 and is used as one of the plurality of bar elements 32b forming the fuel consumption graph 32a. Is displayed in the uppermost direction UD.

  5 and 6 show each display of the display areas 11 and 111 in the eco display mode. In the eco display mode, the eco gauge 32 c drawn in the multi display area 11, the eco indicator 35 h and the item display 35 t displayed in the virtual image display area 111 display information related to each other. In addition, the information amount of information displayed on each of the eco indicator 35h and the item display 35t is smaller than the information amount of information displayed on the eco gauge 32c. Details will be described below.

  The image 32 drawn in the multi-display area 11 includes a vehicle model 42 and a background image 32f that are substantially the same as those in the fuel consumption display mode, in addition to the above-described eco gauge 32c. The eco gauge 32c displays the vehicle information output from the in-vehicle device 150 (see FIG. 3), specifically, the degree of fuel efficiency in an analog manner. The fuel efficiency is calculated by the control unit 20 (see FIG. 3) or any one of the in-vehicle devices 150 based on the amount of fuel consumed by a traveling engine mounted on the vehicle, the speed and acceleration of the vehicle, and the like. The eco-gauge 32c visualizes the state of eco-driving with a bar-shaped image portion extending around the vehicle model 42 in an annular shape. The better the fuel efficiency, the more the eco gauge 32c extends counterclockwise toward the left rear of the vehicle model 42.

  The virtual image 35 displayed in the virtual image display area 111 includes the above-described eco-indicator 35h and item display 35t in addition to the shift indicator 35a and the digital speedometer 35b that are substantially the same as those in the fuel consumption display mode.

  The eco indicator 35h is displayed in the virtual image display area 111 when the fuel efficiency currently acquired by the control unit 20 (see FIG. 3) or currently calculated satisfies a predetermined condition. The eco indicator 35h is a display image imitating characters such as “ECO”, for example. The eco indicator 35h is arranged, for example, in the lower right corner of the virtual image display area 111 so as to line up with the item display 35t and the width direction WD. When the fuel efficiency is lower than the predetermined threshold, when the eco gauge 32c is lower than the predetermined threshold, the display of the eco indicator 35h is interrupted as shown in FIG.

  The item display 35t shown in FIG.5 and FIG.6 has shown the item currently displayed on the multi display area 11 with the character. In the eco display mode, the characters “ECO Bar” are displayed as the vehicle information displayed on the eco gauge 32c, that is, the item name serving as a headline of fuel efficiency. The item display 35t is arranged in the downward direction DD of the digital speedometer 35b in the virtual image display area 111. The characters displayed as the item display 35t are switched in accordance with the change of the vehicle information displayed in the multi display area 11.

  FIG. 7 shows each display in the display areas 11 and 111 in the supercharging pressure display mode. In the supercharging pressure display mode, the boost gauge 32d drawn in the multi-display area 11 and the digital boost meter 35j displayed in the virtual image display area 111 display information related to each other.

  In addition to the boost gauge 32d described above, the image 32 drawn in the multi-display area 11 includes a vehicle model 42 and a background image 32f that are substantially the same as in the fuel consumption display mode. The boost gauge 32d displays in analog form the vehicle information output from the in-vehicle device 150 (see FIG. 3), specifically, the degree of gauge pressure in the intake pipe of the traveling engine. The boost gauge 32d visualizes the pressure in the intake pipe by a bar-shaped image portion extending in an annular shape around the vehicle model. When the pressure in the intake pipe is on the positive pressure side higher than the atmospheric pressure, the boost gauge 32d extends clockwise from the zero point position toward the right rear of the vehicle model 42 as the gauge pressure increases. When the pressure in the intake pipe is on the negative pressure side lower than the atmospheric pressure, the boost gauge 32d extends counterclockwise from the zero point position toward the left rear of the vehicle model 42 as the gauge pressure decreases.

  The virtual image 35 displayed in the virtual image display area 111 includes the above-described digital boost meter 35j in addition to the shift indicator 35a and the digital speedometer 35b which are substantially the same as those in the fuel consumption display mode. The digital boost meter 35j digitally displays the same vehicle information as the boost gauge 32d, that is, the gauge pressure in the intake pipe by numerical values. The digital boost meter 35j is disposed at the center in the width direction WD of the virtual image display area 111, and is positioned in the downward direction DD of the shift indicator 35a and the digital speedometer 35b.

  The analog display by the boost gauge 32d described above can indicate the change range of the gauge pressure in the intake pipe together with the current value of the supercharging pressure. On the other hand, the digital display by the digital boost meter 35j merely indicates the current value of the supercharging pressure. Thus, the information amount of information displayed on the digital boost meter 35j is smaller than the information amount of information displayed on the boost gauge 32d.

  In each display mode of the present embodiment described so far, the information display by the multi display area 11 and the information display of the virtual image display area 111 are related to each other. Therefore, even if the display of the virtual image display area 111 with a small amount of information is visually recognized, an outline of information displayed in the two display areas 11 and 111 can be grasped. Therefore, the viewer's line of sight first comes to the instantaneous fuel consumption meter 35c or the like in the virtual image display area 111 that is easily grasped by reducing the amount of information. Thus, according to the fact that the viewer's line of sight is first directed to the instantaneous fuel consumption meter 35c or the like displayed as the virtual image 35, acquisition of desired information can be achieved by a small line of sight movement from the foreground to the virtual image 35 in many situations. Can be done.

  In addition, only when the desired information cannot be obtained from the display of the virtual image display area 111, the viewer only needs to look at the display of the multi-display area 11 that displays detailed information as necessary. . For this reason, implementation of line-of-sight movement with a large load from the foreground to the virtual image display area 111 can be limited to a few situations that require detailed information. Therefore, the display device 100 can reduce the load of eye movement of the viewer while ensuring the amount of information that can be provided to the viewer.

  In the fuel consumption display mode of the present embodiment, the latest fuel consumption information that the viewer wants to check is displayed in the virtual image display area 111 by the instantaneous fuel consumption meter 35c. Therefore, the viewer can acquire the fuel consumption information by moving the line of sight to the virtual image 35 little. The past fuel consumption information can be confirmed by moving the line of sight to the fuel consumption graph 32a as necessary. As described above, the display device 100 moves the viewer's line of sight while ensuring the amount of information that can be provided by allocating the latest value and the history value of the fuel efficiency information to the instantaneous fuel efficiency meter 35c and the fuel efficiency graph 32a. Can reduce the load.

  In addition, in the eco display mode of the present embodiment, the eco indicator 35h is displayed in the virtual image display area 111 when the fuel efficiency displayed on the eco gauge 32c is good. Although this eco-indicator 35h cannot indicate the current level of fuel efficiency in detail, if an appropriate condition is set for the threshold, the eco-indicator 35h can simply notify the viewer of the current fuel efficiency. According to the above, since the current fuel efficiency can be confirmed by turning the line of sight toward the eco-indicator 35h, it is possible to reduce the load of the viewer's line-of-sight movement.

  Furthermore, in the eco display mode of the present embodiment, the item name that is the heading of the vehicle information displayed on the eco gauge 32c is displayed on the item display 35t. Therefore, the viewer can grasp the contents currently displayed in the multi-display area 11 by directing his / her line of sight to the item display 35t. According to the above, after viewing the item display 35t, the viewer determines whether or not there is desired information in the multi-display area 11, and if not, stops the line-of-sight movement to the eco gauge 32c or the like. be able to. According to the above, since unnecessary line-of-sight movement from the foreground to the multi-display area 11 can be avoided, the load of the line-of-sight movement of the viewer can be surely reduced.

  Further, as in the supercharging pressure display mode of the present embodiment, the display of the digital boost meter 35j succinctly shows the gauge pressure numerically, so that it is possible to grasp information in a shorter time than the analog display by the boost gauge 32d. To do. Therefore, the visual line of the viewer is easily directed to the digital boost meter 35j that can quickly perceive the gauge pressure. As described above, in the configuration in which the vehicle information is digitally displayed by the virtual image 35, the load of eye movement can be reduced. In addition, since the analog display coexists with the digital display, the amount of information provided to the viewer is also ensured.

  If the multi-display area 11 and the virtual image display area 111 are arranged in the same circular line in a vertical relationship as in the present embodiment, the viewer can instantaneously consume fuel without moving the head left and right. The line of sight can be shifted from the total 35c or the like to the fuel consumption graph 32a or the like. Therefore, it is possible to reduce the load on the line of sight movement between the two display areas 11 and 111.

  In the present embodiment, the multi-display area 11 corresponds to the “first display area” described in the claims, the liquid crystal display 13 corresponds to the “display means” described in the claims, and the HUD 60 Corresponds to “projection means” recited in the claims. The display device 100 corresponds to the “vehicle display device” recited in the claims, the virtual image display region 111 corresponds to the “second display region” recited in the claims, and the windshield 110 is patented. This corresponds to the “projection unit” recited in the claims. Further, the fuel consumption graph 32a, the eco gauge 32c, and the boost gauge 32d correspond to the “first display portion” recited in the claims. The instantaneous fuel consumption meter 35c, the eco indicator 35h, the digital boost meter 35j, and the item display 35t correspond to the “second display portion” recited in the claims.

(Other embodiments)
As mentioned above, although one embodiment by the present invention was described, the present invention is not interpreted limited to the above-mentioned embodiment, and is applied to various embodiments and combinations within the range which does not deviate from the gist of the present invention. be able to.

  In the fuel consumption display mode of the above embodiment, the latest value of fuel consumption information and the past history value are allocated and displayed in the instantaneous fuel consumption meter 35c and the fuel consumption graph 32a, respectively. Thus, the vehicle information in which the latest value and the history value are displayed together is not limited to the fuel efficiency information described above. For example, the traveling speed information of the vehicle, the atmospheric pressure information outside the vehicle, the temperature information, and the like can be allocated to the latest value and the history value and displayed in two display areas in parallel.

  In the eco display mode of the above embodiment, the eco indicator 35h is turned on when the level of fuel efficiency is displayed by the eco gauge 32c and exceeds a predetermined fuel efficiency. Thus, the vehicle information in which the detailed contents and the summary are displayed in parallel is not limited to the fuel efficiency described above. For example, the fuel supply indicator may be lit in the virtual image display area 111 when the amount of fuel remaining in the fuel tank is displayed in the multi-display area 11 by the first display unit and falls below a predetermined remaining amount.

  In the eco display mode of the above embodiment, the eco indicator 35h and the item display 35t correspond to the second display unit, respectively. However, an eco display mode for displaying only one of these may be set in the display device. Furthermore, in the display mode in which a plurality of first display units indicating different vehicle information are displayed in the multi display area, a plurality of item displays may be displayed side by side in the virtual image display area.

  In the supercharging pressure display mode of the above embodiment, an analog display indicating the degree of gauge pressure and a digital display coexist. Thus, the vehicle information shown simultaneously by the analog display and the digital display is not limited to the supercharging pressure. For example, in a display device in which the entire surface of the combination meter has a multi-display area, the traveling speed information of the vehicle may be digitally displayed in the virtual image display area and analog-displayed in the multi-display area by a pointer image.

  In addition, the amount of information displayed on each of the first display unit and the second display unit may be changed according to the driving state of the vehicle. For example, the information amount of information displayed on each of the first display unit and the second display unit when the vehicle is stopped may be relatively increased as compared with the traveling state of the vehicle. Specifically, when the vehicle is stopped, a large-scale detailed map for destination guidance by the navigation system is displayed on the first display unit, and displayed on the first display unit on the second display unit. A map of destination guidance with a medium scale or a small scale rather than a map is displayed. When the vehicle travels, a large-scale detailed map for destination guidance displayed on the first display unit is maintained, and a turn-by-turn arrow is displayed on the second display unit instead of the map display. May be displayed.

  In the multi display area and the virtual image display area in the above embodiment, the center positions in the vehicle width direction WD are aligned with each other. However, the position of each display area is not limited to the arrangement of the above embodiment, and can be changed as appropriate. For example, the virtual image display area may be defined near the center in the width direction WD of the windshield. Or the combination meter which forms a multi display area may be accommodated near the center of the width direction WD of the instrument panel.

  In the above embodiment, the display mode can be switched by operating the steering switch. However, the configuration in which an operation for changing the display mode is input is not limited to the steering switch, and may be, for example, a joystick provided on the center console, a touch panel, or the like.

  In the above embodiment, the vehicle windshield is used as the “projection unit” on which the display image is projected. However, the “projection unit” is not limited to the windshield. For example, a combiner that is formed in a plate shape with a translucent resin and attached to the upper surface of the instrument panel or the vehicle interior side of the windshield may be installed as a configuration corresponding to the “projection unit”.

  The projector according to the embodiment has a configuration in which a TFT liquid crystal display and a projection light source are combined. However, the configuration for projecting the display image can be changed as appropriate. For example, a liquid crystal display other than the TFT method can be used. Furthermore, a display image may be projected by a DLP (Digital Light Processing: registered trademark) projector, a CRT projector, or the like. Furthermore, a laser scanner using MEMS (Micro Electro Mechanical Systems) may be included in the “projection unit” as a configuration for projecting a display image.

  In the above embodiment, the function provided by the control unit 20 that has executed the program may be provided by hardware and software different from the above-described configuration, or a combination thereof.
