  Next, the configuration of each display formed in the multi display area 11, the virtual image display area 111, and the pointer display area 15 will be described in more detail with reference to FIG. The display device 100 (see FIG. 3) can switch the display mode among a plurality of display modes. Such a display mode switching operation is performed by an input to a steering switch 130 (see FIG. 3) provided in the steering of the vehicle. In the following description, each display configuration in one typical display mode is shown.

  The image 32 drawn in the multi-display area 11 includes an eco gauge 32c, a vehicle model 42, a background image 32f, an eco wallet 32g, a fuel gauge 32h, and an odometer 32i. In this way, vehicle information that is more detailed than the virtual image display area 111 is displayed in the multi-display area 11. In addition, in order to display a large amount of vehicle information, the area of the multi display area 11 is made larger than the area of the virtual image display area 111.

  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 implementation state of eco driving by a bar-shaped image portion extending in a partial annular shape around the vehicle model. The better the fuel efficiency, the more the eco gauge 32c extends counterclockwise toward the left rear of the vehicle model 42.

  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.

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 eco wallet 32g shows the fuel cost saved by the implementation of the eco driving by the amount. The fuel meter 32h indicates the remaining amount of fuel in the fuel tank. The odometer 32i indicates a cumulative value of the travel distance of the vehicle.

  The virtual image 35 displayed in the virtual image display area 111 includes a shift indicator 35a, a digital speedometer 35b, an item display 35t, and a confirmation notification frame 35e. 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 item display 35t indicates the items displayed in the multi display area 11 by characters. 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.

  The confirmation notification frame 35e is imaged on the outer peripheral side of the shift indicator 35a, the digital speedometer 35b, and the like when viewed from the viewer. The confirmation notification frame 35e has a discontinuous frame shape surrounding other display images by L-shaped display images arranged at the four corners of the virtual image display area 111. The confirmation notification frame 35e is lit for about 1 second, for example, when a pressing operation is input to the enter key 132 (see FIG. 3). The lighting time of the confirmation notification frame 35e can be changed as appropriate.

  A shift indicator 39a and an analog speedometer 39b are formed on one of the two pointer display areas 15 located on the left side of the multi-display area 11. A tachometer 39c is formed in the pointer display area 15 located on the right side of the multi display area 11.

  The shift indicator 39a indicates the current position of the shift lever, similarly to the shift indicator 35a in the virtual image display area 111. The analog speedometer 39b is formed by the hands 16 arranged in the left hand pointer display area 15, and scales and numerical values arranged along the rotation trajectory of the hands 16. The analog speedometer 39b indicates the traveling speed of the vehicle by the rotational displacement of the pointer 16. The tachometer 39c is formed by a pointer 16 arranged in the pointer display area 15 on the right side, and scales and numerical values arranged along the rotation trajectory of the pointer 16. The tachometer 39 c indicates the rotational speed of the output shaft of the traveling engine due to the rotational displacement of the pointer 16.

  In the display device 100 described above, when information is displayed by the virtual image 35 in the virtual image display area 111, the display of information by the pointer display area 15 is interrupted. FIGS. 5A to 5C show a display changing process when the display of the pointer display area 15 is turned off in conjunction with the operation of the viewer who turns the display of the virtual image display area 111 on. Yes. Hereinafter, the details of the changing process will be described in order.

  When the viewer turns on the display of the virtual image display area 111 by operating the steering switch 130 (see FIG. 3), the light emitting spot 38 is displayed on the two linear light emitting units 81 as shown in FIG. 5A. In addition, a reflection image 36 of the light emission spot 38 is displayed in the reflection display area 112.

  As shown in FIGS. 5A and 5B, each light emission spot 38 moves in the upward direction UD toward the virtual image display region 111 in the appearance of the viewer. On the other hand, each reflected image 36 moves downward DD toward the virtual image display area 111. The movement of the light-emitting spot 38 and the reflected image 36 is perceived by the viewer as a linkage line that is displayed in a linear manner. Each light emitting spot 38 disappears by reaching the end of the light emitting surface 81 a close to the virtual image display area 111.

  When the light emission of each linear light emitting unit 81 is completed, as shown in FIG. 5B, a shift indicator 35a, a digital speedometer 35b, and an item display 35t are displayed in the virtual image display area 111. When the display reflecting the operation of the viewer is completed in the virtual image display area 111, the confirmation notification frame 35e is temporarily turned on.

  When the position information of the shift lever (hereinafter referred to as “shift position information”) and the traveling speed information of the vehicle (hereinafter referred to as “vehicle speed information”) can be grasped also from the virtual image display area 111, as shown in FIG. Information display is interrupted. At this time, first, the pointers 16 and the scales and numerical values are turned off by stopping the light emission of the pointer light source 16a (see FIG. 3) and the dial light source 16b (see FIG. 3). Next, the return of each pointer 16 to the preset zero position P0 is started. As described above, the display of the vehicle information is collected in the multi-display area 11 and the virtual image display area 111 arranged vertically.

  In order to realize the display layout change described above, a change process performed by the control unit 20 will be described based on FIG. 6 with reference to FIG. The change process shown in FIG. 6 is started by the control unit 20 based on an operation that turns on the display of the virtual image display area 111 into the steering switch 130 or the like.

  In S101, a light emission process for causing the light emitting unit 80 to emit light is started, and the process proceeds to S102. By the processing of S101, the light emission spot 38 and the reflection image 36 thereof are displayed and flow toward the virtual image display area 111 (see FIGS. 5A and 5B).

  In S102, an activation process for activating the projector 61 is started so that the virtual image 35 is displayed in the virtual image display area 111, and the process proceeds to S103. Through the process of S102, the shift indicator 35a and the like are displayed in the virtual image display area 111 (see FIG. 5B).

  In S103, it is determined whether or not the activation process started in S102 is completed. If a negative determination is made in S103, the determination in S103 is repeated to wait for the completion of the activation process. When the startup process is completed and an affirmative determination is made in S103, the process proceeds to S104.

  In S104, the lighting process of the confirmation notification frame 35e is performed, and the process proceeds to S105. By the process of S104, the confirmation notification frame 35e is temporarily displayed in the virtual image display area 111, and confirmation of the display layout of the virtual image display area 111 is notified to the viewer (see FIG. 5B).

  In S105, the pointer light source 16a and the dial light source 16b are turned off, and the process proceeds to S106. By S105, the display of information by the two pointer display areas 15 becomes invisible to the viewer. In step S106, each stepper motor 17 is controlled so that each pointer 16 returns to its zero position P0, and the change process ends. As a result, the display of information by the two pointer display areas 15 is turned off (see FIG. 5C).

  In the present embodiment described so far, detailed vehicle information such as the eco gauge 32 c and the odometer is displayed in the multi display area 11. Therefore, the virtual image 35 is a display that briefly notifies the shift position information, the vehicle speed information, and the like. As a result, it is possible to avoid a situation in which the viewer (driver) is prevented from concentrating on driving due to the complex display form of the virtual image 35 that is easily visible.

  In addition, when the pointer display in the pointer display area 15 is interrupted, the information display by the display device 100 is collected in two display areas 11 and 111 arranged vertically. Therefore, the driver can grasp detailed information from the display of the multi-display area 11 by a simple operation of moving the line of sight in the vertical direction. Therefore, even when an operation for acquiring detailed information is performed, concentration on driving is easily maintained.

  Therefore, even if the amount of information that can be provided to the driver is secured, the display by the display device 100 is a display that is difficult to prevent the driver from concentrating on driving.

  In addition, in this embodiment, after each vehicle information provided by the shift indicator 39a and the analog speedometer 39b is also provided from the shift indicator 35a and the digital speedometer 35b, The display is interrupted. Thus, if the vehicle information presented by the pointer display area 15 is moved to the virtual image display area 111, a decrease in the amount of information that can be provided due to the interruption of the pointer display can be suppressed.

  Further, as in the present embodiment, the pointer display area 15 for displaying the pointer has a large area with respect to the amount of information that can be notified and is easily noticeable. When the display of such a conspicuous pointer display area 15 disappears in appearance, the driver's line of sight seems to face naturally to the multi-display area 11 that displays a large amount of information in a small area. become. Therefore, detailed information grasping from the combination meter 10 becomes easier. In addition, the reduction in the amount of information that can be provided due to the interruption of the pointer display can be easily compensated by other display areas. Therefore, the pointer display area 15 is preferable to the multi-display area 11 as the display area where the display is interrupted.

  Further, in this embodiment, the return of the pointer 16 is performed after the pointer light source 16a and the dial light source 16b are turned off. According to such control, it is difficult for the driver to perceive the operation of returning the pointer 16 to zero. Therefore, a situation in which the driver who has visually recognized the pointer 16 in the middle of return zero reads an incorrect pointer display is avoided.

  In addition, the display of information in the multi display area 11 of the present embodiment is performed by the liquid crystal display 13. With such a configuration, the multi-display area 11 can display a large amount of information in a small area. As a result, even if a lot of detailed information is displayed, the driver can quickly grasp the desired detailed information without causing a gaze in the multi display area 11.

  Further, according to the present embodiment, since the area of the multi-display area 11 is secured wider than the area of the virtual image display area 111, a large amount of information can be collected in the multi-display area 11. Therefore, the virtual image 35 in the virtual image display area 111 can be displayed more simply. By using such a simple virtual image display, it is possible to create a driving environment in which the driver's concentration on driving is further prevented.

  Furthermore, in this embodiment, since the display by the two pointer display areas 15 having a large display area is interrupted, most of the front side of the combination meter 10 is in a state where no information is displayed. As a result, the central multi-display area 11 becomes more prominent, so that the driver's line of sight is easily guided to the multi-display area 11. According to the above, since detailed information grasping from the multi-display area 11 is further facilitated, the driver can reliably maintain concentration on driving even when performing an operation of acquiring detailed information. it can.

  In this embodiment, the combination meter 10 corresponds to “display means” described in the claims, the multi-display area 11 corresponds to “first display area” described in the claims, and the liquid crystal display. The device 13 corresponds to a “display device” described in the claims. The pointer display area 15 corresponds to the “second display area” described in the claims, the control unit 20 corresponds to the “display control means” described in the claims, and the HUD 60 corresponds to the claims. The “projection means” described in the above. Further, the display device 100 corresponds to a “vehicle display device” described in the claims, and the windshield 110 corresponds to a “projection unit” described in the claims.

Specifically, the virtual image display area 311 is defined at a position near the center of the windshield 110 in the width direction WD from the front of the driver's seat. The multi display area 211 is formed in the area from the center to the right side (passenger seat side) in front of the combination meter 210, and is positioned in the downward direction DD of the virtual image display area 311 in terms of the driver's appearance. The pointer display area 215 is located on the left side of the multi display area 211.

  Even in the first modification, when information is displayed by the virtual image 35 in the virtual image display area 311, the display of information by the pointer display area 215 is interrupted. Specifically, the pointer 16 returns to the zero position P0, and the displays such as the shift indicator 39a and the water temperature gauge 39d are turned off. On the other hand, the display of the detailed information by the multi display area 211 is continued even when the information display by the virtual image display area 311 is performed. At this time, more vehicle information than the virtual image display area 311 is displayed in detail in the multi display area 211.

  As in Modification 1 above, as long as the virtual image display area 311 and the multi-display area 211 partially overlap in the vertical direction, their center positions may be shifted in the width direction WD. In addition, the pointer display area 215 may be formed only on one side of the multi display area 211. Alternatively, a plurality of pointer display areas may be formed on one side of the multi display area. In the first modification, the combination meter 210 corresponds to the “display means” described in the claims, the multi-display area 211 corresponds to the “first display area” described in the claims, and the pointer display The region 215 corresponds to a “second display region” described in the claims.

  In the above embodiment, the display of the pointer display area is interrupted among the multi-display area and the pointer display area. However, the display of the pointer display area arranged in the lower direction DD of the virtual image display area may be continued, and the display of the multi display area arranged on the side of the pointer display area may be interrupted. Or display of a specific pointer display area may be continued among a plurality of pointer display areas, and display of other pointer display areas may be interrupted.

  In the above embodiment, before the display of the pointer display area is interrupted, the shift indicator and the speedometer are moved from the pointer display area to the virtual image display area. Thus, the movement destination for moving the information display in the pointer display area may not be the virtual image display area, but may be a multi-display area.

  In the above embodiment, the multi display area is defined wider than the virtual image display area. However, the multi display area may be narrower than the virtual image display area. In the above embodiment, the total area of the pointer display areas is ensured to be larger than the area of the multi-display area, but the size relationship between these areas can be changed as appropriate.

  In the above embodiment, when the display of the pointer display area is interrupted, the control for returning the pointer to zero is performed after the process of turning off the pointer light source and the dial light source. However, the order of these processes can be changed as appropriate. In addition, if it is difficult to visually recognize the pointer display area by turning off the pointer light source and the dial light source, only the turning-off process is performed, and the process of returning the pointer to the zero may not be performed.

  In the above embodiment, the virtual image display by HUD can be turned on and off by operating the steering switch. However, the configuration in which such an operation is input is not limited to the steering switch, and may be, for example, a joystick and a touch panel provided in the center console.

  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 of the “display control means” provided by the control unit that executes the program may be provided by hardware and software different from the above-described configuration, or a combination thereof. For example, the above-described functions may be provided by cooperation of control units provided in the combination meter and the HUD, respectively. Furthermore, a function of “display control means” for controlling the HUD and the combination meter so that information is displayed in each display area may be provided by a circuit that performs a predetermined function without depending on a program.
