In particular, in the present embodiment, the control device 7 includes a “normal display (see FIG. 2)” that uses the warning light 9 or the displays 3a and 3b individually according to the type of vehicle information presented to the driver, and the vehicle body symbol 11. And two types of information display methods of “highlighting display (see FIGS. 3 to 6)” that use a combination of the information displayed on the displays 3a and 3b in an integrated manner.

  Here, the control device 7 is physically an electronic circuit mainly including a known microcomputer including a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), an interface, and the like. . Each function of the control device 7 described above is to operate various devices in the vehicle under the control of the CPU by loading an application program held in the ROM into the RAM and executing it by the CPU, and also in the RAM and ROM. This is realized by reading and writing data in. The control device 7 may be configured to be housed inside the vehicle display device 1, or may be configured to be mounted in a vehicle outside the vehicle display device 1 and electrically connected to the vehicle display device 1. Good. In the case where the control device 7 is mounted outside the vehicle display device 1, the function of the control device 7 may be implemented as a part of an ECU (electronic control unit) that controls driving of each part of the vehicle.

  Next, with reference to FIG.2, 3, operation | movement of the display apparatus 1 for vehicles of 1st embodiment is demonstrated. FIG. 2 is a schematic diagram showing a normal display of the vehicle display device of the first embodiment. FIG. 3 is a schematic diagram showing a half-door warning display as an example of vehicle information by highlighting of the vehicle display device of the first embodiment.

  The vehicle display device 1 according to the first embodiment includes a “normal display” shown in FIG. 2 and an “emphasis” shown in FIG. 3 according to the type of vehicle information presented to the driver after the vehicle is started or while the vehicle is running. Two types of information display methods “display” are used properly.

  The “normal display” is a display of the minimum vehicle information necessary for driving, which is presented to the driver during normal driving in which no problem in driving the vehicle occurs. As shown in FIG. 2, in the normal display, for example, information such as the vehicle speed, the accumulated travel distance, the cooling water sound, the remaining amount of fuel, the shift position, etc. is displayed to the driver using the displays 3 a and 3 b or the warning light 9 individually. Presented.

  On the other hand, “highlighted display” is a display of vehicle information required under this condition, which is temporarily presented to the driver when the vehicle is under a specific condition. Specific conditions are those that require some sudden information presentation to the driver, such as when there is a vehicle running problem or when a specific driving task such as starting or garage is performed. Including. As shown in FIG. 3, this highlighting is created by a combination of the vehicle body symbol 11 displayed on the light guide plate 5 by the control device 7 and various information displayed on the displays 3 a and 3 b by the control device 7. Vehicle information is presented to the driver. That is, in the highlighted display, integrated vehicle information is created using two layers of the display 3 a and 3 b and the light guide plate 5.

  In FIG. 3, as an example of the vehicle information by this highlighting, the driver is shown to be in a half-door state when traveling with the vehicle door (the rear seat driver's seat side door in the example of FIG. 3) opened. The half-door warning display 14 for doing this is illustrated. As shown in FIG. 3, the half-door warning display 14 includes a vehicle body symbol 11 displayed on the light guide plate 5 and a door symbol 12 and a comment symbol 13 which are information displayed on the displays 3a and 3b. . As described above, the vehicle body symbol 11 is arranged so as to partially overlap the two displays 3a and 3b when viewed from the front side. The door symbol 12 schematically represents an open door. When viewed from the front side, the end of the rotating shaft overlaps the position of the rotating shaft of the driver side rear door of the vehicle body symbol 11. Is drawn like so. The comment symbol 13 is a character display relating to a detailed description of the half door state. Therefore, when the door symbol 12 and the comment symbol 13 on the display 3a and the vehicle body symbol 11 on the light guide plate 5 arranged on the front side are viewed from the front side, the vehicle door is open. The warning text is presented to the driver as a half-door warning display 14 that integrally displays the warning text. As a result, suddenly necessary information can be displayed in an area larger than the display area of a single display, so that it is possible to provide the driver with easy-to-see and noticeable information.

  In the half-door warning display 14, an animation display indicating that the door is opened and closed may be used as the door symbol 12. As a result, the vehicle state can be presented to the driver more easily.

  In the example of FIG. 3, in order to show that the door on the rear seat driver's seat side is open, the door symbol 12 and the like are displayed only on the right display 3a in the width direction. When warning the situation where the door on the passenger seat side is open, the door symbol 12 or the like is displayed on the display 3b on the passenger seat side. That is, in the highlight display, by using the two displays 3a and 3b and the vehicle body symbol 11 together, it can be displayed as if it were a large integrated display.

  Next, with reference to FIGS. 4-6, the other example of the vehicle information by the highlight display of the display apparatus 1 for vehicles is demonstrated. FIG. 4 is a schematic diagram showing a seat belt warning display as an example of vehicle information by highlighting of the vehicle display device of the first embodiment. The seat belt warning display 16 is presented to the driver when traveling without wearing a seat belt (passenger seat belt in the example of FIG. 4). The seat belt warning display 16 includes a vehicle body symbol 11 displayed on the light guide plate 5 and a seat belt symbol 15 which is information displayed on the displays 3a and 3b. The seat belt symbol 15 represents a seat position where the seat belt is not worn. Therefore, when the seat belt symbol 15 on the display 3b and the vehicle body symbol 11 on the light guide plate 5 disposed on the front side are viewed from the front side, the seat position where the seat belt of the vehicle is removed is integrated. It is presented to the driver as a seat belt warning display 16 displayed automatically.

  FIG. 5 is a schematic diagram showing a tire steering angle display as an example of vehicle information by highlighting of the vehicle display device of the first embodiment. The tire rudder angle display 18 indicates, for example, the rudder angle of the steered wheels (front wheels in the example of FIG. 5) of the vehicle when the vehicle starts or enters the garage. The tire steering angle display 18 includes a vehicle body symbol 11 displayed on the light guide plate 5 and a steering angle symbol 17 which is information displayed on the displays 3a and 3b. The rudder angle symbol 17 represents the rudder angle of the steered wheel, and is drawn so as to be superimposed on the position of the steered wheel (front wheel in FIG. 5) of the vehicle body symbol 11 when viewed from the front side. The rudder angle symbol 17 can be displayed by changing the angle with respect to the vehicle body symbol 11 according to the actual rudder angle of the vehicle, for example. Therefore, when the steering angle symbol 17 on the displays 3a and 3b and the vehicle body symbol 11 on the light guide plate 5 arranged on the front side are viewed from the front side, the steering angle of the tire with respect to the vehicle body is integrated. The tire steering angle display 18 to be displayed is presented to the driver.

  FIG. 6 is a schematic diagram showing a tire air pressure warning display which is an example of vehicle information by emphasis display of the vehicle display device of the first embodiment. The tire pressure warning display 21 indicates to the driver that the tire pressure of the vehicle is decreasing. The tire pressure warning display 21 includes a vehicle body symbol 11 displayed on the light guide plate 5 and a normal tire symbol 19 and a warning tire symbol 20 which are information displayed on the displays 3a and 3b. The normal tire symbol 19 indicates a tire having a normal air pressure. The warning tire symbol 20 indicates a tire in a state where the air pressure is reduced, and is drawn with a color or the like changed so that it can be distinguished from the normal tire symbol 19. The normal tire symbol 19 and the warning tire symbol 20 are drawn so as to be superimposed on the position of each tire of the vehicle body symbol 11 when viewed from the front side. Therefore, when the normal tire symbol 19 and the warning tire symbol 20 on the displays 3a and 3b and the vehicle body symbol 11 on the light guide plate 5 disposed on the front side are viewed from the front side, The tire pressure warning display 21 that integrally displays the tires whose air pressure is reduced is presented to the driver. In the example of FIG. 6, it is displayed that the air pressure of the driver's seat side rear wheel is reduced.

  As described above, the vehicle display device 1 according to the first embodiment shares the vehicle body symbol 11 displayed on the light guide plate 5, while the information displayed on the displays 3 a and 3 b (for example, the above-described door symbol 12, By changing the comment symbol 13, the seat belt symbol 15, the rudder angle symbol 17, the normal tire symbol 19 and the warning tire symbol 20), the vehicle information created by combining these information and the vehicle body symbol 11 is appropriately changed. be able to.

  Next, effects of the vehicle display device 1 according to the first embodiment will be described.

  The vehicle display device 1 according to the first embodiment includes two displays 3a and 3b arranged in parallel at positions that can be viewed from the driver's seat side of the vehicle, and these two displays 3a and 3b when viewed from the driver's seat side. A light guide plate 5 serving as a symbol display unit for displaying the vehicle body symbol 11 between the two, and a control device 7 for controlling information displayed on the two displays 3a and 3b. The control device 7 displays information displayed on the vehicle body symbol 11 and at least one of the two displays 3a and 3b (for example, the aforementioned door symbol 12, comment symbol 13, seat belt symbol 15, rudder angle symbol 17, normal tire symbol 19). And vehicle information to be presented to the driver by highlighting in combination with the warning tire symbol 20).

  With this configuration, two displays 3a and 3b arranged in parallel and the vehicle body symbol 11 displayed between the displays 3a and 3b are combined to include the displays 3a and 3b and a non-display area therebetween. Vehicle information can be created using the entire area and presented to the driver by highlighting. That is, vehicle information can be presented as if a plurality of small displays are large integrated displays. As a result, display with a sense of unity is possible, and the driver of the vehicle can recognize the sense of unity and seamlessness in the display by the vehicle display device 1.

  Moreover, in the vehicle display device 1 according to the first embodiment, the light guide plate 5 as a symbol display unit is disposed closer to the driver's seat (front side) than the two displays 3a and 3b. The vehicle body symbol 11 is arranged on the light guide plate 5 so as to at least partially overlap at least one of the two displays 3a and 3b when viewed from the driver's seat side.

  With this configuration, the vehicle information to be presented to the driver can be created by the two-layer structure of the display layers 3a and 3b and the light guide plate 5 layer. Therefore, when the distance between the displays 3a and 3b is narrow However, the vehicle body symbol 11 can be suitably displayed. That is, the space between the displays 3a and 3b can be arbitrarily reduced without depending on the size of the vehicle body symbol 11, and space can be saved. Furthermore, since the vehicle body symbol 11 can be superimposed on the displays 3a and 3b, the vehicle body symbol 11 on the light guide plate 5 and the information on the displays 3a and 3b can be further linked. Display with a bodily sensation is possible.

  Further, in the vehicle display device 1 of the first embodiment, the light guide plate 5 has a light guide plate light source 10 that makes light incident on the light guide plate 5, and the vehicle body symbol 11 is formed in a concave shape on the light guide plate 5. Has been. The control device 7 switches the operation of the light source 10 for the light guide plate so that the light source 10 for the light guide plate is turned on when the vehicle information is created, and is turned off when the vehicle information is not created.

  With this configuration, since the surface shape of the vehicle body symbol 11 is different from the surface shape of other regions on the main surface of the light guide plate 5, when the light source 10 for the light guide plate is turned on, the light emission state of the vehicle body symbol 11 and other The light emission state of the area is different, and the vehicle body symbol 11 is displayed on the light guide plate 5. In this state, display with a sense of unity is possible by interlocking with the displays 3a and 3b. On the other hand, since the vehicle body symbol 11 is not displayed on the light guide plate 5 when the light source 10 for the light guide plate is turned off, information of a different type from the information using the vehicle body symbol 11 can be presented. In other words, since it is possible to switch the display / non-display of the vehicle body symbol 11 according to whether the light source 10 for the light guide plate is turned on or off, for example, various types of information can be used properly such as the normal display and the highlight display described above. It becomes possible to display, and the amount of information presented to the driver can be increased.

  Moreover, in the vehicle display device 1 of the first embodiment, the light guide plate 5 as a symbol display unit is provided so as to cover the entire display area of the two displays 3a and 3b when viewed from the driver's seat side. With this configuration, the degree of freedom of arrangement of the vehicle body symbol 11 with respect to the displays 3a and 3b can be improved. Further, when the driver views the displays 3a and 3b, the entire display area of the displays 3a and 3b is arranged inside the outer periphery of the light guide plate 5, so that the visibility of the vehicle information presented to the driver can be improved. .

  Moreover, in the vehicle display device 1 of the first embodiment, the control device 7 includes information (for example, the door symbol 12, the comment symbol 13, the seat belt symbol 15, the above-described information displayed on at least one of the two displays 3a and 3b. By changing the rudder angle symbol 17, the normal tire symbol 19, and the warning tire symbol 20), the vehicle information created by combining these information and the vehicle body symbol 11 displayed on the light guide plate 5 is changed. With this configuration, various types of information can be selectively used and presented to the driver even in the highlighted display, and the amount of information presented to the driver can be further increased.

  In the first embodiment, the configuration in which the vehicle body symbol 11 on the light guide plate 5 is not displayed when the light source 10 for the light guide plate is turned off is illustrated. However, the light guide plate does not necessarily need to be completely transparent. What is necessary is just to become relatively hard to see compared with the display state when the light source 10 is turned on. Even in such a state, for example, by adjusting the transmittance of the light guide plate 5, the vehicle body symbol 11 can be configured so as not to be visually recognized by the driver when the light source 10 for the light guide plate is turned off.

  In the first embodiment described above, the vehicle body symbol 11 is exemplified by the configuration formed in the concave shape on the light guide plate 5 by engraving by laser processing, but is not limited thereto, and may be formed by other methods. For example, it is good also as a structure formed by convex shape on the light guide plate 5, such as a technique of stippling with a plurality of dots on the light guide plate 5 or resin molding. Moreover, you may apply the method of transferring on the light-guide plate 5 by printing methods, such as an inkjet screen and nanoimprint. Moreover, you may draw on the light-guide plate 5 by sticking a sticker. Furthermore, in the first embodiment described above, the vehicle body symbol 11 exemplifies a configuration drawn on the light guide plate 5 by line drawing, but the shape of the vehicle body symbol 11 may be a concave shape or a convex three-dimensional shape. .

  In the first embodiment described above, the vehicle body symbol 11 is exemplified to be arranged so as to partially overlap the displays 3a and 3b when viewed from the front side. However, the vehicle body symbol 11 and the displays 3a and 3b The vehicle information may be formed integrally with the above information, and may be arranged in the non-display area in the gap between the displays 3a and 3b without being superimposed on the displays 3a and 3b.

  In the first embodiment, the configuration in which the vehicle body symbol 11 is provided on the light guide plate 5 is illustrated. However, the vehicle body symbol 11 may be provided in a layer different from the displays 3 a and 3 b, for example, instead of the light guide plate 5. A medium having the property may be arranged, and the vehicle body symbol 11 may be formed on the medium.

  In the first embodiment, the light guide plate 5 provided with the vehicle body symbol 11 is provided so as to cover the entire display area of the two displays 3a and 3b when viewed from the driver's seat side. 11, the outer peripheral shape of the display 3a, 3b is smaller than the entire display area, such as a size that fits in the non-display area between the two displays 3a, 3b. May be.

  Moreover, in said 1st embodiment, the vehicle display apparatus 1 uses "normal display" and "highlighted display" properly, and also more than one vehicle information (half-door warning display 14, seatbelt warning displayed in highlight display) Although the configuration in which the display 16, the tire steering angle display 18, and the tire pressure warning display 21) are selectively used has been illustrated, a configuration in which only single vehicle information is presented in the highlighted display may be used. Moreover, as vehicle information presented in the highlighting, information other than the vehicle information described above with reference to FIGS. 3 to 6 may be applied.

[Modification of First Embodiment]
Next, a modification of the first embodiment will be described with reference to FIG. The vehicle body symbol 11 for creating integrated vehicle information in combination with the information of the displays 3a and 3b may be created on the dial 4 instead of the light guide plate 5 as in the first embodiment. In the vehicular display device 1a according to the modification of the first embodiment shown in FIG. 7, a vehicle body symbol 11a is provided in a non-display area 4a on the dial 4 which is a gap between the displays 3a and 3b. Similar to the warning lamp 9, the dial 4 also has transparency in the portion on which the vehicle body symbol 11a is drawn, and turns on / off the warning light source 8 disposed on the back side of the vehicle body symbol 11a.
