[0022] [Figure 1] This is a view of the front door of the vehicle according to this embodiment, as seen from inside the vehicle. [Figure 2] This figure shows the case where an image is displayed on the front door shown in Figure 1. [Figure 3] This is a cross-sectional view taken along line 3-3 in Figure 2. [Figure 4] Figure 3 is a schematic diagram showing the lamination configuration of the interior materials. [Figure 5] A block diagram showing the hardware configuration of the vehicle, as shown in Figure 1. [Figure 6] This is a schematic diagram showing the pattern of through-holes in the door trim of a modified vehicle. [Modes for carrying out the invention]

[0023] The following description of a vehicle 10 according to one embodiment of the present invention will be made using Figures 1 to 5. The arrows FR, UP, LH, and RH shown in each figure indicate the front, top, left (width direction), and right (width direction) of the vehicle 10, respectively. Furthermore, in the following description, unless otherwise specified, the directions front / back, up / down, and left / right refer to the front / back, up / down, and left / right directions of the vehicle, respectively.

[0024] Figure 1 shows the area around the driver's seat as seen from the passenger side inside the passenger compartment 12 of the vehicle 10 according to this embodiment. As an example, the vehicle 10 is a left-hand drive vehicle with the steering wheel 14 located on the left side. The steering wheel 14 is mounted on the rear side of the instrument panel 16, which extends substantially in the vehicle width direction at the front of the passenger compartment 12, and on the front side of the driver's seat.

[0025] A windshield glass 18 is positioned above the instrument panel 16. The windshield glass 18 slopes downward toward the front of the vehicle, separating the interior from the exterior of the passenger compartment 12.

[0026] The left end of the windshield glass 18 is fixed to the inside in the vehicle width direction of the left front pillar 20 of the vehicle, which extends approximately vertically. Similarly, the right end of the windshield glass 18 is fixed to the right front pillar of the vehicle (not shown).

[0027] The upper end of the front pillar 20 is joined to the front end of a roof side rail (not shown) that extends approximately in the longitudinal direction of the vehicle on the left side of the roof (not shown). The lower end of the front pillar 20 is joined to the front end of a rocker (not shown) that extends approximately in the longitudinal direction of the vehicle on the left side of the floor (not shown).

[0028] The front pillar 20, roof side rail (not shown), center pillar (not shown), and rocker (not shown) all have a closed cross-section structure and constitute the frame of the vehicle 10. On the left side of the vehicle 10, a front door opening 22 is formed, enclosed by the front pillar 20, roof side rail (not shown), center pillar (not shown), and rocker (not shown). The front door opening 22 is opened and closed by the front door 24. An opening weatherstrip (not shown) is attached to the opening edge of the front door opening 22.

[0029] As shown in Figure 2, the front door 24 is configured to display an image on the inside of the passenger compartment 12. Figure 3 shows a cross-sectional view of the front door 24 shown in Figure 2, taken from the rear of the vehicle, along line 3-3. The front door 24 has a closed cross-sectional structure, comprising a door outer panel 26 located on the outside of the passenger compartment and a door inner panel (not shown) located on the inside of the passenger compartment. A door weatherstrip (not shown) is attached to the periphery of the front door 24.

[0030] A front side glass 28 is positioned between the door outer panel 26 and the door inner panel (not shown). The front side glass 28 is slidable vertically by a power window device (not shown).

[0031] Furthermore, at the lower part of the front door 24, multiple displays 30, which serve as display devices, are arranged in a line approximately in the vertical direction of the vehicle on the inside of the passenger compartment 12 of the door inner panel (not shown). The door inner panel (not shown) is provided with a recess that is indented toward the outside of the passenger compartment, and the multiple displays 30 are arranged in this recess. One example of a display 30 is an LED (Light-Emitting Diode) display, which is equipped with multiple light-emitting diodes (not shown) as light-emitting elements on the inside of the passenger compartment 12. Note that the display is not limited to an LED display, but may also be an organic EL (Electro-Luminescence) display. Also, the display device is not limited to a display, but may be composed of multiple arranged LEDs. Furthermore, the arrangement of the displays is not limited to the above, and may be arranged in a line in the front-rear direction of the vehicle, for example. The display may consist of only one unit.

[0032] On the interior side of the passenger compartment 12 behind the display 30, a door trim 32 is provided as an interior material that constitutes the design surface inside the passenger compartment 12. For example, the door trim 32 is made of bamboo. Multiple displays 30 are arranged at an angle to conform to the shape of the door trim 32. Alternatively, the multiple displays 30 may be arranged on the same plane.

[0033] The door trim 32 has a plurality of slits 34 that penetrate in the thickness direction. The door trim 32 is arranged so that the plurality of slits 34 are located on the interior side of the light-emitting diodes of the display 30. Each of the plurality of slits 34 is formed in a straight line along the longitudinal direction of the vehicle and is formed at equal intervals in the vertical direction of the vehicle inside the frame portion 36. As an example, the width of each slit 34 in the vertical direction of the vehicle and the width of the grid portion 38 between the slits 34 in the vertical direction of the vehicle are assumed to be the same dimension.

[0034] The shape and dimensions of the slit 34 are not limited to those described above. For example, the vertical dimension of the slit may be larger than the vertical dimension of the grid section. In this case, occupants in the passenger compartment 12 can see the image displayed on the display 30 more clearly. Alternatively, the vertical dimension of the slit may be smaller than the vertical dimension of the grid section. In this case, the texture of the door trim 32 as seen from inside the passenger compartment 12 is emphasized, and the design is improved when no image is displayed on the display 30. Furthermore, the slit is not limited to a straight line; it may also be formed in a curved shape. For example, multiple through-holes may be arranged so that the entire door trim forms a predetermined pattern such as a wave or radial shape.

[0035] Although not shown in the illustration, the door trim 32 is provided with an armrest, an inner handle, and a window switch. The armrest (not shown) is located in the vertical center of the door trim 32, extends in the longitudinal direction of the vehicle, and protrudes into the interior of the passenger compartment 12. The door trim 32 may also be equipped with storage pockets and a speaker. The front right front door (not shown) of the vehicle 10 has the same configuration as the front door 24, so its description is omitted.

[0036] As shown in Figure 4, the door trim 32 is a laminate in which thin bamboo sheets 32A, 32B, and 32C, which are sheet-like members, are stacked in the thickness direction.

[0037] The bamboo sheet 32A is a thin sheet that can be freely deformed and has multiple slits 34A that penetrate in the thickness direction. Each of the multiple slits 34A is formed in a straight line along the front-rear direction of the vehicle and is arranged at equal intervals in the vertical direction of the vehicle inside the frame portion 36A.

[0038] The bamboo sheet 32B has the same configuration as the bamboo sheet 32A, and is composed of a frame portion 36B, a plurality of slits 34B, and a plurality of grid portions 38B. Similarly, the bamboo sheet 32C has the same configuration as the bamboo sheets 32A and 32B, and is composed of a frame portion 36C, a plurality of slits 34C, and a plurality of grid portions 38C.

[0039] The bamboo sheets 32A, 32B, and 32C are folded to match the design of the front door 24, laminated, and glued to each other. At this time, the bamboo sheets 32A, 32B, and 32C are overlapped so that the positions of the slits 34A, 34B, and 34C coincide in the sheet thickness direction (vehicle width direction). This creates slits 34 that penetrate in the thickness direction in the laminated door trim 32. In this embodiment, the door trim 32 of the vehicle 10 is assumed to be formed by bonding the bamboo sheets 32A, 32B, and 32C across their entire overlapping surfaces, but is not limited to this. For example, the door trim may be bonded only to the frame portion of each bamboo sheet. Also, although the door trim 32 has been described as being made up of three laminated bamboo sheets 32A, 32B, and 32C, the number of laminated sheet members is not limited to this. Furthermore, in Figure 4, for the sake of explanation, the bamboo sheets 32A, 32B, and 32C are depicted as rectangular sheets, but in reality, they are shaped to match the shape of the door trim 32.

[0040] (Hardware configuration of vehicle 10) As shown in Figure 5, the vehicle 10 is equipped with an ECU (Electronic Control Unit) 40. The ECU 40 consists of a CPU 42, ROM 44, RAM 46, storage 48, and an input / output interface (I / F) 50. Each component is connected to the others so as to be able to communicate with each other via an internal bus 52.

[0041] The CPU 42 is a central processing unit that executes various programs and controls various parts. Specifically, the CPU 42 reads programs from the ROM 44 or storage 48 and executes them using the RAM 46 as a working area. The CPU 42 also controls the display 30 according to the programs recorded in the ROM 44 or storage 48.

[0042] ROM 44 stores various programs and data. RAM 46 temporarily stores programs or data as a working area. Storage 48 is a non-temporary recording medium consisting of an HDD or SSD that stores various programs and data.

[0043] Multiple displays 30 and sensors 54, which serve as surrounding monitoring sensors for monitoring the area around the vehicle 10, are connected to the input / output interface 50. The sensors 54 include multiple sensors from among various types of sensors such as cameras, radar, and LiDAR (Light Detection and Ranging). The cameras capture images of the area around the vehicle 10. The radar detects the distance and direction of objects around the vehicle 10 using radio waves. The LiDAR detects the distance and direction of objects around the vehicle 10 using laser light. Note that the surrounding monitoring sensors only need to include at least one of these sensors.

[0044] The CPU 42 outputs various displays to the display 30. For example, if the sensors 54 detect an obstacle approaching the vehicle 10, the CPU 42 outputs a warning message to the display 30.

[0045] For example, if another vehicle approaches vehicle 10 from the left rear, or if a motorcycle is passing to the left of vehicle 10 and attempting to overtake it, the CPU 42 displays an image resembling an exclamation mark as a warning on the left front door 24 of the vehicle, as shown in Figure 2. On the other hand, if another vehicle approaches vehicle 10 from the right rear, or if a motorcycle is passing to the right of vehicle 10 and attempting to overtake it, a warning display is output to the display on the right front door (not shown). This allows the occupant to instantly recognize vehicles approaching from the left or right rear. Note that in Figure 2, the display is exaggerated for illustrative purposes, but in reality, the light passing through the slit 34 (see Figures 3 and 4) is clearly displayed. Also, while Figure 2 shows an image resembling an exclamation mark as an example, the warning display is not limited to this.

[0046] Furthermore, the CPU may, for example, display images on the left front door 24 and the right front door (not shown) of the vehicle, so that light flows from the front to the rear of the vehicle, when the vehicle 10 is exceeding the legal speed limit or is about to exceed it. This allows the driver to perceive from inside the cabin 12 that the vehicle 10 is going too fast.

[0047] Furthermore, the CPU 42 may output images to the display 30 that create an atmosphere within the vehicle compartment 12. For example, the CPU 42 may obtain the outside temperature from an outside temperature sensor (not shown) and output a warm-colored display to the display 30 when the outside temperature is low, and a cool-colored display when the outside temperature is high. This allows the occupants to feel warm on cold days with a warm-colored display and cool on hot days through visual effects. In addition, the CPU 42 may obtain the occupant's body temperature from a biosensor (not shown), not limited to the outside temperature sensor, and output a warm-colored display to the display 30 when the body temperature is low and a cool-colored display when the body temperature is high.

[0048] Furthermore, for example, the CPU 42 may output a relaxing image to the display 30 when the occupant is tense, based on information acquired from a biosensor (not shown). Also, for example, the CPU 42 may output an image to the display 30 that attracts the occupant's attention and encourages wakefulness when the occupant appears sleepy. Furthermore, for example, the CPU 42 may output an image to the display 30 that is synchronized with music output from a speaker (not shown) in the passenger compartment 12. These images that create the atmosphere of the space inside the passenger compartment 12 are, for example, always output to the display 30 when the power of the vehicle 10 is ON. Note that the timing of image output is not limited to this; for example, the CPU 42 may output an image to the display 30 when it becomes dark outside the passenger compartment 12, based on information acquired from an illuminance sensor (not shown).

[0049] (Operation of this embodiment) Next, the operation of the vehicle 10 according to this embodiment will be described.

[0050] In the vehicle 10 according to this embodiment, the display 30 is covered by the door trim 32. Therefore, compared to the case where the display 30 is exposed inside the passenger compartment 12, the aesthetic design of the interior when the light-emitting diode (not shown) is not emitting light can be maintained.

[0051] Furthermore, the light emitted from the light-emitting diodes of the display 30 passes through the slit 34 of the door trim 32 and reaches the space inside the passenger compartment 12. Therefore, compared to the case where a transparent panel is placed inside the display 30, the light emitted from the light-emitting diodes reaches the space inside the passenger compartment 12 directly, allowing for the display of a clear image.

[0052] Furthermore, according to the vehicle 10 of this embodiment, the bamboo sheets 32A, 32B, and 32C are each thin and can be bent freely. Therefore, by bending the bamboo sheets 32A, 32B, and 32C and then laminating them, it is possible to ensure the strength of the door trim 32 while conforming to the three-dimensional shape of the interior of the passenger compartment 12.

[0053] Furthermore, according to the vehicle 10 of this embodiment, the slit 34 of the door trim 32 is formed along the longitudinal direction of the vehicle in the front door 24. Therefore, the light emitting in a flowing manner in the longitudinal direction of the vehicle can be continuously and uninterruptedly seen by the occupants.

[0054] Furthermore, according to the vehicle 10 of this embodiment, if an obstacle is detected around the vehicle 10 by the sensors 54, a warning message is displayed on the display 30. The occupant can see this warning message through the slit 34 formed in the door trim 32. Thus, the occupant can be warned with a clear image while maintaining the aesthetic design of the interior of the passenger compartment 12.

[0055] Furthermore, according to the vehicle 10 of this embodiment, slits 34A are formed in the bamboo sheet 32A, slits 34B are formed in the bamboo sheet 32B, and slits 34C are formed in the bamboo sheet 32C. In other words, since slits 34A, 34B, and 34C are formed in the thin bamboo sheets 32A, 32B, and 32C respectively, processing to form the slits 34A, 34B, and 34C is easy, and damage to the members can be suppressed compared to a manufacturing method in which sheet-like members are laminated and then through holes are formed. Note that interior materials may also be constructed by laminating sheet-like members and then forming through holes.

[0056] [Supplementary explanation of the above embodiment] In the above embodiment, a display 30 is provided on the front door 24 and a plurality of slits 34 are formed in the door trim 32, but the embodiment is not limited to this.

[0057] For example, the display device may be located inside the instrument panel, and a slit may be formed in the panel trim covering the display device, with the vehicle width direction as the longitudinal direction. In this case, the occupants can continuously see the light emitting in a flowing manner in the vehicle width direction without interruption. In this case, a warning display may also be output to the instrument panel display device when the vehicle is getting too close to the vehicle in front.

[0058] Furthermore, the display device may be installed in other locations within the vehicle interior, such as the rear door, tailgate, roof, or floor, in which case a slit is formed in the corresponding interior material. For example, a display device may be installed in the rear door of a taxi, and a relaxing image may be displayed on the device for the passengers. In addition, multiple display devices may be installed in the vehicle interior in combination with the above-mentioned locations. Furthermore, through-holes may be formed not only in the interior material covering the display device, but also in the interior material of other parts of the vehicle interior. This creates a sense of unity in the design of the vehicle interior and improves its aesthetic appeal.

[0059] Furthermore, although the above embodiment described the door trim 32 as a laminate formed by stacking bamboo sheets 32A, 32B, and 32C, it is not limited to this and may be composed of a single, unlaminated member.

[0060] Furthermore, the interior materials are not limited to bamboo; they may be made of other materials. For example, the interior materials may be wood made by laminating multiple sheets of wood with perforations. Alternatively, the interior materials may be made of woven rattan so that light can pass through the weave. In this way, using natural materials as interior materials can give occupants a sense of natural warmth. In addition, reducing the amount of interior materials made of chemical products can reduce the environmental burden, but the interior materials may also be made of artificial materials such as resin.

[0061] Furthermore, although the above embodiment was described as having multiple slits 34 formed in the door trim 32 with the longitudinal direction of the vehicle in the front-rear direction, it is not limited to this. For example, multiple slits may be formed in the door trim with the longitudinal direction of the vehicle in the up-down direction. Also, the shape of the through-holes is not limited to slits. For example, as shown in the modified example in Figure 6, multiple circular through-holes 62 may be formed in the sheet-like members 60A, 60B, and 60C that constitute the door trim 60. Also, the shape and size of the multiple through-holes do not have to be the same. Furthermore, the through-holes do not have to be arranged at equal intervals. For example, by expressing shades of gray by varying the density of the multiple through-holes, a pattern containing a specific picture or character may appear on the interior material when the display device is turned off.

[0062] The following additional information is disclosed regarding the embodiments described above.
