Description

TECHNICAL FIELD

[0001] The present application relates to a vehicle. BACKGROUND

[0002] In recent years, vehicles equipped with cameras that capture images inside the vehicle cabin have been increasing. However, in order to capture the entire image of the inside of the vehicle cabin inside the vehicle cabin, there are problems with the placement of the camera. For example, Patent Documents 1 and 2 describe vehicles in which a camera is provided on the ceiling of the vehicle cabin.

[0003] Patent Document 1: Japanese Patent Application Publication No. 2012-126357

[0004] Patent Document 2: Japanese Patent Application Publication No. 2019-219899 SUMMARY

[0005] Most of the cameras inside the vehicle cabin are provided on the upper front portion of the center of the vehicle. In this case, the angle of view inside the vehicle cabin is fixed to one, making it difficult to capture the entire inside of the vehicle cabin. When a camera is provided inside the vehicle cabin, it is desirable that the interior decoration inside the vehicle cabin maintain a sense of unity and not interfere with the driver's driving.

[0006] The present application is a vehicle that does not interfere with the driver's driving and can capture the entire inside of the vehicle cabin from a camera.

[0007] To solve the above problems, the present application employs the following solutions.

[0008] (1) The vehicle of the present application has a central display, a side display for a side camera monitoring system, and a camera that captures the inside of the vehicle cabin, which is disposed on the upper portion of the side display and on the center side of the vehicle.

[0009] With the above structure, the driver's driving is not interfered with, and the camera is disposed to capture the inside of the vehicle cabin from the side of the driver, so the camera is not easily hidden in the shadow of the driver's body and the bodies of the passengers seated next to the driver, and the entire inside of the vehicle cabin can be captured.

[0010] (2) In the above (1), the vehicle can also have a connection portion between the central display and the side display, and the camera can be disposed within the range of the height direction of the central display.

[0011] In this case, the camera does not protrude above the height direction of the central display, so it does not interfere with the driver's driving. The camera does not protrude below the height direction of the central display, so it can capture the entire inside of the vehicle cabin.

[0012] (3) In the aspect of (2) above, the camera can have a connection terminal on the central display side, and the connection terminal can be disposed in the area of the connection portion.

[0013] In this case, even if the connection terminal of the camera protrudes from the side display, it can be accommodated between the side display and the central display.

[0014] (4) In the aspect of (1) above, the camera can be disposed such that the tilt angle of the camera is different from the tilt angle of the side display.

[0015] In this case, even if the orientation of the side display is set considering the influence of visual recognition, reflected light, etc., the orientation of the camera can be set to an angle suitable for the shooting range.

[0016] (5) In the aspect of (4) above, the tilt angle of the camera can be set such that the face of the occupant is disposed in the vertical direction center of the shooting range of the camera.

[0017] In this case, it is easy to include the face of the occupant, who is the subject, in the shooting range, and an image in which the expression of the subject can be focused on can be shot.

[0018] (6) In the aspect of (1) above, the side display can be disposed at least on the side of the front passenger seat, and the camera can be disposed on the side display on the side of the front passenger seat.

[0019] In this case, compared to the case where the camera is disposed on the side of the driver's seat, the proportion of the steering device in the shooting range can be suppressed.

[0020] According to the aspect of the present application, the driver's driving will not be hindered, and the entire interior of the vehicle cabin can be shot from the camera. BRIEF DESCRIPTION OF DRAWINGS

[0029] Hereinafter, the present application will be described based on a preferred embodiment.

[0030] Figure 1 is a perspective view schematically showing the inside of a vehicle cabin 10 of a vehicle 100 of the present embodiment.

[0031] Figure 2 is a perspective view showing an example of a display 20 arranged in the vehicle cabin 10. Figure 2 An arrow UP indicating the upper side of the vehicle 100, an arrow FR indicating the front side of the vehicle 100, and an arrow LH indicating the left side of the vehicle 100 are shown in the figure.

[0032] The vehicle 100 is provided with an instrument panel 11, a driver seat 12, a front passenger seat 13, a steering device 14, and the like in the vehicle cabin 10.

[0033] The driver seat 12 is a seat arranged in front of the vehicle 100 for use by a driver. The front passenger seat 13 is a seat arranged beside the driver seat 12 in front of the vehicle 100 for use by an occupant other than the driver. The driver seat 12 and the front passenger seat 13 are front passenger seats arranged in front of the vehicle 100.

[0034] Although not particularly shown, one or more rows of passenger seats can be provided in the vehicle cabin 10 behind the front passenger seats. The occupant seated on the front passenger seat 13 is not limited to whether or not the occupant assists the driver when the vehicle 100 is driven, and there can be no occupant on the front passenger seat 13. In the illustrated example of the vehicle 100, the driver seat 12 is arranged on the left side of the front passenger seat 13, but the driver seat 12 can be arranged on the right side of the front passenger seat 13 instead of the illustrated example. The number of seats, the arrangement, and the like are not limited to the illustrated example, and can be appropriately changed.

[0035] The vehicle 100 is provided with a center display 21, a side display 22 for a side camera monitoring system, and a photographing camera 31 that photographs the inside of the vehicle cabin 10. The center display 21 of the illustrated example is mounted to the instrument panel 11. A front window 15F is arranged in front of the center display 21.

[0036] The display 20 of the illustrated example has side displays 22 on the left and right of the central display 21. More specifically, the central display 21 is composed of a driver seat side central display 21A and a front passenger seat side central display 21B. The side displays 22 are composed of a driver seat side side display 22A and a front passenger seat side side display 22B.

[0037] The driver seat side central display 21A and the front passenger seat side central display 21B are disposed at a central display mounting portion 23 of the display 20. The side displays 22 are disposed at a side display mounting portion 24. In the preferred embodiment, the display 20 includes the central display mounting portion 23 and the side display mounting portion 24.

[0038] In the central display 21 of the illustrated example, the driver seat side central display 21A is in a rectangular shape that is smaller than the front passenger seat side central display 21B, but the disposition, shape, size, etc. of each central display 21 are not particularly limited. It is also possible to divide the display surface into a plurality of surfaces and display information for the driver and information for other occupants on the same central display 21.

[0039] The photographing camera 31 is disposed at the upper portion of the side display 22 on the center C side of the vehicle 100.

[0040] The upper portion of the side display 22 refers to the area above the side display 22 in the vertical direction of the vehicle 100. In the lateral direction, as long as it is disposed at the side display mounting portion 24, it can be directly above the side display 22 or it can be diagonally above the side display 22.

[0041] In the case where the lateral direction of the side display 22 is divided into a side close to the center C and a side away from the center C, the center C side of the vehicle 100 refers to the side close to the center C. The center C of the vehicle 100 indicates the position of the longitudinal center plane.

[0042] The side display 22 is a side display 22 for a side camera monitoring system. The side camera monitoring system is an image pickup device disposed at a position that can be visually recognized by the driver, which picks up an image of the rear of the vehicle or the like from the outside of the vehicle 100.

[0043] With the above-described structure, the photographing camera 31 can pick up the inside of the vehicle cabin 10 from the side of the driver. Compared to the case where a camera is disposed at the upper front portion of the center of the vehicle 100, the driver's driving is not hindered. The photographing camera 31 is less likely to be hidden in the shadow of the body of the occupant in front of the vehicle 100, and thus the entire inside of the vehicle cabin 10 can be picked up from the photographing camera 31.

[0044] The display 20 shown in the illustration is a display module integrally mounted with a center display 21 and side displays 22. A connecting portion 25 is disposed between the center display 21 and the side displays 22. More specifically, the side display mounting portions 25 are connected to the left and right sides of the center display mounting portion 23. Although not specifically shown, the side displays 22, each equipped with an image capture camera 31, can be mounted on the vehicle 100 as a separate component from the center display 21.

[0045] The display 20 of this embodiment includes a central display 21 , a side display 22 for a side camera monitoring system, and a camera 31 for capturing images of the interior of the vehicle cabin 10 . The camera 31 is disposed above the side display 22 and on the center C side of the vehicle 100 .

[0046] The camera 31 is preferably positioned within the height range of the center display 21. In this case, the camera 31 does not protrude above the center display 21. Therefore, compared to a case where the camera 31 is positioned above the center display 21, the driver's field of view is not obstructed, and the camera 31 is less likely to be mistaken for another object, thereby hindering the driver's driving. Compared to a case where the camera 31 protrudes below the center display 21, it is easier to achieve a position that captures the entire interior of the vehicle cabin 10.

[0047] Figure 1 and Figure 2 The position of the camera 31 shown is the position of the light receiving unit of the camera 31. The light receiving unit of the camera 31 is arranged on the display surface side of the side display 22. Although not specifically shown, the camera 31 may include various mechanisms such as an image processing unit behind the light receiving unit.

[0048] Figure 3 It is from Figure 2 A perspective view of the side display 22 as viewed from portion A. Figure 4 1 and 2 are plan views showing the arrangement of the imaging camera 31 at the side display 22. In these drawings, the illustration of components that are not necessary for explanation may be omitted as appropriate.

[0049] like Figure 3 As shown, the camera 31 has a connection terminal 32, such as a connector, on the side of the center display 21. A bracket 33 secures the camera 31 to the front surface of the side display mounting portion 24. Like the center display 21 and the side display 22, the camera 31 receives power from a power source within the vehicle 100. A cord 34 is connected to the connection terminal 32. The cord 34 is connected to a connector 35 on the side of the center display 21.

[0050] The power supply in the vehicle 100 can be a device that supplies electric power to a power source provided with a power source driven by electric power, or can be a storage battery provided in a vehicle driven by an internal combustion engine. As the vehicle provided with a power source driven by electric power, there are listed an electric motor vehicle, a fuel cell motor vehicle (FCV), and the like. As the electric motor vehicle, there are listed a battery electric vehicle (BEV), a hybrid electric vehicle (HEV) provided with an internal combustion engine that supplies at least a part of power, a plug-in hybrid electric vehicle (PHEV), and the like.

[0051] The connection terminal 32 of the photographing camera 31 is preferably arranged in a region of the connecting portion 25 of the center display 21 and the side display 22. In this case, even if the connection terminal 32 protrudes from the side display 22, it is housed in the recess 26 between the center display 21 and the side display 22, and the connection terminal 32 is arranged hidden in the back of the display 20. Compared with the case where the connection terminal 32 protrudes upward of the side display 22 or the like, the driver's field of view is not obstructed, or the connection terminal 32 is not mistaken for another object, and the driver's driving is not easily hindered.

[0052] Figure 5 is a front view showing the arrangement of the photographing camera 31 from the display surface side of the side display 22. Figure 6 is a sectional view along the B-B line of Figure 5 As shown in Figure 6 , the photographing camera 31 is preferably arranged such that the inclination angle 37 of the photographing camera 31 is different from the inclination angle 27 of the side display 22.

[0053] In the illustrated example, the inclination angle 27 is set along the display panel 28 that forms the display surface of the side display 22. The inclination angle 37 of the photographing camera 31 is different from the inclination angle 27 of the side display 22 by an angle a. The size of the angle a is not particularly limited.

[0054] The inclination angle 27 of the side display 22 is set considering the influence of visual recognition from the driver, reflected light, and the like on the driver. The inclination angle 27 is, for example, an angle at which the display surface of the display panel 28 is inclined with respect to the upper side of the vehicle.

[0055] The inclination angle 37 of the photographing camera 31 does not need to be good for visual recognition from the driver and other passengers, and is set to an angle suitable for the photographing range. The inclination angle 37 is, for example, an angle at which the light receiving surface 36 of the photographing camera 31 is inclined with respect to the upper side of the vehicle. In the case where the light receiving surface 36 is not planar, the inclination angle 37 can be set along a plane perpendicular to the incident light axis passing through the light receiving surface 36.

[0056] In the illustrated example, the tilt angle 37 of the photographing camera 31 is set to an angle smaller than the tilt angle 27 of the side display 22, in a case where the tilt angles 27, 37 are defined as angles tilted with respect to the upper side of the vehicle. Although not particularly illustrated, the tilt angle 37 of the photographing camera 31 can also be set to an angle larger than the tilt angle 27 of the side display 22.

[0057] The tilt angle 37 of the photographing camera 31 can be set to match the viewpoint of an AM50 dummy. The AM50 dummy is a model covering 50% of an American adult male among dummies for a crash test. In this case, it is easy to include the face of an occupant seated in the front passenger seat in the photographing range (refer to the photographing range 40 of the photographing camera 31 described later) of the photographing camera 31, and it is easy to photograph an image in which the expression of the occupant who becomes the subject can be focused on. In a case where the tilt angle 37 is set to match the viewpoint of the dummy, if the tilt angles 27, 37 are made different, the tilt angle 27 of the side display 22 is set to an angle different from the angle matching the viewpoint of the dummy. The dummy (refer to the dummy 41 of the photographing camera 31 described later) used for adjustment of the tilt angle 37 is not limited to the AM50 dummy, and can be set based on a JM50 dummy (a model covering 50% of a Japanese adult male) or the like. Figure 7 Figure 7 The viewpoint of the dummy can be frontward observation or sideward observation, as long as it is a position at which the line of sight of the dummy provided to the seat is directed. For example, when the face of the dummy is directed in the direction of the side display 22, the light receiving portion of the photographing camera 31 can be directed in the direction of the eyes of the dummy. When the face of the dummy is directed in the front direction of the vehicle 100, the light receiving portion of the photographing camera 31 can be directed in the direction of the eyes of the dummy.

[0058] The photographing camera 31 is preferably disposed on the side display 22B on the passenger seat side. As compared with a case where the photographing camera 31 is disposed on the side display 22A on the driver seat side, it is possible to suppress the proportion of the steering device 14 occupying in the photographing range of the photographing camera 31. The photographing camera 31 can also be disposed on both the side display 22A on the driver seat side and the side display 22B on the passenger seat side.

[0059]

[0060] Figure 7 ​​is a conceptual diagram showing an example of the photographing range 40 photographed by the photographing camera 31. The tilt angle 37 of the photographing camera 31 is preferably set so that the face of the occupant is disposed in the vertical direction center of the photographing range 40 of the photographing camera 31. In the photographing range 40 of the illustrated example, a dummy 41 provided in the driver seat 12, i.e., a driver dummy 42, a dummy 41 provided in the front passenger seat 13, i.e., a front passenger dummy 43, and the like are photographed. The faces (may be the eyebrows, nose, and the like) of the driver dummy 42 and the front passenger dummy 43 are preferably disposed in the substantially vertical direction center portion of the photographing range 40. By changing the tilt angle 37 of the photographing camera 31, the position of the face of the dummy 41 in the vertical direction of the photographing range 40 can be adjusted. The dummy 41 used in the adjustment of the photographing range 40 can be a dummy 41 disposed in the driver seat 12, the front passenger seat 13, or another position in the vehicle cabin 10, and further, a plurality of dummies can be used.

[0061] Further, the photographing range 40 preferably includes the steering device 14. Thereby, the driving posture of the driver can be recorded.

[0062] Further, the photographing range 40 preferably enables a half-body shot of each dummy 41, which becomes the subject, including the chest. Thereby, the expressions and the upper body movements of the driver and the front passenger in the vehicle cabin 10 can be recorded.

[0063] Further, the photographing range 40 preferably includes the side window 15S, the rear window 15R, and the like. Thereby, the moving scenery of the vehicle can be recorded, and thus the situation outside the vehicle can be confirmed. In particular, the weather, the time, and the like can be confirmed depending on the light amount and the like outside the vehicle. These windows can be door windows, or can be fixed to the vehicle body. These windows can be openable and closable, or can be non-openable and non-closable.

[0064] Further, the photographing range 40 preferably includes at least one of the pillar 16 and the roof 17 in the vehicle cabin 10. Thereby, the pillar 16 and the roof 17 function as a frame with respect to the images of the driver and the front passenger, and the movements of the driver and the front passenger are easily focused on by the observer observing the images by the frame effect.

[0065] Figure 8 is a block diagram showing an example of a processing procedure in photographing using the photographing camera 31. The processing procedure 50 of the illustrated example includes a photographing step 51, a morphing correction step 52, and a display step 53. The photographing step 51 is a step of photographing the inside of the vehicle cabin 10, and can be performed using the photographing camera 31. As described above, the photographing range 40 preferably includes the scenery outside the vehicle. The image can be in color, or can be in black and white. The light used for photographing is not limited to visible light such as three primary colors (RGB), and can be infrared rays and the like.

[0066] The deformation correction process 52 is a process of correcting the deformation of the image obtained in the photographing process 51. The image processing circuit configured outside the photographing camera 31 can be used in the deformation correction process 52, or the image processing circuit built in the photographing camera 31 can be used. The image processing circuit can also be attached to the display 20.

[0067] The display process 53 is a process of displaying the image corrected in the deformation correction process 52. The central display 21 or the side display 22 can be used in the display process 53. In the display process 53, the image can also be displayed on a display outside the vehicle. For example, the image obtained in the photographing process 51 or the image corrected in the deformation correction process 52 can be saved in a storage device, and the saved image can be displayed afterward. The image can also be transmitted to the outside of the vehicle through wireless communication or the like, and the image received outside the vehicle can be displayed in real time or afterward.

[0068] The present application is not limited to the above-described embodiments, and various design modifications can be made without departing from the spirit of the application. As the vehicle, a motor vehicle having a vehicle cabin is exemplified. As the motor vehicle, there is no particular limitation, and for example, a motor vehicle having four to eight wheels is exemplified, and more specifically, a passenger car, a truck, or the like is exemplified. The display provided with the photographing camera described above can also be applied to other moving bodies, transport equipment, or the like.
