And a reflection member that reflects toward the driver.

  In this driving support device, at least a part of the vehicle outside area that becomes the blind spot of the driver is imaged by the imaging means. The image picked up by the image pickup means and displayed on the display means is reflected toward the driver by the reflecting member provided in the vehicle component that forms the blind spot. As a result, the image of the blind spot area is visually recognized by the driver as a virtual image located (feels like) on the vehicle outer side (the far side) with respect to the vehicle component that forms the blind spot.

  Here, since the reflecting member has a plurality of reflecting surfaces, an image displayed by the display unit is reflected toward the driver by a different reflecting surface for each display area of the display unit. For this reason, in the configuration in which the reflecting member is provided in the vehicle component, the display image of each part (display region) of the display means can be reflected toward the driver by setting the reflection angle of each reflecting surface. That is, when providing a reflective member in a vehicle component, it is possible to ensure the degree of freedom of arrangement of the display means.

Image size adjusting means for enlarging or reducing the reflected image is further provided.

  In this driving support device, the size of the image reflected toward the driver is adjusted by the image size adjusting means. Thereby, for example, when the distance from the display means to the driver via the reflecting surface (hereinafter referred to as “viewing distance”) is different for each reflecting surface, the driver visually recognizes the difference in the viewing distance. The image size is adjusted so that the difference in image size is reduced.

  According to a fourth aspect of the present invention, there is provided the driving support apparatus according to the third aspect, wherein the image size adjusting means includes an optical member that optically enlarges or reduces the image size for each reflection surface.

  In this driving support device, the image size visually recognized by the driver can be adjusted with a simple structure by the optical member.

[Visual Information Auxiliary Device]
The visual information assisting device 10 is configured to cause the driver D to visually recognize the visual information of the vehicle outside area that is a blind spot for the driver D. This will be specifically described below.

  As shown in FIGS. 1 and 2, the visual information assisting apparatus 10 includes a CCD camera 24 as an imaging unit, a display 26 as a display unit, and a mirror structure 28 as a reflecting member. A CCD camera 24, a display 26 as a display means, and a mirror structure 28 as a reflecting member are provided in a pair on the left and right. In the following description, when the left and right CCD cameras 24, the display 26, and the mirror structure 28 are described separately, “R” is added to the end of the reference sign for the right one, and “L” is added to the end of the reference sign for the left one. ".

  The right CCD camera 24R is provided so that the imaging direction is aligned with the line-of-sight direction Dgr from the driver D to the right front pillar 22 side in a plan view, and images a right diagonally forward area with respect to the cabin C. . The left CCD camera 24L is provided in the plan view so as to match the imaging direction with the line-of-sight direction Dgl from the driver D to the left front pillar 22 side, and images a diagonally left front area with respect to the cabin C. . The left and right CCD cameras 24 are, for example, disposed in the door mirror device 32 on the corresponding side.

  The right display 26R receives image information from the CCD camera 24R wirelessly or by wire, and displays an image based on the image information. The left display 26L receives image information from the CCD camera 24L wirelessly or by wire, and displays an image based on the image information. In this embodiment, the left and right displays 26 </ b> R and 26 </ b> L are installed along the roof surface (the inner surface of the passenger compartment) at the rear portion of the roof 33 with respect to the upper end of the front pillar 22 on the corresponding side. In other words, the displays 26R and 26L have their display surfaces facing substantially downward.

  The right mirror structure 28R is provided on the surface of the right front pillar 22 (pillar garnish not shown) along the front pillar 22 (longitudinal direction), and the image displayed on the display 26R is directed toward the driver D. It is designed to reflect. Thereby, the driver D is configured to be able to visually recognize the image captured by the CCD camera 24R as a virtual image. The detailed structure of the mirror structure 28R and the mirror structure 28L will be described later.

  In this embodiment, the display 26R and the mirror structure 28R constitute a projection device 30 (right projection device 30R) as projection means. The projection device 30R projects the image captured by the CCD camera 24R so as to be visually recognized by the driver D as a virtual image located on the vehicle outer side (back side as viewed from the driver D) than the front pillar 22. It is said that.

  Specifically, as shown in FIG. 3, the projection device 30 is configured such that the distance L1 from the display 26R to the mirror structure 28R and the distance from the mirror structure 28R to the driver D coincide with the sum of L2 In this configuration, the viewing distance Lr from the person D to the virtual image Vir is set. In this embodiment, the viewing distance Lr is a viewing distance to a virtual image Vi that is reflected by a reflecting surface 34D described later in the mirror structure 28 and is visually recognized by the driver D.

  The display 26R and the mirror structure 28R are arranged such that the viewing distance Lr along the line-of-sight direction Dgr is sufficiently longer than the distance between the driver D and the right front pillar 22. Thereby, the virtual image Vir is visually recognized by the driver D as an image located at the position Pr outside the vehicle.

  Similarly, the left display 26L and the mirror structure 28L constitute a left projection device 30L (projection device 30). That is, the left mirror structure 28L is provided along the front pillar 22 (longitudinal direction) on the surface of the left front pillar 22 (pillar garnish not shown), and the image displayed on the display 26L is displayed to the driver D. Reflected toward. Thereby, the driver D is configured to be able to visually recognize the image captured by the CCD camera 24L as a virtual image Vil.

  Specifically, the projection device 30L has a distance that matches the sum of the distance L3 from the display 26L to the mirror structure 28L (reflecting surface 34D described later) and the distance L4 from the mirror structure 28L to the driver D. In this configuration, the viewing distance Ll from the driver D to the virtual image Vil is set. The display 26L and the mirror structure 28L are arranged such that the viewing distance Ll along the viewing direction Dgl is longer than the distance between the driver D and the left front pillar 22. As a result, the virtual image Vil is visually recognized by the driver D as an image located at the position Pl outside the vehicle.

  In this embodiment, the viewing distances Ll and Lr from the driver D to the virtual images Vil and Vir by the left and right projection devices 30L and 30R are both 1.5 m or more. This viewing distance will be supplemented later.

  In the following description, the left and right virtual images Vir and Vil and the viewing distances Lr and Ll will be referred to as the virtual image Vi and the viewing distance L when they are not distinguished from each other.

[Detailed structure of mirror structure]
As schematically shown in FIG. 4A, the mirror structure 28 includes a plurality of reflecting surfaces 34. 4A and 4B, a mirror structure 28 having four reflecting surfaces 34A, 34B, 34C, and 34D is shown for convenience of explanation. Further, as shown in FIG. 4A, it is assumed that the display area of the display 26 is divided into four in the front-rear direction. The four display areas are referred to as display areas 26A, 26B, 26C, and 26D in order from the front.

  The reflecting surface 34 </ b> A is formed at an angle that reflects the image displayed by the display area 26 </ b> A toward the eyes E of the driver D in the mirror structure 28 provided along the front pillar 22. Similarly, the reflecting surfaces 34B, 34C, 34D reflect the images displayed by the display areas 26B, 26C, 26D toward the eye E of the driver D in the mirror structure 28 provided along the front pillar 22. It is formed at an angle. The angles of the reflecting surfaces 34 (for example, the angles formed with respect to the vehicle vertical direction) are different from each other.

  Thereby, the mirror structure 28 is configured to allow the driver D to visually recognize the display images of the display areas 26 </ b> A to 26 </ b> D of the display 26 by the reflecting surfaces 34 </ b> A to 34 </ b> D that are arranged differently in the longitudinal direction of the front pillar 22. ing.

  The mirror structure 28 described above has a connecting portion 36 that connects adjacent reflecting surfaces 34 as shown in FIG. 4B. In other words, the mirror structure 28 includes a composite reflection portion in which the reflection surface 34 and the coupling portion 36 (non-reflection surface) are alternately arranged in the longitudinal direction of the front pillar 22 (in this embodiment, the composite reflection portion). As configured). In the above description, in order to facilitate understanding, an example in which the mirror structure 28 has four reflecting surfaces 34A to 34D is used. However, as shown in FIG. The plurality of reflecting surfaces 34 and connecting portions 36 are formed.

[Optical member]
Further, the projection device 30 of the visual information auxiliary device 10 includes an optical member 38 as image size adjusting means. The optical member 38 is configured to adjust a difference in size of each part of the virtual image Vi visually recognized by the driver D caused by a difference in viewing distance L that differs for each reflecting surface 34.

  In the structure shown in FIG. 4A, the viewing distance in which the sum of the distance from the display area 26D to the reflecting surface 34D and the distance from the reflecting surface 34D to the eyes E of the driver D is 1.5 m or more. L. The optical member 38 includes a plurality of lens bodies 40 (lenses) that enlarge the image so as to coincide with the viewing distance L to the virtual image Vi that is reflected by the reflecting surfaces 34A, 34B, and 34C and is visually recognized by the driver D. Body 40A-40C).

  In the lens body 40A, the sum of the distance from the display area 26A to the reflecting surface 34A and the correction distance obtained by multiplying the distance from the reflecting surface 34A to the eyes E of the driver D by the magnification factor X is matched with the viewing distance L. As described above, the optical magnification X of the image is set. Similarly, in the lens body 40B, the sum of the distance from the display area 26B to the reflecting surface 34B and the correction distance obtained by multiplying the distance from the reflecting surface 34B to the eyes E of the driver D by the magnification factor Y matches the viewing distance L. As described above, the optical magnification Y of the image is set. Further, in the lens body 40C, the sum of the distance from the display area 26C to the reflecting surface 34C and the correction distance obtained by multiplying the distance from the reflecting surface 34C to the eye E of the driver D by the magnification factor Z coincides with the viewing distance L. As described above, an optical magnification factor Z of the image is set.

  The optical member 38 described above has a connecting portion 42 that connects adjacent lens bodies 40 as shown in FIG. In other words, the optical member 38 includes a compound lens unit in which the lens body 40 and the connecting portion 42 (non-reflective surface) are alternately arranged in the longitudinal direction of the front pillar 22 (in this embodiment, the compound lens unit). As configured).

  In the above description, an example in which the optical member 38 has three lens bodies 40A to 40C is used for easy understanding. However, as shown in FIG. A plurality of lens bodies 40 and connecting portions 42 are formed. Thus, the optical member 38 in which each lens body 40 is miniaturized is fixed to the front pillar 22 (via the mirror structure 28) together with the mirror structure 28 in which each reflecting surface 34 is miniaturized. In this embodiment, the optical member 38 is integrated with the mirror structure 28 before being assembled to the front pillar 22, and individual optical axis adjustment is not required when assembled to the front pillar 22. Yes.

[Action]
Next, the operation of the embodiment will be described. Also in the following description, the left and right virtual images Vir and Vil and the viewing distances Lr and Ll will be referred to as the virtual image Vi and the viewing distance L when not described.

  First, the driver D of the automobile V to which the visual information assisting device 10 is applied drives the automobile V while confirming safety based on visual information visually recognized through the windshield glass 16 and the left and right side window glasses 20. .

  Further, the visual information assisting device 10 projects an image captured by the left and right CCD cameras 24 by the projecting device 30 and causes the driver D to visually recognize the virtual image Vi positioned on the outside of the vehicle obliquely forward with respect to the front pillar 22. That is, the vehicle exterior real scene (visual information) in the area that becomes a blind spot by the front pillar 22 is projected as a virtual image Vi by the mirror structure 28 provided on the front pillar 22, so that the driver D can confirm the direction to be confirmed (the blind spot area). ), And an image that supplements the blind spot area can be viewed. Thereby, for example, when the pedestrian W is present in the vehicle outside region that becomes a blind spot as shown in FIG. 1, the driver can notice the pedestrian W.

  For example, in the comparative example in which the driver D visually recognizes the image displayed on the screen of the display arranged along the front pillar 22, the viewing distance from the driver D to the display image is from the driver D of the present embodiment. The distance L2 is approximately the same as the distance L2 to the mirror structure 28. Therefore, in this comparative example, the distance between the viewing distance to the actual outside scene (for example, 2 m) and the viewing distance to the display image is large, and the driver D displays the display image when the line of sight changes from the actual outside scene to the display image. It is necessary to focus on (adjust) the driver D, and the driver D is likely to feel uncomfortable.

  On the other hand, in the visual information assisting apparatus 10 according to the present embodiment, an image captured by the CCD camera 24 is visually recognized by the driver D as a virtual image Vi located outside the vehicle. For this reason, compared with the comparative example, the difference between the viewing distance to the actual scene outside the vehicle (for example, 2 m) and the viewing distance L to the virtual image Vi is small, and the driver D feels uncomfortable in the focus adjustment to the virtual image Vi. Hateful. In particular, since the viewing distance L from the driver D is set to 1.5 m or more, the time required for the driver D to adjust the focus on the virtual image Vi is short. For example, it has been confirmed that even a driver who is 45 years old or older can adjust the focus on the virtual image Vi with little time when the line of sight is shifted from the outside scene to the virtual image Vi. In other words, the driver D can focus (simultaneously) on both the real scene outside the vehicle and the virtual image Vi, and the driver D compares the virtual image with the configuration in which the viewing distance L is less than 1.5 m. The uncomfortable feeling when visually recognizing Vi is suppressed.

  Here, in the visual information auxiliary device 10, since the mirror structure 28 has a plurality of reflecting surfaces (for example, reflecting surfaces 34 </ b> A to 34 </ b> D), the arrangement of the display 26 with respect to the mirror structure 28 arranged along the front pillar 22. There are few restrictions on (posture). For example, in the comparative example in which the mirror structure has a single reflecting surface, the display and the mirror structure are arranged along the vertical direction (substantially parallel to each other) in order for the driver D to visually recognize the virtual image Vi in the blind spot direction. Restrictions occur. Further, in the comparative example in which the image of the camera outside the vehicle is irradiated by the projector toward the retroreflective surface formed on the pillar, there is a restriction that the projector is disposed at a position close to the eyes of the driver.

  On the other hand, in the visual information assisting device 10, for each display region (for example, 26 </ b> A to 26 </ b> D) of the display 26, different reflective surfaces of the mirror structure 28 reflect the display image toward the driver D. For this reason, in the configuration in which the mirror structure 28 is disposed along the front pillar 22, the display image of the display means is reflected toward the driver D by setting the reflection angle of each reflection surface (for example, the reflection surfaces 34 </ b> A to 34 </ b> D). can do. That is, in the configuration in which the mirror structure 28 is provided on the front pillar 22, the degree of freedom of arrangement of the display 26 can be ensured.

  Further, the mirror structure 28 is configured as one member including a composite reflection surface in which the reflection surface 34 and the connecting portion 36 (non-reflection surface) are alternately arranged in the longitudinal direction of the front pillar 22. For this reason, the mirror structure 28 can be clearly provided along the inner surface of the front pillar 22 (garnish). Moreover, in this embodiment, the display 26 is disposed on the roof 33 in the configuration in which the mirror structure 28 is provided on the front pillar 22. For this reason, it is suppressed that the mirror structure 28 and the display 26 occupy vehicle interior space.

  Here, the visual information assisting apparatus 10 includes an optical member 38 that adjusts (corrects) the difference in viewing distance between the reflecting surfaces 34. For this reason, regarding the virtual image Vi that is an aggregate of images displayed in each display area of the display 26 and is visually recognized by the driver, the size difference between the portions is eliminated or suppressed to a small value. Accordingly, in a configuration in which the display 26 is arranged with respect to the mirror structure 28 so that the viewing distance from the display area of the display 26 to the eye E is different for each reflection surface 34 of the mirror structure 28, the driving is performed along with the visual recognition of the virtual image Vi. The uncomfortable feeling given to the person D can be suppressed.

  In addition, the visual distance difference of each reflecting surface 34 can be adjusted with a simple configuration using the optical member 38 having a plurality of lens bodies 40 corresponding to the plurality of reflecting surfaces 34. In addition, since the optical member 38 is configured as a compound lens portion in which the lens body 40 and the connecting portion 42 are alternately arranged in the longitudinal direction of the front pillar 22, the optical member 38 is configured as a mirror structure 28 (front pillar 22). It can be provided clearly along.

  In the above-described embodiment, an example in which the optical member 38 does not include the lens body 40 corresponding to the reflecting surface 34D has been described. However, the present invention is not limited thereto, and the lens body 40 corresponding to the reflecting surface 34D is provided. It is good also as a structure. For example, by setting the magnification factor of the lens body 40 corresponding to the reflecting surface 34D, the corrected viewing distance, which is the sum of the correction distance obtained by multiplying the magnification L by the distance L2 and the distance L1, is 1.5 m. It is good also as a structure made into the above. In this case, the enlargement factor of each of the lens bodies 40A to 40C is an enlargement factor obtained by multiplying the enlargement factor X to Z by the enlargement factor of the lens body 40 corresponding to the reflecting surface 34D.

<Modification of image size adjusting means>
In the above-described embodiment, the example in which the optical member 38 is provided as the image size adjusting unit has been described, but the present invention is not limited to this. For example, instead of the display 26, a display 50 that also serves as an image size adjusting unit may be provided as shown in FIG.

  FIG. 5A shows a display screen on the display 26. In the display 26, the image display magnification of each of the display areas 26A to 26D is constant. On the other hand, in the display 50, the display magnification is varied for each of the display areas 50A to 50D as shown in FIG. Due to the difference in display magnification, the visual distance difference is corrected, and the virtual image Vi visually recognized by the driver D is eliminated or kept small.

<Other variations>
In each of the above-described embodiments, the examples in which the displays 26 and 50 are provided on the roof 33 (the roof trim) that is the inner surface of the vehicle are shown, but the present invention is not limited to this. For example, the displays 26 and 50 may be arranged inside an interior material such as an instrument panel.

  Further, in each of the above-described embodiments, the example of assisting the visual information of the blind spot area by the front pillar 22 as the virtual image Vi is shown, but the present invention is not limited to this, and the blind spot area by the vehicle component of the driver D is shown. Any visual information may be used as long as it is visual information. Therefore, for example, a configuration may be used in which an area outside the vehicle (or outside the cabin C) that becomes a blind spot is captured by a fender, a front hood, or the like, and the captured image is projected onto a mirror structure provided on the surface of the instrument panel. In this case, the virtual image Vi visually recognized by the driver D only needs to be visually recognized so as to be positioned on the vehicle outer side (back side as viewed from the driver D) with respect to the vehicle components such as the instrument panel, for example, in the engine compartment. May be projected (at a viewing distance). Further, for example, a configuration may be adopted in which visual information of the rear (during reverse) that becomes a blind spot is captured by a rear seat back, rear pillar, rear fender, rear door or the like and projected onto a mirror structure provided on the rear pillar or the like.

  Further, in each of the above-described embodiments, the example in which the CCD camera 24 is used as the imaging unit has been described. However, the present invention is not limited to this, and any imaging unit may be used. Therefore, for example, a CMOS camera or the like may be used instead of the CCD camera 24.

  Furthermore, in each of the above-described embodiments, an example in which the left and right CCD cameras 24 and the projection device 30 are provided has been described, but the present invention is not limited to this. For example, the CCD camera 24 and the projection device 30 may be provided on either the left or right side.

  In addition, it goes without saying that the present invention can be implemented with various modifications without departing from the gist thereof. For example, you may employ | adopt the structure which combined suitably the characteristic structure of each embodiment and the modification.
