Description

  The present invention relates to a vehicle visual assistance device that makes it easy for a driver to recognize the vehicle width, front end position, or rear end position of a vehicle.

Conventionally, when the driver aligns the reference line related to the end of the vehicle (for example, the front end) with the target line on the ground (stop line or white line of the parking lot), etc., The driver arbitrarily sets a guideline (mark) that matches the reference line from the viewpoint, and matches the target line with the guideline (mark).
However, in this case, the reference line did not readily match the target line due to a difference in the viewpoint of the subject, an error (individual difference) that determined that the target (mark) matched the target line, and the like.

There is known a vehicular visual assistance device that assists a driver to align a reference line with such a target line (see, for example, Patent Document 1).
JP 2005-14720 A

The vehicle visual assistance device of Patent Document 1 includes a first mark portion on the door mirror, a second mark portion on the front bumper, and a virtual extension line connecting these first and second mark portions. The first and second mark portions are set so that the intersection intersecting the ground is the front end position of the vehicle.
Thus, the driver can recognize the front end position of the vehicle by viewing the first and second mark portions in an overlapping manner.

However, in the vehicle visual assistance device, the door mirror provided outside the vehicle and the first and second mark portions provided on the front bumper need to be simultaneously put into the field of view. It was necessary to recognize it after opening the head and taking the head out of the car.
In this case, the head may get wet on a rainy day or the like, and it is necessary to move from a normal driving posture. Therefore, it is more preferable if the front end of the vehicle can be recognized in the normal driving posture.

  In the vehicular visual aid device, the intersection where the virtual extension line connecting the first and second mark portions intersects the ground and the first and second mark portions are all captured as points. Therefore, although one point at the front end of the vehicle can be adjusted with respect to the vehicle width direction, it can be adjusted to a line outside the vehicle width, such as a line in the vehicle width direction passing through the front end of the vehicle (such as a parking line indicating line). There was a risk of parking the vehicle diagonally. Therefore, if it can be matched with the line outside the vehicle width, the convenience is further improved.

  The present invention can recognize a vehicle body part such as the front end of the vehicle body while maintaining a normal driving posture, and can improve convenience when the vehicle body part such as the vehicle front end is aligned with a target line such as a stop line. It is an object to provide a visual assistance device for a vehicle.

  The invention according to claim 1 is a recognition line for aligning a reference line on which a vehicle body part of a vehicle or a line separated from the vehicle body part by a predetermined distance is projected on a flat surface with a target line previously drawn on a flat ground surface. A vehicle visual assistance device for assisting the driver to align the reference line with the target line, wherein the recognition line is in a plane including the driver's line of sight and the reference line, and includes a vehicle compartment. On the curved surface of the vehicle body or on at least two different surfaces of the vehicle body including the passenger compartment, and when the driver's eye point is set to a predetermined position, it is recognized as a straight line and keeps the eye point in a predetermined state. In this state, the recognition line and the target line are aligned with each other.

  The invention according to claim 2 is characterized in that the two different surfaces have different normal directions.

  The invention according to claim 3 is characterized in that a recognition assisting graphic for assisting the recognition that the eye point is at a predetermined position is provided around the recognition line.

  The invention according to claim 4 is characterized in that a projection device is provided in the passenger compartment, and a recognition line is projected by the projection device.

  The invention according to claim 5 is characterized in that the recognition line is projected by the projection device when the vehicle falls below a predetermined vehicle speed.

  In the invention according to claim 6, the recognition line is visually recognized through the vehicle mirror, and the recognition line includes an extension line in which the extension of the reference line is drawn on the rear window of the vehicle body, and a frame of the rear window. It is characterized in that it is composed of an extension line and an auxiliary line visually recognized in a straight line when drawn at a predetermined eye point.

  The invention according to claim 7 is characterized in that the extension line is formed by a heat ray provided in the rear window.

In the invention according to claim 1, the vehicular visual aid device is an object in which a reference line on which a vehicle body part of a vehicle or a line away from the vehicle body part by a predetermined distance is projected on a plane is drawn on a flat ground surface in advance. A recognition line is provided to match the line, and assists the driver when aligning a vehicle body part (reference line) such as the front end of the vehicle body with a target line such as a stop line.
The recognition lines are provided in a plane including the driver's line of sight and the reference line, and on a curved surface of the vehicle body including the passenger compartment or on at least two different surfaces of the vehicle body including the passenger compartment. Therefore, since the recognition line is recognized in a straight line when the driver's viewpoint is set at a predetermined position, the driver's viewpoint is adjusted to the predetermined position regardless of the driver's physique. Can do.
When the driver's eye point is set at a predetermined position, it is recognized in a straight line, and the recognition line and the target line are aligned with each other while keeping the eye point in a predetermined state. Can align a reference line such as the front end of the vehicle body that cannot be recognized from the driver's seat with a target line such as a stop line. As a result, it is possible to recognize the front end of the vehicle body, which the driver has determined sensuously, while maintaining the driving posture from the driver's seat, and to improve the convenience of the driver.
Further, since the recognition line is only provided on the plane including the driver's line of sight and the reference line and on the curved surface of the vehicle body including the passenger compartment or on at least two different surfaces of the vehicle body including the passenger compartment, for example, a camera Compared to the case where the vehicle body part is recognized using a display, the vehicle body part can be known with a simple configuration.

  In the invention according to claim 2, since the normal directions of two different surfaces are different, if the position of the eye point or the angle of the line of sight for viewing the two surfaces is different, the recognition line is bent and recognized. This makes it easier to grasp the position of the eye point (viewpoint).

  In the invention according to claim 3, a recognition assisting graphic is provided around the recognition line to assist in recognizing that the eye point is at a predetermined position. If the position of the eye point (viewpoint) is not appropriate, the recognition assisting graphic appears to be distorted, so that it becomes easier to grasp the position of the predetermined eye point (viewpoint).

  In the invention according to claim 4, since the projection device is provided in the vehicle interior and the recognition line is projected by the projection device, the recognition line can be drawn only when necessary, so the recognition line is unnecessary. The appearance of the passenger compartment in the case can be improved.

  In the invention according to claim 5, since the recognition line is projected by the projection device from when the vehicle falls below the predetermined vehicle speed, the convenience during the stop operation of the vehicle can be maintained, and at the time of normal traveling A recognition line that is not used can be erased, and comfort in the passenger compartment is improved. Furthermore, since it is sufficient to supply power to the projection apparatus only when a recognition line is required, energy supply can be reduced (energy saving).

In the invention which concerns on Claim 6, since a recognition line is visually recognized through the vehicle mirror of a vehicle, object lines, such as the road shoulder of a road visually recognized with a vehicle mirror, are recognized to the recognition line visually recognized with a vehicle mirror. If you match it, you can justify it. That is, the convenience of the driver can be improved.
The recognition line includes an extension line in which the extension of the reference line is drawn on the rear window of the vehicle body, and an auxiliary line that is drawn on the lower surface of the frame body of the rear window and is visually recognized in a straight line with the extension line at a predetermined eye point. Thus, the driver can grasp the position of the predetermined eye point.

  In the invention according to claim 7, since the extension line is formed by the heat ray provided in the rear window, it is not necessary to provide a separate recognition line, and the structure can be simplified. As a result, the cost of the vehicle visual assistance device can be reduced.

The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. The drawings are viewed in the direction of the reference numerals.
FIG. 1 is a side view of a vehicle that employs a vehicle visual assistance device according to the present invention, FIG. 2 is a plan view of the vehicle shown in FIG. 1, and FIG. 3 is a diagram of a first embodiment according to the present invention. It is a perspective view of the visual recognition auxiliary device for vehicles.

As shown in FIGS. 1 to 3, the vehicle 10 is provided in the vehicle body 11 so as to be freely opened and closed, and is provided in the vehicle compartment 12 with a right front door 14 on which a driver 28 gets on and off. An instrument panel 16 that covers the air conditioner air outlet 15 and a reference line 21 on which a vehicle body part (vehicle body front end) 17 is projected on a plane is drawn on a flat ground 24 in advance. The vehicle visual assistance device 30 is provided to match the target line 23.
The right front door 14 includes a door trim 19 that covers the inside of the passenger compartment 12.

Specifically, the reference line 21 is a line that is projected on a plane through a vehicle body part (vehicle body front end) 17 and extending in the vehicle width direction.
Specifically, the target line 23 is a line drawn on the ground 24 in advance including a stop line, a line drawn to a parking lot, a curb, a wall, or the like.

  The vehicular visual assist device 30 is a device that guides the eye drop 28 a of the driver 28 to a predetermined position and assists the driver 28 in aligning the reference line 21 with the target line 23, and the upper inclined surface 25 of the door trim 19. A first recognition line 31 provided on the door trim 19, a second recognition line 32 provided on the vertical surface 26 of the door trim 19 and continuously provided on the first recognition line 31, and an end of the instrument panel 16. And a third recognition line 33 provided on the slope 27.

The upper end inclined surface 25 and the vertical surface 26 are examples of at least two different surfaces of the vehicle body 11 including the vehicle compartment 12 and have different normal directions. The end slope 27 is one of the curved surfaces of the vehicle body 11 including the vehicle compartment 12.
The 1st-3rd recognition lines 31-33 contain what was formed by painting, a design shape, or a light-emitting body.

  The first to third recognition lines 31 to 33 are provided in a plane S1 including (passing) the line of sight 29 of the driver 28 and the reference line 21, and the position of the eye point 28a of the driver 28 is set in the longitudinal direction of the vehicle body. It is provided so that it is recognized in a straight line when it is aligned with the vehicle body width direction and the vehicle body height direction.

  That is, when the eye point 28a of the driver 28 is out of the plane S1 (when the line of sight 29 is shifted), the relationship between the first to third recognition lines 31 to 33 appears to be other than a straight line. However, even if the first to third recognition lines 31 to 33 are within the plane S1 including (passing through) the line of sight 29 and the reference line 21 of the driver 28, a single plane of the vehicle body 11 including the passenger compartment 12 is included. Since the relationship between the first to third recognition lines 31 to 33 remains a straight line, the driver 28 cannot notice the shift of the eye point 28a. Accordingly, the first to third recognition lines 31 to 33 need to be provided on the curved surface or at least two different surfaces.

4 (a) to 4 (c) are explanatory views showing how to use the vehicle visual assistance device shown in FIG.
In (a), the visual assistance apparatus 30 for vehicles when the eye point 28a shown in FIG. 1 is shifted (the line of sight 29 is shifted) is shown, and the first to third recognition lines 31 to 33 are shown. The relationship is visible by turning.

  In (b), the driver 28 (see FIG. 1) moves the eye point 28a in the longitudinal direction of the vehicle body, in the vehicle body width direction and in the vehicle body height direction, and the first to third recognition lines 31 to 33 are straight lines. To a position where it can be recognized.

  In (c), the vehicle 10 (see FIG. 1) is moved forward with the eye point 28a set at a predetermined position, and the first to third recognition lines 31 to 33 are aligned with the target line (stop line) 23. . Thereby, the vehicle body part (vehicle body front end) 17 shown in FIG. 2 can be aligned with the target line (stop line) 23.

  As shown in FIGS. 1 to 4, the vehicular visual recognition assisting device 30 flatly displays a reference line 21 in which a vehicle body part of the vehicle 10 or a line separated from the vehicle body part by a predetermined distance is projected on a plane. The recognition lines 31 to 33 for adjusting to the target line 23 drawn on the ground 24 are provided, and the driver 28 adjusts the vehicle body part (reference line 21) such as the front end 17 of the vehicle body to the target line 23 such as the stop line. It is to assist.

  At least two different surfaces 25 of the vehicle body 11 including the vehicle compartment 12 on the curved surface 27 of the vehicle body 11 including the vehicle compartment 12 in the plane S1 including (passing) the line of sight 29 of the driver 28 and the reference line 21; 26, recognition lines 31 to 33 are provided. Accordingly, the recognition lines 31 to 33 are recognized in a straight line when the eye point (viewpoint) of the driver 28 is set at a predetermined position (on the plane S1). Regardless, the eye point (viewpoint) of the driver 28 can be adjusted to a predetermined position.

  When the eye point 28a of the driver 28 is set at a predetermined position, it is recognized as a straight line, and the recognition lines 31 to 33 and the target line 23 are aligned with each other with the eye point 28a kept in a predetermined state. Therefore, the reference line 21 such as the front end 17 of the vehicle body that cannot be generally recognized from the driver's seat can be matched with the target line 23 such as the stop line. As a result, the vehicle body front end 17 or the like that the driver 28 has sensuously determined can be recognized from the driver seat 18 while maintaining the driving posture, and the convenience of the driver 28 can be improved.

  Further, at least two different surfaces of the vehicle body 11 including the vehicle compartment 12 within the plane S1 including (passing through) the line of sight 29 and the reference line 21 of the driver 28 and on the curved surface 27 of the vehicle body 11 including the vehicle interior 12. Since only the recognition lines 31 to 33 are provided on 25 and 26, for example, the vehicle body part can be known with a simple configuration as compared with the case where the vehicle body part is recognized using a camera or a display.

  Since the normal direction is different between the upper inclined surface 25 and the vertical surface 26 which are two different surfaces, the recognition lines 31 to 33 are bent if the position of the eye point 28a for visually recognizing the two surfaces or the angle of the line of sight 29 is different. Therefore, it becomes easy to grasp the position of the predetermined eye point (viewpoint) 28a.

FIG. 5 is a perspective view of the vehicular visual assistance device of the second embodiment according to the present invention. The same parts as those used in the vehicular visual assistance device (FIGS. 1 to 3) of the first embodiment are denoted by the same reference numerals. Detailed description will be omitted.

  The first to third recognition lines 41 to 43 are provided so as to have a line width that is visually recognized to be substantially the same width as the target line 23 when viewed from the eye point 28a (see FIG. 1). In general, the target line (white line) 23 such as a stop line is formed with a certain width (for example, 15 cm), so that it is visually recognized with substantially the same width as the target line 23 when viewed from the eye point 28a. By providing the line width, it is easy to intuitively match the target line (white line such as a stop line) 23 drawn on the ground (road) 24.

FIG. 6 is a perspective view of the vehicular visual aid device of the third embodiment according to the present invention. The same parts as those used in the vehicular visual aid device (FIGS. 1 to 3) of the first embodiment are denoted by the same reference numerals. Detailed description will be omitted.

And a recognition assisting figure 54 for assisting in recognition of the position.

  The recognition assisting graphic 54 is a circle composed of one semicircular portion 55 provided on the vertical surface 26 of the door trim 19 and the other semicircular portion 56 provided on the end slope 27 of the instrument panel 16. It is recognized as a perfect circle when 28a is at a predetermined position, and is distorted when the eye point 28a is out of the predetermined position.

  In the vehicular visual assistance device 50 of the third embodiment, a recognition assist graphic 54 is provided around the recognition lines 51 to 53 to assist in recognizing that the eye point 28a is at a predetermined position. If the position of the eye point (viewpoint) 28a is not appropriate, the recognition assisting figure 54 appears distorted, making it easier to grasp the position of the predetermined eye point (viewpoint) 28a. That is, it becomes easier to guide the eyes of the driver 28 to the position of the predetermined eye point 28a than only the first to third recognition lines (line segments) 51 to 53.

  FIG. 7 is a perspective view of the vehicle visual assistance device of the fourth embodiment according to the present invention. The same parts as those used in the vehicle visual assistance device (FIGS. 1 to 3) of the first embodiment are denoted by the same reference numerals. Detailed description will be omitted. FIG. 8 is a principle diagram of the vehicular visual assistance device shown in FIG. 7, and FIGS. 9A and 9B are explanatory views of the operation of the vehicular visual assistance device shown in FIG.

  As shown in FIG. 7, the vehicle visual assistance device 60 of the fourth embodiment is provided on the first recognition line 61 provided on the upper end inclined surface 25 of the door trim 19 and on the vertical surface 26 of the door trim 19.

And a recognition assisting figure 64 that assists in recognizing that the eye point 28a (see FIG. 1) is at a predetermined position.

  The recognition assisting figure 64 is composed of one half vehicle body view 65 provided on the vertical surface 26 of the door trim 19 and the other half vehicle body view 66 provided on the end slope 27 of the instrument panel 16. 26 and an end slope 27, and as shown in FIG. 8, it can be recognized as a meaningful shape when viewed from a specific direction.

  FIG. 9A shows how the recognition assisting figure (vehicle diagram) 64 is recognized when the correct eye point 28a (see FIG. 1) is set. The positional relationship with the vehicle body 11 can be recognized more intuitively. In addition, since the recognition assisting figure 64 is a vehicle body diagram, for example, the driver 28 can recognize that the vehicle 28 is a device for aligning the position of the front end 17 of the vehicle body without the instruction manual for the vehicle 10.

  FIG. 9B shows how the recognition assisting figure (vehicle diagram) 64 is recognized when it is set to the shifted eye point 28a (see FIG. 1). The recognition assisting figure 64 is provided over the vertical surface 26 and the end slope 27, and the normal direction of the vertical surface 26 of the door trim 19 and the end slope 27 of the instrument panel 16 are different. If they are shifted, one half car body diagram 65 and the other half car body diagram 66 are not recognized as continuous correct figures. Therefore, it becomes easy to guide the driver's 28 (see FIG. 1) eyes to the position of the predetermined eye point 28a.

FIG. 10 is a perspective view of the vehicular visual assistance device of the fifth embodiment according to the present invention. The same parts as those used in the vehicular visual assistance device (FIGS. 1 to 3) of the first embodiment are denoted by the same reference numerals. Detailed description will be omitted.

A second front recognition line 72a and a second rear recognition line 72b provided on the vertical surface 26 of the door trim 19 and continuously drawn on the first front recognition line 71a and the first rear recognition line 71b, respectively; Around the third front recognition line 73a and the third rear recognition line 73b provided on the end slope 27 of the instrument panel 16 and the recognition lines 71a to 73a and 71b to 73b, an eye point 28a is located at a predetermined position. It is comprised from the recognition assistance figure 74 which assists recognition of being.

  The recognition assisting graphic 74 includes a second front recognition line 72a and a second rear recognition line 72b, one lattice portion 75 provided on the vertical surface 26 of the door trim 19, the third front recognition line 73a, and the second rear recognition line 72b. 3 is a lattice figure including the other rear recognition line 73b and the other lattice portion 76 provided on the end slope 27 of the instrument panel 16, and is recognized by the lattice when the eye point 28a is at a predetermined position. When the eye point 28a deviates from a predetermined position, it is recognized as distorted. Therefore, the driver's 28 eyes can be easily guided to the position of the predetermined eye point 28a.

FIG. 11 is a perspective view of the vehicle visual assistance device of the sixth embodiment according to the present invention. The same parts as those used in the vehicle visual assistance device (FIGS. 1 to 3) of the first embodiment are denoted by the same reference numerals. Detailed description will be omitted.
The vehicle visual assistance device 80 of the sixth embodiment is provided on the first recognition line 81 provided on the upper end inclined surface 25 of the door trim 19 and on the vertical surface 26 of the door trim 19 and is continuous with the first recognition line 81. The eye point 28a is located at a predetermined position around the second recognition line 82 drawn in the drawing, the third recognition line 83 provided on the end slope 27 of the instrument panel 16, and the recognition lines 81-83. It is comprised from the recognition assistance figure 84 which assists recognition of being.

The recognition assisting graphic 84 includes a first circular graphic 85 provided across the upper end inclined surface 25 and the vertical surface 26, a second circular graphic 86 provided across the vertical surface 26 and the end slope 27, It comprises a third circular figure 87 provided on the end slope 27.
The first to third circular figures 85 to 87 are recognized as true circles when the eye point 28a is at a predetermined position, and are distorted and recognized when the eye point 28a is out of the predetermined position. Therefore, the driver's 28 eyes can be easily guided to the position of the predetermined eye point 28a.

That is, a plurality of figures having the same shape (first to third circular figures 85 to 87) are constituted by a door trim 19 having a plurality of faces (upper inclined face 25 and vertical face 26) or a curved face (end slope) 27. By drawing on an interior surface such as an instrument panel, the images have the same shape only when viewed from a specific eye point 28a.
By recognizing the difference in the appearance of the plurality of figures (first to third circular figures 85 to 87), it becomes easier to guide the eyes of the driver 28 to the predetermined eye point 28a.

  FIG. 12 is a side view of a vehicle employing the vehicular visual assistance device of the seventh embodiment according to the present invention, FIG. 13 is a plan view of the vehicle shown in FIG. 12, and FIG. 14 is related to the present invention. It is a perspective view of the visual auxiliary equipment for vehicles of the 7th example.

  As shown in FIGS. 12 to 14, the vehicle 100 is provided in the vehicle body 101 so as to be openable and closable, and is provided in the vehicle compartment 102 with a right front door 104 on which a driver 118 gets on and off. An instrument panel 106 that covers the air conditioner air outlet 105 and a first reference line 111 on which a vehicle body part (front end of the vehicle body) 107 is projected on a flat surface 114 is flattened in advance. The vehicle visual assistance device 120 is provided for each of the target lines 113 drawn above.

  The right front door 104 includes a door trim 109 that covers the inside of the passenger compartment 102. The right front door 104, the instrument panel 106, and the target line 113 are the same as the right front door 14, the instrument panel 16, and the target line 23 shown in FIGS.

  The vehicle visual assistance device 120 is a device that guides the driver 118's eyedropper 118a to a predetermined position and assists the driver 118 in aligning the first reference line 111 with the target line 113, respectively. Left and right projection devices (line projectors) 121 and 122 provided on the roof 102a of the passenger compartment 102 including the control unit 123 and the control unit 123 that controls the left and right projection devices 121 and 122.

  The left projection device 121 includes an upper end inclined surface 115 of the door trim 109, a vertical surface 116 of the door trim 109, and an end portion of the instrument panel 106 in a plane S2 including the line of sight 119a of the driver 118 and the first reference line 111. This is a device for projecting the first recognition line 124 onto a surface including the inclined surface 117.

The right projection device 122 projects the first recognition line 124 in the same manner as the projection device 121. The reason for providing the two right and left projection devices is that there is a risk that the line may be interrupted by the driver 118 or the passenger's head of the passenger seat, steering, or the like. (If the line projector is arranged in the plane S2, one recognition line can be drawn on every surface. However, in this case, the head 118b of the driver 118 always blocks the light rays of the line projectors 121 and 122. Therefore, two left and right line projectors are arranged.)
The left and right projection devices 121 and 122 are disposed so as to avoid the head 118b of the driver 118.

  The first recognition line 124 is a line for aligning the reference line 111 with the target line 113 when the first reference line 111 is set at the front end (vehicle body part) 107 of the vehicle body. The upper edge inclined surface 115 of the door trim 109, the vertical surface 116 of the door trim 109, and the end slope 117 of the instrument panel 106 are set to predetermined eye points when viewed linearly. In this state, by aligning the first recognition line 124 with the target line 113, the vehicle front end 107 can be aligned with the target line 113.

  Here, instead of the first recognition line 124, the second recognition line 125 may be projected by the projection devices 121 and 122. The second recognition line 125 is a line for aligning the reference line 112 with the target line 113 when the second reference line 112 is set to the axle (vehicle body part) 108 of the front wheel 103. The second recognition line 125 is set to a predetermined eye point 118a when viewed in a straight line on the upper end inclined surface 115 of the door trim 109 and the vertical surface 116 of the door trim 109. In this state, the axle can be aligned with the target line 113 by aligning the second recognition line 125 with the target line 113.

Moreover, it is preferable that the left and right projection devices 121 and 122 project simultaneously.
