Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the front windshield described in Patent Document 1, since a small circular perception mark is disposed inside the concave portion formed in the border portion, a driver driving the vehicle tends to concentrate his / her attention on the perception mark surrounded by the concave portion. And in the case of a small circular perception mark, the awareness of the driver during driving to align the perception mark with the target tends to increase. nine In the case of, during driving, the driver's awareness to align the perception mark nine with the target tends to increase.

[0006] Therefore, the present invention aims to provide a vehicle front windshield that allows the driver to naturally and comfortably perceive the positional relationship between their vehicle and the road. Furthermore, the present invention contributes to energy efficiency in the field of vehicle safety technology. [Means for solving the problem]

[0007] A front windshield of a vehicle according to one aspect of the present invention comprises a windshield body and a perceptual guide positioned in the lower region of the windshield body to allow the driver to perceive the relative position of the vehicle to the outside world, wherein the perceptual guide has an upper edge extending substantially along the vehicle width direction, and the upper edge is provided such that when the upper edge coincides with the lane on the road surface visible to the driver, it becomes longer than the width of the lane in the vehicle width direction. Furthermore, the perception guide is positioned such that its center in the vehicle width direction is located in the center of the vehicle width direction, and the lane is the lane located on the left side of the vehicle when the driver's seat is located on the right side, and the lane located on the right side of the vehicle when the driver's seat is located on the left side. It is characterized by the following:

[0008] With the above configuration, the driver can operate the vehicle while recognizing the relative position of the sensory guide, such as the upper edge overlapping with or parallel to the lane markings on the road surface. This makes it easier to drive the vehicle while maintaining a nearly constant distance from the lane, thus suppressing deviations and swaying within the vehicle's lane and enabling stable driving. The length of the upper edge of the sensory guide is set to be longer than the width of the lane visible to the driver, so that the shape does not force the driver to stare at a single point on the sensory guide and aim at a target object with the steering wheel. The driver can drive stably while keeping the relative position of the sensory guide and the lane in their field of vision while driving as usual, so they will feel less fatigued.

[0009] The sensory guide may have side edges extending downward from both ends of the upper edge in the vehicle width direction, and these side edges may be inclined such that their length in the vehicle width direction gradually increases downward from the end of the upper edge.

[0010] In this case, when the lane markings on the road surface come into contact with the side edge of the perceptual guide while the vehicle is being driven, the change in height at the point where the side edge and the lane overlap makes it possible to intuitively grasp the amount of deviation from the reference area where the lane markings and the top edge of the perceptual guide overlap. Since the change in the amount of deviation that can be perceived while driving is linked to the change in the view seen through the passenger-side mirror, if this configuration is adopted, the driver can appropriately judge the direction and amount of steering correction by also looking at the passenger-side mirror.

[0011] The maximum length in the vehicle width direction of the side edges, which are positioned on both sides of the upper edge in the vehicle width direction, may be set to half the length of the upper edge.

[0012] In this case, the length in the vehicle width direction from the reference area where the top edge and the lane line overlap to the bottom edge of the side edge becomes half of the maximum adjustment range within the reference area (the length of the top edge in the vehicle width direction), making it easier for the driver to intuitively grasp the amount of deviation from the reference area. Furthermore, because the width of the two side edges positioned on either side of the top edge in the vehicle width direction is the same, the perceptual guide appears visually stable, making it less likely for the driver viewing the perceptual guide to feel any discomfort. Furthermore, because the length of the side edge that allows the driver to perceive the amount of deviation from the reference area (upper edge area) is sufficiently long (half the length of the maximum adjustment range within the reference area), drivers who are viewing the perceptual guide are less likely to feel the need to hastily align the upper edge of the perceptual guide with the lane markings. As a result, drivers can naturally correct the steering wheel while maintaining a natural view of the road ahead.

[0013] The height from the lower end to the upper end of the side edge may be set to be less than or equal to the maximum length of the side edge in the vehicle width direction.

[0014] In this case, the two side edges positioned on either side of the top edge in the vehicle width direction rise gently (not at an acute angle) towards the top edge, making it less likely for the driver viewing the perceptual guide to feel the need to hastily align the top edge of the perceptual guide with the lane markings. As a result, the driver can naturally correct the steering wheel while maintaining a natural view of the road ahead.

[0015] The aforementioned sensory guide may be positioned such that its center in the vehicle width direction coincides with the center of the vehicle in the vehicle width direction.

[0016] In this case, by visualizing the top edge of the sensory guide, the driver can recognize the center of their vehicle in the width direction from the center of the top edge. Therefore, the driver can operate the steering wheel while being aware of the center of their vehicle in the width direction. Furthermore, since the upper edge of the perception guide extends to the left and right by the same length from the center position in the vehicle's width direction, the lateral displacement of the vehicle can be adjusted within the same length range.

[0017] The perceptual guide may be positioned such that its upper edge is above the upper edge of the vehicle's front hood, as seen by the driver through the windshield body. Furthermore, "the upper edge of the vehicle's front hood as seen from the driver's perspective" refers to the upper edge of the vehicle's front hood as seen from the eye point of a standard-sized adult seated in the driver's seat.

[0018] If the upper edge of the perception guide overlaps with the front hood from the driver's perspective, the intersection of the upper edge and the lane markings on the road surface is obscured by the front hood. In contrast, in this configuration, the upper edge of the perception guide is positioned above the upper edge of the front hood, so the intersection of the upper edge and the lane markings on the road surface is not obscured by the front hood. Therefore, the driver can accurately grasp the positional relationship between the lane markings on the road surface and their own vehicle based on the overlapping position of the upper edge of the perception guide and the lane markings on the road surface. Also, when the vehicle's headlights are turned on, the road surface can be seen brightly illuminated through the windshield body. At this time, since the intersection of the upper side of the perception guide and the lane on the road surface is not blocked by the front hood portion, the driver can clearly recognize the positional relationship between the upper side and the brightly illuminated lane.

[0019] A bordering portion that borders the peripheral edge may be provided at the peripheral edge of the windshield body, and the perception guide may be provided so as to be continuous with the bordering portion.

[0020] In this case, since the perception guide and the bordering portion are provided continuously, the perception guide does not appear to float in the windshield body. Therefore, when this configuration is adopted, the driver will not feel a sense of discomfort as if a foreign object has adhered, and the comfort during vehicle operation can be improved.

Effect of the Invention

[0021] The front windshield of the vehicle according to the present invention is provided such that when the upper side of the perception guide overlaps with the lane on the road surface visible to the driver, the upper side is longer than the width of the lane in the vehicle width direction. This is for the consideration of the shape to prevent the driver from staring at the perception guide and to flexibly respond so as to be able to set a standard for stable driving for multiple road width specifications. For this reason, the driver can operate the steering wheel so that the lane is contained within the range of the upper side of the perception guide with a long length in the vehicle width direction at the driver's line of sight, or the lane is along the side portion of the upper side, etc., so that the positional relationship between the perception guide and the lane maintains a certain state. Therefore, when the front windshield of the vehicle of the present invention is adopted, the driver can naturally grasp the positional relationship between the own vehicle and the road without a sense of discomfort. Therefore, the front windshield of the vehicle according to the present invention can contribute to energy efficiency improvement in the field of vehicle safety technology.

Mode for Carrying Out the Invention

[0023] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, front and rear, up and down, and left and right mean front and rear, up and down, and left and right with respect to the vehicle 1 facing the forward direction.

[0024] FIG. 1 is a figure showing the forward field of view visible to the driver superimposed on a view of the vehicle 1 of the present embodiment seen from inside the vehicle cabin facing forward. In FIG. 1, 10 is a front windshield disposed in front of the driver's seat, 11 is a steering wheel disposed in front of the driver's seat, and 12L and 12R are left and right side mirrors. The front windshield 10 is formed in a horizontally long rectangular shape when viewed from the front.

[0025] The front windshield 10 comprises a windshield body 13 made of transparent tempered glass or the like, and a trim portion 14 made of black ceramic dots printed on the outer edge of the windshield body 13. The trim portion 14 is provided for the purpose of concealing the adhesive portion of the front windshield 10 to the vehicle body and for the purpose of blocking light. The trim portion 14 is provided on the lower edge 13L, the upper edge 13U, and the left and right side edges 13S of the windshield body 13. Furthermore, the edging portion 14 is not limited to being made of black ceramic dots. The material and installation method of the edging portion 14 are not restricted as long as it is located on the outer edge of the windshield body 13 and can obstruct a portion of the forward view from inside the vehicle.

[0026] A sensory guide 20 is provided at the center of the lower edge 13L (lower region) of the windshield body 13 in the vehicle width direction, allowing the driver to perceive the relative position of the vehicle 1 to the outside world. The sensory guide 20 is formed to connect with the border 14 of the lower edge 13L, for example, by the same method as the border 14 (for example, by printing black ceramic dots). However, the sensory guide 20 can also be provided on the windshield body 13 by a method different from that of the border 14.

[0027] Figure 2 shows the positional relationship between the perception guide 20 and the front hood portion 30 of the vehicle 1, and Figure 3 shows an example of how the perception guide 20 and the lane markings 40 on the road surface 39 appear. As shown in Figures 2 and 3, the sensory guide 20 of this embodiment is formed in an isosceles trapezoidal shape, with the upper edge 20U being shorter than the lower edge. The sensory guide 20 has an upper edge 20U that extends substantially along the vehicle width direction, and a pair of side edges 20S that extend downward from each left and right end of the upper edge 20U, inclined outward in the vehicle width direction. The lower end (lower edge) of the sensory guide 20 is connected to the upper surface of the edging portion 14 on the lower edge side.

[0028] In this embodiment, the upper edge 20U of the sensory guide 20 extends substantially horizontally in the vehicle width direction. However, the upper edge 20U does not necessarily have to be substantially horizontal; it may have a shape that is inclined in whole or in part, or a shape that has a non-straight section in part.

[0029] The length L1 of the upper edge 20U of the perceptual guide 20 is set to the following length: In other words, the length L1 of the upper edge 20U is set to be longer than the width w of the lane 40 in the vehicle width direction when the upper edge 20U overlaps with the lane 40 on the road surface 39 as seen by the driver, while the driver is seated in the driver's seat and looking at the road surface 39 ahead through the windshield body 13. In this embodiment, the length L1 of the upper edge 20U is set to be twice the width w of the lane 40 that overlaps with the upper edge 20U.

[0030] Here, the "lane 40 on the road surface 39 visible to the driver" is the lane located on the opposite side of the driver's seat of vehicle 1. If it is a so-called right-hand drive vehicle where the driver's seat is on the right, then it is the lane located on the left side of vehicle 1. If it is a so-called left-hand drive vehicle where the driver's seat is on the left, then the lane 40 is the lane located on the right side of vehicle 1.

[0031] Although the actual width of the lane 40 on the road surface 39 is approximately 150 mm, when it actually overlaps with the upper edge 20U of the perception guide 20 on the windshield body 13, it appears to be about one-tenth of that, or approximately 15 mm. For this reason, the length of the upper edge 20U of the perception guide 20 in this embodiment is set to, for example, 30 mm.

[0032] The left and right side edges 20S of the perceptual guide 20 are sloped such that their length in the vehicle width direction gradually increases downward from the end of the top edge 20U. The maximum length L2 of each side edge 20S in the vehicle width direction is set to half the length of the top edge 20U (e.g., 15 mm). Also, the height H from the bottom end to the top end of the side edge 20S is set to be the same as the maximum length L2 of the side edge 20S in the vehicle width direction (e.g., 15 mm). Therefore, the angle between the top edge 20U and each of the left and right side edges 20S is set to 135°.

[0033] Figure 4 is a front view showing a portion of a modified sensory guide 20A of this embodiment. In the modified perception guide 20A, the height H from the lower end to the upper end of the side edge 20S is set lower than the maximum length L2 of the side edge 20S in the vehicle width direction. Therefore, the angle α between the upper edge 20U and each of the left and right side edges 20S is set to an angle that satisfies 135° < α < 180°.

[0034] Furthermore, in this embodiment, the sensory guide 20 is installed such that its central position o in the vehicle width direction coincides with the central position OB (Figure 1) of the vehicle 1 in the vehicle width direction. Therefore, the upper edge 20U and each of the left and right side edges 20S of the sensory guide 20 are symmetrical with respect to a vertical line passing through the central position OB (the central position of the windshield body 13 in the vehicle width direction) of the vehicle 1. In other words, the upper edge 20U and each of the left and right side edges 20S extend by the same length in both the left and right directions from the central position OB in the vehicle width direction of the vehicle 1.

[0035] Furthermore, as shown in Figure 2, the perceptual guide 20 is formed such that its upper edge 20U is positioned above the upper edge of the front hood portion 30 of the vehicle 1 as seen by the driver through the windshield body 13. However, in this case, "the upper edge of the front hood portion 30 of the vehicle 1 as seen by the driver" means the upper edge of the front hood portion 30 of the vehicle 1 as seen from the eye point of an adult driver of standard build seated in the driver's seat.

[0036] As described above, the front windshield 10 of this embodiment is set such that when the upper edge 20U of the perception guide 20 and the lane 40 on the road surface 39 visible to the driver coincide while the driver is driving the vehicle, the length L1 of the upper edge 20U is longer than the width w of the lane 40 in the vehicle width direction. This is a shape consideration to prevent the driver from staring at the perception guide 20, and also to flexibly accommodate multiple road width standards so that it can serve as a guide for stable driving. Therefore, the driver can drive the vehicle 1 while maintaining a nearly constant distance from the lane 40 by steering the vehicle so that the upper edge 20U of the perception guide 20 coincides with or is aligned with the lane 40 on the road surface 39. Specifically, while driving the vehicle 1, the driver can adjust the position of their vehicle naturally and without discomfort by steering the vehicle so that the lane 40 is within the range of the upper edge 20U of the perception guide 20, which is longer than the width of the lane 40 from the driver's perspective, or so that it is close to and aligned with the upper edge 20U.

[0037] Here, we will explain the actual appearance of the driver's perception guide 20 and lane 40 while driving a vehicle, and the driver's steering wheel operation at that time, with reference to Figures 3, 5, 6, and 7. Figures 3, 5, 6, and 7 show examples of how the driver perceives the perceptual guide 20 and the lane 40. In these examples, vehicle 1 is a right-hand drive vehicle with the driver's seat on the right side, and the driver is expected to drive while being conscious of maintaining a predetermined distance from the lane 40 to the left of vehicle 1.

[0038] As shown in Figure 3, when the left lane 40 of vehicle 1 is located at the center of the upper edge 20U of the perception guide 20 from the driver's perspective, vehicle 1 maintains an optimal distance from the lane 40. While vehicle 1 is in motion, the left lane 40 of vehicle 1 appears to radiate outwards from a distance towards the upper edge 20U of the perception guide 20 at the center of the front windshield 10 in the vehicle width direction. Also, as shown in Figure 3, the width of the left lane 40 appears to gradually increase as it approaches the upper edge 20U of the perception guide 20. The driver of the vehicle checks the distance between their vehicle and the lane 40 using the left-side mirror 12L, and steers the vehicle so that the lane 40 is within the upper edge 20U of the perceptual guide 20 in their forward view through the front windshield 10.

[0039] As shown in Figure 5, when the lane 40 to the left of vehicle 1 is shifted to near the edge of the upper edge 20U of the perception guide 20 from the driver's perspective, vehicle 1 maintains a distance from lane 40 within an acceptable margin of error. At this time, the driver can recognize that vehicle 1 is slightly shifted in the opposite direction to the shift of lane 40. The driver can then make a gentle steering correction so that lane 40 is within the central area of ​​the upper edge 20U of the perception guide 20.

[0040] As shown in Figure 6, when the left lane 40 of vehicle 1 is positioned so that it overlaps with only one side 20S of the perceptual guide 20 from the driver's perspective, the lateral positional relationship between vehicle 1 and lane 40 is slightly beyond the acceptable margin of error. At this time, the driver can recognize that their vehicle is deviating from the acceptable margin of error by an amount corresponding to the overlapping position of the side 20S and lane 40. The driver can then correct the steering so that lane 40 falls within the upper edge 20U of the perceptual guide 20.

[0041] Furthermore, as shown in Figure 7, when the lane 40 to the left of vehicle 1 is positioned outside one side 20S of the perception guide 20 from the driver's perspective, the lateral positional relationship between vehicle 1 and lane 40 is significantly beyond the acceptable margin of error. At this time, the driver can recognize from the positional relationship between the side 20S and lane 40 as seen through the front windshield 10 that their vehicle is significantly outside the acceptable margin of error. In response, the driver can correct the steering so that lane 40 is within the range of the upper side 20U of the perception guide 20.

[0042] In this embodiment, the front windshield 10 allows the driver to operate the vehicle while recognizing its relative position, such as when the upper edge 20U of the perception guide 20 overlaps with or aligns with the lane markings 40 on the road surface 39. This makes it easier to drive the vehicle while maintaining a nearly constant distance from the lane markings 40, thereby suppressing deviations and swaying within the vehicle's lane and enabling stable vehicle operation.

[0043] Furthermore, in this embodiment, the front windshield 10 is configured such that the length of the upper edge of the perception guide 20 is longer than the width of the lane 40 visible to the driver, thereby preventing the driver from being forced to stare at a single point on the perception guide 20 and aim at a target object with the steering wheel. As a result, the driver can drive the vehicle stably while keeping the relative positions of the perception guide 20 and the lane 40 in their field of vision during normal driving, thus reducing fatigue. Therefore, when the front windshield 10 of this embodiment is adopted, the driver can naturally and without discomfort perceive the positional relationship between their vehicle and the road. Thus, the front windshield 10 of this embodiment can contribute to energy efficiency in the field of vehicle safety technology.

[0044] Furthermore, in this embodiment, the front windshield 10 has side edges 20S extending downward from both ends of the upper edge 20U in the vehicle width direction, and the side edges 20S are inclined so that their length in the vehicle width direction gradually increases downward from each left and right end of the upper edge 20U. Therefore, when the lane 40 on the road surface 39 comes into contact with the inclined portion of the side edges 20S of the perception guide 20 while the vehicle is being driven, it becomes possible to intuitively grasp the amount of deviation from the reference area where the lane 40 and the upper edge 20U of the perception guide 20 overlap, based on the change in height of the overlapping portion of the side edges 20S and the lane 40. Since the change in the amount of deviation that can be perceived while driving is linked to the change in the view seen through the passenger-side side mirror 12L, when the front windshield 10 of this embodiment is adopted, the driver can appropriately judge the direction and amount of steering correction by also looking at the passenger-side side mirror 12L.

[0045] Furthermore, in this embodiment, the front windshield 10 has a maximum length L2 in the vehicle width direction of each side edge 20S, which is positioned on both sides of the upper edge 20U of the perception guide 20, set to half the length L2 of the upper edge. As a result, the maximum length L2 of the side edge 20S in the vehicle width direction becomes half of the maximum adjustment range within the reference area (the area where the lane 40 overlaps with the upper edge 20U), making it easier for the driver to intuitively grasp the amount of deviation from the reference area. Furthermore, in this configuration, the widthwise lengths of the two side edges 20S, which are positioned on both sides of the upper edge 20U in the vehicle width direction, are the same. As a result, the perceptual guide 20 appears visually stable and is less likely to cause discomfort to the driver viewing the perceptual guide 20.

[0046] Furthermore, with this configuration, the length of the side edge 20S that allows the driver to recognize the amount of deviation from the reference area is ensured to be sufficiently long (half the length of the maximum adjustment range within the reference area). As a result, drivers who are looking at the perceptual guide 20 are less likely to feel the need to hastily align the upper edge 20U of the perceptual guide 20 with the lane 40. Therefore, the driver can naturally correct the steering wheel 11 while naturally viewing the forward field of vision.

[0047] Furthermore, in this embodiment, the height H from the lower end to the upper end of the side edge 20S of the perception guide 20 is set to be less than or equal to the maximum length of the side edge 20S in the vehicle width direction. As a result, both the left and right side edges 20S rise gently (not at an acute angle) towards the upper edge 20U, making it less likely for a driver viewing the perception guide 20 to hastily try to align the upper edge 20U of the perception guide 20 with the lane markings. Therefore, when the front windshield 10 of this embodiment is adopted, the driver can naturally correct the steering wheel (steering wheel 11) while naturally viewing the forward view.

[0048] Furthermore, in this embodiment, the front windshield 10 is set so that the central position o of the perception guide 20 in the vehicle width direction coincides with the central position OB of the vehicle in the vehicle width direction. Therefore, by visually observing the upper edge 20U of the perception guide 20, the driver can recognize the central position OB of their own vehicle in the vehicle width direction from the central position o of the upper edge 20U. Therefore, when this configuration is adopted, the driver will be able to operate the steering wheel while being aware of the center position OB in the width direction of their vehicle. Furthermore, in this configuration, the upper edge 20U of the perception guide 20 extends to the left and right by the same length from the center position OB in the vehicle width direction, so that the lateral displacement of the vehicle can be adjusted within the same length range.

[0049] Furthermore, in this embodiment, the front windshield 10 is set so that the upper edge 20U of the perception guide 20 is positioned above the upper edge of the front hood portion 30 of the vehicle 1 as seen by the driver through the windshield body 13. Therefore, when the driver looks forward through the windshield body 13, the intersection of the upper edge 20U and the lane markings 40 on the road surface 39 is not obstructed by the front hood portion 30. Therefore, when this configuration is adopted, the driver can accurately grasp the positional relationship between the lane 40 on the road surface 39 and their own vehicle based on the overlapping position of the upper edge 20U of the perceptual guide 20 and the lane 40 on the road surface 39.

[0050] Furthermore, in this configuration, the front windshield 10 is configured such that the intersection of the upper edge 20U of the perception guide 20 and the lane markings 40 on the road surface 39 is not obscured by the front hood portion 30. Therefore, when the road surface 39 is brightly illuminated by turning on the headlights at night, the driver can clearly recognize the positional relationship between the upper edge 20U and the brightly lit lane markings 40.

[0051] Furthermore, in this embodiment, the perception guide 20 of the front windshield 10 is provided in conjunction with the edging portion 14 of the peripheral edge (lower edge portion 13L) of the windshield body 13. As a result, the perception guide 20 appears to float and become invisible within the windshield body 13 (in the forward field of view). Therefore, by adopting the front windshield 10 with this configuration, the driver will no longer experience the discomfort of foreign matter adhering to a part of the windshield body 13, thereby improving comfort while driving the vehicle.

[0052] Furthermore, if the sensory guide 20 is formed integrally with the border portion 14, or continuously using the same method, as in this embodiment, the sensory guide 20 can be easily provided on the windshield body 13 together with the border portion 14.

[0053] It should be noted that the present invention is not limited to the embodiments described above, and various design modifications are possible without departing from the spirit of the invention. For example, in the above embodiment, the sensory guide 20 is provided so as to be connected to the border portion 14 of the lower edge portion 13L, but the sensory guide 20 may be structured to be spaced apart from the border portion 14.

[0054] Furthermore, in the above embodiment, the central position o of the sensory guide 20 in the vehicle width direction is set to coincide with the central position OB of the vehicle in the vehicle width direction. However, the sensory guide 20 may be positioned so that its central position o in the vehicle width direction is offset from the central position OB in the vehicle width direction. In this case, it is desirable that the top edge 20U and each of the left and right side edges 20S of the perceptual guide 20 be symmetrical with respect to a vertical line passing through the center of the top edge 20U in the width direction.

[0055] Furthermore, in the above embodiment, the side edge 20S of the sensory guide 20 is shaped to be inclined outward in the vehicle width direction, but the side edge 20S may also be shaped to be straight and extend downward without being inclined.

[0056] Furthermore, in the above embodiment, the sensory guide 20 is printed on the windshield body 13 together with the border portion 14, but the sensory guide 20 may also be formed in sheet form and adhered to the surface of the windshield body 13. In addition, the sensory guide 20 may have a three-dimensional shape with thickness in the front-to-back direction. [Explanation of Symbols]
