Embodiments of the present invention will be described below with reference to the drawings.
A guide display 1 as an information display device of the present invention includes guides 1a and 1b formed on a dashboard 100 as shown in FIG.

  The standard 1a is formed in a portion on the passenger seat side of the dashboard 100 so as to extend toward the left front and its width dimension increases in the distal direction. Then, a virtual image of the standard 1a is projected on the windshield, and this virtual image is presented as a vehicle width line (information used as a standard when the passenger seat side is shifted).

  The standard 1b is formed on the driver seat side portion of the dashboard 100 so as to extend toward the right front, and its width dimension increases toward the front end direction. Then, a virtual image of the standard 1b is projected on the windshield, and this virtual image is presented as a vehicle width line (information serving as a standard when the driver seat side is shifted).

In addition, the standard 1a, 1b corresponds to a display part, and the dashboard 100 corresponds to a holding part.
As described above, according to the guide display 1 of the present embodiment, the guides 1a and 1b as described above are formed at predetermined positions on the dashboard 100 as illustrated in FIG. 1, FIG. 2 (1), and FIG. Therefore, it can be easily installed on the vehicle and does not hinder the visual recognition of the outside through the windshield. In addition, when the guides 1a and 1b are arranged at predetermined positions on the dashboard 100, the virtual images of the guides 1a and 1b are projected on the windshield, so the virtual images of the guides 1a and 1b projected on the windshield and the parked vehicle Obstacles such as oncoming vehicles can be directly compared and the positional relationship between the vehicle and the obstacles can be easily understood. In addition, since the virtual images of the guides 1a and 1b projected on the windshield can be directly compared with the white line, driving the vehicle to maintain the appearance of the virtual image and the white line or obstacles can be maintained. This makes it easier to perform the steering operation (see FIG. 8). That is, the guides 1a and 1b can suggest an appropriate steering operation by comparing the virtual image with the road installation.

As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, It is possible to implement in the following various aspects.
For example, as illustrated in FIG. 2B, an area surrounded by the guides 1a and 1b on the dashboard 100 is formed as a guide 1c, and a virtual image of the guide 1c is presented as a region indicating the inside of the vehicle width. Alternatively, areas outside the standards 1a and 1b on the dashboard 100 may be formed as the standards 1d and 1e, and the virtual images of the standards 1d and 1e may be presented as areas indicating the outside of the vehicle width. It may be.

  Further, as illustrated in FIG. 2 (3), the virtual images of the guides 1d and 1e are formed by forming the guides 1a and 1b as a set of left and right line segments and extending some of the line segments outward. You may make it possible to confirm in advance the passing with the oncoming vehicle. In addition, what is necessary is just to confirm with visual observation or a mirror when an oncoming vehicle approaches.

  Further, as illustrated in FIG. 2 (4), the standard 1 f may be installed on the dashboard 100 separately from the standards 1 a and 1 b. And if a steering is operated so that the target object (wall etc.) to adjust width | variety may be match | combined with the standard 1f, a vehicle can be made into a straight (parallel) state with respect to the said target object.

  The guides 1a and 1b may be formed by writing directly on the dashboard 100 such as using fluorescent paint (see FIG. 3 (1)), or the sheet 2 on which the guides 1a and 1b are printed, A plate or the like may be placed on the dashboard 100 (see FIG. 3B). The guides 1a and 1b may be formed by directly writing on the windshield, or the guides 1a and 1b may be irradiated on the windshield with a laser or the like (see FIG. 3 (3)). In addition, LEDs (corresponding to light emitting units) may be installed on the dashboard 100 as guides 1a and 1b, and the virtual images may be projected on the windshield by turning on the LEDs (see FIG. 3 (4)). The LEDs may be installed on the dashboard 100 by being housed in a case (corresponding to the holding portion) in which movable guides 1a and 1b are formed on the surface by a slide operation (corresponding to the adjusting portion) or the like. Moreover, you may make it make a driver image the extension top (extension line) on the dashboard 100 or a bonnet using the front-end | tip of the standard 1a, 1b (refer FIG. 3 (5)). Further, when the surroundings are dark, such as before dawn or after sunset, a vehicle width line may be formed on the road using the light emitted from the headlight (see FIG. 3 (6)). Moreover, you may make it form a vehicle width line using the wiper 3 (refer FIG. 3 (7)).

  In addition, for the measures 1a and 1b, it is preferable to reduce the line segment variation due to the parallax between the eyes and allow the driver to make a margin. From this point of view, the measures 1a and 1b may be formed as a collection of points (see FIG. 4 (1)) or a collection of line segments (horizontal lines) (FIG. 4 (2)). reference). Moreover, you may form the standard 1c which is the area | region enclosed by the standard 1a, 1b and the standard 1a, 1b as an aggregate | assembly of a horizontal line (refer FIG. 4 (3)). The guides 1a and 1b may be formed as thick lines (see FIG. 4 (4)) or may be formed as transmission lines (see FIG. 4 (5)).

  Band-shaped guides 1g and 1h may be formed outside the guides 1a and 1b, respectively (see FIG. 5A). The virtual images of the guides 1g and 1h function as a guide for dealing with passing and width-shifting with a margin, and the guides 1a and 1b function as a severe line. In this case, the guides 1a and 1b are highlighted on the outside by comparison with the strip-like guides 1g and 1h, and the guides 1a and 1b are also highlighted by making them bold lines or prominent colors. It becomes. Alternatively, each of the indications 1a and 1b may be configured as a plurality of rows of LEDs, and only a specific row of LEDs may be lit by a driver's switch operation (see FIG. 5B). For example, the virtual image of the outer LED functions as a guideline for dealing with passing and width-shifting, and the inner LED virtual image functions as a guideline for dealing with a state where there is not much room for passing and width-shifting. And so on.

  In addition, it is desirable that the shape of the reference display is a shape composed of a straight line portion and a curved portion so that it can be easily understood which portion of the target should be matched with the target (see FIG. 10). By doing so, the driver intuitively tries to match the straight portion and the object, so that the usage of the guide becomes clear. For example, in the guide display 1, when the driving guide function is turned on, the guide 1i is turned on and the virtual image is projected onto the windshield. Here, the standard 1i is composed of a linear component and a curved component so that it can be intuitively understood where the object should be placed in the virtual image. Thus, even when it is unclear how far the width can be adjusted, the vehicle is moved forward while performing the steering operation so as to match the virtual image of the reference 1i and the object to be adjusted, thereby bringing the vehicle closer to the object (width) And anxiety that can be felt at the time of width adjustment. In addition, with regard to the fear that the car will not move as expected by the driver (cannot be operated according to the image), the vehicle body can be straightened against the obstacle. Moreover, the standard display 1 can be easily installed.

  Pay attention to the fact that the colors are easy to see when the surroundings are bright, such as during the daytime, and when the surroundings are dark, such as before dawn or after sunset, and select the approximate 1a and 1b colors according to the ambient brightness. May be. For example, when the surroundings are bright, the LEDs of the indicators 1a and 1b are lit in yellow green. Further, when the possibility of the vehicle coming into contact with an obstacle increases due to sensing, the LEDs of the indicators 1a and 1b may be changed from green to amber. Further, it may be determined whether or not it is possible to pass the oncoming vehicle by sensing, and the colors of the standards 1a and 1b may be selected according to the determination result. Moreover, you may make it adjust the illumination intensity of LED according to a surrounding condition. In addition, a guideline may be separately provided on the dashboard 100 so that the virtual image is presented as information for assisting the grasp of the vehicle sense regarding the lower part (tire, bottom) of the vehicle. Moreover, about the standard 1a, 1b, it is good to form so that the virtual image may extend to the horizon.

  Moreover, about a standard, it is good to be comprised in the form which suggests that the virtual image will be projected on a windshield and it will become a standard at the time of width adjustment, if it arrange | positions in the predetermined position of the dashboard 100. FIG. For example, in the standard 1i illustrated in FIG. 10, the display unit is configured in a semicircular shape, and can further be widened while the lane overlaps the virtual image of the curved part of the display unit. When the lane overlaps the virtual image, it is suggested that it is preferable to arrange the lane on the dashboard 100 so that further width adjustment is impossible.

  In addition to the dashboard 100, the guide is also installed on pillars, and the virtual image is projected on the window glass such as rear glass and side glass in addition to the windshield to help grasp the vehicle sense of the front, rear, left and right of the vehicle. You may make it show as information to do.

In addition, the following method is conceivable as a contrivance for preventing a difference in the appearance of the reference (the positional relationship between the reference virtual image and the obstacle) depending on individual differences and postures.
(A) A lens 4 (corresponding to a suggestion) with a narrow viewing angle is placed on the dashboard 100, and the approximate virtual image is viewed from a position where the double circle mark in the lens can be seen without being scraped. (See FIG. 6A).

  (B) When the lenticular lens (corresponding to the suggestion part) is viewed from the position where the design of the lenticular lens can be visually recognized, the positional relationship between the vehicle width line and the obstacle is appropriate on the dashboard 100. Install and look at the virtual image from the position where you can see the design of the lenticular lens.

  (C) The length of the virtual images of the guides 1a and 1b is obtained by installing the sheet 5 on which the guides 1a and 1b are formed on the dashboard 100 and folding a part of the sheet 5 by the fold line formed between the guides 1a and 1b. The sheath angle is adjusted (see FIG. 6B).

  Further, in the above-described reference display device 1, in order to use a LED or determine passing by sensing, the following system configuration may be used. That is, as shown in FIG. 7, the guide display device 1 may have a system configuration including a guide presentation (display) function and a periphery monitoring function. Among these, the guideline presentation (display) function includes the guideline correct alignment presentation function, posture adjustment function, guideline presentation position adjustment function, guideline presentation ON / OFF function, guideline presentation (display) function (LED), and guide contrast adjustment function. The peripheral monitoring function includes a monitoring ON / OFF function, a distance sensing function with an obstacle, a collision detection function (corresponding to a prediction unit), an information presentation function to a user (corresponding to a notification unit), and a monitoring system state It consists of a monitoring function.

Further, as countermeasures when it is determined that the passing is impossible by sensing, a countermeasure manually performed by the driver and a countermeasure automatically performed by the system can be considered (see FIG. 9).
One of the manual actions taken by the driver is to prompt the driver to display his / her intention in order to tell the other side that he / she will not pass, and inform the other person to stop and wait here In order to urge the driver to turn on the hazard or to turn off the light, to encourage the driver to pass or to ask the other person to deal with or to horn the driver And so on.

  In addition, as a countermeasure that the system performs automatically, the intention is automatically displayed to tell the other party that you are not passing by, and the hazard is automatically notified to inform the other party that you are waiting and stopping at this place. For example, you can turn it on or turn it off automatically, or you can automatically pass or ask the other party to deal with it.

Moreover, about the standard indicator 1, when the input from a passenger is received and the passenger's judgment that display is not required is received, you may make it not display the said.
In addition, for the guide display 1, when it is predicted that the vehicle can pass without touching the obstacle, information intended to ease attention such as information that is comfortable for the passenger is provided, and the vehicle becomes an obstacle. When it is predicted that it is not possible to pass without touching, information intended to alert or warn may be provided.
