Description

  The present invention relates to a vehicle with a head-up display, and more particularly, to a vehicle that heads up a scheduled driving line of wheels on a front window and a head-up display device therefor.

  Conventionally, a head-up display has been frequently used in an aircraft cockpit or the like, but in a car, a head-up display on a front window of a driver's seat has not been widespread. Various information such as traveling speed and engine speed can be considered as useful information for a head-up display in an automobile. Particularly useful information for driving is the planned driving line of the wheel (a line indicating where the wheel passes if the vehicle goes straight as it is), but there has been no automobile that performs head-up display.

  An object of the present invention is to make a driver easily and clearly recognize a planned traveling line of wheels, which is important information for driving. For this reason, the motor vehicle which displays the planned driving | running | working line of a wheel with a head-up display, and its apparatus are provided. In particular, the display of the planned traveling line of the wheel on the passenger seat side is extremely important in avoiding wheel removal and collision with obstacles.

  The present invention is an automobile characterized in that a scheduled travel line of wheels is indicated by a head-up display. Further, the apparatus of the present invention has a simple configuration in which a bright line on a rod-like body installed at the upper part of the dashboard is reflected on the front window so that a reflected image can be seen. Here, the dashboard refers to a portion between the instrument panel in front of the driver's seat and the front window and the periphery thereof.

  According to the present invention, the driving line is visually recognized by overlapping with the road and scenery ahead, so that driving is very safe and comfortable. In particular, the display of the planned traveling line of the wheel on the passenger seat side is extremely important in avoiding wheel removal and collision with obstacles. Moreover, since the apparatus of the present invention is ready for implementation and can be realized economically, the apparatus of the present invention is suitable for widespread use of safety-related apparatuses.

  The automobile of the present invention will be described with reference to FIG. FIG. 1 is an explanatory diagram of a vehicle with a head-up display according to the present invention, and is a schematic view of a front view seen from the driver's seat of the vehicle according to the present invention. Reference numeral 1 denotes a front window, in which a roadside line 2 and a centerline 3 of a road displayed in paint are visible. Reference numeral 4 denotes a head-up display of a planned running line of wheels according to the present invention. Reference numeral 5 denotes a head-up display device. This device displays the head-up display on the front window. Reference numeral 6 denotes a dashboard.

  FIG. 1 shows only the head-up display 4 of the planned travel line of the passenger side wheel. In addition, the driver's side wheel's planned driving line may be displayed as a head-up display, but this line is easy for the driver to understand, so the passenger's side wheel's planned driving line far from the driver's seat as shown in this figure. It is more effective to show The planned travel line may vary depending on the driver's body shape, but it is the position of the eyes that directly affects it, so the driver's eye position is measured and processed to determine the travel line and the head-up display is displayed. Become more accurate. Measurement of the eye position can be easily achieved by recent camera-related technology. In this case, the travel line may be fixed thereafter according to the eye position once measured when the driver gets on, or may always follow the eye position by continuous measurement.

  Next, the apparatus of the present invention will be described. The apparatus of the present invention is a rod-like body that can be installed on the upper part of the dashboard, and has a simple configuration in which the bright line on the rod-like body is reflected on the front window so as to see the reflected image. FIG. 2 shows an embodiment of the apparatus according to the present invention. Reference numeral 51 denotes a rod-like body, which is preferably a flexible material that can be easily bent along the curved surface of the dashboard (a material known as a flexible ruler (such as rubber or plastic). A lead bar and a steel strip sealed in a square bar are suitable. Bright lines 52 for displaying lines are provided on the upper surface of the rod-shaped body 51, and the bright lines are preferably composed of one or both of a reflector and a light emitter so that the head-up display image becomes clear. The reflector is preferably a highly reflective tape mixed with glass powder, etc., and the light emitter is preferably a side-scattering plastic fiber or the like. In this case, the light source (bulb or LED) is coupled to the edge near the window. Is desirable.

  The power source device 53 for the light source may be integrally attached to one of the rod-shaped bodies 51. In this case, an on / off switch 54 may be incorporated in the power supply device 53. Reference numeral 55 denotes a locking material, which is provided on one or both of the lower surface of the rod-shaped body and the lower surface of the power supply device. The locking material 55 functions to prevent the device from shifting due to the acceleration of the vehicle when the device is placed on the dashboard. Adhesive tape having a high coefficient of friction is suitable, and even if an adsorbent material or a suction cup is combined. good. The locking material may be a short pin with a sharp tip. In addition, it is desirable that the entire apparatus other than the bright line has a glossy black color that is difficult to reflect. In addition, when the power source of the light source of the apparatus is a battery mounted on an automobile, on / off switching of the automobile light may be linked with on / off switching of the light source of the apparatus.

  The length of the bright line or rod-like body of the present invention is close to a point when it is short, but has the effect of the present invention. However, it is much easier to see if the length is several centimeters or more and the head-up display is also in a corresponding line. In addition, it is conceivable to put the substance at the position of the head-up display 4 in FIG. 1, but this is not preferable because it hinders the real field of view. The head-up display 4 has a difference in focus from the real field of view and a parallax between the left and right eyes different from the real field of view, but this has no problem in recognizing the running line. It gives me a feeling and gives me the advantage of not obstructing the real field of view.

  In the prototype, a bright light line with a side-scattering plastic light guide (diameter: about 5 mm) combined with a red LED, with a yellow highly reflective tape affixed intermittently, was used in the daytime. However, the red color at night was displayed as a head-up display in the form of dotted lines.

  Next, the procedure for realizing the automobile of the present invention using the head-up display device of the present invention will be exemplified. First, the passenger side wheel of the automobile is stopped along a line indicating the road side painted on the road, for example. This can be done easily by looking at the rearview mirror. If the front window is viewed in this state, the roadside line appears to extend diagonally forward from the middle part of the window (from the middle part of the bonnet if the bonnet is projected). If the apparatus of the present invention is locked on the dashboard so that the head-up display according to the present invention overlaps this line, the installation is completed, and the automobile of the present invention is realized. After that, in normal driving, the planned driving line is always displayed on the front window as shown in FIG. In the above description, the description has been made centering on the planned traveling line display of the passenger side wheel, which is more effective, but it goes without saying that the planned traveling line of the driver side wheel may also be displayed. According to the present invention, the scheduled travel line with good visibility is displayed without hindering the real field of view, so the present invention is indispensable for comfortable and safe driving.

It is explanatory drawing of the motor vehicle with a head-up display of this invention, and is a schematic diagram of the front view seen from the driver's seat of the motor vehicle of this invention. It is a perspective view which shows one Example of the head-up display apparatus of this invention.
