Description

Presetting device for head-up display {APPARATUS FOR PRESETTING A HEAD-UP-DISPLAY}

The present invention is a display device for a vehicle that displays various types of information such as the speed, fuel amount, temperature, and warning direction of the vehicle to the driver. The present invention relates to a pre-setting device for a head-up display for correcting and setting an image distorted by assembly tolerances, mirror curvatures, etc. into a good image before mounting a head-up display providing other information to a vehicle.

If we look at human living space, we can distinguish three kinds of living space: house, workplace, and moving space. In particular, the vehicle occupies most of the moving space.

Such a vehicle is generally provided with a cluster on which various information related to the running state of the vehicle is displayed. The instrument panel is composed of a speedometer, a fuel meter, a thermometer, and various warning lamps. The driving state of the vehicle is grasped and the safe driving is performed. Therefore, the instrument panel is installed in front of the dashboard in which the driver can easily gaze while driving.

However, the driver operates the driver through the front glass of the vehicle while checking the forward visibility, and moves the gaze to the dashboard at any time to check the instrument panel. At this time, the movement of the gaze is large and the focal distance of the eye As the above situation continues, fatigue easily occurs. In particular, when the driver gazes on the instrument panel while driving, the front vision can not be confirmed, and thus, there is a risk of accident.

A head-up display (HUD) is widely known as a medium for effectively conveying vehicle driving information and surrounding information to a driver in order to secure driving safety during driving of the driver.

The head-up display of a vehicle is a display device that provides vehicle driving information or other information in front of the driver during the driving of the vehicle, that is, within a range that does not deviate from the driver's main visual line. In the early days, It is also installed in vehicles.

There is a danger that the time to set the field of view on the dashboard during the normal speed of about 100 km / h driving, and the time to fix the field of view forward is about 2 seconds, about 55 m. One of the ways to reduce this risk is the background of the head-up display of the vehicle. The head-up display of the vehicle displays information on the instrument panel (speed, mileage, RPM, navigation information, etc.) So that the driver can easily grasp the traveling information even while driving. This allows the driver to keep safe driving by recognizing important driving information without taking his eyes off the road ahead.

1 is a schematic view showing a state in which a dashboard and a head-up display are installed in a general vehicle. The ECU 10 receives information from various sensors installed in the vehicle 1, receives signals from the ECU 10, An instrument panel 20 for computing information relating to the running state of the vehicle 1 and displaying information relating to the running state of the vehicle 1 and a control unit 20 for receiving signals from the ECU or the instrument panel 20, Up display 30 for displaying information related to the running state of the vehicle 1 on the windshield 2 of the vehicle 1 as an image. The driving state of the vehicle 1 is detected by the instrument panel 20 and the head-up display 30 in the cluster through the instrument panel 20 or on the front glass 2 through the center fascia or head- Image.

Figure 2 is a perspective view showing a head-up display according to the prior art, Figure 3 is an exploded perspective view of the embodiment of Figure 2, Figure 4 is a perspective view showing the movement path of the image by removing the window cover in the embodiment of Figure 2 .

The head-up display 30 according to the related art includes a case 31, which is buried in the upper portion of the dashboard 3 of the vehicle 1 and opens upward, as shown in Figs. 2 to 4 with reference to Fig. 1, A control board 32 fixed to the lower surface of the case 31; a black cover 33 fixedly installed inside the case 31 so as to cover the control board 32; (31) for receiving information related to the traveling state of the vehicle (1) from the control board (32) and outputting the image as an image and projecting the information in the right direction of the case (31) (35) installed on the upper right side of the black cover (33) and reflecting the image projected from the video output section (34) to the front of the case, And an image reflected from the plane mirror 35 is reflected by the case 31, A window 37a is provided so that an image is displayed on the front glass 2 of the vehicle 1 by transmitting an image reflected from the circumferential surface 36 and the case 31 And a window cover 37 for closing the upper portion of the window cover 37. [ A rotation motor 38 for rotating the concave mirror 36 according to a control signal of the control board 32 is provided to adjust the height of an image displayed on the windshield 2 of the vehicle 1. [

The head-up display 30 according to the related art, which is configured as described above, rotates the concave mirror 36 by driving the rotary motor 38 according to a sitting key or a posture of a driver after the vehicle is mounted on the windshield 2. You can only adjust the height of the image displayed on the screen. Of course, if only the image projected from the image output unit 34 is viewed, a company that produces and delivers the image output unit 34 naturally corrects the distortion degree of the image projected from the image output unit 34 to project a good image. Will be checked and delivered as soon as possible. However, companies that produce and sell the head-up display 30 are designed and assembled to combine and operate the respective components constituting the head-up display 30.

At this time, since each component constituting the head-up display 30 may not be completely identical in reality, as well as design errors, processing tolerances and assembly errors, as well as the mirror curvature of the flat mirror 35 or the concave mirror 36, etc. Due to the slight difference, when the image projected from the image output unit 34 is displayed as an image on the windshield 2 of the vehicle 1, the image displayed from each head-up display 30 is all distorted differently. Is displayed. For example, the distortion of an image or an image includes a left and right, a vertical zoom, a rotation, a rotation, a shear, a curve, a front and rear slope, a smile, and the like, as widely known.

Therefore, after assembling each of the components constituting the head-up display 30, mounting it in a vehicle, boarding a driver's seat, and then correcting the distorted image to a good image while viewing the image displayed on the windshield 2. Most preferred. However, it is practically impossible to disregard the fixed production line of the vehicle and not only to install the head-up display 30 in the vehicle, but also to correct the image of the head-up display 30 installed in each vehicle.

Then, looking at how the image correction of the head-up display 30 is currently performed, as shown in FIG. 5, it corresponds to the windshield 2 of the vehicle 1 to which the head-up display 30 is to be mounted. The inspection glass 5 is installed, and the fixing jig 6 is installed to correspond to the position at which the head-up display 30 is mounted on the vehicle 1. After fixing the head-up display 30 to the fixing jig 6, the operator operates the control panel 7 connected to the head-up display 30 while visually viewing the image displayed on the inspection glass 5. Will be corrected.

As described above, since the presetting of the conventional head-up display 30 is performed manually by the naked eye of the operator, first, a difference in the standard of a good image occurs according to the first operator, and second, even if the same worker The correction is inevitably different, and since the correction process of the third image is performed by the naked eye, there is a problem that the operator easily fatigues and takes a long time.

The object of the present invention devised to solve the above problems is to improve the speed and convenience of the image correction operation of the head-up display with a simple configuration, and to determine the good or bad through comparison with the standard pattern and the test pattern An object of the present invention is to provide a pre-setting device for a head-up display that can clarify and ensure continuity of quality.

Reflects the image projected from) in the other direction of the interior of the dark room (200). Since the reflector 400 should reflect the image projected from the head-up display (HUD) mounted on the fixing jig 300, the reflecting mirror 400 is positioned on one side of the dark room 200 as the fixing jig 300, and more specifically, fixing is performed. The reflector 400 is inclined above the jig 300 to reflect the image projected from the head-up display HUD mounted on the fixing jig 300 in the other direction of the interior of the dark room 200.

6 to 9 is installed on the upper portion of the frame 100 to be located on the other side inside the dark room 200, as shown in Figure 6 to 9 to take an image reflected from the reflector 400. That is, the image projected from the head-up display (HUD) mounted on the fixing jig 300 is reflected in the other direction of the interior of the dark room 200 through the reflector 400, and is located in the other direction of the interior of the dark room 200. The camera 500 photographs an image reflected from the reflector 400.

The position of the fixing jig 300 described above corresponds to the dashboard 3 of the vehicle 1 on which the head-up display HUD is to be mounted, and the position and shape of the reflector 400 are to be mounted on the vehicle 1. Corresponding to the windshield 2, the position of the camera 500 corresponds to the field of view of the driver sitting in the driver's seat of the vehicle (1) to be mounted. Therefore, the image projected from the head-up display (HUD) mounted on the fixing jig 300 and reflected on the reflector 400 to be photographed by the camera 500 corresponds to the driver's seat of the vehicle 1 to be mounted correspondingly thereto. It is designed to be identical to the image seen in the driver's field of view.

If so, a display panel 610 for displaying an image captured by the camera 500 to be viewed by an operator should be provided, and the control panel 620 may correct the image displayed on the display panel 610. The controller 600 is provided to display an image on the display panel 610 and to control the head-up display HUD according to the manipulation of the control panel 620.

That is, the controller 600 receives the image photographed from the camera 500 and displays it on the display panel 610 as shown in FIGS. 6 to 9, and displays the display panel according to an operation of the control panel 620. The head-up display HUD is controlled to correct the distorted image displayed at 610 to a good image. The control unit 600 is substantially a central processing unit such as a computer main body, and may be installed anywhere in the frame 100. However, it is electrically connected to the head-up display (HUD), the camera 500, the display panel 610, and the control panel 620 to transmit and receive signals with each other to operate in conjunction with each other.

As described above, it is obvious from the viewpoint of the worker that it is confirmed by the image captured by the camera 500 and displayed on the display panel 610 rather than visually determined by the operator. The speed and convenience of work can be improved. In addition, if the image displayed on the display panel 610 can be confirmed more quickly and conveniently from the operator's point of view, and the comparative analysis with the good image is more clear, the speed and convenience of the work can be increased. To this end, as illustrated in FIG. 10, the image projected from the head-up display HUD is a test pattern TP, and the display panel 610 matches a preset good pattern GP and the good pattern GP. The display is divided into the standard pattern SP, and the test pattern TP is displayed based on the standard pattern SP. Accordingly, the operator can easily manipulate the control panel 620 so that the test pattern TP projected from the head-up display HUD matches the standard pattern SP according to the good pattern GP. In this case, the controller 600 may change the display panel 610 according to the operation of the control panel 620 to determine whether the test pattern TP displayed on the display panel 610 matches the standard pattern SP. The determination is made to be displayed on the control panel 620.

On the other hand, the test pattern (TP), good pattern (GP) and the standard pattern (SP) each has the same shape, so that the operator can easily and conveniently operate and check the column as shown in Figure 10 in the rectangular border The image may have a cross shape. This shape of the image, the operator is easy to match the test pattern (TP) to the standard pattern (SP), first to complete the up and down and left and right movement based on the intersection of the crisscross, and proceeds to rotate around the crisscross This is because enlargement, left and right inclinations, left and right curves, front and rear inclinations, and smiles can be sequentially performed based on the rectangular edges.

The display panel 610 is a general flat panel display, whereas the control panel 620 is an input device because a control operation must be possible. That is, the control panel 620 may simply be a push button input device, may be a touch screen in which an input device and a display device are combined as shown in FIG. 11, or may be in a form in which an input device is connected to the display device. . In any manner, the control unit 600 may display the changed image on the display panel 610 while controlling the head-up display HUD according to the operation of the control panel 620. At this time, the display panel 610 and the control panel 620 is preferably installed in a position that can be easily manipulated by the operator, as shown in Figures 6 to 9 the display panel 610 and the control panel Each of the 620 may be fixedly installed above one side of the dark chamber 200 so as to face the opened one side direction of the dark chamber 200.

Meanwhile, if the fixing jig 300 and the reflecting mirror 400 are simply fixed to the upper part of the frame 100 with reference to FIG. 6, the operator views the head up display (HUD) on the fixing jig 300 when looking at the moving path of the image. ) Will not be easy to mount and dismount or replace. Therefore, the fixing plate 300 may further include a rotating plate 700 in order to ensure easy replacement, such as mounting and dismounting of the head-up display (HUD). That is, the rotating plate 700 is rotatably installed on the upper portion of the frame 100 so as to be located on one side of the dark chamber 200, and rotates 180 degrees forward and backward from one side direction to the other side of the dark chamber 200. In this case, the fixing jig 300 and the reflector 400 are fixed to the upper portion of the rotating plate 700 and rotate together with the rotating plate 700. As shown in FIGS. 7 and 8, when the head-up display (HUD) is mounted on the fixing jig 300 or when the head-up display (HUD) is replaced or replaced, the rotating plate 700 is rotated to one side to be easily installed and released, and the fixing jig is fixed. After mounting the head-up display (HUD) to the 300, as shown in Figure 9 will be rotated 180 degrees in the other direction to start the pre-setting.

As described above, the pre-setting device for head-up display according to the present invention improves the speed and convenience of image correction operation of the head-up display (HUD) with a simple configuration, and the head through the reflector 400 and the camera 500. The image projected from the up display HUD is displayed on the display panel 610 and compared with the standard pattern SP and the test pattern TP. Determination of defects can be clarified to ensure continuity of quality.
