    摘要: A method for validating an illumination-range test value of a light cone of at least one headlight of a vehicle. The method includes reading in a reflection intensity of a point on at least one road marking illuminated by the light cone; generating a reflection intensity model for the road marking, based on the obtained reflection intensity and a particular distance of the point from the vehicle, the reflection intensity model being designed to assign different reflection intensities to different positions on the road marking in front of the vehicle; determining an illumination-range plausibility value, at which, according to the reflection intensity model, a reflection intensity is reached, which corresponds to a reflection-intensity threshold value; and comparing the illumination-range plausibility value to the illumination-range test value, to validate the illumination-range test value, if the illumination-range plausibility value is inside a tolerance range around the illumination-range test value.

    摘要: An optical axis of a headlight of a vehicle is adjusted by picturing an illuminating pattern of the headlight to appear on a screen which is disposed in front of the vehicle. A position of a center of gravity of a region above a predetermined illuminance in the illuminating pattern is obtained. A position of a stepped region in which a stepped portion of a light/dark border line of the illuminating pattern is present is obtained. A position of a point of inflection, in the stepped region, of an iso-illuminance curve having a predetermined rate of illuminance relative to an illuminance in the center of gravity is measured. The optical axis is adjusted based on this point of inflection.

    摘要: An illuminating pattern to appear on a first screen which is disposed in front of a headlight is pictured by a camera. A light-shielding panel is disposed on substantially the same plane as the first screen. A pin hole is formed in the light-shielding panel. The light to penetrate through the pin hole is illuminated via a mirror on a second screen which is on a surface behind the light-shielding panel. On the second screen there is formed an imaginary light source image which is to be formed on a reflecting light of the headlight. This image is pictured by the camera together with an illuminating pattern on the first screen. From the position of the imaginary light source image the actual position of the headlight is located, and the position of an acceptable range, within which a reference measuring point inside the illuminating pattern falls, is corrected depending on the position of the headlight so that the reference measuring point may fall within the acceptable range. Since the shape of the imaginary light source image varies with the orientation of the optical axis, the optical axis may also be adjusted such that the imaginary light source image becomes a normal shape.

    摘要: A headlamp testing method of the invention involves the steps of applying the low beam of the headlamp onto a screen, determining the position of the geometrical center of a closed area of illuminance higher than a predetermined level, determining the position of a cut off line cross point from the position of the geometrical center and a predetermined amount of offset, and determining a presumption line cut off line from the cut off line cross point. The presumption line thus determined is displayed together with a mark which indicates the within which the cross point should fall, and the headlamp beam is judged as being acceptable when the cross point is located within this range.

    摘要: A method of examining the state of alignment of headlamp beam axis has the following steps: taking up by a TV camera the image of the light distribution pattern of a headlamp beam on a screen; specifying a closed curved area of illumination intensities higher than a predetermined level in the taken-up image of the light distribution pattern; determining the position of the geometrical center of the specified closed curved area and displaying the position of the geometrical center on a monitor TV; measuring the area of the specified closed curved area; comparing the measured actual area of the closed curved area with a command area; adjusting the quantity of light received by the TV camera in accordance with the result of the comparison until the measured actual area of the closed curved area becomes equal to the command area; and displaying, on a monitor TV, a pattern representing the allowable range and a mark representing the position of the beam axis. When the marks falls within the allowable range, it is judged that the state of alignment of the beam axis is acceptable.
