The present invention relates to a vehicle headlight irradiation angle automatic adjustment device. More particularly, during nighttime vehicle driving, a conventional headlight of a vehicle is divided into an upper light and a downward adjustment light by upward and downward angle adjustments of the headlight, and thus there has been a problem that when the headlight is adjusted downwards, a long distance cannot be seen, and when the upper light is used, if the distance to a preceding vehicle is short, the vision of the preceding vehicle may be disturbed. The present invention was devised to resolve such a problem. The present invention enables a headlight to be automatically adjusted downwards when the distance to a preceding vehicle is short, and enables the upper and lower angles of the headlight to be automatically adjusted such that the light of the headlight reaches as far as possible into the distance, while not disturbing the vision of the preceding vehicle when there is no preceding vehicle, or when the preceding vehicle is located a long distance away. In order to have such functions, the vehicle headlight irradiation angle automatic adjustment device of the present invention forms a laser distance measurer on the front surface or a headlight of a vehicle. In addition, the vehicle headlight irradiation angle automatic adjustment device of the present invention comprises: a switch for outputting an electric signal in connection with the operation of a switch for turning on a headlight of a vehicle; the laser distance measurer for detecting the distance to the preceding vehicle and outputting the distance as an electric signal; a control means configured to operate according to the signal outputted from the switch, to receive the signal from the laser distance measurer, which is a means for detecting the distance to a preceding vehicle, and the means for detecting the distance to the preceding vehicle, to calculate a slope angle which is a degree at which the headlight is adjusted upwards or downwards by the received signal, and to output a signal for adjusting the angle of the headlight; and a headlight angle adjusting means which operates according to the signal outputted from the control means and adjusts the irradiation angle of the headlight of the vehicle.
