<p><P>PROBLEM TO BE SOLVED: To provide a light distribution controller capable of suitably adjusting an irradiation range of a headlight, without generating glare to a driver of a preceding vehicle and an oncoming vehicle. <P>SOLUTION: The light distribution controller comprises a vehicular detecting means for detecting the preceding vehicle and the oncoming vehicle, and a light distribution amount calculating means for calculating the light distribution amount of the headlight independently in right and left sides on the basis of information from the vehicular detecting means, so that the strength of a high beam and a low beam of the right and left headlights can be controlled independently in the right and left sides. Headlight control can be carried out at low cost, because an optical axis changing means is not used. In addition to the structure, a road information detecting means for detecting road information in front of an own vehicle, and a headlight optical axis changing means capable of changing the optical axis of the headlight are provided, so that in addition to strength control of the high beam and the low beam of the headlight, the optical axis of the headlight can be controlled in a lateral and vertical directions. Consequently, suitable light distribution control can be carried out. <P>COPYRIGHT: (C)2004,JPO</p> |
