ABSTRACT:
A light distribution control device includes a projection type headlamp for a motor vehicle in which a clear cut line in a light distribution pattern is varied by rotating a shade for forming a clear cut line about a horizontal support shaft. A vehicle-to-vehicle distance measuring sensor for measures a distance between a vehicle carrying the light distribution control device and another vehicle running in front of the former, and a shade rotation control unit controls the rotational position of the shade. The angular position of the shade at which the amount of glare at an eye point specified by a vehicle-to-vehicle distance and a rotation angle of the steering wheel is smaller than a tolerable quantity of glare is stored in the form of table data in the control unit. The control unit sets the rotational angle of the shade on the basis of distance information measured by the vehicle-to-vehicle distance measuring sensor, and the steering angle of the steering wheel.
