Abstract:
A control unit of a vehicular headlamp apparatus can selectively perform steering angle control and navigation-cooperative control. The steering angle control operates a drive mechanism based on a steering angle and a speed of a vehicle to control a headlamp's swivel angle. The navigation-cooperative control operates the drive mechanism using a navigation unit to control the swivel angle. When a current position of the vehicle reaches an entry control start point, the control unit starts navigation-cooperative control at the entry into a curved road. The control unit finds a target swivel angle based on a curvature radius and curved road direction information about the curved road. While the vehicle moves from the entry control start point to a curved road start point, the control unit operates the drive mechanism to gradually change the headlamp's swivel angle to the target swivel angle.

Abstract:
In a system for controlling a headlight of a vehicle to be controlled, a distance detector detects a distance between the controlled vehicle and an other vehicle ahead thereof. A determiner determines a first target direction for an optical axis of the headlight in a vertical direction when it is assumed that the optical axis of the headlight passes through a target located at the detected distance with respect to the controlled vehicle. The target has a predetermined height above a predetermined reference point. The predetermined height of the target is unchanged irrespective of change in the detected distance. A first adjuster adjusts the direction of the optical axis of the headlight in the vertical direction so that the direction of the optical axis is matched with the determined first target direction.
Abstract:
A vehicle headlight apparatus receives road data from a navigation system. The apparatus has a first and a second swivel devices for adjusting an optical axis directions of a main light and a sub-light corresponding to one and the other headlights of a right and a left headlights, respectively. The apparatus also has a control unit, which separately controls the first and the second swivel devices, so that a one-eye navigation-cooperated control operation can be carried out which adjusts only the optical axis direction of the main light to be coincident with a road direction calculated based upon the road data.

Abstract:
An apparatus is provided to control an angle of a light axis of light from headlights mounted on a vehicle. In the apparatus, images of a field of view in front of the vehicle are captured, and the captured images are used to detect taillights of a preceding vehicle. A illumination target position is set by using, as a positional reference, a position of the detected taillights in the captured images, and the angle of the light axis so that the light axis is directed to the illumination target position. The command is provided to an angle changing device, where the provided command depends on the angle calculated. The angle changing device changes the direction of the light axis of the light at an angle commanded by the command.
