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: Lamp units for radiating a beam ahead of a vehicle in a light distribution pattern are housed in a lamp body. Illumination of the auxiliary lamp units is controlled based on driving conditions. Illumination control means extinguish light through dimming by gradually decreasing voltage applied to the light sources. When the applied voltage has dropped to a threshold value, the applied voltage is controlled to zero immediately. Compared to when the lamps remaining in an illuminated state are suddenly extinguished, a change in quantity of light is mild, and no uncertainty arises. Below a threshold value where the applied voltage gradually drops to the threshold value and a change may arise in the filament crystalline structure due to annealing at a transition temperature, the applied voltage approaches zero. Hence, the filament does not pass from the transition temperature while being rapidly cooled, thus avoiding filament crystalline structure change.

Abstract: Front viewability during turning may be enhanced by a headlamp device for a vehicle arranged to perform swivel control The headlamp device is arranged so that when a vehicle 2 is turning around a right curve with low beam, the vehicle velocity V and the estimated horizontal G value are used to calculate the curve turning radius R, which is then used together with the vehicle velocity R to calculate the driver viewing point angle θ to which the leftward deviation β of the highest light intensity position in the light distribution pattern PL for low beam is added to calculate the target swivel angle α on the basis of which the lighting fixture unit of the headlamp 10R is swung over the target swivel angle α so that light beam is emitted toward a region surrounding the driver viewing point EP on the road ahead of the vehicle in the forward direction. In this arrangement, the driver viewing point angle θ can be calculated using only from the vehicle velocity data as a parameter without using steering angle data, making it possible to simplify the operation for swivel control and to eliminate the need to use a steering angle sensor.

Abstract: A steering wheel is determined to be under a counter steering state when the following two conditions are both satisfied: (I) a steering angle measured with a steering angle sensor is equal to or greater than a predetermined angle; and (II) a steering direction does not coincide with a turning direction of the vehicle. The vehicle is determined to be under a slipping state when the following two conditions are both satisfied: (I) the steering angle is equal to or greater than the predetermined angle; (II) an absolute value of a change per unit time of a difference between a left wheel speed and a right wheel speed is equal to or greater than a predetermined value. Under both the counter steering state and the slipping state, adjustment of the optical axes of the swivel lights is stopped or modified.
