  • Patent number: 10220764
    Abstract: A vehicular head-lighting system includes: an identification unit that from a plurality of zones defined in front of a driver's vehicle identifies a zone in which a frontward vehicle is located; and a selection unit that in accordance with the zone identified by the identification unit selects from the plurality of light distribution patterns a light distribution pattern that is to be formed. The selection unit selects the low beam light distribution pattern when the identification unit identifies the frontward vehicle as being located in the first zone, selects the adaptive high beam light distribution pattern when the identification unit identifies the frontward vehicle as being located in the second zone, and maintains the currently selected light distribution pattern when the identification unit identifies the frontward vehicle as being located in the transitional zone.

  • Patent number: 9956901
    Abstract: A curvature estimation unit estimates the curvature of the road on which a vehicle is driving. A swivel angle setting unit is configured to perform a first mode in which a swivel angle of a lamp unit is set such that a light distribution pattern follows the travelling direction of the vehicle based on the curvature estimated by the curvature estimation unit, and perform a second mode in which a swivel angle of the lamp unit is set such that a shielded area created in a light distribution pattern follows the position of the vehicle detected by a vehicle position detector. A pattern determination unit determines a light distribution pattern such that the position of the vehicle detected by the vehicle position detector remains in the shielded area. A swivel angle setting unit performs the first mode when it is determined that the road is a curved road based on the curvature estimated by the curvature estimation unit, and performs the second mode when it is determined that the road is a straight road.
