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.
An automotive headlamp apparatus comprising:
A controller for an automotive headlamp apparatus, comprising a swivel angle setting unit configured to receive a position of a forward vehicle from a vehicle position detector and to set a swivel angle of lamp units according to a first mode in which a light distribution pattern created by the lamp units follows the travelling direction of a vehicle containing the headlamp apparatus, and a second mode for swiveling the lamp units such that a shielded area created in the light distribution pattern follows the forward vehicle based on the position of the forward vehicle detected by the vehicle position detector,
