摘要： A lamp system is provided. The lamp system includes a deflection angle calculating section configured to calculate a deflection angle of an irradiation direction of a lamp based on a steering angle of a steering wheel of a vehicle and a speed of the vehicle, a swivel control section configured to control the irradiation direction in accordance with the calculated deflection angle, a filter section configured to change an output response of a change of the speed of the vehicle to be input to the deflection angle calculating section, and a filter control section configured to compare the calculated deflection angle with a reference value and to control the filter section to change the output response in accordance with a result of the comparison.

摘要： 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.
