Lighting apparatus for vehicle and method of controlling a headlamp |
摘要 |
A lighting apparatus for a vehicle includes headlamps configured to be switchable between high beam and low beam, wherein a direction of an optical axis of each of the headlamps is variable in a substantially horizontal plane by use of a swivel actuator and a controller configured to control the headlamps, wherein if the controller detects a forward vehicle in projection areas of the headlamps, the controller temporarily switches from the high beam to the low beam, then drives the swivel actuator toward a target swivel angle according to a position of the detected forward vehicle and, after finishing driving toward the target swivel angle or during driving toward the target swivel angle, starts projection by the high beam. |
