Abstract:
A lamp optical axis control system for a vehicle having a lamp with an optical axis for providing an illumination range in front of the vehicle, said control system comprising:vehicle speed detecting means for detecting a vehicle speed; steering angle detecting means for detecting a steering angle of a steering wheel; driver's viewpoint calculating means for providing a position of a driver's viewpoint a predetermined time in advance according to the vehicle speed and the steering angle, wherein said driver's view point calculating means comprises: a map for providing standard positions of the driver's view points that correspond to vehicle speeds and steering angles; and correcting means for correcting the standard position of said driver's viewpoint by multiplying said standard position by a prescribed coefficient proportional to the vehicle speed if the vehicle speed is different from said standard vehicle speed; and control means for controlling said optical axis according to the future position of the driver's view point, thereby moving said illumination range to cover said driver's viewpoint.
