Vehicle headlight system

A vehicle headlight system, comprising:

• a lamp unit including a high beam module, and configured to be attached to a right and left front of a subject vehicle, and the high beam module of the lamp unit including
• a projector lens having an optical axis, an incident surface and a first focus located on substantially the optical axis of the projector lens,
• a light source configured to emit light, and located on substantially the optical axis (AX) of the projector lens, wherein the first focus of the projector lens is located between the light source and the incident surface of the projector lens,
• a first reflector configured to reflect the light emitted from the light source toward the first focus of the projector lens,
• a movable shade extending from substantially the first focus of the projector lens in a direction of the first reflector at a substantially right angle with respect to the optical axis of the projector lens, and including a first shading plate, a second shading plate and a shading width located the first shading plate and the second shading plate, and configured to vary the shading width,
• a first supporter connecting the projector lens, the light source, the first reflector and the movable shade, and
• a rotary shaft included in the first supporter, and an extension of the rotary shaft intersecting with the optical axis of the projector lens at a substantially right angle;
• a camera having an optical axis being located adjacent the subject vehicle, configured to photograph at least one pedestrian and at least one forward vehicle located in a frontward direction of the subject vehicle, and the camera being configured to output the at least one pedestrian and the at least one forward vehicle photographed by the camera as image data;
• an image processing circuit configured to detect the at least one pedestrian and the at least one forward vehicle in accordance with the image data output from the camera, configured to generate human locating data of the at least one pedestrian and vehicle locating data of the at least one forward vehicle with respect to the optical axis of the camera, and being configured to output the human locating data and the vehicle locating data vehicle as human data and vehicle data, respectively;
• a system controller including a pedestrian detector, a forward vehicle detector, a swivel setter, a shading width setter and a light-emitting controller,
• the pedestrian detector configured to input the human data output from the image processing circuit, and configured to determine whether the at least one pedestrian exists or not in accordance with the human data,
• the forward vehicle detector configured to input the vehicle data output from the image processing circuit, and configured to determine whether the at least one forward vehicle exists or not in accordance with the vehicle data,
• the swivel setter configured to configured to input the human data output from the image processing circuit, and configured to determine a turning angle of the rotary shaft of the high beam module as swivel data in accordance with the human data, and configured to output the swivel data,
• the shading width setter configured to configured to input the human data output from the image processing circuit, and configured to determine the shading width of the movable shade as shading data in accordance with the human data, and configured to output the shading data, and
• the light-emitting controller configured to input a rudder signal, a speed signal and a switching signal output from the subject vehicle, configured to generate a light-emitting driving signal in accordance with the rudder, the speed signal and the switching signal, and configured to output a light-emitting driving signal to the lamp unit;
• a swivel structure configured to input the swivel data output from the swivel setter of the system controller, and configured to rotate the rotary shaft of the high beam module of the lamp unit in accordance with the swivel data;
• and
• a shading driver configured to input the shading data output from the shading width setter, and configured to set up the shading width of the movable shade of the high beam module of the lamp unit.
