Abstract :
This paper analyzed photometric characteristics of vehicle headlamps when turning the corner, and developed a new kind of AFS (adaptive front-lighting system) based on CCD (charge-coupled device) which was better than traditional AFS. This new AFS used CCD image sensor to detect information about the corner and then sent curvature radius to electronic control units in advance. Meanwhile, electronic control units would calculate accurate rotation angle of headlamps through velocity and curvature radius, and send it to motor to adjust headlamps to get the lighting beam which was suitable for the corner. Through this way, it could avoid "blind spot" caused by the fixed lighting area when coming into the corner, and improve driving safety. This paper gave a modeling for horizontal rotation angle of vehicle headlamps, and simulated it with MATLAB.
