ABSTRACT
When the vehicels turns in curve at night, it can always appear “the blind spot” in the turn, for the lights are unable to adjust the illumination angle. In order to enhance safety driving at night, an adaptive front-lighting system (AFS) of automobile controlled by STC12C5A60AD which is the core of electric control unit is designed in this work. The AFS is based on the steering wheel angle and speed changes to adjust light axis angle to light up the road in the front, so the drivers' security vision are improved. The work principles of the AFS[6] and control model and hardware circuits are particularly described..
