The invention discloses an adaptive front turn lamp lighting system. A 2D or 3D acceleration transducer is respectively installed on the lamp and the rotor shafts of the front wheels of a car to measure the angle changes of the car and the front lamp in up, down, right and left directions, and then the turning angles of the front lamp in up, down, right and left directions are calculated through ECU integration, and the turning of the front lamp is controlled by a lamp turning drive and control module, thereby guaranteeing that the illumination of the front lamp in up, down, right and left directions can be correctly adjusted whether the car is in an upslope state or downslope state, accelerates or decelerates, or drives on an uneven road or makes a turn, so that the driving safety of the car is enhanced; the invention also reduces the complexity of the structure of an AFS system and realization cost and improves the transportability of the components in the system; besides, the system also reduces the possible maintenance cost of users and increases the possibility of being popularized for use.
