The invention relates to a novel self-adaption lighting system for automobile headlamps. The novel self-adaption lighting system is mainly composed of a sensor unit, a central control unit and a drive execution unit, and meanwhile, communication inside and outside the system is performed by means of an LIN bus and a CAN bus. According to the invention, as multiple sensors are installed on the automobile, the current speed of the automobile and the cornering signal of a steering wheel are obtained in real time, and input into the control unit, the turning angles of the two headlamps are calculated by the central control unit, then a control command is transmitted to the drive unit through the LIN bus, thus the headlamps are driven by stepper motors to reach target locations, and the requirement of the curve self-adaption lighting system is met.
