The invention relates to a self-adjusting system of an automobile headlamp along with steering. The self-adjusting system is characterized by comprising an angle sensor, an electric control unit, a stepping motor, a gear transmission mechanism and a movable lampshade, wherein the angle sensor is arranged on a clock spring of an automobile steering column and can be used for detecting the rotation direction and the rotation angle of a steering wheel; the electric control unit is composed of a control circuit, a processor and a signal converter; the processor can be used for setting a transmission relation between the stepping motor and the gear transmission mechanism according to a movement proportion relationship between the steering wheel and wheels and calculating the rotation direction and the rotation angle of the stepping motor according to a signal sent by the angle sensor; a driver is integrated on the stepping motor and can be used for driving the gear transmission mechanism to drive the movable lampshade to rotate. The self-adjusting system disclosed by the invention realizes synchronous steering of the illumination direction of automobile lamps along with steering of the wheels, and is fast to response and high in reliability, and the driving safety is improved; the low-power stepping motor is low in energy consumption, and meanwhile, the science and technology feeling and the driving feeling are increased.
