The invention discloses a modular autonomous compliance steering device and a steering method for an automobile headlamp. The device comprises a rotary bracket, a lens assembly and a driving platform, wherein the lens assembly is rotationally arranged on the rotary bracket; and the driving platform is arranged on the rotary bracket and can drive the lens assembly to rotate on the rotary bracket. The method comprises the following steps: (1), a gyroscope and an acceleration sensor send sensed information to a microprocessor; (2), the microprocessor receives the sensed information sent by the gyroscope and the acceleration sensor respectively, calculates out a signal of an angle that the lens assembly is required to be rotated, converts the signal of the angle that the lens assembly is required to be rotated to a control signal and sends the control signal to a stepping motor driver; and (3), the stepping motor driver controls a stepping motor to work according to the control signal sent by the microprocessor. The device is simple in structure, adopts an integrated structure wholly, and very convenient to mount, so that the improvement difficulty and improvement cost of the headlamp are greatly reduced.
