The invention discloses an automatic control module of an automobile steering lamp. The automatic control module is characterized in that the control module is a steering wheel angle sensor circuit and is used for detecting the rotating direction and angle of a steering wheel steering column, converting the rotating direction and angle of the steering wheel steering column into an analog signal, and sending the analog signal to a microprocessor control circuit; an automobile signal input circuit inputs a speed signal to the microprocessor control circuit after receiving the speed signal of an automobile speed sensor; the microprocessor control circuit calculates the sensor signal and the speed signal to calculate the relation between the automobile direction variable quantity and the given set value and sends the result to an automobile body control module, and the automobile body control module controls the on-off state of the steering lamp. By means of the structure, the steering lamp is automatically turned on under the situation that a driver does not turn on the steering lamp during steering and lane changing, traffic accidents caused by not accurately using the steering lamp can be effectively reduced, and the comfort and safety of automobile driving are improved. Excessive cost does not need to be added, and the automatic control module is suitable for being used in low-price automobile types.
