Method and device for automatically adjusting electric control parameters of sewing machine and readable storage medium

The invention relates to a sewing machine electric control parameter automatic adjustment method and device and a readable storage medium, and the method comprises the steps: obtaining a thread end length parameter and a cloth stitch length optimization parameter; the motion amplitude of a transmission part of the sewing machine in the working state is detected, the transmission part and a machine needle of the sewing machine have the same motion period, and the motion amplitude of the transmission part and the stitch length value are in a proportional relation; determining a stitch length value of the sewing machine according to the motion amplitude; and according to the stitch length value, the thread end length parameter and the cloth stitch length optimization parameter, electric control parameters of the sewing machine are adjusted. By means of the sewing machine control method and device, the electric control parameters of the sewing machine are adjusted according to the stitch length value, the thread
