The invention relates to the field of vehicle steering control, in particular to a distributed electric drive electronic differential control method and device, electronic equipment and a medium. The distributed electric drive electronic differential control method comprises the steps that according to four-wheel reference steering angles and additional factors, four-wheel actual steering angles are determined; the additional factors comprise a road adhesion coefficient and/or a tire slip rate; determining a steering mode according to the reference vehicle speed and the preset vehicle speed; according to the actual steering angles of the four wheels, the reference vehicle speed, the steering modes, the vehicle mass center steering radius expressions in different steering modes and the steering radius expressions of the four wheels in different steering modes, the target wheel speeds of the four wheels are determined; and correcting the four-wheel speed according to the four-wheel target wheel speed and the four-wheel reference wheel speed. According to the invention, the wheel speed of four wheels can be accurately calculated and corrected, so that the actual motion trail of the vehicle is more consistent with the ideal target trail.
