The embodiment of the invention discloses a collision early warning method and device, an automobile and a medium, and belongs to the technical field of automobiles. The method comprises the steps that obstacle detection is conducted on the area where a first automobile is located, and first position information is obtained; receiving second position information sent by a second automobile; under the condition that the first automobile is in the backing state, the distance between the first automobile and surrounding obstacles is determined based on the first position information and the second position information; and collision early warning is carried out based on the distance between the first automobile and the surrounding obstacles. According to the method, the first automobile can determine the surrounding obstacles of the first automobile as much as possible, whether the first automobile collides with the surrounding obstacles or not can be determined according to the distance between the first automobile and the surrounding obstacles, collision early warning is carried out, the situation that the first automobile collides in the reversing process is avoided, and the safety of the automobile is improved. The accuracy of collision early warning is ensured, and then the occurrence frequency of car backing collision accidents is reduced.
