Vehicle anti-collision method and device

The invention discloses a vehicle anti-collision method and device, belonging to the technical field of communication. The method comprises the steps of acquiring the instant point location coordinate of a vehicle which has an accident and the instant point location coordinate of a vehicle which runs at present; determining the relative position information of the vehicle which has the accident and the vehicle which runs at present according to the instant point location coordinate of the vehicle which has the accident and the instant point location coordinate of the vehicle which runs at present; and judging whether the vehicle which runs at present has a risk of accident or not according to the relative position information. The device comprises an acquisition module, a determination module and a judgment module. Since whether the vehicle which runs at present has the risk of accident or not is judged according to the relative position information of the vehicle which has the accident and the vehicle which
