The invention discloses a vehicle early warning method and device. The method comprises the following steps: acquiring lane line information in a tunnel area; after obtaining the signal intensity of the beacon node information, calculating vehicle information in the tunnel area according to the signal intensity and the beacon node information; wherein the beacon node information comprises position information of a road side unit in the tunnel area; and when the vehicle in the tunnel area is judged to be in an abnormal driving state according to the lane line information and the vehicle information, sending early warning information to the vehicle in the abnormal driving state. By adopting the embodiment of the invention, the driving safety of the vehicle in the tunnel can be improved, and the possibility of accidents is reduced.
