Abstract
A vehicle warning method, to avoid misjudgment caused by factors such as map precision and lane infringement of a vehicle, thereby improving warning accuracy. The method includes: A vehicle-to-everything V2X device receives a V2X message corresponding to a first vehicle. The V2X device determines, based on the V2X message, whether the first vehicle is in a warning area. The warning area is determined based on vehicle information of a second vehicle. The vehicle information includes at least position information of the second vehicle and a vehicle size of the second vehicle. The V2X device outputs warning information corresponding to the first vehicle to the second vehicle.

A vehicle warning method, comprising:
- receiving, by a vehicle-to-everything (V2X) device, a V2X message corresponding to a first vehicle;
- determining, by the V2X device, a warning area based on vehicle information of a second vehicle, wherein the vehicle information comprises position information of the second vehicle and a vehicle size of the second vehicle;
- determining, by the V2X device based on the V2X message, whether the first vehicle is in the warning area;
- and
- outputting, by the V2X device, warning information corresponding to the first vehicle to the second vehicle;
