Abstract

The present disclosure provides a road information correction method, apparatus, and system based on vehicle-to-everything (V2X). The method includes: sending a road information map to a first vehicle, such that the first vehicle obtains first original road information by using the road information map, and collects real-time road information; receiving the real-time road information uploaded by the first vehicle; determining, according to the real-time road information, whether the stored first original road information needs to be corrected; and if yes, correcting the stored first original road information according to the real-time road information; otherwise, not correcting the stored first original road information. According to the embodiments of the present disclosure, road information stored in a cloud can be corrected in a timely manner, and fast-changing information and slow-changing information can be identified to provide different determining mechanisms for the two, thereby ensuring precision of correcting road information.
