V2X-based vehicle-road cooperation method and V2X-based vehicle-road cooperation system

Abstract

The invention provides a V2X-based vehicle-road cooperation method and a V2X-based vehicle-road cooperation system. The V2X-based vehicle-road cooperation method comprises the following steps of collecting first data information of a first vehicle through a second vehicle; collecting second data information of the first vehicle through a V2X communication module, and fusing the second data information and the first data information to form vehicle information; uploading the vehicle information to a cloud end, and sharing the vehicle information to the rear vehicle in real time by the cloud end; and the rear vehicle cooperatively completing a driving decision according to the vehicle information. The V2X-based vehicle-road cooperation method can fuse the first data information collected bythe second vehicle and the second data information collected by the V2X communication module; the information transmission blind area is eliminated, the fused vehicle information can be shared to rearvehicles, the rear vehicles can cooperatively complete driving decisions according to the fused vehicle information, and chain accidents of the rear vehicles are avoided.

Description

technical field [0001] The present invention relates to the technical field of vehicle networking and assisted driving, in particular to a V2X-based vehicle-road coordination method and a V2X-based vehicle-road coordination system. Background technique [0002] V2X (meaning vehicle to everything, that is, information exchange between vehicles and the outside world) is the key technology of the future intelligent transportation system. It enables communication between vehicles, vehicles and base stations, and base stations and base stations, and effectively obtains real-time road conditions and road information. , Pedestrian information and a series of traffic information, which can improve driving safety, reduce congestion, improve traffic efficiency and provide in-vehicle entertainment information, etc. Based on strong cellular network coverage, it can greatly reduce the cost of future autonomous driving and Internet of Vehicles deployment. [0003] Different from sensors s...

AI Technical Summary

Problems solved by technology

[0007] 2. The existing technology only monitors the vehicles in front through sensors such as cameras and radars, and there is a certain blind spot in the field of vision

[0008] 3. The existing technology is only for the monitoring of a single vehicle in front, and the continuous rear vehicles cannot obtain the front information

[0009] 4. In the existing technology, the speed of uploading the collision accident information to the cloud is relatively slow
