The invention discloses an unmanned vehicle path planning method for a special scene in a 5G environment, and the method depends on an unmanned vehicle path planning system based on 5G communication.The path planning system comprises an unmanned vehicle, a road side unit, a cloud platform, and a 5G network. The method provided by the invention has the characteristics of a high transmission speed,more transmission information and high signal quality, can overcome a problem of special scene communication, and realizes efficient, stable and rapid information interaction among the unmanned vehicle, a road side unit and a cloud platform; through organic combination of historical information and real-time perception, computing resources occupied by the cloud platform in conventional operationare effectively reduced, and the safety and accessibility of unmanned driving are guaranteed; and the vehicle, the road and the cloud interact, all-time, all-weather, full-coverage and high-precisioncollaborative perception can be achieved, and a decision of path planning and adjustment is completed together so that the vehicle running efficiency is improved.
