Abstract

The vehicle information sharing method comprises the steps that each vehicle carries out license plate identification on surrounding vehicles, and meanwhile, the vehicle basic information of the vehicle and the acquired basic information of the surrounding vehicles are broadcasted regularly. Each vehicle may generate a dynamic vehicle topology map centered on each vehicle based on the received data packet content. The invention also provides a device for realizing the method. The invention can enable the vehicles to share the basic information of the vehicle and the acquired information of the vehicle.
