V2X METHOD FOR GENERATING ERROR CORRECTION DATA FOR V2X BASED VEHICLE SATELLITE NAVIGATION SIGNAL

摘要

The present invention comprises the steps of forming a network for generating error correction data for a satellite navigation signal by a plurality of roadside devices that transmit traffic information to a vehicle in motion using a wireless communication device; Generating state information in each of the plurality of roadside devices; Each of the plurality of roadside devices determining whether it is in a bad state by using the state information; Removing one or more roadside devices from among the plurality of roadside devices that determine their state as a bad state from the network; Rebuilding the network of the roadside devices other than the one or more roadside devices among the plurality of roadside devices; The master roadside device of the re-formed network generates first error correction information for the satellite navigation signal, and combines second error correction information of another roadside device included in the re-formed network with the first error correction information. Generating the error correction data; And broadcasting, by the master roadside device, the error correction data to the vehicle located in the service area of the re-formed network.
