COMMUNICATION METHOD AND SYSTEM FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2011/046405
Kind Code:
A2
Abstract:
A communication system for a vehicle on a section of a roadway, the system comprises a vehicle communication unit installed on the vehicle, the vehicle communication unit wirelessly communicates through a magnetic field signal; a plurality of roadway communication units disposed under a surface of the roadway within the section, each roadway communication unit wirelessly communicating with the vehicle communication unit through the magnetic field signal and outputting a first data including an information on a speed of the vehicle; and a gateway node disposed at the roadway, communicating with the roadway communication units and outputting a second data. The gateway node receives the first data from the roadway communicating units, estimates a location where the vehicle reaches at a preset moment by using the speed of the vehicle, and controls one or more of the roadway communication units near the estimated location such that said one or more of the roadway communication units wirelessly transmit the second data to the vehicle.
