說明書
The present disclosure relates to a communication system, and more particularly to a hybrid on board unit and a roadside unit supporting WAVE-V2X and C-V2X.
V2X refers to exchanging information with other vehicles and objects where infrastructures are established such as roads or the technology thereof. V2X consists of four types of communication: Vehicle to Vehicle (V2V), Vehicle to Infrastructure (V2I), Vehicle to Pedestrian (V2P) and Vehicle to Network (V2N). V2X is a base technology for future automobiles that will be safe and connected via communication, and a core technology that will enable completely automated transportation infrastructures.
As the V2X technology market expands, major companies and research groups of various countries are conducting researches for technology development and technology standardization in order to gain the upper hand in the autonomous vehicle market. Communication standard technologies for V2X include Wireless Access in Vehicular Environment (WAVE) of the DSRC method and LTE V2X of the cellular V2X (C-V2X) method. The WAVE and C-V2X have different protocol stacks, and their methods of modulating data are different as well, and thus a WAVE terminal cannot process C-V2X signals, and a C-V2X terminal cannot process WAVE signals either.
