Inter-vehicle communication systems using millimeter wave band - joint research and experimental activities on ITS at YRP

摘要

Interest in ITS (Intelligent Transport Systems) technology has been growing in recent years, because it may be used to alleviate problems such as traffic jams and traffic accidents. Wireless communications technologies form the basis of enabling ITS to be implemented and among related technologies, road-vehicle communication (RVC) and inter-vehicle communication (IVC) play important roles. In ITS, Inter-Vehicle Communications (IVC) have an important place in assisting safe, effective, and economical driving, as well as supporting automated driving such as Advanced Cruise-Assist Highway Systems (AHS). In these applications, the transmission quality of IVC can be a matter of life or death for many users. In addition, high speed data transmission such as moving pictures for entertainment will be required in the future. Therefore, high-quality communications media must be secured for IVC systems. This paper shows activities of joint research on Inter-Vehicle Communication (IVC) system using millimeter wave (60GHz) at Yokosuka Research Park (YRP). This joint research group discussed the technical standardization of the raillimeter-wave communication system for IVC, and developed an integrated millimeter-wave radar communication system for safe operational support and the fusion systems of SS radar and communication systems.
