Using the predictive information on ITS, Automated Driving Systems shall be realized and expedited.
(From the Cabinet Office )
Automated Driving Systems is the most practical technology toward the advanced safety road society.Cooperative Automated Driving Systems need the sophisticated and enhanced V2V, V2I communication technology.
This project supports the establishment of this technology.
Vehicle to Infrastructure communication
Vehicle to vehicle communication
Background and Aims of the Research and Development
Target
Under the real situation, V2V, V2I communication is achieved
to the practical level for the automated driving systems.
R&D theme
<Contractors>
Implementation system
Theme 1. Development of V2V, V2I communication technology needed for automated driving systems
Research Theme and Targeta) The study of communication in the cooperative system (V2V, V2I)
>Communication performance at the heavy traffic jam is evaluated in the specific area.(Evaluated by the real measurement and the simulation)
b) The study of service in the cooperative system (V2V, V2I)>Service function is evaluated in the information overlapped and confliction.
c) The study of promotion and penetration>Function feature is evaluated by the low price common devices, and
effects and values are verified by the emergency motor vehicle.
d) The study of communication in the automated driving system >Decentralized coordination technology shows the high reliable and low latency.
