TOKYO -- Nissan Motor will begin testing connected cars on public roads in Japan this year, partnering with five companies to accelerate efforts to develop safer self-driving technologies.
The project aims to verify the reliability and other aspects of the Cellular Vehicle-to-Everything standard. The V2X standard is designed to enable high-speed data sharing among automobiles, road infrastructure and digital devices carried by people.
Such data communications are expected to improve traffic safety. Connected vehicles on the road can share data among each other, letting one automobile obtain information about what lies beyond a blind spot from the cameras and radars of other cars. V2X was devised by the 3rd Generation Partnership Project, a cellphone technology standardization organization.
Test participants will include leading Japanese mobile phone carrier NTT Docomo, major German autoparts maker Continental, Swedish telecom company Ericsson, Japan's Oki Electric Industry and U.S. chipmaker Qualcomm.
Nissan will determine the procedures and other details of the tests, while Docomo provides the data communications platform. Continental and Qualcomm will cooperate in developing onboard communications systems for vehicles.
V2X is competing with the Dedicated Short Range Communications service to become the global communications standard for future connected cars. The DSRC technology already has been used in applications such as electronic toll collection on Japanese highways.
