Study for V2X Communication for Cooperative Driving Automation

Abstract

The concept of cooperative driving automation has been studied by corporations and research institutes for some time. Field operational tests (FOTs) and standardization activities for the communication protocols that will realize this functionality are also underway. In Japan, ITS wireless communication has been commercialized and is already used to support driving safety. Expanding it to automated driving can be envisioned. However, while the feasibility of its application and the communication protocols to adopt in the future, has been pursued by individual organizations, there have been no discussions for Japan as a whole. Since SIP has established a structure uniting industry, government and academia under one roof to work toward the realization of automated driving, it was decided to hold discussions under that framework. The Task Force (TF) on V2X communication for Cooperative Driving Automation was established in 2019 and initiated a 3-year plan to study future communication protocols. The TF defined use cases for assessing communication, and used them as a basis to clearly define communication requirements and study protocols that satisfy those requirements. The goal is to propose communication protocols for cooperative driving automation and formulate a roadmap that clearly indicates when they will be required.
