Enabling safe & secure connection to an in-vehicle network (IVN)

In this paper, we present Vehicle Station Gateway (VSG) and Unified Gateway Protocol (UGP) for accessing vehicle bus data from smart car applications. They have been proposed and discussed as part of the ISO Standard Projects in ISO TC204 & TC22. We evaluate the feasibility of these approaches with a prototype implementation of vehicle trouble diagnosis and vehicle body network control applications with smart devices.

Analysis of UGP to achieve compatibility with Cooperative ITS station

In this paper, we analyze and propose modifications of UGP (Unified Gateway Protocol) to achieve compatibility with Cooperative ITS station architecture (ISO 21217). The UGP and vehicle station gateway (VSG) standard is for accessing vehicle bus data from smart car and cooperative ITS applications. They have been proposed and discussed as part of the ISO Standard Projects in ISO TC204 & TC22. We analyze the UGP and the Facilities in cooperative ITS station and propose modifications of additional procedures for ITS-S profile selection and SAPs (Service Access Points).

Practical experiences on a road guidance protocol for intersection collision warning application

In this paper, we provide an overview on a standardization activity in ISO TC204 WG17 for ISO 13184 series and discuss how to develop the Road Guidance Protocol (ISO 13184-2) and deploy it for the road safety use cases implementation based on V2X using the Personal ITS-Station. We have a standardization activity to specify the protocol which is designed to be flexible and extendable, which enables to add or delete Cooperative ITS use cases conveniently. Also we had a field trial of the RGP applied CAVG (Cooperative Autonomous Vehicle Guidance) system at a three-legged intersection as a test site and verified the RGP between the VGSS (Vehicle Guidance Server Subsystem) and the VGTS (Vehicle Guidance Terminal Subsystem) to periodically exchanges information (e.g., position, moving speed, direction, collision-possible and so on) using WAVE/DSRC technology.
