If every vehicle in a platoon establishes bi-directional communication with each other by exchanging acknowledgements, functionality and flexibility of the platoon will increase considerably. For example, in case of merging traffic, vehicles cooperatively increase the gap in between them in order to accommodate vehicles in the next lane. In this paper, we suggest an efficient method for bi-directional communication assurance and platoon organization for cooperative vehicle platooning by group communication. Vehicles establish a communication group and bind vehicle IDs and correspondent ACKs into packets, where vehicles may use the short ID with ID conflict clearance. When communication situation change is occurred, each vehicle autonomously reacts to the change as needed. This indirect collaboration realizes a stable re-organization of the platoon without any conflict of commands. We describe the major idea with a simple state flow diagram and discuss simulation methodology for checking integrity of the system behavior.}, title = {協調的隊列走行のための車群通信技術の検討}, year = {2010} }
