Platooning protocol definition and communication strategy. D2.8 of H2020 project ENSEMBLE
report
This deliverable provides a specification of the V2X communication protocol to enable platooning using the wireless communication standard ITS-G5. The protocol specifies how vehicles inform each other about their ability to form a platoon, and which data has to be exchanged when executing the actual procedure of joining, driving in the platoon and leaving a platoon. It includes messages and how to exchange them to allow for the aforementioned situations. In ENSEMBLE, a new facilities layer protocol supporting the platooning application is developed. This makes use of already standardized lower layer protocols in ETSI TC ITS. The platooning protocol uses already available message types and signals, and where necessary new ones are introduced. The protocol logic for joining, platooning, and leaving has been derived from the use cases in deliverable D2.3 [27] and the requirements and specifications in deliverable D2.5 [28] of ENSEMBLE. The available security framework for cooperative intelligent transport system (C-ITS) in Europe is used for signing and verifying unencrypted messages to establish a trust domain. In addition, the security is extended with encryption of platoon application data. Deliverable 2.9 will specifically treat security in platooning. Deliverable D2.5 contains the lessons learned and future considerations on the communication protocol from the final testing of the seven-brand truck platooning in Spain taking place in September 2021. Deliverable D6.15 [34] will also provide guidance for the upcoming standardization on platooning.
