Design of 5G Vehicle-road-cloud Collaborative Architecture for Vehicle Platooning

This paper presents an architecture design of vehicle-road-cloud collaboration based on a 5g communication network, which supports vehicle platooning and applies it in the case of vehicle formation crossing the border. The architecture includes roadside, cloud systems, 5g network, and infrastructure deployment connecting vehicles, as well as specifications for interfaces of automated vehicles (network communication interface specifications and application interface specifications). In addition, solutions and simple tests are proposed for the cross-border problems in the case of vehicle platooning crossing the border, mainly including interconnection delay between PLMNs, and low delay communication between leader and team members' vehicles and roadside infrastructure.
