Architecting peer-to-peer trajectory negotiation with sub-millisecond convergence across multi-brand autonomous truck platoons.
Autonomous vehicle platoons achieve aerodynamic efficiency and roadway throughput by maintaining ultra-short headway distances. However, string stability and emergency braking require deterministic state agreement across peer vehicles without relying on centralized cellular infrastructure.
V2Swarm leverages optimized Byzantine Fault Tolerant (BFT) protocols executed over 5G NR sidelink (PC5). Each vehicle continuously broadcasts its projected 3-second trajectory envelope, velocity vectors, and braking reserve. The consensus engine evaluates candidate trajectories against physical clearance envelopes, arriving at mathematically proven collision-free paths within 1.2 milliseconds. ``` +-----------------------+ PC5 Broadcast +-----------------------+ | Swarm Leader (Pilot) | --------------------------------> | Following Vehicle #1 | | Trajectory Envelope | <-------------------------------- | Trajectory Envelope | +-----------------------+ Distributed BFT Consensus +-----------------------+ | | +----------------------------+-------------------------------+ | v Synchronized Braking & Spacing ```
During 100-km autonomous highway evaluations, V2Swarm maintained stable 0.4-second inter-vehicle spacing at 90 km/h with zero phantom oscillations and guaranteed safety margins during sudden cutoff maneuvers.
