The growing interest in autonomous vehicle technology presents opportunities for manufacturers to pursue plans based on machine learning to develop their own self-driving solutions while maintaining their competitive edge. Collaborative artificial intelligence presents manufacturers with the possibility of cooperation without sharing private user data. Federated learning is a distributed machine-learning framework that enables multiple parties to cooperate on a common model while training locally on their own private data. Despite the similarities in the underlying technology, the application of federated learning for autonomous driving has attracted limited interest. Numerous challenges arise and need to be addressed: Different autonomous driving systems develop independently, and hence their models differ significantly. Vehicle manufacturers may use proprietary data formats that ensure the privacy of user data, and the necessary training data remain in the manufacturer domain. Communication efficiency is critical, as the resources of vehicles are constrained compared with fixed servers. Training data remain local, and agent-specific knowledge cannot be transferred directly.
Collaborative autonomous driving powered by federated learning could fill the perceptual gaps during periods of limited visibility and ensure the safe crossing of busy intersections. A federated-learning framework has been developed that integrates several key components and techniques for training across a multi-manufacture federated vehicular network. It transmits only key information that preserves the privacy of the drivers while enabling safe autonomous driving in a limited-visibility environment. Powers and constraints differ across manufacturers, so establishing a top-level data flow is also necessary.
