Digital Twin for Safety Validation and Crash Scenario Simulations

Ensuring safety and reliability is paramount in the development of Autonomous Vehicles (AVs). Digital Twin (DT) technology provides a dynamic virtual counterpart to real vehicles, enabling scenario-based safety validation and crash simulations without physical risk. This chapter explores how DTs integrate real-time sensor data, AI-driven analytics, and multi-physics modeling to simulate complex collision dynamics and evaluate vehicle responses. Emphasis is placed on aligning DT testing with international standards such as ISO 26262 and SOTIF. Case studies from BMW and Waymo demonstrate the industrial application of DTs in reducing prototyping costs and improving validation accuracy. Challenges including data veracity, synchronization latency, and computational overhead are also discussed. By leveraging emerging technologies like quantum computing and federated learning, DT-based safety validation can ensure scalable, transparent, and ethically responsible deployment of autonomous vehicles.
