Human Body Models - Opportunities and Challenges for Reclined Occupants

October 9, 2025 | Adapting to Autonomy

Computational Human Body Models (HBMs) have the potential to revolutionize how we think about vehicle safety. Unlike traditional crash test dummies, HBMs offer detailed, anatomically accurate representations of the human body, enabling a deeper understanding of human responses to impact. As vehicles become more autonomous and flexible, new safety challenges emerge—such as novel seating arrangements or new crash scenarios. HBMs are uniquely suited to address these through high-fidelity simulation and injury prediction.

However, HBMs are still fundamentally research and development tools. To fully realize their potential, ongoing work is needed to improve their biofidelity, robustness, and applicability across use cases. This includes efforts to expand the model’s validation library, enhance injury prediction capabilities, and improve computational efficiency. This presentation will discuss the past development, current state, and future direction of computational HBMs, drawing from recent work in collaboration with automotive industry partners.
