Virtual Reality for Collaborative Design Review and Learning in Hydrogen Vehicle Architecture

Abstract

Virtual reality (VR) technologies have shown significant potential in enhancing the automotive design process by providing immersive, interactive, and collaborative environments for reviewing complex vehicle architectures. Traditional CAD models and physical prototypes often struggle to offer the flexibility needed for rapid iteration and spatial understanding, especially for systems such as hydrogen-powered commercial vehicles. This study aims to develop a VR platform to improve the collaborative review of the internal architecture of a hydrogen-powered commercial vehicle, specifically focusing on the spatial arrangement and interaction of critical components such as hydrogen tanks, fuel cells, and batteries. The goal is to enhance design processes, reduce iteration costs, and improve spatial understanding and decision-making within automotive teams. The VR environment was built using Unity 3D and optimized for mobile VR platforms, incorporating features such as interactive component manipulation, dual locomotion modes (teleportation and free movement), and real-time collaboration. The platform was tested with a range of users, including automotive professionals and students, to evaluate its usability, performance, and impact on spatial understanding and user engagement. User feedback demonstrated high levels of satisfaction, with 85% of participants reporting improved spatial understanding, 80% preferring VR over traditional CAD tools, and 90% noting increased engagement. The VR platform enabled faster completion of assembly tasks (40% faster than traditional methods) and improved collaborative decision-making. However, challenges such as system performance issues, motion sickness, and a steep learning curve were reported by some users, particularly nontechnical users. The VR platform developed in this study significantly advanced the collaborative and immersive review of automotive designs, offering tangible benefits in terms of engagement, spatial comprehension, and design iteration efficiency. While there were limitations related to hardware requirements and user accessibility, the results highlight the transformative potential of VR in automotive design and education. Future work will focus on performance optimization, AR integration, and improving usability for nontechnical users.
