UML-based design of intelligent vehicles virtual reality platform

Combining virtual reality (VR) technology with Automated Highway System (AHS) simulation could not only show visually comprehensible results but also reduce the cost when it is no longer necessary to test with real vehicles. This paper presents an intelligent vehicles virtual reality (IVVR) platform, which is an interdisciplinary software application of VR & AHS. It aims at the control algorithm design and verification for intelligent vehicles. Firstly, the design of IVVR platform is implemented by several UML functional diagrams; then, software technology as well as its realization methods are presented; finally, some intelligent vehicles behaviors simulations like maintenance of a secure inter-vehicular distance or lane-change are experimented in IVVR platform and real-time animation could be obtained with good performance besides the figures and data.
