摘　　要：提出了一种基于虚拟现实仿真技术的汽车性能虚拟测试系统实现方案。采用3D技术构建测试对象模型及测试场景;利用虚拟现实工具Virtools的building blocks(BB)脚本语言进行逻辑编程,实现对象物理化、碰撞检测、动态跟踪、测试数据实时处理等系统关键技术;并结合数据库技术使试验数据管理更加方便安全;利用测试平台对东风标致307进行了车辆动力性能仿真测试,测试结果与实际情况相近,初步验证了测试平台的可行性。A virtual test system for vehicles was designed, based on virtual reality technology. The digital vehicle model and test scenarios were built with 3D technology; Logical programs were made by building blocks （BB） scripting language of Virtools, a virtual reality tools. The key technologies were realized, such as object collision detection,dynamic tracking, real-time data processing technology and so on; Combining with database technology made data management more convenient and safe . With Dongfeng Peugeot 307 as the object, the power performance was tested and the result was similar with the actual situation and verified the feasibility of the test platform.
