汽车三维在线展示与虚拟试驾系统研究

目的针对在线汽车营销方式交互性、沉浸感差等问题,提升汽车网络化营销的交互体验性能。方法基于Unity3D平台,利用C#和My SQL数据库设计了汽车三维在线展示与虚拟试驾系统,采用显示层、应用层、数据层的三层体系结构,主要包含4个功能模块,分别为用户信息管理、汽车三维展示、虚拟试驾和试驾报告。依据SAEJ1100标准建立腿部空间测量模型,提出在虚拟试驾系统中腿部空间舒适性评价方法,并且基于实测数据构建虚拟试驾过程中的油耗预测模型。最终,建立较为真实的汽车试驾模型,同时确保试驾系统的流畅性和联机试驾的可操作性,实现系统的开发。实验验证系统的应用效果较好。结论汽车三维在线展示与虚拟试驾系统有效提高远程人机交互体验性能,为用户充分了解所选车型的特点和性能搭建了新型平台。

Automobile Three-dimensional Online Display and Virtual Driving System

Facing with the problem of lacking interactivity and immersion in online car marketing, it aims to improve the interactive experience of automotive network marketing. Based on the Unity3D platform, the auto 3D online display and virtual driving system is developed using C# and MySQL database system. It adopts a three-layer architecture (display layer, application layer and data layer) and includes four function modules (user information management, automobile 3D display, virtual test and auto test report). The leg space measurement model is established according to SAEJ1100 standard, and then the evaluation method of leg space comfort in the virtual test drive system is proposed. The fuel consumption prediction model in the virtual test drive process is constructed based on the data measured in real scenarios. Thus, a more real vehicle test drive model is established, ensuring the smoothness of the test drive system and the operability of the online test drive. The effective of proposed system is demonstrated by the experimental results. The auto 3D online display and virtual driving system could effectively improve the performance of remote interactive experience for users, and is helpful for fully understanding the characteristics and performance of the desired vehicle.
