六自由度汽车驾驶模拟器视景仿真系统研究

The presence research of automobile driving simulator

搭建了汽车驾驶模拟器运动平台,对其系统组成进行了详细介绍,采用先进的视景仿真软件——OpenGVSSDK和Mu ltiGen Creator,并结合面向对象技术设计与开发了汽车驾驶模拟器大规模真实感视景系统,动画频率能达到60帧/s。;采用六自由度运动平台为驾驶学员提供了在坡路、颠簸路面等以及车辆加减速、转向、侧滑时的运动临场感。测试结果表明,所建立的汽车驾驶模拟器系统能够满足汽车驾驶培训的要求,且具有良好的真实沉浸感。

In this paper, a automobile driving simulator is developed, and the structuring of the system is introduced in great details. The visual system with large - scale and high - quality of automobile driving simulator is developed based on advanced simulation software（ OpenGVS SDK and MultiGen Creator） combining with the Object -Oriented method. The frequency of the animation reaches to 60 frames per second by experiments. A 6 -degree -of- freedom （DOF） motion base is introduced to provide the realistic motion presence during the time of automobile＇s driving along the sloping and bumpy roads as well as speed - up, speed - down, turn - aside and sideslip. The validity of this method has been confirmed experimentally. Namely, the automobile driving simulator can be fit with the need of driving training with satisfying reality and immersion.
