摘　　要：基于虚拟车辆坐标和车辆运动状态对比实现了车辆运动控制方法,通过研究车辆自由行驶、跟驰和变道实现了车辆的虚拟车辆相应的运动策略,利用Vega Prime相关碰撞检测机制,实现了车辆信号控制,并在Vega Prime平台上使用VC++编程实现了虚拟车辆的智能运动模拟,最后采用北京五道口区域交通流实际算例验证了模拟方法的有效性.研究结果表明:通过对Vega Prime进行二次开发,可以实现高沉浸感、高人机交互的虚拟车辆智能运动模拟,模拟仿真结果与交通实际情况相符.The vehicle motion control method is realized based on the coordinates of the virtual vehicle and vehicle motion state. Based on the research of free-driving, car-following and changing-lanes, virtual vehicle movement strategies are implemented. The vehicle signal control is achieved by using collision detection mechanism in Vega Prime. The intelligent motion simulation of virtual vehicle is accomplished with VC＋＋ under the platform of Vega Prime. Finally, the proposed simulation method is verified by a real instance of regional traffic flow at Wudaokou in Beijing. The results show that it can achieve virtual intelligent vehicle motion simulation with high immersive and high human-computer interaction. The simulation results are consistent with the actual traffic situation.
