摘　　要：为实现汽车运动性能优化,从汽车动力学角度出发,对汽车动力传动模型进行简化和分析,建立了汽车起步,换挡和制动过程的数学模型,并利用虚拟现实仿真软件,建立了汽车运动速度控制三维虚拟实验系统。系统首先建立了虚拟三维驾驶场景和汽车几何模型。然后通过控制罗技方向盘G27的离合器踏板、制动踏板、加速踏板和换挡操纵手柄作为系统输入,得到车辆不同条件下的运动状态。最后在虚拟环境中驱动汽车按照建立的数学模型运动,实现了汽车运动性能优化。In order to simulate the motion of the vehicle, a vehicle driving model was simplified and analysis. The mathematical models of vehicle starting, shifting and braking processes were established,. Then the virtual reality simulation software was used to build the 3D virtual experiment system for the vehicle velocity control. The we first established the three-dimensional virtual driving scene and vehicle geometric model. Then the inputs, including the clutch pedal, the brake pedal, the accelerator pedal and shift control handle, were provided by Logitech G27, and the motion state of vehicle under different conditions were computed with the computed motion mathematical model. Finally, we simulated the car movement in the virtual environment with Vega, and the high fidelity simulation of vehi- cle movement situation was realized.
