Virtual Driving on Mountain Roads for Driving Simulators

针对山区道路模拟驾驶体验的特点,提出了模拟驾驶场景中预定义和路面感应计算相结合的实时控制虚拟车辆运行方法。在虚拟场景中预定义自走车辆运动轨迹,通过时间控制位置和方位的线性插补方法使其运行。对于驾驶车辆模型,文中用方向盘信号和车辆轮胎在路面的空间位置坐标实时计算车辆的位置和方位姿态,使车辆行驶与山区路面的坡度、弯道倾斜、粗糙度等状况等相吻合,增强了山区道路安全驾驶的真实体验感。

In view of the feature of the virtual driving experience on mountain roads, this paper puts forward a method of controlling the virtual vehicle in real time by predefining and calculating road surface induction. The traj- ectory of the vehicle is predefined in the virtual scene and the linear interpolation method of controlling position and orientation by time is adopted to make it run. For the driving model, this paper calculates the position and orienta- tion of the vehicle through the steering wheel signal and the space coordinate of tires in the ground, making the driv- ing suitable for the gradient slope and roughness of the road and thus improving the real sense of safe driving on the mountain road.
