  • 关于 MotionDesk 的所有成功案例


了解仿真系统行为的最好方法是使用真实 3D 场景中的动画可视化技术。通过将仿真系统与实时动画相结合可以对全局有一个很好的掌控。由于动画可以被记录和回放,因此可以轻松采用覆盖技术比较不同的控制器开发策略。MotionDesk 使三维世界机械对象的运动实现了可视化,从而优化了 dSPACE 工具链。MotionDesk 是直观地了解任何类型的车辆动力学概念和驾驶操控(比如变换车道、split-µ 表面制动和转向等)的理想工具。


通过在虚拟环境中实现仿真场景的高精度可视化,MotionDesk 能帮助您充分发挥 HIL 仿真器的价值。利用您自己选择的图形视角和渲染模式,可以让 MotionDesk 从 HIL 仿真器中读取数据并且实时地显示运动对象(比如车辆、车轮、方向盘等)的动画,从而让您对仿真对象的实际行为有一个清楚的认识。您可以将动画另存为实验文件并记录视频文件,以对您的开发进行记录和说明。


MotionDesk 为高级驾驶辅助系统 (ADAS) 提供全方位的更好支持,必须对该辅助系统进行可视化才能了解操作的复杂性。对高级驾驶辅助系统进行测试时,可视化必须足够真实才能识别对象,同时,高帧频显得至关重要。

MotionDesk 渲染引擎可确保可视化过程既详细又真实。即使复杂的场景也能以 60 帧/秒的稳定帧频进行渲染。
