摘要:

在这项工作中,我们探索了一种基于数据驱动的学习方法,用于学习小型自动驾驶车辆的运动动力学模型,并观察其对运动规划(特别是自主漂移)的影响。在现实世界中执行运动规划时,存在许多误差来源,计划的内容往往与实际车辆上执行的内容不一致。基于惯性测量和执行命令学习运动动力学规划器,可以帮助我们学习世界状态。在我们的案例中,我们关注漂移领域;这是一种复杂的机动,需要足够光滑的路面、足够高的速度以及速度的剧烈变化。我们尝试学习这些漂移机动的运动动力学模型,并尝试收紧车辆的滑移。我们的方法能够学习用于高速圆形导航的运动动力学模型,并且能够通过修正执行曲率来应对松散漂移,从而在高速自主漂移中避开障碍物。我们寻求在未来的工作中调整我们的运动动力学模型,以在更紧凑的漂移中取得成功。

英文摘要:

In this work, we explore a data-driven learning-based approach to learning the kinodynamic model of a small autonomous vehicle, and observe the effect it has on motion planning, specifically autonomous drifting. When executing a motion plan in the real world, there are numerous causes for error, and what is planned is often not what is executed on the actual car. Learning a kinodynamic planner based off of inertial measurements and executed commands can help us learn the world state. In our case, we look towards the realm of drifting; it is a complex maneuver that requires a smooth enough surface, high enough speed, and a drastic change in velocity. We attempt to learn the kinodynamic model for these drifting maneuvers, and attempt to tighten the slip of the car. Our approach is able to learn a kinodynamic model for high-speed circular navigation, and is able to avoid obstacles on an autonomous drift at high speed by correcting an executed curvature for loose drifts. We seek to adjust our kinodynamic model for success in tighter drifts in future work.
