摘要:

自动驾驶中的轨迹规划高度依赖于预测其他道路使用者的涌现行为。基于学习的方法目前在基于仿真的挑战中展现出令人印象深刻的结果,其中基于Transformer的架构在技术上处于领先地位。然而,最终需要在现实世界中进行预测。除了从仿真到现实世界的转变之外,许多车辆特定和国家特定的差异,即传感器系统、融合与感知算法以及交通规则和法律方面的差异,也已提上日程。由于能够同时覆盖所有系统设置和设计域的模型尚不可预见,模型自适应发挥着核心作用。因此,基于一个Transformer模型,开展了一项关于迁移学习技术的仿真研究。此外,该研究旨在提供关于计算时间与性能之间可能权衡的见解,以支持向现实世界的有效迁移。

英文摘要:

Trajectory planning in autonomous driving is highly dependent on predicting the emergent behavior of other road users. Learning-based methods are currently showing impressive results in simulation-based challenges, with transformer-based architectures technologically leading the way. Ultimately, however, predictions are needed in the real world. In addition to the shifts from simulation to the real world, many vehicle- and country-specific shifts, i.e. differences in sensor systems, fusion and perception algorithms as well as traffic rules and laws, are on the agenda. Since models that can cover all system setups and design domains at once are not yet foreseeable, model adaptation plays a central role. Therefore, a simulation-based study on transfer learning techniques is conducted on basis of a transformer-based model. Furthermore, the study aims to provide insights into possible trade-offs between computational time and performance to support effective transfers into the real world.
