摘要:

自动驾驶汽车需要了解他们目前拥有的能力。技能图是有向无环图,其中车辆的能力和这些能力之间的依赖关系被建模。飞行器所需的技能取决于飞行器必须执行的行为和飞行器的操作设计域(ODD)。技能图最初被提出用于在线监控自动驾驶汽车的当前能力。他们也被证明是有用的,在其他部分的发展过程中,如系统设计,系统验证。技能图构建是一个迭代的、基于专家的手动过程,几乎没有指导方针。因此,该过程容易出现错误和不一致,特别是关于将车辆的预期ODD中的变化传播到技能图中。为了规避这个问题,我们建议正式专家知识技能图建设成一个知识库和自动化的建设过程。因此,车辆ODD的所有变化都自动反映在技能图中,从而减少了所构建技能图中的不一致性和错误。

英文摘要:

Automated vehicles need to be aware of the capabilities they currently possess. Skill graphs are directed acylic graphs in which a vehicle's capabilities and the dependencies between these capabilities are modeled. The skills a vehicle requires depend on the behaviors the vehicle has to perform and the operational design domain (ODD) of the vehicle. Skill graphs were originally proposed for online monitoring of the current capabilities of an automated vehicle. They have also been shown to be useful during other parts of the development process, e.g. system design, system verification. Skill graph construction is an iterative, expert-based, manual process with little to no guidelines. This process is, thus, prone to errors and inconsistencies especially regarding the propagation of changes in the vehicle's intended ODD into the skill graphs. In order to circumnavigate this problem, we propose to formalize expert knowledge regarding skill graph construction into a knowledge base and automate the construction process. Thus, all changes in the vehicle's ODD are reflected in the skill graphs automatically leading to a reduction in inconsistencies and errors in the constructed skill graphs.
