摘要:

本文的目的是提出一个系统的分析自动驾驶汽车的传感器覆盖。由于可能的交通状况数量不受限制,因此必须在自动驾驶汽车的安全评估中选择要测试的场景。本文介绍了现象学传感器模型可以用来识别系统特定的相关场景。在自动驾驶中,主要使用以下传感器:摄像头、超声波、\radar和\lidarohne。基于文献,现象学模型已开发的四种传感器类型,其中考虑到的现象,如环境影响,传感器的属性和类型的对象被检测。这些现象学模型具有比简单的理想传感器模型显著更高的可靠性,并且比现实的物理传感器模型需要更低的计算成本,这代表了传感器覆盖的系统调查的最佳折衷。模拟结果表明,不同的系统配置之间存在显着差异,从而支持系统特定的选择自动驾驶汽车的安全评估的相关方案。

英文摘要:

The objective of this paper is to propose a systematic analysis of the sensor coverage of automated vehicles. Due to an unlimited number of possible traffic situations, a selection of scenarios to be tested must be applied in the safety assessment of automated vehicles. This paper describes how phenomenological sensor models can be used to identify system-specific relevant scenarios. In automated driving, the following sensors are predominantly used: camera, ultrasonic, \radar and \lidarohne. Based on the literature, phenomenological models have been developed for the four sensor types, which take into account phenomena such as environmental influences, sensor properties and the type of object to be detected. These phenomenological models have a significantly higher reliability than simple ideal sensor models and require lower computing costs than realistic physical sensor models, which represents an optimal compromise for systematic investigations of sensor coverage. The simulations showed significant differences between different system configurations and thus support the system-specific selection of relevant scenarios for the safety assessment of automated vehicles.
