In recent years, trials of autonomous shuttle vehicles have been conducted worldwide. Currently, there exists no generalized process model for deployment and continuous operation of shuttles. Shuttle suppliers use their own developed procedures, making it difficult for the relevant stakeholders (e.g., public authorities) to assess the risk of potential shuttle deployment. The Digibus® Austria flagship project, among other goals, develops an approach for the virtual risk assessment of identified critical spots along proposed shuttle paths. Embedded into the deployment process, this serves as a significant body of evidence for safety assurance in shuttle deployment. Conducted simulation studies optimizing the shuttle’s trajectory for concrete maneuvers, along with derived requirements for the associated virtual environment, are part of the first noteworthy outcomes. Concretely, the developed virtual environment is integrated in the framework used for virtual validation. The framework is then used for a detailed evaluation of a right-turn maneuver, analyzing possible shuttle trajectories. Considerable differences in sensor coverage at the shuttle’s stopping point can be shown. Conclusively, by utilizing the shuttle’s restricted operational domain, the proposed virtual risk assessment is considered the first step toward a general procedure for the safety assurance of automated vehicles.

部署自主穿梭机的虚拟风险评估

近年来,自动穿梭车的试验已经在世界范围内进行。目前,还没有用于班车部署和连续运行的通用过程模型。班车供应商使用他们自己制定的程序,使相关利益相关者(例如,公共当局)难以评估潜在班车部署的风险。数字总线®除其他目标外,奥地利旗舰项目开发了一种方法,用于对拟议穿梭路径沿线已确定的关键点进行虚拟风险评估。嵌入到部署过程中,这是航天飞机部署安全保证的重要证据。进行的模拟研究优化了航天飞机的具体机动轨迹,以及相关虚拟环境的衍生要求,是第一个值得注意的成果的一部分。具体来说,开发的虚拟环境集成在用于虚拟验证的框架中。然后使用该框架对右转机动进行详细评估,分析可能的穿梭轨迹。可以显示穿梭机停靠点的传感器覆盖范围存在相当大的差异。最后,
