论文摘要
新兴的群众个性化生产的公路车辆，取代大规模定制，需要增加变体。问题：“在遵守标准ISO 26262：2018的同时，如何解决与变体数字相对应的功能安全开发工作？”动机这项工作。尽早将其应用于开发生命周期中时，掌握努力的杠杆最有效。启动功能安全伪像是项目定义。通过利用平台开发，可以将变体分为几个甚至单个项目定义的战略性聚类是可行的。但是，每个定义项目的功能安全开发工作只有在将所有后期基于一个单个代表性变体上的所有阶段时才能受到限制。在这项工作中，我们特别详细阐述了回答“在什么条件下可以定义代表性变体？”的问题，并伴随着“如何定义？”的概念。因此，我们评估了ISO 26262：2018，用于在代表性变体上得出先决条件。此外，我们提出了一种结构化和有效的方法，以确定给定车辆参数和框架上下文的代表性变体。对于传动系统开发中的两个易于理解的用例情况，该方法被例证了。特征方程可用于未来的传动系统功能安全开发。
The emerging mass individualization in series produced road vehicles, superseding mass customization, entails an increase in variants. The question "How may the functional safety development effort, corresponding to the variant numbers, be tackled while complying to the standard ISO 26262:2018?" motives this work. The lever on containing the effort is most effective when applied in the development life-cycle as early as possible. The initiating functional safety artifact is the item definition. Strategic clustering of variants into a few or even a single item-definition(s) is feasible by exploiting platform development. Yet, the functional safety development effort for each defined item may only be limited when basing all subsequent phases on one single representative variant. In this work we particularly elaborate on answering the question "Under what conditions can a representative variant be defined?", accompanied by the notion of "How is it defined?". Therefore, we assess the ISO 26262:2018 for deriving prerequisites on a representative variant. Furthermore, we propose a structured and efficient method to determine representative variants given vehicle parameters and a framing context. The method is exemplified for two easily comprehensible use-case situations in drivetrain development. The characteristic equations may be used for future drivetrain functional safety development.
