论文摘要
现代车辆具有电气体系结构，其复杂性年复一年，这是由于与客户期望相对应的增长。然而，最新的期望是动态驾驶任务的自动化，有望带来迄今为止看到的一些最大变化。一口气，自动驾驶不仅需要功能大大提高系统的复杂性，而且还消除了人类驾驶员的后备，这些人通常依靠在事实后处理意外的故障。因此，建筑师的需求比以往任何时候都更加严格，以维持与汽车行业相关的安全水平。本论文的一部分的工作是与我们的工业合作伙伴Scania CV AB密切合作的。该论文旨在使用工业实践和原则（包括根据安全标准，例如ISO 26262）提供一种在开发概念阶段进行架构的方法。该论文的主要贡献在两个领域。 The first area i.e. Part A contributes, (i) an analysis of the challenges of architecting automated driving, and serves as a motivation for the approach taken in the rest of this thesis, i.e. Part B where the contributions include, (ii) a definition of a viewpoint for functional safety according to the definitions of ISO 42010, (iii) a method to systematically extract information from legacy components and (iv) a process to use legacy information and architect in提供工作产品的不确定性存在，即ISO 26262要求的初步体系结构假设（PAA）。B部分的贡献构成了构建PAA的方法。 <在PDF中阅读完整摘要>
Modern vehicles have electrical architectures whose complexity grows year after year due to feature growth corresponding to customer expectations. The latest of the expectations, automation of the dynamic driving task however, is poised to bring about some of the largest changes seen so far. In one fell swoop, not only does required functionality for automated driving drastically increase the system complexity, it also removes the fall-back of the human driver who is usually relied upon to handle unanticipated failures after the fact. The need to architect thus requires a greater rigour than ever before, to maintain the level of safety that has been associated with the automotive industry. The work that is part of this thesis has been conducted, in close collaboration with our industrial partner Scania CV AB, within the Vinnova FFI funded project ARCHER. This thesis aims to provide a methodology for architecting during the concept phase of development, using industrial practices and principles including those from safety standards such as ISO 26262. The main contributions of the thesis are in two areas. The first area i.e. Part A contributes, (i) an analysis of the challenges of architecting automated driving, and serves as a motivation for the approach taken in the rest of this thesis, i.e. Part B where the contributions include, (ii) a definition of a viewpoint for functional safety according to the definitions of ISO 42010, (iii) a method to systematically extract information from legacy components and (iv) a process to use legacy information and architect in the presence of uncertainty to provide a work product, the Preliminary Architectural Assumptions (PAA), as required by ISO 26262. The contributions of Part B together comprise a methodology to architect the PAA. <read full abstract in pdf>
