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.

使用传统平台构建安全的自动驾驶

现代车辆的电气架构由于与客户期望相对应的功能增长而逐年增加。然而，最新的期望，即动态驾驶任务的自动化，有望带来迄今为止所见的一些最大变化。突然之间，自动驾驶所需的功能不仅大大增加了系统的复杂性，而且还消除了通常依赖于在事后处理意外故障的人类驾驶员的后备。因此，建筑师需要比以往任何时候都更加严格，以保持与汽车行业相关的安全水平。本论文的一部分工作是与我们的工业合作伙伴 Scania CV AB 密切合作进行的，在 Vinnova FFI 资助的项目 ARCHER 中。本论文旨在提供一种在开发概念阶段进行架构设计的方法论，使用工业实践和原则，包括来自 ISO 26262 等安全标准的原则。论文的主要贡献有两个方面。第一个领域，即 A 部分，(i) 对构建自动驾驶的挑战的分析，并作为本文其余部分所采用方法的动机，即 B 部分，其中的贡献包括，(ii) 定义根据 ISO 42010 定义的功能安全观点，(iii) 从遗留组件中系统地提取信息的方法，以及 (iv) 在存在不确定性的情况下使用遗留信息和架构师提供工作产品的过程，
