使用传统平台构建安全的自动驾驶
Architecting Safe Automated Driving with Legacy Platforms
摘要：
现代汽车的电气架构复杂性逐年增长，这是由于功能增长与客户期望相对应。然而，最新的期望，动态驾驶任务的自动化，有望带来迄今为止最大的变化。一举，不仅自动驾驶所需的功能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。本论文的部分工作是在Vinova FFI资助的项目ARCHER中与我们的工业合作伙伴Scania CV AB密切合作进行的。本论文的目的是提供一种方法，在开发的概念阶段，使用工业实践和原则，包括那些从安全标准，如ISO 26262的架构。本文的主要贡献在于两个方面。第一个领域，即A部分的贡献，（i）对架构自动驾驶的挑战进行分析，并作为本论文其余部分所采用方法的动机，即B部分，其中贡献包括，（ii）根据ISO 42010的定义功能安全的观点，（iii）从遗留组件中系统地提取信息的方法;（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，即ISO 26262所要求的初步架构假设（PAA）。B部分的贡献共同构成了构建PAA的方法。<read full abstract in pdf>
英文摘要：
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>
