| ISO26262 (Road vehicles - Functional Safety) | ISO/IEC 15504 Automotive SPICE | |
|---|---|---|
| Definition | The ISO 26262 series of standards is the adaptation of IEC 61508 series of standards to address the sector specific needs of electrical and/or electronic (E/E) systems within road vehicles. This adaptation applies to all activities during the safety lifecycle of safety-related systems comprised of electrical, electronic and software components. | The Automotive SPICE process assessment model (PAM) is ntended for use when performing conformant assessments of the process capability on the development of embedded automotive systems. It was developed in accordance with the requirements of ISO/IEC 33004. |
| ISO PAS/21448 (Road vehicles – Safety of the Intended functionality) | Model Based System Engineering Service | |
| Definition | The absence of unreasonable risk due to hazards resulting from functional insufficiencies of the intended functionality or by reasonably foreseeable misuse by persons is referred to as the Safety Of The Intended Functionality (SOTIF). This document provides guidance on the applicable design, verification and validation measures needed to achieve the SOTIF. This document does not apply to faults covered by the ISO 26262 series or to hazards directly caused by the system technology (e.g. eye damage from a laser sensor). | Systems engineering is a multidisciplinary approach for developing solutions to complex engineering problems. The continuing increase in system complexity is demanding more rigorous and formalized systems engineering practices. In response to this demand, along with advancements in computer technology, the practice of systems engineering is undergoing a fundamental transition from a document-based approach to a model-based approach. In a model-based approach, the emphasis shifts from producing and controlling documentation about the system, to producing and controlling a coherent model of the system. Model-based systems engineering (MBSE) can help to manage complexity, while at the same time improve design quality and cycle time, improve communications among a diverse development team, and facilitate knowledge capture and design evolution. |
