As software-intensive systems become more pervasive, more and more safety-critical systems are being developed and deployed. Yet when most people think about safety requirements, they think of safety-critical functional requirements, which are requirements that have critical safety ramifications if not correctly implemented. However, there are actually four major...

Product line engineering is applied in many engineering domains. It is used to save development time by reusing system components in an organized way. While developing safety critical systems this approach is complicated by the fact, that safety concepts on higher abstraction levels need to be fulfilled by the different variants of the system. This typical leads to the creation of individual sa...

Preliminary work on the development of measures appropriate for the safety domain is reported. Measures are expressed in the style of the Practical Software and Systems Measurement (PSM) approach, a programme sponsored by the US DoD. Proposed measures are integrated with the PSM measurement framework. Reported work has been informed by discussions within the PSM community and by concurrent work...

The ISO 26262 standard is increasingly being used to develop safety-related ECU software. At the beginning of a standard-conformant development process, the developer performs a hazard analysis and risk assessment of the system under development. The developer establishes safety goals and assigns each of them a specific Automotive Safety Integrity Level (ASIL), ranging from A to D, based on the...

The automotive industry has started its transformation towards Software-Defined Vehicles. This is driven by the rise of number vehicle features, high complexity these features and their constraining availability requirements which affect all players (Original Equipment Manufacturers, Tier1 Tier2) sector. In context this transformation, our target, from functional safety point view, to, inter al...

The increasing use of lithium batteries and the necessary integration battery management systems (BMS) has led international standards to demand functional safety in electromobility applications, with a special focus on electric vehicles. This work covers complete design an enhanced automotive BMS from concept phase verification activities. Firstly, detailed analysis intrinsic hazards lithium-b...

Today’s industrial product lines in the automotive and construction equipment domain face the challenge to show functional safety standard compliance and argue for the absence of failures for all derived product variants. The product line approaches are not sufficient to support practitioners to trace safety-related characteristics through development. We aim to provide aid in creating a safety...
