Analysis of ISO 26262 Compliant Techniques for the Automotive Domain

The ISO 26262 standard denes functional safety for automotive E/E systems. Since the publication of the rst edition of this standard in 2011, many dierent safety techniques complying to the ISO 26262 have been developed. However, it is not clear which parts and (sub-) phases of the standard are targeted by these techniques and which objectives of the standard are particularly addressed. Therefore, we carried out a gap analysis to identify gaps between the safety standard objectives of the part 3 till 7 and the existing techniques. In this paper the results of the gap analysis are presented such as we identied that there is a lack of mature tool support for the ASIL sub-phase and a need for a common platform for the entire product development cycle

Tailoring complexity metrics for simulink models

The size and complexity of Simulink models is constantly increasing, just as the systems which they represent. Therefore, it is beneficial to control them already at the design phase. In this paper we establish a set of complexity metrics for Simulink models to capture diverse aspects of complexity by proposing new and redefining existing metrics. To evaluate the applicability of our metrics, we compare them with the closed-source metric proposed by Mathworks. Moreover, through a case study from the automotive domain, we relate such metrics to quality attributes as determined by domain experts, and correlate them to known faults. Preliminary assessment suggests that complexity is closely related to analysability, understandability, and testability

Automotive architecture description and its quality

This research is part of the Hybrid Innovations for Trucks (HIT), an ongoing multi-disciplinary project with the objectives of CO$_2$ emission reduction and fuel saving for long haul vehicles. Achieving this goal necessitates definition of a proper architecture and quality techniques to enable the development of a new and more efficient control software. Therefore, this research covers automotive architecture description language and quality of automotive software.
