Safety Critical

In the last decade, modern vehicles have become very complex, being equipped with embedded electronic systems which include more than a thousand of electronic control units (ECUs). Therefore, it is mandatory to analyze the potential risk of automotive systems failure because it could have a significant impact on humans’ safety. This paper proposes a novel, functional safety concept at the power management level of a system basis chip (SBC), from the development phase to system design. In the presented case, the safety-critical application is represented by a powertrain transmission electronic control unit. A step-by-step design guideline procedure is presented, having as a focus the cost, safety, and performance to obtain a robust, cost-efficient, safe, and reliable design. To prove compliance with the ISO 26262 standard, quantitative worst-case evaluations of the hardware have been done. The assessment results qualify the proposed design with automotive safety integrity levels (ASIL, up to ASIL-D). The main contribution of this paper is to demonstrate how to apply the functional safety concept to a real, safety-critical system by following the proposed design methodology.

AbstractStructuring the early design phase of automotive systems is an important part of efficient and successful development processes. Today, safety considerations (e.g., the safety life cycle of ISO 26262) significantly affect the course of development. Preliminary designs are expressed in functional system architectures, which are required to form safety concepts. Thus, mapping tasks and work products to a reference process during early design stages is an important part of structuring the system development. This contribution describes the systematic creation and notation of the functional safety concept within the concept phase of development of an unmanned protective vehicle within the research project aFAS. Different stages of preliminary design and dependencies between them are displayed by the work products created and used. The full set of functional safety requirements and an excerpt of the safety argument structure of the SAE level 4 application are presented.
