The process of hazard analysis and risk assessment (H&R or HARA) is well-established in standards and methods for functional safety, such as the automotive functional safety standard ISO 26262. Considering the parallel discipline of cyber security, it is necessary to establish an analogous process of threat analysis and risk assessment (T&R) in ord...

To achieve the aims of reducing energy consumption and CO2 emissions, Fully Electric Vehicles (FEVs) need to reach a significant market share. However, the advent of FEVs in mass production presents new challenges to automotive manufacturers due to the relative immaturity of the new building blocks, which may impact on the FEV's safety and reliabil...

ISO 26262 is considered to represent the “state of the art” for the development of vehicle electronic systems, specifically of safety relevant systems in passenger vehicles. ISO 26262 is an automotive interpretation of the generic functional safety standard IEC 61508 [1]. Premium segment passenger vehicles are equipped with a vast number of control...

One of the main aims of the EC project HEMIS is to design a prognostic health monitoring system for electrical powertrain components in order to enhance the safety and maintainability of electric vehicles. This paper outlines some of the preliminary work carried out in the areas of safety and failure analysis, based on a generic architecture that a...

Active safety systems are perceived as enablers for reducing road fatalities significantly, as they can improve the vehicle performance in critical situations where the driver may not otherwise be able to react in time. These systems are showcasing higher degrees of automation, which make them ideal candidates for migration to full autonomy. This p...

This paper presents a safety argument using GSN to support product development at the “concept phase”, following ISO 26262-3, with emphasis on the application of the standard to complex “items” that integrate multiple functions.

With the growing complexity of, and reliance on, safety-related electrical/electronic (E/E) systems in the automotive sector, the development of an explicit safety case is highly recommended to provide assurance to the different stakeholders interested in automotive functional safety. The production of a safety case is explicitly mandated by the dr...

The civil aviation industry has expanded considerably in aircraft systems in the 100 years of its life. Although there are major developments in all aspects of flight, the fastest growing trend is for More electric aircraft (MEA) and low emissions; consequently, the complexity of electrical and electronic systems is increasing. It is therefore high...

The inherent nature of military vetronic systems, whose core constituents are a combination of soft and hard real-time, distributed, and in most cases embedded systems with mixed criticality; inevitably poses a challenge as how to deal with multidimensional complexity. Such complexity is not only the result of the actual technologies used but the s...
