The implementation challenges of highly automated driving systems

Functional safety has become established as a routine activity in the development of safety-related electronic systems in the automotive industry, principally through ISO 26262 which builds on existing foundations of systems engineering and reliability analysis techniques - an overview by Dr David Ward, Senior Technical Manager, Functional Safety, HORIBA MIRA Ltd

The approach to functional safety in ISO 26262 is concerned with addressing hazards that result from malfunctioning behaviour. In ISO 26262, safety requirements are developed and allocated to the item or its constituent elements, from a hazard analysis and risk assessment process including the identification of safe states. These safe states typically involve degraded functionality, and ultimately a fail-silent strategy that removes the affected function may be used.
