In the past the causes of unsafe behaviour were limited to malfunctioning behaviour of electrical or electronic systems due to random or systematic faults and were addressed by the application of the international standard ISO 26262. The introduction of automotive systems with greater authority and autonomy (for example, highly automated driving systems) changes this as unsafe behaviour may also now be caused by incorrect or incomplete specification of the intended functionality – for which the term ‘SOTIF’ (Safety Of The Intended Functionality) has been coined within the industry.
HORIBA MIRA has been actively involved in the authorship of the newly released Publicly Available Specification ISO/PAS 21448, Road Vehicles – Safety of the Intended Functionality. MIRA has developed its own in-house SOTIF process which aligns with the requirements of the PAS but extends its principles to apply to higher levels of autonomy. MIRA’s experience and expertise in this area is distilled into this course to enable delegates to perform their own SOTIF analyses
Prior experience with applying functional safety according to ISO 26262 would be highly beneficial.
- Describe the purpose and role of SOTIF
- Identify SOTIF hazards
- Apply techniques for reducing risk associated with these hazards
- Understand how to determine the acceptance of residual risk
