The International Organisation for Standardisation, ISO has updated its standards rules for the electronics in vehicles.

The organisation says that the purpose of the ISO 26262 series of standards is to mitigate those risks by providing guidelines and requirements for the functional safety of electrical and electronic systems.

Published in 12 individual parts, ISO 26262, Road vehicles – Functional safety, has just been updated to cope with  new technologies, and to be relevant to even more applications.  Changes include the addition of specific requirements for semi-conductors as well as new requirements for motorcycles.

ISO says functional safety features form an integral part of each automotive product’s development phase, from specification and design to implementation, integration, verification, validation, and ultimately production release. ISO 26262 defines functional safety for all automotive electronic and electrical safety-related systems, covering their entire life cycle including the development, production, operation, service and decommissioning.

The series also details an automotive-specific, risk-based approach for determining risk classes, known as Automotive Safety Integrity Levels (ASILs). ASILs are established by performing a risk analysis of potential hazards based on three variables: severity, probability of exposure and controllability by the driver.
