The international standard for automotive functional safety, aimed at reducing risks from failures of electrical and electronic systems to an acceptable level. It adapts IEC 61508 to road vehicles and covers the whole lifecycle from concept through development and production to decommissioning.
Japanese name: ISO 26262
ISO 26262 appears in 14 practice questions across 2 topics, including Automotive Semiconductors and Functional Safety, Reliability.
Answer: A. A standard for reducing hazards caused by failures of electrical and electronic systems in series-production road vehicles, adapted for automotive use from IEC 61508
ISO 26262 is a functional safety standard for reducing to an acceptable level the risk that a vehicle behaves hazardously due to failures of electrical and electronic systems. It adapts IEC 61508, the basic functional safety standard for electrical/electronic/programmable electronic systems, to automotive use and covers the entire lifecycle from concept through development, production and decommissioning. Crash safety concerns body and airbag performance and is addressed by other requirements. The automotive standard for quality management is IATF 16949.
Answer: A. Severity (S), exposure (E), controllability (C)
The ASIL is determined for each hazardous event by evaluating three factors: severity S, representing how serious the injuries are; exposure E, representing the frequency or duration of exposure to driving situations in which the hazard can occur; and controllability C, representing how likely the driver or others are to avoid the hazard. For example, sudden loss of braking at high speed has high severity and is hard to avoid, so it receives a high ASIL. Failure rate, diagnostic coverage and FTTI are quantities used after the ASIL is determined, to evaluate whether a design meets its requirements.
ISO 26262 is a functional safety standard for reducing to an acceptable level the risk that a vehicle behaves hazardously due to failures of electrical and electronic systems.
Which correctly describes the functional safety standard IS…It does not mean a component exempt from ISO 26262.
Which correctly describes SEooC (Safety Element out of Cont…ISO 26262 is a functional safety standard for preventing hazards caused by random hardware failures and systematic failures, evaluating risk through HARA.
Which correctly describes the difference between the automo…Failure due to component degradation is a random hardware failure and a software error is a systematic failure; both are handled by ISO 26262.
Which of the following problems is addressed mainly by SOTI…ISO 26262 defines functional safety as the absence of unreasonable risk due to hazards caused by malfunctioning behavior of E/E systems.
