What is Functional Safety ?

Application that can cause harm (a risk): • Airbag exploding when infant is sitting in front seat

Need to assess the risk: • Infant getting injured – „not good at all“

Find a mitigation strategy, e.g. a safety function: • Detecting infant in front seat and disabling airbag

• Sensor delivers signal to • Software/Hardware controlling an • Actuator (disabler)

Functional Safety is then: • An infant in front seat is not exposed to an unacceptable (unreasonable) risk

ISO 26262 – Functional Safety for Road Vehicles


• Functional Safety for Road Vehicles • ISO 26262 is an adaption of IEC 61508 for the automotive industry

IEC 61508 – ISO 26262


Key Components of ISO 26262

• Provides an Automotive Safety Lifecycle, which covers all phases from initial

definition and planning till disassembling of the product

• Supports tailoring the necessary activities during these lifecycles phases

• Provides an automotive specific risk-based approach for determining risk classes

(Automotive Safety Integrity Level, ASILs) based on „Item“

• Uses ASILs for specifying the item‘s necessary safety requirements for achieving

an acceptable residual risk

• Provides requirements for validation and confirmation measures


Automotive Safety Integrity Level (ASIL)

• The ASIL is a key component

• The ASIL is determined at the beginning of the development process

• The intended functions of the system are analyzed with respect to possible hazards

• ASIL asks: „If a failure arises, what will happen to the driver and associated road users?“

Hazard Analysis and Risk Assessment


What is the Automotive Safety Integrity Level (ASIL)?

• Automotive specific risk-based approach for determining risk classes

• Automotive Safety Integrity Level (ASIL)


Hazard Classification

• Scored E0 – E4 (unlikely– High probability) • How often explodes an airbag while an infant is sitting in front seat ?

• Scored C0 – C3 (Controllable in general – Difficult to control or manage) • Is the infant or the driver able to control the explosion of the airbag ?

• Scored S0 – S3 (No injuries – Life- threatening injures) • How severe will the infant injured ?


Hazard Determination

Airbag Example:

E2 (low probability) + C3 (difficult to control) + S3 (life-threatening) = ASIL B


The Hazard Analysis and Risk Assessment (HARA) is used to identify and categorize the hazardsthat malfunctions in the item can trigger and to formulate the safety goals for the item so that unreasonable risks are avoided.
