• Item	the highest identified object in the process and the starting point for product-specific safety development.
• Element	anything in a system that can be identified and manipulated.
• Error	Discrepancy between a computed, observed or measured value or condition, and the true, specified or theoretically correct value or condition.
• Fault	Abnormal condition that can cause an element or an item to fail.
• Failure	Termination of an intended behaviour of an element or an item due to a fault manifestation.
• Fault Tolerance	Ability to deliver a specified functionality in the presence of one or more specified faults.
• Malfunctioning Behaviour	Failure or unintended behaviour of an item with respect to its design intent.
• Hazard	Potential source of harm (physical injury or health damage) caused by malfunctioning behaviour of the item.
• Functional Safety	Absence of unreasonable risk due to hazards caused by malfunctioning behaviour of Electrical/Electronic systems.
• Hazardous Event	combination of a vehicle-level hazard and an operational situation of the vehicle with potential to lead to an accident if not controlled by timely driver action.
• Safety Goal	is a top-level safety requirement that is assigned to a item
• Safety Requirement	includes all safety goals and all levels of requirements decomposed from the safety goals down to and including the lowest level of functional and technical safety requirements allocated to hardware and software components.
• Safety Life Cycle	identify and evaluate safety risks, establish specific safety requirements to reduce those risks to acceptable levels, and manage and track those safety requirements to delivered a final product with those requirements implemented.
HAZOP	Hazard and Operability to determining potential problems that may be uncovered by reviewing the safety of designs and revisiting existing processes
Functional Safety Concept	specifies on a vehicle level how safety goals should be achieved by getting systems to interact.
Functional safety assessment	Activity to determine if the safety system does meet the specification and actually achieve functional safety (freedom from unacceptable risk)
ISO 8800	Safety and Artificial Intelligence
Functional Safety concept	we use the derived safety goals to define functional safety requirements
• ISO 26262:	standard for functional safety of electrical and/or electronic systems road vehicles
ASIL values?	4 (ASIL A, B, C, D), determined by Severity(S0-S3), Exposure(E0-E4) and Controllability(C0-C3)
• What is ASIL	Automotive Safety Integrity Level
• Meaning of HARA	Hazard Analysis and Risk Assessment
• What is HARA process	Identify Hazardous events,, perform classification of the hazardous events, classificate the hazardous events(severity, exposure, conrolability), determine the ASIL, determine a safety goal for every hazardous events, verify, confirm
• SOTIF/ ISO 21448 meaning?	Safety of the Intended Functionality
ISO 26262 parts	10 parts, 3- Concept phase 4- Product development at the system level 5- PD at the hardware level 6- PD at the SW level 7- Production and installation planning
What is SOTIF/ ISO 21448?	It is an extension of ISO 26262 for safety with conditions like enviroment, sensing, processing of complex algorithms and HMI
SOTIF/ ISO 21448 scope	Level 1- Driver assistance Level 2- Partial automation
SOTIF/ ISO 21448 steps	-Identification and evaluation of triggering event -Functional Modification to reduce SOTIF risk -Verification & validation of SOTIF
