Interview Questions On Functional Safety

20. What is implied by functional safety?

Ans. The word functional safety (FuSa) is described by ISO 26262 as the lack of unacceptable risk due to risks caused by malfunctioning conduct of E/E (electrical and electronic) systems. Associated with hardware elements, the objectives are to stop frequent design defeats and witness and control unexpected hardware faults.

19. What will be the functional safety standards for automotive cars?

Ans. ISO 26262 is a global standard for functional safety in the automotive enterprise. The standard involves electrical and electronic systems consisting of hardware and software elements in automobiles.

18. What are functional safety requirements?

Ans. The functional safety idea includes the functional safety needs (requirements) (FSRs) that are derived from the safety objectives and explain the steps that are to be executed on a functional level to control violation of the safety objectives.

17. What is a functional safety concept in ISO 26262?

Ans. A “functional safety concept” sets on an automobile level how safety objectives should be completed by reaching systems to interact. Item description. The term “item” conveys the subject of development, your outcome. These are 1 or more interacting electrical or electronic systems that execute the desired function.

16. Why is functional safety essential?

Ans. The systems protected under functional safety are developed to automatically control risky failures or to manage them when they happen. It allows us to create a system that can perform specific functions perfectly, even under non-intended service(or occasionally even abuse).

15. Who is accountable for functional safety?

Ans. According to ISO 26262, the accountability for completing functional safety lies with the project supervisor/manager, not the safety supervisor/manager.

14. What is the difference between safety and functional safety?

Ans. A thermal sensor in a system that drives the design to cut out if it overheats is a functional safety standard. Insulation to defend the system against high temperatures is a safety standard but not a functional safety standard.

13. What is functional safety assessment?

Ans. The Functional Safety Assessment (FSA) is an experiment to decide if the safety function under study reaches the needed level of functional safety to sustain a decision to either improve to the next phase of the lifecycle or stay in the same phase until all required steps are in place.

12. What is ASIL ABCD?

Ans. ASIL which stands for Automotive safety integrity classes is a risk category scheme prescribed under ISO 26262 (functional safety for road automobiles). Generally, there are 4 types. ASIL A, B, C, D. D dictates the most increased integrity and A is the lower.

11. What is functional ISO?

Ans. ISO 26262, titled “Road vehicles — functional safety”, is a functional safety standard utilized in the automotive industry, and ASIL is a critical component to defining safety needs for software development. Yielding this standard is essential for automotive product development.

10. What are safety goals in functional safety?

Ans. According to ISO 26262 standard, Safety Objectives are the top-level safety needs for each item. These objectives go on to develop the functional safety requirements, required to bypass any unreasonable risk for each of the dangerous events.

09. What is ISO 26262 ASIL D?

Ans. ASIL-D is an automotive risk category that is an aspect of a larger ISO standard – ISO 26262 – which examines the functional safety needs for all of the various electrical and electronic systems in a vehicle.

08. What is FSC and TSC?

Ans. The FSC includes a set of functional safety requirements (FSR) that jointly imply all the SGs. After this tracks the technical safety concept (TSC), in which a group of technical safety requirements (TSR) shall be revealed and how they imply the FSC.

07. What does ASIL QM mean?

Ans. Therefore, it is categorized as ASIL A, or quality management (QM). QM directs to the standard’s consideration that it is below ASIL A in which there is no safety relevancy, and only standard QM processes are needed to fulfill any applicable requirements.

06. How do you become a functional safety supervisor?

Ans. A Bachelor’s and/or Master’s degree in Software Engineering, Electrical, or related. 5 years of knowledge in the domain of Functional Safety within a high-tech circumstance. At least 2 years of background as a Functional Safety Manager. Understanding the application of safety standards ISO26262 and automotive safety estimation.

05. How many parts are there in ISO 26262?

Ans. ISO 26262:2018 consists of 12 parts, ten normative parts (parts 1 to 9 and 12), and two guidelines (parts 10 and 11): Vocabulary. Management of functional safety.

04. How is ASIL calculated?

Ans. The ASIL is demonstrated by conducting a risk examination of potential risk by looking at the Severity, Orientation, and Controllability of the vehicle operating strategy. The safety objective for that hazard in turn holds the ASIL requirements. There are four ASILs specified by the standard: ASIL A, ASIL B, ASIL C, and ASIL D.

03. What is the difference between Aspice and ISO 26262?

Ans. ISO 26262 shields functional safety standards for automobiles. It includes safety analysis approaches that account for unexpected and systematic errors in electrical and electronic systems and is largely adopted worldwide. ASPICE is the present standard for software best approaches in the automotive enterprise.

02. What is the difference between IEC 61508 and ISO 26262?

Ans. ISO 26262 utilizes a very thorough Hazard Analysis and Risk Assessment (HARA) that is created into the standard. Yet, IEC 61508 permits more flexibility for their Hazard and Risk Analysis in which different techniques can be utilized to estimate hazards, including approaches common in the ISO 12100 standard.

01. Where can I download ISO 26262?

Ans. This standard contains general subjects for initiating product outcomes at the system level, specifications for technical protection, the technical safety concept, system architectural structure, object integration, and testing, and safety assurance. One can download ISO 26262-4:2018 from the ANSI Webstore.
