About Functional Safety
Safety practices are becoming more regulated as industries adopt a standardized set of practices for designing and testing products. ISO 26262 addresses the needs for an automotive-specific international standard that focuses on safety critical components. ISO 26262 is a derivative of IEC 61508, the generic functional safety standard for electrical and electronic (E/E) systems.
Increasing complexity throughout the automotive industry is resulting in increased efforts to provide safety-compliant systems. For example, modern automobiles use by-wire systems such as throttle-by-wire. This is when the driver pushes on the accelerator and a sensor in the pedal sends a signal to an electronic control unit. This control unit analyzes several factors such as engine speed, vehicle speed, and pedal position. It then relays a command to the throttle body.
It is a challenge of the automotive industry to test and validate systems like throttle-by-wire. The goal of ISO 26262 is to provide a unifying safety standard for all automotive E/E systems.
Key Components of ISO 26262
- Provides an automotive safety lifecycle (management, development, production, operation, service, decommissioning) and supports tailoring the necessary activities during these lifecycle phases
- Provides an automotive specific risk-based approach for determining risk classes (Automotive Safety Integrity Levels, ASILs)
- Uses ASILs for specifying the item’s necessary safety requirements for achieving an acceptable residual risk
- Provides requirements for validation and confirmation measures to ensure a sufficient and acceptable level of safety being achieved
No electronic product is without embedded systems in the market and massive progress is being made in the automotive sector globally.
- Embedded systems industry will reach $360 billion by the end of 2020.
- Jobs in the embedded industry will reach to 12 Lakhs by 2020.
- Companies like TCS, Wipro, L&T, TATA, Elexsi, Infosys, Zensar, Tech Mahindra, Volvo, Airbus, Toshiba are investing heavily in their embedded systems operations in India.
- Mobile manufacturers like Foxconn are setting up their plant in India.
- Safety Plan Creation and Functional Safety Management at the organizational level
- Concept Phase Management
- System Safety Architecture Definition
- Safety Analysis and Design
- Coding and Design Implementation
- Safety Verification and Validation Support
- ISO 26262 Functional Safety Standard
