The Crucial Role of ISO 26262 in Shaping Safety Standards for EVs

Blog

Over the past few years, the EV market has witnessed rapid growth, which is expected to continue over the next decade. In 2022, the number of EVs on the road exceeded 26 million, a 60% increase from 2021 and more than five times the amount from 2018[1]. As the automotive industry constantly develops and new technologies emerge, the need for safety procedures has become increasingly crucial to ensure the reliability and durability of EVs, and most importantly, drivers’ safety. Safety standard, ISO 26262, plays a key role in this pursuit of safety while significantly impacting EVs and the automotive industry.

Navigating the Road to Automotive Safety

ISO 26262, also known as “Road vehicles — functional safety, is an international standard for the functional safety development process of electrical and electronic systems in road vehicles. Adopted in 2011, it defines guidelines to minimize accident risks and ensure automotive components meet safety and reliability requirements. ISO 26262 is a crucial framework for manufacturers, suppliers, and developers alike, which defines a comprehensive approach and procedures to safety management throughout the lifecycle of an automotive component.

Guiding Development with ASIL and Safety Goals

Within ISO 26262 lies the risk classification system, Automotive Safety Integrity Level (ASIL), which performs a risk analysis of potential hazards based on the severity and probability of potential failures. Ranging from A to D, ASIL D represents the highest potential risk to human safety, while ASIL A represents the lowest risk level. This classification system determines the levels of safety measures required, guiding the design and implementation throughout the development process. As such, ASIL plays a crucial role in automotive safety, setting the direction for necessary measures in EV development.

Furthermore, safety goals derived from the ASIL risk classification system are specific and measurable targets that ensure system or product safety. Tailored to OEMs’ requirements, these high-level safety requirements influence design decisions, guide safety procedures, and are crucial to achieving desired safety levels throughout the development lifecycle.
