ISO 26262: Strengthening Functional Safety in the Evolving Automotive Landscape

As automotive technology continues to advance with innovations such as electric vehicles (EVs) and autonomous systems, ensuring safety becomes more critical than ever. To address the functional safety of automotive systems, the industry relies on ISO 26262, an international standard designed to manage the risks associated with electrical and electronic systems in vehicles.

This blog will explore the significance of ISO 26262, how it shapes the development of safety-critical automotive systems, and how iJbridge Incorporation offers specialized services to support organizations in meeting ISO 26262 requirements through training and implementation support.

Overview of ISO 26262

ISO 26262 provides a comprehensive framework for functional safety, covering all phases of a vehicle’s lifecycle from concept development to decommissioning. It is crucial for managing the safety of complex electrical and electronic (E/E) systems, which are increasingly present in modern vehicles.

The standard focuses on the following key aspects:

1. Automotive Safety Integrity Levels (ASILs): ISO 26262 introduces the concept of ASIL, which categorizes risk levels based on severity, exposure, and controllability. This categorization helps determine the level of safety measures required for each function or component.

2. Safety Lifecycle: The standard outlines a safety lifecycle that ensures all development phases are carried out with safety in mind—from hazard identification to risk assessment, system design, and testing.

3. Verification and Validation: Rigorous verification and validation processes ensure that automotive systems meet functional safety requirements and operate as intended in real-world conditions.

4. Safety Culture: Beyond technical requirements, ISO 26262 promotes a strong safety culture within organizations, emphasizing the importance of collaboration and continuous improvement in safety practices.

The Importance of ISO 26262 in Modern Automotive Systems

With the growing complexity of today’s vehicles, functional safety is critical to prevent hazardous situations arising from system malfunctions. ISO 26262 ensures that automotive systems are designed to detect, mitigate, or respond to failures safely, ensuring the overall safety of the vehicle.

Functional safety is particularly important in systems like:

• Advanced Driver Assistance Systems (ADAS): Ensuring safe performance of features like lane-keeping assistance and automatic emergency braking.

• Electric Powertrains: Managing risks related to high-voltage systems and battery management in EVs.

• Autonomous Vehicles: Ensuring reliable decision-making and fault-tolerant operations in automated driving systems.

By adopting ISO 26262, manufacturers can ensure that their products comply with international safety standards, enhancing both regulatory compliance and consumer confidence.

Implementing ISO 26262: Key Phases

ISO 26262 covers multiple phases in the development and maintenance of automotive systems:

1. Hazard Analysis and Risk Assessment (HARA): Identifies potential hazards, assesses their risk levels, and assigns appropriate ASIL ratings to prioritize safety efforts.

2. Functional Safety Concept: Establishes safety goals and outlines how the system will address identified risks.

3. System Development: Involves designing hardware and software components to meet safety goals while adhering to the guidelines set out in ISO 26262.

4. Verification and Validation: Extensive testing ensures that systems perform safely under all conditions.

5. Production and Operation: The standard extends beyond the development phase, requiring that safety considerations remain in place during production, operation, and eventual decommissioning.
