The Art of Safe Updates: Strategies for Edge Device Maintenance

Feature-rich vehicles have transformed contemporary automobiles into a vast landscape of high-performance computing systems, cutting-edge devices, intricate sensors and actuators. As a consequence, the significance of functional safety has reached unprecedented levels.

What is functional safety?

Automotive functional safety involves putting in place protective measures to eliminate or reduce the severity of hazards that may arise due to failures of a vehicle. This is critical to ensuring the safety and reliability of automotive systems, protecting both the occupants of the vehicle and others on the road.

About the ISO 26262

Introduced in 2011 and revised in 2018, ISO 26262 outlines the criteria necessary to attain functional safety across the entire lifecycle of a product. This standard offers a specialized, risk-driven methodology for determining Automotive Safety Integrity Levels (ASILs), spanning from ASIL-A (demanding minimal risk reduction) to ASIL-D (mandating significant risk reduction) in the automotive domain. It covers various aspects including risk assessment, safety goals, risk reduction measures, validation and verification processes.

How eSync OTA Facilitates Functional Safety

But first, What is eSync OTA?

eSync is a bi-directional software update and data pipeline designed for managing software updates and data across diverse edge devices in a vehicle. It is built on the standardized, multi-vendor approach released as a specification from eSync Alliance, enabling a secure and efficient way to manage software updates and data gathering across different vehicle brands and models.

eSync Architecture includes -

• eSync Server — which acts as the central hub in the cloud, storing updates, managing the update delivery and data gathering processes, and communicating with vehicles.
• eSync Client — Resides within the vehicle, coordinating with the designated eSync Server for updates and with the eSync Agent(s) for device software installation and status.
• eSync Agents — comprise of small software programs embedded in individual devices, handling specific update tasks and device communication. To continue reading the article follow this link - https://excelfore.com/blog/the-art-of-safe-updates-strategies-for-edge-device-maintenance-1
