The eSync Alliance – a global automotive initiative established to build a secure, multi-vendor platform for end-to-end over-the-air updating and data services for the connected car – has updated its standard-setting specification for over-the-air (OTA) data exchange.
eSync is a bi-directional OTA pipeline standard for the automotive industry, designed to enable auto makers to deliver remote vehicle updates that can reach every area of the vehicle. Manufacturers can also receive diagnostic data back from a vehicle through the same data pipeline.
At eSync’s core is the eSync Alliance, a non-profit trade association that encourages collaboration between OEMs and Tier 1 suppliers to define and advance a standardized multi-company approach for automotive OTA. The latest, Version 2.2 eSync specification focuses on interoperability, enabling greater collaboration among auto makers and suppliers and accelerating the development of software-defined vehicles (SDVs).
Version 2.2 draws on the accumulated experiences of alliance members in implementing numerous OTA programs to clarify the specification.
Based on the three-level Server-Client-Agent architecture of eSync, the new specification ensures that devices with agents from numerous sources can quickly be integrated into the common OTA data pipeline, alliance members state.
eSync Alliance’s Compliance Working Group has also launched an eSync Agent Validation Tool, designed to provide users with the capability to test their eSync implementations. The web-based interface enables full verification of the OTA processes of an eSync agent, the alliance says.
For Tier 1 suppliers, a fully interoperable, standardized approach to OTA can allow businesses to supply an OTA-ready solutions to auto makers that can be integrated into the platform architecture.
Mike Gardner, executive director of the eSync Alliance, said, “With Version 2.2 of our specification, we’re standardizing the standard. Users of eSync technology can rest assured that, by implementing the latest edition of the specification and making use of the Agent Validation Tool, they’re able to create interoperable solutions that will shape the SDVs of the future.
“Version 2.2 is about practical improvements that make eSync technology a consistent solution for OEMs and Tier 1s, and is the step change that will facilitate significant growth in the years to come.”
