COVESA has a liaison agreement with e-Sync eSync Alliance to explore common interests.

e-Sync eSync Alliance is an initiative to define Over The Air updates (OTA/SOTA) and Disgnostics.

A presentation LINK PENDING of the activities was made at the Automotive Linux Summit in Tokyo, December 2021.

Background

e-Sync eSync is interested in leveraging the use of their OTA protocol not only for software transfer (cloud to vehicle) but also data transfer (primarily vehicle to cloud). 
It was early on decided that the work within CVII to achieve an automotive industry-common data model, and use of VSS in particular, was desirable for such work.

Protocol Specification

e-Sync eSync develops and publishes OTA protocol specifications among their members.  (Contact e-Sync eSync for further details.)

Technical Prototype

The potential of a technical prototype has been discussed.  Outreach ongoing to companies that may be interested in implementing. 

Message Formats

Some of e-Sync eSync technology leverages Apache frameworks and uses AVRO encoding  and therefore we envision trying that in the technical prototype.

Components for development

• Convenience-library for data encoding.  (VSS values in, AVRO-encoded data messages out).  (C++)
• eSync has in-vehicle components that the prototype might be aligned with (e.g. modify AVRO schema to fit VSS but the code gets reused).
• Raw CAN-signals are often used.  CAN→VSS is a frequent topic, also listed in the planning/organization of CVII.
