Connected car OTA spec enhances data gathering, cybersecurity
The eSync Alliance, a multi-company initiative for over-the-air (OTA) updates and diagnostics for connected cars, has announced the release of v2.0 of the eSync specification.

Based on a server/client/agent architecture, the eSync software platform provides a secure data path between the cloud and any number of electronic end devices located inside a vehicle, enabling OTA software updates that can save time and money. It can work across multiple operating systems and networks/buses to reach any ECU or smart sensor in the car, says the organization.

The v1.0 specifications of the eSync Alliance, released in April of 2019, focused on OTA installation of software into edge devices in the complex networks of modern vehicles. The new release, says the organization, expands on data gathering while further extending the cybersecurity specifications for OTA software update capabilities of eSync, with full bi-directional communications in a single pipeline.

"eSync now reaches well over 30 million devices in more than 1 million vehicles," says Mike Gardner, Executive Director at the eSync Alliance, "and we already have automakers that are deploying eSync in their third, fourth and even fifth vehicle models. This demonstrates that it is a practical, executable specification with tangible, quantifiable benefits."

The new v2.0 expands the specifications and guidelines for diagnostic data gathering over the air, providing structures for short message data such as diagnostic trouble codes, bulk data transfer for data collected from numerous devices over time, and streaming data from sensors. Also included in the v2.0 specifications are guidelines for meeting regulatory requirements and standards defined by UNECE, NIST, NHTSA and ITU addressing cybersecurity and data privacy.

The eSync Alliance is an initiative established to standardize OTA updating and data gathering for the connected car through a global network of co-operating companies including such major automotive suppliers such as Alps Alpine, Faurecia, Hella, Molex and ZF. Alliance members benefit from a simplified development environment, enabled by the standardization of architecture, functional behavior and APIs, making deployment faster and easier, and providing end-to-end security for automotive OEMs and suppliers. Membership is open to all companies, including OEMs, Tier-1s, software and hardware vendors, and cloud service providers.
