The specifications now presented provide a standardized mechanism for remotely installing updates and collecting real-time data from all electronic devices in the networked vehicle. The set of rules consists of nearly 400 pages, divided into Architecture, Requirements, Interfaces and Security sections. The specifications allow Tier 1 suppliers to provide "prepared" products for OTA that can be easily integrated into the entire vehicle's OTA platform. Several vendors can now offer eSync-compliant OTA server solutions, or alternatively automotive manufacturers can develop or customize their own proprietary cloud solutions to become eSync-compliant.
The eSync platform helps avoid costly and unpleasant vehicle recalls that plague the automotive industry. In 2016, the cost of software recalls was estimated at $3 billion in the U.S. alone. The new specifications also offer automotive manufacturers the opportunity to offer ongoing functional improvements for vehicles in the field.
The system uses a unique server-client-agent architecture for secure bidirectional transactions between the cloud and any number of electronic devices in a vehicle. It can deliver and update software and firmware over-the-air (OTA) and capture real-time operational data from any device in the vehicle.
Membership in the eSync Alliance comprises three levels: Charter, Promoter and User. All members have access to the specifications as well as the opportunity to participate in user days and demonstrate the conformity of their products.
