Maximize Your Product's Potential

Best-in-Class Security

The eSync OTA data pipeline incorporates an industry best practices “zero trust” model to ensure secure delivery and verification of software updates and parameter files. Links are mutually authenticated both to the cloud and within the vehicle, providing a layered defense. Contents are encrypted both in transit and at rest. And payloads are verified to the root of trust before and after installation, to bit-level accuracy, to ensure that no contents are ever corrupted.

When you want it
Flexibility and Scalability

The eSync OTA pipeline uses distributed agents to perform the bulk of the update tasks for any particular edge device. Unique device requirements are encapsulated into the agent for that device. Additional devices are added by providing additional agents. eSync is proven to update all popular automotive Operating Systems, and is deployed for vehicles where it updates only one device, or more than 65 different edge devices.

Future-proofing & Innovation

Fix shortcomings, comply with changing regulations, enhance functionality and efficiency, and add new features. Use your connectivity to ensure that the vehicle, and the devices in the vehicle, can adapt to evolving market demands throughout the product life cycle. eSync OTA future-proofs your product, preparing it for new features, technical capabilities, and requirements.

Time and Cost Savings

OTA from Excelfore saves time and cost in development and throughout the vehicle life cycle.  Development is quicker due to the standard structured approach of the eSync pipeline, with OEM integration projects completed in as little as 4 months. In the field, full vehicle OTA reduces manual updates and recalls, saving channel costs and customer time.

Key Features

Sharpen Your Competitive Edge

Full Vehicle OTA
Full Vehicle OTA

eSync OTA from Excelfore is a proven solution for updating all the programmable devices in the vehicle. Updating a high-performance computing platform running the latest autonomous driving stack, an airbag controller running classic AUTOSAR, or a small seat positioning and heating controller with an open-source RTOS environment, eSync gives you a consistent approach to updating the whole vehicle.

Fault Tolerance
Fault Tolerance

The eSync pipeline is highly tolerant to interruptions and transmission errors. Interrupted streams do not need to re-start, but can continue from the latest checkpoint. When installations fail, retries and rollbacks happen automatically, including the rollback of interdependent devices to ensure concurrent generations of software.

Advanced Security
Advanced Security

eSync provides best-in-class cybersecurity, with mutual authentication, layered defenses, and payload encryption at rest and in transit. Data integrity checking ensures bit-level verification of every payload to the root-of-trust both before and after installation into the ECU.

Telematics Integration
Adaptive Delta Compression

Excelfore’s patented Adaptive Delta Compression technology reduces payload size by as much as 95%, reducing operating costs while providing the tools to prevent excessive vehicle downtimes due to in-vehicle processing.

Amazon CloudFront
Bi-Directional Pipeline

eSync is a bi-directional data pipeline. It not only pushes updates to the vehicle for installation, but also pulls data from the vehicle, providing updates to OEM vehicle databases and providing the foundation for advanced eDatX data aggregation.

PD Framework

eSync has been deployed in production programs to update one device, or more than 65 devices.  It scales to update as many devices as you want to update.

Adaptive Compression
Flexible In-Vehicle Deployment

eSync uses a standardized set of embedded components which span all popular automotive operating systems, network and bus interfaces, and EE architectures.

Fault Tolerance
Flexible Cloud Integration

Leverage the microservices-based architecture of eSync to enable seamless integration with OEM databases and Cloud services.

Over-The-Air Updates
Flexible Operation

The dynamic “policy” construct within eSync allows the OTA administrator to change the behavior of the update pipeline without re-coding any of the embedded or cloud components.

eSync is an advanced over-the-air technology designed for software enhancement and data extraction from connected vehicles. It offers a secure data conduit, allowing access to numerous electronic devices irrespective of their vendor, network, bus type, or operating system.

Vehicle manufacturers can retrieve data from ECUs in formats like concise message data, voluminous diagnostic data, or continuous streams (sourced from devices like cameras or LiDARs). Moreover, eSync offers the flexibility of dispatching diagnostic scripts from its server to the endpoint apparatus, granting a command interface for initiating and ceasing the collection of specialized ECU data, which is pivotal for remote troubleshooting.

At its core, eSync uses Agents strategically distributed across the in-car network, handling a significant share of update functions. These Agents, embedded within edge apparatuses or stationed near them, manage simultaneous updates across several devices, curtailing vehicle inactivity periods. Customized to the apparatuses they cater to, these Agents consolidate devices of varied characteristics into a singular data channel.

eSync is not limited to a singular operating system. Its technology guidelines clarify the design, operational dynamics, and interfaces of the Server, Client, and Agents, which can be incorporated into any OS. So far, eSync software modules have been integrated with platforms like Android, Linux, QNX, AUTOSAR, Integrity, and other niche real-time OSs such as Erika and FreeRTOS.

What sets eSync technology apart is its structured methodology, relying on distributed software agents equipped with well-defined, publicly accessible APIs. This layout promotes collaborative efforts from multiple entities, fostering the creation of a uniform bidirectional OTA data conduit. The eSync Alliance lays out comprehensive guidelines, enabling member entities to construct their eSync-compatible data channel segment.
