Wind River advances automotive OTA technology with differential system

Wind River announced enhancements to Wind River Edge Sync, including differential system technology that enables the smallest differential update when conducting over-the-air updates. The ability to keep updates minimal reduces distribution time and cost, update transmission time, and memory required on automotive electronic control units. Wind River’s latest Edge Sync technology has been supplied to major automakers, most recently for Ford.

Efficient differential updates are an important functionality necessary for a successful, production-grade automotive OTA solution. The management of software over the course of a vehicle’s lifetime has become increasingly important to both maintaining system value and as a means of addressing security, and OTA update technology is a key element of this. Among its many features, Edge Sync differential system technology includes patch streaming, patching in place, A/B updates, pause and resume and a reduced memory footprint of software client.

Edge Sync is Wind River’s highly modular, end-to-end OTA update and software lifecycle management solution that allows for rapid, safe, and secure updates to software and firmware. Edge Sync meshes seamlessly with automakers’ proprietary systems or with third party data solutions enabling car companies to efficiently manage and maintain automotive software for the entire life of the car and to continuously improve the value of the car and experiences with customers on a long- term basis.

Beyond OTA and software lifecycle management, Wind River’s diverse automotive portfolio also includes the high-performance, market-leading VxWorks RTOS, tuned for both determinism and responsiveness, with a proven track record in safety- and security-certified environments. Building on VxWorks technology, Wind River Drive provides Adaptive AUTOSAR-oriented software to support customers in developing ISO 26262 ASIL D–certifiable automotive safety-critical applications. Wind River also delivers Wind River Linux and other commercial-grade open source technologies, world-class technical support, and maintenance to help customers stay up-to-date on the latest innovations.
