EB cadian Sync

Continuously improve vehicle functions and react fast to security issues through software updates OTA

A connected, but not updatable vehicle is a huge cybersecurity threat. Therefore, vehicles need to be updatable over the air. Apart from security, consumers are used to the short innovation cycles as offered by their smartphones and computers. That is why over-the-air updates are becoming the method of choice for distributing everything from infotainment system features to operating system security patches and ECU updates or configuration changes.

The task of updating critical vehicle functions places high demands on the security and reliability of the processes used for this purpose. Signal-based communication in Classic AUTOSAR has been replaced with service-oriented communication in Adaptive AUTOSAR. With this system architecture, new applications can be integrated into the entire system more easily.

In connection with OTA updates, Adaptive AUTOSAR provides key functions as standard for purposefully updating functions and components. While Classic AUTOSAR has always required a full update of the application software, Adaptive AUTOSAR supports differential updates.

Key features of EB cadian Sync

 

Meeting requirements of multiple platforms

  • The EB update master is available for a wide range of operating systems, including Linux and Adaptive AUTOSAR.
  • Independent of the preferred platform, the update master provides the seamless integration into the OTA update environment.

 

The back-end is a service platform

  • Scalable, modular, and agnostic back-end solution for fleet, software, and campaign management
  • Can be seamlessly integrated into your system architecture
  • One platform with the same user interface concept for different services

 

Save bandwidth, data traffic, and increase success ratio

  • Two-step campaign approach to reduce bandwidth usage by eliminating unnecessary downloads. A mismatch between the expected and the existing vehicle configuration will be detected and resolved.
  • EB is supplying a delta update solution from Argus that inherits patent-pending differential algorithm. In certain hardware environments, the delta update does not even require an adaption of the update target.
  • With A/B updates you can achieve a zero downtime of the vehicle for the whole update process.
