The delta update downloads only the differences between a new version of the software and its prior version, thus reducing the amount of data (small size binary delta) transmitted. The full new version of the software is then reconstructed locally. For millions of vehicles that need regular software updates, delivering such delta updates is an effective mechanism to reduce airtime requirements, and cloud and transmission costs.
The solution is highly flexible and can be quickly and effortlessly integrated with the existing ECU infrastructure of various OEMs and Tier-1s. By analyzing large volumes of data generated by the ECUs of vehicles, it can enhance operational efficiencies and user experience manifold.
Other salient features of this solution are:
Generation of smallest possible delta
In-place update for faster performance
Adaptability to various ECU characteristics
Analytics and reporting for the real-time vehicle status
Improved performance of software upgrades regardless of ECU specification
KrishKupathil, Head â Digital and Hi-Tech, QuEST Global, said, âWith the recent developments in the connected vehicle ecosystem, automobiles have become increasingly complex. These vehicles require regular updates with new features and versions throughout their lifespan. Currently, the upgrade process is tedious with a lot of manual intervention involved. This disruptive and innovative FOTA blueprint solution not only ensures faster time-to-market for OEMs through the quick and efficient deployment of value-added services but also reduces software upgrade cost significantly.
