HARMAN OTA enables automakers and Tier-1 suppliers to adapt to an evolving market by securely managing all in-vehicle software components, including firmware, applications, configurations, settings and maps on head units, TCUs (Telematics Control Units) and ECUs (Electronic Control Units).
In a world of continually evolving electronic devices (e.g., automotive ECUs, embedded modules and M2M devices), it is no longer feasible to visit a dealership every time an update is needed. At HARMAN, we enable the OEM and consumer to update their devices remotely while reducing the cost of data transfer and storage. McKinsey & Co. predicts that the car-generated data market will become a $450 billion business by 2030, further strengthening the importance of data transfer and storage costs.
At the core of the HARMAN OTA Solution is the HARMAN Smart Delta Product. The product offers an innovative approach to performing software updates that improves user experience, cuts costs significantly and reduces the overall time to update devices while ensuring 100% reliability. A pure software-based solution, HARMAN Smart Delta product has the smallest footprint in the industry based on a proven and patented technology. Shipped in more than two billion devices, HARMAN Smart Delta product is the market-leading solution for updating binaries over-the-air.
HARMAN Smart Delta product overcomes bandwidth and memory limitations by extracting only the essential changes between firmware versions, reducing update files size by up to 97% and generating potential savings of up to 97% of data cost. For example, delivering a 2GB image size would cost the OEM about $133/vehicle compared to a 0.2GB sized image at only $13/vehicle with this product. The estimated savings for a fleet of 500,000 vehicles would be $60 million per a single update.
