E/E Architectures and OTA

HARMAN OTA enables efficient, secure updates for high-end and legacy ECUs

Enabling the Software-Defined Vehicle

E/E Architecture Compatibility
HARMAN OTA enables the high-end compute units alongside legacy/low-resource ECUs to be updated efficiently and securely
Independent SW Update Cycle
Transition from domain to zonal makes sensors and actuators independent from central compute node allowing different HW and SW update cycles
Optimize Performance
Distribute OTA orchestration across in-vehicle networks with modern architectures. Handle larger software images without performance issues.
Optimize bandwidth
Data compression and patented differential update generation technology minimize network congestion and update time.
Automobiles now function as mobile computing centers with more than 200 million lines of software code (Statistica). Potent computing power and innovative E/E architectures are required to manage automotive systems at scale. HARMAN OTA enables efficient and secure update of high-end compute units and legacy/low-resource ECUs. OTA orchestration can be distributed across the vehicle network to handle large software images.
