In-vehicle Ethernet streamlines OTA updates, diagnostics

Molex has joined hands with Excelfore to streamline its 10-Gbps Ethernet Automotive Network for connected cars. Molex is employing Excelfore’s connected mobility solutions to ensure that high-speed data transmission inside vehicles is highly reliable and that it features prioritization, scalability, and security.

The 10-Gbps Ethernet Automotive Network from Molex boasts different vehicle profiles with end-to-end data integration and prioritization. And for that, it incorporates Excelfore’s protocol stacks and eSync System for over-the-air (OTA) updates, diagnostics, telematics, and analytics-based smart-learning integration.

Molex’s automotive network employs protocol stacks for in-vehicle Ethernet audio-video bridging (AVB) and time-sensitive networking (TSN) run on cameras, video displays, head units, ECUs, and network gateways so that CAN, LIN, and other busses can be reached by Ethernet.

Next, the eSync System can push data via cloud-based eSync servers to the vehicle for OTA software and firmware updates. Or it can pull data for diagnosing and tracking vehicle status and performance.

Excelfore’s eSync System uses a patented Adaptive Delta Compression Engine to optimize compression of OTA software updates and minimize airtime for delivery. All OTA and diagnostic traffic streams are fully encrypted and secure with authentication in both directions.

Moreover, it simplifies troubleshooting and repairs because all system components are accessible from one test port whether the vehicle is diagnosed in a dealership service bay or is accessed remotely by the automotive OEM.
