In-Vehicle Data Fabrics & Multi-Gigabit Zonal Backbones

Transforming legacy point-to-point vehicle wiring harnesses into a consolidated high-bandwidth data fabric. Zonal hubs aggregate sensor feeds and actuator buses over redundant multi-gigabit trunks to central compute clusters.

Replacing 5 Kilometers of Copper with Unified Zonal Multi-Gigabit Trunks

In traditional domain architectures, every sensor and ECU requires dedicated point-to-point cables routed through the chassis, adding over 50kg of wiring weight. SDV zonal data fabrics place compact zonal gateway hubs at the corners of the vehicle, digitizing local sensors and bridging all payload over redundant 10Gbps Ethernet and PCIe switch meshes directly into central compute.

Core Engineering Areas

• Zonal Data Aggregation — Zonal controllers act as localized protocol translators and power distribution hubs. Instead of routing dozens of analog lines to the dashboard, a front-left zonal ECU samples local ambient lights, radars, and wheel speeds, streaming aggregated data to central compute over redundant 10Gbps Ethernet rings.
• Multi-Gigabit Ethernet — Autonomous driving perception stacks require raw, uncompressed sensor feeds to maximize neural network detection accuracy. IEEE 802.3ch defines physical layer standards for 2.5G, 5G, and 10G transmission over single twisted pairs, providing the throughput needed for multi-camera surround vision.
• Unified Data Abstraction Layer — Software developers cannot write code directly against raw CAN matrix signals or analog voltage taps. The SDV data fabric abstracts actuators and sensors into uniform APIs. Whether an application runs on an infotainment SoC or an ADAS accelerator, vehicle telemetry is queried through zero-copy data streams.
