Unità di Controllo Zonali e Distribuzione di Potenza a Stato Solido

AutomotiveNodes definisce lo standard hardware e firmware per i nodi gateway zonali (ZCU). Sostituendo i relè meccanici con eFuse al silicio configurabili e migrando le sottoreti CAN/LIN su Ethernet 10BASE-T1S, riduce il cablaggio del 30% e offre protezione dai cortocircuiti in microsecondi.

Superamento delle Scatole Fusibili Centralizzate verso la Distribuzione a Stato Solido

I cablaggi tradizionali instradano centinaia di conduttori in rame attraverso paratie verso la scatola fusibili centrale. AutomotiveNodes posiziona gateway intelligenti agli angoli del veicolo, impiegando MOSFET di potenza intelligenti (eFuse) che analizzano i carichi e comunicano via Ethernet a coppia singola.

Core Engineering Areas

• Smart eFuse Power Distribution — Replacing thermal fuses with intelligent silicon MOSFET switches that detect overcurrent events and isolate short circuits in under 10 microseconds.
• 10BASE-T1S Automotive Ethernet — Deploying IEEE 802.3cg 10BASE-T1S multidrop topologies to connect up to 8 sensor nodes on a single unshielded twisted pair without switches.
• Zonal Actuator Virtualization — Publishing local zonal motors, pumps, and solenoids as SOME/IP or REST services via COVESA vehicle signal specifications (VSS).
