From Legacy to Zonal Architecture
Legacy Architecture
Traditional car networks use a distributed, feature-based architecture with numerous ECUs and extensive wiring, leading to complexity and higher costs.
Zonal Architecture
Zonal architecture centralizes computing power, reducing the number of ECUs and simplifying wiring harnesses, paving the way for Software Defined Vehicles (SDVs).
Zonal System Components
Power Distribution Unit (PDU)
A core component that handles low-voltage power distribution, protecting subsystems from electrical faults and providing a robust power supply.
Zonal Controller Unit (ZCU)
The ZCU acts as a local hub for sensor and actuator data within a specific zone, managing communication and processing tasks efficiently.
Ethernet Connectivity
High-speed Ethernet, such as the NCV7410 10BASE-T1S transceiver, is essential for the seamless communication required between zones and the central computing unit.
