Vehicle Domain Controller
A high-performance computing unit that consolidates multiple ECU functions.
Domain controllers replace dozens of smaller ECUs by centralizing processing power into fewer, more capable units. They manage specific domains such as powertrain, body, or ADAS. This reduces wiring complexity and improves software efficiency. Domain-based architectures pave the way for centralized computing and easier OTA updates. High-speed networks like Automotive Ethernet support their operation. Future vehicles may use one central computer for all domains.
