The location domain realizes the nearby arrangement of wiring harnesses, reduces costs, reduces communication interfaces, and makes it easier to realize automatic assembly of wiring harnesses to improve efficiency. Sensors, actuators, etc. are connected to nearby regional controllers, which can better realize hardware expansion and make the structure management of regional controllers easier. Regional access to central computing ensures the stability of the vehicle architecture and the scalability of functions. Newly added external components can be accessed based on regional gateways. The pluggable design of hardware supports the continuous improvement of computing power, and sufficient computing power supports application software. Iteratively upgrade on the central computing platform. In a study with an OEM, Aptiv found that using zone controllers could consolidate nine ECUs and save hundreds of individual wires, resulting in an 8.5kg reduction in vehicle weight. Weight reduction helps save energy and increases the driving range of electric vehicles. In addition, it is easier to automate wiring harness assembly as the zone controller divides the basic electrical structure of the vehicle into more manageable components.
