The first is system development, which defines the electrical component functions and signal logic relationships of the entire vehicle platform. Then there is the vehicle topology, and the electrical system of the vehicle platform is planned and segmented into reasonable wiring harnesses. Even before providing detailed wiring relationships and wiring diagrams, EB can determine the connectors required for the harness. At the same time, structural experts began to assemble the connectors in 3D and create the topology of the wiring harness. This helps save time waiting for the principle to be completed, and EB’s central data model enables parallel design of electrical and collusion. Pneumatic designs can also be started immediately because their graphic data (eg: solenoid valves) are also linked to the schematic.
