Intelligent, responsive, integrated - all these terms define the evolving landscape of automotive zonal architecture. To reduce complexity, OEMs have moved to divide the main wiring harness into smaller zones - known as zonal harnesses. Each zone is connected via zone control units so that the physical and functional features are bundled in one area. The Zonal Harness ensures that each zone controller or auxiliary unit is supplied with power, signal and high-speed data. Depending on the customer and vehicle line, 3 to 5 zone control units are used, which connect the different cable harnesses of the individual zones. The smaller wiring harness, unlike a customized wiring harness, can be designed in one variant, which makes automated wiring harness production more likely. The main advantage is the replacement of longer cables and the reduced complexity due to space and weight reduction.
The facts at a glance:
•No customer-specific wiring harness required with corresponding advantages in production and logistics
•Enables weight and space optimization in the main zones
♦High degree of modularization enables efficient production and assembly processes
