Abstract
In a modern vehicle, the automotive wire harness forms a crucial part of the sensor signal and power distribution system. It is thus important to understand the impact of electromagnetic interference on such harness, in particular its dependence on layout with respect to an incoming electromagnetic wave. The research presented here investigates the induced common-mode and differential-mode currents in various wire harness layouts, as well as the dependence on both grounding and on the harness design involving an unshielded twisted or untwisted pair. The results indicate that for harness layouts with a substantial component along the electric field directions, such current levels can reach up to those that disrupt automotive sensor communication.
