Abstract
A wiring assembly integrated with magnetic field cancellation components is disclosed. The assembly includes a wiring harness comprising a bundle of wires, some of which carry sufficient aggregate current to generate an above-threshold magnetic field within a vehicle cabin. Connectors at wire ends interface with vehicle electrical components. A probe embedded in the harness senses a portion of the aggregate current and transmits a signal to a control unit. The control unit calculates a cancellation current, which is delivered via a dedicated wire integrated into the harness. This cancellation current mitigates at least part of the magnetic field within the cabin, enhancing electromagnetic compatibility and passenger comfort.

1-11. (canceled)
A vehicle wiring assembly having integrated magnetic field cancellation components associated therewith, the vehicle wiring assembly comprising:
- a vehicle wiring harness including a bundle of wires, at least some of the bundle of wires being aggressor wires configured such that when in use, the aggressor wires carry sufficient aggregate current to cause, in an absence of mitigation, a wiring harness-induced aggressor magnetic field of greater than a threshold level in a region of a passenger cabin of an associated vehicle;
- a plurality of connectors on ends of the wires in the bundle, the plurality of connectors being configured for connecting at least some of the wires in the bundle to electrical components of the vehicle;
- a current sensing probe integrated with the vehicle wiring harness, the current sensing probe being associated with the bundle of wires in a manner enabling the current sensing probe, when in use, to sense at least a portion of the aggregate current, the current sensing probe having an output wire configured for electrical connection to an electronic control unit for determining a cancellation current sufficient to mitigate causation of at least a portion of the wiring harness-induced aggressor magnetic field in the region of the passenger cabin of the vehicle;
- and
- at least one dedicated wire integrated with and running along the vehicle wiring harness, the at least one dedicated wire being configured for electrical connection to the electronic control unit via at least one of the plurality of connectors, to receive the determined cancellation current, and to thereby mitigate causation of at least the portion of the wiring harness-induced aggressor magnetic field in the region of the passenger cabin of the vehicle.
