Active System for Electromagnetic Perturbation Monitoring in Vehicles
Résumé
Nowadays electromagnetic environment is rapidly
expanding in frequency domain and wireless services extend in terms of
covered area. European electromagnetic compatibility regulations refer
to limit values regarding emissions, as well as procedures for
determining susceptibility of the vehicle. Approval procedure for a
series of cars is based on determining emissions/immunity level for a
few vehicles picked randomly from the entire series, supposing that
entire vehicle series is compliant. During immunity assessment, the
vehicle is not subjected to real perturbation sources, but exposed to
electric/magnetic fields generated by laboratory equipment. Since
current approach takes into account only partially real situation
regarding perturbation sources, this paper proposes an active system for
determining electromagnetic parameters of vehicle's environment, that
implements a logical diagram for measurement, satisfying the imposed
requirements. This new and original solution is useful for EMC
assessment of hybrid and electrical vehicles.
