Vehicle-to-vehicle communication system EMI characterization on automotive electronics

Abstract

The major issue of electromagnetic immunity of automotive electronics to the radiation of vehicle-to-vehicle systems is the subject of this paper. Inter-vehicle communication systems provide a wide range of new services and applications for vehicular environments, but they are still under development. Although very promising for the future of intelligent transportation systems, they may become hazardous for automotive electronics. A core numerical analysis of the electric field produced by such a system is performed by means of the full wave Finite Difference Time Domain method. The electric field intensity levels in a vehicle due to a vehicle-to-vehicle communication system is estimated for various cases according to the corresponding IEEE standard and compared to the maximum allowed levels for electronic devices.
