Numerical analysis of the electromagnetic interference of a wave inter-vehicle communication system on vehicle electronics

Abstract

Ιnter-vehicle communication systems present an increasing popularity due to their critical, for public safety, as much as attractive and convenient applications. This technological tendency could potentially become hazardous for automotive electronics. The radiated immunity of automotive electronics in electromagnetic fields caused by inter-vehicle communication systems described by the IEEE 802.11p WAVE standard or its equivalents is studied in this paper. The electric field produced in critical points of the interior of a vehicle is estimated by means of full wave Finite Difference Time Domain method simulations. In each simulation, the vehicle-to-vehicle or vehicle-to-infrastructure communication according to the characteristics of the IEEE WAVE standard is assumed.
