Abstract
Two of the most commonly exercised standards for electromagnetic compatibility (EMC) by automotive engineers are CISPR 12 and CISPR 25. While CISPR 12 is imposed as a regulation to ensure uninterrupted communication for off-board receivers, CISPR 25 is often applied to ensure the quality of services of on-board receivers. Performing these tests becomes challenging until the vehicle is prototyped which may prolong the production time in case of failure or need for modification. However, conducting these tests in a simulation environment can offer more time and cost-efficient ways of analyzing the electromagnetic environment of automotive vehicles. In this paper, a computational approach is proposed in order to predict electromagnetic disturbance from on-board electronics/electrical systems using 3D computational electromagnetic (CEM) tool; Altair Feko. The presented study elaborates on radiated and conductive emission simulations performed for both vehicular and component/module level EMI testing according to CISPR 12 and 25. A high-frequency dynamic circuit network of a DC wiper motor is considered as a source of emission while different receiving antennas have been used according to regulation. A study is also conducted by analyzing effects of different types of cable harness on radiated and conducted emission.
