Investigation of Real Dynamic Automotive Electromagnetic Environment Measurements

Due to the continuous expansion of technologies onto modern vehicles such as e.g., autonomous driving, wireless communications, electric powertrain etc. the on-board electronic equipment increase rapidly. This results in complex electromagnetic environments at the interior of car cabins. This non-stop implementation of electronic equipment requires further investigation of real dynamic automotive environments so that potential electromagnetic threats caused by internal and/or external sources can be identified and overcome. In this paper, the electromagnetic environment of a combustion engine car is investigated and evaluated. The received values taken inside a combustion engine car are examined following two different techniques: the fixed-position technique and the random-walk technique. The measurements are performed in two different states of the car: parked and on the move. The raw results of all the cases are extensively discussed to address how these techniques can provide information of various real conditions. Later, this information can be used for assuring electromagnetic compatibility and risk mitigation.
