Feature Selective Validation of Automotive EMC Pre-compliance Tests

Abstract

The pre-compliance tests of electromagnetic immunity are at present a crucial issue for all major automotive manufacturers. In current practice, there are two basic ways to implement these tests. The first one is based on significant simplification of measurement methods and the subsequent transformation of results for relevant estimation of certification measurement results. The second is based on the application of numerical methods and the calculation of the electric field intensity distribution in the car body. The question, however, remains the degree of correlation between these methods, especially when confronting the results of certification measurement. This article brings insights from the field of analysis as to the ability of these methods and Feature Selective Validation to the automotive environment to carry out an objective and quantitative evaluation of the results obtained.
