Vehicle EMI Integration Issues Identified by Precompliance Test Methods

Automotive electronics systems are becoming increasingly complex each year. At the same time, interior styling and exterior body trends are causing these sophisticated electronics to be packaged in smaller spaces. As a result, vehicle integration testing has been a focus area for Original Equipment Manufacturers (OEMs) to ensure there is adequate evaluation of such systems prior to mass production. Vehicle level integration testing requires time and extensive resources to perform. The need for performing additional vehicle testing and correcting integration issues can be reduced by performing early precompliance testing. This paper discusses five unique precompliance test methods that correlate to the vehicle that identify EMC issues.
