Best Practices for Design Rules in Vehicle-Level EMI/EMC Compliance

Authors- Sanket Bhor, Anil Joshi

Abstract-Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) are critical considerations in the automotive industry, directly affecting vehicle performance and regulatory compliance. This paper presents a comprehensive analysis of EMI/EMC challenges encountered across all vehicle fuel Platforms. Through detailed case studies, the paper identifies common sources of emission noise, explores rectification methods, and documents key lessons learned to enhance design rules and compliance. The study covers issues such as improper harness routing, insufficient grounding, and earlier release electronic components, which lead to emission noise across different frequency ranges. The findings underscore the importance of meticulous design practices, including proper routing, shielding, grounding, and the use of up-to-date hardware and software, in achieving vehicle-level EMI/EMC compliance. This work aims to provide practical guidance for automotive engineers and designers, contributing to the development of vehicles with improved electromagnetic compatibility.
