ELECTROMAGNETIC COMPATIBILITY (EMC) FOR THE IVHS FROM SYSTEM ARCHITECTURE TO COMPONENT LEVEL

The problem of Electromagnetic Interference (EMI) afflicts all electrical and electronic systems to some degree, depending on signal and noise levels and immunity thresholds. The effects are potential IVHS degraded system performance whereby the consequences can range from benign or trivial nuisances to possible catastrophic operational failures. This paper identifies potential problems due to EMI sources and the necessity for positive action to provide satisfactory IVHS system performance. IVHS Radio Frequency (RF) links are among the most critical and the most sensitive to electrical interference. For example, the most critical links are certainly those that can affect safety, such as collision avoidance operations. Among IVHS systems likely to be affected by EMI are Highway Advisory Radio (HAR), Closed Circuit Television (CCTV), and Changeable Message Signs (CMS); In-Vehicle Safety Advisory and Warning Systems (IVSAWS).
