INVESTIGATION OF ELECTROMAGNETIC INTERFERENCE EFFECTS ON MOTOR VEHICLE ELECTRONIC CONTROL AND SAFETY DEVICES

The report describes the results of a study to investigate, identify, and analyze the potential problems of electromagnetic interference from all sources (internal and external to the vehicle) that may cause malfunction of motor vehicle electronic control and electronically actuated safety devices. This program accomplishes an analysis of inter- and intra-vehicle energy transfer and coupling by computer simulation, using DOD developed modeling techniques that have been employed for a wide range of EMC/EMI design and evaluation support problems. These applications have included aircraft, spacecraft, and advanced surface ships. A computerized circuit analysis model adapted from the IBM Electronic Circuit Analysis Program (ECAP) is used to assess susceptability of representative types of electronic components and subsystems typically used in automotive electronic applications. A preliminary EM environmental source file is provided based on a literature search of vehicular internal noise sources and worst case external electromagnetic field descriptions. Validation test plans and preliminary EMC guidelines for automotive electronics are summarized.
