Electromagnetic Susceptibility Testing for Earthmoving Vehicles

The need to design and produce reliable and properly functional electronics in vehicles in recent years has placed a high level of emphasis on testing for Electromagnetic Susceptibility (EMS) of vehicle electronics, both at the component and vehicle level. This has come about from the increased usage of complex vehicle electronics such as emission controls for engines, vehicle performance monitoring, and electronic transmission systems are just a small sampling of application for vehicle electronics. To design and to produce vehicle electronics that are not susceptible to the electromagnetic environment that the vehicle can encounter, an organized and structured test plan, test procedures and facilities must be established. This paper describes a comprehensive approach to effectively test, qualify and analyze the Electromagnetic Sysceptibility of vehicle electronics both at the component and vehicle level.
