Component Level EMC Compliance Sets the Stage for Safe and Reliable Vehicle Operation
Car, truck, and commercial vehicle manufactures perform EMC testing on their whole vehicles as a final system verification and before their products can be placed on the market. Emissions measurements confirm vehicle radios, communications, and navigation equipment are not degraded by the RF noise from electronic subsystems. High intensity RF fields and ESD (discharge) are directed at the whole vehicle to verify passenger safety and for the protection of other road users.
Component level EMC is critically important because modern vehicles have dozens of microprocessor based modules, a multitude of sensors, communications equipment, and motors. In addition, whole vehicle EMC testing takes place late in the production process, and when nearly all Electronic Sub-Assemblies (ESAs) and components are designed and on their way to production. This means compliance of each individual component on the vehicle must be separately assured, and well in advance of the final vehicle testing.
EMC testing of each and every vehicle component is critically important to reduce the risk vehicle level nonconformities. Elite engineers know this reality and have the equipment, expertise, and qualifications to get the job done on-time and correctly.
