In the FIAT 7-Z0441 66 standard developed by the Fiat automobile company, a test method is defined for the detection of electromagnetic disturbances caused by electrical and electronic systems in vehicles.
The electronics in cars today constitute a highly complex structure that controls engine emissions, safety and environmental systems, and driver and passenger comfort alongside a host of computer and communication systems.
Automotive electronics today must meet certain electromagnetic compatibility (EMC) requirements so that these electronics are not affected by external electromagnetic interference (electromagnetic interference) or interfere with each other. In order to achieve this, electronics designers for automotive products put more emphasis on these requirements. As a result, electromagnetic interference and electromagnetic compatibility standards are very important for automotive electronic components.
Electromagnetic interference and electromagnetic compatibility problems arise from many different internal electronic systems inside the vehicle. The average car has hundreds of different electronic systems available today. These include airbags, engine and transmission controls, anti-lock braking, cabin environment, navigation, lighting and entertainment. All of these systems are susceptible to interference from external sources or other systems in the vehicle if not properly designed, manufactured and tested.
Electromagnetic interference from different automotive systems is grouped into narrowband and broadband emissions. Broadband electromagnetic interference is produced by electric motors as well as automotive components that generate arcs and sparks, such as ignition and pulse-type systems. Narrowband electromagnetic interference, on the other hand, is produced by all other active electronics in the vehicle. Each of these active systems relies on the transmission of instructions and data via microprocessors, and any unexpected interruption due to broadband or narrowband electromagnetic interference can negatively affect the system's expected function. If this interruption affects a system that controls the vehicle, such as engine or brake controls, the consequences can be very risky. In this respect, establishing and testing standards for automotive electromagnetic interference is crucial.
