The automotive industry is witnessing technological advancements. The swift adoption of autonomous vehicle systems is driving the need for a more intricate electromagnetic compatibility (EMC) system design. With the advent of new technologies, vehicle platforms have become complex requiring reliable electronic devices that function without impacting the vehicle’s security and components. There are several tests to detect electromagnetic interference (EMI) and radio frequency interference (RFI) generated by electrical equipment and devices used in ADAS, drive assist system, and parking assist system.
Technologies, such as ADAS, driver assist systems, and parking assist systems operate at high bit-rate and bandwidth, hence requiring high frequencies for better performances. Each of these systems witness EMI emission, which, under unprotected state, interferes with other electronic systems in the vehicle. Thus, electronic devices used in ADAS, drive assist systems, and parking assist systems must comply with electromagnetic compatibility standards (EMC) and environmental policies to control these EMI. For instance, in order to reduce EMI in vehicles, devices or equipment are coated with conductive coating or EMI shielding are used.
Continuous advancements in technology and improvements in lifestyle have generated the demand for faster and efficient vehicles. Connected vehicles offer navigation, anti-theft, distance monitoring, parking assist, and other systems for increasing safety and catering to customer needs. Such systems make use of high bandwidth and frequencies, which emit EMI. In order to control EMI and comply with EMC standards, devices emitting EMI are required to have resistive coating or shielding. This need to comply with EMC regulations is driving the launch of better electronic devices with lesser EMI emissions.
The Center for Devices and Radiological Health (CRDH), part of the U.S. Food and Drug Administration (FDA), has identified electromagnetic interference i.e. radiation by electronic devices as a public health and safety concern. For instance, EMI with cardiac pacemakers has been a concern since late 1960. The compliance of electronic devices with EMC standards can be considered as a restraining factor for the market. Manufacturers catering to special purpose vehicles in healthcare and defense & aerospace sectors must comply with EMC standards.
