Automotive EMC Testing

1. What is Automotive EMC?

Automotive EMC is a test to prevent unintentional radiation of automobiles from affecting motor vehicles and local electrical and electronic devices, and to protect motor vehicles, passengers, and other vehicle users from electromagnetic waves

Today's cars are made up of more sophisticated electronic components and systems than ever before. Additionally, new advances such as autonomous driving technology are using more and more sensors and electronics to enable connectivity and secure communication. Therefore, automotive electronics testing is essential to ensure that the components are safe and do not interfere with the safe operation of the vehicle. Automotive electronics testing ensures that every vehicle's electronic components withstand rigorous testing and comply with applicable regulatory and EMC testing standards.

2. Major Test Items

There are many test items in the safety field, but only the major test items are mentioned here.

	Name of test item	Summary of test
EMI Electromagnetic Interference	RE (Radiated Emission)	Radiated noise emitted from electrical and electronic components/systems and the wiring harness connected thereto is measured in an electromagnetic wave anechoic test room.
	CE (Conducted Emission)	Voltage Method Measures the henomenon in which electromagnetic noise generated from electric and electronic components/systems is emitted through power and ground wires through the monitoring terminal of the Aritficial Network Current Method Measures the amount of electromagnetic noise generated from electrical and electronic components/systems being conducted to the wiring harness outside the wiring using a Curent Measuring Probe.
	MFE (Magnetic Field Emission)	The magnetic field noiise emitted from electric and electronic components/systems is measured using a loop sensor with a built-in coil.
	CTE (VTE) (Conducted Transient Emission)	Regulates the transient voltage induced in the power line by the inductive load component of the components/systems to be evaluated.
EMS Electromagnetic Susceptibility/Immunity	BCI (Bulk current injection)	As a test method to verify the immunity against electromagnetic waves introduced through the wiring harness of electromagnetic interference signal is applied to the wiring harness using an injection probe, and accordingly, it is determined whether the evaluation part is malfunctioning.
	MFI (Magnetic Field Immunity)	After applying a magnetic field to electric and electronic components/systems by generating a magnetic field/using a coil, it is judged whether or not the evaluation parts/systems malfunction accordingly.
	CTI (Conducted Transient Immunity)	Evaluate the immunity performance of electrical and electronic components/systems against instantaneous transient voltage introduced into the power line.
	ESD (Electrostatic Discharge)	Check electrostatic, immunity to prevent static damage during assembly, transportation, and replacement of electrical and electronic components/systems.
	Handy Transmitter	The immunity performance of electric and electronic components and subsystems against electromagnetic interference generated from wireless transmitters such as GSM phones and general-purpise radios.
