There are two SAE standards that apply to EMC. SAE J551 applies to vehicles, and SAE J1113 applies to components (modules). Both are used as a basis for internal standards by automobile manufacturers, farm machinery, heavy equipment, etc.

One of my clients claimed it meant "Even More Money for Consultants." Ouch... Incidentally, automotive EMC problems are among the most challenging we see -- low emissions, rough EMI environment, extreme cost constraints, and more. So when you finally pass the automotive EMC tests, you have done a very fine job of design!

Thank you agk! So the automobile industry also follows the generic standards for electrical/electronic systems? Are there any IEC standards specific only to Automobile electronics industry?

Hi Sanjib http://www.autoemc.net/Standards/StandardsMain.htm gives idea. WTO members to follow CISPER12 vehicle level and CISPER25 component level.IEC 61000-4-2, IEC 61000-4-3, IEC 61000-4-8, IEC 61000-4-21.

A vehicle's ECU can be stopped functioning by a near by powerfull radiation . To safe guard this ECU and other electronic control systems need to be protected from this type of powerefull radiation. Similarly the ECU and the other electronic sub systems radiates EM waves which can interfere with other systems and the traveller in the vehicle may get effected also while the vehicle passes by others may get this radiation. This also needs to be taken care while designing.EMC requirements to be met by the manufacturers.

What are the standards, which define the EMI/EMC requirements for automobile electronics? Are they different from EN55011 (electromagnetic emission) and EN61000-4-2 (ESD),-3 (RF susceptibility),-4 (EFT),-5 (Voltage Surge)... etc. series of standards?

The reason for "EMC stand for exasperating, magic, or confusing" is that people keep thinking EMC is only one single phenomenon. When you read all these EMC articles, please remember there are two types of EMC problems: conductive and radiative

It might be noted that current efforts toward lower power consumption is being implemented in many cases by increased impedance of logic lines thus requiring lower drive current. This trend will make the logic lines more suceptable to RF interferrance. This can be overcome but requires much more attention to this subject than was needed in older designs. The twists and turns of design interplay are interesting as with higher impedances to get lower drive currents you cannot just add capacitive filtering because you need the lower drive impedance go get the speed with that added capacitance. (read it again it'll make sense)Gets fun when you find yourself partitioning your multilayer PWB into compartments to provide EM isolation inside the board before you even get to protecting yourself from the outside world.

Good article, reminding me on many of the hardware layout techniques that must be considered. I hope to read part 2 very soon.

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
