【 摘 要 】

Engine Management ECU plays a vital role in controlling different important features related to the engine performance. ECU is an embedded system which includes hardware and firmware platform for control logics. However, it is necessary to verify its smooth performance by its functionality testing in the Electromagnetic environment for approval. If these requirements are not known at earlier stages, then ECU may not fulfil functional requirements during required automotive electronic test standards. Hence, focusing on EMS ECU, this paper highlights hardware, layout and software guidelines for solving problems related with Electromagnetic Interference (EMI) to comply ISO 7637, CISPR 25 standard, Electromagnetic Compatibility (EMC) to comply ISO 11452-4,5 standard, Electrostatic Discharge (ESD) to comply ISO 10605 standard and Environmental Testing to comply standards as per IEC standards. This paper specifies initially the importance, need and guidelines for reducing the EMI effect on PCB i.e. making ECU more electromagnetically compatible as per automotive standards. The guidelines are useful for the designers to avoid pitfalls at the later stage. After mentioned modifications in the paper, ECU successfully passed the requirements for all standard tests.
