With the widespread use of automotive electronics, the issue of electromagnetic compatibility among electronic products is getting more and more serious, which directly relates to the normal driving and safety performance of vehicles. In order to ensure the EMC performance of automotive electronic products, the electromagnetic compatibility certification business of automotive electronic products in various countries and regions in the world has conducted extensive and in-depth research.
In the United States, Japan, the European Union and other countries and regions, the automotive electronic products have EMC requirements into the certification management system.
Taking the European market as an example, the vehicles or automotive electronics currently in the 1: 3 European market must pass the ECE regulatory requirements and the EU directives. The content of radio interference suppression is an important part of ECE's automotive technology regulatory structure. Among them, the regulatory RIO part of ECE is the uniform regulation on electromagnetic compatibility in vehicle approval. Among the EU directives, directive 72/245 / EC also specifies the requirements for electromagnetic compatibility
The major testing items and standards for automotive electronics include: Radiated Emission and Conductive Emission (CISPR 25); Conducted Transient Emission (ISO 7637-2); Radiated Immunity and conducted immunity (ISO 11452 series); Static Discharge Immunity (ISO 10605); Conducted Transient Immunity (ISO 7637 Series), etc. Foreign automotive electronics product testing laboratories also have strict requirements, in order to become the three major US car brand contract testing laboratories must pass the stringent A2LA / AEMCLRP certification, although the current domestic foreign-related laboratories have passed the certification, but Chinese domestic laboratories are still rarely able to pass AEMCLRP certification.
