Brief: Environmental protection, low-carbon, electronic, and intelligence have become the characteristics of modern automobiles. Hybrid, fuel cells, pure electric driving systems, and the introduction of a large number of automotive electronic components have brought new challenges in automotive electrical and electronic safety. In recent years, the global automotive electronic and electrical system related technical regulations show explosive development trend. Authorities, OEMs, top suppliers and stakeholders from Europe, USA, Japan and South Korea are very active in the development of global motor vehicle regulations, while Chinese native OEMs are also in the high-speed development and innovation stage, pay attention and study global automotive electronics and electrical new regulations, initiate technical route planning and compliance planning in advance is conducive to vehicle manufacturers and their suppliers to lower compliance risks and costs, as well as to ensure new vehicle models hit the market as planned.
The global regulatory system of vehicle electronics and electrical is quite complex, taking the UN Regulation of the Economic Commission for Europe and EU regulations as examples, the mandatory safety regulations of vehicle electronics and electricals currently include electromagnetic compatibility, high voltage electrical safety, recyclability, cybersecurity, general data protection, software updates, radio equipment directive, REACH regulation, etc. Besides the general regulations above there are more and more specific regulations related to the specific E/E system are published, safety and performance testing and certification requirements are specified. Also, for electrical and electronic systems, if they are related to traditional vehicle structural safety regulations, then they shall also fulfill these regulations, such as interior fittings, external protrusions, etc. The following is an overview of these regulations and typical test items.

IN-VEHICLE TELECOMMUNICATION DEVICE
In-vehicle radio telecommunication devices such as remote keys and using 2G/3G/4G, Bluetooth/WIFI, NFC, etc. need to be certified according to Directive 2014/53/EU.
FUNCTIONAL SAFETY OF COMPLEX ELECTRONIC VEHICLE CONTROL SYSTEMS
Regulations: UNR 13/H, UNR 79 etc.
There are special requirements to be applied to the safety aspects of complex electronic vehicle control systems in several EU/UN regulations, these requirements do not specify the performance criteria for "The System" but covers the methodology applied to the design process and the information which shall be disclosed to the Technical Service, for type approval purposes. This information shall show that "The System" respects, under normal and fault conditions, all the appropriate performance requirements specified elsewhere in this Regulation.
Manufacturers of complex electronic vehicle control systems generally consider the ISO26262 standard during product design and manufacturing.
Recyclability regulation apply to vehicles belonging to categories M1 and N1 and intended to apply for unlimited volume WVTA certificate. This regulation is not limited to electrical and electronic units but applicable for all systems and components of the vehicle, recyclability data, technical documentation shall be reviewed by technical service and type approval certificate shall be issued.
CYBERSECURITY, SOFTWARE UPDATES, GENERAL DATA PROTECTION
Regulations: UNR 155, UNR 156, GDPR
Within the next few years, smart cars’ connectivity is expected to expand and smart cars will become connected to other vehicles, pedestrians and their surrounding infrastructure through information exchanges via V2X communications. This comes with significant cybersecurity risks, as hackers seek to access electronic systems and data, threatening vehicle safety and consumer privacy. The two new UN Regulations, adopted by UNECE’s World Forum for Harmonization of Vehicle Regulations, require that measures be implemented across 4 distinct disciplines: Managing vehicle cyber risks; Securing vehicles by design to mitigate risks along the value chain; Detecting and responding to security incidents across vehicle fleet; Providing safe and secure software updates and ensuring vehicle safety is not compromised, introducing a legal basis for so-called “Over-the-Air” (O.T.A.) updates to on-board vehicle software. The regulations will apply to passenger cars, vans, trucks and buses. They have been in force since January 2021. In the European Union, the new regulation on cyber security will be mandatory for all new vehicle types from July 2022 and will become mandatory for all new vehicles produced from July 2024. General data protection provisions are specified in cybersecurity and software updates regulations as well as other E/E specific regulations, for the interpretation of these provisions OEMs and suppliers shall refer to GDPR.
Regulation (EC) No 1907/2006
REACH is abbreviation of Registration, Evaluation, Authorization and Restriction of Chemical, came into force on 1st June 2007 and effective from 1st June 2008, is applicable for all chemicals, not only those used in factories, but also substances in our daily lives. For example, chemicals in cleaning products, paints, clothing, furniture, electronics, and automotive products all need to comply with REACH regulations.
