Car Electronic Product Overview Recent years, more stringent safetyEnvironmental protection Technical regulations and demanding individual users use requirements allows manufacturers to rely on electronic technology continues to improve its performance, can be made in automotive technology advances are inseparable from each of the electronic technology in automobile applications. Electronic technology has almost down to the car all the systems, electronic products account for the proportion of vehicle cost has increased annually, and some reached 40% ~ 50%. Automotive electronic devices and non-vehicle sub-two parts, car, car auto electronic devices in the automotive environment is independent of the use of electronic devices, it and the car itself is not directly related to the performance, including multi-media audio, Navigation Systems. As long as the use of vehicles to meet the environment (Electric Environment, electromagnetic environment, mechanical environment, climate and environment, chemical environment) requirements can be installed. Non-board electronic devices associated with the computer control system of electronic devices, their high technology content, have a direct impact on vehicle performance, there are three main areas: 1) mechanical and electrical integration of the engine, chassis, body, and other electronic control systems in electronic devices: such as the ECU, sensors, power semiconductor devices. 2) for monitoring and alarming of a simple electronic control systems such asTire Pressure Monitoring System (TPMS), Parking sensor And so on. 3) to reduce the car around the connection, the sharing of data and rapid exchange with distributed control unit constructed of automotive-based network. Such as CAN bus, LIN bus. Domestic and international automotive electronics standardsChemical industry As is also mainly directed against non-vehicle automotive electronics devices.International Automotive Electronics Standards Status and Development Trend In the ISO, SAE, JASO and other international and foreign advanced standards in the automotive electronics standards in the fast increasing, closely tracking the development of new technologies, the car, greatly facilitate the electronic technology in the automotive application. As a car producing countries, the United States the world leader in automotive technology standard, auto regulations and standards in the world, has a broad impact, SAE standards for automotive electronics standards first appeared in the late 80s, the standard system in recent years, very many of the amendments fast, especially in the network communication protocol standards by the national attention. ISO/TC22/SC3 for automotive electrical and electronic technology in the field of standardization, the Committee has become one of the most active and largest organization of work items, the current ISO/TC22/SC3 focus mainly involved in connecting the circuit network devices (such as electrical connectors, cables, connectors, fuses, intelligent switch), connect the controller node of the communication network and ensure network connectivity Electrical and Electronic Equipment work of the electrical and electronic equipment, environmental conditions, electromagnetic immunity and diagnostics standards. International Automotive Electronics Standards development trends and electronic control systems and electronic control system to connect the network involved a wide range of relevant, basic aspects of the development of strong, specific terms, including automotive, electrical and electronic equipment, environmental conditions, network communication protocols and diagnostic agreement, such as electromagnetic immunity.
