With the rapid development of intelligent electronic information technology and the continuous changes in the automotive industry, the global automotive electronics industry has ushered in a golden period of development. An industrial upgrade battle around the application and innovation of automotive electronics technology has begun.
■ Intelligent network connection needs to promote the development of automotive electronics technology Currently, intelligent networked vehicles are one of the important directions for the development of the future automotive industry, and its development space is very broad. As an important foundation for the development of automotive intelligent network, automotive electronics has stood on the cusp. In the face of a market with huge potential, auto electronics manufacturers follow the trend of technology development and “deeply stalking and broadcasting” in various sub-sectors, striving to seize the opportunities.
Qi Hui, deputy chief engineer and director of the fifth development department of the Automotive Engineering Research Institute of China Automotive Technology Research Center, said that the intelligent vehicle technology system mainly includes communication between vehicles and vehicles, communication between vehicles and roads, communication between vehicles and clouds, and involves four commonalities. Core Technology. The first is environmental sensing technology, such as anti-collision warning radar, camera and other sensors; the second is communication technology, including DSRC, LTE-V, RFID and other short-range wireless communication technologies; the third is intelligent terminal systems, mainly based on various operating platforms. The vehicle network terminal system; the fourth is the cloud computing and service integration technology, in which cloud computing is mainly road environment planning, intelligent traffic scheduling, etc., as well as the pushing of some information and service content.
In addition, Qi Hui believes that the key to the development of intelligent network technology is security. “Automobile as a smart terminal device for accessing the network, how to protect personal privacy and data leakage is a common concern of parts and vehicle companies.”
"Today, the development of in-vehicle network is the direct management and control of intelligent terminals, and it is the future development trend." He Sicong, senior technical expert of the vehicle network technology department of Zhejiang Geely Automobile Research Institute Co., Ltd. said. Geely Automobile Research Institute has deeply studied the lowest level technology in the intelligent network connection product application layer solution, and gradually implemented related solutions from electronic devices to chips.
â–  The competition for automotive electronics technology to extend to the upstream sector has become a highly integrated automotive electronics technology. A wide variety of electronic devices and sensors are used on a large scale. At the same time, more and more new technologies for automotive electronics have been developed and applied. The key core technology of automotive electronics has become the key to the future competition in the automotive industry.
Dr. Hua Jianfeng, Ph.D., Department of Automotive Engineering, Tsinghua University, said that the key technologies of automotive electronics mainly include automotive electronic sensors, power semiconductors, multi-core master chips, communication and calibration technologies, and are currently used in automotive core components.
Hua Jianfeng introduced that the original car sensor has a complicated structure and a large volume, and two-channel redundancy is often used to ensure safety on some important safety parts. With the development of technology, MEMS sensors are becoming more and more widely used as the main solution for automotive sensors, and can be applied to switch controllers of high-end models.
In the electronic control chip technology, some leading international companies are at the forefront of the industry. Hua Jianfeng said as an example: "Toyota, Volkswagen and other companies have a common development trend in the development of automotive electronic control chips, that is, the integration and integration of chips, making them smaller in size, smaller in internal resistance, higher in efficiency, and lower in cost. High-end electronic technology control systems are more competitive."
The development speed of automotive electronics is very fast, which brings greater competitive pressure to independent brand enterprises. In the chip industry, competition from the chip itself has been extended to the upstream technology of chip materials and technology principles. In this regard, Gao Hesheng, deputy director of the China Automotive Technology and Research Center, said that the forward-looking judgment of automotive electronics is very important. "Independent enterprises must seize the opportunities of industrial development and constantly think about how automotive electronic products should cater to the development of the automotive industry."
■ Electronic and electrical equipment determines the reliability of the whole vehicle “The reliability of automotive electronic components determines the reliability of the vehicle.” Zhao Bin, the chief engineer of the body accessories room of the Parts Testing and Research Department of Tianjin Automotive Testing Center, said.
At present, under the demand of intelligent development of automobiles and comprehensive improvement of performance, the position of automotive electronic and electrical components and systems in vehicle safety is becoming more and more important. The control system of the car is based on high-end electronic equipment, so the reliability of the electronic control equipment plays a leading role in the reliability of the whole vehicle, and the key control systems are inseparable from the electronic and electrical components. The reliability of electronic appliances has become the focus of enterprise research and development.
Zhao Bin introduced that the requirements for electrical and electronic performance include three aspects. In addition to the basic performance requirements, it also includes environmental performance requirements, that is, the product has strong adaptability to different environmental conditions such as temperature, humidity, vibration, etc., and electromagnetic compatibility. The product is required to have the ability to resist conduction and radiation interference.
These performance and reliability requirements for electronic appliances require a large amount of pre-test verification to ensure. With the extensive use of electrical devices, electronic devices, and programmable electronic devices in the field of automotive control, some new security issues have emerged. Zhao Bin believes that parts and vehicle companies can strictly reduce production and management according to certain standards, which can reduce the incidence of electronic and electrical problems. The ISO 26262 standard is targeted at automotive electrical components, electronic devices, programmable electronics, and other components specifically used in the automotive sector to provide the necessary support for automotive life cycle safety.

Carbon Steel Plate

Carbon Steel Plate is a kind of steel with a carbon content of less than 2.11% and no deliberate addition of metal elements. It can also be called ordinary carbon steel or carbon steel. In addition to carbon, there are also a small amount of silicon, manganese, sulfur, phosphorus and other elements inside. The higher the carbon content, the better the hardness and strength, but the plasticity will be worse. "
