Nowadays, the development of automotive technology mainly focuses on three aspects: vehicle safety, energy saving and emission reduction, and vehicle performance/comfort and convenience. The technological development trend that runs through these three main lines is the electronicization, integration and intelligence of automotive systems. Especially in the field of "electronic chassis", the development is particularly prominent. This technological trend will make the future of the automotive industry a reality.
At the 2013 International Forum on Automotive Electronics and Semiconductor Technology Innovation held in Shanghai, Pan Dinghai, General Manager of Automotive Electronics Technology Center of Shanghai Aerospace Electromechanical Co., Ltd., systematically described some of the key electronic system applications and key core technologies. And the technical development trend is described in detail, especially the development trend of automotive-grade chip technology application and the requirements of automotive electronics for the chip. At the same time, he discussed the development status and existing problems of domestic automotive electronic technology, and put forward thinking and suggestions for the future development and strategy of trying to break through the bottleneck of automotive electronic technology.
Three main lines of automotive technology development
At present, the cost of electronic systems on automobiles may account for 25~30% of the total cost of automobiles, and will exceed 40% in a few years. In 2012, the scale of China's automotive electronics market is expected to exceed 300 billion yuan. On the other hand, the rapid development of new energy vehicles has also accelerated the pace of application and development of electronic control systems in automobiles. Automotive electronic control technology has become the main battlefield for automotive technology development and market competition.
Judging from the current market development trend, Pan Dinghai believes that the systematic, integrated and intelligent automotive electronics technology is the inevitable direction. The three trends are developed along the three main lines of vehicle safety, energy saving and emission reduction and comfort and convenience/enhancement performance. The mainstream of technology running through these three main lines is the electronic, systematic, integrated and intelligent automotive systems.
Let me talk about car safety. Pan Dinghai pointed out that the market and social needs of automotive safety technology mainly come from three factors: the consumer's requirements for safety, the development of the latest safety regulations, and the driver's distraction. “The survey found that 57% of consumers believe that they are important factors to consider when they buy a car to help them avoid driver lanes or lane guidance systems that deviate from the lane. In order to reduce car accidents, many countries have developed The regulations make specific requirements for the safety of automobiles. On the other hand, the application of smart phones, in-car entertainment systems and navigation systems in the car makes drivers more and more distracted, and improper use is likely to cause traffic accidents. Therefore, government regulations and user requirements determine the law of market development. Modern electronic technology makes it possible to avoid accidents and car accidents, or can greatly reduce the loss of car accidents and promote the development of safety technology."
Automobile safety technology can be divided into active safety system and passive safety system. Active safety system refers to safety technologies such as ABS/ESC that can prevent accidents, various driver assistance systems such as collision alarm, lane keeping system, blind spot warning system and rear monitoring system, tire pressure monitoring system (TPMS), electric power assist Steering system (EPS) and body electronic safety systems; passive safety systems are safety technologies such as seat belts, airbags, and rollover passenger protection systems that are used to avoid or reduce casualties after an accident.
Automotive energy-saving and emission-reduction electronic technologies, for traditional energy vehicles, include engine electronic control and management systems, electronically controlled automatic transmissions (ECAT), electronically controlled steering systems, and vehicle start/stop systems. For new energy vehicles, automotive electronic control technology is the basic technical condition for realizing new energy vehicles. In turn, the development of new energy vehicles brings more new opportunities to automotive electronics, including drive motors and drive control systems, batteries. And battery management system (BMS), vehicle electronic control system, thermal management system, EPS or wire-controlled steering system, braking energy recovery system.
