2003 world car of less than 3%, of which 80% of the increment from China, China's automotive electronics industry's rapid development has attracted the concern of the global automotive electronics industry production growth. This is China's automotive electronics technology and the market situation, difficulties and trends, automotive power management devices and technology development overview, these factors contribute to the automotive electronics design engineers, technical, marketing and sales manager, and the automotive semiconductor products for automotive electronics in China suppliers to seize the development opportunities. Automotive electronics is divided into two categories:
1. Automotive electronic control devices, including powertrain control, chassis and body electronic control, comfort and alarm systems. 2. Car automotive electronics devices, including automotive information system (onboard computer), navigation systems, car audio visual entertainment systems, automotive communications systems, vehicle networks. China's auto electronic industry development and the current difficulties facing China's auto electronic system manufacturers have a certain economy of scale, they are by and or restructuring, etc., into the depot matching system, and gradually enter the international market, supporting high-end cars. In the development of automotive electronics is the rapid development of automotive electronics industry is an important direction.
In contrast, the level of China's automobile industry and R & D capabilities and abroad is still a big gap between the electronic control system. In the face of adverse market environment, China's scientific and technological personnel has not stalled. With the energy situation becomes increasingly tense, the China National "863" plans to actively promote the electronic control systems, automotive electronics and industrial areas of focus of electric vehicles and fuel cell vehicle research: 1. Information: tachometer, engine tachometer and fuel gauge network will be set, diagnosis, and touch-screen digital LCD display, by replacing the vehicle's dynamic information system, "experts think tank" to achieve on-site diagnosis, road autonomous navigation , electronic maps, dynamic display of vehicle location and track playback 2. Energy-saving technologies: high speed when turning the steering wheel is easy, slow turn, the steering wheel is very difficult, which will increase fuel consumption by about 2%.
Development of new electric power steering system is supposed to do the opposite, so that labor-saving and safe driving to save energy. 3. Comfort: Currently, the automotive air conditioning is a machine driven, due to temperature, the driver manual control, the energy problem is serious. Automatic air conditioning system and the development of intelligent air conditioning system will automatically collect internal and external temperature, humidity, sunshine, a series of signals and vehicle speed, according to a certain mathematical model, at any time automatically adjusted to get the best air conditioning mode.
The three studies the application of fuel cell vehicles on the leadership, and is subject to conditions, the gradual conversion of conventional cars. In addition, China's Ministry of Information Industry will focus on supporting the development of six automotive electronics: a unified computing platform trucks, electronic fuel injection system electronic control unit, vehicle traffic monitoring and recording equipment, car audio navigation systems, automotive semiconductor devices and ASIC , intelligent transportation systems.
China's emerging automotive industry in research and product e-business, the major difficulties faced are: understanding the requirements of international standards is not enough, automotive plants and automotive electronics manufacturers in emerging top-down, according to the vehicle configuration requirements of the work of electronic products The business model is not fully established projects. Due to lack of demand for towing vehicles, automotive electronics manufacturers have developed their own functional prototype of the product only on the vehicle factory acceptance testing, test requirements of the supporting manufacturers, the China Automotive Technology Research Center, a senior engineer said that in order to reduce test time and reasons for the high cost of the product to stand the test of time relatively short, the stability and security is difficult to meet international standards.
Meanwhile, automobile electronic products and automobile accessory highly relevant to the emerging Chinese automotive electronics business to scale, it is hard out of the joint venture business model, so it is easy to control the vehicle factory. The combination of these two reasons, it may hinder China's automotive electronics business in a very short period of time, to meet the market demand for products and growth started. R & D process, the automotive component manufacturers to support the domestic production is the control of the joint venture, automotive electronics market does not support the development of China's automotive electronics business of the sound development of certain negative effects of a long procurement cycle, to buy is not convenient, does not meet the specification requirements for more common car problems, Shanghai Automotive Technology Co., Ltd., on behalf of Massey level manager said: "The high-power automotive electronics, high on the supporting cables and equipment than the current environment high requirements, including difficulties of matching. "
On this issue, Tianjin Fujitsu Ten Electronics Co., Ltd. Liang Xue director, said: "China's automotive electronics manufacturers to provide local matching, we are China's rapid development, automotive electronics has just set up a research and development center in Tianjin Fujitsu Ten Ltd., in automotive electronics product design needs with the aim to provide services assembly plant. "and Motorola Electronics Co., Ltd. through line and enjoin managers believe that China's automotive electronics enterprises to participate in the international automotive electronics purchasing the General Assembly, and gradually understand the market requirements and international standards, support from the China's auto electronics industry. Currently, electric power, high voltage power supply safety management system, body electrical control, digital meters, low-speed bus control system, tire pressure monitoring and research and industrialization process alarm systems, automotive electronics enterprises in China have begun to deliver.
China's "national car computing platform project" is expected to overcome the launch vehicle control, driving, information processing, intelligent transportation, sensing, a major implementation of the core technology to third generation mobile communications, high-definition digital television, satellite navigation, intelligent transportation, mobile network applications and automotive electronics and information technology and automobile industry for the development of the formation and development pattern of interaction between the electronic information industry a major opportunity. As the top international provider of semiconductor solutions for cars in China, China's automotive electronics industry is expected to accelerate development. China's major automotive electronics market and development opportunities for safe, energy saving, environmental protection, and intelligence and information is the future automotive trends. China's auto market in China, resulting in the rapid growth of automotive entertainment systems, doubling the market size, market survey, from 2003 to 2006, China's total automobile production in 1200-1600 should be a million or so, car entertainment systems, its size in the 500 market - about 8 million units, mainly to provide OEM support services. Vehicle used as vehicle communication, navigation, audio and video entertainment, network control, integrated multimedia market trends of computer integrated information system platform. Analysis shows that China's large-scale development of automotive electronics market, the current prospects, as shown in Figure 2, with driving safety and small car entertainment and navigation-related information systems that control vehicle, body electronics is automotive electronics market, the main direction of development. 1. Autonomous vehicle navigation systems market, the rapid development of China, Beijing, Tianjin, Shanghai and Guangzhou as the center outward expansion of the four major cities in the spatial extent of navigation electronic map and provide navigation electronic map database, navigation information NavInfo Hugo Sun Technology Co., Ltd. Beijing Company, general manager, said: "At present, the automotive industry standards and Chinese law car autonomous navigation electronic map in the product line has been put into Beijing, Tianjin, Shanghai and Guangzhou four cities." estimated that by 2005, China navigation electronic map covers much of the product will meet the 2008 Beijing Olympic Games and 2010 Shanghai World Expo will have a car navigation products. Car navigation systems by the car GPS (global positioning system) receiver to monitor the current location of the vehicle will be stored in CD - ROM, built-in memory (eg hard disk), digital map data to compare user-defined calculation of the target driving directions, real-time location and route information to motorists. Map of the automotive electronics market will drive demand for the development of GPS, digital map of the storage devices, display devices of the huge demand. Strategy Analytics predicts that the global annual demand for navigation systems will be 4.3 billion units in 2002, 1,220 million units in 2010.
Information and Communications Research Group predicts that by 2010 from the GPS receiver, needs 9.4 million units in 2004 to 3,000 million units. From a technical point of view, a GPS navigation system independent of the old car will face a number of space constraints, car DVD disc mass storage advantage, through the use of DVD player can display the electronic map information, therefore, fast-growing car market is expected to DVD . Information and Communications Research Group in July 2004 predicted that global annual demand for automotive DVD market will be 450 million units in 2004, 2010, 3300 million units. With the global automotive mainly from China, autonomous vehicle navigation systems market market growth, the rapid development of the global market have a significant impact. According to Japanese media reports, the DVD / HDD navigation system is a growing trend in global sales of such systems in China in 2004 expected to exceed $ 10,000,000, but this system is just beginning in 2003, is expected to In 2008 over one million in sales.
Digital map data provider will be in this huge market-driven demand. Now more sensitive to the popularity of electronic map, which may be national security issues. In addition, the car radio receiver technology is moving from analog to digital reception mode to receive the development of software radio technology based on digital signal processors, digital radio receivers will lead the direction of the car, may end AM / FM, the development of satellite digital broadcast television receiver and the receiver, GPS, and even in one integrated communication and other functions. Philips CarDSP solution provides enhanced multi-path adaptive correction and improvement, such as automotive AM / FM radio or digital broadcast-quality audio and video equipment, antennas variety of great significance, worthy of attention. 2. Body for the electronics, automotive electronic and electrical appliances as the number of large development has risen sharply and body weight in order to reduce wiring, network, and the number of bus technology has been greatly in this period of development, our goal is to address the reliability of data transmission and cable car The total length of the long lead to weight gain and automotive electronics subsystems to increase safety and other issues in order to meet the needs of automotive wiring.
International auto giants and leading car manufacturers of semiconductor manufacturing series of vehicle bus standard, including: the Inter-American Development Bank - 1394 and MOST (for Multimedia), FlexRay and TTCAN (wire), can be, the Inter-American Development Bank - C and GMLAN Hong Kong-Shenzhen Western Corridor (and the powertrain control), J1850 and LIN (for Body Control), Keywrod2000 and ISO 9141 (diagnosis). We believe that the development of automotive body networks will bring China's auto electronics industry has a very good opportunity and entry point for the following reasons: 1. It reduces barriers to entry for enterprises. With forest or with a single-chip solution, CAN bus interface, shortening the cycle of enterprises to develop e-business research organization, supporting enterprises lower the threshold to enter the automotive electronics market. 2. In order to improve vehicle comfort and expand the use of value-added space vehicles. Machinery and equipment used in the past, such as automotive air conditioning temperature control, manual control, door locks, windows, seats, interior and exterior lighting, mirrors, wipers, and other subsystems, can be CAN or LIN bus network connecting the body, to have the opportunity to change parts of the manual operation of electrical control, middle and low body cars and light trucks mechatronic control unit gradually. Automotive electronics market, iSuppli senior analyst Nancy Party, said: "At present, the high level of foreign auto body subsystems up to more than 50 domestic mid-range sedan, the body electronic subsystems only 6-7 months, so in the Chinese auto body electronics plenty of room for future development of the electronics industry. "Economic Operation under the Ministry of Information Industry predicted that China's body electronics from 2003 to 1.032 billion yuan in 2007 increased 5.033 billion yuan, an increase of 3.8 times, second only to increase the vehicle information and communication System (2007 4.2 times more than in 2003).
Thus, a LIN / CAN bus interface micro-controller, the electric drive unit, motor control MCU and body electronics, mechanical and electrical components will be implemented there is huge demand. Freescale (Freescale) Semiconductor Automotive business, the Ministry of Culture and Sports Xiaodui, development manager: 1. It is mainly used for diagnosis of ISO9141 and Keyword2000 systems in the automotive electronic control more than the latter. 2. J1850 was originally used only in North America in 2006 or 2007, will stop using, and then go to the CAN bus. 3. CAN forest to the complementary nature of the combination in general, as compared with the CAN bus, LIN-bus control mode is the biggest advantage of lower costs, from the relatively high fault tolerance, CAN bus target applications are high-speed and multi-vehicle two-way data communications. 4. Currently, you can still be cars, buses, upgrade the electronic control of the FlexRay highest reliability, but it is still expensive and not practical application. 5. Is mainly used for streaming audio and video-based optical bus, can not be used to control. Automotive electronics in the automotive and other equipment to promote good. Kang Xiaodui said: "In China, CAN / LIN bus now, the practical application has only just begun, different vehicles may be very different, the basic configuration may have 4,5 nodes, high-end cars may reach more than 50 nodes." Currently, the forest's international car manufacturers, including BMW, Volvo, Audi, Volkswagen, Daimler Chrysler, the giant union support, the body's systems development of electronic networks. Kang Xiaodui said: "the micro-controller, power driver, voltage regulator and LIN physical layer as a whole constitute the LIN interface, single-chip integration of child nodes is now the main trend of the electronic controller." 3. Automotive safety systems of the most robust growth, according to market research company Strategy Analytics report, in the automotive electronics field, strong growth in demand, the annual average increase of 25% or more of a vehicle safety system. DuPont Automotive recent survey shows that most users believe the problem is most needed, the car's safety, than vehicle performance, fuel-efficient car entertainment and more importantly, airbags and ABS are expected to become the standard configuration. Visteon's study also showed that: consumers are most concerned about the safety car. Renesas research reveals mid-range cars: 1996 will be the airbags as standard equipment, the international community since 2002, has two passenger seats, seat belt pre-tensioners and sensor system testing, together with the airbag as standard Equipment
Yu Xian expected to tighten belts, 2006, and sensor systems will be increased to 4, a significant increase in the sensor system is to increase the collision detection capability, improve the car's stability, which may constitute a unified network of airbags. International automotive safety systems market is showing active and passive safety systems development and the trend towards integration, as shown in Figure 4, the road map shown in the development of automotive safety systems. At present, China's emerging automotive safety products, design direction, tire pressure monitoring system (TPMS) develops, automotive electronics, in order to prevent the front, side and rear automotive radar systems are designed to collide, China ABS and airbags in the study just start. Currently appearing on the market tire pressure monitoring system (TPMS) in the fall broadly into two categories: (1) direct-type TPMS, it can be sensors and tire pressure RF chip installed near the tire valve is too high, too low A flat tire or the temperature slowly in the wireless receiver car alarm time exception to prevent puncture. The difficulty of the program in the high reliability requirements, battery life is, anti-vibration system, the reliability of the medium-level problems to a certain extent, then, direct TMPS system uses radio frequency transceiver has no established standard to follow, using manufacturing and wireless remote control alarm door or the same device and frequency (433MHz), the usual practice is very difficult to actually use the same FSK modulation frequency to avoid interference problems, and finally, in the tire on the low-power wireless sensor design has been plagued the industry. Development does not require batteries, wireless sensors is the market demand and development. Currently, the Direct TPMS technology is also divided into active and passive technologies. Infineon's activity system will be installed in each wheel pressure sensors, remote control car to receive a variety of devices, including the RKE RF receivers can be used as a tire pressure measurement components, making it a complete tire pressure monitoring systems integration. Active technology advantages, high degree of technological maturity, the development of the modules are suitable for all brands of tires, drawback is battery-powered sensor module needs, it has life problems. Passive no batteries, tires need to integrate it forward, which involves the tire manufacturer needs to establish a common standard is possible only Siemens and Michelin is developing the technology, there is no mature products have emerged. (2) indirect TPMS tires with ABS speed sensor to measure each tire, which is only an inferred speed of the tire pressure is not enough that the system is not including batteries and other radio waves of a troubled rugged, high reliability, not need to change car tires, in comparison with direct TMPS much lower costs, particularly cars and light trucks can be a way to enter the market directly support the depot. lcd module tft, touch lcd module
