Automotive electronics is moving towards high technology products - components, relays, sensors - Education Industry
Huge demand for space vehicle Amount in the car is undoubtedly the largest component Sensor , Sensor The number and level has become an advanced car control system to measure the level of modern key. At present, an ordinary family car on the internally about hundreds of sensors installed, and the number of luxury cars on the sensor up to 200. Automotive sensor market in 2005 reached 8.45 billion U.S. dollars, automotive sensor market size in 2006 dollars has been Chaobai Yi, speed and position sensors, oxygen sensor, pressure sensors and temperature sensor demand will continue to expand.
Auto parts in the automotive relay is an important electronic components, is second only to automobile electronic sensor applications in automotive products, one of the largest automotive electronic components. Now has become the communications vehicle after the relay's second-largest applications market, the global automotive sales of approximately relay relay for 20% of total sales. Xiamen Hongfa Co., Ltd. Sun Biyu generating sound, said the current amount of automobile relays present rapid rise. Statistics show that in 2006 global sales of 4.22 billion U.S. dollars relay, which relay auto sales 850 million U.S. dollars. Global sales in 2007 will reach 4.4 billion U.S. dollars relay, which relay auto sales 890 million U.S. dollars, an increase of 4.71%. Automotive relay 2010 world market demand will exceed 2.5 billion. Thus, the development of space vehicles is a great relay.
Special Electrical Machines as the other key parts of the car One of each economy cars with about 30 sets of Special Electrical Machines, Advanced Micro Special Motor cars with at least 50 more luxury cars with Special Electrical Machines hundred units. China Electronic Components Association Special Electrical Machines and Components Branch of the Secretary-General Chen Bao said that with the electronic Technology Widely used in automotive, micro and special motors in automotive applications will be more broad, such as information systems, navigation systems, car audio, TV entertainment system, vehicle communication systems, the number of micro-special motor applications have increased. In addition, such as speakers, magnetic components and other components in the automotive application is very broad.
Technical requirements for higher Vehicles have become the important carrier of high technology, the demand for differentiated and diversified characteristics and consumer car more safe, more comfortable and intelligence needs, the requirements of the automotive components accordingly higher. Secretary-General of China Association of electro-acoustic
Wangrun Li said that with more and more car audio grade high technology on the vehicle performance requirements of the speaker are on the rise. The requirements of the car speakers is reflected in: Small, affordable power, wide frequency response, distortion, high temperature humidity, seismic performance, high reliability. In order to car speakers over the special requirements to meet, car speaker manufacturers at home and abroad are working to improve and enhance the technical performance of car speakers, as new designs, new technology and new materials.
In addition, the continuous improvement of automotive technology has been applied makes automotive sensors continuously enriched varieties. Meanwhile, the future emergence of new automotive applications, will bring about a new car with complete sensor. Automatic cruise control for example, need speed, range radar, torque, angular position, 3D cameras and other sensors to provide comprehensive information services; new hybrid car, you may need a new sensor variety.
To industry sources, the sensor future development of new technologies, including new technology, such as MEMS technology, or new design ideas, such as hot-film flow sensor. Recently a new kind of technology is the introduction of magnetoresistive sensors for speed sensors. Automotive sensor technology the future the overall trend is miniaturization, multi-functional and intelligent.
MEMS sensor has been developed rapidly. In the high-end cars, some with a 25 ~ 40 MEMS sensors.
