Car Electronic Interpretation Today’s society has entered the era of information networks. In this era, people want cars not only as a means of transport exists, but hope that it will become a life and an extension of the scope of work. People want to stay in the car or even just stay at home as his office, to keep listening to the radio, telephone, Internet, dealing with work and other chores and so on. In this case, the automotive electronics began to play an increasingly important role. With advances in digital technology, automobiles into the multimedia age will be. The media is an important part of automotive electronics. For example, scientists have developed the car using windows operating system, computer multimedia system, with information processing, communications, Navigation, Security, speech recognition, image display and entertainment features. In the foreseeable future, cars will be equipped with automatic navigation and driver assistance systems, as long as the driver to enter the car driving destination computer, car traffic would be along the best routes and destinations. In addition, it can be manipulated speech recognition system, the various facilities inside the car, while driving the car to listen to music and relaxing TV And can be scheduled online table, tickets, etc…… make your car truly become “mobile homes.” Automotive electronics is automotive body electronic control devices and automotive electronic control unit of general vehicles. Auto body electronic control devices include the following parts: engine control systems, chassis control systems and body electronic control system (body electronics ECU). Car automobile electronic control unit includes idling and anti-block braking system, air suspension control system as a whole, car, bus, trailer overall control systems, electronic devices, these systems are a common means of transport in overload protection, road and braking security when they meet the requirements of international practice. Major component of automotive electronics 1, power control system: includes engine management control system, power steering, AT Control and ACC. 2, safety control systems: including airbags, ABS / ASR with SAFE-BY-WIRE. 3, Body Control System: including switch control, lighting control, security systems, door control, window control, wiper and other body electronic control. 4, traffic control system: includes meter, air conditioning and chassis control systems. 5, Information Systems: including entertainment, mobile communications, GPS Navigation and information processing systems. Automotive Electronics Technology in the increasing role of the car, from the beginning of the turn flash, electronic generator regulator to electronic instruments and electronic fuel injection system ECU everywhere. In Automotive Safety Side, ABS brakes and airbags can not do without electronic technology; in secondary driving, Parking sensor, Elevation measurement, electronic compass, GPS satellite positioning can not be separated electronic. Now more advanced vehicles, automotive parts occupancy cost ratio of more than 20%. The car is coming toward the low power consumption, heat engine electric hybrid direction. These programs are invariably a key technology in electronic technology. With the Chinese and foreign automobile manufacturers in the form design capability and overall ability to close assembly, automotive electronics also will be selling a new generation of cars the focus of differentiation, it has thus become the focus of future automotive industry. Classification Automotive 1, the automotive electronics industry, the functionality, requirements, and the complexity of the broadly divided into two systems: one control system, first entertainment system. Entertainment system is what we usually see the car TV, CD, VCD, DVD, navigation, display and other entertainment facilities. This part of the security requirements are relatively low, and similar products and household differences in the overall function of small chips and programs abound, relevant data and information are also more abundant. Most automotive companies are now manufacturing this part of the product. Control system into the high threshold requirements, security requirements are also high, technology is relatively complex input is quite high, and it lasts longer. In recent years, the control system’s input-output ratio is almost zero. Core technology?? Such as engine control systems, body control system is all controlled by a few foreign corporations. Currently there are only the Grand Scholar, Siemens, Delphi and other large-scale production of several companies in Taiwan who do not have the business. On the whole, entertainment system is a low entry threshold, less investment, profit is also an accelerating pace. Of course, there are more competitors, a single relatively small profits, competition more intense, relatively limited, and many other negative factors. Single control system is relatively high profits, little few competitors, but the investment is relatively high, difficult and profit cycle is relatively long, and we do not have the relevant experience, and thus its development also requires a fairly long historical period. 2, according to the role of car performance impact of automotive electronic products can be grouped into two categories: automotive electronic control devices, and the other is a car car electronic devices. Automotive electronic control devices and vehicle body should be used in conjunction with the mechanical system, the so-called “mechanical and electrical integration” of automobile electronic devices, including engines, chassis, body electronic control. Such as electronic fuel injection systems, antilock brake control, anti-skid control, traction control, electronic control suspension, electronically controlled automatic transmission, electronic power steering and so on. Car Auto electronic devices are in the automotive environment is independent of the use of electronic devices, and the car itself has no direct relationship between performance, including vehicle information system (trip computer), navigation system, Car Audio And television entertainment systems, automotive communications systems, Internet equipment. Throughout China’s auto electronics industry, basically no one can have input in these two areas of the company, almost all of all is the production of electronic entertainment products. Although there are several specially for control systems, but only the depot and related cooperation, auxiliary products for production only, or a large company, a subsidiary or holding company. So, wants the moment in the automotive electronics industry base, the main competitors are those companies that manufacture automotive entertainment products, such as previously installed Hangsheng market-based, Siemens, Visteon, after the installation market-oriented Huayang, custard, and the lucrative passenger market Xiahua, Chang-Yu. Control system does not currently exist rivals, largely because of the domestic mass market products in this area, but said earlier, several companies
