In recent years, due to the impact of the oil crisis and global warming, the issues of energy conservation and environmental protection have attracted global attention. A series of problems such as the slowing economic growth, the gradual decline in the growth rate of car ownership in the world, an aging society, the elderly population and the vulnerable people in transportation, coupled with the demand for subjective and objective factors such as stimulating the development of the automobile industry, have affected the automobile. Industry development.
As the 3C electronics industry has entered a mature period, product demand has decreased, leading to lower gross profit margins. Electronics industry players have fallen into price-cutting competitions. Manufacturers are looking for business opportunities for sustainable operation. The global automotive market demand has become diversified and customized. Traditional mechanical methods can no longer satisfy people's desire to own a car with safety, environmental protection and comfort performance. In recent years, the technology has gradually matured, and automotive electronic products supporting electronic control technology are showing their heads, mainly with various sensors. , Microcomputer controllers, audio-visual entertainment machines, satellite navigation machines, wireless communication and other product application and service methods, providing vehicles and personnel with energy saving and carbon reduction, low noise pollution, comfort, active and driving safety, security, emergency rescue and road guidance, etc. Function, make the car control more humanized, smarter and meet the needs of intelligence.
Automotive electronics can be divided into two meanings. One is the automotive electronic control device. The electronic control device combines the functions of the on-board mechanical system and belongs to the integrated application of electromechanical systems, including engine power and sensor system control (such as image, acceleration, pressure or Temperature, etc.), electromechanical system control (such as electronic fuel injection system, anti-brake deadlock system, vehicle anti-skid control, electronically controlled suspension, electronically controlled automatic transmission, etc.); the other is an electronic device that can be used independently, and the car itself There is no direct relationship with performance, safety or control, such as satellite navigation systems, audio-visual entertainment services and other vehicle-mounted devices.
There are many types of automotive electronics products, and the broad automotive electronics industry covers engine / transmission systems (such as electronic ignition systems, automatic transmissions, etc.), suspension / chassis systems (including power steering wheels, chassis control, vehicle anti-skid control, etc.), body systems ( Including 6 systems including car lights, air conditioning, sunroof, etc., vehicle information and communication, driving safety systems (such as airbags, anti-collision radar, etc.) and anti-theft security systems, including power electronic components that support 6 systems.
Let us take a closer look at the seven characteristics of automotive electronics!
