Automobile electronic technology application situation

As the combination of the auto industry and electronic industry, automotive electronics industry has been rapid development. At present, the western developed countries of the electronic products in the car's weight of the vehicle manufacturing prices reached 15% ~ 15%, is expected to reach 25% ~ 35% by 2010. Automobile electronic technology not only promote the development of the auto industry, but also greatly promote the development of electronic products market. Modern automotive electronics technology in improving automobile performance, fuel economy, safety, stability and ride comfort plays an irreplaceable role. In particular, the application of automotive electronic technology mainly can be divided into the following four aspects.

1. The power transmission electronic control system

Mainly includes the engine electronic control (including gasoline engine and diesel engine), automatic transmission control (ECT, CVT/ECVT, etc.) and the integrated electronic control of power transmission assembly. Control system is mainly composed of various sensors, actuators and electronic control unit (ECU). Its main is to ensure that the car can always be at their best in different working conditions, and simplify the driver's operation, so as to reduce fuel consumption and emissions, reduce the impact of the power transmission system, reduce the labor intensity of drivers, to improve automobile performance, fuel economy and comfort.

2. The chassis of the electronic control system

Including anti-skid braking and dynamic body control system (ABS/ASR, ESP/VDC), traction control, suspension and high car control system, tire monitoring system (TPMS), cruise control system (CCS), steering (4 ws) control system, drive control system (such as 4 wd). It is mainly used to improve the car's safety, comfort and performance, etc. In recent years, this kind of control system is started, widely used in the ordinary cars.

3. Body electronic control system

Mainly includes the airbag (SRS), automatic seat, automatic air conditioning control, in-car noise control, central anti-theft locks, vision lighting control, automatic wiper, automatic doors and Windows, automatic collision avoidance system, and meet the power management system of electrical equipment. Is mainly used to enhance safety, comfort and convenience of car.

4. Multimedia entertainment and communications systems

Mainly including car multimedia system, the driver information system, speech system, intelligent transportation systems (ts), vehicle navigation system (GPS/DGPS, etc.), computer network system, condition monitoring and fault diagnosis system, etc. Used to link "people - car - external environment information", as well as the coordination of vehicle electronic control function of each part.
