Automobile electronics is the general term of automobile electronic control device and automobile electronic control device.The electronic control device of car body includes engine control system, chassis control system and body electronic control system (ECU).
The most important role of automobile electronics is to improve the safety, comfort, economy and entertainment of automobiles.An electronic control system consisting of sensor, microprocessor MPU, actuator, dozens or even hundreds of electronic components and their parts.
Automobile electronics is regarded as a revolution in the development of automobile technology.The degree of electronic automobile is regarded as an important mark to measure the level of modern automobile, and is the most important technical measure to develop new models and improve the performance of automobile.Automobile manufacturers believe that increasing the number of automobile electronic equipment and promoting automobile electronics is an important and effective means to seize the future automobile market.
According to statistics, from 1989 to 2000, the average share of each vehicle's electronic device in the total automobile manufacturing cost increased from 16% to more than 23%.The number of single-chip microcomputers used in some luxury cars has reached 48, with electronics accounting for more than 50 percent of the vehicle's cost.
According to the influence on the performance of automobile, automobile electronic products can be divided into two categories: one is the automobile electronic control device, which should be used in cooperation with the mechanical system of the vehicle, namely the so-called "electromechanical combination" of automobile electronic devices.They include engines, chassis, and electronic body control.Such as electronic control fuel injection system, anti-lock braking control, torque, traction control, electronic control suspension, electronic control automatic transmission, electronic power steering, etc., another kind is on-board automobile electronic device, vehicle-mounted automotive electronic device is used in car environment to be independent electronic device, it has no direct relationship and the performance of the car itself.They include car information system (driving computer), navigation system, car audio and TV entertainment system, car communication system, Internet equipment, etc.
In order to reduce the number and weight of connecting wires, network and bus technology developed greatly during the rapid increase in the number of electronic and electrical devices in cars.Bus technology is to connect various automotive electronic devices into a network, through the data bus to send and receive information.Electronic devices can provide data services for other control devices in addition to completing their respective control functions independently.The networked design simplifies the wiring, reduces the number of electrical nodes and the amount of wires, simplifies the assembly work, and increases the reliability of information transmission.Any electronic control device can be accessed through the data bus, and fault diagnosis can be made by reading fault code, making the whole vehicle maintenance work easier
The application of automobile electronic technology will make the automobile more intelligent.The intelligent vehicle is equipped with a variety of sensors, which can fully perceive the condition of the driver and passenger, information of traffic facilities and surrounding environment, judge whether the passenger is in the best condition, whether the vehicle and person will be in danger, and take corresponding measures in a timely manner.
