The automobile electronic control system by the sensor， the electronic control module， the actuator three major part is composed， divides into the engine electrically controlled technology， the chassis electrically controlled technology， the automobile body safe electrically controlled technology approximately by its development's new The electrically controlled system has made the important contribution in modern automobile various aspects various This article take the chassis electrically controlled technology's in security aerocyst technology as an example， has conducted the research to the auto safety domain in take the electrically controlled technology as the core safety The security aerocyst takes in the automobile passive safety device an important item of equipment， has protected personnel riding on the vehicle's safety Indicated through the massive statistics and the actual material， when the automobile bumps into， can use the safety belt and the security aerocyst correctly may cause the head injury rate reduction 30%-50%， face being injured rate reduction 70%-80% This article through has the safekeeping of security to the security aerocyst movement the time process and related actual carries on the sketchy research analysis to verify the security aerocyst the
With the entry of informative network times is comimg， people are not simply satisfied with Atuo as the means of walking replacement， but to expect it can be closely related life to work， just as we work in the office or at home while we take the Meanwhile， Auto electronic rapid developing is regarded as the revolution of Auto technology E-vehicle developing level is one of the key points to measure modern auto Followed the rapid development of comupter， telecommunication and integrated circuit technology， the typified digital field bus of field instrument and other related instruments widely used， and the complicated live link are replaced by simple live network link， the quality of signal transmission becomes much better than before， so that Auto gradually enters internet In reccent decade， customers have higher quality on comfort， security， eco-friendliness of A To meet these increasing demands， many electronic equipment controlled by computer is sharpely increasing in Auto， as a result of line connection becomes more difficult in Auto， especially in Besides， the quantity of electronic line point shows Inevitably it’ll has some troubles or blocks in So that many new model or high-level model auto is using network technology in the process of research to solve these This essay talks about how network is used in inner and outer auto， refering to the characteristic and standard of inner network used in A While the key point is to emphasise on the main features and using of controlling local area According to driving performance， auto electronic products could be classified as followings: one is Auto electronic control devices， including engine， chassis and body electronic The other is car electronic devices， including motor vehicle information systems， navigation systems， car audio and video entertainment systems， automotive communications systems， internet equipment
The society entered the information network time， the people no longer satisfy to the automobile request one kind of riding instead of walking tool， hoped the automobile is the life and the operating region one kind extends， on automobile on elephant in own office and family same work and At the same time， the automobile computerization also day by day rapidly develops， was considered is in an automobile technological development advancement revolution， the automobile computerization degree is weighs by regarding as the modern automobile level the important But along with the computer technology， the communication technology， the integrated circuit technology rapid development， take the numeral field bus as representative's scene measuring appliance， the equipment massive applications， a tedious scene segment bed sheet succinct field bus network replaces， the signaling quality also greatly enhances， the automobile also starts to march into the network In the near ten years， the user regarding automobile comfortableness， the security as well as the environmental protection and so on each performance request enhances In order to meet the need which these increase day by day， on the automobile the computer controls the electronic electric appliance equipment sharp growth， causes the automobile (is specially passenger vehicle) designs the electric appliance line arrangement to be more and more In addition， because because on the automobile each kind of electronic electric appliance meets the point insertion quantity along with it sharp increase， in the automobile travel process meets the point insertion the breakdown to create on the automobile the electronic electric appliance equipment malfunction question to be more and more In order to solve the above problem， very many new vehicle types (are specially upscale vehicle type) in the development starts widely to apply the computer network This article introduced the computer network technology in the automobile the application basic principle， elaborated the networking in the automobile interior and exterior application situation， introduced the automobile interior network characteristic and the automobile interior network standard， with emphasis narrated the control confined network CAN principal characteristic and the According to the automobile driving quality function influence division， may the automobile electronic products induction be two kinds: One kind is the automobile electronic control， including engine， chassis， automobile body electronic One kind is the vehicle carries the automobile electronic installation， including the automobile information system， the guidance system， the automobile sound and the television entertainment system， the vehicle carries the communications system， the surfer equipment and so Keywords: automotive， computer networks， local area network control， network standards
