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
As the society develops， more and more cars drive in ordinary Chinese Admittedly， cars bring us much convenience and improve our life a lot However， there are also many proplems arisng in daily life，such as traffic jams and traffic accidents， which do lots of harm to families and the whole Every year many people get hurt or lose their lives in traffic We students should pay much attention to traffic safety when walking near the First， we must obey the traffic It is good to go along the sidewalk and wait for the green "walk" Second， before going across the roads， we must look both ways There is no need to Third，we should never play on the Fourth， we can try to pe
A rapid increase in the consumption of fossil fuels such as oil and coal seen after the industrial revolution has resulted in a rise in temperature， which exerts an influence over the ecosystem and increases wind and water The emission of CO2， which represents a typical greenhouse gas， has been increasing since fiscal 1990， in ordinary households and in the transportation Resources used for automobiles are roughly divided into oil and metal For oil， which has been supporting the automobile society， the time remaining before depletion is being prolonged， but in view of increasing consumption， the absolute amount may For mineral resources， it is said that the amount presently mined per month greatly exceeds the total consumption of mineral resources before the beginning of the industrial revolution! The ozone layer surrounding the earth absorbs most ultraviolet rays in the sunlight and thus protects the living creatures on the The use of CFC-12 for automotive air conditioners， which destroys the ozone layer， was fully discontinued in 1995 but there is still a problem of how to collect and completely destroy CFC-12 from end-of-life air Some people think that the automobile has improved modern Others think that automobile has caused serious What is your opinion? Use specific reasons and examples to support your The advent of automobile has made the world There are two aspects of change: advantages and Some say that the automobile has improved modern life while others think hat automobile has caused serious I myself endorse the first opinion because I think its advantages are helpful for our modern First， automobile has a very important standing in With the appearance of it， a new industry was This industry has increased and broadened quickly for many It is so important that number of automobile can be produced will evaluate the economy ability of one For instance， Japan is classified in the top richest countries in the world because of its fast growth industries especially， automobile Besides， when look at a car， we can see that it reflect many others achievements of mankind such as: petrol， metal， fashions and so The development of automobile industry will lead those industries to grow with On the other hand， automobile- producing system creates jobs for many people in the world so it distributes stable lives for these Second， not only important in economic， but it is also useful for people ' Automobile can take us to far places much quicker than It makes us not feel difficult and complicated when wee want to go or travel to another It also saves time， money in moving for us both in far or near Besides， it has many other For example， it can help people carrying small or cumbersome things from one place to another To summarize， I want to say that I think automobile is one of the most exceptional inventions of mankind because of its benefits However， automobile has only advantages， it also has disadvantages but if without it， our life will be more difficult and uncomfortable
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
