Abstract


With the increasing car ownership in today's society, it is more and more high car. The various characteristics of safety, environmental protection, intelligence, comfort, entertainment and other requirements of to promote automobile technology rapidly to digital, information-oriented development, and thus control, communications and network requirements are increasingly complex. Traditional car \Draw on the computer network and on-site control technology developed on the basis of a specific data communication technology for automotive - automotive bus has some car applications, using a dedicated data harness these buses, car ECU unit between data sharing. These buses require the use of specialized data harness, and the vehicle's ECU unit on the data transmission requirements are not consistent, which need to be in the car while arranged several different data networks. This increased while reducing vehicle harness and car data harness. This is bound to increase the manufacturing cost of the car, maintenance is difficult and lead to instability on the car within the data transmission. Therefore, the study of the theory of cable carrier data transmission for the car, trying to not increase the car's wiring harness on the basis of data sharing between the car ECU. The study object is the cable car carrier communication system, the following major elements: (1) analysis of the advantages and disadvantages of using power line carrier communication car might also analyzed the need to solve the problem of power line carrier communication within the car . (2) analysis of the mechanism of the electromagnetic environment of automotive electrical work and automotive electromagnetic interference generated manifestation of its car carrier communication may cause. (3) analysis of automotive cable carrier communication principle, to establish a theoretical model of the car carrier communication system, the channel characteristics of the car carrier communication system. (4) to achieve a wireline carrier communication part of applications in the automotive, design a cable carrier control system based on DTMF signals, for automotive lighting systems. On the basis of theoretical studies, data communication of power line carrier within the car. To digital and information technology development for the automotive, provides a new way of information transmission.
