Under the sudden change of competitive environment, the economic cooperation as a part of survival strategy is being a big issue among countries. There was much discussion based on the geological adjacency as well as cultural homogeneity regarding the economic cooperation of three countries, Korea, China, Japan. It has been also known that major trade countries of the world concluded the treaty of region trade, then extended the number of export, and drew a success in foreign direct investment. It can be considered that Korea will play a major role in the three countries' automobile industry based on Japanese demonstrated technology, Chinese resources, market and experience with their economic cooperation. Therefore it is expected that a big result will be achieved throughout such a role play of each country. This paper has a purpose to light up the distinctive quality and the present condition of each country in automobile industry, and to promote the foundation of three countries' economic cooperation. It is convinced that the economic cooperation of three countries, Korea, China and Japan in automobile industry, will play a great role in the world automobile market.

Recently an automobile industry is concerned about an automobile wiring harness system. It means that development of component modules is on the increase. An importance of the connector in one part of the modules will be enhanced. A connector is made of P.B.T. (Poly Butylene Terephthalate). PBT is resistant to the high temperature. This paper deals with thermal strain of connector. According as temperature increase, effects of the temperature and thermal strains give an analysis of the deformation using ABAQUS. This apparent thermal strain results actually from the variation of temperature. Being based on this analysis, axiomatic design applies to design parameters of the connector. As compared with CAE analysis, a performance improvement makes certain of the truth of the matter.

Most of companies related to the area of B2B electronic commerce are making their efforts to innovate their existing business process into new designed process based on the concept of virtual enterprise. Virtual enterprise can take on many forms and definitions. Nevertheless, the rationale for this business model is clear cooperate to compete, the virtual organization advocates collaboration, partnerships, alliance and similar ideas. This studyintends to suggest an empirical clue to test several hypotheses related to the influence of environmental. organizational, and technological factor to the successful implementation of virtual enterprise in automobile industry. This research surveyed 91 corporations in Korean automobile part industry. Among those samples 86 data of corporate general managers turned out to be statistically valid. This study performed the factor analysis, Cronbach-alpha test. Pearson correlation analysis for testing the validity and the reliability of this research. The results of factor analysis and reliability test indicate that thirty issues to be surveyed are to be grouped into nine factors. The result of multiple regression shows that the influencing factors of eight independent variables on a dependent variable are cooperation between partners, information intensity, IT compatibility, IS maturity. The partners in the strategic alliance will have to trust each other in carrying out their designated roles and responsibilities. and supplying the correct information critical for creating value in virtual business environment.

The single sourcing policy, in which an automobile manufacturer purchases identical or similar parts from one supplier, has an advantage of scale economy. Meanwhile, multiple sourcing policy, which allows procuring similar parts from multiple suppliers, has benefits of dispersing risks and promoting competition among suppliers. This paper analyzes the procurement policies by presenting a model of the Japanese automobile parts trade. It concludes that maturity of technology involved should be taken into account besides above-mentioned factors which have traditionally been recognized. For parts produced using evolving technologies, the single sourcing enhances purchaser’s benefits because of the scale economy in learning process. In the meantime, multiple sourcing is more beneficial to the purchaser if the parts are based on mature technologies. In either policy, if the technology involved is evolving, motivating suppliers by returning a great part of cost reduction as a reward to them may eventually increase profit for the purchaser. The conclusion supports the situation where the number of suppliers is being cut down as the trend of modularization and system deliveries of parts progresses in the auto parts industry, and suggests that returning part of benefits to parts suppliers may be encouraged from the viewpoint of auto manufacturers’ own interest.

In this paper, a telematics service platform, which supports the management and diagnosis of automobile and controls the automobile's convenience equipment is designed and implemented. Using the service platform, telematics software can be developed independent of the lower part of automobiles's network devices, each hardware devices, and wireless network devices. The platform classifies each device's service and provides it with the fixed form of API(Application Programming Interface). This API consists of the wireless connection for a mobile device, the CAN network for controlling an automobile, the receiving part of GPS data for location base service, and the message parser for different data formats of different network.

As time goes by, ultrasonic wave is getting important and new technology, which is adapted to ultrasonic wave is used to industry such as home appliance, automobile, and high-tech industry. Especially, ultrasonic wave is used an alarm device whether there are things at the rear of I. It's do important device in automobile system because it can prevent car-accident from inattention of the driver. Actually, there has already been lots of the alarm device. But it's expensive and so difficult to set the device. So almost driver don't set device at their automobile. We focus on these problems. We want to make cheap md easy setting device. Ultrasonic wave sensor emits Ultrasonic-signal at outgoing part and receive part accept the signal. Sensor analyzes the signal and Distance is displayed on LCD of device. The device makes alarm if distance is near from something of rear. The device makes break-system operate to prevent drivers from crashing if distance is so near. This device is portable. So normal deriver can set it easily.

Door guide rail is the core part which guides window when it moves up and down. But when the method of grease lubrication in the core has been used for a long times, its lubrication performance has been weakened. Therefore the method of the solid lubrication such as teflon(PTFE) coating in the rail has been studied to be increased the performance in these days. In this study the friction wear characteristic the surface with teflon coating of door guide rail for automobile has been researched. In 1, 20 Hz frequency friction wear tests the friction coefficient are below 0.188 and 0.213. In indicate test the wear depth is very slight. Therefore the durability to the friction wear in the surface with teflon coating of door guide rail is good. In addition to, the result of this study can make efficient use to a basic study to develop method of test evaluation to door guide rail surface grade. Especially this study will contribute to improve the quality of automobile parts.

In this study I construct CAN(Controller Area Network) for automobiles similar to LAN(Local Area Network) and build communication modules in the major part of an automobile to link several sub-systems. Since each station replaces the communication function of sub-systems and has various types of sensor, actuator, controller, and switch, every information about automobile's status is obtained from the network. The manufactured system showed a superior capability. The following is the contents of study. 1. The definition of communication packet through the analysis of CAN protocol. 2. The Design of modules using micro-controller 80C196CA. 3. The Network configuration.
