If the location information of a great number of cars kept for business with telematics terminals is acquired and managed efficiently, this information forms the foundation for controlling cars and traffic flows. The studies on the pure spatial indices have focused on the efficient retrievals. However, the acquisition and management of the terminal location of moving objects are more important than the efficiency of the query processing in the moving object databases. Therefore, it will be need to adopt parallel processing system for the moving object databases which should maintain the object's current location as precise as possible. This paper proposes a location management system using CDMA communications of telematics terminals. More precisely, we propose a architecture of spatial indexing mobile objects using multiple processors, and also newly propose a method of splitting buckets using the properties of moving objects in order to minimize the number of database updates. We also propose a acquisition method for gathering the location information of moving objects and passing the information of the bucket extents in order to reduce the amount of passed messages between processors.

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.

최근 텔레매틱스 기술은 운전자와 차량, 차량과 외부의 정보들을 이용하여 다른 산업과의 융합이 급속히 진행되고 있으며, 다양한 서비스에 대한 요구 역시 점차 증가하는 추세이다. 최근에는 차량의 위치 및 궤적 데이터 정보 서비스뿐만 아니라 차량을 통한 차별화된 고객별 영업, 마케팅 및 서비스 제공에 대한 VRM이 대두되고 있다. VRM은 차량의 주행 정보, 과거 이동정보, 운전자의 정보 등과 같은 차량에 관련된 다양한 정보에서 특정 규칙과 추출된 패턴 정보를 기반으로 영업, 서비스 생산, 마케팅 전략을 수립 및 적용할 수 있도록 해주는 것으로 CRM과 유사하다고 할 수 있다. 따라서 본 논문에서는 기존의 CRM의 성공 요인에 대한 선행 연구를 검토해 VRM의 전략적 관점에서 프로세스에 준거하여 고객자산가치관리와 VRM의 핵심기능인 고객자산가치 관리역량을 통해 차량의 주행정보, 차량 정검 정보, 운전자의 정보 등과 같은 차량에 관련된 모든 정보를 VRM 프레임워크가 갖추어야 할 요소를 도출하고 텔레매틱스 기반 VRM 프레임워크 모델을 제안해보고자 한다.

Telematics is a compound word derived from telecommunication and informatics, which provides wireless data service such as traffic information, living information, remote control, maintenance and etc. in a vehicle using GPS(Global Positioning System) and telecommunication. Telematics acceptance was investigated to analyze characteristics of telematics service and its market by using a theoretical technology acceptance model based on literature review. In this paper, valid factors, influencing telematics service acceptance, have been drawn in terms of user ease-of-use, usefulness and service characteristics. Modified measuring variables were used by referring to previous researches.

Telematics is a wireless data communication system that provides various information services for driver's the safety or entertainment, and it makes drivers possible to use those services in the moving space, as if he/she is at home or at office. As telecommunication technology develops and Telematics market grows larger, standard platform for the intelligent telematics is required. This paper describes the structure and module control design of the intelligent telematics that recognizes driver's needs and pushes customized services to the driver at real-time.

The telematics data management deals with queries on stream data coming from moving cars. So the stream DBMS should process the large amount of data stream in real-time. In this article, previous research projects are analyzed in the aspects of query processing. And a hybrid model is introduced where query preprocessor is used to process all types of queries in one singe system. Decreasing cost and rapidly increasing Performance of devices may guarantee the utmost parallelism of the hybrid system. As a result, various types of stream DBMS queries could be processed in a uniform and efficient way in a single system.

As the need for telematics contents services due to the frequent traveling of people is increasing, it is necessary to provide various telematics contents by connecting and integrating current telematics contents which are collected and provided by each individual data provider. However, it is difficult to integrate or exchange the current telematics contents, because the data providers use different telematics contents models. Therefore, we propose a 'telematics contents gateway(TCG); system, which enables to integrate different telematics contents, so that the contents can be interoperable. The TCG can be a solution for several problems in the current telematics contents providing system. First of all, it has been impossible to search the contents without any information about data providers, because of the absence of metadata in the current systems. For this problem, TCG supports a search function based on a web-service technology. Second, TCG provides a common road network model for interoperability, and the model can be a solution to integrate different road network models into the common model. Moreover, integration algorithm for enhancing the correctness of integration will be proposed. In addition, it is designed by multi threads and multi queue structure. The TCG developed with C# on a windows system has been running and we verified that there was no information loss in the integration process. In addition, the speed of content integration and transfer satisfied the requirement of telematics services providers.

최근 센서와 모바일 기술의 발달에 따라 대용량 데이터 처리가 가능해지고, 유비쿼터스와 텔레매틱스 등의 도입으로 공간 데이터가 다양한 환경에 응용되거나 활용 분야가 점차 증가하고 있다. 기존의 수치지도 관리시스템은 공간 데이터를 도엽 단위로 관리하여 데이터의 구축이 용이하지만, 객체 단위의 데이터 구축, 관리, 제공 및 갱신을 효율적으로 지원하기 어렵다. 따라서 이 논문에서는 기존 도엽기반 시스템의 문제점을 해결하기위해 객체기반 UFID 부여방안, 연속성 표현, 객체 단위의 효율적인 갱신 및 이력관리를 위한 객체기반 공간 데이터 모델을 설계한다. 제안하는 객체기반의 공간 데이터 모델은 지형지물에 UFID를 부여하고 도엽 단위로 구축된 수치지도 데이터의 조인 연산을 통해 연속적인 표현이 가능하다. 아울러 갱신으로 인해 변경된 데이터를 이력 DB에 시간간격 단위로 저장, 관리하여 사용자에게 객체단위 이력 정보를 제공할 수 있다.
