Abstract: A navigation system for a vehicle and a navigation method for the same are disclosed. The navigation system collects transportation information and fuel efficiency information from several source vehicles located in a specific region, generates an optimum route for the corresponding region, and informs a target vehicle having requested a navigation service of the optimum route, resulting in the implementation of more effective navigation service.

Abstract: Provided is a system for providing point of interest (POI) information includes a database configured to store the POI information corresponding to a name and identification information of each POI; a data communication module configured to extract the name and the identification information of the POI, which is extracted from a particular website by a first terminal and stored in a user designated path; and a control module configured to extract, from the database, the POI information corresponding to the name and the identification information of the POI extracted by the data communication module and transmit the POI information to the first terminal or a second terminal that is pre-defined.

Abstract: The present invention provides a traffic information providing system and terminal and a method of providing traffic information. More specifically, the traffic information providing system includes a first module, within a vehicle, which is configured to receive a range associated with a route calculated by a terminal from a web server, wherein a plurality of ranges are previously set based on a traveling route, a specific region and a present position. Additionally the present invention also includes a second module that is configured to receive a traffic information request for any one of a plurality of ranges from the terminal via a command. A third module is configured to collect traffic information within the provided range corresponding to the command. Upon doing so the second module transmits the traffic information collected by the third module to the traffic information providing terminal to be conveyed to the driver.

Abstract: A route guidance system, a car-audio apparatus thereof, and a method for providing route guidance using the same are provided. The route guidance system using a car-audio apparatus which includes an input module for receiving destination information to be visited by a driver from the driver via, e.g. a voice command, a location tracking module which determines a present location information of a vehicle, and a control module which transfers voice information for the present location information of the vehicle and the destination information to the server. Route guidance information, received from the server, is searched via an electronic map on the server. The control module transfers the route guidance information to the car-audio apparatus and allows the car-audio apparatus to display the route information through an interface of a display module of the car-audio apparatus.

Abstract: A vehicle management system and method which analyze diagnostic trouble codes (DTCs) of the past having the same driver environment in order to predict the trouble probability for diagnostic target items in advance and provide the analyzed result to the driver so that the trouble and/or a car accident due to the trouble can be prevented.

Abstract: A technology is provided that improves reliability of traffic information guidance by reflecting traffic information for each turning direction. A system of providing traffic information with intersection turning information includes a vehicle information collection unit is configured to collect vehicle information and a control unit is configured to calculate general link speed, travelling speed for each turning direction and link speed for each turning direction at an intersection using the collected vehicle information.

Abstract: A navigation system for a vehicle and a navigation method for the same are disclosed. The navigation system collects transportation information and fuel efficiency information from several source vehicles located in a specific region, generates an optimum route for the corresponding region, and informs a target vehicle having requested a navigation service of the optimum route, resulting in the implementation of more effective navigation service.

Abstract: The present invention provides a method of estimating traffic information of a road section at a particular time point on the basis of the traffic information of the road at the time point or points before the particular time point and the traffic information of the adjacent roads.

Abstract: The present invention provides a terminal for collecting traffic information generates a data set, including information about a measurement start point and a travel locus, periodically measured for a predetermined period from the start point, using DR information based on DR and GPS information, and transmits the data set to a remote traffic information center. The start point includes a vehicle ID, and absolute coordinates and an absolute time at the start point, and the travel locus information includes relative coordinates of each measurement location with respect to a previous measurement location. A method for generating traffic information in a remote traffic information center using information collected from the terminal is also provided.
