The present invention relates to a route guidance using a telematics terminal, and more particularly, when a vehicle enters a complicated road in the process of providing a route guidance to a destination set according to the movement of the vehicle equipped with the telematics terminal, a popup (Pop) is provided. The present invention relates to a route guidance system and a method using a telematics terminal to express a detailed configuration of a road network of a region in a schematic diagram to provide convenience for route selection on a complicated road.

In general, in order to provide a more accurate route guidance service using a vehicle-mounted navigation system, a GPS (Global Positioning System) positioning device, a communication device, and a large storage medium such as a CD-ROM or a hard disk storing geographic information are included. do.

The navigation system extracts the current vehicle location using a GPS positioning device or a position base service of a wireless communication network to guide the route to a set destination, and then maps the current location to the map information stored in the mass storage medium. By matching, the route to the destination set before the driver is guided through the display window in various ways.

In addition, when the driver's rerouting is requested in the process of driving to the set destination, the driver searches for the optimal route from the current location to the destination and guides the searched information in various ways.

The guidance of the above route does not accurately reflect the real-time traffic situation, but provides static information for setting and serving only a simple route.

In addition, the information on the searched route is provided as a turn-by-turn arrow and map information on the road image using voice guidance and computer graphics.

As such, the provision of static information for guiding a simple route to a destination has a disadvantage in that an active response is not accompanied when a situation of construction or an accident occurs on the route.

In addition, the route guidance provided by the computer graphics turn-by-turn (TBT) arrow and the map information has a certain degree of accuracy for intersections or simple roads, but lacks accuracy for complex intersections and three-dimensional intersections. There is a problem that causes confusion.

In severe cases, it is expressed differently from the actual road shape, causing the driver to select a different route.

The present invention has been invented to solve the above problems, the object is to provide a turn-by-turn (TBT) arrow, map information and voice guidance for the destination set according to the movement of the vehicle equipped with a telematics terminal When a vehicle enters a complicated road in the process of popping up, the detailed configuration of the road network of the region is displayed as a schematic diagram to provide convenience in selecting a route on a complicated road.

In addition, the route setting to the set destination can be made in the telematics center to provide miniaturization of the telematics terminal, and to provide the route guidance accurately reflecting the real-time traffic conditions according to the information processed and transmitted from the telematics center in real time. In the event of a yugo area, the telematics center will automatically set the detour route to guide you.

In addition, when leaving the route while driving to the set destination, the telematics terminal automatically requests the telematics re-search for the route, and receives and guides the reset route based on the location information of the GPS positioning device. The rerouting can be done.

The present invention for achieving the above object is a GPS; Select the target node for the pop-up display of the schematic diagram through the preliminary survey of each road, and select the guide section of the selected pop-up display target node, the latitude and longitude data (X, Y coordinates), the schematic assignment code, and the direction of the target node. The arrow code added to the schematic diagram is stored in the database for guiding, and when the route guidance is requested, the optimal route and the schematic popup target node included in the route and the general information related to the pop-up expression are extracted. A telematics center for transmitting the set protocol; A telematics terminal providing route guidance in a predetermined manner according to information provided from the telematics center, and pop-up-displaying the route guidance of the corresponding road as a schematic image when approaching a road for displaying a schematic pop-up while driving; It provides a route guidance system using a telematics terminal comprising a mobile communication network connecting the telematics center and the telematics terminal with a set protocol to relay a route setting request and route guidance data for a destination.

In addition, the present invention comprises the steps of setting a destination using a telematics terminal and then requesting a route guidance to a telematics center; Searching for an optimal route according to a route guidance request of the telematics terminal, extracting data related to a schematic set point and a schematic diagram, and transmitting the data to a telematics terminal; Extracting coordinate information from GPS information and providing route guidance by matching route coordinates provided by a telematics center; Providing a route map by providing a schematic diagram including detailed information on a road network of a corresponding area when a complex road is detected in a state of providing a route guide; The route guidance method using a telematics terminal comprising the step of clearing the pop-up of the schematic diagram and providing the route guidance in a basic manner when passing a complex road over a predetermined distance in the state of providing the route guidance as a pop-up of the schematic diagram. to provide.
