Car Navigation System and Method for Navigation Service in facility of that}

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a vehicle navigation apparatus for guiding emergency facilities and the like in a facility, and a facility guidance method thereof.

Recently, when a driver inputs a destination, a route guidance service that searches for an optimal route from a current location to a destination and provides the driver with a searched route in the form of a voice and an image is popularized.

The route guidance service is provided by a vehicle navigation device equipped with various sensors such as a GPS (Global Positioning System) sensor, a vehicle speed sensor, a gyro sensor, and the vehicle driver uses the vehicle navigation device to provide a road information provider with current location and destination information. When transmitting, the road information provider calculates the optimal or shortest route guidance data from the current location to the destination by referring to the geographic information and the real-time traffic information, and transmits the calculated route guidance data to the vehicle navigation apparatus again.

The route guidance service provides the driver with the shortest or optimal route from the current location to the destination, thereby safely guiding the driver traveling on the transboundary road, and has an advantage of preparing for an unpredictable traffic situation.

However, the current navigation system has a drawback that when entering into a specific facility, such as a rest area, a large building or a department store, it is considered that the route has been departed and it is impossible to guide the inside of the facility.

In addition, when entering the radio shading area, such as the underground parking lot of the department store, there is a disadvantage that the interior of the facility is not made because it is impossible to receive GPS signals.

An object of the present invention is to devise in view of the above problems, when it is determined that the entry into the guide facility, a vehicle for guiding the inside of the facility using the guide information of the guide facility previously stored in a database It is to provide a navigation device and a method for guiding its facilities.

In addition, another object of the present invention is to guide the emergency facilities in the facility by using the facility guide information previously stored in a database form, thereby guiding the path of the radio wave shadow area, such as inside the building or underground where GPS signals are not received. It is to provide a vehicle navigation apparatus and its facility guidance method.

In addition, another object of the present invention, when selecting an emergency facility menu in a specific facility, by highlighting the facility guidance icon corresponding to the selected menu, thereby improving the visibility of the guidance icon and a vehicle navigation apparatus and its facility guidance method To provide.

DETAILED DESCRIPTION OF THE EMBODIMENTS Hereinafter, the configuration and application of embodiments of the present invention will be described with reference to the accompanying drawings, and the configuration and operation of the present invention shown and illustrated by the drawings will be described in at least one embodiment. By the technical spirit of the present invention described above and its core configuration and operation is not limited.

1 is a block diagram schematically showing a configuration of a vehicle navigation apparatus according to an embodiment of the present invention.

As shown in FIG. 1, the vehicle navigation apparatus according to the present invention includes a GPS receiver 110, an inputter 120, a controller 130, a storage 140, and a display 150.

A GPS (Global Positioning System) receiver receives location information from three or more GPS satellites. The location information is periodically transmitted from the GPS satellites, and includes the longitude and latitude information of the point.

The input unit 120 receives a destination or various selection signals set by a user.

The storage unit 140 stores a list of guide target facilities and guide information of the guide target facilities. The facility to be guided includes large facilities such as rest areas, department stores, landmark towers, and the like. The facility information includes information such as location, distance, and use of facilities existing in the facility. In addition, the storage unit 140 stores OD information for guiding a path in the guide facility in the form of a database.

The controller 130 determines that the guide target facility stored in the storage 140 is entered with reference to the location information received through the GPS receiver 110. Various methods for determining that the controller 130 has entered the guide target facility will be described by way of example.

First, when a destination to the destination is set, when the destination is input through the input unit 120, the controller 130 searches for a path to the destination input through the input unit 120. When the departure of the path is detected when driving along the searched route, the storage unit 140 searches for the guidance target facility near the location information of the driving vehicle and determines that the guidance target facility has been entered.

Second, when a route to the destination is not set, the controller 130 provides a list of guide target facilities located within a predetermined range of the driving vehicle. In addition, the input unit 120 receives a selection signal for selecting any one of the guide target facilities included in the provided guide target facility list. Then, it is determined that entering the guidance target facility corresponding to the received selection signal. In this case, when the guidance target facility selection signal is not input through the input unit 120, it may be determined that the nearest guidance target facility is entered based on the driving position of the driving vehicle.

Third, in the case of the shaded region where the GPS signal is not received, the controller 140 extracts the region in which the driving vehicle last received the radio wave. In addition, a list of guide target facilities close to the region of the last received radio wave is provided, wherein the list of guide target facilities close to the location of the driving vehicle is provided. Next, when the guide facility selection signal is received through the input unit 120, it is determined that the selected guide facility has been entered.

When it is determined that the user enters the guide target facility in the same manner as described above, the controller 140 converts and displays the facility guide information stored in the storage unit 130 in the form of a simplified view or a schematic view. Mark the position of the vehicle on the road or schematic.

In addition, the control unit 140 displays the emergency facility menu information in the facility when the driving vehicle enters the guide facility, and the emergency facility is represented by a guide icon such as a text, an image, or a flash icon. . At this time, the emergency facility is set according to the utilization frequency, preference, etc. of the vehicle driver.

In addition, when the emergency facility menu information desired by the vehicle driver is selected through the input unit 120, the controller 140 changes the size, color, display cycle, etc. of the guide icon of the emergency facility corresponding to the selected menu information. To highlight. For example, if the guide icon of the selected emergency facility is a flash icon, an animation effect is applied to the flash icon to highlight it. In addition, if the emergency facility guide icon is selected, the selected emergency facility simultaneously displays detailed information in the form of Point of Interest (POI).

The display unit 150 displays emergency facility menu information, an emergency facility guide icon, and the like under the control of the controller 140.

Therefore, according to the present invention, by guiding the inside of the facility using the guide information of a specific guide target facility previously stored in a database, and highlighting the guide icon linked to the selected emergency facility menu information, the emergency inside the facility Emphasis on facilities has the advantage of increasing visibility.
