Hereinafter, an intersection guidance method using an intersection facility in navigation according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an intersection route guidance system to which the present invention is applied.

The intersection route guidance system according to the present invention includes a navigation map 1, a navigation module 2, a speaker 3 and a GPS module 4.

Such an intersection route guidance system refers to a navigation apparatus mounted on a vehicle.

The navigation map 1 represents map information including the line shape and background of the road, and facility information / attributes.

The GPS module 4 acquires position information and time information of the current vehicle through the GPS satellite and transmits the acquired position information and time information to the navigation module 2.

The navigation module 2 displays current position information obtained from the GPS module 4 on the navigation map 1 and controls the user to search for and search for a desired destination, And converts and processes the route information so that it can be recognized visually and audibly.

The speaker 3 interlocks with the navigation module 2 and transmits a route guidance voice output from the navigation module 2 to the outside.

FIG. 2 is a flowchart showing an intersection guidance method using an intersection facility in navigation according to the present invention, and is a flowchart showing a method of performing intersection guidance by software in the navigation module 2 of FIG.

As shown in FIG. 2, the intersection guidance method using the intersection facility in the navigation according to the present invention includes: (a) extracting the map rotation information when entering the intersection route guidance distance during route guidance in the destination setting S10); (b) extracting the intersection facility guide information and the voice guidance code from the extracted map rotation information (S20); (c) extracting the voice corresponding to the intersection facility guide information and the voice guidance code extracted at the step (b), and outputting the extracted voice to perform the intersection guidance (S30 to S40).

A navigation method using an intersection facility in a navigation system according to the present invention will now be described in detail with reference to FIGS. 1 to 4. FIG.

First, when an intersection route guidance system, which is a navigation device mounted on a vehicle, is operated, under the control of the navigation module 2, current position information is acquired in real time via the GPS module 4, (1) in real time.

Thereafter, when the user sets a destination, the navigation module 2 updates the current position information in real time on the navigation map 1 in the same manner as described above. When the navigation module 1 displays the position information on the navigation map 1, The voice guidance code is extracted and reproduced, and the voice guidance code is transmitted through the speaker 3. As a result, the driver is guided through the voice.

The navigation route guidance as described above is the same as the method of performing route guidance in general navigation.

If the voice guidance position is an intersection (S10), the map rotation information is extracted from the route guidance information stored in the internal memory during the route guidance through the video and audio after the destination setting in the manner described above (S20), and the route guidance for the direction of intersection rotation is performed based on the intersection facility information (S30, S40).

For example, when the vehicle enters the route guidance distance of the intersection (S10), the map rotation information is extracted as described above (S20).

As shown in FIG. 3A, the map rotation information includes ID information indicating a rotation information ID, Node information indicating a node ID, Road 1 information indicating an entry road, Road 2 information indicating an advancing road, Pass information Guide information indicating a voice guidance code, and Angle information indicating an entry road and an advance road turning angle. In the present invention, type code information indicating facility information of an intersection point is added to such general map rotation information, and facility information of an intersection is acquired when an intersection route guidance is performed.

The type code information is information indicating intersection facility information, and rotational direction information indicating a direction of rotation at an intersection is also mapped. Therefore, if the type code is extracted from the map rotation information, intersection rotation direction information can be also obtained.

As shown in FIG. 4, the type code information is composed of a major category, a small category, and a type code. The major category is information consisting of items such as gasoline, 24-hour convenience store, and bank. The sub category is classified into sub categories . For example, when the main category is oil, the sub categories refer to information such as SK Energy, GS Caltex, S-OIL, and OILBANK. In each subclass, a type code is mapped corresponding to 1: 1. That is, if the major category is gasoline and the minor category is SK energy, the category code is 1.

Therefore, if the type code is 1, the facilities to be rotated at the intersection are the gas stations, and if the direction of rotation mapped to them is linked, it is possible to know which direction the gas station turns at which intersection.

In step S30, a voice guidance code according to the type code is extracted, and a route guidance voice is extracted based on the extracted voice guidance code. At this time, a concrete intersection route guidance screen is displayed as usual even through the screen of the navigation.

In step S40, the extracted route guidance voice is transmitted through the speaker 3 so that the driver can receive the route guidance at the intersection by voice.

Here, the route guidance voice is the same as the guidance voice of the present invention in the table of FIG.

For example, when the voice guidance code is 1, the conventional route guidance voice is equal to "(in front of ~ m) left direction", but the route guidance voice according to the present invention is " Direction. " In other words, the route of the intersection is informed specifically based on intersection facility information, such as the direction to the left of SK energy intersection in front of ~ m.

Thus, the driver can acquire route information on the turning direction accurately based on the facility information at the intersection using only the hearing, so that it is unnecessary to look at the navigation screen at the intersection. As a result, it is possible to eliminate the inattentiveness of the forward sight which occurs when the intersection is watched the map information of the navigation screen and recognizes which direction the intersection is to be rotated as in the conventional manner. Therefore, it is possible to prevent a traffic accident .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It is obvious to those who have.
