And is intended to enable a person skilled in the art to readily understand the scope of the invention, and the invention is defined by the claims. It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. In the present specification, the singular form includes plural forms unless otherwise specified in the specification. It is noted that " comprises, " or "comprising," as used herein, means the presence or absence of one or more other components, steps, operations, and / Do not exclude the addition.

1 to 4, an AVN system and route guidance method according to an embodiment of the present invention will be described. 1 and 2 are conceptual diagrams for explaining an AVN system and a route guidance method according to an embodiment of the present invention, Figure 3 is a block diagram showing an AVN system according to an embodiment of the present invention, Figure 4 is a view of the present invention A flowchart illustrating a route guidance method according to an embodiment.

First, referring to FIGS. 1 and 2, the AVN system 100 according to an embodiment of the present invention uses real-time traffic information in an area having a radius of R1 or less from the starting point when searching for a route from the starting point to the destination. If the current location of the vehicle is within the radius of R1 and within R2, the route is searched and guided by using real-time traffic information and cumulative traffic information. If present in the area over R2, the route is searched and guided using the cumulative traffic information.

When a route is searched using real-time traffic information at the starting point, the real-time traffic information at the starting point is valid only in a certain area or within a certain time, so that the radius of the starting point beyond the R2 (that is, the effectiveness of the real-time traffic at the starting point) If the vehicle is located at the disappearance point, the route is searched by using the accumulated traffic information without using real-time traffic information. In addition, by using the cumulative traffic information without using the server data, the route search can be efficiently performed even in a situation where it is difficult to access the server.

An AVN system and a route guidance method according to an embodiment of the present invention will be further described with reference to FIGS. 3 and 4.

As shown in FIG. 3, the AVN system 100 according to an exemplary embodiment of the present invention includes a real-time traffic information receiver 110, a route search unit 120, and a cumulative traffic authority storage unit 130.

The traffic information receiver 110 receives real-time traffic information, and the cumulative traffic government storage 130 accumulates and stores traffic information according to the operation of the vehicle. In detail, the cumulative traffic information storage unit 130 accumulates traffic information according to the operation and stores the traffic information according to the day of the week, and arranges it in a specific holiday and holiday time zone. Accumulated traffic information includes average speed information of the corresponding road. The cumulative traffic information may be stored in binary data form or text form.

The route search unit 120 searches for a route using real-time traffic information at the departure point (S410), and performs route guidance using the found route (S420).

In operation S430, it is determined whether the radius R from the starting point to the current position of the vehicle is greater than the first reference radius R1. If it is not large, continue using the searched route.

If large, it is determined whether the radius R up to the current position of the vehicle is greater than the second reference radius R2 (S440).

If not large, that is, if the current location of the vehicle is greater than the first reference radius and less than the second reference radius from the starting point, the route search unit 120 searches for a route by combining real-time traffic information and cumulative traffic information received at the starting point. In step S450, route guidance is performed using the searched route in step S470.

If the radius R to the current position of the vehicle is larger than the second reference radius R2, that is, the current position of the vehicle is larger than the second reference radius from the starting point, the route search unit 120 may calculate only the accumulated traffic information. The route is searched using the searched route (S460), and the route guidance is performed using the searched route (S470). For example, the route search unit 120 may extract the speed information of the current day of the week and the time zone of the corresponding road from the cumulative traffic information storage unit 130, and search the route of the shortest time using the same. Alternatively, in case of a specific day or holiday, the route may be searched by using traffic information for the specific day and holiday time separately arranged.
