It is provided to fully convey the scope of the invention to those skilled in the art, and the present invention is defined only by the scope of 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. As used herein, “comprises” and / or “comprising” refers to the presence of one or more other components, steps, operations and / or elements. Or does not exclude additions.

Hereinafter, a method and apparatus for searching a route according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a screen illustrating an example of atmospheric environment information that may be used in a route searching method and apparatus according to an exemplary embodiment of the present invention. For example, Mogen, TPEG service, etc. currently being serviced may be utilized, and the atmospheric environment information provided includes nitrogen dioxide, ozone, carbon monoxide, sulfur dioxide, and fine dust information.

2 is a block diagram showing the configuration of a route search apparatus according to an embodiment of the present invention.

As shown in FIG. 2, the route search apparatus 200 according to the embodiment of the present invention includes a communication module 230, a route search module 220, and a map display module 210.

The communication module 230 receives the air environment information for each region from a server (not shown) that provides air environment information as shown in FIG. 1 through a wireless communication network, thereby internal memory (not shown) of the route search apparatus 200. ). In addition, if necessary, the communication module 230 may receive air environment information in real time and use the same to search a route.

The map display module 210 may display the same air environment information for each region obtained as described above while displaying the same map as in the conventional navigation device. Accordingly, the driver can visually easily recognize the air pollution state of the area displayed on the map.

The route search module 220 has a basic route search function that connects a departure point and a destination, and links an internal region of an administrative region or a road of a corresponding region according to the pollution degree of regional atmospheric environment information obtained from the communication module 230. Gives different search weights for.

That is, by assigning a high weight to the target road in the region with high pollution degree, the route can be avoided from the route by calculating the route by the minimum cost calculation method. Conversely, roads in areas with low pollution are set low in weight to increase selectivity.

For example, in the state in which the atmospheric environment information as shown in FIG. 1 is obtained, it can be seen that the atmospheric state of the Jungnang-gu area indicated by a yellow ③ is relatively poor compared to other regions. Can be used to provide a search path that does not pass through this area.

Now, a path searching method according to an embodiment of the present invention will be described. 3 is a flowchart illustrating a path searching method according to an embodiment of the present invention.

As shown in FIG. 3, the start / local location is checked (S310), and when the arrival / destination location is input (S320), a general route search between the starting point and the destination is performed (S330). The general path search is performed in the same way as the path search provided in a conventional navigation device.

When the user selects the search for the well-being path (S340), a weight is assigned according to the air pollution degree for each target road on the searched path (S350). At this time, air pollution information as shown in Fig. 1 is used. If the weight is given to each road, the search route of the least cost is selected from the path from the starting point to the destination (S360).

If the user does not select a well-being path, the user may guide the path according to the general path search performed in step S330.

Meanwhile, when a vehicle approaches an area in which specific atmospheric environment information exists, the measurement result of the area may be provided to the driver in a visual and audio manner. For example, if you are approaching an area with very low air pollution, provide voice prompts and / or on-screen indications such as "I feel better if I open a window and take a deep deep breath because the air in this area is clean," When approaching areas with high air pollution, voice prompts and / or on-screen displays may be provided, such as "Air in this area is rather polluted, please close the windows and maintain internal circulation."

As described above, according to an exemplary embodiment of the present invention, it is possible to reach a destination by avoiding a region having high air pollution, which is effective for the health and safety of the driver, and an environmentally friendly effect of reducing the impact on air pollution can be obtained.
