Referring to FIG. 1, a route guidance apparatus according to an embodiment of the present invention includes a vehicle device 10, a navigation terminal 20, and a service server 30.

The vehicle device 10 is installed in the vehicle, detects the driving state of the vehicle, analyzes the sensed traveling state, detects the position information of the driving inconvenience point according to the analysis result, and transmits the sensed position information to the service server 30 do.

Driving inconvenience point is the point where driving is inconvenient due to the cause of road surface condition and so on. The driving inconvenience point may include a point where a road breakage point, a plurality of speeding bumps are continuously installed, a point where the road surface is uneven, such as an unpaved road, and the like. Anything other than a driving inconvenience point may be included.

2, the vehicle 10 includes a traveling state sensing unit 11, a position sensing unit 12, a photographing unit 13, and a control unit 14.

The running state detection unit 11 detects the running state of the vehicle. The running state sensing unit 11 includes a vibration sensing unit 111 and an acceleration sensing unit 112.

The vibration sensing unit 111 senses the vibration of the vehicle.

The acceleration sensing unit 112 senses the acceleration of the vehicle.

The running state of the vehicle is for checking whether the current running point of the vehicle is a driving inconvenient point.

As described above, the driving inconvenience point is a point at which a road breakage point or a plurality of speed limiting bumps are continuously installed or the road surface is uneven. Therefore, when the vehicle passes the driving inconvenience point, the speed of the vehicle suddenly decreases or the vehicle vibrates.

Accordingly, the acceleration and the vibration of the vehicle can be analyzed to check whether or not the vehicle is running on a driving inconvenience point.

The position sensing unit 12 senses the current position of the vehicle. A GPS (Global Positioning System) module may be employed as the position sensing unit 12. [ The GPS module calculates distance information from three or more satellites and time information on the measured distance information, and then calculates the three-dimensional position information according to the latitude, longitude, and altitude by applying trigonometry to the calculated distance information.

The photographing section 13 photographs the surroundings of the vehicle. The photographing unit 13 may be a camera installed in the navigation terminal 20 or a camera installed in a black box. In addition, various photographing devices capable of photographing the surroundings of the vehicle can be employed as the photographing unit 13.

The control unit 14 detects the position information of the driving inconvenience point using the driving state of the vehicle sensed by the driving state sensing unit 11 and the position of the vehicle sensed by the position sensing unit 12, And transmits the location information of the inconvenience point to the service server 30.

That is, the control unit 14 detects the position information of the driving inconvenience point through the position sensing unit 12 according to whether the running state of the vehicle, for example, the vibration and acceleration of the vehicle, And transmits the position information of the detected operation inconvenience point to the service server 30.

Here, the detection condition is set for each of the vibration and the acceleration of the vehicle, and is a reference for recognizing whether the vehicle is currently running a driving inconvenience point.

For example, when the vibration sensed by the vibration sensing unit 111 is repeated more than a preset vibration frequency by a predetermined vibration amount or more, the control unit 14 recognizes the current driving position as a driving inconvenience point. The control unit 14 detects the present position of the vehicle through the position sensing unit 12 and transmits the sensed position information to the service server 30. [

If the number of times the acceleration sensed by the acceleration sensing unit 112 is lower than the set acceleration but is decelerated more than the set acceleration continuously exceeds the set deceleration number, the control unit 14 determines that the current driving point is a driving inconvenience point . The control unit 14 detects the current position of the vehicle through the position sensing unit 12 and transmits the sensed position information to the service server 30 as described above do.

Further, when the control unit 14 recognizes the current driving point through one or more of acceleration and vibration of the vehicle as a driving inconvenience point, the control unit 14 photographs the surroundings of the vehicle through the photographing unit 13 and transmits the photographed image to the service server 30 ).

The image of the surroundings of the vehicle photographed through the photographing unit 13 is used to judge whether a driving inconvenience point is caused by a vehicle accident or a road condition. This will be described later.

The navigation terminal 20 recognizes its current position through a Global Positioning System (GPS) satellite, transmits its position and destination to the service server 30, and requests navigation to the destination.

Then, the navigation terminal 20 guides the route to the destination, for example, the main route or the alternative route, which is transmitted from the service server 30, to the driver. In this case, the navigation terminal 20 displays the route to the destination on the map, displays the current position of the vehicle by matching the map, and guides the route to the destination by voice. In this case, the navigation terminal 20 can further provide various traffic conditions and guidance information on the route.

For reference, in the present embodiment, the vehicle device 10 and the navigation terminal 20 are independently installed. However, the vehicle device 10 and the navigation terminal 20 may be coupled to each other and installed in the same vehicle.

3, the service server 30 includes a control server 32 and a database unit 31. [

The database unit 31 stores the position information of the driving inconvenience point transmitted from the vehicle device 10. [

The control server 32 analyzes the image transmitted from the vehicle device 10, determines the cause of the inconvenience point according to the analysis result, and selectively filters the inconvenience point information according to the determination result.

For example, the control server 32 determines whether a driving inconvenience point is caused by an accident or a driving inconvenience point is caused by a road condition as a result of analyzing the image transmitted from the vehicle device 10, The position information of the driving inconvenience point generated by the accident is filtered so that only the position information of the driving inconvenience point caused by the road condition is stored in the database unit 31. [

Here, whether or not the driving inconvenience point is caused by an accident or whether the driving inconvenience point is caused by the road condition can be determined through the number of the excessive speed bumps, whether or not the lane on the road surface is detected, and the like.

In addition, whether the driving inconvenience point is caused by an accident or whether the driving inconvenience point is caused by the road condition can be directly selected from the manager or the like, and in this case, It is possible to filter the location information of the inconvenience point and to store only the location information of the inconvenience point caused by the road condition.

When the control server 32 is requested to search for the route from the navigation terminal 20 to the destination, the control server 32 searches for the main route to the destination. Here, the main route is a route that does not avoid a driving inconvenience point, that is, a route that does not take position information of a driving inconvenience point into consideration.

Next, the control server 32 detects the location information of the driving inconvenience point in the database unit 31, determines whether or not the position information of the driving inconvenience point exists on the main path, The navigation terminal 20 searches for an alternative route avoiding the driving inconvenience point and transmits the retrieved alternative route to the navigation terminal 20.

In particular, when the main path and the alternative path are searched, the control server 32 compares the main path and the alternative path, and selects either the main path or the alternative path as shown in FIGS. 4 and 5, respectively, .

The control server 32 may provide the main path to the destination as shown in FIG.

However, if there is a driving inconvenience point (a large number of vibrations due to road damage) on the main path, the control server 32 provides an alternative path that bypasses the driving inconvenience point as shown in Fig.

In this case, the control server 32 determines whether the ratio of the distance corresponding to the driving inconvenience point to the entire distance of the main path is equal to or less than a predetermined set distance ratio, The main path is provided to the navigation terminal 20. If the ratio of the distance corresponding to the driving inconvenience point to the entire distance of the main path exceeds the set distance ratio, And provides it to the navigation terminal 20.

In addition, the control server 32 compares the time, distance, and cost of each of the main path and the alternative path, respectively. If the time of the main path is longer than the time of the alternative route or the distance of the main path is longer than the distance of the alternative route or the cost of the alternative route is larger than the cost of the main route, And transmits it to the terminal 20.

On the other hand, if the time of the main path is smaller than the time of the alternative path, or if the distance of the main path is closer to the distance of the alternative path or the cost of the alternative path is smaller than that of the main path And transmits the alternative route to the navigation terminal 20.

As described above, if the current driving position is recognized as a driving inconvenience point through at least one of acceleration and vibration of the vehicle, the control unit 14 detects the current position of the vehicle through the position sensing unit 12, The surrounding image is photographed through the camera 13 (S140).

Then, the control unit 14 transmits the position information of the operation inconvenience point and the video around the vehicle to the service server 30 (S150). Accordingly, the service server 30 stores the location information of the driving inconvenience point transmitted from the vehicle device 10 and the image around the vehicle.

Referring to FIG. 7, the control server 32 acquires position information of a driving inconvenience point and images of the surroundings of the vehicle from at least one vehicle device 10 (S210).

The control server 32 analyzes the image transmitted from the vehicle device 10 to determine whether the driving inconvenience point is a driving inconvenience point caused by an accident or a driving inconvenience point caused by the road condition, The position information of the generated driving inconvenience point is filtered (S220).

In this case, whether or not the driving inconvenience point is caused by an accident or whether the driving inconvenience point is caused by the road condition can be determined through the number of the excessive speed bumps, the detection of the lane on the road surface, and the like.

In addition, whether the driving inconvenience point is caused by an accident or whether the driving inconvenience point is caused by the road condition may be directly selected from the manager or the like.

On the other hand, the control server 32 filters the position information of the driving inconvenience point generated by the accident as described above, and stores the position information of the driving inconvenience point generated by the road condition in the database unit 31 (S230 ).

Next, the control server 32 detects the location information of the driving inconvenience point in the database unit 31 and determines whether the location information of the driving inconvenience point exists on the main path (S330).

If it is determined in step S330 that the location information of the driving inconvenience point does not exist on the main path, the control server 32 provides the main path through the navigation terminal 20 (S340).

On the other hand, if it is determined in step S330 that the location information of the driving inconvenience point exists on the main path, the control server 32 searches for an alternative path avoiding the driving inconvenience point (S350).

As described above, the control server 32 compares the main path and the alternative path according to the search for the main path and the alternative path, and provides either the main path or the alternative path according to the comparison result (S360).

In this case, the control server 32 determines whether the ratio of the distance corresponding to the driving inconvenience point to the entire distance of the main path is equal to or less than a predetermined set distance ratio, When the ratio of the distance corresponding to the driving disturbance point to the driving disturbance point is less than the set distance ratio, the main path is provided through the navigation terminal 20. If the ratio of the distance corresponding to the driving inconvenience point to the entire distance of the main path exceeds the set distance ratio, To the navigation terminal 20 via the navigation terminal 20.

Further, the control server 32 compares the time, distance, and cost of each of the main path and the alternative path, respectively, and determines whether the time of the main path is longer than the time of the alternative path or the distance of the main path is longer than the distance of the alternative path Or provides the main path through the navigation terminal 20 if the cost of the alternative path is greater than the cost of the main path.
