1, the detour route providing system 100 is connected to the navigation terminal 200 through a wireless communication network.

The navigation terminal 200 receives the destination information input from the driver of the vehicle and transmits it to the detour route providing system 100 and receives and outputs the travel route or the detour route from the detour route providing system 100. The navigation terminal 200 may be one of an AVN (Audio, Video, Navigation) terminal, a telematics terminal, an infotainment terminal, or a terminal of a vehicle occupant (driver or passenger).

The destination information receiving unit 110 receives the destination information transmitted from the navigation terminal 200.

When the destination information is received through the destination information receiving unit 110, the location information generating unit 120 receives the GPS signal transmitted from the GPS satellite, calculates the current location of the vehicle, and generates the location information.

The travel route calculating unit 130 calculates the travel route of the vehicle based on the destination information received through the destination information receiving unit 110 and the location information generated through the location information generating unit 120. [ According to the embodiment of the present invention, the travel route calculating unit 130 calculates the travel route having the shortest distance from the current position of the vehicle to the destination.

The section information database 140 stores road section information including the number of traffic lights for each road section, the average traffic volume for each time period, or the congestion time zone. In this case, the road section means a point between a predetermined point and a road, and the road section information means traffic information generated in the road section.

The estimated travel time calculating unit 150 calculates a time required until the vehicle reaches the destination (hereinafter referred to as "estimated travel time") when the vehicle travels along the travel route calculated through the travel route calculating unit 130 do. Specifically, the first estimated travel time is calculated based on the average speed of the vehicle stored in advance and the travel distance in the travel route calculated through the travel route calculating unit 130. [ Thereafter, the first travel forecasting time is corrected in accordance with the road section information stored in the section information database 140 and the weather information of the area corresponding to the travel route calculated through the travel route calculating unit 130, Calculate the time.

The congestion judging unit 160 judges whether or not the second travel estimated time calculated by the estimated travel time calculating unit 150 exceeds the predetermined threshold time based on the road segment information stored in the segment information database 140 And extracts a congestion prediction section in the route. At this time, the critical time is an average running time of the vehicles that have passed through the calculated travel route through the travel route calculating unit 130.

The driver information database 170 stores driving information of the overhead driver. According to the embodiment of the present invention, the driver information database 170 stores driving information of the selected driver in accordance with a preset reference among driving information of the driver transmitted from a plurality of vehicle or vehicle driver terminals. At this time, the driving information includes the current position of the driver who is driving the vehicle, the driving route of each road section, the driving time, the driving time, and the number of driving times.

When the deceleration of the moving vehicle is detected along the driving route, the detour route searching unit 180 matches the current position of the vehicle with the estimated congestion period calculated through the congestion determining unit 160 to determine whether or not the congestion period is entered, And searches the bypass route based on the route.

The bypass path searching unit 180 includes a first candidate group extracting unit 181, a second candidate group extracting unit 182, and an oldest driver selecting unit 183.

If the first candidate group extracting unit 181 determines that the vehicle enters the congestion expected section, the first candidate group extracting unit 181 extracts, based on the current position information of the driver who is driving the vehicle among the driving information stored in the driver information database 170, The driver of the vehicle located at the point where the vehicle is located is extracted as the first candidate group. Further, the driver of the vehicle located within a predetermined radius at the end of the congestion expected section can be extracted as the first candidate group.

The second candidate group extracting unit 182 extracts, as the second candidate group, the driver having the predetermined number or more of the driving paths corresponding to the congestion expected interval out of the first candidate groups extracted through the first candidate group extracting unit 181. [ According to the embodiment of the present invention, the second candidate group is extracted based on the driving route and the number of driving times for each road section in the driving information.

The old driver's selection unit 183 selects one driver who has passed the congestion prediction interval within the shortest time among the second candidate groups extracted through the second candidate group extraction unit 182. According to the embodiment of the present invention, the last available driver is selected based on the operating time zone, the required driving time, and the number of driving times among the driving information.

The travel route transmitting unit 190 transmits the calculated travel route through the travel route calculating unit 130 to the navigation terminal 200. In addition, the driving route of the selected driver is transmitted to the navigation terminal 200 through the driver's choice driver 183.

2 shows a method of providing a bypass route using the bypass route providing system of FIG.

First, destination information transmitted from the navigation terminal 200 is received through the destination information receiving unit 110 (S10).

When the destination information is received in step S10, the GPS signal transmitted from the GPS satellite is received through the position information generating unit 120 to generate current position information of the vehicle (S11).

Thereafter, the travel route calculating unit 130 calculates the travel route based on the destination information received in step S10 and the location information generated in step S11 (S12).

Thereafter, the expected travel time corresponding to the travel route calculated in step S12 is calculated through the estimated travel time calculating unit 150 (S13). Specifically, the first estimated travel time is calculated based on the road type, the average speed for each road type, and the travel distance for each road type of the travel route calculated in step S12, and the first travel estimated time, And the weather information of the area corresponding to the travel route calculated through the travel route calculating unit 130 to calculate the second travel expected time.

For example, assuming that the road type of the travel route calculated in step S12, the average speed of each road type, and the travel distance of each road type are shown in Table 1, the first travel expected time is' 130/100 Time) + 40/50 (expected travel time of the second section).

Road section Type of road Average speed Operating distance Section 1 highway 100 km / h 130 km The second section City road 50 km / h 40 km

When the first expected travel time is calculated, the correction value (the number of traffic lights) corresponding to the weather (sunrises, snow, rain, fog, etc.) in the area corresponding to the number of traffic lights, congestion time To calculate the second expected travel time.

Thereafter, the second operation estimated time calculated in step S13 is compared with a predetermined threshold time through the congestion determining unit 160 (S14).

As a result of the comparison in step S14, if the second expected travel time is equal to or less than the threshold time, the calculated travel route in step S12 is transmitted to the navigation terminal 200 (S15).

If the second operation expected time exceeds the threshold time, a congestion expected interval existing in the operation route calculated in operation S12 is extracted (S16). For example, it is possible to extract a congestion expected section existing in a route based on the number of traffic lights of each road section and the average traffic amount of each time section stored in the section information database 140.

 Thereafter, the first candidate group extracting unit 181 determines whether the vehicle enters a congestion expected section (S17), and selects a first nearest driver candidate group (S18). In the following, steps S17 and S18 will be described in detail with reference to FIG.

FIG. 3 shows a first candidate group selection method according to one embodiment of the present invention.

Referring to FIG. 3, when the deceleration of the moving vehicle is detected along the route, the current position of the vehicle is matched with the estimated congestion period calculated in step S16 to determine whether the congestion expected period of the vehicle is entered. As a result of the determination, when it is determined that the vehicle enters the congestion expected section, based on the running information of the oldest driver stored in the driver information database 170, within a predetermined radius A The driver of the located vehicle is selected as the first candidate group.

Returning to the description of FIG. 2, a driver having a predetermined number or more of operating routes corresponding to the congestion expected section among the first candidate groups selected in step S18 is selected as the second candidate group (S19).

Then, among the second candidate groups selected in step S19, the driver having the greatest number of driving times among the shortest driving duration corresponding to the stagnant expected interval in the recent time zone is selected as the final nearest driver (S20).

For example, if the result of the second candidate group selection in step S19 is as shown in Table 2 below, the second driver may be selected as the final last driver in step S20.

operator Day time zone Road section Day driving time Driving frequency One 09:00:01 The second section 20 50 2 09:30:01 The second section 22 200 3 09:46:21 The second section 30 15 I 09:52:21 The second section 35 3

If the final last driver is selected in step S20, the driving route of the final last driver corresponding to the expected congestion period is transmitted to the navigation terminal 200 through the travel route transmitter 190 in step S21.

In the bypass route providing method according to the embodiment of the present invention, the step of calculating the travel route (S10 to S12) of receiving the destination information and generating the current position information of the vehicle has been described, but the present invention is not limited thereto, The estimated travel time is calculated (step S13), and steps S10 to S12 may be omitted.

According to the embodiment of the present invention, the vehicle driver can avoid the congestion expected period by using the operation route of the highly reliable driver as the bypass route in the congestion expected section, and reach the destination within a short time.
